Owner also reserves the right to waive all informalities not involving price, time, or changes in the Work and to negotiate contract terms with the Successful Bidder. 19.02 More than one Bid for the same Work from an individual or entity under the same or different names will not be considered. Reasonable grounds for believing that any Bidder has an interest in more than one Bid for the Work may be cause for disqualification of that Bidder and the rejection of all Bids in which that Bidder has an interest. 19.03 In evaluating Bids, Owner will consider whether or not the Bids comply with the prescribed requirements, and such alternates, unit prices and other data, as may be requested in the Bid Form or prior to the Notice of Award. 19.04 In evaluating Bidders, Owner will consider the qualifications of Bidders and may consider the qualifications and experience of Subcontractors, Suppliers, and other individuals or entities proposed for those portions of the Work for which the identity of Subcontractors, Suppliers, and other individuals or entities must be submitted as provided in the Supplementary Conditions. 19.05 Owner may conduct such investigations as Owner deems necessary to establish the responsibility, qualifications, and financial ability of Bidders, proposed Subcontractors, Suppliers, individuals, or entities to perform the Work in accordance with the Contract Documents. 19.06 If the contract is to be awarded, it will be awarded to the Bidder who submits the lowest responsive, responsible bid and whose evaluation by Owner indicates that the award will be in the best interests of the Project. 19.07 If the contract is intended to be awarded, Owner will issue a written Notice of Intent to Award to each Bidder who submitted a Bid at least ten (10) days before the award of a Contract.

The written protest shall, at a minimum, set forth the specific reasons why the protester believes that the contract should not be awarded to the apparent low Bidder and certify that the Protester’s Bid is itself responsive in all respects to the Owner’s Bidding requirements.

The Contractor is required to include in each subcontract for property or services entered into by the Contractor and a first‐tier subcontractor, including a material supplier, for the purpose of performing this construction contract: 1. A payment clause that obligates the Contractor to pay the first‐tier subcontractor for satisfactory performance under its subcontract within 10 days out of such amounts as are paid to the Contractor by the public contracting agency under such contract; and 2. An interest penalty clause that obligates the Contractor, if payment is not made within 30 days after receipt of payment from the Owner, to pay to the first‐tier subcontractor an interest penalty on amounts due in the case of each payment not made in accordance with the payment clause included in the subcontract pursuant to paragraph (a) of this subsection. A contractor or first‐tier subcontractor shall not be obligated to pay an interest penalty if the only reason that the contractor or first‐tier subcontractor did not make payment when payment was due is that the contractor or first‐tier subcontractor did not receive payment from the Owner or contractor when payment was due. The interest penalty shall be: a. For the period beginning on the day after the required payment date and ending on the date on which payment of the amount is due made; and b. Computed at the rate specified in 279C.570 (2). The Contractor is further required to include in each of its subcontracts, for the purpose of performance of such contract condition, a provision requiring the first‐tier subcontractor to include a payment clause and an interest penalty clause conforming to the standards of this section and require each of its subcontractors to include such clauses in their subcontracts with each lower‐tier subcontractor or supplier. The Contractor shall not request payment of any amount withheld or retained in accordance with ORS 279C.560(6) until such time as the Contractor has determined and certified to the Owner that the subcontractor is entitled to the payment of such amount. A dispute between the Contractor and a first‐tier subcontractor relating to the amount or entitlement of a subcontractor to a payment or a late payment interest penalty under a clause included in the subcontract pursuant to subsection (4) or (5) of ORS 279C.580 does not constitute a dispute to which the Owner is a party. The Owner shall not be included as a party in any administrative or judicial proceeding involving such a dispute.
PAYMENT OF LABORERS AND DRUG TESTING PROGRAM
1. The Contractor shall, to the extent as may be required by Oregon law: a. Make payment promptly, as due, to all persons supplying to such Contractor labor or material for the prosecution of the work provided for this contract; b. Workers shall be paid not less than the applicable state or federal prevailing wage rate, whichever is higher. ORS 279C.830(1)(c); OAR 839‐025‐0020(3) c. Pay all contributions or amounts due the Industrial Accident Fund by the Contractor or subcontractors, if permitted, incurred in the performance of this contract; d. Not permit any lien or claim to be filed or prosecuted against the Owner on account of any labor or material furnished; and e. Pay to the Department of Revenue all sums withheld from employees pursuant to ORS 316.167. f. Demonstrate that an employee drug testing program is in place during the term of this Contract. 2. If the Contractor fails to pay for labor and services, the Owner may pay for them and withhold these amounts from payments to the Contractor. ORS 279C.515; OAR 839‐025‐0020(2)(a). 3. If the contractor or a first‐tier subcontractor fails, neglects or refuses to make payment to a person furnishing labor or materials within 30 days after receipt of payment from the Owner or a contractor, the contractor or first‐tier subcontractor shall owe the person the amount due plus interest charges commencing at the end of the 10‐day period that payment is due under ORS 279C.580(4) and ending upon final payment, unless payment is subject to a good faith dispute as defined in ORS 279C.580. The rate of interest charged to the contractor or first‐tier subcontractor on the amount due shall equal three times the discount rate on 90‐day commercial paper in effect at the Federal Reserve Bank in the Federal Reserve district that includes Oregon on the date that is 30 days after the date when payment was received from the Owner or from the contractor, but the rate of interest shall not exceed 30 percent. The amount of interest may not be waived. 4. If requested in writing by a first‐tier subcontractor, the contractor, within 10 calendar days after receiving the request, shall send to the first‐tier subcontractor a copy of that portion of any invoice, request for payment submitted to the public contracting agency or pay document provided by the public contracting agency to the contractor specifically related to any labor or materials supplied by the first‐tier subcontractor. 5. This contract and every contract related to this contract shall contain a clause or condition that, if the contractor or a subcontractor fails, neglects or refuses to make payment to a person furnishing labor or materials in connection with the this contract, the person may file a complaint with the Construction Contractors Board, unless payment is subject to a good faith dispute as defined in ORS 279C.580. 6. The payment of a claim in this manner shall not relieve the Contractor or the Contractor's surety, if any, from obligation with respect to any unpaid claims.

TIME LIMITATION ON CLAIM FOR OVERTIME To the extent any of Contractor’s employees are covered by the Oregon employment laws, such covered worker employed by the Contractor shall be foreclosed from the right to collect for any overtime under this contract unless a claim for payment is filed with the Contractor within 90 days from the completion of the contract, providing the Contractor has: 1.

15‐175 Performance Bond ‐ 2
1. Contractor and Surety, jointly and severally, bind themselves, their heirs, executors, administrators, successors, and assigns to Owner for the performance of the Contract, which is incorporated herein by reference. 2. If Contractor performs the Contract, Surety and Contractor have no obligation under this Bond, except to participate in conferences as provided in Paragraph 3.1. 3. If there is no Owner Default, Surety's obligation under this Bond shall arise after:
3.1. Owner has notified Contractor and Surety, at the addresses described in Paragraph 10 below, that Owner is considering declaring a Contractor Default and has requested and attempted to arrange a conference with Contractor and Surety to be held not later than 15 days after receipt of such notice to discuss methods of performing the Contract. If Owner, Contractor and Surety agree, Contractor shall be allowed a reasonable time to perform the Contract, but such an agreement shall not waive Owner's right, if any, subsequently to declare a Contractor Default; and
3.2. Owner has declared a Contractor Default and
formally terminated Contractor's right to complete the Contract. Such Contractor Default shall not be declared earlier than 20 days after Contractor and Surety have received notice as provided in Paragraph 3.1; and
3.3. Owner has agreed to pay the Balance of the
Contract Price to:
1. Surety in accordance with the terms of the Contract;
2. Another contractor selected pursuant to Paragraph 4.3 to perform the Contract.
4. When Owner has satisfied the conditions of Paragraph 3, Surety shall promptly and at Surety's expense take one of the following actions:
4.1. Arrange for Contractor, with consent of Owner, to perform and complete the Contract; or
4.2. Undertake to perform and complete the Contract
itself, through its agents or through independent contractors; or
4.3. Obtain bids or negotiated proposals from qualified contractors acceptable to Owner for a contract for performance and completion of the Contract, arrange for a contract to be prepared for execution by Owner and Contractor selected with Owner's concurrence, to be secured with performance and payment bonds executed by a qualified surety equivalent to the bonds issued on the Contract, and pay to Owner the amount of damages as described in Paragraph 6 in excess of the Balance of the Contract Price incurred by Owner resulting from Contractor Default; or
4.4. Waive its right to perform and complete, arrange
for completion, or obtain a new contractor and with reasonable promptness under the circumstances:
1. After investigation, determine the amount for which it may be liable to Owner and, as soon as practicable after the amount is determined, tender payment therefor to Owner; or
2. Deny liability in whole or in part and notify Owner citing reasons therefor.
5. If Surety does not proceed as provided in Paragraph 4 with reasonable promptness, Surety shall be deemed to be in default on this Bond 15 days after receipt of an additional written notice from Owner to Surety demanding that Surety perform its obligations under this Bond, and Owner shall be entitled to enforce any remedy available to Owner. If Surety proceeds as provided in Paragraph 4.4, and Owner refuses the payment tendered or Surety has denied liability, in whole or in part, without further notice Owner shall be entitled to enforce any remedy available to Owner. 6. After Owner has terminated Contractor's right to complete the Contract, and if Surety elects to act under Paragraph 4.1, 4.2, or 4.3 above, then the responsibilities of Surety to Owner shall not be greater than those of Contractor under the Contract, and the responsibilities of Owner to Surety shall not be greater than those of Owner under the Contract. To a limit of the amount of this Bond, but subject to commitment by Owner of the Balance of the Contract Price to mitigation of costs and damages on the Contract, Surety is obligated without duplication for:
6.1. The responsibilities of Contractor for correction of defective Work and completion of the Contract;
6.2. Additional legal, design professional, and delay
15‐175 Performance Bond ‐ 3
costs resulting from Contractor's Default, and resulting from the actions or failure to act of Surety under Paragraph 4; and
6.3. Liquidated damages, or if no liquidated damages
are specified in the Contract, actual damages caused by delayed performance or non‐performance of Contractor.
7. Surety shall not be liable to Owner or others for obligations of Contractor that are unrelated to the Contract, and the Balance of the Contract Price shall not be reduced or set off on account of any such unrelated obligations. No right of action shall accrue on this Bond to any person or entity other than Owner or its heirs, executors, administrators, or successors. 8. Surety hereby waives notice of any change, including changes of time, to Contract or to related subcontracts, purchase orders, and other obligations. 9. Any proceeding, legal or equitable, under this Bond may be instituted in any court of competent jurisdiction in the location in which the Work or part of the Work is located and shall be instituted within two years after Contractor Default or within two years after Contractor ceased working or within two years after Surety refuses or fails to perform its obligations under this Bond, whichever occurs first. If the provisions of this paragraph are void or prohibited by law, the minimum period of limitation available to sureties as a defense in the jurisdiction of the suit shall be applicable. 10. Notice to Surety, Owner, or Contractor shall be mailed or delivered to the address shown on the signature page.
11. When this Bond has been furnished to comply with a statutory requirement in the location where the Contract was to be performed, any provision in this Bond conflicting with said statutory requirement shall be deemed deleted herefrom and provisions conforming to such statutory requirement shall be deemed incorporated herein. The intent is that this Bond shall be construed as a statutory bond and not as a common law bond. 12. Definitions.
12.1 Balance of the Contract Price: The total amount payable by Owner to Contractor under the Contract after all proper adjustments have been made, including allowance to Contractor of any amounts received or to be received by Owner in settlement of insurance or other Claims for damages to which Contractor is entitled, reduced by all valid and proper payments made to or on behalf of Contractor under the Contract.

all sums due Claimants, and 2.2. Defends, indemnifies, and holds harmless Owner
from all claims, demands, liens, or suits alleging non‐payment by Contractor by any person or entity who furnished labor, materials, or equipment for use in the performance of the Contract, provided Owner has promptly notified Contractor and Surety (at the addresses described in Paragraph 12) of any claims, demands, liens, or suits and tendered defense of such claims, demands, liens, or suits to Contractor and Surety, and provided there is no Owner Default.
3. With respect to Claimants, this obligation shall be null and void if Contractor promptly makes payment, directly or indirectly, for all sums due. 4. Surety shall have no obligation to Claimants under this Bond until: 4.1. Claimants who are employed by or have a direct

Any conclusion or information obtained or derived from such electronic files will be at the user’s
15‐175 General Conditions ‐10
sole risk. If there is a discrepancy between the electronic files and the hard copies, the hard copies govern. B. Because data stored in electronic media format can deteriorate or be modified inadvertently or otherwise without authorization of the data’s creator, the party receiving electronic files agrees that it will perform acceptance tests or procedures within 60 days, after which the receiving party shall be deemed to have accepted the data thus transferred. Any errors detected within the 60‐day acceptance period will be corrected by the transferring party. C. When transferring documents in electronic media format, the transferring party makes no representations as to long term compatibility, usability, or readability of documents resulting from the use of software application packages, operating systems, or computer hardware differing from those used by the data’s creator. ARTICLE 4 ‐ AVAILABILITY OF LANDS; SUBSURFACE AND PHYSICAL CONDITIONS; HAZARDOUS ENVIRONMENTAL CONDITIONS; REFERENCE POINTS
4.01 Availability of Lands A. Owner shall furnish the Site. Owner shall notify Contractor of any encumbrances or restrictions not of general application but specifically related to use of the Site with which Contractor must comply in performing the Work. Owner will obtain in a timely manner and pay for easements for permanent structures or permanent changes in existing facilities. If Contractor and Owner are unable to agree on entitlement to or on the amount or extent, if any, of any adjustment in the Contract Price or Contract Times, or both, as a result of any delay in Owner’s furnishing the Site or a part thereof, Contractor may make a Claim therefor as provided in Paragraph 10.05. B. Upon reasonable written request, Owner shall furnish Contractor with a current statement of record legal title and legal description of the lands upon which the Work is to be performed and Owner’s interest therein as necessary for giving notice of or filing a mechanic's or construction lien against such lands in accordance with applicable Laws and Regulations. C. Contractor shall provide for all additional lands and access thereto that may be required for temporary construction facilities or storage of materials and equipment.
4.02 Subsurface and Physical Conditions A. Reports and Drawings: The Supplementary Conditions identify: 1. those reports of explorations and tests of subsurface conditions at or contiguous to the Site that Engineer has used in preparing the Contract Documents; and 2. those drawings of physical conditions in or relating to existing surface or subsurface structures at or contiguous to the Site (except Underground Facilities) that Engineer has used in preparing the Contract Documents. B. Limited Reliance by Contractor on Technical Data Authorized: Contractor may rely upon the general accuracy of the “technical data” contained in such reports and drawings, but such reports and drawings are not Contract Documents. Such “technical data” is identi‐fied in the Supplementary Conditions. Except for such reliance on such “technical data,” Contractor may not rely upon or make any claim against Owner or Engineer, or any of their Related Entities with respect to: 1. the completeness of such reports and drawings for Contractor’s purposes, including, but not limited to, any aspects of the means, methods, techniques, sequences, and procedures of construction to be employed by Contractor, and safety precautions and programs incident thereto; or 2. other data, interpretations, opinions, and information contained in such reports or shown or indicated in such drawings; or 3. any Contractor interpretation of or conclusion drawn from any "technical data" or any such other data, interpretations, opinions, or information. 4.03 Differing Subsurface or Physical Conditions A. Notice: If Contractor believes that any subsur‐face or physical condition at or contiguous to the Site that is uncovered or revealed either: 1. is of such a nature as to establish that any “technical data” on which Contractor is entitled to rely as provided in Paragraph 4.02 is materially inaccurate; or 2. is of such a nature as to require a change in the Contract Documents; or 3. differs materially from that shown or indicated in the Contract Documents; or
15‐175 General Conditions ‐11
4. is of an unusual nature, and differs materially from conditions ordinarily encountered and generally recognized as inherent in work of the character provided for in the Contract Documents; then Contractor shall, promptly after becoming aware thereof and before further disturbing the subsurface or physical conditions or performing any Work in connec‐tion therewith (except in an emergency as required by Paragraph 6.16.A), notify Owner and Engineer in writing about such condition. Contractor shall not further disturb such condition or perform any Work in connection therewith (except as aforesaid) until receipt of written order to do so. B. Engineer’s Review: After receipt of written notice as required by Paragraph 4.03.A, Engineer will promptly review the pertinent condition, determine the necessity of Owner's obtaining additional exploration or tests with respect thereto, and advise Owner in writing (with a copy to Contractor) of Engineer’s findings and conclusions. C. Possible Price and Times Adjustments 1. The Contract Price or the Contract Times, or both, will be equitably adjusted to the extent that the existence of such differing subsurface or physical condition causes an increase or decrease in Contractor’s cost of, or time required for, performance of the Work; subject, however, to the following:
a. such condition must meet any one or more of the categories described in Paragraph 4.03.A; and b. with respect to Work that is paid for on a Unit Price Basis, any adjustment in Contract Price will be subject to the provisions of Paragraphs 9.07 and 11.03.
2. Contractor shall not be entitled to any adjustment in the Contract Price or Contract Times if:
a. Contractor knew of the existence of such conditions at the time Contractor made a final commitment to Owner with respect to Contract Price and Contract Times by the submission of a Bid or becoming bound under a negotiated contract; or b. the existence of such condition could reasonably have been discovered or revealed as a result of any examination, investigation, explo‐ration, test, or study of the Site and contiguous areas required by the Bidding Requirements or Contract Documents to be conducted by or for
Contractor prior to Contractor's making such final commitment; or c. Contractor failed to give the written notice as required by Paragraph 4.03.A.
3. If Owner and Contractor are unable to agree on entitlement to or on the amount or extent, if any, of any adjustment in the Contract Price or Contract Times, or both, a Claim may be made therefor as provided in Paragraph 10.05. However, Owner and Engineer, and any of their Related Entities shall not be liable to Contractor for any claims, costs, losses, or damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by Contractor on or in connection with any other project or anticipated project. 4.04 Underground Facilities A. Shown or Indicated: The information and data shown or indicated in the Contract Documents with respect to existing Underground Facilities at or contiguous to the Site is based on information and data furnished to Owner or Engineer by the owners of such Underground Facilities, including Owner, or by others. Unless it is otherwise expressly provided in the Sup‐plementary Conditions: 1. Owner and Engineer shall not be responsible for the accuracy or completeness of any such information or data; and 2. the cost of all of the following will be included in the Contract Price, and Contractor shall have full responsibility for:
a. reviewing and checking all such information and data, b. locating all Underground Facilities shown or indicated in the Contract Documents, c. coordination of the Work with the owners of such Underground Facilities, including Owner, during construction, and d. the safety and protection of all such Under‐ground Facilities and repairing any damage thereto resulting from the Work.
B. Not Shown or Indicated 1. If an Underground Facility is uncovered or revealed at or contiguous to the Site which was not shown or indicated, or not shown or indicated with

reasonable accuracy in the Contract Documents, Contractor shall, promptly after becoming aware thereof and before further disturbing conditions affected thereby or performing any Work in connection therewith (except in an emergency as required by Paragraph 6.16.A), identify the owner of such Underground Facility and give written notice to that owner and to Owner and Engineer. Engineer will promptly review the Underground Facility and determine the extent, if any, to which a change is required in the Contract Documents to reflect and document the consequences of the existence or location of the Underground Facility. During such time, Contractor shall be responsible for the safety and protection of such Underground Facility. 2. If Engineer concludes that a change in the Contract Documents is required, a Work Change Directive or a Change Order will be issued to reflect and document such consequences. An equitable adjustment shall be made in the Contract Price or Contract Times, or both, to the extent that they are attributable to the existence or location of any Underground Facility that was not shown or indicated or not shown or indicated with reasonable accuracy in the Contract Documents and that Contractor did not know of and could not reasonably have been expected to be aware of or to have anticipated. If Owner and Contractor are unable to agree on entitlement to or on the amount or extent, if any, of any such adjustment in Contract Price or Contract Times, Owner or Contractor may make a Claim therefor as provided in Paragraph 10.05. 4.05 Reference Points A. Owner shall provide engineering surveys to establish reference points for construction which in Engineer’s judgment are necessary to enable Contractor to proceed with the Work. Contractor shall be responsible for laying out the Work, shall protect and preserve the established reference points and property monuments, and shall make no changes or relocations without the prior written approval of Owner. Contractor shall report to Engineer whenever any reference point or property monument is lost or destroyed or requires relocation because of necessary changes in grades or locations, and shall be responsible for the accurate replacement or relocation of such reference points or property monuments by professionally qualified personnel. 4.06 Hazardous Environmental Condition at Site A. Reports and Drawings: Reference is made to the Supplementary Conditions for the identification of those reports and drawings relating to a Hazardous Environmental Condition identified at the Site, if any,
that have been utilized by the Engineer in the preparation of the Contract Documents. B. Limited Reliance by Contractor on Technical Data Authorized: Contractor may rely upon the general accuracy of the “technical data” contained in such reports and drawings, but such reports and drawings are not Contract Documents. Such “technical data” is identified in the Supplementary Conditions. Except for such reliance on such “technical data,” Contractor may not rely upon or make any claim against Owner or Engineer, or any of their Related Entities with respect to: 1. the completeness of such reports and drawings for Contractor’s purposes, including, but not limited to, any aspects of the means, methods, techniques, sequences and procedures of construction to be employed by Contractor and safety precautions and programs incident thereto; or 2. other data, interpretations, opinions and information contained in such reports or shown or indicated in such drawings; or 3. any Contractor interpretation of or conclusion drawn from any “technical data” or any such other data, interpretations, opinions or information. C. Contractor shall not be responsible for any Hazardous Environmental Condition uncovered or re‐vealed at the Site which was not shown or indicated in Drawings or Specifications or identified in the Contract Documents to be within the scope of the Work. Contractor shall be responsible for a Hazardous Environmental Condition created with any materials brought to the Site by Contractor, Subcontractors, Suppliers, or anyone else for whom Contractor is responsible. D. If Contractor encounters a Hazardous Environmental Condition or if Contractor or anyone for whom Contractor is responsible creates a Hazardous Environmental Condition, Contractor shall immediately: (i) secure or otherwise isolate such condition; (ii) stop all Work in connection with such condition and in any area affected thereby (except in an emergency as required by Paragraph 6.16.A); and (iii) notify Owner and Engineer (and promptly thereafter confirm such notice in writing). Owner shall promptly consult with Engineer concerning the necessity for Owner to retain a qualified expert to evaluate such condition or take corrective action, if any. E. Contractor shall not be required to resume Work in connection with such condition or in any affected area until after Owner has obtained any required permits related thereto and delivered to Contractor written notice: (i) specifying that such
15‐175 General Conditions ‐13
condition and any affected area is or has been rendered safe for the resumption of Work; or (ii) specifying any special conditions under which such Work may be re‐sumed safely. If Owner and Contractor cannot agree as to entitlement to or on the amount or extent, if any, of any adjustment in Contract Price or Contract Times, or both, as a result of such Work stoppage or such special conditions under which Work is agreed to be resumed by Contractor, either party may make a Claim therefor as provided in Paragraph 10.05. F. If after receipt of such written notice Contractor does not agree to resume such Work based on a reasonable belief it is unsafe, or does not agree to resume such Work under such special conditions, then Owner may order the portion of the Work that is in the area affected by such condition to be deleted from the Work. If Owner and Contractor cannot agree as to entitlement to or on the amount or extent, if any, of an adjustment in Contract Price or Contract Times as a result of deleting such portion of the Work, then either party may make a Claim therefor as provided in Paragraph 10.05. Owner may have such deleted portion of the Work performed by Owner’s own forces or others in accordance with Article 7. G. To the fullest extent permitted by Laws and Regulations, Owner shall indemnify and hold harmless Contractor, Subcontractors, and Engineer, and the officers, directors, partners, employees, agents, consultants, and subcontractors of each and any of them from and against all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to a Hazardous Environmental Condition, provided that such Hazardous Environmental Condition: (i) was not shown or indicated in the Drawings or Specifications or identified in the Contract Documents to be included within the scope of the Work, and (ii) was not created by Contractor or by anyone for whom Contractor is responsible. Nothing in this Paragraph 4.06. G shall obligate Owner to indemnify any individual or entity from and against the conse‐quences of that individual’s or entity’s own negligence. H. To the fullest extent permitted by Laws and Regulations, Contractor shall indemnify and hold harmless Owner and Engineer, and the officers, directors, partners, employees, agents, consultants, and subcontractors of each and any of them from and against all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to a Hazardous Environmental Condition created by Contractor or by anyone for whom Contractor
is responsible. Nothing in this Paragraph 4.06.H shall obligate Contractor to indemnify any individual or entity from and against the consequences of that individual’s or entity’s own negligence. I. The provisions of Paragraphs 4.02, 4.03, and 4.04 do not apply to a Hazardous Environmental Condition uncovered or revealed at the Site. ARTICLE 5 ‐ BONDS AND INSURANCE

Any insured loss under the policies of insurance required by Paragraph 5.06 will be adjusted with Owner and made payable to Owner as fiduciary for the insureds, as their interests may appear, subject to the requirements of any applicable mortgage clause and of Paragraph 5.08.B. Owner shall deposit in a separate account any money so received and shall distribute it in accordance with such agreement as the parties in interest may reach. If no other special agreement is reached, the damaged Work shall be repaired or re‐placed, the moneys so received applied on account thereof, and the Work and the cost thereof covered by an appropriate Change Order . B. Owner as fiduciary shall have power to adjust and settle any loss with the insurers unless one of the parties in interest shall object in writing within 15 days after the occurrence of loss to Owner’s exercise of this power. If such objection be made, Owner as fiduciary shall make settlement with the insurers in accordance with such agreement as the parties in interest may reach. If no such agreement among the parties in interest is reached, Owner as fiduciary shall adjust and settle the loss with the insurers and, if required in writing by any party in interest, Owner as fiduciary shall give bond for the proper performance of such duties. 5.09 Acceptance of Bonds and Insurance; Option to Replace A.

Owner and Contractor shall each provide to the other such additional information in respect of insurance provided as the other may reasonably request. If either party does not purchase or maintain all of the bonds and insurance required of such party by the Contract Documents, such party shall notify the other party in writing of such failure to purchase
15‐175 General Conditions ‐17
prior to the start of the Work, or of such failure to maintain prior to any change in the required coverage. Without prejudice to any other right or remedy, the other party may elect to obtain equivalent bonds or insurance to protect such other party's interests at the expense of the party who was required to provide such coverage, and a Change Order shall be issued to adjust the Contract Price accordingly. 5.10 Partial Utilization, Acknowledgment of Property Insurer A. If Owner finds it necessary to occupy or use a portion or portions of the Work prior to Substantial Completion of all the Work as provided in Paragraph 14.05, no such use or occupancy shall commence before the insurers providing the property insurance pursuant to Paragraph 5.06 have acknowledged notice thereof and in writing effected any changes in coverage necessitated thereby. The insurers providing the property insurance shall consent by endorsement on the policy or policies, but the property insurance shall not be canceled or permitted to lapse on account of any such partial use or occupancy. ARTICLE 6 ‐ CONTRACTOR’S RESPONSIBILITIES
6.01 Supervision and Superintendence A. Contractor shall supervise, inspect, and direct the Work competently and efficiently, devoting such attention thereto and applying such skills and expertise as may be necessary to perform the Work in accordance with the Contract Documents. Contractor shall be solely responsible for the means, methods, techniques, sequences, and procedures of construction. Contractor shall not be responsible for the negligence of Owner or Engineer in the design or specification of a specific means, method, technique, sequence, or procedure of construction which is shown or indicated in and expressly required by the Contract Documents. B. At all times during the progress of the Work, Contractor shall assign a competent resident superin‐tendent who shall not be replaced without written notice to Owner and Engineer except under extraordinary circumstances. The superintendent will be Contractor’s representative at the Site and shall have authority to act on behalf of Contractor. All communications given to or received from the superintendent shall be binding on Contractor.
6.02 Labor; Working Hours A. Contractor shall provide competent, suitably qualified personnel to survey and lay out the Work and perform construction as required by the Contract Docu‐ments. Contractor shall at all times maintain good disci‐pline and order at the Site. B. Except as otherwise required for the safety or protection of persons or the Work or property at the Site or adjacent thereto, and except as otherwise stated in the Contract Documents, all Work at the Site shall be performed during regular working hours. Contractor will not permit the performance of Work on a Saturday, Sunday, or any legal holiday without Owner’s written consent (which will not be unreasonably withheld) given after prior written notice to Engineer. 6.03 Services, Materials, and Equipment A. Unless otherwise specified in the Contract Documents, Contractor shall provide and assume full responsibility for all services, materials, equipment, labor, transportation, construction equipment and machinery, tools, appliances, fuel, power, light, heat, telephone, water, sanitary facilities, temporary facilities, and all other facilities and incidentals necessary for the performance, testing, start‐up, and completion of the Work. B. All materials and equipment incorporated into the Work shall be as specified or, if not specified, shall be of good quality and new, except as otherwise provided in the Contract Documents.

Such adjust‐
15‐175 General Conditions ‐18
ments will comply with any provisions of the General Re‐quirements applicable thereto. 2. Proposed adjustments in the Progress Schedule that will change the Contract Times shall be submitted in accordance with the requirements of Article 12. Adjustments in Contract Times may only be made by a Change Order. 6.05 Substitutes and “Or‐Equals” A. Whenever an item of material or equipment is specified or described in the Contract Documents by using the name of a proprietary item or the name of a particular Supplier, the specification or description is intended to establish the type, function, appearance, and quality required. Unless the specification or description contains or is followed by words reading that no like, equivalent, or “or‐equal” item or no substitution is permitted, other items of material or equipment or material or equipment of other Suppliers may be submitted to Engineer for review under the circum‐stances described below. 1. “Or‐Equal” Items: If in Engineer’s sole discre‐tion an item of material or equipment proposed by Contractor is functionally equal to that named and sufficiently similar so that no change in related Work will be required, it may be considered by Engineer as an “or‐equal” item, in which case review and approval of the proposed item may, in Engineer’s sole discretion, be accomplished without compliance with some or all of the requirements for approval of proposed substitute items. For the purposes of this Paragraph 6.05.A.1, a proposed item of material or equipment will be considered functionally equal to an item so named if:
a. in the exercise of reasonable judgment Engineer determines that:
1) it is at least equal in materials of construction, quality, durability, appearance, strength, and design characteristics; 2) it will reliably perform at least equally well the function and achieve the results imposed by the design concept of the completed Project as a functioning whole, 3) it has a proven record of performance and availability of responsive service; and
b. Contractor certifies that, if approved and incorporated into the Work:
1) there will be no increase in cost to the Owner or increase in Contract Times, and 2) it will conform substantially to the detailed requirements of the item named in the Contract Documents.
2. Substitute Items
a. If in Engineer’s sole discretion an item of material or equipment proposed by Contractor does not qualify as an “or‐equal” item under Paragraph 6.05.A.1, it will be considered a proposed substitute item. b. Contractor shall submit sufficient information as provided below to allow Engineer to determine that the item of material or equipment proposed is essentially equivalent to that named and an acceptable substitute therefor. Requests for review of proposed substitute items of material or equipment will not be accepted by Engineer from anyone other than Contractor. c. The requirements for review by Engineer will be as set forth in Paragraph 6.05.A.2.d, as supplemented in the General Requirements and as Engineer may decide is appropriate under the circumstances. d. Contractor shall make written application to Engineer for review of a proposed substitute item of material or equipment that Contractor seeks to furnish or use. The application:
1) shall certify that the proposed substitute item will:
a) perform adequately the functions and achieve the results called for by the general design, b) be similar in substance to that specified, and c) be suited to the same use as that specified;
2) will state:
a) the extent, if any, to which the use of the proposed substitute item will preju‐dice Contractor’s achievement of Substantial Completion on time;
15‐175 General Conditions ‐19
b) whether or not use of the proposed substitute item in the Work will require a change in any of the Contract Docu‐ments (or in the provisions of any other direct contract with Owner for other work on the Project) to adapt the de‐sign to the proposed substitute item; and c) whether or not incorporation or use of the proposed substitute item in con‐nection with the Work is subject to payment of any license fee or royalty;
3) will identify:
a) all variations of the proposed substitute item from that specified , and b) available engineering, sales, maintenance, repair, and replacement services;
4) and shall contain an itemized esti‐mate of all costs or credits that will result directly or indirectly from use of such substitute item, including costs of redesign and claims of other contractors affected by any resulting change,
B. Substitute Construction Methods or Proce‐dures: If a specific means, method, technique, sequence, or procedure of construction is expressly required by the Contract Documents, Contractor may furnish or utilize a substitute means, method, technique, sequence, or procedure of construction approved by Engineer. Contractor shall submit sufficient information to allow Engineer, in Engineer’s sole discretion, to determine that the substitute proposed is equivalent to that expressly called for by the Contract Documents. The requirements for review by Engineer will be similar to those provided in Paragraph 6.05.A.2. C. Engineer’s Evaluation: Engineer will be allowed a reasonable time within which to evaluate each proposal or submittal made pursuant to Paragraphs 6.05.A and 6.05.B. Engineer may require Contractor to furnish additional data about the proposed substitute item. Engineer will be the sole judge of acceptability. No “or equal” or substitute will be ordered, installed or utilized until Engineer’s review is complete, which will be evidenced by either a Change Order for a substitute or an approved Shop Drawing for an “or equal.” Engineer will advise Contractor in writing of any negative determination.
D. Special Guarantee: Owner may require Contractor to furnish at Contractor’s expense a special performance guarantee or other surety with respect to any substitute. E. Engineer’s Cost Reimbursement: Engineer will record Engineer’s costs in evaluating a substitute proposed or submitted by Contractor pursuant to Paragraphs 6.05.A.2 and 6.05.B Whether or not Engineer approves a substitute item so proposed or submitted by Contractor, Contractor shall reimburse Owner for the charges of Engineer for evaluating each such proposed substitute. Contractor shall also reimburse Owner for the charges of Engineer for making changes in the Contract Documents (or in the provisions of any other direct contract with Owner) resulting from the acceptance of each proposed substitute. F. Contractor’s Expense: Contractor shall provide all data in support of any proposed substitute or “or‐equal” at Contractor’s expense. 6.06 Concerning Subcontractors, Suppliers, and Others A. Contractor shall not employ any Subcon‐tractor, Supplier, or other individual or entity (including those acceptable to Owner as indicated in Paragraph 6.06.B), whether initially or as a replacement, against whom Owner may have reasonable objection. Contractor shall not be required to employ any Subcontractor, Supplier, or other individual or entity to furnish or perform any of the Work against whom Contractor has reasonable objection. B. If the Supplementary Conditions require the identity of certain Subcontractors, Suppliers, or other individuals or entities to be submitted to Owner in advance for acceptance by Owner by a specified date prior to the Effective Date of the Agreement, and if Contractor has submitted a list thereof in accordance with the Supplementary Conditions, Owner’s acceptance (either in writing or by failing to make written objection thereto by the date indicated for acceptance or objection in the Bidding Documents or the Contract Documents) of any such Subcontractor, Supplier, or other individual or entity so identified may be revoked on the basis of reasonable objection after due investigation. Contractor shall submit an acceptable replacement for the rejected Subcontractor, Supplier, or other individual or entity, and the Contract Price will be adjusted by the difference in the cost occasioned by such replacement, and an appropriate Change Order will be issued. No acceptance by Owner of any such Subcontractor, Supplier, or other individual or entity, whether initially or as a replacement, shall constitute a waiver of any right of Owner or Engineer to reject defective Work.
15‐175 General Conditions ‐20
C. Contractor shall be fully responsible to Owner and Engineer for all acts and omissions of the Subcontractors, Suppliers, and other individuals or entities performing or furnishing any of the Work just as Contractor is responsible for Contractor’s own acts and omissions. Nothing in the Contract Documents: 1. shall create for the benefit of any such Subcontractor, Supplier, or other individual or entity any contractual relationship between Owner or Engineer and any such Subcontractor, Supplier or other individual or entity, nor 2. shall it create any obligation on the part of Owner or Engineer to pay or to see to the payment of any moneys due any such Subcontractor, Supplier, or other individual or entity except as may otherwise be re‐quired by Laws and Regulations. D. Contractor shall be solely responsible for scheduling and coordinating the Work of Subcontractors, Suppliers, and other individuals or entities performing or furnishing any of the Work under a direct or indirect contract with Contractor. E. Contractor shall require all Subcontractors, Suppliers, and such other individuals or entities per‐forming or furnishing any of the Work to communicate with Engineer through Contractor. F. The divisions and sections of the Specifica‐tions and the identifications of any Drawings shall not control Contractor in dividing the Work among Subcon‐tractors or Suppliers or delineating the Work to be performed by any specific trade. G. All Work performed for Contractor by a Subcontractor or Supplier will be pursuant to an appro‐priate agreement between Contractor and the Subcontractor or Supplier which specifically binds the Subcontractor or Supplier to the applicable terms and conditions of the Contract Documents for the benefit of Owner and Engineer.

Work under Paragraph 13.09, or (iii) agreed to by the parties; 2. changes in the Contract Price or Contract Times which are agreed to by the parties, including any undisputed sum or amount of time for Work actually performed in accordance with a Work Change Directive; and 3. changes in the Contract Price or Contract Times which embody the substance of any written decision rendered by Engineer pursuant to Paragraph 10.05; provided that, in lieu of executing any such Change Order, an appeal may be taken from any such decision in accordance with the provisions of the Contract Documents and applicable Laws and Regula‐tions, but during any such appeal, Contractor shall carry on the Work and adhere to the Progress Schedule as provided in Paragraph 6.18.A. 10.04 Notification to Surety A. If notice of any change affecting the general scope of the Work or the provisions of the Contract Documents (including, but not limited to, Contract Price or Contract Times) is required by the provisions of any bond to be given to a surety, the giving of any such notice will be Contractor’s responsibility. The amount of each applicable bond will be adjusted to reflect the effect of any such change. 10.05 Claims A. Engineer’s Decision Required: All Claims, except those waived pursuant to Paragraph 14.09, shall be referred to the Engineer for decision. A decision by Engineer shall be required as a condition precedent to any exercise by Owner or Contractor of any rights or remedies either may otherwise have under the Contract Documents or by Laws and Regulations in respect of such Claims. B. Notice: Written notice stating the general nature of each Claim, shall be delivered by the claimant to Engineer and the other party to the Contract promptly (but in no event later than 30 days) after the start of the event giving rise thereto. The responsibility to substantiate a Claim shall rest with the party making the Claim. Notice of the amount or extent of the Claim, with supporting data shall be delivered to the Engineer and the other party to the Contract within 60 days after the start of such event (unless Engineer allows additional time for claimant to submit additional or more accurate data in support of such Claim). A Claim for an adjustment in Contract Price shall be prepared in accordance with the provisions of Paragraph 12.01.B. A Claim for an adjustment in Contract Time shall be prepared in
accordance with the provisions of Paragraph 12.02.B. Each Claim shall be accompanied by claimant's written statement that the adjustment claimed is the entire adjustment to which the claimant believes it is entitled as a result of said event. The opposing party shall submit any response to Engineer and the claimant within 30 days after receipt of the claimant’s last submittal (unless Engineer allows additional time). C. Engineer’s Action: Engineer will review each Claim and, within 30 days after receipt of the last submittal of the claimant or the last submittal of the opposing party, if any, take one of the following actions in writing: 1. deny the Claim in whole or in part, 2. approve the Claim, or 3. notify the parties that the Engineer is unable to resolve the Claim if, in the Engineer’s sole discretion, it would be inappropriate for the Engineer to do so. For purposes of further resolution of the Claim, such notice shall be deemed a denial. D. In the event that Engineer does not take action on a Claim within said 30 days, the Claim shall be deemed denied. E. Engineer’s written action under Paragraph 10.05.C or denial pursuant to Paragraphs 10.05.C.3 or 10.05.D will be final and binding upon Owner and Contractor, unless Owner or Contractor invoke the dispute resolution procedure set forth in Article 16 within 30 days of such action or denial. F. No Claim for an adjustment in Contract Price or Contract Times will be valid if not submitted in accordance with this Paragraph 10.05. ARTICLE 11 ‐ COST OF THE WORK; ALLOWANCES; UNIT PRICE WORK
11.01 Cost of the Work A. Costs Included: The term Cost of the Work means the sum of all costs, except those excluded in Paragraph 11.01.B, necessarily incurred and paid by Contractor in the proper performance of the Work. When the value of any Work covered by a Change Order or when a Claim for an adjustment in Contract Price is determined on the basis of Cost of the Work, the costs to be reimbursed to Contractor will be only those additional or incremental costs required because of the change in the Work or because of the event giving rise to the Claim.

Cost of all materials and equipment furnished and incorporated in the Work, including costs of transportation and storage thereof, and Suppliers’ field services required in connection therewith. All cash discounts shall accrue to Contractor unless Owner deposits funds with Contractor with which to make pay‐ments, in which case the cash discounts shall accrue to Owner. All trade discounts, rebates and refunds and returns from sale of surplus materials and equipment shall accrue to Owner, and Contractor shall make provisions so that they may be obtained. 3.

Other overhead or general expense costs of any kind and the costs of any item not specifically and expressly included in Paragraphs 11.01.A and 11.01.B. C. Contractor’s Fee: When all the Work is performed on the basis of cost‐plus, Contractor’s fee shall be determined as set forth in the Agreement. When the value of any Work covered by a Change Order or when a Claim for an adjustment in Contract Price is determined on the basis of Cost of the Work,
Contractor’s fee shall be determined as set forth in Paragraph 12.01.C. D. Documentation: Whenever the Cost of the Work for any purpose is to be determined pursuant to Paragraphs 11.01.A and 11.01.B, Contractor will establish and maintain records thereof in accordance with generally accepted accounting practices and submit in a form acceptable to Engineer an itemized cost breakdown together with supporting data. 11.02 Allowances A. It is understood that Contractor has included in the Contract Price all allowances so named in the Contract Documents and shall cause the Work so covered to be performed for such sums and by such persons or entities as may be acceptable to Owner and Engineer. B. Cash Allowances 1. Contractor agrees that:
a. the cash allowances include the cost to Contractor (less any applicable trade discounts) of materials and equipment required by the allowances to be delivered at the Site, and all applicable taxes; and b. Contractor’s costs for unloading and handling on the Site, labor, installation , overhead, profit, and other expenses contemplated for the cash allowances have been included in the Contract Price and not in the allowances, and no demand for additional payment on account of any of the foregoing will be valid.
C. Contingency Allowance
1. Contractor agrees that a contingency allowance, if any, is for the sole use of Owner to cover unanticipated costs. D. Prior to final payment, an appropriate Change Order will be issued as recommended by Engineer to reflect actual amounts due Contractor on account of Work covered by allowances, and the Contract Price shall be correspondingly adjusted. 11.03 Unit Price Work A. Where the Contract Documents provide that all or part of the Work is to be Unit Price Work, initially the Contract Price will be deemed to include for all Unit Price Work an amount equal to the sum of the unit price for each separately identified item of Unit Price Work
15‐175 General Conditions ‐32
times the estimated quantity of each item as indicated in the Agreement. B. The estimated quantities of items of Unit Price Work are not guaranteed and are solely for the purpose of comparison of Bids and determining an initial Contract Price. Determinations of the actual quantities and classifications of Unit Price Work performed by Contractor will be made by Engineer subject to the provisions of Paragraph 9.07. C. Each unit price will be deemed to include an amount considered by Contractor to be adequate to cover Contractor’s overhead and profit for each separately identified item. D. Owner or Contractor may make a Claim for an adjustment in the Contract Price in accordance with Paragraph 10.05 if: 1. the quantity of any item of Unit Price Work performed by Contractor differs materially and signifi‐cantly from the estimated quantity of such item indicated in the Agreement; and 2. there is no corresponding adjustment with respect any other item of Work; and 3. Contractor believes that Contractor is entitled to an increase in Contract Price as a result of having incurred additional expense or Owner believes that Owner is entitled to a decrease in Contract Price and the parties are unable to agree as to the amount of any such increase or decrease. ARTICLE 12 ‐ CHANGE OF CONTRACT PRICE; CHANGE OF CONTRACT TIMES
12.01 Change of Contract Price A. The Contract Price may only be changed by a Change Order. Any Claim for an adjustment in the Contract Price shall be based on written notice submitted by the party making the Claim to the Engineer and the other party to the Contract in accordance with the provisions of Paragraph 10.05. B. The value of any Work covered by a Change Order or of any Claim for an adjustment in the Contract Price will be determined as follows: 1. where the Work involved is covered by unit prices contained in the Contract Documents, by applica‐tion of such unit prices to the quantities of the items
involved (subject to the provisions of Paragraph 11.03); or 2. where the Work involved is not covered by unit prices contained in the Contract Documents, by a mutually agreed lump sum (which may include an allowance for overhead and profit not necessarily in accordance with Paragraph 12.01.C.2); or 3. where the Work involved is not covered by unit prices contained in the Contract Documents and agreement to a lump sum is not reached under Paragraph 12.01.B.2, on the basis of the Cost of the Work (determined as provided in Paragraph 11.01) plus a Contractor’s fee for overhead and profit (determined as provided in Paragraph 12.01.C). C. Contractor’s Fee: The Contractor’s fee for overhead and profit shall be determined as follows: 1. a mutually acceptable fixed fee; or 2. if a fixed fee is not agreed upon, then a fee based on the following percentages of the various portions of the Cost of the Work:
a. for costs incurred under Paragraphs 11.01.A.1 and 11.01.A.2, the Contractor’s fee shall be 15 percent; b. for costs incurred under Paragraph 11.01.A.3, the Contractor’s fee shall be five percent; c. where one or more tiers of subcontracts are on the basis of Cost of the Work plus a fee and no fixed fee is agreed upon, the intent of Paragraph 12.01.C.2.a is that the Subcontractor who actually performs the Work, at whatever tier, will be paid a fee of 15 percent of the costs incurred by such Subcontractor under Paragraphs 11.01.A.1 and 11.01.A.2 and that any higher tier Subcontractor and Contractor will each be paid a fee of five percent of the amount paid to the next lower tier Subcon‐tractor; d. no fee shall be payable on the basis of costs itemized under Paragraphs 11.01.A.4, 11.01.A.5, and 11.01.B; e. the amount of credit to be allowed by Contractor to Owner for any change which results in a net decrease in cost will be the amount of the actual net decrease in cost plus a deduction in Contractor’s fee by an amount equal to five percent of such net decrease; and
15‐175 General Conditions ‐33
f. when both additions and credits are involved in any one change, the adjustment in Contractor’s fee shall be computed on the basis of the net change in accordance with Paragraphs 12.01.C.2.a through 12.01.C.2.e, inclusive.
12.02 Change of Contract Times A. The Contract Times may only be changed by a Change Order. Any Claim for an adjustment in the Contract Times shall be based on written notice submitted by the party making the Claim to the Engineer and the other party to the Contract in accordance with the provisions of Paragraph 10.05. B. Any adjustment of the Contract Times covered by a Change Order or any Claim for an adjustment in the Contract Times will be determined in accordance with the provisions of this Article 12. 12.03 Delays A. Where Contractor is prevented from completing any part of the Work within the Contract Times due to delay beyond the control of Contractor, the Contract Times will be extended in an amount equal to the time lost due to such delay if a Claim is made therefor as provided in Paragraph 12.02.A. Delays beyond the control of Contractor shall include, but not be limited to, acts or neglect by Owner, acts or neglect of utility owners or other contractors performing other work as contemplated by Article 7, fires, floods, epidemics, abnormal weather conditions, or acts of God. B. If Owner, Engineer, or other contractors or utility owners performing other work for Owner as contemplated by Article 7, or anyone for whom Owner is responsible, delays, disrupts, or interferes with the performance or progress of the Work, then Contractor shall be entitled to an equitable adjustment in the Contract Price or the Contract Times , or both. Contractor’s entitlement to an adjustment of the Contract Times is conditioned on such adjustment being essential to Contractor’s ability to complete the Work within the Contract Times. C If Contractor is delayed in the performance or progress of the Work by fire, flood, epidemic, abnormal weather conditions, acts of God, acts or failures to act of utility owners not under the control of Owner, or other causes not the fault of and beyond control of Owner and Contractor, then Contractor shall be entitled to an equitable adjustment in Contract Times, if such adjustment is essential to Contractor’s ability to complete the Work within the Contract Times. Such an adjustment shall be Contractor’s sole and exclusive
remedy for the delays described in this Paragraph 12.03.C. D. Owner, Engineer and the Related Entities of each of them shall not be liable to Contractor for any claims, costs, losses, or damages (including but not limited to all fees and charges of Engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by Contractor on or in connection with any other project or anticipated project. E. Contractor shall not be entitled to an adjustment in Contract Price or Contract Times for delays within the control of Contractor. Delays attributable to and within the control of a Subcontractor or Supplier shall be deemed to be delays within the control of Contractor. ARTICLE 13 ‐ TESTS AND INSPECTIONS; CORRECTION, REMOVAL OR ACCEPTANCE OF DEFECTIVE WORK
13.01 Notice of Defects A. Prompt notice of all defective Work of which Owner or Engineer has actual knowledge will be given to Contractor. All defective Work may be rejected, corrected, or accepted as provided in this Article 13. 13.02 Access to Work A. Owner, Engineer, their consultants and other representatives and personnel of Owner, independent testing laboratories, and governmental agencies with jurisdictional interests will have access to the Site and the Work at reasonable times for their observation, inspecting, and testing. Contractor shall provide them proper and safe conditions for such access and advise them of Contractor’s Site safety procedures and programs so that they may comply therewith as applicable. 13.03 Tests and Inspections A. Contractor shall give Engineer timely notice of readiness of the Work for all required inspections, tests, or approvals and shall cooperate with inspection and testing personnel to facilitate required inspections or tests. B. Owner shall employ and pay for the services of an independent testing laboratory to perform all inspections, tests, or approvals required by the Contract Documents except:
15‐175 General Conditions ‐34
1. for inspections, tests, or approvals covered by Paragraphs 13.03.C and 13.03.D below; 2. that costs incurred in connection with tests or inspections conducted pursuant to Paragraph 13.04.B shall be paid as provided in said Paragraph 13.04.C; and 3. as otherwise specifically provided in the Con‐tract Documents. C. If Laws or Regulations of any public body having jurisdiction require any Work (or part thereof) specifically to be inspected, tested, or approved by an employee or other representative of such public body, Contractor shall assume full responsibility for arranging and obtaining such inspections, tests, or approvals, pay all costs in connection therewith, and furnish Engineer the required certificates of inspection or approval. D. Contractor shall be responsible for arranging and obtaining and shall pay all costs in connection with any inspections, tests, or approvals required for Owner’s and Engineer’s acceptance of materials or equipment to be incorporated in the Work; or acceptance of materials, mix designs, or equipment submitted for approval prior to Contractor’s purchase thereof for incorporation in the Work. Such inspections, tests, or approvals shall be performed by organizations acceptable to Owner and Engineer. E. If any Work (or the work of others) that is to be inspected, tested, or approved is covered by Contractor without written concurrence of Engineer, it must, if requested by Engineer, be uncovered for observation. F. Uncovering Work as provided in Paragraph 13.03.E shall be at Contractor’s expense unless Contractor has given Engineer timely notice of Contractor’s intention to cover the same and Engineer has not acted with reasonable promptness in response to such notice. 13.04 Uncovering Work A. If any Work is covered contrary to the written request of Engineer, it must, if requested by Engineer, be uncovered for Engineer’s observation and replaced at Contractor’s expense. B. If Engineer considers it necessary or advisable that covered Work be observed by Engineer or inspected or tested by others, Contractor, at Engineer’s request, shall uncover, expose, or otherwise make available for observation, inspection, or testing as Engineer may require, that portion of the Work in question, furnishing all necessary labor, material, and equipment.
C. If it is found that the uncovered Work is defective, Contractor shall pay all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such uncovering, exposure, observation, inspection, and testing, and of satisfactory replacement or reconstruction (including but not limited to all costs of repair or replacement of work of others); and Owner shall be entitled to an appropriate decrease in the Contract Price. If the parties are unable to agree as to the amount thereof, Owner may make a Claim therefor as provided in Paragraph 10.05. D. If, the uncovered Work is not found to be defective, Contractor shall be allowed an increase in the Contract Price or an extension of the Contract Times, or both, directly attributable to such uncovering, exposure, observation, inspection, testing, replacement, and reconstruction. If the parties are unable to agree as to the amount or extent thereof, Contractor may make a Claim therefor as provided in Paragraph 10.05. 13.05 Owner May Stop the Work A. If the Work is defective, or Contractor fails to supply sufficient skilled workers or suitable materials or equipment, or fails to perform the Work in such a way that the completed Work will conform to the Contract Documents, Owner may order Contractor to stop the Work, or any portion thereof, until the cause for such order has been eliminated; however, this right of Owner to stop the Work shall not give rise to any duty on the part of Owner to exercise this right for the benefit of Contractor, any Subcontractor, any Supplier, any other individual or entity, or any surety for, or employee or agent of any of them. 13.06 Correction or Removal of Defective Work A. Promptly after receipt of notice, Contractor shall correct all defective Work, whether or not fabricated, installed, or completed, or, if the Work has been rejected by Engineer, remove it from the Project and replace it with Work that is not defective. Contractor shall pay all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or removal (including but not limited to all costs of repair or replacement of work of others). B. When correcting defective Work under the terms of this Paragraph 13.06 or Paragraph 13.07,
15‐175 General Conditions ‐35
Contractor shall take no action that would void or otherwise impair Owner’s special warranty and guarantee, if any, on said Work. 13.07 Correction Period A. If within one year after the date of Substantial Completion (or such longer period of time as may be prescribed by the terms of any applicable special guarantee required by the Contract Documents) or by any specific provision of the Contract Documents, any Work is found to be defective, or if the repair of any damages to the land or areas made available for Contractor’s use by Owner or permitted by Laws and Regulations as contemplated in Paragraph 6.11.A is found to be defective, Contractor shall promptly, without cost to Owner and in accordance with Owner’s written instructions: 1. repair such defective land or areas; or 2. correct such defective Work; or 3. if the defective Work has been rejected by Owner, remove it from the Project and replace it with Work that is not defective, and 4. satisfactorily correct or repair or remove and replace any damage to other Work, to the work of others or other land or areas resulting therefrom. B. If Contractor does not promptly comply with the terms of Owner’s written instructions, or in an emergency where delay would cause serious risk of loss or damage, Owner may have the defective Work corrected or repaired or may have the rejected Work re‐moved and replaced. All claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or repair or such removal and replacement (including but not limited to all costs of repair or replace‐ment of work of others) will be paid by Contractor. C. In special circumstances where a particular item of equipment is placed in continuous service before Substantial Completion of all the Work, the correction period for that item may start to run from an earlier date if so provided in the Specifications . D. Where defective Work (and damage to other Work resulting therefrom) has been corrected or removed and replaced under this Paragraph 13.07, the correction period hereunder with respect to such Work will be extended for an additional period of one year
after such correction or removal and replacement has been satisfactorily completed. E. Contractor’s obligations under this Paragraph 13.07 are in addition to any other obligation or warranty. The provisions of this Paragraph 13.07 shall not be construed as a substitute for or a waiver of the provisions of any applicable statute of limitation or repose. 13.08 Acceptance of Defective Work A. If, instead of requiring correction or removal and replacement of defective Work, Owner (and, prior to Engineer’s recommendation of final payment, Engineer) prefers to accept it, Owner may do so. Contractor shall pay all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) attributable to Owner’s evaluation of and determination to accept such defective Work (such costs to be approved by Engineer as to reasonableness) and the diminished value of the Work to the extent not otherwise paid by Contractor pursuant to this sentence. If any such acceptance occurs prior to Engineer’s recom‐mendation of final payment, a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work, and Owner shall be entitled to an appropriate decrease in the Contract Price, reflecting the diminished value of Work so accepted. If the parties are unable to agree as to the amount thereof, Owner may make a Claim therefor as provided in Paragraph 10.05. If the acceptance occurs after such recommendation, an appropriate amount will be paid by Contractor to Owner. 13.09 Owner May Correct Defective Work A. If Contractor fails within a reasonable time after written notice from Engineer to correct defective Work or to remove and replace rejected Work as required by Engineer in accordance with Paragraph 13.06.A, or if Contractor fails to perform the Work in accordance with the Contract Documents, or if Contractor fails to comply with any other provision of the Contract Documents, Owner may, after seven days written notice to Contractor, correct or remedy any such deficiency. B. In exercising the rights and remedies under this Paragraph 13.09, Owner shall proceed expeditiously. In connection with such corrective or remedial action, Owner may exclude Contractor from all or part of the Site, take possession of all or part of the Work and suspend Contractor’s services related thereto, take possession of Contractor’s tools, appliances, construction equipment and machinery at the Site, and incorporate in
15‐175 General Conditions ‐36
the Work all materials and equipment stored at the Site or for which Owner has paid Contractor but which are stored elsewhere. Contractor shall allow Owner, Owner’s representatives, agents and employees, Owner’s other contractors, and Engineer and Engineer’s consultants access to the Site to enable Owner to exercise the rights and remedies under this Paragraph. C. All claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) incurred or sustained by Owner in exercising the rights and remedies under this Paragraph 13.09 will be charged against Contractor, and a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work; and Owner shall be entitled to an appropriate decrease in the Contract Price. If the parties are unable to agree as to the amount of the adjustment, Owner may make a Claim therefor as provided in Paragraph 10.05. Such claims, costs, losses and damages will include but not be limited to all costs of repair, or replacement of work of others destroyed or damaged by correction, removal, or replacement of Contractor’s defective Work. D. Contractor shall not be allowed an extension of the Contract Times because of any delay in the performance of the Work attributable to the exercise by Owner of Owner’s rights and remedies under this Paragraph 13.09. ARTICLE 14 ‐ PAYMENTS TO CONTRACTOR AND COMPLETION
14.01 Schedule of Values A. The Schedule of Values established as provid‐ed in Paragraph 2.07.A will serve as the basis for progress payments and will be incorporated into a form of Application for Payment acceptable to Engineer. Progress payments on account of Unit Price Work will be based on the number of units completed. 14.02 Progress Payments A. Applications for Payments 1. At least 20 days before the date established in the Agreement for each progress payment (but not more often than once a month), Contractor shall submit to Engineer for review an Application for Payment filled out and signed by Contractor covering the Work completed as of the date of the Application and accompanied by such supporting documentation as is required by the
Contract Documents. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the Site or at another location agreed to in writing, the Application for Payment shall also be accompanied by a bill of sale, invoice, or other documentation warranting that Owner has received the materials and equipment free and clear of all Liens and evidence that the materials and equipment are covered by appropriate property insurance or other arrangements to protect Owner’s interest therein, all of which must be satisfactory to Owner. 2. Beginning with the second Application for Payment, each Application shall include an affidavit of Contractor stating that all previous progress payments received on account of the Work have been applied on account to discharge Contractor’s legitimate obligations associated with prior Applications for Payment. 3. The amount of retainage with respect to progress payments will be as stipulated in the Agreement. B. Review of Applications 1. Engineer will, within 10 days after receipt of each Application for Payment, either indicate in writing a recommendation of payment and present the Application to Owner or return the Application to Contractor indicating in writing Engineer’s reasons for refusing to recommend payment. In the latter case, Contractor may make the necessary corrections and resubmit the Application. 2. Engineer’s recommendation of any payment requested in an Application for Payment will constitute a representation by Engineer to Owner, based on Engineer’s observations on the Site of the executed Work as an experienced and qualified design professional and on Engineer's review of the Application for Payment and the accompanying data and schedules, that to the best of Engineer’s knowledge, information and belief:
a. the Work has progressed to the point indicat‐ed; b. the quality of the Work is generally in accor‐dance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a final deter‐mination of quantities and classifications for Unit Price Work under Paragraph 9.07, and to any other qualifications stated in the recommendation); and
15‐175 General Conditions ‐37
c. the conditions precedent to Contractor’s being entitled to such payment appear to have been fulfilled in so far as it is Engineer’s responsibility to observe the Work.
3. By recommending any such payment Engineer will not thereby be deemed to have represented that:
a. inspections made to check the quality or the quantity of the Work as it has been performed have been exhaustive, extended to every aspect of the Work in progress, or involved detailed inspections of the Work beyond the responsi‐bilities specifically assigned to Engineer in the Contract Documents; or b. that there may not be other matters or issues between the parties that might entitle Contractor to be paid additionally by Owner or entitle Owner to withhold payment to Contractor.
4. Neither Engineer’s review of Contractor’s Work for the purposes of recommending payments nor Engineer’s recommendation of any payment, including final payment, will impose responsibility on Engineer:
a. to supervise, direct, or control the Work, or b. for the means, methods, techniques, sequences, or procedures of construction, or the safety precautions and programs incident thereto, or c. for Contractor’s failure to comply with Laws and Regulations applicable to Contractor’s performance of the Work, or d. to make any examination to ascertain how or for what purposes Contractor has used the moneys paid on account of the Contract Price, or e. to determine that title to any of the Work, materials, or equipment has passed to Owner free and clear of any Liens.
5. Engineer may refuse to recommend the whole or any part of any payment if, in Engineer’s opinion, it would be incorrect to make the representa‐tions to Owner stated in Paragraph 14.02.B.2. Engineer may also refuse to recommend any such payment or, because of subsequently discovered evidence or the results of subsequent inspections or tests, revise or revoke any such payment recommendation previously
made, to such extent as may be necessary in Engineer’s opinion to protect Owner from loss because:
a. the Work is defective, or completed Work has been damaged, requiring correction or replace‐ment; b. the Contract Price has been reduced by Change Orders; c. Owner has been required to correct defective Work or complete Work in accordance with Paragraph 13.09; or d. Engineer has actual knowledge of the occurrence of any of the events enumerated in Paragraph 15.02.A.
C. Payment Becomes Due 1. Ten days after presentation of the Application for Payment to Owner with Engineer’s recommendation, the amount recommended will (subject to the provisions of Paragraph 14.02.D) become due, and when due will be paid by Owner to Contractor. D. Reduction in Payment 1. Owner may refuse to make payment of the full amount recommended by Engineer because:
a. claims have been made against Owner on account of Contractor’s performance or furnish‐ing of the Work; b. Liens have been filed in connection with the Work, except where Contractor has delivered a specific bond satisfactory to Owner to secure the satisfaction and discharge of such Liens; c. there are other items entitling Owner to a set‐off against the amount recommended; or d. Owner has actual knowledge of the occur‐rence of any of the events enumerated in Paragraphs 14.02.B.5.a through 14.02.B.5.c or Paragraph 15.02.A.
2. If Owner refuses to make payment of the full amount recommended by Engineer, Owner will give Contractor immediate written notice (with a copy to Engineer) stating the reasons for such action and promptly pay Contractor any amount remaining after deduction of the amount so withheld. Owner shall promptly pay Contractor the amount so withheld, or any adjustment thereto agreed to by Owner and Contractor,
15‐175 General Conditions ‐38
when Contractor corrects to Owner’s satisfaction the reasons for such action. 3. If it is subsequently determined that Owner’s refusal of payment was not justified, the amount wrongfully withheld shall be treated as an amount due as determined by Paragraph 14.02.C.1. 14.03 Contractor’s Warranty of Title A. Contractor warrants and guarantees that title to all Work, materials, and equipment covered by any Application for Payment, whether incorporated in the Project or not, will pass to Owner no later than the time of payment free and clear of all Liens. 14.04 Substantial Completion A. When Contractor considers the entire Work ready for its intended use Contractor shall notify Owner and Engineer in writing that the entire Work is substantially complete (except for items specifically listed by Contractor as incomplete) and request that Engineer issue a certificate of Substantial Completion. B. Promptly after Contractor’s notification, Owner, Contractor, and Engineer shall make an inspection of the Work to determine the status of completion. If Engineer does not consider the Work substantially complete, Engineer will notify Contractor in writing giving the reasons therefor. C. If Engineer considers the Work substantially complete, Engineer will deliver to Owner a tentative certificate of Substantial Completion which shall fix the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment. Owner shall have seven days after receipt of the tentative certificate during which to make written objection to Engineer as to any provisions of the certificate or attached list. If, after considering such objections, Engineer concludes that the Work is not substantially complete, Engineer will within 14 days after submission of the tentative certificate to Owner notify Contractor in writing, stating the reasons therefor. If, after consideration of Owner’s objections, Engineer considers the Work substantially complete, Engineer will within said 14 days execute and deliver to Owner and Contractor a definitive certificate of Sub‐stantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as Engineer believes justified after consideration of any objections from Owner. D. At the time of delivery of the tentative certificate of Substantial Completion, Engineer will
deliver to Owner and Contractor a written recommen‐dation as to division of responsibilities pending final payment between Owner and Contractor with respect to security, operation, safety, and protection of the Work, maintenance, heat, utilities, insurance, and warranties and guarantees. Unless Owner and Contractor agree otherwise in writing and so inform Engineer in writing prior to Engineer’s issuing the definitive certificate of Substantial Completion, Engineer’s aforesaid recom‐mendation will be binding on Owner and Contractor until final payment. E. Owner shall have the right to exclude Contractor from the Site after the date of Substantial Completion subject to allowing Contractor reasonable access to complete or correct items on the tentative list. 14.05 Partial Utilization A. Prior to Substantial Completion of all the Work, Owner may use or occupy any substantially completed part of the Work which has specifically been identified in the Contract Documents, or which Owner, Engineer, and Contractor agree constitutes a separately functioning and usable part of the Work that can be used by Owner for its intended purpose without significant interference with Contractor’s performance of the remainder of the Work, subject to the following condi‐tions. 1. Owner at any time may request Contractor in writing to permit Owner to use or occupy any such part of the Work which Owner believes to be ready for its intended use and substantially complete. If and when Contractor agrees that such part of the Work is substantially complete, Contractor will certify to Owner and Engineer that such part of the Work is substantially complete and request Engineer to issue a certificate of Substantial Completion for that part of the Work. 2. Contractor at any time may notify Owner and Engineer in writing that Contractor considers any such part of the Work ready for its intended use and substan‐tially complete and request Engineer to issue a certificate of Substantial Completion for that part of the Work. 3. Within a reasonable time after either such request, Owner, Contractor, and Engineer shall make an inspection of that part of the Work to determine its status of completion. If Engineer does not consider that part of the Work to be substantially complete, Engineer will notify Owner and Contractor in writing giving the reasons therefor. If Engineer considers that part of the Work to be substantially complete, the provisions of Paragraph 14.04 will apply with respect to certification of Substantial Completion of that part of the Work and the
15‐175 General Conditions ‐39
division of responsibility in respect thereof and access thereto. 4. No use or occupancy or separate operation of part of the Work may occur prior to compliance with the requirements of Paragraph 5.10 regarding property insurance. 14.06 Final Inspection A. Upon written notice from Contractor that the entire Work or an agreed portion thereof is complete, Engineer will promptly make a final inspection with Owner and Contractor and will notify Contractor in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. Contractor shall immediately take such measures as are necessary to complete such Work or remedy such deficiencies. 14.07 Final Payment A. Application for Payment 1. After Contractor has, in the opinion of Engineer, satisfactorily completed all corrections identified during the final inspection and has delivered, in accordance with the Contract Documents, all main‐tenance and operating instructions, schedules, guaran‐tees, bonds, certificates or other evidence of insurance certificates of inspection, marked‐up record documents (as provided in Paragraph 6.12), and other documents, Contractor may make application for final payment following the procedure for progress payments. 2. The final Application for Payment shall be accompanied (except as previously delivered) by:
a. all documentation called for in the Contract Documents, including but not limited to the evidence of insurance required by Paragraph 5.04.B.7; b. consent of the surety, if any, to final payment; c. a list of all Claims against Owner that Contractor believes are unsettled; and d. complete and legally effective releases or waivers (satisfactory to Owner) of all Lien rights arising out of or Liens filed in connection with the Work.
3. In lieu of the releases or waivers of Liens specified in Paragraph 14.07.A.2 and as approved by Owner, Contractor may furnish receipts or releases in full and an affidavit of Contractor that: (i) the releases and receipts include all labor, services, material, and
equipment for which a Lien could be filed; and (ii) all payrolls, material and equipment bills, and other indebtedness connected with the Work for which Owner or Owner's property might in any way be responsible have been paid or otherwise satisfied. If any Subcontractor or Supplier fails to furnish such a release or receipt in full, Contractor may furnish a bond or other collateral satisfactory to Owner to indemnify Owner against any Lien. B. Engineer’s Review of Application and Acceptance 1. If, on the basis of Engineer’s observation of the Work during construction and final inspection, and Engineer’s review of the final Application for Payment and accompanying documentation as required by the Contract Documents, Engineer is satisfied that the Work has been completed and Contractor’s other obligations under the Contract Documents have been fulfilled, Engineer will, within ten days after receipt of the final Application for Payment, indicate in writing Engineer’s recommendation of payment and present the Applica‐tion for Payment to Owner for payment. At the same time Engineer will also give written notice to Owner and Contractor that the Work is acceptable subject to the provisions of Paragraph 14.09. Otherwise, Engineer will return the Application for Payment to Contractor, indicating in writing the reasons for refusing to recommend final payment, in which case Contractor shall make the necessary corrections and resubmit the Application for Payment. C. Payment Becomes Due 1. Thirty days after the presentation to Owner of the Application for Payment and accompanying docu‐mentation, the amount recommended by Engineer, less any sum Owner is entitled to set off against Engineer’s recommendation, including but not limited to liquidated damages, will become due and, will be paid by Owner to Contractor. 14.08 Final Completion Delayed A. If, through no fault of Contractor, final completion of the Work is significantly delayed, and if Engineer so confirms, Owner shall, upon receipt of Contractor’s final Application for Payment (for Work fully completed and accepted) and recommendation of Engineer, and without terminating the Contract, make payment of the balance due for that portion of the Work fully completed and accepted. If the remaining balance to be held by Owner for Work not fully completed or corrected is less than the retainage stipulated in the Agreement, and if bonds have been furnished as required in Paragraph 5.01, the written consent of the
15‐175 General Conditions ‐40
surety to the payment of the balance due for that portion of the Work fully completed and accepted shall be submitted by Contractor to Engineer with the Application for such payment. Such payment shall be made under the terms and conditions governing final payment, except that it shall not constitute a waiver of Claims. 14.09 Waiver of Claims A. The making and acceptance of final payment will constitute: 1. a waiver of all Claims by Owner against Contractor, except Claims arising from unsettled Liens, from defective Work appearing after final inspection pursuant to Paragraph 14.06, from failure to comply with the Contract Documents or the terms of any special guarantees specified therein, or from Contractor’s continuing obligations under the Contract Documents; and 2. a waiver of all Claims by Contractor against Owner other than those previously made in accordance with the requirements herein and expressly acknowledged by Owner in writing as still unsettled. ARTICLE 15 ‐ SUSPENSION OF WORK AND TERMINATION
15.01 Owner May Suspend Work A. At any time and without cause, Owner may suspend the Work or any portion thereof for a period of not more than 90 consecutive days by notice in writing to Contractor and Engineer which will fix the date on which Work will be resumed. Contractor shall resume the Work on the date so fixed. Contractor shall be granted an adjustment in the Contract Price or an extension of the Contract Times, or both, directly attributable to any such suspension if Contractor makes a Claim therefor as provided in Paragraph 10.05. 15.02 Owner May Terminate for Cause A. The occurrence of any one or more of the following events will justify termination for cause: 1. Contractor’s persistent failure to perform the Work in accordance with the Contract Documents (including, but not limited to, failure to supply sufficient skilled workers or suitable materials or equipment or failure to adhere to the Progress Schedule established under Paragraph 2.07 as adjusted from time to time pursuant to Paragraph 6.04);
2. Contractor’s disregard of Laws or Regulations of any public body having jurisdiction; 3. Contractor’s disregard of the authority of Engineer; or 4. Contractor’s violation in any substantial way of any provisions of the Contract Documents. B. If one or more of the events identified in Paragraph 15.02.A occur, Owner may, after giving Contractor (and surety ) seven days written notice of its intent to terminate the services of Contractor: 1. exclude Contractor from the Site, and take possession of the Work and of all Contractor’s tools, appliances, construction equipment, and machinery at the Site, and use the same to the full extent they could be used by Contractor (without liability to Contractor for trespass or conversion), 2. incorporate in the Work all materials and equipment stored at the Site or for which Owner has paid Contractor but which are stored elsewhere, and 3. complete the Work as Owner may deem expedient. C. If Owner proceeds as provided in Paragraph 15.02.B, Contractor shall not be entitled to receive any further payment until the Work is completed. If the unpaid balance of the Contract Price exceeds all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) sustained by Owner arising out of or relating to completing the Work, such excess will be paid to Contractor. If such claims, costs, losses, and damages exceed such unpaid balance, Contractor shall pay the difference to Owner. Such claims, costs, losses, and damages incurred by Owner will be reviewed by Engineer as to their reasonableness and, when so approved by Engineer, incorporated in a Change Order. When exercising any rights or remedies under this Paragraph Owner shall not be required to obtain the lowest price for the Work performed. D. Notwithstanding Paragraphs 15.02.B and 15.02.C, Contractor’s services will not be terminated if Contractor begins within seven days of receipt of notice of intent to terminate to correct its failure to perform and proceeds diligently to cure such failure within no more than 30 days of receipt of said notice. E. Where Contractor’s services have been so terminated by Owner, the termination will not affect any rights or remedies of Owner against Contractor then
15‐175 General Conditions ‐41
existing or which may thereafter accrue. Any retention or payment of moneys due Contractor by Owner will not release Contractor from liability. F. If and to the extent that Contractor has provided a performance bond under the provisions of Paragraph 5.01.A, the termination procedures of that bond shall supersede the provisions of Paragraphs 15.02.B, and 15.02.C. 15.03 Owner May Terminate For Convenience A. Upon seven days written notice to Contractor and Engineer, Owner may, without cause and without prejudice to any other right or remedy of Owner, terminate the Contract. In such case, Contractor shall be paid for (without duplication of any items): 1. completed and acceptable Work executed in accordance with the Contract Documents prior to the effective date of termination, including fair and reasonable sums for overhead and profit on such Work; 2. expenses sustained prior to the effective date of termination in performing services and furnishing labor, materials, or equipment as required by the Contract Documents in connection with uncompleted Work, plus fair and reasonable sums for overhead and profit on such expenses; 3. all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) incurred in settlement of terminated contracts with Subcontractors, Suppliers, and others; and 4. reasonable expenses directly attributable to termination. B. Contractor shall not be paid on account of loss of anticipated profits or revenue or other economic loss arising out of or resulting from such termination. 15.04 Contractor May Stop Work or Terminate A. If, through no act or fault of Contractor, (i) the Work is suspended for more than 90 consecutive days by Owner or under an order of court or other public authority, or (ii) Engineer fails to act on any Application for Payment within 30 days after it is submitted, or (iii) Owner fails for 30 days to pay Contractor any sum finally determined to be due, then Contractor may, upon seven days written notice to Owner and Engineer, and provided Owner or Engineer do not remedy such suspension or failure within that time, terminate the Contract and
recover from Owner payment on the same terms as provided in Paragraph 15.03. B. In lieu of terminating the Contract and without prejudice to any other right or remedy, if Engineer has failed to act on an Application for Payment within 30 days after it is submitted, or Owner has failed for 30 days to pay Contractor any sum finally determined to be due, Contractor may, seven days after written notice to Owner and Engineer, stop the Work until payment is made of all such amounts due Contractor, including interest thereon. The provisions of this Paragraph 15.04 are not intended to preclude Contractor from making a Claim under Paragraph 10.05 for an adjustment in Contract Price or Contract Times or other‐wise for expenses or damage directly attributable to Contractor’s stopping the Work as permitted by this Paragraph. ARTICLE 16 ‐ DISPUTE RESOLUTION
16.01 Methods and Procedures A. Either Owner or Contractor may request mediation of any Claim submitted to Engineer for a decision under Paragraph 10.05 before such decision becomes final and binding. The mediation will be governed by the Construction Industry Mediation Rules of the American Arbitration Association in effect as of the Effective Date of the Agreement. The request for mediation shall be submitted in writing to the American Arbitration Association and the other party to the Contract. Timely submission of the request shall stay the effect of Paragraph 10.05.E. B. Owner and Contractor shall participate in the mediation process in good faith. The process shall be concluded within 60 days of filing of the request. The date of termination of the mediation shall be determined by application of the mediation rules referenced above. C. If the Claim is not resolved by mediation, Engineer’s action under Paragraph 10.05.C or a denial pursuant to Paragraphs 10.05.C.3 or 10.05.D shall become final and binding 30 days after termination of the mediation unless, within that time period, Owner or Contractor: 1. elects in writing to invoke any dispute resolution process provided for in the Supplementary Conditions, or 2. agrees with the other party to submit the Claim to another dispute resolution process, or
15‐175 General Conditions ‐42
3. gives written notice to the other party of their intent to submit the Claim to a court of competent jurisdiction. ARTICLE 17 ‐ MISCELLANEOUS

The provisions of this Paragraph will be as effective as if repeated specifically in the Contract Documents in connection with each particular duty, obligation, right, and remedy to which they apply. 17.04 Survival of Obligations A. All representations, indemnifications, warran‐ties, and guarantees made in, required by, or given in accordance with the Contract Documents, as well as all continuing obligations indicated in the Contract Docu‐ments, will survive final payment, completion, and acceptance of the Work or termination or completion of the Contract or termination of the services of Contractor. 17.05 Controlling Law A.

The excavated material shall be disposed of and replaced with trench stabilization material as specified herein.
B. Pipe Bedding: CONTRACTOR shall spread the bedding smoothly to the proper depth and grade so that the pipe is uniformly supported along the barrel to permit proper assembly and inspection of the joint. Bedding under the pipe shall
15‐175 02200 ‐ 11
provide a firm, unyielding support along the entire pipe length. CONTRACTOR shall place subsequent lifts of not more than 12 inches in thickness up to the spring line of the pipe, bringing lifts up equally on both sides of the pipe.
C. Pipe Zone: Pipe zone material shall be carefully placed around the pipe and thoroughly compacted in 6‐inch layers to provide complete support of the pipe and to prevent deflection or damage. The material under the pipe haunches shall be thoroughly "sliced‐in" with a shovel and compacted. CONTRACTOR shall prevent pipe from movement either horizontally or vertically during placement and compaction of pipe zone material.
3.5 Structural Fill:
A. Place structural fill for new trail construction and specified or directed by ENGINEER. Do not exceed loose lifts of 12 inches. Compact each lift to not less than 95 percent of relative compaction. Stop structural fill 9 inches below finished grade in areas to receive topsoil. Moisten material as required to aid compaction. Place material in horizontal lifts and in a manner which avoids segregation. Any subsequent damage to slabs, piping, concrete structures, facilities, or other structures caused by settlement of fill material shall be corrected and repaired by the CONTRACTOR at the CONTRACTOR’s sole expense.
3.6 Compaction
A. Compaction Testing: Prior to commencing field testing, CONTRACTOR shall
notify the City's inspector. At the end of each test period a completed copy of the test results shall be provided to the City. The City reserves the right to require additional tests at no additional cost to the City.
If the compaction specified for trench backfill or embankment is not obtained, CONTRACTOR will immediately stop the material placement and compaction operation and modify the compaction procedure to a method which satisfies the required specification. In no case shall embankment or trench backfill operations proceed until CONTRACTOR is able to compact the backfill material to the satisfaction of the ENGINEER.
3.7 Riprap:
A. Remove brush, trees, stumps and other organic material from slopes to be
protected by riprap and dress to a smooth surface. Remove all unsuitable material to the depth shown or directed and replace with approved material. Compact filled areas as specified for select general backfill. Provide riprap protection as early as the structure foundation construction permits. Prepare the surfaces to be protected as shown. Maintain the trench slopes, riprap geotextile or filter blanket until the riprap is placed.
B. Place riprap on the prepared area:
15‐175 02200 ‐ 12
With a clam‐shell, orange‐peel bucket, skip or similar approved device which will contain the riprap material to its final destination. Do not open the bucket until it has been lowered to the slope on which the material is being placed.
To its full course thickness in one operation.
By methods that do not cause segregation of riprap or displace the underlying material.
To produce a compact riprap protection in which all sizes of material are placed in their proper proportion.
With some hand placing, or rearranging of individual stones by mechanical equipment, or some other approved means to provide a smooth finished surface.
Where filter material and/or riprap are placed under water, increase their thicknesses as shown or as directed.
3.8 Stone Embankment:
A. Preparation ‐ Do not start excavation for each segment until a stockpile of stone embankment material is immediately available at or near the site. Locate the stockpile at a site approved by the ENGINEER. The size of the stockpile shall be sufficient to fill one excavated segment.
B. Sequence of Construction ‐ Excavate the area according to Section 02200‐3.2 to provide a backslope to the lines, slopes and details indicated on the plans or as directed. Excavate and backfill in segments to minimize aggravating stability conditions. Each segment for shear key construction shall not exceed 75 feet in length as measured across the top of each open excavation segment, unless otherwise specified or directed.
C. In the shear key, excavate to a depth of at least 3 feet into firm, stable, undisturbed materials as shown on the plans or as directed. Remove soft or loose materials. ENGINEER will verify sufficient excavation into firm, stable, undisturbed materials in each segment before allowing the backfill. Where called for in the plans or as directed, place drainage geotextile against the excavated backslope. Remove water from the excavation before placing stone embankment material. Backfill all segments on the same day they are excavated. Place and manipulate the stone embankment material in the buttress, inlay or shear key to provide a dense and well‐filled mass to the lines, slopes and cross‐sections indicated on the plans or as directed. Stone embankment placed on slopes steeper than 5H:1V shall be benched.
3.9 Native Soil Backfill:
When Native Soil backfill is used for backfill, CONTRACTOR shall take reasonable precautions to prevent excavated material from becoming saturated beyond the optimum moisture limits, as approved by ENGINEER, at no additional expense to OWNER. CONTRACTOR shall backfill within limits shown on plans above stone embankment in lifts not to exceed 12‐inches in depth. Native soil backfill exceeding 12‐
15‐175 02200 ‐ 13
inches in depth shall be placed on slopes no steeper than 3H:1V, and any native fill placed on slopes steeper than 5H:1V shall be benched. Native soil backfill shall be nominally compacted using a non‐vibratory method due to adjacent existing structures. ENGINEER shall provide visual observation of compaction by method specification, such as three to five passes with an approved vibratory roller operating in the static mode.

B. Manholes Over Existing Sewers
Manholes shall be constructed over existing concrete sewers after first cleaning and applying approved commercial concrete bonding agent to all surfaces of the pipe that will be in contact with the manhole. Manholes shall be constructed over existing PVC or HDPE sewers after first applying a dense coating of clean mortar sand to all pipe surfaces that will be in contact with the manhole, using PVC or HDPE solvent cement, respectively. After the cement has cured, commercial concrete bonding agent shall be applied to the sand prior to placement of concrete.
All sanitary sewer manholes shall successfully pass the vacuum test. After completion of the manhole test, the top of the pipe shall be broken out to the spring line for the full width of the manhole. The exposed edge of the pipe shall be smoothed and pointed with mortar.
CONTRACTOR shall prevent broken material or debris from entering the line.
Flow shall be maintained at all times. ENGINEER's approval shall be obtained prior to diverting flows.
C. Service Line Connections to Existing Sewers
Connections of service lines to existing sanitary sewers shall be made watertight. Connection shall be made where possible to existing tees or wyes previously installed and plugged. The plug shall be removed and connection made in accordance with the requirements of item 3.3 of this section. Transition couplings between dissimilar pipe materials shall be made using approved commercial adapters with stainless steel bands such as Fernco, Caulder, or approved equal.
Where tees or wyes for connection to an existing sanitary sewer main are absent or unusable, connection of service lines shall be made with a strap on type saddle as described in Paragraph 2.17.
Taps shall be installed at a reasonable distance away from a mainline joint, without protrusion into or damage to the existing sanitary sewer. The sanitary sewer shall be supported and bedding material replaced, as necessary, to prevent settlement of the sewer grade.
15‐175 02700 ‐ 20
D. Manhole Connections
CONTRACTOR shall construct openings in the existing manhole base or barrel as required and construct connections that are watertight and that will provide a smooth flow into and through the manhole. All sewer pipe connections, including those at invert level as well as penetrations for drop connectors, conduits, and carry‐throughs, shall conform to the requirements herein.
CONTRACTOR shall provide all diversion facilities and perform all work necessary to maintain flow in existing lines during the connection to the manhole.
E. Capping Abandoned Pipes
Abandoned pipes shall be capped or plugged watertight. Abandoned pipes connected to sewers shall be plugged with gasketed mechanical plugs or non‐shrink grout seals as directed by ENGINEER. Abandoned pipes connected to sewer manholes shall have the plugs or seals installed from the inside of the manhole and the channel shall be reshaped to conform to the standard drawings.
F. Abandoned Manholes, Catch Basins and Ditch Inlets
Manholes, catch basins, and ditch inlets scheduled to be abandoned shall have all connecting pipes capped or plugged. Manhole cone sections, catch basins and ditch inlets shall be removed and become the property of the CONTRACTOR. The remaining manhole structure will be filled with controlled density fill material conforming to Section 02200.
G. Salvaging Frames, Covers and Grates
Frames, covers and grates scheduled for salvage shall be removed by CONTRACTOR and delivered to the City Maintenance Department.
H. Manhole, Catch Basin and Ditch Inlet Adjustment
Concrete and masonry manholes, catch basins, and ditch inlets shall be raised or lowered by removing the existing frames, grates and covers and adjusting the height as necessary to correspond to grade. Structures may be raised or lowered using any of the following methods:
The manhole neck may be extended by the use of riser rings or by reconstructing the neck. Metal rings may be used in the adjustment work provided that the strength and support characteristics of the rings are at least equal to the covers or grates, that uniform bearing of bearing surfaces is assured, and that positive provision is afforded against displacement when in service.
The total distance from the top of the metal frame at its new adjusted grade to the top of the cone shall not exceed 18 inches.
The dome or cone portions of manholes may be cut down and rebuilt provided the batter or slope of the cone does not exceed 6 inches horizontal per 12 inches vertical.
15‐175 02700 ‐ 21
Precast sections and rings removed in the adjusting work may be reused in other adjusting work or in new construction provided they are in good condition and otherwise conform to the specifications. Precast items that are not acceptable for use in the work will become the property of CONTRACTOR.
Mortar for building up existing masonry shall not be placed to a depth of more than 2 inches. Concrete shall not be placed to a depth of less than 3 inches. To conform to these requirements, the existing shells or walls of structures to be raised shall be cut down as necessary to provide space for the new construction.
The exposed top surface of monolithic concrete on which new mortar or concrete is to be placed shall be chipped away to a depth of at least 1 inch to expose firm concrete. The new surface shall be cleaned by brushing and shall be thoroughly coated with an epoxy bonding agent conforming to the requirements of AASHTO M 235 immediately prior to placing the new mortar or concrete. The new mortar or concrete shall then be placed to required grade and cured at least 3 days, after which the frame shall be seated in fresh mortar and brought to proper grade.

Unless otherwise specified, joining shall be accomplished by the butt‐fusion method performed in accordance with the pipe manufacturer’s recommendations, AWWA C906, and ASTM F2620. Socket fusion, and hot gas welding shall not be used. Electrofusion shall not be used except to connect service laterals to sewer pipe via an electrofusion saddle tee. Thermal fusion welding shall be conducted using qualified personnel in accordance with Paragraph 1.02.C. 1) Butt‐fused joints shall be true alignment and shall have
uniform roll‐back beads resulting from the use of proper temperature and pressure. Joint shall be allowed adequate cooling time before removal of pressure.
2) Fused joints shall be watertight and shall have tensile strength equal to that of the pipe.
3) An automated data log shall be generated in accordance with Paragraph 2.05.A for all fusions performed. Data records for shop fusions shall be submitted weekly to the ENGINEER. Data records for field fusions shall be submitted daily to the ENGINEER. All data logger records shall be maintained at the fusion site and the complete set shall be submitted to the OWNER at job completion.
4) Remove the roll‐back bead from the interior of each pipe joint after fusion is complete to provide a smooth pipe surface at the joint.
5) After the roll‐back bead has been removed and before the pipe is placed the trench, video each pipe section and the completed joint to document the condition of the interior pipe wall and joint.
6) During cold (less than 55˚F) and/or wet weather the fusing operation shall be conducted in a climate controlled environment, as recommended by the manufacturer. The fusion area shall be protected from dust, rain, ice, snow, wind or freezing temperatures by using a fusion machine with an enclosed climate controlled fusion area, or by enclosing, insulating and heating the fusing operation as necessary to assure that climate conditions necessary for the fusing operation are maintained.
b. BYPASS PIPE FUSION: Fusion of bypass pumping pipe shall meet all of the requirements listed above. For fusion of bypass pumping pipe on a floating barge, the barge shall allow a working area long enough to have two unfused pipe segments on the
15‐175 15065‐13
barge at one time. Having a barge this long limits the effects of wave action on the fusion machine. For example, if the longest pipe segment were 50 feet long, the fusion barge shall be at least 100 feet long.
c. MECHANICAL JOINING: Flanged joining or other mechanical joining methods shall be provided in accordance with manufacturer’s recommendations. 1) Flange faces shall be in uniform contact prior to bolt
tightening. Bolts and flanges shall not be used to align or join pipes across a gap.

6) CONTRACTOR shall take precautions against galling the Type 316 stainless steel bolts during assembly and torque‐setting operations. Anti‐galling compound shall be used on all flange bolts. If pneumatic wrenches are used they shall be operated at low speed to assure the temperature rise in the threads will not cause galling.
7) CONTRACTOR shall connect flanges for fused pipe segments between manholes and/or existing sewer pipes, including service laterals, on days with air temperature between 45˚F to 65˚F (temperature range shall also apply to water if any portion of the pipeline is submerged). A single flanged end of a pipe segment may be connected and pipe sleeve connection welded outside of this range, if
15‐175 15065‐14
necessary, but the remaining flanged end must be connected and pipe sleeve connection welded within this temperature range to limit abnormal thermal conditions in the pipe reach. Portland area temperature data is included in Attachment 1 of this Section.
8) When connecting the free end of any pipe that partially buoyantly supported – pipe spools from MH B to MH 14, MH D to MH 15R, MH G to MH 18R, MH H to MH 21R, and MH G to MH H – the adjustable stainless steel pipe sleeve connection shall be set at the design location such that the MH flange face is set at 24” as shown on Drawing 000‐D‐165. No pipe sleeve adjustment will be allowed to make up for any change in pipe length due to temperature. The flange connection shall be accomplished by pulling on the HDPE pipe, as needed in a method acceptable to the ENGINEER, with sufficient force that the two flange faces will meet up as specified. Pulling on the existing interceptor, piles (new or to be abandoned), existing docks or sea walls shall not be acceptable.

Basic Erosion Prevention and Sediment Control on residential construction sites
Similar to construction plans, the Erosion and Sediment Control plan must include enough information to enable temporary measures to be properly installed and maintained throughout the project‐‐‐not just the day of the inspection. The plan needs to provide contractors and subcontractors with specific information on when, where and how to install and maintain all BMPs. BMP’s includes erosion prevention measures and construction practices; sediment control measures; and pollution control measures. BMPs need to fully protect the following: all disturbed soils; staging/parking areas; waste/garbage storage areas; stockpiled soils; construction entrances; all sensitive areas, swales, tree groves, etc.; and all stormwater discharge locations such as ditches, storm drain inlets, and swales. These areas must be addressed on the plan and will be inspected during all inspections.
The “Erosion Prevention and Sediment Control” plan must be designed specifically for each construction site, and needs to include the three basic measures: erosion prevention measures; sediment control measures; and pollution control measures. The designer needs to consider construction practices; allow space for large equipment to maneuver; where delivery trucks and forms trailers will park; time of year/anticipated weather; size of project; soil types; topography; on and off‐site stormwater collection; and nearby or onsite seasonal or year‐round water features.
At the construction site, the inspector is required to inspect the following areas. The inspector cannot approve the inspection if each area is not properly protected.
All disturbed soils
Staging areas and waste storage (garbage containers, leakproof washout for concrete, etc.)
Stockpiles and backfill material
Construction entrances
Sensitive Areas: wetlands, tree groves, protected trees
Discharge locations: ditches, swales, catch basins
Please use the information below to assist with preparing a plan that addresses temporary erosion and sediment control on the construction site throughout the project.
Basic Erosion and Sediment Control measures for residential lots:
Area of disturbance: show all areas to be graded, cleared, landscaped, or otherwise disturbed during the scope of the project and the erosion/sediment control measures that are to be used for these areas. All measures except storm water BMPs must be located within the property lines of the property being developed.
Show existing and proposed contours (every 2’‐ 5’ grade change). Show BMPs installed to protect steep slopes, especially when comprised of exposed soils.
Location and type of required perimeter protection. Perimeter protection options include sediment fencing; straw fiber wattles; tackified compost berms; or clean gravel berms. Existing fences do not constitute erosion or sediment control. Perimeter protection, with limited exception, needs to extend around the perimeter of the lot. Basic rule: if equipment can cross the property line or if grading occurs along a property line, perimeter protection should be installed.
Location of staging/storage for materials and stockpiles, realistically scaled. Note: stockpiles must be covered with plastic sheeting unless actively being worked; staging/parking areas must be rocked with 1 ½” clean rock, 4”‐6” in depth.
Location of all required erosion prevention measures. These include (but are not limited to) ground covers such as mulch, straw, clean rock, etc; protection of existing vegetation; secured plastic sheeting; tackified slurry sprays; etc.
Location of all required sediment control measures. These include sediment fencing; straw wattles; catch basin inserts; compost berms; preservation of existing vegetation; wheel washes; etc.
Location of required clean gravel construction entrance (should match proposed driveway area). 1 1/2” minimum clean rock, 4”‐6” deep, is required for construction entrances. On unimproved roads, gravel shoulders must be upgraded with 1 ½” clean rock to support crew parking. NOTE: Flag lots or sites with long driveways or motorcourts will require extended construction entrances.
Location of required leak‐proof garbage containers and leak‐proof pans for all concrete wash‐out/mortar slurry with notation: use of pans and containers is required. The pans must remain on site throughout the project for paint rinse water, mortar and tile saw slurries, drywall compounds, etc. Ground dumping of concrete and mortar washout is prohibited. There are no exceptions to dumping liquid wastes. All garbage, litter, debris must be collected and contained at the end of each work day.
Location of onsite storm water infiltrator or swale, if applicable. Include note: swales must be protected from all construction activity. Use fencing or similar barrier as needed.
Location of nearest storm water catch basins on nearby streets. Non‐woven catch basin inserts are required to be installed in these basins. Biobags are no longer permitted for this use.
Location of nearby stormwater facilities (swales, drainage ditches, etc.) with appropriate BMPs to protect from silt/sediment during construction. All swale locations must be protected (fencing, boulders, etc.) during construction to prevent damage to the soils during construction.
Notes indicating Lake Oswego Wet Weather Season requirements (October 1 through May 31); the “Additional Erosion & Sediment Control Notes” (copies available upon request).
Notes indicating when and how soils will be permanently stabilized at the end of the project (landscaping, ground cover, etc.).
Anticipated construction schedule—the proposed plan should reflect measures that work with the construction schedule.
Name and phone number of contact person responsible for installation and maintenance of erosion and sediment control measures.
If you are unfamiliar with the basic principles of erosion prevention and sediment control, please consider the services of a private contractor for design, installation, and maintenance. It is the permit holder’s responsibility to maintain a working knowledge of current requirements and for ensuring all utility installers, contractors and subcontractors on the construction site adhere to the requirements. Contractors are responsible for reading all approved plans, permits, and attached notes, memos and details prior to starting any project. This may be the single best way to stay familiar with current regulations and requirements. Additional information is available at: http://www.clackamas.us/wes/designmanual.html, the link for the regionally adopted Erosion Prevention and Sediment Control manual. The Department of Environmental Quality has also produced a manual which provides a basic understanding of the principles at: http://www.deq.state.or.us/wq/stormwater/docs/escmanual/manual.pdf. The City of Lake Oswego has several informational flyers and forms that provide information that applies to most sites. updated May 9, 2013. Please replace all earlier versions with this current version.
