SPECIAL NOTE FOR SURFACE PREPARATION AND PAINT APPLICATION

I. DESCRIPTION Clean and paint new and existing structural steel to the limits specified in the applicable Special Notes and as directed by the Engineer in accordance with the Kentucky Transportation Cabinet, Department of Highways, 2012 Standard Specifications for Road and Bridge Construction and the following requirements:

II. CONSTRUCTION

A. Surface Preparation 1. Solvent Cleaning. Prior to using any of the methods of substrate preparation

herein, remove visible grease and oil from the surface. Clean the surface in accordance with SSPC-SP 1 to remove oil, grease, and any other surface contaminants. Only use solvents or detergents that are acceptable to the coating manufacturer and the Department. Use clean cloths for the final wiping of the cleaned surface.

2. Pressure Washing. Clean all structural steel by pressure washing. Size the pressure washers so that no combination of hose length or pressure washer placement will result in an output pressure less the 4,500 psi or more than 5,000 psi from any spray wand at any pressure washing location. Hold the wand nozzle a maximum of twelve (12) inches from the surface being pressure washed approximately normal (perpendicular) to the working surface. Use clean, potable water for pressure washing. Do not use water from streams, ponds, lakes or rivers. At the discretion of the Contractor, a non-sudsing, biodegradable detergent may be added to the water to optimize the cleaning operation. If a detergent is used, thoroughly rinse the surface afterward. After the surface is pressure washed and allowed to dry, inspect it for remaining visible dirt. Wipe the dried surface with black and white rags to ascertain cleanliness. Re-clean and rinse as necessary to remove all contaminants on the working surface. On all surfaces not cleaned satisfactorily by pressure washing, employ one or more of the following methods including: 1) Hand scrubbing using wet rags. 2) Solvent cleaning by wiping with solvent-soaked rags. 3) Steam cleaning. After using any additional cleaning procedures, pressure wash those areas.

3. Mechanical Surface Preparation. After pressure washing, perform mechanical surface preparation on all surfaces not possessing clean, adherent paint (e.g. rust, loose paint, or loose mill scale). All surfaces requiring mechanical surface preparation will be cleaned to an SSPC-SP3. Perform all mechanical surface preparations using power tools. Equip all power tools with vacuum shrouds.

CARROLL COUNTYFE02 021 0042 B00043N

Contract ID: 162913Page 9 of 62

REVISED ADDENDUM #1: 9-27-16

Maintain and operate all vacuum shrouded power tools to collect generated debris. Equip all the air exhausts of the vacuum systems with HEPA filters.

After tool cleaning and prior to painting, remove all residue, dirt, dust, or similar contaminates from the cleaned surface to the satisfaction of the Engineer. The Contractor is solely responsible for any damages arising from the surface preparation operations.

B. Paint Application. Do not paint areas until they have been inspected and approved by the Engineer (or at the direction of the Engineer, the Department’s Inspector). Apply paint only to dry, clean surfaces. Apply paint according to the manufacturer’s recommendations with the exception that no paint will be applied unless steel temperature and ambient air temperature are above 32° F. For new steel, apply in the shop a Class 1 primer from the approved list referenced in the SPECIAL NOTES FOR PAINT. For new installed structural steel and existing prepared structural steel apply a Class IV (TYPE VI) coating system from the approved list referenced in the SPECIAL NOTES FOR PAINT. Apply paint according to the manufacturer’s recommendations and Section 607 of the Standard Specifications.

The finish coat shall be blue closely matching Federal Standard 595 FSX5095.

C. Damages. Take all steps necessary to preclude damage to public property from paint overspray. Those steps may include changes in the type of containment or cessation of spraying operations. The Contractor is solely responsible for any damages arising from the painting operations.

D. Repair of Paint Defects. Repair all defects in new paint.

E. Residual lead paint may still be on bridge. The Contractor is advised to take all necessary protective measures including worker safety and environmental regulations when executing this work. The Department will not consider any claims based on residual lead paint.




SPECIAL NOTE FOR PAINT

Use a coatings system from an approved supplier. A list of approved suppliers may be found in the Department’s List of Approved Materials maintained by the Division of Materials. All paint supplied must conform to the applicable Special Notes contained in this proposal. The Department requires acceptance testing of samples obtained on a per-lot basis per-shipment. The Division of Materials will perform acceptance testing. At his option, the Engineer may elect to conduct more frequent sampling and testing. Test samples will be taken at the Contractor’s paint storage site. Department personnel will perform sampling. Allow (10) working days for testing and approval of the sampled paint.

Note: It is the Contractor’s responsibility to maintain an adequate inventory of approved paint. The Department assumes no responsibility for lost work due to rejection of paint or approved paint subsequently found to be defective during the application process.




SPECIAL NOTE FOR TRAFFIC CONTROL ON BRIDGE REPAIR CONTRACTS

I. TRAFFIC CONTROL GENERAL Except as provided herein, traffic shall be maintained in accordance with the 2012 Standard Specifications, Section 112. All items of work necessary to maintain and control traffic will be paid at the lump sum bid price to “Maintain and Control Traffic”. Contrary to Section 106.01, traffic control devices used on this project may be new or used in new condition, at the beginning of the work and maintained in like new condition until completion of the work.

II. TRAFFIC COORDINATOR Furnish a Traffic Coordinator as per Section 112. The Traffic Coordinator shall inspect the project maintenance of traffic, at least three times daily, or as directed by the Engineer, during the Contractor’s operations and at any time a lane closure is in place. The personnel shall have access on the project to a radio or telephone to be used in case of emergencies or accidents. The Traffic Coordinator shall report all incidents throughout the work zone to the Engineer on the project. The Contractor shall furnish the name and telephone number where the Traffic Coordinator can be contacted at all times.

III. SIGNS Contrary to Section 112.04.02 , signs will be measured once only regardless of how many times set up, moved, or relocated. The contractor is to install warning signs for wide loads in advance of the bridge under the direction of the Engineer. This shall be paid under the lump sum bid price to Maintain and Control Traffic. The Department will not measure installation, maintenance, or removal for payment, and will consider these incidentals to Maintain and Control Traffic.

IV. LANE CLOSURES Lane closures will only be paid once. If lane closures are left in place continuously over three days it is the contractors responsibility to install striping meeting MUTCD STANDARDS. Lane closures will not be permitted on these days:

Easter Weekend (Thursday-Sunday) Memorial Day Weekend (Friday-Monday) Independence Day Weekend, Labor Day Weekend (Friday-Monday) Thanksgiving Day Weekend (Thursday-Sunday) Christmas/New Years (December 24-January 2)


Contract ID: 162913 of 62


V. PROJECT PHASING & CONSTRUCTION PROCEDURES

Lane closures are to be in place during the construction process to move loading to the opposite side of the retrofit being installed. Similar retrofits are to be placed one at a time. Therefore multiple gusset plate retrofits or stringer retrofits will not be allowed at one time, but one each of the gusset plate and stringer retrofits can occur during the same time as long as the retrofits are on the same side of the bridge. Length of lane closure will be the entire length of the truss spans plus tapers. Single lane closures will be in effect for a maximum cumulative total of 24 calendar days. This limit includes total days of lane closures in both directions. Maintain one lane of traffic during construction in accordance with Standard Drawing No. TTC-100-03 for lane closures. The minimum clear lane width required is 11’-0”. Flagging shall be used during peak traffic (6:30am to 8:30am and 3:00pm to 5:00pm).

VI. VARIABLE MESSAGE SIGNS If deemed necessary by the Engineer, variable message signs will be installed, operated, and maintained by the Department.

VII. TEMPORARY SIGNAL Provide, install, and maintain a temporary multi phase traffic signal in accordance with Standard Drawing No. TTC-110-02. The Contractor must provide a 24-hour contact person and number available to maintain the temporary signals as needed. The signal may be used in lieu of flagging for all hours other than those mentioned in paragraph V.
