1 of 4

ADDENDUM NO. 2 QUESTIONS & ANSWERS

(May 21, 2015)

Q1: As discussed during the Mandatory Site Walk, please confirm whether the storm drain work described on plan sheet L-050 will be carried as an owner allowance or if the contractor is required to provide pricing for this scope. If contractor is required to provide pricing, we will need a follow up meeting be scheduled as soon as possible so our plumber is able to review each of the rooms for access and understanding of the existing conditions.

A1: Contractor will only be responsible for connecting storm drain outside of building at the three (3) locations shown on the civil plans. UCSD HDH will provide all of the interior piping, wall coring, interior repairs and waterproofing

Q2: As discussed during the Mandatory Site Walk, please confirm the existing concrete over the top of the Utilidor does not reside directly on the 8” thick lid as indicated in the ‘As-Built Util ity Tunnel Section’ shown on sheet C-302. For bid purposes, please identify the concrete thickness to be removed and the soil depth beneath the existing concrete. Please confirm waterproofing of the util ity tunnel is not required.

A2: Please see concrete pavement section on C-001. Q3: Reference Detail 1/L-104, the 6” dimension on the left side of the concrete is

assumedly mis-alligned. The civil drawings provide a section for vehicular concrete on grade and pedestrian concrete over the util idor. Please provide a concrete paving section for pedestrian concrete over grade or confirm the concrete section for pedestrian concrete is 4” thick over 2” washed concrete sand.

A3: 6” dimension was a typo, this has been removed. Pedestrian concrete is 4” thick over 2” of sand –note: reinforcement per civil, 2” washed concrete sand under both pedestrian and vehicular concrete: This will be clarified in addendum #2

Q4: Reference Detail 8/L-104 for Porous concrete. The detail says to reference civil for the depth of the ¾” washed aggregate drain rock. The civil does not address the depth of the drain rock. For bid purposes, please specify the depth of the aggregate base to be used beneath the porous paving.

A4: The porous concrete shall have a minimum 12” of ¾” crushed rock, over processed subgrade soil with 95% relative compaction.

Q5: Please confirm the bench as shown below is the same as the R-2 bench between the columns on the opposite side of the courtyard. If not, please specify what is happening between the columns.

Q7: Reference sheet C-001 ‘Bioretention (For Reference Only)’ detail (issued in addendum #1). This detail conflicts with detail 1/L-110. Please clarify which detail should be used for the bio-retention engineered soil and gravel depths. Detail 1/L-110 does not show any gravel and the detail on C-001 shows 12” of gravel. Please clarify.

A7: The detail is shown for the purpose of the perforated pipe only, the Bioretention details shall be per 1/L110.

Q8: Please confirm tree staking is not required for trees installed in the bioswale. Staking will l ikely puncture the bioswale liner.

A8: No staking through liner, an alternate detail will be provided in addendum #2 Q9: Reference 1/L110, keynote 11. Please provide the UCSD standard for waterproofing.

A9: This detail will be updated in addendum #2 to confirm waterproofing Q10: Reference 1/L110 and 10/S-301. On detail 1/L110, the corten appears to embed into

the concrete wall. Detail 10/S-301, the corten terminate at the top of the wall. Please confirm the corten will terminate at the top of the wall as shown in detail 10/S-301.

A10: Detail 1/L110 will be revised to not have corten steel embed –will match structural this will updated in addendum #2

Q11: Reference 1/L110, on the top of the left wall at the bioswale, there appears to be gravel mulch on top of the wall.

A11: Yes there is a narrow gavel strip on the south wall (3” width) to prevent corten steel bleeding on concrete –concrete walk in this arrow slopes away from the gravel. This will be updated in addendum #2

Q12: Reference Detail 3/L-111 and Concrete Pavement details/C-001. Detail 3/L-111 shows 4” washed concrete sand base beneath the firelane paving. The concrete Pavement Details on sheet C-001 says concrete will be placed over 95% compacted native subgrade. Please clarify if aggregate base is required under vehicular concrete.

A12: Detail 3/L-111 has 2” sand, 4” dimension refers to concrete section under light, all concrete pedestrian and vehicular to include 2” depth of washed concrete sand

Q13: The two Platanus racemosa trees at the south edge of the project are slated to be moved north just a few feet toward the Argo Hall building. There is utility mark-out around the existing trees. One of the trees shows an electrical l ine passing just a few feet away from the trunk and the other tree to the east shows a water line in the proposed planting location. The tree further to the west is not a good candidate for relocation and if both trees are not relocated, the symmetry is unbalanced a bit. Please clarify if these trees are to be relocated as shown on the plan or if these can be demolished and replaced with 36” box trees.

A13: One Sycamore will remain in place, eastern one will be relocated to planting area to the west (adjacent to lawn area). This change will be reflected in Addendum #2

Q14: Please confirm the quantities on sheet L-303 are for reference only and contractors are responsible for take-off as shown on the plan.

A14: Yes they were for reference only and have been removed, contractor responsible for confirming quantities

Q15: With the limited duration to complete the project, please confirm work hours can be extended from 8:00 am to 4:30 pm Monday through Friday to 8:00 am to 7:30 PM Monday through Saturday. We believe the work will require significant overtime to be completed on time.

A15: Work hours can be extended to Monday through Saturday 7am until 6:30pm. However, you are not allowed to do any noisy work prior to 8am on any day unless requested and approved by UCSD prior.

Q16: Detail D/L-203 mentions the use of decoders implying the irrigation system may be a two wire system. Notes on plan sheet L-201 indicate connection to existing spare control wires. Please clarify if the irrigation system is a two wire system or a conventional wire system.

A16: The detail in question does not imply that the irrigation system is a 2-wire system. Detail D/L-204 (2.) states "a decoder unit as required. Refer to Legend". The Legend does not have anywhere on it the use of 2-wire components including decoders. Notes on sheet L-201 are correct. They indicate a conventional system with a connection to existing spare wires. Nowhere in the construction documents does it say to connect to or use a 2-wire decoder system.

Q17: The concrete along ridge walk is stippled per paving type C1 but is identified below as paving type C1 and C3. Please define where paving type C3 will be used or clarify if all paving is to be type C1 with scoring as shown.

A17: This will be confirmed in Addendum #2

Q18: Reference Specification 02768; Section 2.4 Concrete Materials: Paragraph A-1 & 2. Please confirm that Type III Cement is require for the project. The adjacent projects util ized type II/V cement.

A18: Assume type II/V for site concrete this will be confirmed in addendum 2

A:19 Refer to addendum #1 -detail 2 -L112

Q20: The catch basins attached to the 6" pvc storm drain are not labeled as to what size they are supposed to be in any of the documents sheet C-301.
