77. 12-15-22 01-09-2023 Are there any special requirements for recertifying the floodwall after excavating so close to and below the existing floodwall foundation?

Refer to geotechnical report for disturbed soils adjacent to the flood wall.

78. 12-15-22 01-09-2023 Drawing FP1.00 identifies an existing underground fire main to be removed and to see civil plans. What depth is this underground fire main?

Contractor to verify. Approximately 8’ below grade, but each item defined for removal is constructed at different depths. A PDF of the survey is included with the responses. Reference Addendum 1 Civil Drawings & Addendum 1 Fire Alarm and Sprinkler Drawings_01.

79. 12-15-22 01-09-2023 Drawing FP1.00 identifies an existing underground fire main to be removed and to see civil plans. Is this the same remove water pipe note on drawing CD100?

87. 12-15-22 01-09-2023 Detail 2/A4.01 Floor System states to see structural, the structural drawing details such as maybe detail B4/SF502 that appears to match states to see plan and plan notes.

What plan and plan notes are referenced?

B4/SF502 is referenced from D1/SF101 (as noted on the detail). See that plan and notes on that plan for details of the floor slab on metal deck.

88. 12-16-22 01-09-2023 Figure 1 on page M5.11, the schematic on page M6.01 and the heat exchanger diagram on page M6.03 are all different. Can you advise which diagram is correct, particularly interested in the motorized isolation valves?

All steam control valves shown on plans for the referenced heat exchangers to be provided. The motorized isolation valves on the hydronic side of both heat exchangers are also required. Provided by contractor.

89. 12-16-22 01-09-2023 Any known existing thickness and reinforcement of the asphalt/concrete?

Contractor to verify. Assume 8” at concrete and asphalt paving

90. 12-16-22 01-09-2023 Any available detailed drawing of the storm drainage basin - assuming it is different from the rest of the civil work.

See revision to S-602 for retaining wall detail and additional notes in this area on the revisions to the Civil Sheets. Stormwater facility is concrete bottomed area with retaining walls. The eastern end is design as a ramp to allow the facility to back a pump trailer in and hook up to the PTO pipe in the event that the pump house can’t keep up with flow or there is an emergency situation.

Seams and joints need to have neoprene seals to prevent excess seepage from the facility.

Verify feeder from MH-11 to T-38 is incorrectly marked as 120-208V secondary feeder and is actually the primary new UG Duct Bank.

Feed to existing transformer from Manhole 11 indicated is incorrectly labelled as 120-208V. The section labelled this way is Medium Voltage Power (4160V) and should use (3) 4/0 + 1/0 CU ground as indicated leading up to Manhole 11.
