A: Unclear on the question. See specification section 01 11 00, par 1.5 and par. 1.6.

12.) Q: Can a dumpster be brought and left in the alleyway between the buildings during the construction?

A: Dumpster cannot be placed in the alley for the entire construction duration. See spec section 01 11 00, 1.5.2.4 and 01 50 00, par. 1.4.

A: See Q&A 3.).

23.) Q: Can the screws be broken off at the concrete or do they need to be taken out completely?

A: Screws can be broken off at the top of the concrete deck.

24.) Q: Sheet A-104 Detail B. Shows drain being raised. Wouldn’t we want to sump the drain to allow water to flow into it? Also are we supposed to create a valley tapered to the drain? Or build up drain and create hip with insulation to allow water to flow away?

A: The intent is to allow water to flow to the re-installed drain by creating a tapered valley as shown on the contract drawings. However, the existing drain has been installed too low and lacks the proper substrate materials under the membrane, resulting in an unsafe area to walk and improper tapering of the insulation. Raising the drain and installing the proper substrate will improve the existing condition.

25.) Q: Bidding schedule 0001-0006 Part of bid documents dated Feb, 2015. Should our pricing be based off of these quantities?

A: Yes; see Section 00 80 00, par. 1.5.

A: See Q&A 16.)

27.) Q: How thick is the proposed insulation?

A: See Q&A 4.)

28.) Q: A105/ A106 show ballast description. Three different weights are needed at different locations, 40 PSF, 60 PSF and 90 PSF which we need to engineer. Detail indicates "continuous ballast using sand bags wrapped into continuous banks(100' roll length minimum) of polyester net and connected together". How are we expected to handle a 9,000 LB sandbag? I believe Note 2 clarifies that we are to use many multiply sandbags that get wrapped in netting to keep them all together. Please confirm.

A: The specified ballast load is to be constructed by stacking multiple 50-pound sand bags.
