3) The drawings are missing the restroom detail for the following restrooms: 26A, 27A, 25B, and 28B.

Answer: Work in these rooms is limited to what is noted on A10.1 – Room Finish Schedule and replacement of the lockers. No details are needed.

4) The Phasing Diagram indicates that Phase 1B will be followed by Phase 2B, 2C, 2D then phases 3B, 3C so forth and so on. The phasing logic will not work with the installation of the resilient tile flooring unless DeCA will accept cutting of tiles where phases meet. Will DeCA accept cut tiles or is the successful contractor to schedule resilient tile flooring out of sync with the phasing diagram?

Answer: The intent is to install the flooring sequentially from west to east across the Sales Area / Checkout without cut tiles. It is expected that work in Phases 2A-9 and 3B-7B will progress more quickly than Phases 2B and 2C because no refrigeration or reconfiguring is involved. Ideally, Phases 2C and 7B conclude at about the same time and the Contractor then moves on to Phase 3C. Flooring work in Phase 2D should be done during store non-operating hours after completion of Phases 3C and 9 in order to maintain tile alignment.

5) Will grinding of the VCT mastic and floor substrate using an orbital grinder and vacuum be an acceptable alternative to the shot blasting?

Answer: No.

6) Is moisture mitigation for the resilient tile flooring supposed to a part of this proposal?

Answer: No, but moisture testing is. If moisture levels test above the acceptable limit of the new flooring manufacturer, mitigation will be added to the project as a differing site condition.

7) Please confirm the information for the Seasons 4 is accurate (Weight/Dimensions/Load/Capacity)

Answer: There was a typographical error in the Dehumidification Unit Schedule on M6.1 regarding the equipment weight. The indoor unit should be 11,250 lbs instead of 32,000 lbs per the information provided from Seasons 4. The outdoor unit weight was correct at 5,500 lbs.

There was a typographical error regarding the indoor unit dimensions. They should be 321-1/2”L x 90”H x 96”W per the information provided from Seasons 4

The cooling/heating load/capacities are correct per the information provided from Seasons 4

Answer: No modifications are needed to the existing panels to bring them up to current code. The second sentence of note 2 may be disregarded. Existing panels may be reused and overcurrent protective devices replaced as necessary to match new equipment.

16) E2.1 General Note G. What is the actual amount of temporary loading available (to be verified by the contracting officer at the time of the bid)? Will a temporary generator be required, what size will it be, how long will it be in operation?

Answer: DeCA or Civil Engineering to advise if capacity should be different than what was found during site investigation. At time of site visit, the meter showed capacity for an additional 150 kVA. The need and duration of a temporary generator is dependent on the Contractor’s means and methods to meet phasing requirements.

17) E2.2 Keyed note 6. There is no demolition reference to an existing keypad however, note 6 references connecting it to existing wiring. Is this keypad to be connected to an existing security system and if so, what is the current system and who is the contact for alterations? Does the base require a specific vendor for security systems?

Answer: New keypad is to be reconnected to an existing security system. Keypad / electric latch should be in accordance with door hardware specification 087100. The current system and a specific contact for alteration is unknown. Contractor shall be expected to provide a witnessed functional test of new lock equipment.

18) E6.1 General Note c. Is one hour the maximum time power can be shut down for circuit transfers? Will the power shut downs be performed at night?

Answer: Power shut downs should be performed while store is not in operation. Outages of equipment may exceed one hour as long as temperature to refrigerated areas is maintained and other equipment is energized prior to operations needed. Shut downs should be coordinated with the store manager and be expected to take place at night.

19) E6.1 Keyed Note 15. How much temporary power is required? Who determines what will need to be placed on temporary power? Will temporary power require overnight/after hours installation?

Answer: Temporary power is expected namely to support temporary refrigeration equipment as refrigerant is changed. Temporary power to temporary coolers or other equipment may be done at any time, but if it requires interruption to the building power, the outage should be scheduled and performed during non-business hours. The amount of temporary power needs to be coordinated by the Contractor and is dependent on their schedule, means, and methods. Other temporary power (to non-refrigeration equipment) may be used to facilitate phasing work as Contractor sees fit.

26) Will the contractor be provided/allowed to maintain at least 1 dock bay for dumpsters during renovation?

Answer: No

27) 01 50 00-8; the decibel rating for sound is equivalent to a garbage disposal, and thus could be proven required by the Contracting Officer at each phase of the project. The cost and time to construct noise barriers at each phase seem prohibitive to schedule and prudent fiscal responsibility. This also section also discusses IAQ for guidelines that are listed to Hazardous materials – specifications indicate no hazardous materials have been identified in the study, please confirm. Given the scope of work, may the bidding Contractor assume a typical barricade for sales floor phases to include a 4’ plywood framed barrier at perimeter with 6 mil poly to deck and taped at the seams?

Answer: It is not mandatory to construct noise barriers. The Contractor is required to provide “sound attenuation batts and other construction as necessary or perform work after store hours” to prevent noise levels in patron areas from reaching 82db or higher. There are no known hazardous materials. See Drawing G2.0 – Composite Construction Phasing Plan – General Note D for temporary barriers. 6 mil poly is acceptable.

28) Crawl Space:

a. What is the clearance height of the existing crawl space?

b. What is the opening size of the existing crawl space access?

Answer: Proposal due date will be extended to 14 May 2015.

29) We have been unable to verify during the site visit what exactly is under the mechanically fastened EPDM membrane. Can you confirm what is stated on the drawings, EPDM membrane mechanically fastened over 3” of rigid insulation over metal deck is correct so we may bid appropriately?

Answer: A DeCA-furnished Roof Inspection Report dated December 2013 indicates the existing low-slope roofing system to be the original mechanically fastened EPDM system from 1994. Assume the existing roofing system to be as noted on Drawing A4.0.

30) We were unable to access above the ceiling at the sales floor during the walkthrough. The plans provided do not convey building cut sections, or elevations of structure to determine the roof deck height throughout the building to quantity full height partitions. Please provide as-built structural plans, or provide deck heights throughout the building to determine quantities for the bid.

Answer: See attached record drawing A4.1.
