3 QUESTIONS & ANSWERS

3.1 Is there flexibility in the project schedule to be adjusted to accommodate existing work commitments?

3.1.1 The schedule provided in the specifications is a preliminary scheduled intended to establish milestones and convey anticipated durations for developing crew sizes. Following contract award, a pull plan session will be conducted to further develop the schedule and modifications to sequencing will be considered as long as overall completion milestones can be maintained.

3.2 Which entrances can be used for construction and demolition? Are trash chutes allowed?

3.2.1 All entrances to the building may be used for construction purposes. It is the contractor's responsibility to assure that the premises are secured at the end of the workday. Use of trash chutes will be permitted but shall be coordinated with window demolition to minimize weather impacts.

3.3 I am looking into the specifications, and it does call out the camera manufacturers, but not the video management system itself. Also, it doesn’t call out specified access control manufacturers that I saw. Is there an access control and/or video surveillance system already existing at their facility?

3.3.1 The owner utilizes a Genetec Server, and Genetec Archiver for door controls, and camera recording at other buildings. They would like to utilize these same head end pieces of equipment, and software systems.

3.4 In some of the resident rooms, it appears the existing surface mounted light fixtures may be obstructing the sprinkler heads. What is the intent for these locations?

3.4.1 Where sprinkler heads need adjusted to accommodate ceiling mounted devices, the fire sprinkler contractor shall move or extend the sprinkler head to accommodate. Bid Package #01 shall include 15 SF of drywall patching per Keynote #01 of the reflected ceiling demolition plans to accommodate this, or similar, work

3.5 In some locations there is exposed wood above ceiling. Please confirm how this will be addressed?

3.5.1 It is the intent of the design documents that exposed wood will either be covered or removed during construction to meet fire code requirements.

3.6 What is the intent of sequencing the removals of the asbestos containing transom panels above the windows and their replacement with new materials?

3.6.1 Bid Package #01, #07, and the construction manager shall coordinate to identify opportunities where the weather will accommodate a substantial number of the transom panels to be removed and new windows and panels installed prior to a potential rain event. As transom panels are removed, Bid Package #01 shall install plastic to mitigate wind or animal infiltration.

3.7 The hazardous materials drawings and report do not provide enough information to quantify the lead abatement scope. Please provide further clarification.

3.7.1 See 2.6 of this addendum for further details.

3.8 Is NewStar an acceptable light fixture equals manufacturer for fixtures 6A, 6B, 6C, and 7?

3.8.1 Yes, NewStar is acceptable as a fixture equals for these fixture types.
