General:

1. Will the contractor be provided with an electronic version of the CAD file of the

“Construction Documents”? Yes.

2. What specific locations in the 19 buildings included in this project are known to contain lead paint and/or asbestos? Asbestos surveys are available and can be provide if requested.

3. What specific locations in the 19 buildings included in this project are required to be tested for lead paint and asbestos prior to commencing any work? Refers to the VHA

Master Specifications Document, Section 00 01 00, General Requirements, Section 1.6

Operations and Storage Areas. Please clarify what spec section you are looking at.

Testing for Lead based paint and asbestos not in Section 1.6. General Requirements is section 010000

4. In accordance with Section B, can the contractor place a construction office trailer and storage trailers for tools and materials in the gravel area near the former ball field (3rd base side)? Yes this is acceptable.

5. Will a construction fence in accordance with Section G be required around the contractor’s office and storage trailers? Yes.

6. Will a construction fence in accordance with Section G be required around temporary generators (such as the 750kW generator listed on Sheet 61-E101)? Yes.

7. Most of this project involves work indoors. Are there any areas that will require a construction fence? See previous questions.

8. See paragraph 1.6.I.4. What constitutes a “major interruption”? What is the difference between an “interruption” (paragraph 1.6.I.2) and a “major interruption”? Major interruption is any utility impact that prevent patient care.

9. Sheet G003: Note F. under “Architectural General Notes” states that dumpster location must be identified prior to bidding. Is this correct? And if so, what steps do we take to achieve this? Dumpster location can be coordinated at the pre-construction meeting.

10. Sheet 2-E101: Note 17, the panelboard referred to as 2-FP-EM-GCB cannot be located on the drawing. Is this a type-o? Yes this is a typo, the panel name in the note should be

2-FP-SB-GCB to match drawing.

Building 1

1. Sheet 1-E101: Can crawlspace access door at room 40 be opened? (Josh Leow was not able to open it during the site visit.) Is the door in room 6 (note 10 on this sheet) the only means of accessing the conduit route called out in note 26 on this sheet? It is my understanding that the electrical shops have used the crawl space door at room 40 in the past, but the A/E never opened it. The door noted by key note 10 was opened and can be used to access the conduit route in question.

Building 3

2. The apartment is occupied 24 hours/day. The “Work Hours” on the sheet are listed as M-

F 5pm – 6am, which includes the time the tenants are likely to be asleep. Can the work in this building occur during normal business hours (8 am to 5 pm)? Yes, work in this building can be done during normal business hours, or as directed by the COR. All working hours in all buildings shall be confirmed with COR prior to beginning work.

RFI Questions IV:

1. Sheet 1-E101 shows conduit and conductors being routed from 1-FP-GEN-GWA (in

Building 1) to Building 63; the sheet shows the route moving from Building 1 Electrical

Room 40 through the corridor and from the corridor to Building 63. The route is required to use underground crawl space to exit Building 1 and a duct bank across the courtyard to enter Building 63. This crawlspace does not appear to be accessible, and there is no exit from Building 1 to the courtyard along this path as a fully enclosed corridor connects the two buildings. Would it be allowable to run the conduit and conductors overhead? If not, what path should the contractor utilize to achieve this task? The crawl space is accessible by door, see note 10. Feeder shall exit crawl space, underground into courtyard in corner of building, angled away from corridor.
