RFI Responses:

1. Please confirm that the contractor is to provide an additional addressable FACP, which will be "interfaced" with an existing FACP in Building 305 (per Sec. 2.3, Pgh A, Subpara 1). Existing FACP located in corridor will be used.

2. Section 1.1. Pgh C, Subpara 1: This indicates that Bldg. 305 A-B to have an "automatic digitized voice fire alarm signal with emergency manual voice override...". Is the intent to re-use the existing FACP and not install an additional panel (as indicated in Item 1 above).

If so, is the existing panel already equipped for voice? If not, does it have the capacity for the necessary equipment for expansion? Provide details of the existing panel, if it is to be reused. Existing FACP will be re-used. It is equipped to be used with voice devices.

3. Section 1.2, Pgh. D: This indicates that existing devices "...reused by the Contractor..."

should be “…equipped with an addressable interface device compatible with the new equipment being installed." What device types and quantities exist which require mod-ules? Contractor to provide new devices. Most of old devices were damaged during pre-vious demolition effort.

4. Section 1.2, Pgh E; This indicates that existing equipment should be warrantied as new. Is this correct? New devices to be furnished and warrantied as new.

5. An annunciator is specified per Section 2.5. The drawings do not indicate the location of the annunciator. Where does it go?

Local annunciator not required as determined by VA fire protection personnel.

3. We expect the trim to be removed as part of the HAZMAT abatement on the existing caulk. Is the contractor responsible for replacing this trim? The existing windows needed metal panning because they were not built to fit the opening. The new windows will need to be ordered to fit without panning. Contractor to verify masonry opening sizes and order to fit.

8. The drawings call for existing insulation in the crawlspace to remain. However, during the site visit, we observed beaded water on the surface of insulation, and can provide photos of this water. Should water damaged insulation be removed and replaced? VA Shops have repaired the steam leak that was creating the water issue. Some insulation will need to be removed to accommodate demo of utilities to be decommissioned/abandoned. Any insu-lation damaged due to demo efforts shall be replaced. Contractor to notify COR/CO of any other damaged insulation encountered.

9. There is a deflection in the floor of approximately 1 inch, about 6 ft from the corridor at the existing water heater room and extending into 305 B. We would expect this deflection to be a structural issue. Should the structural repair in this area be included as part of our price proposal? The framing members in the area under mechanical room 305B-2 should be replaced with new 2 x 6’s at 16” on center and new floor sheathing.

10. The existing firewall in the corridor between 305A and 305B has existing abandoned pen-etrations that open the attic space between the corridor and 305A and 305B. Are these are-as to be repaired as part of this contract? Any abandoned openings either existing or new-ly caused by systems removal will need to be repaired with type X drywall on both sides.

Any small gaps may be filled with Fire rated intumescent caulk.

11. The Lektreiver units are to be supplied and installed by the VA. In drawing S1.2, 305 B:

First floor framing plan notes: “ See Architect and Manufacturer for support points. Plans call for the installation of new CMU foundation walls under these points. Is there addi-tional structural support required by the Manufacturer? The structural supports indicated on the plans are based upon Lektreiver supplied information for storage units which match the existing units the agency has now. If the storage system that the VA ultimately selects changes from that used for the “Basis of Design” assumed for the construction docu-ments, then the supporting points may need to be revised. For the sake of bidding assume that the supports shown on the plans will suffice.

12. Please confirm that all Telco Fiber pull points are located in 307B. Correct.

18. Per Drwg EP-2 tap is to be made to Bldg. 307. Please clarify if the new conduit is to be in-stalled within the underground access tunnel or if a conduit is to be installed in a new trench. The design intent is for the tap to be made at a junction box along the path of the existing feeder as described in the one line diagram on sheet EP-2. The feeder tap run from that point will follow same path as the existing feeder until separating to feed the new panel 305B. A separate trench is not envisioned
