Question # Reference

Question Government Response Page Section Paragraph

Can photos of the exterior work areas on the west side of Building 77H please be provided? The Government did not grant access to this area during the pre-bid site walk.

Pictures cannot be provided due to content and the level of review required.

Can photos of the interior (high bay area and lean-to) column lines 1-12 of Bldg

77H be provided? Photos of the existing condition would be useful to bidding subcontractors unable to attend the pre-bid visit.

Pictures cannot be provided due to content and the level of review required.

Has the exisiting roof steel in Building

77H, and other any other existing steel locations, been analyzed as adequate to support suspended scaffolding? Or alternatively, please provide the hanging load capacity of the roof structure.

No. Temporary loading is the responsibility of the contractor. See Structural sheets for load information.

67 2PD401

Please clarify access points to the Fuel

Oil Purifier Room as there are no doors shown on the drawings. This could affect if/how the equipment required to be removed from this room can be removed in whole or needs to be done in parts and/or if an opening needs to be created in a wall. If the designer has an intent please indicate.

The lines that appear to be enclosing the existing fuel oil purifier represent an 8" concrete curb, not wall. There should be no issue with the removal or replacement of equipment in this space.

Can someone confirm the exact location of the existing Lenel ACP Intelligent

Control Panel with the Star Multiplexer

(LNL-8000) that the Control House new

Card Reader Modules (LNL-1320) will connect to via a RS-485 (2-wire)? Does the Security Contractor need to confirm that the existing ACP and Star

Multiplexer has the capacity for the additional LNL 1320 Dual Reader

Modules?

Refer to 2TY101 for location of existing Lenel ACP with

Star Multiplexer. It is WRA's understanding that the lenel panel has capacity to incorporate Control House

Lenel Dual Reader Interface

Modules.

Regarding the CRAC units on drawing

2M604 detail C1, there are packaged controls included. However, some points are marked in the schedule of this detail without 'Note 1' which states: "Obtain input through a BACnet connection to packaged unit controller." Are the points marked without 'Note 1' to be controlled directly by the Controls Subcontractor?

The points that are referenced with Note 1 are analog and digital inputs for monitoring only. There are no controls commands associated with these points.

98 2M606

Eaton Crouse-Hinds appears to have a series of panelboards rated for the proposed hazardous location with ratings available up to a 600A main bus.

108 1C107 Key notes

24, 25.

Both of these notes indicate scope by the

Utility Provider (assumed to be

Dominion) but the notes and details refered to are silent as to the extent of scope by the Utility. This typically depends upon the scope of a contract between NAVFAC and Dominion. Is that scope finalized and can the scope be provided? If not, for bid purposes please provide the detailed scope that Dominion will provide. For example, ktr build ductbanks and pull cable and Dominion will make terminations, ktr build pad, install switch, Dominion will furnish the switch and make terminations, or some variation thereof.

The Utility Provider will provide the switch, concrete pad, ductbank, wiring, excavation, trench repair/site restoration, etc. associated with installation and connectivity at and upstream of the 6-way switch. This project will provide all work downstream of the switch.

For bidding and schedule purposes, how much time should be alloted for the

Government's provision of the Air

Permit for the temporary fire pump?

"Refer to specification 21 30

00 paragraph 2.3.3. ""The installation permit application process will take up to five (5) months and begins when the

Government has all information necessary from the Contractor to build and submit the permit.”

Please provide bid quantity for concrete ceiling patching after sprinkler demolition.

For keynote #2 on 2FD107, assume for bidding purposes there are 8 locations that require patching and each location is approximately 4" diameter and 10" thick.

111 2P302

Fuel Tank room - Section C3/2P302 appears to indicate that the Fuel Tank room is sitting on support beams of some sort. There is no indication of this on the structural drawings. Please clarify.

W4x13# support beams are specified to be provided with the tank in 33 56 10, Paragraph 2.4.1.g.7.
