78 1. What is the extent of ceramic tile on the finish schedule?

Per sheet A-602, the ceramic tile is on the backsplash of the pantries. Tile in vestibules of bathrooms 29-217 and 29-221 must match adjacent, existing tile.

1) There are no specs for signage but there is some for glass film under the partitions section. So from what I can glean from the drawings is that the private offices (and a handful of conference rooms) get the room info in vinyl only (sign type 2) in combination with the Fasara privacy film, and the balance of the rooms (where indicated) get a sign type 1. Is that correct?

All glass office fronts (offices, conference rooms, etc) receive the distraction band film per elevatioin 5/A-603 and the film specifications.

The signage plans indicate which rooms receive which signage type

80 2) My concern is that this setup is not code compliant.

The tenant is the authority having jurisdiction and has approved this layout.

3) It is not clear to me which if any other rooms are glass front and get the distraction graphics as well. I don’t see it on the finish details and the only one called out specifically in the elevations is the break room on Floor 23 (see drawing 2, A-603). Problem is that room is supposed to get a sign type 1 which can’t be mounted on glass. Drawing 6,A-602 calls out a pantry wall on Flr 27 but there is no pantry, just a break room, so I’m operating on the assumption that that is what is intended.

This RFI is generating reduntant information that is contained in the documents. All glass office fronts (offices, conference rooms, etc) receive the distraction band film per elevatioin 5/A-603 and the film specifications. Drawing 6/A-602 is an elevation in room 27-163, as indicated on sheet A-127. Per the room signage schedule, room 27-163 is to receive sign type 02.

As per keyed note S6A on drawings E-124, we are to provide panel RP-CP. This note is shown in room 24-113 and room 24-132.

Please confirm that panel RP-CP referenced by this note is actually panel RP24SCIF-A shown in room 24-113 and panel RP-24SCIF-B (sect I & II) in room 24-132.

Yes. Panel names were revised as per GSA reviewer request. E- 124 has been reissued for clarification.

Re: Mechanical Demolition-Sheets M-123.00, M-124.00, M-

127.00 and M-129.00 do not provide any indication on the extent of mechanical demolition in the areas to be work in.

What is to be demolished with regard to mechanical systems in the work areas?

As indicated on the drawings, where identified, all ductwork is to be demolished and removed back to the point of connection. It is recommended that the contractor assume 3 pounds of sheetmetal per SF. It is not anticipated that there is any large equipment located above the ceiling.

Re: Louvers-Plan sheet M224.0 has two new louvers shown on column line J labelled ‘By Others’. Specification 233113 paragraph 3.1.NN has that ‘louvers in Building Façade… will be provided as part of the work of another contractor’ and the specifications provide no requirements for exterior louvers under this contract. Plan sheet M-603 provides an exterior louver detail. Are exterior louvers to be provided under this contract, and if so, what are the requirements for those louvers?

Louvers are existing and should be assumed to provide adequate open area for the equipment shown.

Re: Mechanical Work for Options 1 and 2Plan sheet M223 shows ductwork for supply that crosses the boundary between areas A and B at several locations, and sheet M324 shows piping supplying units in area B being supplied across area A. For example if only option 1 is taken the supply ductwork for rooms 2304, 2305, and 2306 would not be connected. If only option 1 is taken what changes are required for the piping and ductwork at the boundary between area A and area B?

These room numbers are in the annex side of the building and have no relationship to Option B.

Therefore, if Option B happens and not A there would be no impact to HVAC for these rooms.

Re: Wall at Area A and B Boundary-Is the wall between areas A and B to be assumed to be constructed under both options 1 and 2? The wall should be constructed under Area B.

Re: Fire Watch-Is a 24 hour fire watch required in the construction areas when the fire sprinkler service in that area when the sprinkler is inactive in the construction area?

Re: Wall Type A6C:Wall type A6C is provided on the partition schedule on sheet A702 which shows installation of foil and new gypsum wallboard on existing exterior walls at the windows in secure areas. Plan sheets A123.00 and A124.00 do not call out this wall type to be installed and have it noted that the insulation behind the induction units is not to be disturbed. In addition, sheets M123.00 and M124.00 call for those existing induction units to remain in place which would prohibit the installation of wall type A6C at those locations.

Induction units are to remain and not be touched in these locations. The induction unit will act as the foil in the wall, so foil does not need to be added to the wall where the induction unit is located, only in the portion of the wall above.

Re: Wall type A6C: Where is wall type A6C to be installed?

Wall type A6C indicates existing walls at the perimeter of room 14/SWE spaces. This drawing indicates where the new RF film is to be located with keynote 7
