Answer: Phasing to be coordinated with COR.

RFI via email 8/31/2020

Answer: Ceiling gasketing 1/4-inch x 1/8 inch open cell foam tape shall be precut to the exact size and installed in continuous pieces (corner to corner) and in straight lines along existing ceiling grid flange. Apply gasket to the backside (horizontal edge) of the tees Apply foam tape continuously at each flange of the grid system, overlapping in corners if necessary.

Answer: Infill gaps between the wall and the cabinets with backer rod (07 92 00 -2.3) and provide continuous sealant per specification 07 92 00 to create an air tight seal.

Answer: No finishes are required for this work. Contractor to cap the existing pipes flush with the wall and floor once fixture is removed

Answer: The intent is to match existing. Existing finish is Birch veneer rotary cut “RA100” by Algoma Hardwoods

Answer: VA Cincinnati existing lockset and keying is Corbin Russwin (see attached J & A)

Answer: 98% of the roofs are BUR Tremco Roofs. There is no active roof warranty for the work on building 1 except for the ambulatory care tower. The intent is to maintain roof integrity.

Answer: The only upgrade to existing building structure that is required is for new duplex plume fan 1-DPF1. Structural steel drawing for this is Sheet S101.

Answer: It is unclear which fan(s) this question is referring to. QuickFrames are not acceptable for support of 1-DPF1, which shall comply with Sheet S101. If this is referring to other fans, please specify fan(s) in question.

Answer: All work in occupied areas of the building that blocks normal traffic flows or disturbs normal business in the hospital by shutting down active systems or creating excessive noise or dust, shall be performed at night or on weekends. The exception is Inpatient areas of the building, which need to be performed during the day, so as not to disturb sleeping patients at night. Inpatient areas are as follows: Rooms A501-A528, A5083-A5100, A600-A631, A647-A675, A704-A726. All work above 9th floor ceiling west of the main elevator bank shall be scheduled with COR well in advance, to avoid disturbing daytime sleep studies.

Answer: Survey was conducted, and hazardous materials are present requiring abatement as part of this project, per General Note #25 on Sheet M001. Refer to spec 02 82 11 for estimated quantities, locations, and type.

Answer: No

Answer: It is unclear whether the 5 outlets all need to be in the same location, whether they all need to be on different circuits, etc. There should be plenty of 20-amp outlets throughout the building.

Answer: This duct does not need to be welded. The duct is located near the slab in a location that is traveled frequently, so the existing duct is crushed. The new duct is not running 10” wc but is specified as heavy gauge to protect it from similar physical damage in the future.

Answer: Strobic for 1-DPF1; Greenheck for all others.

Answer: One existing framed gyp wall will be removed to install this fan, and fan type has been revised to fit through other existing door openings – refer to Addendum #2.

Answer: Infill shall match existing construction, per the note on the drawings – contractor to field verify existing construction. The exterior side of the wall at this location is brick.

Answer: It is unclear which exhaust fan/system this question is referring to. All new fans shall be balanced, which includes rebalancing of the entire system (fan, ducts, air devices/exhaust terminals, hoods, etc.). There are many exhaust fans that are existing to remain with no work under this project, included in the drawing set for reference only, that do not require rebalancing.

Answer: Yes.

Answer: Infill shall match existing construction, per the note on the drawings – contractor to field verify existing construction. The exterior side of the wall at this location is brick.

Answer: This information is shown in the fan schedule on Sheet M601.

Answer: Total existing leakage is unknown. Leakage requirement for the sealed ducts shall be less than 1% of rated airflow, which has been achieved for multiple systems at this campus via Aeroseal in the past.

Answer: Yes – refer to Addendum #2 for listing of hoods.

Answer: GC will coordinate with COR for staging area inside the VA campus (see attachment drawing – this area is subject to change)

RFI - EMAIL RECEIVED 9/14/2020

Refer to the noting on the drawings – any work on this project that is required above hard ceilings, a new access panel was added to accomplish the work, which is clear on the drawings. Other rooms with hard ceilings (typically very small closets that had exhaust air that is being removed), we avoided working above the ceiling in these spaces by capping ducts at walls & ceilings and abandoning duct above the hard ceiling – this is also clearly noted and shown on the drawings.
