Solicitation #36C77623B0064 - EHRM San Antonio Infrastructure Upgrades Prospective Bidders’ Questions and Government’s Response to The Questions

Q2: Please confirm Section 13 05 41 Seismic Restraint Requirements for Nonstructural Components does not apply for this project in San Antonio’s seismic zone of Zero (g=0.0).

A2: Confirmed.

Q3: Please confirm if the QC Manager has sole duties and cannot share duties as Superintendent.

A3: Confirmed. The QC manager shall have sole duties and cannot share duties as Superintendent.

Q4: Plan GI005 Construction Safety Note 1 calls for temporary construction barriers of 1 hr fire rated gypsum wall to bottom of chord of truss or to junior beams with rated poly barrier to deck.

There are many MEP systems in this facility running below the junior beams, making temporary drywall partitions difficult. Instead, can the poly rated barriers be used from ceiling height to deck?

A4: Poly rated barriers are acceptable from ceiling height to deck.

Q5: Demotion Legend (typical) AD 406 show Temporary Construction Barrier references F5/AE523. Where is Sheet 523 and the detail F5?

A5: Reference should be to F1/AE551.

Q6: Detail F1/AE551 shows a construction barrier wall. Is insulation required in these temporary walls? Type?

A6: See reply to Q5. Yes, these walls will require acoustical insulation, unfaced mineral fiber batts or blankets, ASTM 665, Flame Spread Rating: 25, Smoke Developed Rating: 450.

Q7: Sheet Note 4/AE108 tells bidders to assume the roof is asbestos. Is this correct. There is no section 02 82 13.21 Asbestos Roofing Abatement referred to in Note 4.

A7: SECTION 02 82 13.21 will be provided by addendum.

Q8: The performance period of 365 days is insufficient. Request the performance period be changed to 720 days.

A8: The SOW allows for 18 months (545 calendar days) due to long lead times.

Q9: What is the specification or basis of design for the Waterproofing sheet Keynote W18 on Plan AE521?

A9: Rubber type sheet formed of non-reinforced, homogeneous, impermeable, sheeting compound reduced to thermoplastic state, resistant to fungus, mildew and bacteria, not less than 1.5 mm (60 mils) thick. Install per manufacturer’s instructions.

Q10: Please provide make, model and colors of existing wall protection and railing to match per Keynote W21 on Plan AE521.

A10: Please disregard this note, as there is no wall protection and railing installation anticipated. If any requires removal, it should be salvaged for reinstallation.

Q11: Where would the concrete pad at Condensing Units apply (see D3/AE551)? Not on the roof???

A11: Refer to Sheets MN-100 for location of split system condensing unit that are install at grade; this detail would apply to those.

Q12: Attachment 1(c) Drawings – Mechanical and Attachment 6 Mechanical Cut Sheets are the same file when opened. Is this intended?

A12: This was not intended. The correction has been made, and the correct Mechanical Cut Sheets have been uploaded to SAM.gov, and the duplicate incorrect file was deleted.

Q13: TY401 typical General Note 6 refers to CCTV system conduit rough-in, but no CCTV system is shown or specified. Is Note 4 Not Applicable?

A13: New cameras in TR's and Datacenter (as shown on plans) to be connected to existing Base Building CCTV system. Rough-in for cameras to be by electrical contractor per note #6.

Q14: TY401 typical Vendor Contact Information Note refers to locations of security cabinets by others with no locations. Where should we assume the cabinets are located? Without some more specific information, the scope of work is indeterminate and cannot be included in bids.

A14: New security system project was on-going at time of design. VA to provide update on new security installation and provide as-builts showing head-end equipment locations. For bid purposes, assume 300 ft cable run length from camera to security switch.

Q15: TY401 General Note 3 (typical) refers to shop drawings by “Base Security System Vendor”. Confirm this vendor and his shop drawings are Not In Contract.

A15: Security system work is to be performed by security system contractor (vendor) under contract for the medical facility campus. Security system should not be modified by Division 27 contractor without involvement from the base building security contractor.

Q16: MN 424 shows Fire Suppression (Clean Agent and Wet Systems) in Data Center Room I100.2. What fire protection is intended for New IT Operations I100.1 and Office I100.1B?

A16: There is existing sprinkler coverage in the old data center/new IT office area that should be revised as necessary to provide sprinkler coverage for the new IT offices per NFPA 13.

Q17: Mech plans use symbol “FP” see MN 406 and pipe on MN411 are typical. What is intended by FP?

A17: FP is Fire Protection and indicates sprinkler piping.

Q18: Fire Protection Note 12 Sheet M000 calls for paint on exposed Fire Protection Pipe?????

A18: Yes.

Q19: Wall Types Sheet AE521 Note 10 states that if a wall type is not shown, assume wall type

10. There are several wall type 10. Which is intended Wall Type F1D or F1A?

A19: Use F1D where there is an interstital deck above and F1A elsewhere.

Q20: Wall Types Sheet AE521 Wall Type 10 F1G. There is an Interstitial Floor Deck only in the newer G wing of the hospital. Most areas have an open Interstitial space above the ceiling.

Please confirm Wall Type 10 F1G wall terminates at the bottom of truss or junior beams with sheetrock 6” above ceiling.

A20: Coordinate with room sections on sheets AE351 through AE355. Gypsum wallboard can terminate at hardlid in TR and 6" above t-bar ceiling at adjacent spaces.

Q21: F1/AE551 One Hour Construction Barrier shows a metal stud wall with insulation and sheetrock on both sides extending above the existing wall. Installing sheetrock above occupied spaces with acoustic lay-in ceilings is unnecessarily expensive and potentially disruptive to the occupants. Can fire rated poly barrier be used above existing walls for the Construction Barrier?

A21: Fire rated poly barriers are acceptable above existing walls and ceilings.

Q22: C5/AD403 Note D01 in Room C132 shows floor under racks to remain. C3/AE403 Room c132 Note A24 calls for new SDT flooring. Is this new floor just around old floor to remain?

Q27: Please confirm fire sprinkler protection is not required above the data center ceilings.

A27: Sprinkler coverage above the data center ceilings is not expected to be necessary.

Q28: Confirm storm drain piping indicated to be demolished on sheet MD400, is abandoned storm drain and not in service.

A28: Confirmed.

Q29: Where new cat-6a cabling is required to replace existing cabling, please confirm there is existing in-wall conduit and backbox to be re-used. If any new in-wall conduit and associated wall patching is required, please clarify locations this will be required.

A29: Data outlets labeled "C#-E" will keep their existing backbox and conduit, while data outlets labeled "C#" will require a new backbox and new conduit. See room A304.9 on sheet TN166 as an example of an outlet that requires a new backbox and conduit. It is the responsibility of the contractor to verify the locations and quantities of all data cabling.

Q30: What is the “Owner Provided Equipment” on the horizontal copper diagrams of each TR?

See TN430 for example.

A30: This is equipment provided and installed by the VA.

Q31: Is phasing required between the existing and new data centers? If phasing is required, will the new data center be required to be in service prior to work being able to start in the existing data center to convert it into the IT offices space? If so, how much time will the VA require to move into the new data center?

A31: The datacenter must remain operational at all times. This will require phasing. It is the responsibility of the contractor to develop the phasing plan for the cut over from old to new datacenter. It is anticipated that IT staff will be housed in a temporary trailer provided by the contractor for the duration of construction activity in the datacenter/new IT office areas.
