22) The solicitation does not have a pricing schedule incorporated by CLINs. Spec section 01 00 00 1.3 has a statement of bid items; Item 1, Item II, and a bid alternate No.01. Please advise to the structure of this bid. [GD] The bidder shall bid the project with Items 1 & 2 as base bid and separate alternate deducts as indicated in spec section 01 00 00.

23) In addition, the award criteria is not shown in the solicitation. Please let us know if this is an LPTA, low price only and please let us understand the award criteria when evaluating all CLINs.

This procurement is an Invitation for BID. LPTA is the process used for award.

24) Spec Section 01 00 00 1.6 states that temp buildings or storage areas may be erected by contractor. Will the hospital allow our team to utilize the nearest mechanical or penthouse spaces for a limited laydown area for new motors and controls for the project? [GD] The VA will provide construction lay-out space for the Contractor.

25) We see four cars in bank #1 (P3, P4, P5, P6), two in bank #2 (E1, E2) and two in bank #3 (P1, P2) for a total of eight (8) elevators in three different locations. Please provide the constraints for this project in terms of completion. Is this gaining substantial completion or is this a finally accepted elevator by state/USG 3rd party inspectors. Please also confirm if USG will require 3rd party testing at the completion of each phase or if all elevators will have final 3rd party inspection at the completion of all 8 elevators. We want to ensure the correct number of trips for this project. [GD] Each phase will have a substantial completion.

26) There appears to be only 8 cabs included in this project, however, GI104 detail 3/GI104 has S3 and S4 that appear to be out of contract per the electrical drawings (that would make 10 with S3 and S4 inclusion). Please advise. [GD] S3 and S4 is not included in this project. See updated Sheet GI104.

27) The period of performance on this project is 170 days (5.6 months 24 weeks)). From experience on VA elevator projects the procurement process from VA approved submittals can be 12-18 weeks to fabricated and deliver elevator components to site. This leaves 6-12 months to construct the 8 cabs. Please provide an understanding of constraints from RFI #05 and please let us know if the VA would consider extended the POP on this project or if the intent would be to provide a limited notice to proceed for the procurement of material/equipment. P3-6 could take well over the period of performance alone. Please advise. [GD] The Period of Performance shall be 80 week (560 calendar days) for the entire project.

28) Spec Sections 01 45 00, 01 35 26 state the requirements for SSHO, CQC Systems Manager, and CQC Specialists. The contract stays mute about collateral duties for either the (1) superintendent

(2) SSHO (3) CQC Systems Manager. The spec states that the CQC System Manager reports to the Project Superintendent. The spec states that the SSHO has to be independent of the CQC Systems Manager. We know that the SSHO is employed by the prime while Competent Persons (CPs) are employed by the subcontractors. Therefore, the current solicitation calls for three (3) full-time personnel by prime contractor within its field management staff. Please confirm this requirement or please help us understand the collateral duties for each expected member of the team. [GD] These can be the same person within the Prime Contractor.

29) Spec Sections 14 21 00 – 1 and 14 21 00 – 2 show approved vendors under 1.3 quality assurance. Are other notable approved contractors allowed that aren’t on this list, but that have significant past performance and relevant experience. For example, Mid America Elevator was at the site visit but is not on this list. [LB] Mid-American Elevators is approved.

30) Please confirm standard working hours for the project. We have times in GI102 noted. [GD] Refer to response #53.

32) Please describe the reflected ceiling condition of the basement. Does the basement have an open ceiling to deck or is there a hard lid or ACT ceiling? [GD] Lobbies are all hard ceilings – Mechanical Rooms are open.

33) AD101, note 5, states to remove and replace elevator pit ladders. Please provide a detail, pit height, and the 05 specification. Also, please confirm that there are no pit lighting requirements or sump pump requirements. [GD] The sizes of the elevator pit vary from one elevator bank to another. The sizes will have to be field verified. Coordinate with the COR on the requirements for pit lighting and sump pump. Attached please find a standard elevator pit ladder detail, as well as Section 05 50 00 Metal Fabrications.

34) Please confirm patch painting. Patching at the existing patch, or painting seam to seam at the location of all directional indicators and other surface mounted elevator controls. [GD] Walls to be patched and then painted from corner to corner, floor to ceiling.

35) The drawing notes state that Primavera Submittal Exchange must be used. Is this a hard and fast requirement? We have never used this and using it likely means a learning curve. There are other options available like Procore that are more of the standard. [GD] Primavera is likely to be supported, but others must have the same functions and end result as Submittal Exchange and be approved.
