About this file
This document is a Requests for Information (RFI) and Responses record for federal solicitation W50S8R-26-B-A002, dated July 24, 2026. The RFI compiles thirteen inquiries from potential contractors and corresponding government responses addressing clarifications related to the contract scope, technical specifications, environmental conditions, and administrative procedures.
The project involves demolition of Building 414 and construction of an approximately 170 feet by 180 feet aggregate parking pad with geotextile base, along with HVAC equipment replacement and controls system integration at Building 522. Environmental conditions include confirmed asbestos presence requiring wet demolition and certified Construction and Demolition Debris (CDD) landfill disposal, plus assumed lead-based paint throughout Building 414 due to the structure's age, with no further hazard investigation or remediation required. Specification clarifications address geotextile allowance dependent on contractor means and methods, parking pad thickness and compaction requirements referenced in Statement of Work paragraphs 2.5.5 and 2.5.6, and demolition during aggregate placement. For the HVAC and controls work, the existing system uses General Vykon Workstation with INTRO CIM Graphic Platform and JACE Controllers; contractors are responsible for all system integration and commissioning of newly installed equipment only, with electrical service confirmed at 208/60A. Contractor requirements include wet demolition of Building 414, obtaining base access clearances for all personnel, scheduling planned outages seven days in advance with government coordination, and keeping outages to a minimum. Contract time adjustment is available if government-approved HVAC equipment cannot be obtained within the specified period due to manufacturer delays. Hand-delivered bids are considered timely if received at the bid repository prior to 1:00 PM EST on the bid deadline, and the repository remains available for submissions through the deadline.

Requests for Information (RFI’s) and Responses – Solicitation #: W50S8R-26-B-A002
(as of 24 Jul 26_Final)
RFI 01
- Has a hazardous materials survey and report been done on B414?
RESPONSE: There are no hazardous materials currently located in Building 414.
With regards to lead-based paint (LBP), the contractors will need to assume that LBP is present due to the age of the structure. No survey has ever been done but the assumption is that LBP is present.
With regards to asbestos below is the information we have on file in our Asbestos Management Plan. With the boiler issues resolved in a previous replacement project.
RFI 02
- Do you have a current controls contractor that manages Building 522
RESPONSE: the Government is not authorized to provide suggested sources of services or supplies, unless an exception applies (brand-name/sole source supported by an official justification). DDC (controls) services are not brand-name/sole source services.
RFI 03
Section Para
Question
31 00 00 1.6 Is a Geotechnical Engineer needed? This spec appears to be for new construction, please clarify what portions the Govt wants to utilize for this project.
RESPONSE: paragraph 1.6 of this section is omitted (revised specification attached)
31 32 19.16
1.1 “Allowance will be made for geotextile in anchor and/or drainage trenches” Please provide Geotextile allowance.
RESPONSE: paragraph 1.1. of this section is revised. This is dependent on contractors means and methods for install. Bid what is needed to properly install beneath an approximate 170’x180’ aggregate parking pad.
31 32 19.16
1.2 “Geotextile installed and accepted will be paid for at the respective contract unit price in the bidding schedule.” Please provide the bidding schedule.
RESPONSE: paragraph 1.2 of this section is revised. The materials related to completing this project are not separately lined out in the contract bidding schedule (CLIN’s/line items). The pricing for these materials, as well as any other materials, services, and costs related to accomplishing CLIN 0002, are to be included in the contract CLIN price.
32 15 00 1.6 This spec appears to be for new construction, please clarify what portions the Govt wants to utilize for this project.
RESPONSE: For the site restoration and construction of the aggregate pad
32 15 00 2.3 This spec appears to be for new construction, please clarify what portions the Govt wants to utilize for this project.
RESPONSE: For the site restoration and construction of the aggregate pad
32 15 00 3.6 “Compact the completed aggregate surface course to the thickness indicated.” It is assumed this is for the proposed parking lot area, please provide thickness.
RESPONSE: See Statement of Work, paragraphs 2.5.5 and 2.5.6
32 15 00 3.11 This spec appears to be for new construction, please clarify what portions the Govt wants to utilize for this project.
RESPONSE: During placement of aggregate

RESPONSE: paragraphs 3.6 and 3.7
RFI 04
Page Section Para
Question
11x17 Plan Sheet
Demo Plan
The assumption is that the existing hard surface areas will be parking lot, and the existing grass areas will remain. Please clarify.
RESPONSE: Some grass areas will be encountered constructing the 170x180 aggregate pad
31 32 19.16
It is assumed that most of the proposed parking lot area is well established and stabilized. Please clarify where the Govt wants to utilize this spec.
RESPONSE: Yes we want the entire base of aggregate pad constructed over geotextile
11x17 Plan Sheet
Parking Lot Area Plan
Please provide specific location and elevation detail of the proposed Geotextile
RESPONSE: Finish surface should match existing elevation and be graded to drain as described in the statement of work
RFI 05
1. Has a Complete Survey been done on B414? EPA requires the name and ID# of person who performed.
RESPONSE: A complete survey has not been conducted. We know through previous testing that there is still asbestos present in the building, and we can assume that there is still lead-based paint somewhere in the building due to the age of the structure.
2. What hazard study does the Govt want done? Phase I or Phase II?
RESPONSE: Both asbestos and lead-based paint can be received by a certified Construction and Demolition Debris (CDD) accepting landfill. There is no need for any further hazard investigation or remediation of B414. As long as the contractor performs a wet demolition of B414 to prevent asbestos fibers from getting airborne, and they send all debris to a certified CDD landfill, no other environmental requirements need to be met for this project. See revised paragraphs 2.2.1. and 2.2.2. in attached revised statement of work.
RFI 06
- Please advise who the Base Controls Contractor is.
RESPONSE: See response to RFI 02 above.
RFI 07
1. The specifications require integration into the existing DDC system but do not clearly identify the existing controls manufacturer or required programming scope.
Please identify the existing DDC manufacturer, software platform, licensing requirements, and whether the Government will provide programming access or if all integration shall be by the contractor.
RESPONSE: General Vykon Workstation, INTRO CIM Graphic Platform, JACE Controllers. Contractor is responsible for all integration; however, if there is issues with contractor access, the Government will assist getting contractor proper access in order to be able to complete integration.
2. Please confirm the existing electrical service and feeder capacities are sufficient for the new equipment. If upgrades are required, will they be handled by change order?
RESPONSE: Yes, current unit is fed by 208/60A circuit, see drawings.
