Amendment 2 - Added 22 June 2026 (updated 23 June 2026) - Add Attachment 9 - Amendment 2 - FA441826R0013 Repair Naval Reserve Center B3370 - Prebid Questionay (Complete) AMENDMENT 1 - Added 4 Jun 2026 - Added Attachment 7 - DKGV 1137999 Asbestos Lead Report and Attachment 8 - Sign In Sheet for B3370 Repair Naval Reserve Center Project: Repair Naval Reserve Training Building 3370 Solicitation Number: FA441826R0013 The 628th Contracting Squadron at Joint Base Charleston (JBC), SC is seeking proposals from potential sources for the Repair Naval Reserve Training Facility B3370 at Joint Base Charleston, South Carolina. This project includes the renovation of the Naval Reserve Building 3370 that is used for reserve training 1-2 weekends per month with approximately 250 occupants per weekend. Daily occupancy is about 25 people on a normal usage, and the weekends have high occupancy. The project scope is to replace the HVAC equipment in attempts to eliminate the recent mold growth inside the facility and incidental related work. The humid air has caused the need for temporary de-humidifiers and mold cleanup within the facility. The building currently has numerous HVAC roof top units (RTUs), and the climate control is not working to reduce the high humidity inside the building. A new HVAC system will be designed and any mold or water damaged areas removed, and finishes restored, such as re-painting or replacing ceiling tiles. Cybersecurity is also required for this project Renovation. The renovation shall include providing new HVAC units on the roof and providing any electrical equipment needed to support the new HVAC system, as well as providing duct smoke detectors. A HAZMAT survey was performed to determine the extent of mold that may need to be abated during demolition and refinishing. A plumbing sewer line needs repair at the latrines, to replace it with positive drainage to the existing sewer pump. PRE-PROPOSAL CONFERENCE/SITE VISIT: A pre-proposal conference and site visit is scheduled for 4 June 2026 at 9:00 AM EST.
