Repair Condensate Pipe Pier XRS

Air Mobility Command (628 Civil Engineer Squadron, Joint Base Charleston-Weapons Station) intends to solicit a total small business set-aside contract for repair and seismic bracing of a three-inch condensate line at Pier X-Ray South, with a response deadline of September 4, 2026 and anticipated award by September 30, 2026.

Work is performed at Joint Base Charleston-Weapons Station, Goose Creek, South Carolina, on the Naval Petroleum Transfer Unit (NPTU) property under a riverine environment adjacent to the Cooper River. The Naval Reactors facility is subject to Executive Order 12344 and requires security access processing at least five business days in advance; restricted items including personal electronic devices, cameras, and cell phones are prohibited within NPTU's security enclosure.

The contractor shall remove a non-essential low point drain valve from the condensate line, cut and remove approximately one foot of pipe on both sides of the tee, replace galvanized supports with stainless-steel hanger rods using Hilti HIT HY 150 MAX-SD adhesive anchoring, install eight new seismic braces (four longitudinal and four transverse in one-inch pipe size using 316 stainless steel), and replace approximately three feet of the line with three-inch schedule 80 seamless carbon steel ASTM A106-Grade B pipe. All welding shall be performed by qualified welders per ASME BPVC Section IX with independent inspection; a thirty-minute hydrostatic test is required with NPTU witnessing. Heat trace cable repair, protective inorganic silicate zinc coating (PPG Dimetcote 9 VOC or equivalent), and new T-3 cellular elastomer pipe insulation with 304 stainless-steel jacketing shall be installed.

All work must comply with International Building Code, International Mechanical Code, International Plumbing Code, American Welding Society, National Electrical Code, National Fire Code, Base Architectural Compatibility Guide, Unified Federal Criteria, and Unified Facilities Guide Specifications. Environmental compliance requires allowing 30–60 minutes for aquatic animal vacation before high-intensity activities, quieter or vibration-dampened equipment where feasible, and real-time environmental monitoring during initial setup and high-noise phases. Contractors must provide a Plan of Action to NPTU at least ten days prior to work start, coordinate daily with the Site Work Controls Officer, and suspend work 72 hours before severe inclement weather landfall. The Government intends to award a single Firm-Fixed-Price contract. A mandatory site visit will occur within an estimated three calendar days of solicitation issuance.
