NIGP 91185: Special Trade Constructon, Power Plant

NIGP 91185 Special Trade Construction, Power Plant, is an Item code under which state and local governments procure specialized construction services for detention facilities, corrections infrastructure, water treatment facilities, and utility systems—work that falls outside standard general contracting but requires focused expertise in confined spaces, security systems, and mission-critical infrastructure. Recent solicitations show Orange County, Florida and the City of Detroit driving activity, with Orange County issuing multiple large-dollar bids for corrections facility upgrades and bridge replacements, while Detroit focuses on detention-center janitorial services and facility maintenance. The work spans security-control installations, bridge replacement, cell renovations with complete piping replacement, utility relocation, water-system expansion, and low-pressure sewer installation—reflecting a mix of emergency infrastructure repair, facility modernization, and specialized systems integration in corrections and municipal water environments.

Orange County, Florida has been the most active recent issuer under this code, posting sealed bids for Wallington Drive and Egret Way Bridge Replacements (estimated $6.2 million, due July 7, 2026, ITB Y26742); Female Detention Center cell renovations and domestic water piping replacement (estimated $4.1 million, due July 14, 2026, ITB Y25790RC); and Corrections Bureau Reception Center security controls and Building E secure door-and-lock replacement (estimated $7 million, due July 21, 2026, ITB Y26750). The City of Detroit issued an RFQ for janitorial and custodial services at the Detroit Detention Center (due August 14, 2026, RFQ DSS#2), restricted to approved suppliers and requiring on-site labor structured at 34 hours daily across three buildings with security clearances and bonding. Texas municipalities have posted utility relocation and water-system expansion work: the City of Lubbock issued a Request for Proposals for West Lubbock Water System Expansion (estimated $10.5 million, due March 12, 2026, RFP 26-19431-AE) and the City of Cibolo issued an Invitation to Bid for FM1103 Utility Relocation (due June 1, 2026, ITB 26-160-23). The Beaufort-Jasper Water and Sewer Authority in South Carolina solicited an IFB for Alljoy Low Pressure Sewer Phase 1 (due March 24, 2026, IFB 2026IFB020), requiring coordination with SMWBE participation. Geographic concentration centers on Florida and Texas, with secondary activity in Texas municipal water infrastructure, South Carolina sewer systems, and Georgia bridge and facility work. Contracts typically require 100 percent performance and payment bonds, comprehensive liability insurance, and prevailing wage compliance; orange County and Detroit both use electronic-only submission portals (OpenGov and Bonfire). Recent awards favor lowest responsive and responsible bidders; no specific DBE or WBE set-asides are named, though some issuers request HUB certification disclosure or encourage SMWBE participation through good-faith-effort requirements.
