NIGP 913: Construction Services, Heavy, Including Maintenance and Repair Services

NIGP 913 Construction Services, Heavy, Including Maintenance and Repair Services is a Class code covering the heavy construction and infrastructure maintenance work that state and local governments solicit regularly—water and wastewater line extensions, bridge and retaining wall replacement, stormwater management, utility relocation, parking structure construction, and facility renovations. Recent solicitations show a mix of issuing bodies: cities (Midland, Santa Cruz, Houston, Beaverton, Wichita, York, Gallup), counties (San Mateo, Harris, Orange, Sacramento, Greenville, Collier, Delaware), a state agency (Delaware Division of Facilities Management), school districts (William S. Hart Union High School District), tribal governments (Gila River Indian Community), and transit authorities (Collier County Board of County Commissioners). Repeat buyers across the sample include Harris County (multiple precincts issuing drainage, roadway, and signal work), Orange County Public Works (multiple job order contracts for construction management and roofing), and Delaware's Office of Management and Budget (legislative facility renovation, minor capital projects statewide). Work under the code spans new infrastructure build-out, replacement of aging systems, modernization of existing facilities, and green infrastructure integration (bioretention, rain gardens, stormwater controls).

Geographic activity concentrates in Texas (Midland, Houston, Harris County, Wichita), California (Santa Cruz, Orange County, Sacramento, Beaverton), Pennsylvania (multiple municipalities and townships), Delaware, and the broader Mid-Atlantic and Southwest regions. Representative recent solicitations include the City of Midland's Utility Extension Program 07 (sealed bids due August 6, 2026, $2 million contract ceiling for water, wastewater, and pavement work over 2026–2029); San Mateo County's Entrada Way Culvert Slip-Out Bank Stabilization Project (sealed bids due July 23, 2026, $2.249 million engineer's estimate for creek channel and roadway stabilization); and the City of Beaverton's SW Juniper Terrace Waterline Improvements (IFB due July 21, 2026, $1.2–$1.3 million estimated cost for 3,500 feet of water main replacement). Prevailing wage requirements, performance and payment bonds at 100 percent of contract value, and local-vendor preferences appear consistently across solicitations. Set-asides for MBE/WBE, DBE, and SBE participation are present in select procurements, particularly those receiving federal or state grant funding (FEMA, DWSRF, WIFIA, CDBG, Davis-Bacon-covered work). No single vendor dominates the opportunities; competitive sealed bidding and RFP processes dominate the market. Activity is steady and diversified across project types and jurisdictions.
