NIGP 91842: Engineering Consulting

NIGP 91842 Engineering Consulting is an Item code encompassing the full range of professional engineering design, environmental compliance, permitting, construction administration, inspection, and project management services that state and local governments actually procure—from transportation infrastructure and water systems to facility rehabilitation, coastal resilience planning, and specialized technical analysis. Recent solicitations show municipalities, counties, transit authorities, state agencies, and special-purpose districts (airports, utility authorities, water reclamation facilities) engaging firms across disciplines including civil, structural, mechanical, electrical, geotechnical, environmental, marine, and architectural engineering, often combined with survey, landscape, and cost-estimating work. State and local agencies are actively soliciting design services for roadway and intersection improvements, wastewater and water-supply infrastructure, drainage and stormwater management, terminal and facility expansions, disaster recovery and resilience improvements, and ongoing on-call general engineering support. Issuing bodies span the full spectrum: state departments of transportation and energy; county toll authorities, water departments, and commissioners; cities ranging from mid-sized to major metropolitan areas; transit authorities; airport authorities; and water reclamation facilities. Repeat buyers include the City of Phoenix (multiple large infrastructure contracts), Georgia Department of Transportation, Harris County Toll Road Authority, and Florida municipal utilities and county governments. Geographic activity is distributed across the Southeast (Florida, Georgia, South Carolina), Southwest (Arizona, New Mexico, Colorado), and isolated activity in the Northeast and Pacific states, with no single region dominating recent solicitation volume.

Representative recent opportunities include Georgia Department of Transportation's RFQ 484-081726 for Construction Engineering and Inspection services on three state highway intersection projects in Barrow County (due August 17, 2026, IFB structure with shortlisting and negotiation), Harris County Toll Road Authority's RFSQ 260165 for system-wide inspection and condition assessments of roadway, bridge, and facility infrastructure across its toll road network (due August 17, 2026, multiple-award structure), City of Palo Alto's RFP 198186 for a Water System Master Plan with mandatory pre-proposal conference attendance (due August 7, 2026, fixed-fee not-to-exceed structure), City of Tolleson, Arizona's on-call general engineering services RFQ covering seven disciplines with purchase-order caps of $500,000 per task and $2 million aggregate per firm annually (due August 19, 2026, time-and-materials on-call model), Sacramento County Department of Airports' RFP for facilities condition assessment and asset management services across four airports with ProDIGIQ system integration (due September 8, 2026, single-award three-year initial term), and multiple construction engineering and inspection awards for roadway corridor projects in Florida counties. On-call and master-services frameworks predominate in urban areas; qualification-based selection with subsequent fee negotiation is standard; and federal funding (FAA grants, FEMA disaster recovery, CDBG, state revolving funds) drives compliance requirements including prevailing wage, DBE participation, E-Verify, and Build America, Buy America provisions across many opportunities.
