NIGP 305: Engineering and Architectural Equipment, Surveying Equipment, Drawing Instruments, and Supplies

NIGP 305 Engineering and Architectural Equipment, Surveying Equipment, Drawing Instruments, and Supplies, a Class code, encompasses the full spectrum of design, engineering, and surveying services that state and local governments procure to plan, document, and oversee infrastructure, facilities, and environmental projects. Rather than reflecting commodity purchases of instruments and supplies alone, recent solicitations show this code capturing professional engineering and architectural consulting across multiple disciplines—civil, structural, mechanical, electrical, geotechnical, and environmental—delivered as on-call frameworks, task-order agreements, and project-specific engagements. State and local issuers span counties (Sacramento, Harris, Broward, Seminole, Pasco, Lee), cities (Pompano Beach, Arlington, Meriden, Bradenton, Rio Rancho, Benson, Orange County), school districts (Northwest Community Schools, Meriden Public School District), transit and water authorities (South Florida Regional Transportation Authority, West Basin Municipal Water District, Great Lakes Water Authority), and special districts (Brazos River Authority, Harris County Toll Road Authority, Harris County Flood Control District). Representative recent work includes the City of Pompano Beach's RLI for construction engineering and inspection services on the SR A1A Improvements Project (responses due November 10, 2026); the County of Sacramento's RFQ for construction manager at-risk services on the Sacramento International Airport Airfield Maintenance Facility (due December 1, 2026 for SOQs); Collier County's RPS for professional design services on Lake Park Boulevard improvements and flow-way restoration (due November 10, 2026); and the City of Meriden's RFQ/P for architectural and engineering services on a new elementary school (due October 22, 2026).

Activity concentrates heavily in Florida (Orange County, Broward County, Collier County, Lee County, Pasco County, Seminole County, and Palm Bay) and California (Sacramento County, West Basin in Los Angeles County), with secondary clusters in Arizona, Texas, Connecticut, and Oregon. Florida jurisdictions alone post concurrent work spanning airport facilities, convention center retrofits, water reclamation plants, transit network redesign, parking structures, and school construction. Procurement instruments are dominated by RFQ and RFP structures for on-call and continuing-services frameworks, reflecting state and local preference for establishing pre-qualified vendor pools and issuing task orders as projects materialize. Evaluation criteria emphasize relevant project experience, key personnel qualifications, past performance with similar scope, technical approach, and—in federally funded work—compliance with prevailing wage, Buy America, Davis-Bacon, and DBE participation requirements. Insurance requirements are consistently substantial: professional liability ranging from $1 million to $2 million per occurrence, general liability at $1 million to $5 million per occurrence, and workers' compensation at statutory minimums or higher. Compensation structures vary by project phase and delivery method, from lump-sum fixed fees in design-bid-build delivery to time-and-materials hourly rates for on-call services and guaranteed maximum price arrangements under construction-manager-at-risk delivery. The code sees active pursuit across the contract lifecycle—planning, design, permitting, construction administration, commissioning, and closeout—positioning engineering and architectural consulting as a high-volume, ongoing procurement category for state and local government.
