UNSPSC 81103405: Onshore engineering procurement and construction services

Onshore Engineering Procurement and Construction a single point of responsibility, the Contractor is responsible for all design, engineering, procurement, construction, commissioning and testing activities etc.

UNSPSC 81103405 Onshore engineering procurement and construction services, a Commodity code, encompasses the design, planning, feasibility analysis, and construction administration services state and local governments procure for water and wastewater infrastructure, stormwater and flood mitigation systems, roadway and transportation improvements, facility assessments and renovations, and environmental remediation and permitting work. Recent solicitations show municipalities and counties issuing RFPs and RFQs for comprehensive master plans (20-year hydraulic modeling and capacity assessments for water systems), shoreline adaptation and vulnerability planning aligned with federal grant programs, design-build and design-bid-build roadway projects including turn lanes and traffic signals, construction engineering and inspection services across multiple concurrent projects, and specialized engineering studies in geotechnical analysis, environmental compliance, and utility coordination. The issuing-body mix spans city public works and transportation departments, county commissioners and capital programs offices, regional water authorities, hospital districts, university facilities departments, and special-purpose water and wastewater authorities. Repeat buyers include the City of Phoenix (multiple wastewater treatment plant and street transportation projects), the City of Fort Myers (stormwater drainage, waterway restoration, and MEP services), and county governments managing countywide transportation and infrastructure portfolios on task-order or on-call bases.

Recent activity concentrates in Florida (Fort Myers, Tampa Bay region, Broward County, Collier County, Palm Beach County, Okaloosa County, Orange County), Arizona (Phoenix), Texas (Dallas, San Antonio, Lewisville, Walker County), and emerging pockets in New Jersey, Connecticut, and California. Representative recent opportunities include the City of Edinburg (Texas) requesting water and sewer system master planning with 20-year hydraulic modeling and capital improvement prioritization (RFQ20271, due October 6, 2026); Santa Clara County (California) soliciting a shoreline adaptation plan team for sea level rise risk assessment across six participating cities (RFPCEOFY260615, due November 6, 2026); the Town of Manchester (Connecticut) requesting design engineering for a 2,000-linear-foot box culvert replacement in a downtown urban environment with 12–14 month design schedule (RFP252683, due November 10, 2026); the City of Phoenix requesting qualifications for construction administration and inspection services on a $7.9 million wastewater lift station and force main project (WS90501000CAI, due October 30, 2026); and Hillsborough County (Florida) seeking construction engineering and inspection services under a $6 million geotechnical and materials testing contract structure (RPS2600367, due November 3, 2026). Most opportunities are issued under RFP or RFQ (qualifications-based selection under state consultants competitive negotiation acts), with task-order or on-call frameworks common for continuing-services contracts capped at $500,000 to $2.5 million per assignment. Set-asides and preferences appear in Florida solicitations (SBE, MBE, local-vendor preference points) and federal-funded work (Davis-Bacon wage, FTA Buy America, FEMA compliance requirements).
