UNSPSC 81103406: Conceptual Studies and Pre-Front-end engineering design services

The FEED stage comes after the pre-FEED stage and before the Detailed Design stage in complex engineering Studies, Concept design & Engineering, Pre-Front End Engineering Design Services.

UNSPSC 81103406 Conceptual Studies and Pre-Front-end Engineering Design Services (Commodity) encompasses preliminary engineering, feasibility analyses, environmental documentation, design support, and construction-phase oversight that state and local governments procure for infrastructure planning and capital project advancement. Recent state and local opportunities show solicitations for coastal resiliency engineering, water and wastewater system design, stormwater drainage assessment, roadway improvements, and project management support—work that moves projects from concept through design readiness or early construction phases. Issuing bodies include county governments (Sarasota County, Chatham County, Escambia County, Collier County, Harris County Toll Road Authority), cities (Savannah, Fort Myers, Phoenix, Pembroke Pines, Statesboro, Dahlonega, Tolleson, Hernando, Rockmart, Hiawassee, Gainesville, McDonough), water districts (West Basin Municipal Water District, Great Lakes Water Authority, Eastern Municipal Water District), state departments (Georgia Department of Transportation, Texas Facilities Commission, Oregon Department of Transportation), and regional authorities (Great Lakes Water Authority). GDOT appears as a repeat buyer with multiple concurrent solicitations for design, engineering consulting, government estimating, construction management, and project-specific engineering services across transportation corridors and bridge replacements.

Recent representative opportunities span multiple geographies and service lines. Sarasota County posted a Request for Professional Services on July 16, 2026 for coastal engineering services supporting the Casey Key Resiliency Project—permitting coordination, regulatory approvals, and design of beach restoration and 45 coastal structures—with proposals due August 19, 2026. The Great Lakes Water Authority (Wayne County, Michigan) issued an RFP on July 13, 2026 for engineering project management and inspection staff augmentation, seeking five full-time equivalent project managers and two to four construction inspectors, with proposals due August 10, 2026. West Basin Municipal Water District posted an RFP on July 13, 2026 for on-call professional engineering services spanning hydraulic modeling, facility design, water quality studies, and construction support, with up to five firms to be awarded through June 30, 2029 and a total estimated value of $3 million. Chatham County and partnering jurisdictions (Georgia) issued multiple quality-based selection SOQs in July 2026 for roadway design projects—President Street Grade Separation, Old River Road Widening, and SR 204 Safety & Operational Improvements—all due August 14, 2026, with two-phase selection processes emphasizing qualifications and technical approach. Activity concentrates in Georgia, Florida, Michigan, Texas, Arizona, and the Pacific Northwest, with particularly dense recent posting activity in Georgia counties and Florida water utilities pursuing grant-funded and capital improvement work.
