North Walton Sports Complex – Geotechnical Investigation Services

The Walton County Board of County Commissioners is soliciting proposals from qualified geotechnical engineering firms to provide subsurface investigations, laboratory testing, and engineering analysis for the proposed North Walton Sports Complex in DeFuniak Springs, Florida. Located at Parcel ID 25-3N-19-19070-001-9040, the project site will eventually host athletic fields, high-mast lighting, amenity buildings, and supporting infrastructure. The scope of work requires the execution of eight structural soil borings to a minimum depth of 30 feet below ground surface using hollow-stem auger or rotary wash methods. The investigation must include continuous Standard Penetration Testing per ASTM D1586 and laboratory testing to verify soil classifications according to AASHTO and Unified Soil Classification System standards. The primary deliverable is a comprehensive Geotechnical Engineering Report signed and sealed by a Professional Engineer licensed in the State of Florida. This report must provide critical data for structural foundation design, including bearing capacities, settlement estimates, lateral soil parameters for lighting poles, and estimated Seasonal High Water Table elevations. All exploration programs must comply with the Florida Department of Transportation Soils and Foundation Handbook. Interested firms must submit their responses via the OpenGov portal by November 16, 2026, ensuring that technical proposals and cost proposals are submitted as separate components. Evaluation will be based on cost, lead time, quote validity, and the provision of two professional references for similar scopes of work.
