About this file
This file comprises the 2025 Standard Specifications for Highway Construction issued by the South Carolina Department of Transportation (SCDOT), which serves as the authoritative technical and procedural framework governing all highway and related construction contracts executed by the agency. The specifications establish comprehensive requirements across multiple construction disciplines, including clearing and grubbing, earthwork, excavation, embankment construction, base and subbase preparation, asphalt pavements, and concrete pavement systems. The document provides detailed definitions, bidding requirements, award procedures, contractor qualifications, material standards, construction methodologies, measurement protocols, and payment terms applicable to state highway projects. Key administrative sections address prequalification of bidders, proposal guaranties, bond requirements, contractor liability insurance, contract execution, scope of work modifications, change order procedures, dispute resolution through Dispute Review Boards, and inspection and acceptance protocols. The specifications incorporate performance standards for equipment, weather restrictions, compaction requirements, surface smoothness tolerances, and rideability specifications to ensure consistency and quality across all SCDOT construction projects.
The specifications establish binding technical and commercial standards that contractors must follow to achieve contract compliance, with detailed measurement and payment methodologies for each line item and work category. Material sourcing requirements include provisions addressing recycled asphalt pavement, recycled asphalt shingles, iron and steel products, and environmental compliance obligations under federal and state law. The document addresses contract administration mechanisms including the role of the Resident Construction Engineer, change order procedures for differing site conditions and value engineering opportunities, extra work authorization processes, and formal claims procedures for contractors seeking adjustments to contract time or compensation. Pricing mechanisms include force account work provisions for extra items, compensation for quantity overruns and underruns, mobilization payments, and material-on-hand provisions, with final payment contingent upon full project acceptance and completion of all required documentation.
