Job Order Contracting (JOC) Services - Stormwater Drainage

Dorchester County, South Carolina is seeking qualified firms to provide Job Order Contracting (JOC) Services for General Stormwater Construction Projects through a competitive Request for Proposals (RFP). The procurement seeks multiple contractors to perform repair, rehabilitation, replacement, and minor new construction work for stormwater drainage infrastructure throughout the county. Proposing firms must demonstrate the ability to self-perform at least 51% of work and submit adjustment factors for pre-priced construction tasks in a Task Catalog, with separate factors for different work environments and hours. Evaluation criteria will include Firm Qualifications and Safety & Experience (30%), Cost Proposal (30%), Capacity & Availability (20%), and References & Past Project Performance (20%). Key dates include a non-mandatory pre-proposal virtual webinar on December 18, 2025, at 10:00 AM, a deadline for written questions on January 7, 2026, at 11:59 PM, and proposal submissions due January 15, 2026, at 2:00 PM through the OpenGov Procurement Portal or by mail/hand delivery. Contractors must provide proof of Experience Modification Rates for workers' compensation and meet specific insurance requirements, including $1,000,000 in General Liability and Automobile Liability coverage.

The solicitation does not specify explicit set-aside designations or restrictions for disadvantaged enterprises. Contractors must obtain all necessary permits and licenses required by South Carolina, municipalities, or the county, and will be responsible for comprehensive project execution. The contract base term is one year with four optional one-year renewal terms, potentially spanning a total of five years. Dorchester County intends to award multiple JOC contracts and will exclusively use these new contracts, meaning firms with existing expired contracts must respond to this RFP. Payment terms include 30-day invoice processing with 90% of completed work eligible for payment and 10% held as retainage until final completion. While specific budget ranges are not explicitly stated, the county will pay job orders as lump-sum fixed prices upon completion of detailed scopes of work. The solicitation includes a 6.00% administrative fee payable to The Gordian Group, which must be incorporated into the adjustment factors, and performance and payment bonds equal to 100% of the Job Order Price may be required when requested.
