Catch Basin Retrofit - Union County

The South Carolina Department of Transportation (SCDOT), specifically the Union Maintenance office, is soliciting contractor services for a catch basin retrofit project located in Union County. The procurement involves retrofitting one existing Type 7 catch basin to a Type 18 catch basin on Union Boulevard (S-44-124), situated between Horseshoes Circle and Brookside Drive. The project requires contractors to provide comprehensive services including labor, materials, debris removal, and traffic control, with a primary objective of repairing the separation at the connection of the cross line box and stubbed reinforced concrete pipe under the existing catch basin. Work must strictly adhere to standard drawing 719-018-01, which provides detailed construction specifications for catch basin installations, including dimensional requirements, material options, and configuration details. The project demands contractors demonstrate expertise in infrastructure modification, with specific technical capabilities including ability to work with precast concrete components, comply with AASHTO M235 standards, and ensure ADA and traffic compatibility. The Notice to Vendors was originally issued in March, with the current posting dated November 18, 2025, though a precise proposal submission deadline is not explicitly stated in the available documentation.

While no specific set-aside designations or enterprise restrictions are explicitly outlined in the provided documents, the project appears open to qualified contractors with appropriate infrastructure retrofit capabilities. The procurement does not indicate any incumbent vendors or mandate specific technological integrations beyond the standard SCDOT catch basin design specifications. The documentation does not provide a specific budget range or award value for the project, suggesting potential flexibility in pricing and scope. Interested contractors will need to demonstrate technical proficiency in civil infrastructure modification, specifically catch basin retrofitting, and comply with SCDOT's rigorous technical standards. Emmett Kirwan is identified as the Procurement Officer/Manager and serves as the primary point of contact for potential vendors seeking additional information about the project. Contractors who previously submitted pricing for the initial informal quote request in March are not required to resubmit unless unable to honor their original pricing.
