The City of Columbia, South Carolina, is seeking bids for the SD8539 Manse Street Channel Rehabilitation Project through Solicitation Number BID034-25-26-JAH Addendum 3, with a response deadline of May 26, 2026. This is a municipal construction solicitation governed by custom-drafted terms rather than standardized Federal Acquisition Regulation clauses, and all questions must be submitted through the city’s e-Procurement platform, IONWAVE. The project involves the installation of sanitary sewer systems, roadway improvements, subsurface drainage, ADA-compliant sidewalks, manholes, pipes, drainage structures, and Diamond Pro Concrete Facing Units, all in accordance with the SD8539 Manse Street Specifications and referenced standards including ASTM, AASHTO, and SCDOT highway specifications. The work is to be performed entirely within South Carolina, with inspection and acceptance occurring at the project site upon delivery. The City intends to award the contract using the Lowest Price Technically Acceptable methodology, selecting the lowest responsive and responsible bidder whose proposal meets all material requirements. All bidders must submit their proposals electronically via the IONWAVE portal and include mandatory documents such as the completed Bid Form, Financial Statements for the last three audit periods, a Business Information Record for subcontractors, proof of compliance with South Carolina’s 15% Columbia Disadvantaged Business Enterprise participation goal, and certifications for Unique Entity ID and CAGE code.

Additional requirements include 48-hour notice for inspections, soil testing by approved laboratories, withholding of 2% of payments to non-resident contractors, and adherence to OSHA and AGC safety standards.

No pricing data is pre-filled; bidders must fill in all unit and extended prices for line items including excavation, backfill, riprap, concrete, rebar, and structural steel. Final payment is contingent upon submission and approval of storm sewer records, and all materials must be delivered in undamaged packaging with proper labeling, material certificates, and inspection documentation.
