The Grand Strand Water and Sewer Authority (GSWSA) is seeking proposals for Construction Manager at Risk (CMAR) services for Phase 1 PFAS upgrades at the Myrtle Beach Water Treatment Plant. The project involves adding powdered activated carbon (PAC) for PFAS removal, requiring new PAC silos, a feed building, slurry pumps, and a dewatering centrifuge. GSWSA intends to award a preconstruction services contract, followed by a construction services contract if mutual agreement on a Guaranteed Maximum Price (GMP) is reached. Attendance at a mandatory preproposal conference call on May 26, 2026, is required for eligibility. Voluntary site visits are permitted between May 15 and June 19, 2026. Requests for information must be submitted by June 10, 2026. Proposals are due electronically by June 19, 2026, at 5:00 p. m. EST, with hard copies to follow. The project is subject to South Carolina State Revolving Fund (SRF) program requirements, including Disadvantaged Business Enterprise (DBE) participation, Build America/Buy America provisions, and Davis-Bacon Act labor standards. Proposers must demonstrate qualifications, including experience with water/wastewater treatment plants and collaborative delivery methods. The contract will be awarded based on evaluation criteria including project performance, personnel qualifications, safety, project understanding, approach, and fees. The estimated value of the owner's opinion of probable construction cost is $15,618,000.
The proposal submission deadline is June 19, 2026, at 5:00 p. m. local time EST.
The document outlines progress payments based on applications submitted by the construction manager and certified by the architect. Payments are generally due within twenty-one days of receipt of the approved application for payment.
The contractor warrants that materials and equipment will be of good quality and new, and the work will conform to contract documents and be free from defects. Warranties generally commence on the date of substantial completion and last for one year, unless otherwise specified.
Proposals will be evaluated based on criteria including project performance, personnel qualifications and experience, safety performance, project understanding and approach, and preconstruction and construction services fees. The award will be made to the responsive and responsible proposer determined to be most advantageous to GSWSA.
Proposers must meet mandatory responsiveness requirements, including attending the preproposal conference call, timely submission, inclusion of a signed cover letter and affidavit, and responsiveness to the RFP. Specific qualifications include debarment status, valid South Carolina contractor's license with a water/sewer plants classification (WP5), ability to obtain performance and payment bonds, and recognition of project funding requirements.
The contract documents mention liquidated damages for failure to achieve substantial completion by the agreed-upon date, with a daily rate to be determined. Failure to comply with contract provisions may also lead to rejection of submittals, termination for cause, or other remedies.
Voluntary site visits of the Myrtle Beach Surface Water Treatment Plant may be accommodated between May 15th and June 19th, with the exception of May 25th, upon request. A minimum notice of 48 hours is required.
