Quality assurance for the construction of the twin chimneys landfill unit 4 cell 4

Greenville County is soliciting sealed electronic proposals for Quality Assurance (CQA) services for the construction of the Twin Chimneys Landfill Unit 4 Cell 4, a 10.3-acre municipal solid waste landfill project. The selected firm will provide comprehensive Construction Quality Assurance field services in compliance with the Construction Quality Assurance Plan included in the project manual prepared by HDR Engineering, Inc. dated April 2024. Proposers must demonstrate experience with at least five similar CQA projects in the last 5 years and submit a detailed proposal covering company background, qualifications, references, and project approach. The evaluation will be based on six weighted criteria scored 0-5 points, including quality assurance experience, organization and staffing, project approach, responsiveness, cost, and references. Key project dates include a non-mandatory pre-proposal meeting on May 29, 2024, a question submission deadline of June 10, 2024, and a proposal submission deadline of July 16, 2024 at 3:00 pm. The anticipated contract award is July 31, 2024, with contract negotiations from July 31 to August 23, 2024, and a planned Notice to Proceed on August 23, 2024. The successful contractor will be required to provide a detailed report of quality assurance services to the South Carolina Department of Health and Environmental Control (SCDHEC) within 30 days of substantial project completion.

The procurement does not specify any specific set-aside designations or restrictions for disadvantaged enterprises. Insurance requirements include comprehensive general liability ($1,000,000 per occurrence), automobile liability ($1,000,000 per occurrence), and statutory worker's compensation. While the exact contract value is not explicitly stated, the project involves a complex landfill liner system construction that will require detailed technical oversight, including installation of a 24-inch initial soil barrier, geosynthetic clay liner, HDPE geomembrane, and geocomposite drainage media. The project documents suggest a comprehensive and technically demanding scope of work that would likely require specialized environmental engineering and quality assurance expertise. A sample services agreement is included in the procurement documents, which indicates the potential for up to four one-year contract renewals. The procurement is structured to ensure rigorous quality control and environmental compliance for the landfill cell construction, with a focus on precise engineering specifications and thorough documentation of the construction process.
