Excavation of Soils at APEX Site

The City of Wichita's Public Works & Utilities/Environmental Health Division is seeking bids for a soil excavation project at the APEX East Source Area located at 1234 N. Wellington in Wichita, Kansas. The procurement is a Request for Bid (RFB) that requires excavation and removal of approximately 200 cubic yards of concrete rubble and 1,420 cubic yards of contaminated clay soils, with direct transportation and disposal to the Plumb Thicket Landfill in Harper County. Contractor qualifications include a minimum of two years of experience in similar environmental remediation services, compliance with all applicable laws, and provision of appropriate permits and insurance. Key project deliverables involve excavating contaminated soils related to chlorinated solvent contamination (primarily trichloroethylene), backfilling with clean commercial fill sand, and capping with six inches of asphalt. The solicitation timeline includes a pre-bid meeting on October 6, 2025, at 10:00 a.m., qualifications submittals due by October 17, 2025, and final bids due by October 31, 2025, at 10:00 a.m. Award will be based on the lowest and best total base bid, with the City reserving the right to accept or reject any bid. The anticipated project duration is 50 days from the Notice to Proceed, with potential City Council approval on November 11, 2025, and purchase order release on December 12, 2025.

The procurement requires a 5% bid security and performance/payment bonds, but does not specify any specific set-aside designations or restrictions for disadvantaged enterprises. While no incumbent vendors are mentioned, the project is part of the broader North Industrial Corridor (NIC) site-wide groundwater remediation efforts. The solicitation does not explicitly state a total project budget or precise award value, though tipping fees for the Plumb Thicket Landfill will be billed directly to the City. The project appears to be a targeted environmental remediation effort focused on addressing historical industrial contamination in the Wichita area. Prospective bidders will need to demonstrate technical capability, environmental compliance expertise, and the ability to efficiently execute a complex soil excavation and disposal project within the specified timeframe. The procurement is specific to Sedgwick County and involves direct coordination with the City of Wichita's Public Works Department.
