Design and Construction of Levee Access Manholes for Fairfax-Jersey Creek Levee Unit (Kansas City, Kansas)

Solicitation # W912DQ26RA065

The U.S. Army Corps of Engineers, Kansas City District, is soliciting design-build construction services for the installation of access manholes at the Fairfax-Jersey Creek Levee Unit in Kansas City, Kansas. The project aims to facilitate the inspection of approximately 27,000 feet of existing perforated corrugated metal seepage collector pipe, with manhole depths estimated between 10 and 25 feet. To maintain levee integrity, the government strictly prohibits invasive mass excavation methods such as trenching, requiring the use of minimally invasive excavation techniques. Key deliverables include a Drilling and Invasive Program Plan approved by a licensed professional engineer or geologist, temporary flood protection plans, as-built drawings, and verification that collector lines can be video inspected from each manhole. This is a firm-fixed-price contract with an estimated magnitude between $1,000,000 and $5,000,000, though the total award amount shall not exceed $3,400,000. The procurement is conducted in two phases, with Phase 1 focusing on qualifications and technical approach rather than pricing. Evaluation factors for award include design concepts, performance confidence, technical approach and qualifications, and small business participation, with design concepts being the most important non-price factor. The project falls under NAICS code 237990 with a size standard of $45 million and is subject to the Davis-Bacon Act and Buy American Act requirements. Offerors must submit proposals via the PIEE Solicitation Portal using mandatory templates for vendor information, experience, and technical qualifications.
