Front-End and Specifications - Phase 1 - W912DQ26RA065 - 20260925.pdf

This file contains the front-end and specifications documentation for Phase 1 of a design-build construction project for levee access manholes at the Fairfax-Jersey Creek Levee Unit in Kansas City, Kansas. The U.S. Army Corps of Engineers, Kansas City District is procuring design and construction services to install access manholes that will facilitate access to an existing seepage collection system within the levee along the Missouri River. The project is classified under NAICS Code 237990 with a $45 million size standard, and the contract award amount shall not exceed $3,400,000.00 for all contract line items. The estimated project value ranges between $1,000,000.00 and $5,000,000.00.

A critical requirement of this solicitation is that invasive mass excavation methods such as trenching are strictly prohibited, and contractors must employ minimally invasive excavation methods to complete the work. This specification significantly constrains the construction approach and requires specialized techniques and equipment to access and install the required infrastructure while preserving the integrity of the existing levee structure. The Solicitation Number is W912DQ26RA065, and this front-end specifications document establishes the technical and contractual framework for Phase 1 of the project.
