About this IDV
The Department of the Interior's Central Office awarded a $15 million single-award Indefinite Delivery Contract to WBK Engineering LLC, a tribally-owned, SBA 8(a) certified small business headquartered in St. Charles, Illinois, for Demolition Assessment Services. The contract, effective April 18, 2024, through April 17, 2029, was issued under an Indian Small Business Economic Enterprise set-aside designation and supports the agency's Demolition Assessment Services Standard Table of Contents (SATOC) program. The contract modification emphasized compliance with updated federal guidance, elimination of non-statutory sustainability requirements, and enhancement of representational and certification clauses. As the prime contractor, WBK Engineering LLC provides comprehensive demolition assessment and facility evaluation services for tribal education facilities, federal properties, and infrastructure serving Native American communities across multiple geographic locations.
Under this Indefinite Delivery Contract vehicle, four delivery orders totaling approximately $1.29 million have been issued to date, including a $615,284 assessment of Lukachukai Community School in Arizona (completed March 31, 2026) with Historic American Building Surveys and environmental assessments; a $336,331 demolition and disposal site assessment for Quileute Tribal School in Washington (completion April 19, 2026); a $151,537 demolition assessment in Rosebud, South Dakota (completed December 22, 2025); and a $189,870 demolition site assessment for Pearl River Elementary in Mississippi (completed December 22, 2025). All delivery orders were awarded on a firm fixed-price basis without additional set-aside designations, demonstrating the contract's flexibility to support the Department of the Interior's deferred maintenance and infrastructure planning priorities across tribal facilities nationwide.
