Gastinger And Walker Architects, Inc.

Gastinger And Walker Architects, Inc., doing business as Gastingercalker&, is a Kansas City-based for-profit architecture and construction management firm operating exclusively as a prime contractor on federal construction and facility projects, with no set-aside designations across its portfolio. The vendor holds 258 prime awards spanning 1986 to present, generating $559.7 million in combined potential value across seventeen federal customer agencies, though only $30.2 million (5% of potential value) has been obligated to date, reflecting the vendor's position on long-duration indefinite-delivery vehicles and blanket purchase agreements rather than completed, invoiced work.

Gastinger And Walker's capability footprint centers on construction management, design review, cost estimating, scheduling, contract administration, and facility inspection services for federal buildings and infrastructure projects. Representative recent work includes a $5.15 million task order from the National Nuclear Security Administration for construction management services at the NNSA Kansas City Campus (awarded October 2023, extending through October 2028 under the GSA Multiple Award Schedule), a $262,595 BPA call from GSA Public Buildings Service Region 6 for the Bolling Upper Roof Replacement Project in Kansas City (awarded August 2023), a $192,215 BPA call for water-leak remediation at the Neal Smith Federal Building in Des Moines (awarded January 2024), and a $83,003 BPA call for roof fall protection upgrades at the Denney Project in Lincoln, Nebraska (awarded September 2026).

Customer concentration is heavily weighted toward GSA Public Buildings Service, which represents 80% of recent award count. GSA Public Buildings Service Region 6 alone accounts for 87 awards and $44.4 million in potential value; however, the largest single customer by dollar value is GSA Public Buildings Service Region 3, which issued a $500 million multiple-award blanket purchase agreement for construction management and related services (awarded November 2023, extending through December 2028). Other active customers include the Department of Energy's National Nuclear Security Administration, the Department of Veterans Affairs, and the Department of the Army, accounting for the remaining activity.

The vendor's vehicle portfolio is anchored to GSA contracting mechanisms: the Multiple Award Schedule (68 task orders, $538.1 million combined potential value) dominates the portfolio, followed by several indefinite-delivery contracts and the Professional Services Schedule. Recent activity is sparse — one award in 2024, one in 2025, one in 2026 — but this reflects the vendor's transition from direct task orders to seats on high-value blanket purchase agreements issued by GSA Region 3 rather than declining demand. Only one award (valued at $83 thousand) reaches completion within the next twenty-four months, indicating minimal recompete exposure in the near term.

SCI-reported invoicing across five service-contract records totals $3.8 million over FY2022–FY2025, with FY2022 showing an anomalous FTE count (441 FTEs) that suggests a single large labor-intensive contract not representative of ongoing operations; subsequent years show stable invoicing around $900 thousand annually across three to four FTEs. Median government-paid hourly rates on prime SCI records run $108.05 per hour, with senior labor pricing through $111.86 per hour and entry-level work at $33.10 per hour. The vendor maintains zero subcontractor engagement across its prime SCI records, indicating internal delivery of construction management and inspection services rather than reliance on subcontractor support.
