Walter N. Coffman Inc.

Walter N. Coffman Inc., a self-certified small disadvantaged business based in San Diego, California, operates exclusively as a subcontractor in federal construction work, with all six recorded awards routed through Harper Construction Company, Inc. as prime.

The vendor's entire award footprint consists of subcontract modifications to a single prime contract at Yuma Proving Ground, Arizona, executed by Harper Construction in February 2022. Work performed includes fire alarm and life safety panel installation in electrical rooms, power and data connections to government-furnished equipment, and schedule extensions for a Special Operations Forces hangar project. Combined obligated dollars across all six sub-awards total $707 thousand, with the substantive work — fire alarm panel installation and FFE connections — valued at approximately $62 thousand in net price increases; the remaining modifications reflect no-cost time extensions. The customer is exclusively the Department of the Army Corps of Engineers Engineering District Los Angeles, accounting for 100% of recorded awards.

The vendor's federal engagement is narrowly scoped: all work falls under Commercial and Institutional Building Construction (NAICS 236220) and is concentrated in a single construction program at a single Army facility. No prime contracts, IDIQs, BPAs, or government-wide vehicles appear in the source data. Activity is four years old; the most recent award date is February 23, 2022. No recompete exposure or pipeline activity is evident from the source. The vendor does not appear in the source as holding seats on any parent contract vehicles, and no teaming relationships beyond the Harper Construction prime are documented. The SDB designation is self-certified; no 8(a), HUBZone, SDVOSB, WOSB, or other SBA program certifications are noted in the source.
