Hayre McElroy & Associates

What Hayre McElroy & Associates does

Hayre McElroy & Associates (HMA) is a privately held civil engineering and construction services firm headquartered in Redmond, Washington, with additional offices in Kapolei, Hawaii, and Farmers Branch, Texas. Founded in 2006 by principals Gee Hayre (C.B.O.) and Jim McElroy (P.E.), the firm delivers a portfolio of integrated professional services — special inspection and materials testing, construction management, code compliance, geotechnical, civil, and electrical/fiber optic engineering, and environmental design and construction services — to public and private sector clients across the Pacific Northwest, Alaska, and the Hawaiian Islands.

HMA's technical core is an in-house, ISO 17025-aligned full-service materials testing laboratory supplemented by mobile laboratories capable of testing soil, aggregate, hot-mix asphalt, concrete, masonry, shotcrete, fireproofing, and structural steel. Lab accreditations held by International Accreditation Service (IAS), Cement and Concrete Reference Library (CCRL), Washington Association of Building Officials (WABO), and U.S. Army Corps of Engineers (Washington and Hawaii) provide the credentialing base required to compete for federal/military and municipal inspection mandates. Engineering analysis uses industry-standard methodologies including continuous simulation flow modeling (MGS Flood) for stormwater design.

The firm operates a project-based professional services business model, engaging clients directly via on-call and project-specific contracts. Customers span federal/military (U.S. Navy, Fort Lewis Army Base), municipal (Seattle Public Utilities, City of Sammamish), and commercial/retail (COSTCO, Kohl's, hotel and condominium developers). Revenue is generated through fee-based inspection, testing, and engineering engagements with no software, subscription, or productized revenue component, and pricing is quoted per project based on scope and complexity.
