THA has established an excellent reputation within its service areas.

The firm’s broad regional experience continues to contribute to its extensive knowledge and information base, making THA an invaluable engineering and surveying resource.

COMPANY HISTORY AND PHILOSOPHY

THA originated in California’s Eastern Sierra, created by the merger of Triad Engineering and Holmes Engineering and Development Company in 1994. Triad Engineering was originally established in Mammoth Lakes in 1979 and Holmes Engineering and Development Company in Bishop in 1963. The two full-service civil engineering and surveying companies served a broad client base in Inyo and Mono Counties. This broad geographic region provided THA with very diverse project knowledge that significantly enhanced its capacity to develop the best engineering solutions for its Clients. Since 1994, THA has added five offices serving an area extending from the Sierras west to the Pacific Coast and from Napa Valley south to Santa Barbara.

The company principals and managers realize that the success of THA is directly related to the success of its Clients and employees. THA pays personal attention to each Client and works hard to build lasting client relationships. The firm prides itself in the high percentage of repeat customers and an environment that fosters the professional growth and personal development of its employees.

THA understands that time and money are always significant Client priorities along with high quality and creativity. To meet these client needs, a company Principal or Branch Manager is assigned to each project to provide quality assurance and consistent service throughout the length of the contract. In addition, because of its ability to pool company assets, any THA office has access to added resources as required to meet challenging deadlines on projects of all sizes. The firm has the proven ability to develop and maintain project specific schedules and keep work within budget. THA’s goal is twofold - to deliver cost effective quality products and services on time and within budget and to create a satisfied Client.
