The Phoenix Office, located in Tempe, Ariz., opened for business in January 1995. Today, the Phoenix team includes more than 55 professional, technical, and administrative staff. Clients include a mix of both public and private sector clients, as well as national clients. Being in one of the fastest growing areas of the country, they do a particularly large volume of work associated with transportation projects, energy development and power transmission, and commercial and retail development. Services include the design of reinforced earth structures, including mechanically stabilized earth retaining walls, reinforced earth slopes and soil nail retaining walls, which is somewhat unique within Terracon. The longest on-going project to date is our pavement management services for the Maricopa County Community College District (the largest community college district in the United States). We manage more than 9 million square feet of pavement(s) for the College District, located on 19 campuses throughout Maricopa County.

Western Area Power Administration (Western) reconstructed the 69-kV Davis Dam to Kingman TAP transmission line. The new line, constructed with a combination of steel and concrete structures, will replace an existing wood supported line that was constructed in 1947. The new transmission line is approximately 27.3 miles in length and extends from the substation at Davis Dam located on the Colorado River on the west end, through Golden Valley, and terminates at the Mohave Electric Corporation's Kingman, Arizona TAP.

The lateral and vertical extent of hexavalent chromium, used in the plating process, produced the contamination in the soil which was defined by Terracon's environmental group. Terracon then developed a remedial action plan.

Terracon's Phoenix office has been involved in both the geotechnical and construction materials and engineering testing services for the Arizona Diamondbacks/Colorado Rockies Spring Training Facility. Terracon's services on the $120+ million facility were provided as part of an SRPMIC on-call contract awarded in 2009. Terracon was an active participant in the design meetings, which allowed us the opportunity to provide extensive construction-related input during the design stage that resulted in the creation of a unique foundation system. Prior to final design of the project, Terracon…
