Underground Utility Construction and Water-Wastewater Improvements

Project Owner: City of Tempe
Project Type: Job Order Contracting
Construction Dates: 10/15 to 10/20

This wet infrastructure JOC includes water, sewer, reclaimed water, storm drain, and pipeline construction. Total quantities to date include: 9,273 LF of pipe, 110 valves, and 5,974 SY of pavement.

Achen-Gardner completed five JOs (Job Orders) which comprised one waterline replacement project that was located on College Avenue from Southern Avenue to Alameda Drive and it included repair of 20 long-side services, completion of nine mainline tie-ins, and the restoration of hardscape that was impacted due to construction activity.

We completed a JO that included the installation of 2,586 LF of 8” sanitary sewer pipe and 11 precast manholes, 2,385 SY of asphalt replacement, and 9,345 SY of slurry seal, all within limited roadway space in Carver Ranch Estates, an affluent gated community.

Our crews completed one JO that included the rehabilitation of 4 LF of 8" sanitary sewer pipe utilizing UV CIPP at the intersection of College Avenue and 7th Street in downtown Tempe. 

Achen-Gardner completed three emergency JOs which resulted in the repair of a 60” sanitary sewer manhole, 30” water main break in middle of the Rural Road and Alameda Drive intersection, and a ruptured 4” water line lateral near the Rural Road and Broadway Road intersection. In each instance Achen-Gardner received the emergency call from the City, mobilized our response team to the location within one hour, identified the scope of the emergency, and developed a plan to quickly stabilize the situation. After securing the site, we worked closely with the City in evaluating options to ensure the final repair provided the best value.

We completed a waterline replacement on 5th Street from Farmer Avenue to College Avenue. Work included approximately 3,751 LF of pipe (3,286 LF of 12", 252 LF of 8", 213 LF of 6") and associated appurtenances with a point of connection to the City of Tempe water system. The downtown location and high level of vehicle and pedestrian traffic required a diligent approach to construction sequencing and safety. We maintained continual traffic flow, access to local businesses and City of Tempe facilities (City Hall and Municipal Building, Transportation Center, Police/Courts Building, etc.), and a clean and safe work area. 

We are currently working on a JO that includes the replacement of water valves throughout the City and another JO that includes an emergency water line replacement.
