Work Continues at Palo Verde Nuclear Generating Station

12 Sep 2016/in , , , /by

For funding reasons at Arizona Public Service (APS), the original $1.3 million Make-Up / Blowdown Hypochlorite Trench Structures project was broken into two phases.  The first phase, “Trench #20” started in late 2015 and the second phase, “Trench #2″ started in early 2016.  The scope of work included digging two large trenches (315 LF and 140 LF, respectively) that were then compacted.  Each trench required outfitting of rebar-reinforced, precast, concrete vaults running the entire distance to house pipes carrying sulfuric acid and water to the main cooling towers.  Pipe sizes ranged from 1/2″ to 4” in diameter.  Once piping was installed, the entire system was checked for leaks and inspected.  The final phase of the project included the forming of cast-in-place concrete lids for the entire system that included steel grating for maintenance access.

Shea Homes Hires DBA for Structures

18 Jul 2016/in , , /by

DBA was recently contracted by Shea Homes to construct two, three-barrel, cast-in-place concrete box culverts (10 x 4) along North Verde River Way East in the planned Tegavah development in North Scottsdale. Construction of the project included:
* Earthwork
* Structure formwork
* Cast-in-place concrete pouring and finishing
After the culverts were complete, the owner discovered that the parapet walls on the bridges were too low for safety. The designer was contacted and DBA’s crews were contracted to dowel into the existing parapet wall to add another 1.5 feet of concrete to the top of the walls.
Tegavah (formerly Vista Verde Golf Community) sits on 850 acres in North Scottsdale and when complete will offer 1,250 home sites, golf course, fitness center, multi-purpose areas, outdoor pool with hot tub, pickleball, tennis courts and other amenities including hiking and biking.
