Bridge Deck Overlay and Sealing JOC Sets a New Standard

DBA received a new Job Order Contract (JOC) from the Maricopa County Department of Transportation (MCDOT) in late 2017. Earlier this year, we were finally asked to provide services to the County to repair six bridges across the County. Each bridge was contracted as a separate job order and included Epoxy bridge deck sealing services and some minor concrete repairs, as well as restriping and raised pavement markings. Some of the bridge work was completed overnight with full closures approved by MCDOT and others required DBA to have at least one lane open in each direction at all times, requiring completion of those bridges in halves. The six bridges included:
> Eagle Eye Road at the Central Arizona Project (CAP)
> Patton Road at the CAP
> 163rd Avenue at the CAP
> Wickenburg Road at the CAP (also known as Aguila Road)
> El Granada at the Beardsley Canal
> Dysart Road at the Beardsley Canal

The client’s representative, Jimmy Camp – Bridge Engineer commented that “This work really turned out nice. DBA is doing a great job for MCDOT on this project! The overlay work was night work which we required a manufacturer’s representative on site. MCDOT got a better job than anticipated.”

Work at Water Campus Provides Big Infrastructure Upgrades

Utilizing DBA’s Job Order Contract with the City of Scottsdale, several infrastructure improvements projects were recently completed.  The original project to build the Water Campus included funding only for the treatment and conveyance of water.  No funding was spent to improve the general infrastructure for the site which resides in a floodplain.  Several job orders were undertaken over the course of multiple years that included:

• Water Campus Paving Improvements – DBA was responsible for the paving of all dirt access roads throughout the 15-acre site.  Our scope of work included roadway excavation, subgrade preparation, AC and PCC paving, constructing valley gutters, curb and gutter, provide crack sealing, adjust manholes and extensive erosion control.
• Water Campus Drainage and Utility Infrastructure – DBA was contracted to provide earthwork and extensive trenching throughout the facility to install conduit for future solar array uses, install multiple concrete vaults, and manholes.  The drainage improvement project included extensive grading, hand placement of rip-rap on new retention basin slopes, placement of curb, gutter and valley gutters, aprons, adjustments to utilities and AC paving.  The project also included the installation of a 3-barrel, elliptical storm drain pipe going under the perimeter wall and tying into the existing storm drain system under Union Hills Drive.
• The first job order was to provide the Water Campus with improved landscaping and hardscaping that included an awning over the main office entrance, installation of additional decomposed granite on slopes for retention basins, concrete benches and trash receptacles and the relocation of some large cacti to enhance the look of the area near the main office.

DBA Gets National Spotlight

Through DBA’s Job Order Contract with the Arizona Game & Fish Department, we were selected to construct a temporary enclosure for elk at Raymond Ranch in Northern Arizona. The purpose for the enclosure was to provide a location where Game & Fish game wardens could keep the elk after catching them. Ultimately, the elk that were caught were shipped to West Virginia to help reestablish the dwindling elk population on the east coast.

The “wrangling” operation was covered live on national network news including Arizona’s affiliate at FOX (Channel 10).
