DBA Responds to Emergency Repairs in Chandler

25 Sep 2019/in , , /by

DBA crews recently responded to an emergency request for the construction of four catch basins on the west side of Arizona Avenue at Chicago Street, as well as new construction of ADA ramps, sidewalk, curb & gutter, the placement of PCC paving, and tie-ins to existing piping on the east side of Arizona Avenue directly adjacent to City Hall.

Both projects were completed by DBA who responded quickly to a special request that allowed the remaining portion of the infrastructure contract for the new parking garage to continue without delay or further disruption. Extensive underground utilities had been discovered and disturbed prior to DBA’s arrival on scene. This added to the project’s complexity and required fast thinking in the field to quickly resolve the issues and reestablish utility connectivity. The special request came from another prime contractor who had released his civil subcontractor from the project due to performance issues.

Access Road Gets Safety Improvements

20 Sep 2019/in , , /by

DBA recently completed another access roadway improvement project for Salt River Project at Horse Mesa Dam.  Along the steep, winding narrow access road from Apache Trail down to the dam, there are a total of 6 switchback areas that had become unsafe for driving (particularly in the early morning hours).  DBA was contracted by the utility company to improve one of the worst corners by building a retaining/curb wall, an anchored and rebar reinforced turndown, and improved driving surfaces that were rebar reinforced and tined for better traction.  The project also called for the installation of additional CMP under the roadway and the construction of two modified concrete headwalls for improved drainage.

Adding to the complex project in an extremely remote area of Maricopa County, was the delivery of concrete to the site. Due in part to the steepness of the access road and the tight turns, concrete mixer trucks could only haul 6 CY per load. The entire project required a total of 160 CY. As A result, the project was completed in four weeks.

Wellton-Mohawk Bridges Moving Ahead

04 Sep 2019/in , , , /by

DBA submitted a bid to ADOT for the demolition and reconstruction of two bridges in Yuma County over the Mohawk Canal. Located off the ADOT highway system on Avenue 37E and Yuma County’s 6th Street is one bridge. The other bridge is located on Avenue 46E and Yuma County’s 1-1/2 Street. Both bridges require the removal and replacement of the bridge girders, removal and replacement of the bridge railing/barriers, construction of new bridge abutments, removal and replacement of the asphaltic concrete pavements on the deck and additional 50-foot approach slabs will be constructed.

DBA crews started on the project in late August and expect to be complete by the end of 2019. The bridge construction is directly over an irrigation canal that is used for the agricultural community in Wellton. As a result, extensive measures have been taken to protect the water from construction debris and chemical intrusion.

Tempe Pedestrian Bridges Move into Second Phase

Earlier in the year, DBA was awarded a contract to complete the rehabilitation of two pedestrian/bicycle bridges in Tempe that cross US-60 (Superstition Freeway). Both bridges are located between the I-10 and Loop 101 interchanges (Country Club Drive and College Avenue) and required:

Painting the bridges

Installation of new LED light fixtures

Remove/replace or repair concrete paving

Installation of concrete sleeper slabs

Remove/replace or repair portions of the concrete retaining walls

Seal cracks along the concrete paving

Repair the pedestrian handrails

The bridges were built in 2003 and 2004, respectively, are frequently used by the residents in the neighborhoods, and required extensive reparations for safety concerns and aesthetics.

DBA Constructs Two New Shooting Ranges

09 Jul 2019/in , , , /by

Under our existing Job Order Contract with the Arizona Game & Fish Department, DBA has completed a new shooting range in Kingman and is under construction for a new sharp-shooter range in Sierra Vista.

Near Kingman, at the 7-Mile Shooting Range Facility, DBA was responsible for the earthwork associated with the reconstruction of a high-power rifle range with 50 meter long berms on both sides of range with 7-foot high retaining walls.

Within the same facility, DBA was contracted to dig out a new below-grade hand-gun shooting range with 20-foot high retaining walls.

Upon completion of the Kingman project, DBA was awarded a second contract with AZ Game & Fish to build a new sharp-shooter facility in Sierra Vista, Arizona. The project will be built in three phases to include the West Berm Range 3 with 20-foot tall earthen walls, the backstop berm at Range 3, and a 20-foot tall backstop berm at Ranges 1 & 2.

Both facilities required heavy earthmoving operations. The Sierra Vista facility required hauling and placement of more than 19,230 CY.

DBA Part of Surprise’s New Veterans Reflection Circle

01 Jul 2019/in , , /by

Volunteerism is an important part of being an employee of DBA Construction. At a recent City of Surprise Council Meeting, DBA project management stepped up to assist the City along with several other contractors, consultants, and material suppliers to donate labor and materials to build a new memorial for wounded combat veteran and long-time Surprise resident, Brian Mancini.

The project, Veterans Reflection Circle, is going to be built between the main library and City Hall near the lake and will include a plaque commemorating Brian’s service to his country as well as a water feature, landscaping and hardscaping provided by the volunteers and donations.

DBA project management recently attended the Ground Breaking Ceremony on June 24th. The project is scheduled for completion in time for Veterans Day in November.

Drainage Improvements Added to Remote Access

04 Jun 2019/in , , /by

Beginning in June, 2015 and DBA’s first contract with Salt River Project at Horse Mesa Dam, DBA continues to support Salt River Project on maintaining safe access from the Apache Trail down to the dam. Our first project the Rock Debris Talus Stabilization project stabilized the rock face above the employee parking area and the main access to the dam. Since, then, DBA has embarked on several projects along the roadway to provide safer travel for dam engineers and suppliers driving to the site.

On April 4, 2019, DBA was once again awarded a contract for an additional $269,533.00 to improve drainage along the access roadway. This included excavation for and new construction of curb, gutters, valley gutters, and shotcrete spillways along both the Main Access Road and the road leading to the Man Camp.

Total quantities included:

450 SF of Valley Gutter; 1,195 LF of Concrete Curbing; 418 SF of Shotcrete Applications; 1,318 LF of Rebar; and 146 Each of #8 Bar Anchors

Salt River Recreation Area Gets Bridge Improvements

22 May 2019/in , , /by

Through DBA’s Job Order Contract with the Maricopa County Department of Transportation (MCDOT) for Bridge Deck Repairs, we were recently awarded a job order to complete necessary improvements to the bridge across the Salt River along Bush Highway.  The bridge is heavily used for camping, boating, tubing, and picnicking along the Salt River Recreational Area near Apache Junction.

Over time, the bridge had worn out the bearing pads under the deck and they were slipping out of place at one end of the bridge.  DBA drilled holes through the bridge diaphragms to get to the bearing pads.  We utilized a system for jacking up the entire deck at one end to replace all of the bearing pads (a total of 6).  After the new pads were put in place, DBA crews began the process of placing an Epoxy seal on the deck (closing one half of the 4-lane bridge at time in order to allow traffic to continue to flow).
