Selected by traditional design-bid-build methods, DBA is completing construction of a new Multi-Use Path in Wellton, Arizona connecting downtown to Butterfield Park with a new pedestrian bridge and path improvements crossing the Coyote Wash. The project required earthwork, the construction of concrete bridge foundations, asphalt path construction and concrete approaches. Ribbon cutting ceremony is scheduled for early January.
Currently, Job Order Contractors for the City of Surprise, DBA Construction took part in the volunteer construction of the Veteran’s Reflection Circle (a memorial to fallen hero SFC Brian Mancini). Today, Veteran’s Day 2019 was the official ribbon cutting ceremony. Local dignitaries presided over the event and U.S. Representative Debbie Lesko was in attendance along with approximately 450 Surprise residents, veterans, and City employees. DBA’s participation in the project was recognized at an earlier Dedication Ceremony at City Hall and our name is prominently displayed on a permanent placard at the memorial.
DBA Construction, Inc. participated this year in the 21st Annual Arizona Rural Transportation Summit held at the Casino del Sol in Tucson last week. The event took place October 16-18 and was very well attended by ADOT personnel and transportation leadership from the rural areas including towns and cities from Yuma to the Navajo Nation and from the Mohave County to Bisbee. DBA was on hand as a Copper sponsor (first time this year) and was allowed to showcase our capabilities and share in the fun.
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.
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.
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.
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.
This Federally-funded project was contracted through the Arizona Department of Transportation for the City of Globe.
The project was to complete both Oak Street from Ash Street (US-60) to Hill Street and Hill Street from Oak to Ash in the historic downtown area. DBA’s scope of work included:
The $577,665 project was completed in two phases due to the winter shutdown.
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.
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.
