Nearing Completion of Horse Mesa Dam Rockface Stabilization Project

26 Apr 2018/in , , , /by

Following on the footsteps of our successfully completed project for Salt River Project (SRP) at Mormon Flat Dam, DBA is under construction at another rockfall mitigation project at Horse Mesa Dam. The new project entitled, “Horse Mesa Dam Stabilization of Rock-Face at Water Line is one of the most complex projects we have undertaken for the Arizona utility. The contracts includes work at three separate locations for a total constructed value of nearly $2 million. It requires rock scaling and construction of a large retaining wall. The two other parts of the project include drainage improvements and the replacement of an existing wooden wall with a concrete wall above the dam access roadway. When complete, this will be DBA’s 10 project for SRP.

Pinal County Flood Mitigation Project a Big Success

11 Apr 2018/in , , , /by

Awarded in August, 2017, the Queen Valley Flood Mitigation Project Phase II involved the replacement of an existing pipe culvert under Sharon Drive at Queen Creek with a multi-barrel, cast-in-place box culvert.  The project was necessary because of erosion damage and scour conditions under the roadway after a summer monsoon.  In addition to constructing the new drainage structure, DBA was tasked with providing gabions along the banks leading up to the downstream culvert, repaving the roadway, striping, and general earthwork on both sides of the structure.  The project finished on time and within the original budget.

“Construction on the Queen Valley project went smoothly and DBA stepped up to the plate to get the work done efficiently and without any setbacks.  Through this project, we’ve developed a great working relationship with DBA and have the utmost trust and confidence in them.  We would be happy to use DBA again for future projects.”

DBA Employee Congratulated for “Good Catch”

28 Feb 2018/in , , /by

On Tuesday, February 27th, Tom Drysdale, President of DBA Construction presented Daniel Woolwine with a $50 bonus for his outstanding safety performance at our project in Texas.  Daniel was recently given praise from the onsite prime contractor’s Safety Representative for being “heads-up” and notifying every visitor to his job location of the hazards present.  This included presenting visitors with DBA’s Job Hazard Analysis (JHA) form to go over and sign as soon as they stepped on site.

The project is the Right-of-Way Clearing contract with Overland Contracting for the 69 kV Transmission Line Rebuild (Cedar Hill to Miles) for AEP Texas.  DBA is providing all of the earthwork along the 53 miles running through both Coke and Runnels counties in Central Texas.

Thank you, Daniel, for your commitment to safety.

DBA-Entergy: One of the Largest Projects in Louisiana

05 Jan 2018/in , , /by

Entergy is one of the largest utility companies in the United States.  Over the past five years, DBA has been contracted to complete sitework and right-of-way clearing for Entergy projects in Texas.  In 2017, we were contracted to participate on a design-build team to help build one of the largest utility / power transmission projects in the State of Louisiana.

The project, named Southwest Louisiana Improvement Project is a $100 million upgrade to the power grid for the people of Jeff Davis Parish.  The project started in December, 2017 and DBA’s portion is approximately 80% complete.  The entire project covers new and rebuilt power lines utilizing steel structures that can withstand up to 140 mph winds along a 60 mile stretch in the Parish and a large substation.

DBA’s $1.1 million scope of work includes:  clearing, grubbing, rough and fine grading the site for the substation (approximately 3.8 acres); importing fill, installing pipe, catch basins, building access roadways, paving, and placing rip-rap along slopes within the site for proper drainage.  The entire site required geogrid installation to stabilize the site and protect against erosion.  The substation is located just outside of Welsh, Louisiana (near Lake Charles).  This is one of two projects planned for DBA in Louisiana.

Central Arizona Project Awards Two Roads to DBA

26 Dec 2017/in , , , /by

Following on the footsteps of our original roadway construction and drainage project for the CAP in 2014, DBA was once again contracted by the Central Arizona Project to complete construction of two access roads to their communication towers.  Both roads provide vehicular access to CAP’s microwave communication towers that control the water distribution in the canal.

This year, our portion of the Helmet Peak job began where we left off with Phase I in 2014.  Our scope of work included roadway and drainage channel excavation through hard rock and the placement of 4″ PCCP (concrete paving) for a total 3,200 SF.  The second project was for Pan Quemado Peak near Marana, Arizona which required extensive rock hammering, placement of aggregate base, and PCCP (concrete paving) up the access road from the bottom to the top for a total of 7,400 SF.

Holiday Giving with DBA Employees

22 Dec 2017/in , /by

Annually, all DBA employees participate in some form of holiday charity event.  This year was no exception.  Employees received notices in their paychecks and in the employee newsletter that our charity of choice was the Phoenix Children’s Hospital Toy Bank.  Children and their families who are in the hospital during Christmas can enjoy the holiday even though they may be going through tough times with injuries or illnesses.  The hospital provided a list of preferred items for all age groups and DBA employees came through on a grand scale.  A total of $800.00 was collected and then the company did a dollar-for-dollar match.  The toys were purchased on Saturday, December 15th and delivered to the hospital on Monday, December 18th.

Work Continues at Second Salt River Project Dam

31 Oct 2017/in , , /by

Mormon Flat Dam on the Salt River holds back Canyon Lake and is downstream of the Horse Mesa Dam. In December, 2015, DBA was called out to an emergency at Mormon Flat to investigate a serious rockfall issue that had the potential to damage the dam’s main spillway. Minor repairs were executed and the existing debris was removed from the spillway. In early 2017, through their proposal process, DBA was once again contracted by Salt River Project to complete a permanent fix for the rockfall above the dam’s spillway. Several tons of fill were imported to the site to build up an area large enough to support to very large cranes in the spillway. Once the cranes were in place, DBA set about drilling out the loose debris for removal and anchoring a rock drape above the spillway to protect it from future damage. Winter rains and snowmelt is expected in late 2017, so crews are working fast to complete the repairs and demobilize the cranes prior to potential dam releases.

Repairs Complete at Texas Ranger Spring Training Site

05 Oct 2017/in , , , /by

The City of Surprise contracted with DBA to complete the replacement of concrete pavers throughout the concourse area at their Spring Training Stadium for the Texas Rangers. The original brick pavers were heaving in several locations and creating trip hazards. After Spring Training was over, DBA began working on removing the existing pavers, compacting the affected sections and replacing the pavers with decorative, stamped concrete pads that are doweled into the rest of the concrete flatwork. The stamped sections provide a “cobblestone” look and feel, resembling the concourses typical in historic baseball stadiums across the country.
