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.

State Route 79 Box Culvert Extensions Nearly Complete

21 Jul 2017/in , , , /by

The project required the extension of existing box culverts at eight separate locations along State Route 79 between Florence and Oracle Junction (mile posts 122 to 124). The existing structures had suffered serious damage from recent flooding which included major deterioration of substructures and wing walls. The project was completed in phases, working one side of the highway at a time and rolling traffic control devices from one site to the next. This was done to maintain traffic on the highway during construction without interruption. The project was awarded under a design-bid-build contract with the Arizona Department of Transportation.

Hypochlorite Trench Rebuild Projects Earns AGC Award

29 Jun 2017/in , , /by

Palo Verde Nuclear Generating Station hired DBA to complete a rebuild of their Make-up / Blowdown Structures Hypochlorite Trench and pipeline.  DBA’s scope of work included the construction of a chemical by-pass system to hold the chemicals temporarily during construction of the new concrete vaults without disruption to the existing cooling system at the plant.  Demolition of the 30-year old concrete vaults carrying the hypochlorite system in pipes within the vaults was completed after the bypass was in place and tested for leaks.  DBA crews excavated, graded, and compacted two large trenches (333 LF and 167 LF), outfitting the trenches with pre-cast vaults and cast-in-place closure pours to seal the system.   The project recently received the 2016 Build Arizona Award from the Arizona Chapter of the Associated General Contractors for Excellence in Project Management, Meeting the Challenge of a Difficult Job, Contractor’s Innovation in Construction Technique or Materials, Sensitivity to the Environment, Client Service, Safety and Contractor’s Contribution to the Community.

The $1.3 million rebuild project also included:

  • Layout alignment of pipe bypass system
  • Installation of temporary fencing around immediate work site
  • Construction of by-pass lines
  • Installation and welding of pre-fabricated pipe supports
  • Support existing in-place utilities adjacent to the new trenches
  • Use sand as bedding for new trench bed
  • Remove and disassemble existing pipe for proper disposal
  • Reconstruct concrete sidewalks and approach slabs
  • Patch asphalt paving

Community Investment Project Provides Real Value

21 Jun 2017/in , , /by

Recently, DBA Construction, together with the City of Coolidge, the Coolidge Youth Coalition, and Cenpatico Integrated Care celebrated their community investment project with a ribbon-cutting ceremony near Coolidge High School.  Added to DBA’s scope of work for the reconstruction of Main Street and Vah Ki Inn Road, DBA was tasked with constructing new sidewalk, ADA ramps and driveway crossings in front of the City’s Pool.  The added scope was funded by a grant from Cenpatico Integrated Care which was requested by the Coolidge Youth Coalition.  The newly constructed concrete sidewalk and ramps replaced an area at the corner of Northern Avenue and 9th Street near the high school that was previously a dirt path.  The community’s Youth Coalition saw a need to address the issue for the safety of the City’s youth.  The ribbon-cutting ceremony was attended by DBA staff (Matt Woolwine, Briselda Guerrero, Kevin Trail, and Jeanne Sapon), members of the Youth Coalition, Cenpatico, the City’s Mayor, City Councilmembers, and the Fire Chief.

DBA Completes Roadway Upgrades for Salt River Project

12 Jun 2017/in , , /by

Following several important rock fall mitigation projects, drainage improvements, and paving the road from the dam to the man camp for SRP at Horse Mesa Dam, DBA recently completed the 4.2 miles of roadway from SRP’s main gate down to the dam through the canyon.  Through several discussions with Salt River Project engineering personnel and multiple cost models for the roadway construction, DBA suggested a soil cement solution to stabilize the roadway down to the dam.  The project will be completed this week.  Brush fires along SR-77 near Tortilla Flat curtailed construction for a short period of time earlier this month, but once cleared by the Forest Service, DBA crews returned to the job site and completed the job.  Total constructed value of this project was $1,362,230.00 which included grading, compacting and placement of the soil cement.

This portion of the work completed for SRP at Horse Mesa Dam is a small part of the project overall which included the building of a 60′ tall gabion wall with a 500 KJ fence at the top to stabilize a talus 1:1 slope; adding a 100 KJ fence to another area above the upper dam road; rock excavation for an addition to the Maintenance Building on site; drainage improvements, and AC paving the road to the man camp.

24 May 2017/in , , /by

P-83 is Peoria’s Entertainment District and a major focal point for the City. Transforming the corridor into a “Gateway” for the City along 83rd Avenue, DBA was contracted to complete construction of aesthetic treatments to the bridge over Skunk Creek at the south end of the project. Scope of work includes removal and replacement of bridge end treatments, barriers, guardrail, curb and gutter, and pedestrian railings to help identify the bridge with the rest of the aesthetic treatments along the corridor.  New sidewalks were also constructed, a new raised median with landscaping and lighted, blue glass-filled gabions to continue the iconic “look”.  The Skunk Creek Bridge portion of the P-83 Improvements was part of Phase II in a 3-phase enhancement project.
