DBA Constructs Two New Shooting Ranges

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.

Scottsdale Gets Extension of Multi-Use Path

Working directly adjacent to Scottsdale’s City Hall Complex which includes City Hall, Capital Project Management, Engineering, Development Services, the Main Library and the Center for the Arts, DBA was contracted through our Job Order Contract to build out the multi-use path from the Indian Bend Wash (east of Miller Road) down Second Street to 75th Street where it connects to the downtown complex.

The job order included widening the existing sidewalk from 6′ wide to 12′ wide (creating the multi-use path) to accommodate bicycles, skateboards, Segways and pedestrians. The extension connects the park at Indian Bend Wash with the downtown buildings and the library.

Extensive communication was required to coordinate construction efforts with adjacent homeowners and businesses along the route and traffic control measures were also very important to maintain access and protect the driving public along busy Miller Road. DBA’s scope of work included:

> Demolition of existing pavement and concrete flatwork
> Subgrade preparation
> New A/C paving
> New concrete curb, gutter, driveways, and the multi-use path
> New ADA ramps
> Manhole adjustments
> New catch basins
> Trenching for new electrical conduit
> New masonry retaining wall at the library
> Storm drain connections
> Relocation of control cabinets and traffic signal boxes
> New signage and striping/markings
> New street lights/signal poles/mast arms
> Minor landscaping and placement of decomposed granite
> Replacement of the existing stairs with an ADA-compliant ramp from the street level to the garden level at the City’s park

Multiple areas required special attention and “field fit” minor design services were included to work around existing irrigation piping and traffic signal poles.
