DBA crews worked overnight on Monday to pour concrete at Luke AFB for the F-35 Fuel Offload Facility project. The project includes multiple underground structures and extensive Portland Cement Concrete paved (PCCP) areas for the loading and off-loading of jet fuel at the tank farm. This project is an addition to the project DBA constructed two years ago at the Base for new fuel tank foundations and concrete drives.
Yuma International Airport, Arizona – The 40th Street Air Cargo Apron and Taxiway project included grading and drainage improvements and complete PCCP placement of 7,000 square yards and placement of 7,745 square yards of asphalt pavement for the parking apron and taxiway.
DBA’s scope of work also included 2,300 linear feet of security fencing, the installation of taxiway edge reflectors and conduit for airfield lighting which included the coordination with airport utilities for the underground relocation of an existing primary electrical service.
Springerville Municipal Airport, Arizona – The Springerville Municipal Airport rehabilitation of Runway 3-21 and the Runway Safety Area included approximately 18,000 LF of asphalt pavement repairs, crack sealing, pave with FAA P-403 asphalt, and pavement markings.
This FAA funded project also included upgrading the Runway 21 end safety area to meet FAA design standards, which included grading, lighting and electrical upgrades, and new fence installation. As the project was being constructed, the Town of Springerville added the construction of a new Taxiway to the contract which was comprised of 6,700 SF of grading and asphalt paving and associated storm drain improvements, seeding, and pavement marking work.
Page Municipal Airport, Arizona – The airfield improvements for this project included the construction of:
Ancillary work associated with the project included:
Taxiway construction included rock excavation; 6,080 square yards of 2” thick asphalt paving; 6,410 square yards of new 9” crushed aggregate base course; three new concrete catch basins and storm drain pipe; and new taxiway edge markers.
The perimeter road consisted of the demolition and removal of the existing roadway; rock excavation; asphalt paving on ABC; storm drainage; rip-rap and striping. The electrical upgrades included 1,200 linear feet of trenching; conduit and wire installations; 250 linear feet of ductbank; installation of 52 L-853 edge markers; 14 edge lights; 3 new guidance signs (4 module and 2 module); replacement of 24 guidance sign panels and the installation of an 8” wind cone assembly.
This FAA AIP-funded project required a FOD secured worksite. Sweepers were utilized every work day and special construction site fencing was placed directly around each work site issues.
Marine Corps Air Station – Yuma – As part of the Indefinite Delivery Indefinite Quantity (IDIQ) Multiple Award Construction Contract (MACC) for Airfield Paving Projects with NAVFAC Southwest, DBA participated as a team member to remove and replace all existing concrete runway shoulders at Marine Corps Air Station – Yuma. The contract called for the repair and replacement of existing shoulders along Runways 17/35 and 8/26 at the Base and replacement with new concrete shoulders.
Grand Canyon Airport, Tusuyan, Arizona – The improvements for this project included the construction of a new entrance road from the highway into the airport property. Approximately 1,380 SY of PCCP at 8.5” thick was used for this roadway improvement at one of the busiest airports in the U.S. DBA’s scope of work also included the removal and replacement of concrete curb and gutter, valley gutters, and 32 concrete pads were included for the vertical adjustment of valves.
This FAA AIP-funded project required a FOD secured worksite. Sweepers were utilized every work day and special construction site fencing was placed directly around each work site to prevent FOD issues.
Gila Bend Municipal Airport, Arizona – DBA’s scope of work included:
The project also called for the construction of a raised, reinforced, concrete fuel island including concrete encased 2” diameter PVC ductwork for electrical distribution service, and new electrical pull boxes to service the new fuel pumps. Sustainable efforts were employed for the project by salvaging and rubbelizing the old AC pavement to be reused for the new aggregate base course.
The project was funded through the FAA using AIP funds and the lead designer was Gannett Fleming.
Coolidge Municipal Airport, AZ – The project scope included the removal and replacement of 7,400 SY of PCCP, removal and replacement of unstable subgrade, joint sawing and sealing, spall repairs, and striping. All work was completed with minimal impact to daily air traffic, fueling, Marine Corps sky diving training operations and monthly fly-in events.
As the project’s general contractor, DBA proposed a construction sequencing plan that allowed the airport to maintain normal airfield operations. A low slump concrete mix was submitted and approved that would achieve full design strength in seven days. All new concrete was then placed back in service in just one week, instead of during the initially planned four-week shutdown. These factors allowed for all PCCP placement to be done in a total of six weeks.
Unique Innovations: The issue of maintaining a level grade prior to the placement of PCCP was a project challenge due in part to replacing sections in an alternating sequence. DBA shop-fabricated a leveling/grading beam and attached it to the Gannon tractor, supplying an efficient way to grade a narrow stretch of taxiway and apron subgrade.
