Huitt-Zollars was responsible for the relocation and improvement of Tatum Boulevard to a four-lane divided roadway with improved horizontal and vertical geometrics, and intersection improvements. The project required careful alignment design to minimize adverse impact to adjacent property owners. Drainage analysis was a key element in the initial study, primarily due to a proposed grade separation to accommodate cross traffic.
Huitt-Zollars developed construction documents to reconfigure approximately two miles of SR-87 from a four-lane undivided segment to a four-lane divided highway, the only undivided portion of the 80-mile highway. The project is characterized as a grade, drain and pavement project, requiring the construction of a new divided roadway, extension of existing CMPs and box culverts, pavement preservation, safety and drainage improvements, and native plant salvaging and seeding.
Huitt-Zollars provided survey, design, and construction administration services for several delivery orders that include preparation of drawings, specifications, and estimates for two new guard houses and associated traffic lane improvements; roadway milling and overlay; roadway shoulder upgrading and repairs; sanitary sewer upgrades; and upgrades to runway overruns, taxiways, and shoulders.
Huitt-Zollars provided full architectural and engineering design from design charrette to final bid documents (including construction drawings, specifications and design analysis). The disciplines included: civil, architecture, structural, mechanical, electrical, plumbing, fueling, telecommunications/data, security, and landscaping. The facility was designed to meet LEED Silver certification and the Federal Government mandated energy and water use reduction requirements.
Huitt-Zollars has provided drainage work associated with improvements and expansion of Marine Corps Air Station, in Yuma, Arizona, which is a joint-use airport with Yuma International Airport. Drainage analysis and design included stormwater retention basins in the infield between Taxiway I and Runway 17/35, between Taxiway A and 8/26, and at the intersection of Runways 8/26 and 17/35 at MCAS Yuma, Ordinance Access Roads Phases 1 and 2 and the entry road to the Cannon Air Defense Complex.
Huitt-Zollars provided civil engineering services to improve drainage facilities at Falcon Field Airport. The project included 700 linear feet of slotted drain; storm drain inlets; 15,000 linear feet of 18-inch to 48-inch storm drain along existing taxiways and existing roadways; and grading of a large drainage basin utilized to retain storm water runoff from the airport.
The Gila Bend Auxiliary Field Runway functions as an emergency landing option for military aircraft. The project scope included construction of a new 1,000-linear-foot concrete touchdown area at both runway ends, mill, and overlay for the remaining asphalt pavement, and construct asphalt shoulders along the new runway pavement. The total runway is 8,500 linear feet. Aircraft arresting gears are installed at both runway ends.
This project includes the construction of 2,170 linear feet of Taxiway C to infill from Taxiway C at Taxiway C3 easterly to Taxiway C at Taxiway C4. Also included was the construction of asphalt concrete aircraft parking aprons totaling approximately 50,000 SY. Connector Taxiway C4 is a new connector taxiway between Taxiway B and project Taxiway C West Infill. The new connector taxiway will facilitate use of the high speed exit from Runway 8-26.
Huitt-Zollars provided engineering design services for a 60-acre air cargo/corporate hangar site development. This included the the design of the aircraft parking apron and connecting taxiway, the storm drainage system, water utilities, and sanitary sewer utilities. Huitt-Zollars was also responsible for the design of all landside facilities.
Huitt-Zollars provided engineering design services for the reconstruction of 4,100-linear-foot of taxiway and associated improvements. Three 150-linear-foot-wide connector taxiways provide increased width to serve the new larger aircraft at the site. Approximately 88,000 SY of existing pavement was replaced with a total pavement thickness of 52 inches. Work also included the construction of two asphalt concrete aircraft parking aprons, totaling approximately 40,000 SY.
