Dibble provided construction phase services for a new Automated Weather Observation Station (AWOS) to replace the previous system that had reached the end of its useful life.
A joint project between the Airport and Dibble solved a long-standing safety problem at Chandler Municipal Airport. An existing retention basin at the end of Runway 22L/4R drained so poorly that Airport staff had to pump stormwater out of the basin after each rain event, which usually lasted many days and attracted waterfowl, a significant threat to aircraft using the runway. After evaluating alternatives, Dibble designed a solution which connected the retention basin to an adjacent offsite retention basin/park. The Airport's basin was also re-graded and drywells were installed in both basins to ensure that the entire system emptied within FAA requirement of 36 hours.
Dibble prepared studies, design, plans, special provisions, specifications, quantities, and estimates and provided bid-phase services for the rehabilitation of the Falcon Ramp, located south the terminal and east of Runway 4R at the southwestern quadrant of the airfield. We evaluated the cost, value and need of changing the typical section for the current and future fleet of aircraft that utilizes the apron. We also evaluated how the apron transitions from the current open tie-down and t-shade configuration to a business/corporate use area, which required analysis of the capacity/movement needs and pavement strength requirements. Dibble designed a construction phase additive to expand the apron into the old aviation fuel facility that is adjacent to Tango One Aviation. A landside parking lot was designed as an additional bid alternative. We provided the bid alternatives during the construction phase to maximize the use of available funds.
The West Terminal project included a planning study that provided guidance for airport expansion as enplanements increase. Airline service grew quickly; shortly after the study, and in response to the surge in demand, a terminal annex was designed and constructed in a little over six months. Dibble provided engineering and CA services for the four-phase expansion that added 67,000 square feet and 10 additional gates to the West Terminal.
Pinal Airpark is a single-runway airport that serves hundreds of large, heavy aircraft every year. there was significant need to rehabilitate the pavement of Runway 12-30 to extend the life of the runway as much as possible. Dibble provided design, bid and full construction administration and inspection services for the rehabilitation of the 7,000 foot Runway 12-30 with the specific goal of extending the life of the runway as much as possible with the anticipated available construction budget. At the later stages of the design proves, a major airport tenant approached the County with information that two B-747s would need to land and depart a month ahead of the original plan. Dibble fast-tracked the remainder of the design, and worked with the contractor to successfully move up the project one month, reducing construction from 30 to 21 days.
Dibble provided design and bid-phase services for the reconstruction of approximately 5,300 SY of AC pavement along Taxiway ‘B2' from the Restaurant Apron to the entrance to the airfield hangars, and rehabilitation consisting of crack sealing and a thin mill-and-overlay of approximately 6,000 SY of AC pavement at the southern end of Taxiway ‘B2'. The project scope also consisted of reconstructing approximately 8,333 SY of AC pavement at the Runway 6R Overrun. The project included significant construction phasing evaluations, as well as performing geotechnical investigations and pavement design, developing construction plans and specifications for demolition (milling), paving, grading, and striping.
Dibble completed studies, design, and engineer's report, specifications, and construction plans to improve the Runway Safety Area for Runway 7R 25L from 600 feet to a FAA-compliant 1,000 feet. Work included designing one half-mile of new CSA on the north bank of the Salt River, grading the extended RSA, relocating the perimeter fence and road, coordinating with the FAA to relocate the Localizer, MALSRs, and associated infrastructure, conducting hydraulics and channelization in the Salt River, and designing approximately 1,700 feet of 84-inch storm drain.
Dibble completed studies, design, an engineer's report, specification, and construction plans for a 2,800-space remote parking lot serving the existing West Terminal and future East Terminal. Work included grading and drainage; stormwater detention; bus routes, stops and canopies; parking revenue control systems; pavement marking and parking lot directional signage; lighting, traffic evaluation and signal design for Ray Road; and bid phase services. The project also included airspace analysis evaluation (Part 77 and One-Engine Inoperative) versus parking lot lighting and canopies; along with fast-track modifications for the City of Mesa of the adjacent Ray Road construction plans for a median opening, turn lanes and intersection improvements to accommodate the parking lot entrance.
Dibble prepared analyses, plans, specifications, reports, quantities, estimates, bid-phase services, and is currently performing construction observation and administration for the installation of medium intensity runway lights (MIRL's), lighted runway signage, a rotating beacon, a new wind cone, a new electrical vault, 2-box Precision Approach Path Indicators (PAPI's), runway end identifier lights (REIL's), and all associated electrical infrastructure. PAPI siting based on the requirements of FAA AC 150/5340-30G was included in this project, as well as grading and drainage elements. This project also included updating San Manuel Airport's DBE Program.
