Bandaranaike International Airport Runway Overlay and Associated Works
DY Consultants is the Designer for the CATIC Design-Build Team of this large airfield redevelopment project at the Bandaranaike International Airport (BIA) in Sri Lanka. BIA is located within 30 minutes of Colombo, Sri Lanka’s capital and is the gate way to the country. Approximately 98% of the international traffic that goes through this country uses this airport.
This $60M USD contract is a comprehensive redevelopment of the air side facilities with the intention to upgrade the airport to ICAO Code F standards (FAA Group VI) while accommodating NLA such as the Airbus A-380 and to increase capacity to 45 operations per hour on this single runway airport. DY Consultants was the designer of the entire scope of the project, including; rehabilitating and expanding the runway, rehabilitating and expanding the parallel taxiway and the connecting taxiways, locating and constructing 4 new Rapid Exit Taxiways (RETs), constructing 2 new Bypass Taxiways, and installing an entire new Aeronautical Ground Lighting (AGL) system for the airfield with CAT II Approach Minimum requirements, including rehabilitating the runway’s Approach Lighting System (ALS).
The pavement evaluation, analysis and design required the utilization of standards from both the FAA and ICAO, including European agreements to mitigate for the A380 structural loading. The pavement analysis was comprehensive and utilized information generated by Visual Inspections, NDT Testing, Ground Penetrating Radar (GPR) and a Destructive Testing program that was developed and managed by DY.
Francis S. Gabreski Airport Runway Rehabilitation
DY Consultants developed a design solution to remedy the failing pavement section for Runway 6-24 (9,000 feet long x 150 feet wide) at Francis S. Gabreski Airport. The Air National Guard is a major tenant at the airport with a primary mission as a “rescue unit.” The runway also acts as an alternative site for emergency landings by the Space Shuttle. With this project, DY Consultants overcame the challenge of limited funding that was available from the FAA Airport Improvement Program (AIP). The recommendation for repair, based on extensive non-destructive testing (NDT) and soils investigation programs, was to rehabilitate the touchdown area of Runway 6 end (approximately 1,700 feet of the runway) through a technique known as “rubblizing.” This innovative technique allowed for a method to address failure of the existing joints and to control reflective cracking through to the proposed bituminous overlay, while maintaining the limited budget for the first phase of the design. The project was completed ahead of schedule with a total project savings of $1.5 million.
Hammonton Municipal Airport Runway 3-21 Rehabilitation
Runway 3-21 at the Hammonton Municipal Airport is a 3,602′ long by 75′ wide asphalt runway with Medium Intensity Runway Lights (MIRL), and a Precision Approach Path Indicator (PAPI) on each end. This non-precision instrument runway is the only runway at the Hammonton Municipal Airport. This runway is in need of rehabilitation from a functional standpoint, due to distresses on the surface course. The rehabilitation project primarily consists of repairing cracks, reconstructing portions of the runway that have failed, and an overlay of the runway with bituminous pavement. The intent is to provide a water tight pavement section that will defer further deterioration due to the environment, while minimizing disruption to the operations to the airports only runway.
Design Engineer. DY is presently in the early design stages of this project, developing construction documents in anticipation of soliciting bids for this FAA funded project. The Airport has an Airport Reference Code of B-I, which will be utilized in developing design criteria for this project, such as horizontal and vertical geometric parameters as outlined in FAA AC 150/5300-13. The structural analysis of the pavement design will use a mix of airplanes currently and projected for the airport as an important input to the analysis.
In addition, a safety and phasing plan and an operational plan will be prepared for the construction of this project. DY Consultants is very sensitive to the issues involved with designing and constructing projects on the Air Operations Area (AOA). We pride ourselves on developing clear and “easy to understand” operational plans.
Construction Manager. As the General Engineering Consultant (GEC) for Hammonton, DY is also responsible for the construction administration, engineering, and full time inspection of this project. Our staff of experienced airport inspectors will insure compliance to the plans and specifications, conformance to all approvals, and oversee the quality control and acceptance program.
