Jet Bridge Replacement Program
Burns & McDonnell was responsible for verifying the aircraft parking layouts and designing the associated civil infrastructure improvements at Delta Air Lines Terminals 2 and 3. The overall project covered 26 gates and includes relocating aircraft parking positions, fuel lines, storm drainage structures, pavement removal and replacement, aircraft layout striping, electrical, mechanical, and structural foundations.
Burns & McDonnell analyzed the proposed aircraft parking layout for compliance with new requirements and the client’s objectives. In addition to the aircraft layout and maneuvering analysis, Burns & McDonnell designed the necessary pavement modifications for the relocated fuel lines, fuel pits and storm drainage improvements.
Burns & McDonnell performed a review of the existing apron pavements around Terminals 2 and 3. A study was prepared detailing the existing condition, surface drainage overview, material types. Pavement design involved determining the critical aircraft, reviewing the soils evaluation report, and calculating the pavement section to comply with the Port Authority requirements.
These services also included modifying the existing 400-hertz and preconditioned air systems and demolition of existing passenger boarding bridges and foundations.
Burns & McDonnell was responsible for pavement rehabilitation of existing asphalt pavement for Delta Air Lines at LaGuardia International Airport. The project included pavement demolition, repair of existing catch basins, design of PCC hardstands at seven Delta Gates, and aircraft pavement marking. Improvements to the drainage system, including milling and overlaying of asphalt pavement were also made.
Much of the apron area had become rutted and settlement created unsatisfactory slopes. The existing grade was manipulated to improve the grade in the area of the apron.
The project was carefully phased during construction to minimize the impact on daily operations.
Taxilane Lima-Alpha Reconstruction
Serving more than 45 flights a day, apron Taxilane Lima-Alpha is a vital link to 12 gates between Terminals 2 and 3 at JFK International Airport. The asphalt concrete portions of the taxilane were severely distressed. Portland cement concrete portions of the surrounding apron consisted of shattered and severely spalled slabs. In late fall 1998, Phase I of the reconstruction of the taxilane was completed in 20 working nights. The amount of portland cement concrete pavement constructed was approximately 3700 sy.
After considering several options, the final decision was to use very high early strength concrete for the taxilane pavement. In cooperation with the tenant airline, the project was uniquely phased for rapid reconstruction. A complete cycle of demolition, subgrade and base preparation, dowel bar installation, portland cement concrete placement, initial cure, and transition pavement were completed each night. The construction occurred between daily periods of major flight operations.
The coordination between construction and airline operations, along with the use of high-performance concrete, allowed a critical portion of apron Taxilane Lima-Alpha to be reconstructed with minimal impact on airline operations.
