Project Description

Greater Rochester International Airport Construction of Doppler VOR/DME Facility

DY Consultants was tasked to provide project management, engineering, and construction management to remove a VORTAC and replace it with a Doppler VOR/DME Facility in a new location at Greater Rochester International Airport, in Rochester, New York. The design included an FAA-standard VOR/DME equipment building, a 120-foot diameter free-standing steel counterpoise with steel grating decking, and all required site utilities for the Doppler VOR/DME Facility.

 


Capital City Airport Medium-Intensity Approach Lighting System with Runway Alignment Indicator Lights

Due to the failing infrastructure of the existing approach lighting system for Runway 8 at Capital City Airport, Susquehanna Area Regional Airport Authority (SARAA) officials decided to replace the existing system. The replacement of the Medium-intensity Approach Lighting System with Runway Alignment Indicator Lights (MALSR) resulted in lower minimum visibility requirements and increased the number operations by better-equipped aircraft. DY Consultants acted as a sub-consultant to Urban Engineers for this project, which consisted of replacing the existing Simplified Short Approach Lighting System with Sequenced Flashers (SSALSF) with a MALSR. The project was coordinated with the Runway Safety Area Study (RSA). The responsibilities of DY Consultants included lighting station and shelter-siting coordination with safety area improvements; designs for new light bar structures with steady-burning light bars, sequenced flasher lights, or both; electrical load analysis of the MALSR system requirements; recommendations for rehabilitation, replacement of existing structures, or both; and site preparation and grading, with specific attention to equipment within and adjacent to the runway safety area.

 


Bandaranaike International Airport Approach Lighting System

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 airside 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.
