Kapur & Associates completed several projects as part of O’Hare International Airport’s landmark $6.6 billion modernization plan.
The North Traffic Control Tower, a 245-ft concrete structure with a 400 sq ft cab structure atop the tower and a 10,000 sq ft single story building was completely controlled horizontally and vertically by Kapur. Every level of forming and construction was verified by Kapur right up to the green roof atop the cab.
Kapur & Associates, Inc. performed as-built surveys for United Airlines at multiple gates throughout O’Hare International Airport. Using 3D laser scanning equipment, Kapur quickly collected the existing field conditions and mapped the gates without disruption to airline services. Mapping was used for planning, re-design and re-stripping of the gate areas. All information was provided in paper and digital format. Laser scanning of this area allowed Kapur to quickly collect information without disrupting airline operations and without having to return to the site for additional information. This information was used for UAL Gate Optimization for gates B18 – B22 / C20-C30.
Part of O’Hare International Airport’s domestic service gates, Kapur & Associates, Inc. performed as-built surveys for American Airlines at Gate L-10. Using 3D laser scanning equipment, Kapur quickly mapped gates L-8 and L-10. Mapping was used for planning and re-stripping of the gate area. All information was provided in paper and digital format. Laser scanning of this area allowed Kapur to quickly collect information and not have to return to the project site. Existing utility survey information was under-laid onto the finished survey product.
The O'Hare Water Retention Base was another major project at the O'Hare International Airport. This 60ft diameter sunken pump station the concrete spillway and the intake structures were all controlled horizontally and vertically by Kapur starting with the primary and secondary caisson placement portion of the pump station. With tight tolerances for the sheet piling and alignment ring, accurate and dependable survey was a must. Elevation was also a primary concern because of the 'excavate and settle' construction method, where constant live grades were a necessity to ensure success.
