Runway 9L-27R
O’Hare International Airport, Chicago, Illinois
As a managing partner of O'Hare Runway Designers, LLC (ORD, LLC), Epstein provided Lead Engineering Design Services for Runway 9L-27R, the first of the new runways of the O'Hare Modernization Program at O'Hare International Airport. Runway 9L-27R is a new 7,500 foot long, 150 foot wide, Group V-capable Cat II/III runway, which opened on November 20, 2008. The project included a parallel taxiway and associated high-speed exits, a runway and taxiway underdrain system, pavement markings and NAVAIDS systems. The project was executed while the airport remained at full operation.
ORD, LLC was the Engineer of Record for the new runway. As the lead engineer for ORD, LLC Epstein was responsible for project management, conceptual design validation, design of mass grading, drainage erosion control, utilities and paving, cost estimating, QA/QC, and construction support. Epstein also provided coordination with the Department of Aviation, O’Hare Modernization Program, Federal Aviation Administration, Transportation Security Administration as well design teams responsible for other enabling projects at the airport.
Epstein’s civil engineers also prepared plans, profiles, details and specifications for the installation of over 4,300 L.F. of new ductile iron watermain pipe (12” – 24” Dia.) as part the 9L-27R runway project. This watermain serves the north airfield including cargo, guard post and fire protection facilities. The watermain system included tapping sleeves and valves for pressure connections, sectional and air release valves, fire hydrants, service connections and steel casing protection for installations below runways, taxiways and creeks. A cathodic protection system was installed to neutralize corrosion of the ductile iron pipe material.
