Kennedy International Airport (JFKIA) in New York, it became necessary to install utilities under existing runways and taxiways. Use of open-cut methods would have caused major disruptions to airport operations, with significant adverse economic consequences for the airport operator and the airlines. The Port Authority of New York and New Jersey (PANYNJ) determined that microtunneling was a safe alternative method for installing steel casings with a diameter of 0.9 m (3 ft) at a depth of 4.6 m (15 ft) under an active runway at JFKIA. All estimated direct costs were the same for similar-size microtunneling and open-cut projects. However, microtunneling significantly reduced construction time and caused minimal service disruptions as compared with open-cut techniques. Since 1991, PANYNJ has used microtunneling several times to install utilities for various projects at JFKIA, including a water main 404 m (1,325 ft) in length--a world record in 1994.
