This document is the Laguardia Airport Renovation Case Study. Port Authority in New York, required N-12 and HP Storm installation during rebuild of airport discussed.

The $8 billion rebuilding of LaGuardia airport was the creation of a state-of-art facility in that new terminals, roads, parking lots, garages, retail shops and restaurants were built. Along with the above ground work, an underground stormwater drainage system was built on the airside and land side.

Two ADS thermoplastic pipes - N-12 and HP Storm - were chosen for the stormwater drainage system. On the airside, which involves taxiways and de-icing pads, over 23,000’ (7,010 m) of HP Storm pipe was utilized. For the land side, 25,000’ (7,620 m) of N-12 pipe was used for access roads, parking lots and pedestrian areas.

The choice of ADS pipe over RCP was a cost savings for the project. Because of its light weight and longer lengths, it was estimated the installation was cut in half compared to what it would have taken to use RCP. In addition, the ADS pipe cut deliveries to the busy airport by 33% as the smaller diameter pipe was nested in larger diameter pipe allowing more linear feet to be delivered on each truckload.

The installation was done in 2017 using 23,000’ (7,010 m) of 15”-60” (375-1500 mm) HP Storm pipe and 25,000’ (7,620 m) of 12”-60” (300-1500 mm) N-12® pipe.

Photographs of the project are included.
