Subject: [CPEO-MEF] RADON: Nellis Air Force Base (NV) mitigates radon intrusion in new construction
Air Base Tries Radon Solution

Southern Nevada's Nellis Air Force Base is trimming construction costs of a new child development center by nearly 4% by using a unique aerated plastic-riser foundation system.

Cobblestone Construction, Las Vegas, broke ground on the $7.2-million design-build project in August 2010 and later discovered that the six- acre site along the northwest edge of the base was contaminated with radon.

The 26,000-sq-ft block building consequently required a gas ventilation system, which typically comprises a vapor barrier consisting of a membrane of washed rocks and liquid as well as perforated pipe and fans. Wright Engineers, Las Vegas, proposed a cost-effective alternative called Cupolex, which saved $10.97 per sq ft, or $285,000 in materials.
