A 30,000 Sq. building required a complete retrofit of their natural gas piping. It also demanded the complete removal of 26 units (RTU, MUA’s Exhaust Fans etc….) which we re-installed once the job was completed. At the completion of the piping lay out and installation, the entire piping system was pressure tested for a minimum 24 hour period and inspected for leaks. Once assured all was in order, the gas lines were painted and the gas meters were opened and gas lines purged. Upon full completion of the job, it was inspected by the appropriate authorities and passed with flying colors!
