The project required replacing all the steel piping, panel & devices, and storage tanks (total 2000 lbs) for 3 systems in the computer centre located in the Hodgson Building.

Steel piping up to 3” diameter was replaced above the ceiling and below the floor throughout the computer centre without disturbing on-going computer operations.

The contract document’s requirement for dust containment and no interruption to computer operations was achieved with no complaints from the operators.

HINT: When specifying a new or replacement system, we suggest you include a requirement for room integrity testing, as well as work that may be required to seal the room to meet the requirements or the AHJ, the manufacturer and of the requirements of NFPA 2001.
