NJ Treasury
Print Shop

NJ DPMC

In 1993, this building was renovated and occupied by the Department of the Treasury for use as a print shop. The critical functions of the Print Shop were threatened by condensation saturating and sweating through the chilled water pipe insulation and causing flooding and damage on the interior of the building. Crane Associates designed and replaced the existing chilled water pipe insulation and refurbished the roof top air handing units to secure the space from future damage and restore critical building operations.

PROJECT BRIEF

Upon completion of an investigatory survey and analysis Crane Associates crafted plans for re-insulation for the chilled water piping system. The roof-mounted chiller equipment at the facility was replaced around the year 2000, but heavy condensation and sweating caused severe damage to the inside of the building. In addition to the interior damage, accumulating condensate moisture in the rooftop air-handling equipment fostered heavy microbial growth and deterioration of the pipe insulation. Crane worked closely with administrative and construction personnel to ensure accurate execution of the project to agency and state standards and codes.

Upon beginning the project, Crane immediately tested all existing materials for the presence of hazardous materials. Removal and replacement of all chilled water pipe insulation commenced and removable insulation box covers were designed and installed for the existing chilled water pumps. The existing air handling equipment was tuned up and refurbished to extend the useful life of the system, while the RTU interior insulation was replaced and unit casings water and resealed. The roofing water damage was rectified and also sealed from further infiltration through the roof deck.
