Claitman Engineering provided Mechanical, Electrical, and Plumbing Design Services for the renovation and addition to the existing St. Joseph’s Catholic Church in O'Hara Township, Pennsylvania.  The project included a new sanctuary addition, as well as, renovations to the existing facility.  The new sanctuary is fully conditioned with a preset dimming system for all lighting.

Claitman Engineering was assigned the task of designing an Air Conditioning System for the Cathedral's 100th Anniversary.  The Bishop had only two requirements:  1) The system must be “invisible” to maintain the architectural integrity and religious significance of the 100 year old structure; 2) The system must be “Silent”.  Claitman Engineering achieved both.  The supply air registers were built into six of the existing enclosed confessionals.  To hide the return grilles, wood work was removed from the rear of the sacristy and relocated inward three feet to allow room for a shaft without the perception of being added onto the building.  The 30 foot long air cooled chiller was hidden on the site by building a pit that resembled one of the Cathedral's existing area wells.  The equipment was lowered into the pit and out of sight.  By working closely with the Design Team and the Diocese, we were able to satisfy both the Bishop's and Architect's noise concerns.  The result is a 100 year old air conditioned Cathedral that has maintained its aesthetics and integrity.
