To support a new surgical pavilion, Heffron installed miles of underground high-pressure steam, pumped condensate, and chilled water piping connecting the new building to the existing campus loop system. Some pipe sections reached 24 inches in diameter at depths up to 17 feet, and a temporary suspended loop maintained circulation throughout construction.

The project ran alongside active hospital work on a constrained site, requiring engineered shoring, carefully managed shutdowns, and fast response to field conditions — all without disrupting the operations above.
