For the general contractors that built the new $ 20 million Avalon elementary school it was all about the numbers. For students, teachers and the school’s administrative staff it was more about comfort. Either way, leaks in the building’s ductwork were keeping the school’s state-of -the-art geo-thermal heating system from running efficiently. Until those leaks were sealed and the contractors were able to meet system specifications, their job was not complete...office and classrooms would remain unacceptably cold through the upcoming winter months.
