115,000 square feet
This project consisted of replacing the existing hydronic heating water boiler plant with a new, high efficiency condensing water boiler plant, as well as replacing seven rooftop air handling unit systems that ranged in size from 20 tons to 105 tons. The new boiler plant provides the same heating capacity with less natural gas. PTA developed the overall construction budget for the HVAC upgrade and developed a “suggested sequence of work” to ensure that all work would be completed before August of 2016. During the design phase, PTA worked with a local rigging contractor to develop a “proposed rigging plan” that could be budgeted into the project, thus ensuring a practical project schedule and rooftop air handling unit shutdown period. All work was scheduled to be completed in a manner that maintained building occupancy throughout the entire construction period.
