McKenney’s replaced chilled water risers in high-rise towers without compromising cooling system performance.

THE CHALLENGE

New chilled water risers were required for large high-rise condominium towers. McKenney’s needed to install new piping without interrupting existing building cooling system operations. In addition, the team had to spread the cost of the project over three years to match the budget of the building’s owner.

THE SOLUTION

The McKenney’s team chose an alternate location to install the new chilled water risers in order to simplify the transition to the new cooling system in a cost-efficient, convenient manner for the homeowners. Two or three units were connected to the new risers at a time to accommodate the project’s unique scheduling needs. Riser sections were prefabricated at McKenney’s campus facility to streamline installation. Once all units were connected, the old risers were capped, drained and abandoned.

THE RESULTS

Using a phased approach, the building owner’s unique budgetary and schedule requirements were met with minimal impact to homeowners during installation.
