PROJECT DETAILS
York College’s 240,000 sq. ft. sports facility requires a sophisticated HVAC system with 700 tons of cooling to support the various uses and large changes in cooling and heating for events. The mechanical room houses five large air handling units, two pool pack heat recovery units for humidity control of the natatorium, boilers, chillers and a cooling tower. The architectural firm's design created unusual HVAC time and space requirements. Specialty flooring required the central HVAC system to be operational for heat five months before project completion. The firm also designed a narrow penthouse mechanical room located on the 3rd floor and extending the length of the facility’s axis.A two-month preplanning process included the foreman, project manager and General Contractor. The team created a detailed Man Loaded schedule and a sequence of activities for phased startup by priority. This kept the man power loading to a manageable, productive number while meeting the required goal for heat. Productivity measurement on quantities installed bases was set up to feedback on progress. The mechanical room space constraints for rigging in large equipment and running ductwork and piping was equally challenging. Special emphasis on the coordination drawings and check reviews helped overcome constraints and maximize the prefabrication of piping and fabrication of ductwork.
