Introduction
New York State’s largest healthcare provider operates 23 hospitals and cares for 8 million patients across the state. The provider was building a new 110,000 square foot laboratory facility on Long Island that required best in class mechanical equipment, from new chillers, boilers, fan coil units, and custom air handling units (AHUs), including specialty equipment serving the lab area such as snorkels and fume hoods.
Challenges
This was a particularly complex project due to the size and nature of the facility; proper air quality and temperature is vital for safe healthcare operations. For this project, adherence to a narrow project timeline and stringent safety standards were taken on with the utmost commitment. The new cooling system needed to handle over 400 tons of cooling and 88,000 Cubic Feet per Minute (CFM) of exhaust air to effectively cool the facility, while meeting numerous specialty requirements for critical equipment rooms.
Solution
Donnelly managed the installation of four large rooftop units, each weighing 100,000 pounds, on top of the new building. The team coordinated an all-terrain mobile crane, with a maximum lift capacity of 500 tons to rig and hoist the equipment on the rooftop. The process took four days to get this equipment set in place and assembled on the roof.
Results
Donnelly saved the client costs by finishing the project under budget and within established timelines. 3D AutoCAD drafting and BIM modeling ensured successful logistics planning and collaboration between construction trades. All equipment was successfully installed and commissioned, including specialty systems for critical equipment rooms. The client was able to minimize disruptions to their daily operations.
