Introduction
A New, State-of-the-Art Healthcare Facility
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.
Customer Challenges
Ensuring Proper Air Quality & Temperature for Safe Healthcare Operations
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.
Budget, Design, Build, & Operate
Donnelly Mechanical was brought into the project by the general contractor during the budget phase. By coming into this project early and putting in the at-risk work upfront, Donnelly was effective in collaborating successfully with many different trade partners throughout the process.
In the Design phase, Donnelly assisted with the value engineering in conjunction with the general contractor. Finally, Donnelly was brought on to build the project, where they coordinated amongst various sheet metal, mechanical piping, plumbing, fire protection, and electrical trades to ensure that they executed the design intent.
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.
