Bristol-Myers Squibb’s Research & Development Facility
in Lawrenceville is a 273-acre campus served by a central heating
and cooling system from a central plant. Syska Hennessy prepared
a utility master plan to determine the upgrade required for the
new buildings.
The master plan evaluated expanding the existing system to a multiple
plant system versus building a new central plant to serve the entire
campus. Squibb selected the multiple plant scheme, but later reverted
to the central plant system after the design of multiple plant
was completed.
Syska Hennessy completed the design of the new central utility
plant and distribution system, which included the following:
- Four 3,800-ton centrifugal chillers - two electric
driven and two high pressure steam (250 psig) turbine driven
- Four
3,800-ton remotely located masonry shell cooling towers including
underground piping
- New tunnel chilled water distribution system
to the new site buildings, including approximately 2,000 ft.
of chilled water piping (up
to 30 in.)
- Interconnection with the existing chilled water distribution
system
- Three 70,000 lb/hr and one 40,000 lb/hr 250 psig sat.)
steam boilers
- One 1,200 kW diesel generator for utility plant
emergency power
- Four 3,880 kW gas turbine generators for site
electrical requirements with heat recovery boilers for chillers
plant and site thermal
requirements
- Four 250 scfm@150 psig air compressors
Syska Hennessy has continued to assist Squibb in integrating the
existing systems into the central system and decommissioning the
original central plant. The original high temperature hot water
boilers were retired and replaced with steam from the new central
plant.
