We were awarded the mechanical subcontract for this 138,000 square foot multi-story facility, which was certified LEED® Silver by the US Green Building Council. The project features natural ventilation throughout the office and common areas, steam heat exchangers for hydronic heating and potable hot water, two floors of biology laboratory space with a separate, isolated HVAC system, a vivarium with a steam-powered cage washer, an audiology lab space, and classroom space for approximately 750 students.

The mechanical space located on the roof includes chillers, air handlers, a humidifier, and extensive piping systems, while the basement-level mechanical space contains the steam pressure reducing station for heat exchangers used in building heating, domestic hot water, and all related ancillary equipment.

We also provided additional engineering support in designing provisions for the thermal expansion and contraction of the steam piping and combustion engine exhaust piping. In addition, WWU hired us to examine and recommend improvements to the fuel-oil storage and delivery system, and these recommendations were incorporated into the project. We completed the project on time and on budget, with no time-loss injuries.
