Turning a site formerly populated with single-family housing into a major health sciences research campus takes a significant investment in infrastructure design and construction.

Challenge

We needed to develop an appropriately sized and strategically aligned network of tunnels and piping to serve both near- and long-term building needs, and we had to add new heating and cooling production systems into the very limited and valuable real estate of the existing campus utility plant sites.  Finally, all of this had to be done safely and without disruption to traffic and other critical campus functions.

Solution

Working closely with municipal agencies, GLHN designed a large-diameter piping and tunnel system to fit beneath existing roadways and to connect multiple sources of heating, cooling, and water. We designed new high-efficiency cooling and heating equipment for installation on the compact site. These included fast-acting, low mass steam boilers and water chillers specified to be capable of future conversion to turbine drive. Constructing the new plant expansion and cooling towers on the site involved close collaboration among a team of engineers, operators, the construction manager at risk, and trade partners.
