The South Green project was a large underground steam/condensate and chilled water project for the University of Delaware. This was a fast-paced project through the heart of campus, requiring every move to be carefully thought out and meticulously planned in order to minimize the disruption to student life.
To save two historic buildings from demolition, Corrado Construction came up with a twofold approach to go under the buildings by using both jack and bore as well as hand tunneling. Chilled water went under one building using jack and bore, while the second structure lacked room for this conventional method and careful hand tunneling was the only viable option for installing the steam and condensate.
Corrado had to restore the Green completely – mid-project – to accommodate the University’s 2019 Graduation and Alumni Weekend, patching up the Green as if never there between the first and second phases of the project.
To keep to the project timeline, the need arose to open up a substantial amount of trenching through the winter months. Keeping the trenches protected became paramount and Corrado sequenced the work to protect the pipe subgrade, thereby minimizing adverse weather affects.
Corrado worked closely with the University to understand and protect the trees and root systems in the Roselle Grove, a particularly sensitive natural area on the UD Campus.
