The National Park Service’s revitalization of Independence Mall included numerous building additions as well as relandscaping the two-block long plaza fronting Independence Hall. An existing multi-level underground parking garage that previously supported two feet of landscaping and light paving loads was altered to accommodate grade changes of seven feet or more.
CVM’s structural group developed a reinforced concrete grid structure to span across the existing garage roof deck level, bearing only column and girder locations. The grid provided flexibility in locating trees and provided the base for future café construction. CVM also provided envelope consulting services related to the below grade waterproofing systems for the program.
