COMMENTS
Soils in the project area consist of fill material near the ground surface. The fill is
comprised of sand silt and gravel with some rubble at depths varying between 4.5 to 18.5
feet. Fine to medium sands were encountered below the fill. Below this level varying
degrees of weathered bedrock were encountered. Groundwater was observed at depths
varying between 8.5 to 16.5 feet. Soils report recommendations include removing the
existing fill material in direct proportion to building height. For the multi-story
surgery infills, all fill material should be removed below the footings.
Based on the Uniform Building Code and the Connecticut Basic Building Code, building
structures are required to resist seismic forces. Connecticut is classified Zone 2Aby
UBC and Zone 2 by the Sate Code. Additions will be seismically isolated from existing
structures. Existing structures are not capable of meeting the current seismic code
requirements.
