Summary of Field Testing
WXYZ Building in Chicago 17 September 2003
1886 Robinson Fire Insurance Map
Excavations began at 6:30 AM this morning. Utility
companies were notified that we would be digging. SBC Ameritech, Com
Ed, and People Gas responded that there were no buried utilities in the
project area.
Area of excavation is highlighted in Pink above the number 6.
Note that lots 5 and 10 on the west side contained structures along
Roosevelt Road. We placed a 500 foot excavation trench (city blocks
are approximately 600 feet long)along the back of the lots - there is some
suggestion that structures were located along the lot line immediately
adjacent to the alley. Note that lots are approximately 25 feet wide.
We did encounter concrete foundation in lots 12 East and 12 West.
Average depth of trench - 65 inches.
