Square Lake Road is one of the main east-west roadways in the northern Detroit suburbs. Adjacent to the I-75 ramp connection, Square Lake Road bridges the Grand Trunk Western Railroad tracks. At this point, the roadway consists of three lanes in each direction.


WJE developed a monitoring program to ensure that the water main's vibration and settlement during construction did not exceed the limits specified by the DWSD. The vibration monitoring utilized a remotely operated seismograph to minimize the field labor costs, the data from which was downloaded twice a day. Settlement monitoring was also performed by installing telltales and measuring their elevations three times per week with surveying equipment. WJE's monitoring program confirmed that excessive settlement or vibration did not occur during bridge demolition and pile driving operations of the new construction.
