We monitor structures, walls and slopes for movement during heavy civil construction. Our reporting threshold is 0.005 ft (1/16″), and crews get the report in time to act the same day.

We take repeat epochs on structures, walls and slopes during construction. We compare each epoch to tolerance and report it so crews can act the same day.
At the El Portal and Tuolumne Meadows treatment plants, we did structural deformation monitoring with a 0.005 ft (1/16″) reporting threshold. We also monitored a retaining wall to the same threshold.
On both plants, we also set the survey control and did the construction layout. The plants include structural steel and precast buildings.
Control and construction layout for a national contractor on two Yosemite wastewater plants, including structural steel and precast buildings, plus deformation monitoring with a 0.005 ft (1/16″) reporting threshold.
