Optical Monitoring

Optical monitoring, or Horizontal and Vertical Controls, provide a calculated and analytical approach to determine structural documentation and potential change during critical construction activities. Optical Monitoring entails the installation of optical monitoring devices (prisms, or prismatic sheets) on the structures in question, and a periodic measurment of the location of the devices on the structure with a calibrated survey instrument. The Big Apple Group provides optical monitoring during each phase of construction.

Collection and reviewing this data helps the engineer evaluate the performance of the specified construction project, allowing for advanced warning and implementation of corrective measures to be completed, if needed, prior to any catastrophic failures.
