Engineering Infrastructure
Clients involved in building today’s complex buildings and structures, in congested urban areas or remote locations, require engineering surveys that are timely, accurate, and cost effective. Surveying establishes the framework upon which the project is based, from preliminary design through to completion of construction.

Deformation Monitoring
When you need to know when, where, and how much a natural object or man-made structure has moved, the Surveying Engineering Services Group has the instrumentation and specialized knowledge to provide the answer. Professional services and systems are available to provide accurate and timely information on the deformation status of a structure or object. Actual deformations can be compared against design assumptions and theoretical models or can be used to predict future performance.
