CNA has extensive experience in performing monitoring surveys for walls and structures during construction and land mass monitoring of large areas. The relative location of a structure, wall, landmass or any other object can be monitored for movement both horizontally and vertically with respect to a fixed location of Control Points. This type of survey is utilized generally to determine if existing improvements are moving during the course of construction or from underlying soils conditions which cause for land movement. CNA works with design professionals to determine the project requirements throughout the duration of a project.
