Precise and Higher Order Surveys

Underground, Oxford St, Halifax NSIn the planning stages of a project, Thompson Conn’s staff review project requirements and the integrity of the existing coordinate control in the subject area.  In most cases TCL will perform a high order GPS static survey to establish precise x, y, z coordinate control points in and around the project area.  These control networks are planned in detail with respect to observation time, suitability of control point locations, strength of figure and are subject to rigorous quality assurance and control.

These high order control networks then form the basis for all survey and construction activity.  As control is required it is re-established from the original TCL control fabric to ensure quality, repeatability and precision.
