Engineering / Utilities

We are open to joint ventures and partnership with engineering firms and oil and gas utilities. Our team is made up of experienced Land Surveyors and GIS professionals who have collaborated with a number of groups in the past to provide valuable data and land surveys for large-scale projects.

In addition to the individual surveys in this section, have a look at the Maritime and Northeast Pipeline project for an example of one of our past partnerships.

Aerial Survey & Photo Control

Thompson Conn, in partnership with Eastcan Geomatics, is able to provide our clients with complete aerial survey service. Our team is able to assist clients from the planning stages, defining flight lines and ground control, to the final delivery of structured data in various GIS formats. 


Together, with our partner companies, we are able to provide aerial photography (digital and film) plus LiDAR (light detection and ranging) data, followed by photogrammetric data collection, ortho-rectified imagery and database development.

Our services also include the establishment of ground control targets to be used in aerial triangulation (AT) adjustments. We are able to provide reference stations for the adjustment of airborne GPS values for photographic and LiDAR data collection. 


Alternatively, we are able to establish photo identifiable ground control points on existing imagery.

Deformation Monitoring

Deformation Monitoring is the process of measuring points or surfaces with the use of Total Stations or Scanning Survey Instruments. These measurements are then compared with previous measurement sets to determine movement of the structure. Structures monitored include retaining walls, bridges, columns, foundations, expansion joints and piers.


Thompson Conn has carried out deformation monitoring surveys at the Canadian Gypsum Wharf in Little Narrows, Cape Breton, the wall at the Halifax Parade Square, the exterior face of the Ralston Building in Halifax and the Angus L. MacDonald Bridge cable bent pier base.

Hydrographic Surveys

Thompson Conn can provide underwater data for stream and river bed profiles, lake and small harbour depths, and location of shoreline information such as the ordinary high water mark. This information can be used for various development and planning purposes for bridge construction, land use and wetland studies, utility corridors and crossings and quantity calculations for dredging.

Precise & Higher Order Surveys

In 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.

Utility Corridor Surveys

Thompson Conn, in partnership with Eastcan Geomatics, has been providing topographic data for corridor profiles and cross section information to companies such as Nova Scotia Power, Maritimes and Northeast Pipeline, and Heritage Gas for many years in their development of power line and gas line corridors in Nova Scotia. This data has been collected using both conventional survey equipment and mapping from aerial photography and LiDAR sources.

Thompson Conn has also been recently involved with Newfoundland and Nova Scotia based survey companies to provide profile and boundary information to Emera Inc. for the development of a utility corridor for Newfoundland hydro development and distribution.
