Survey Control Networks & Control Points
Establishment and monumentation of accurate horizontal and vertical survey control networks and reference points, providing a reliable surveying framework for topographic, design, construction, and setting-out works.
A Reliable Surveying Foundation
Establishing a consistent reference framework for surveying and engineering works
Survey control networks provide the reference framework required for surveying, construction, and setting-out activities. They consist of accurately established points with known coordinates and elevations that can be used throughout the different stages of a project.
Total Surveying Office provides horizontal and vertical control network establishment and survey control point services according to site conditions, project size, required accuracy, and the approved coordinate and elevation reference systems.
Control surveys are performed using appropriate surveying technologies and equipment, including GNSS / GPS, Total Stations, and Digital Levels, together with the necessary field observations and checks to verify point accuracy and network consistency.
Established control points can serve as the reference for topographic surveys, construction setting-out, axis and structure positioning, construction monitoring, and integration of surveying data within a consistent coordinate and vertical reference framework.
Survey Control Network Scope
Accurate reference points supporting a wide range of surveying and engineering activities
Horizontal Control Points
Establishment and monumentation of horizontal control points with known coordinates for surveying, setting-out, positioning, and site control activities.
Vertical Control Points
Establishment of elevation reference points and connection to the approved vertical datum to support leveling, elevation transfer, and construction control.
Point Monumentation & Protection
Selection and stabilization of suitable control point locations while considering accessibility, stability, visibility, and long-term usability.
Coordinate System Connection
Connecting the control network to the project's approved coordinate and elevation reference systems and preparing the required surveying reference data.

A Precise Reference for Project Works
A properly established survey control network provides a consistent coordinate and elevation reference across the project, helping reduce discrepancies between surveying, design, and construction activities and providing reliable points for setting-out, verification, and control.
Control points also allow different surveying activities to be integrated within a single reference framework, whether for construction, industrial, roads and infrastructure, or large-scale topographic projects.
