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.

Execution Methodology

Organized steps for establishing an accurate, stable, and usable control network

01 Site & Project Requirements Review

The site conditions, project scope, surveying requirements, required control network type, accuracy level, coordinate system, and vertical datum are reviewed before fieldwork.

02 Control Point Location Selection

Control point locations are carefully selected to provide suitable project coverage while considering stability, accessibility, visibility, protection, and continued usability throughout the project.

03 Survey Observations & Measurements

Field observations are carried out using appropriate equipment and technologies such as GNSS / GPS, Total Stations, and Digital Levels according to the network requirements and required accuracy.

04 Data Processing & Network Verification

Survey observations are processed to determine coordinates and elevations, followed by the necessary checks and verification procedures to confirm network consistency and data quality.

05 Control Point Data Delivery

Coordinate and elevation schedules, control point data, and reference plans are prepared in the required format for use in surveying, setting-out, and construction works.

Survey Control Network Applications

A reliable surveying reference for different stages of project execution

Buildings & Structures

Providing accurate reference points for construction axes, setting-out, structure positioning, and verification.

Roads & Transportation

Establishing control points for surveying, design, setting-out, alignment, and elevation control.

Infrastructure

Supporting utility and infrastructure construction through a consistent surveying reference framework.

Industrial Projects

Establishing control networks for industrial facilities, large sites, and projects requiring precise survey control.

Topographic Surveys

Providing a consistent reference for topographic survey data, coordinates, and elevations throughout the site.

Setting-Out & Construction

Using control points as references for axes, coordinates, elevations, positioning, and construction verification.

Project Deliverables

Control network data prepared in formats suitable for project requirements

Survey Control Points

Established and monumented control points according to project requirements and intended use.

Coordinate Schedules

Organized horizontal coordinate data for the established control points and surveying activities.

Elevation Data

Elevations and vertical control data for reference points according to project requirements.

Control Network Plan

A reference plan showing control point locations and the information required for network use throughout the project.

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.
