Control Network Installation Surveys for site investigation
Control network installation surveys are a critical component of site investigations.
About
What are Control Network Installation Surveys in Site Investigation?
These surveys provide a precise and stable framework for all subsequent surveys and construction activities by establishing a reliable network of control points across a project site.
Control points, often physical marked with stakes or flags, serve as reference markers that are used to ensure the accuracy of all survey measurements across a site. The accuracy of these control networks is vital as they directly affect the quality of data gathered for topographical, boundary, and geotechnical surveys, among others.
In the context of site investigation, control network installation surveys are performed early in the project lifecycle to provide a solid foundation for mapping, design, and construction planning.
By ensuring all future measurements are consistent with the control network, these surveys help avoid discrepancies, alignment issues, and costly errors that could arise during construction.
Whether it’s for a large infrastructure project or a smaller residential development, establishing a robust control network is essential to achieving accurate and reliable site data.

Lifecycle
How are Control Network Installation Surveys Designed, Planned, and Carried Out?
Control network installation surveys follow a structured and methodical approach to ensure accuracy and reliability. Here’s a breakdown of how these surveys are typically designed, planned, and executed:
- Initial Consultation & Site Assessment
The process begins with a thorough understanding of the project’s scope and requirements. During this stage, Igne’s survey team consults with project managers, engineers, and other stakeholders to identify the most appropriate locations for control points. Factors such as site size, terrain, existing infrastructure, and potential obstructions are considered. - Network Design
Once the site is assessed, a detailed plan is drawn up for the control network. The design specifies the number and location of control points needed to cover the entire project area. In most cases, primary control points will be established in stable, permanent locations, with secondary control points added as needed to fill in gaps or provide additional reference markers for more complex surveys. - Installation of Control Points
The installation phase involves physically marking the control points on-site. These are typically small, permanent markers such as metal stakes or concrete monuments, depending on site conditions and the expected duration of the project. Igne uses high-precision GNSS equipment and total stations to ensure that each control point is installed in exactly the right location. - Surveying & Data Verification
After installation, the control points are surveyed to verify their exact coordinates, which are then recorded in the project’s digital mapping system. Redundant measurements are often taken to ensure accuracy and minimise any errors due to equipment limitations or environmental factors. The data is then reviewed and validated by Igne’s survey team before being shared with the client. - Ongoing Monitoring & Maintenance
For long-term projects, control networks may require periodic monitoring to ensure the markers have not shifted due to environmental changes or construction activity. Igne offers ongoing support and maintenance services to ensure that the integrity of the control network is maintained throughout the life of the project.
Benefits
What are the Benefits of Control Network Installation Surveys?
The benefits of commissioning a control network installation survey are multifaceted and extend well beyond the initial stages of site investigation:
Improved Accuracy
By establishing a precise control network, all subsequent surveys and construction activities can be aligned with a common reference, ensuring consistency and reducing errors across the project.
Compliance with Industry Standards
Control networks help ensure that all site data complies with relevant industry standards and regulations, providing peace of mind for clients and project stakeholders.
Risk Mitigation
A robust control network reduces the risk of unforeseen issues that could disrupt the project, such as boundary disputes, inaccurate site plans, or alignment problems during construction.
Time & Cost Savings
With a reliable control network in place, surveys can be conducted more efficiently, reducing the need for repeated measurements or costly adjustments later in the project. Accurate data from the outset minimises the risk of costly mistakes during construction.
Enhanced Collaboration
Having a well-documented control network allows for seamless communication and collaboration between different project teams, from engineers and architects to contractors and developers. Everyone can work from the same data, reducing the likelihood of miscommunication or data discrepancies.

Frequently Asked Questions about Control Network Installation Surveys
- What is a control network installation survey?
A control network installation survey establishes a grid of reference points across a site that serves as the foundation for all subsequent surveys and construction activities. These control points ensure that all site measurements are accurate and consistent.
- Why is a control network important for construction projects?
A control network provides the framework for precise measurements throughout a construction project. Without it, there could be discrepancies between surveys, leading to alignment issues, errors, and potentially costly delays or mistakes.
- How is a control network maintained?
For long-term projects, it is essential to regularly monitor control points to ensure they have not shifted. Environmental changes, construction activity, and even natural wear and tear can affect the stability of control points. Igne offers monitoring and maintenance services to ensure the ongoing accuracy of your control network.
- How accurate are control network installation surveys?
The accuracy of a control network installation survey depends on the equipment used and the conditions of the site. Igne uses advanced surveying equipment like GNSS and total stations to achieve high levels of accuracy, often within millimetres.
- Can control network surveys be conducted on any type of site?
Yes, control network surveys can be conducted on various types of sites, including complex environments like brownfield sites, urban areas, and large infrastructure developments.
