Establishing Reliable Survey Control for Construction

Talk to us about your asset

Survey control provides the spatial reference that connects design information with measurements taken on site.

RM Surveys establishes and maintains construction survey control networks suited to the requirements of civil, commercial and infrastructure projects. Our surveyors assess site conditions, project tolerances, design information and construction sequencing to determine appropriate control arrangements.

From initial site establishment to ongoing verification, we provide survey control points and reference information that support construction set-out, machine control and measurements across different work areas.

Working closely with builders, engineers and subcontractors, we help maintain a consistent surveying framework as projects progress and site conditions change.

Consistent Survey Information Across your Site

Survey control underpins the accuracy of subsequent construction measurements. If control points are disturbed, inconsistent or incorrectly referenced, errors can carry through multiple stages of construction.

Our surveyors establish suitable control networks, document reference information and undertake checks as required throughout the project.

We also coordinate control requirements with construction teams, helping ensure different trades and survey activities are working from compatible spatial references.

This provides greater confidence in set-out, verification and construction data, while reducing the risk of avoidable discrepancies between work areas.

Frequently Asked Questions

What is survey control in construction?

Survey control is a network of established reference points used to determine positions, levels and alignments consistently across a construction site. It provides the basis for construction set-out and verification.

When should survey control be established?

Ideally, survey control is established before major site works commence. Early planning helps align the control network with design information, site access and construction requirements.

Does survey control need to be checked during construction?

Yes. Control points can be affected by excavation, machinery, temporary works and changes to site conditions. Periodic verification helps maintain confidence in the network.

Can the same survey control be used by different contractors?

Yes, where suitable for their work. Clear documentation and coordination help surveyors, subcontractors and machine-control teams use a consistent reference system.
