Survey Control
A reliable foundation for every measurement
Survey control
A reliable foundation for every measurement
Accurate survey control is the foundation of every successful construction and engineering project. If control is wrong or inconsistent, every level and position set out from it is too.
JG Engineering designs, installs and maintains robust site control networks. They give one reliable reference for surveying, setting out, machine control and construction. Using high-precision GNSS and total station, we install control points, either permanent stations or survey nails, where they will last through the project. We then observe and adjust them with closed traverses, precise levelling and least-squares checks. Control is tied to Ordnance Survey National Grid and Ordnance Datum Newlyn through OS Net. Where needed, we also provide a site grid with clearly documented transformation parameters.
Control reports
Everyone working to the same reference
Every network comes with a clear control report and station coordinates. Engineers, contractors, subcontractors and machine-control systems can then all work to the same reference with confidence.
Whether we’re establishing control at the start of a project or extending, checking and re-establishing an existing network as the site develops, our approach focuses on accuracy and consistency. That ensures reliable setting out and dimensional control from groundworks to completion.

FAQs
Survey control questions
Survey control is a network of accurately coordinated reference points on and around a site. Every survey, setting out and machine control position is measured from it, so it needs to be right and to last through the project.

Yes. We establish control at the start of projects and also extend, check and re-establish existing networks as sites develop.
A clear control report with station coordinates, so engineers, contractors, subcontractors and machine-control systems all work to the same reference.
