Survey controls provide points as foundations for building processes. A survey station is a location where observations are made. Once the site control points are established, other surveys can be completed, including topographical surveys, aerial mapping, as-built surveys, and more.

What is Site Control in Surveying?

Site control is surveying offers horizontal and vertical positions of points, that are used to adjust supplementary surveys. They set accurate benchmarks for subsidiary surveys to meet. Each project comprises of vertical and horizontal field surveys. These follow up surveys rely on positional control and accuracy.

This is used in project planning and construction, ensuring efficiency and accuracy. The skilled surveyors at MB Survey solutions, offer site control for surveying, using GPS receivers, levelling tools, and 3D laser scanners.

Site Control Types in Surveying

Control surveys create reference points and are essential in ensuring accuracy throughout your building project. There are five types of control surveys:

• First order surveys – accurate survey used for large projects. It connects a network of control points to provide precise referencing for the building project
• Second order surveys – these are used for medium sized projects that require less accuracy
• Third order surveys – used for small-scale projects that require less accuracy
• Geodetic surveys – precise earth curvature measurements set up control points
• Aerial surveys – aerial photographs and satellite imagery is used to set up control points

Why is Site Control Important in Surveying?

In the field of surveying, it is important to have a precise reference points for the location of the points on the surface of the earth. Most of the time we do this using horizontal and vertical points. These are set up using precise methods, such as trigonometry and differential levelling.

We set up control points to ensure all other surveying work are accurate, this includes carrying out measured building surveys, topographical surveys, and as-built surveys. With accurate site control, it is easier to find and measure points on the ground, it helps reduce inaccuracies.

Overall, site control is essential to our surveying process, helping ensure you receive accurate and reliable drawings you can use with confidence for your building project.

How MB Survey Solutions Do Site Control for Surveying

It all starts by looking at the area to see how well the fieldwork part of the project will work. We use site control to:

• determine accessibility of the project area
• Evaluate the current state of the project control
• Identify limitations of the environment

We then layer the station markets to evaluable the most suitable markers to use, assess the desired project points, and determine if the sky is visible in the project locations if GNSS is going to be used.

Conclusion

Site control is essential to any surveying process, helping us ensure accurate and precise measurements, along with determining what surveying techniques to use. We use this to determine the horizontal and vertical placement of points on the earth surface, creating a reference system to pinpoint other places on the surface.
