Laser scanning has many advantages for highway surveys and Scantech has undertaken many such surveys including
There are clear reasons why this technology should be considered in both tender and detailed design stages and there are also many benefits :
- Roundabout schemes
- Conversion for Cycle routes
- Bus Lanes
- Metro Routes
For certain areas of a more complex nature such as interchanges and roundabouts where 5mm accuracy is required, we generally utilise static scanning from a position of safety on the pavement or verge. This eliminates the need for road closures and the associated cost and eliminates the risks in working on the road even with sections coned off.
BIM Models for Highways
By utilising laser scanning allied to traditional surveying we can capture a large amount of data in a relatively short time. The new SX10 laser scanner reduces the time to produce the 3D model even more as it coordinates each scan position to the control as it combines a 1 second EDM with the laser scanner in one “box” so to speak. While scanning the surveyor can also capture features such as manholes using the GPS which gives a tertiary check on the accuracy of the registration process.
The advantages of using laser scanning are :
- Work from position of safety on the pavement
- Avoids road closures
- Captures surrounding features such as houses/buildings walls etc
- Fast capture of accurate data
Why Scantech ?
We have over 15 years experience of using laser scanning allied to traditional surveying as we were one of the first five companies in the UK to purchase a laser scanner. Consequently we can produce accurate 3D models from the pointcloud data in a variety of formats and our engineering background allows us to understand the requirements of design in a civil environment.
