3D Laser Scanning

3D Laser Scanning is a non-contact, non-destructive technology that digitally captures the shape of physical objects using a line of laser light. It’s a cost-effective way to capture the exact size, shape and location of objects underground without unnecessary site disruption. Laser scanning survey teams at Subscan UDS produce three-dimensional building and structure models that deliver previously unimaginable levels of information, detail and accuracy.

At Subscan we have a dedicated team of inhouse specialists who complete comprehensive site surveys with speed and accuracy across the UK. Subscan UDS use the latest detection techniques including 3D Laser scanning to locate utilities, ensuring workers know exactly what buried obstacles they may face before coming across them, minimising costly delays from unknown obstacles.

  • Topographical, measured building and as-built surveys
  • Surveys of limited access or hazardous areas
  • Volume surveys and engineering calculation
  • Virtual reality models, site visualisations, 3D walk-through models and more
  • Structural and land deformation monitoring
  • Mobile 3D Laser Scanning

Preparation is key

It’s a legal requirement that before digging you should be aware of what is beneath the surface, ensuring there are no hidden surprises when you break ground. A hit gas main can not only be costly in terms of time and money, it can cause injury or worse.

The data 3D Laser scanning is highly detailed and helps complex decision making.

Why Subscan?

3D Laser Scanning is fast becoming the industry norm for precision surveying in high precision and high value technical environments. As one of the first companies to adopt Laser Scanning technology, Subscan are one of the most experienced drainage specialists in the UK.

Each survey Subscan completes is presented in layered CAD models with an accompanying report ensuring you have all the information required to make informed, and safe, decisions on site.

Case Study

Client:
Highways England

Project type:
Topographical and Underground Utilities Surveys

Location:
North England

Overview

Subscan undertook 3D Topographical and Underground Utilities Surveys in the central reservation along a 4km stretch of highway, along with the excavation of 16 trial trenches to verify the Underground Utilities.

Subscan were appointed to undertake 3D Topographical and Underground Utilities Surveys in the central reservation along a 4km stretch of A66. The Project also included excavations of 16 trial trenches to verify the Underground Utilities identified within the survey as part of the barrier replacement scheme.

As part of the project Subscan deployed 3 teams of 2 surveyors to complete the full works required by the project, within 10 working days of site work. Underground Utility Surveyors located numerous services located along the survey area and were able to trace all of them with great precision.

Topographical surveyors established a rigid control network prior to carrying out a full 3D survey of the area as well as mapping all the Utilities found by the Underground utility Surveyors.

Trial trench excavation teams were able to expose the services found by the Underground Utility Surveyors within the trial trenches, which then verified the accuracy of the survey to the client.

Lead Surveyors produced detailed drawings and reports which were delivered to the client within the time allocated.

Client Testimonial

“The Subscan UDS team of surveyors and drainage engineers helped our minor works team out again and did a thoroughly professional job. We will continue to work with Subscan on LNE projects throughout the region.”
