3D Laser Scanning

Powers & Tiltman can provide you with 3D laser scanning and point cloud data sets using industry leading Leica Cyclone and Cloudworx software software.

Due to advances in technology, we can scan a site and collect a vast amount of spatial data at 1 million measured points per second, delivering it in HDR imaging up to a range of 270m. Our laser scanner picks up millions of points in any one area at speed giving a photographic quality to the plans which can be used for anything from panoramic walk-throughs to the final as-constructed layout of a building.

3D laser scanner data is processed in the industry’s leading 3D point cloud software suite, which consists of Leica Cyclone stand-alone software and Leica CloudWorx plug-in tools for CAD systems.

The benefits of 3D laser scanning surveys:

Accuracy

Our laser scanners pick up millions of geo-referenced points with millimetre accuracy, giving a precise and detailed picture of what is there.

Speed

With the ability to pick up one millions of points per second, the laser scanner can pick up vast swathes of land or buildings reducing the amount of time required on site and therefore reducing the total project life cycle and the cost to the client. In addition, Leica's 3D accuracy levels are cited as 3mm at 50m and 6mm at 100m.

Safety

Our laser scanners work remotely on site to capture difficult to reach areas thus removing the significant health and safety aspect that renders some projects unfeasible or less cost efficient.

3D Laser Scanning can be effectively utilised for a wide range of projects including:

  • 3D Building Models for integration into BIM software such as Revit
  • Archaeological sites and heritage surveys
  • Post construction scans for facility management
  • Topographical surveys
  • Civil infrastructure surveys
  • Detailed elevation surveys
  • Volumetric Surveys
  • Event Planning

It is possible to use 3D Laser Scanning before a project commences to assist with on-site logistics and allow designers to gain valuable data regarding information such as adjacent building heights or obtain vital dimensions for planning purposes.

Frequently Asked Questions

(1) Is laser scanning compatible with BIM?

Yes, all surveyed points using a laser scanner are 3 dimensional and are ideal for using with BIM.

(2) We have limited access time to carry out certain building surveys?

Laser scanning is ideal if access time is limited, as a vast amount of data can be gathered in a short space of time.

Point Cloud Scanned Surveys for BIM

As a result of growing demand in 3D point cloud models for integration into BIM software, Powers & Tiltman have invested in a Leica P40 ScanStation with Cyclone REGISTER and Cloudworx Pro AutoCAD software which delivers the highest quality 3D data and HDR imaging at a fast scan rate of 1 million points per second.

Whether you want to capture the 3D geometry of civil infrastructure, create an as-built representation of a large and complex building (inside or out), reconstruct a crime scene, create a heritage survey or generate 3D data for integration into Building Information Modelling (BIM), a scanned survey is the right choice delivering millions of detailed and accurate geo-referenced points.

Scanned surveys offered by this equipment are:

  • 3D Building Modelling Surveys (external elevations and internal layouts)
  • Scan 2 BIM – 3D models for integration into BIM software.
  • Heritage Surveys
  • Conservation Surveys
  • Structure Monitoring
  • Volumetric Surveys
  • Event Planning

Frequently Asked Questions about BIM

(1) How does a scanned point cloud survey differ from standard measured building surveys?

Measured building surveys are usually represented in a 2 dimensional setting such as a building elevation or a floor plan. Our point cloud surveys uses 3 accurate geo-referenced dimensions (width, height and depth).

(2) Why is BIM useful?

BIM can be utilised by many services at one time and as a platform this can be useful as it allows all parties to work together to establish highly accurate and standardised drawings that can be referred to at any time throughout the entirety of a project, from conception to completion.

(3) What is the role of a land surveyor within BIM?

Land surveyors create accurate 3D model drawings of buildings or landscape that can be integrated into BIM software such as Revit and AutoCAD Civil 3D. These can be scanned building facades or floor plans that can be produced in 3 dimensions.

(4) What is the extent of the Government Construction Strategy and its BIM requirements?

Since the introduction of the Government Construction Strategy (GCS) in 2011, all government departments met their target to procure all public assets using BIM level 2 by the end of 2016. GCS 2016-20 will focus on realising the full benefits of BIM level 2 by aligning the interests of those who design and construct a building with those who are ultimately the end users. GCS has tasked the BIM Working group to continue to develop further measures to derive more savings and efficiencies from BIM level 2.
