Laser Scanning
A fundamental starting point to any project
Laser Scanning Surveys
3D Laser scanning has become widely accepted and invaluable technology when capturing data of the built environment be that buildings interiors and facades, infrastructure, building services and much more.
Laser scanning technology is becoming increasingly important for construction project planning and execution because it produces detailed 3D models that can be used to analyse conditions and provide accurate designs.
Several of the industries in which we work necessitate extensive surveys with a high level of accuracy and detail. Manufacturing plants, commercial construction, historic structures, infrastructure construction and maintenance, and other assets with complex geometry all rely on laser scanning's detail.
A well-planned and executed laser scanning survey is frequently the first step in digitising an asset, allowing our clients to manage their portfolios using BIM and other digital technologies.
A large amount of detail can be captured accurately and efficiently in a short period of time. Creating high density coloured point cloud data, which can then be transformed into a variety of deliverables ranging from traditional CAD deliverables to 3D models like BIM, depending on the client's needs.
As the full original data sets are available to refer to, rather than just the linework that was traditionally surveyed, it helps to avoid assumptions and errors in understanding.
Capturing the data
3D Laser scanning is process of projecting a reflectorless laser line over a surface in order to gather 3-dimensional data known as 3D laser scanning, sometimes known as LIDAR (Light Detection and Ranging). The laser scanner's camera sensor, which records precise, dense 3D points in space, collects the surface data. Laser technology used, the scanner can operate in dim light without compromising the accuracy of the survey.
A point cloud representing the studied surface is created from the combined 3D survey points
Point clouds can be viewed in true colour from a digital camera or multi-hued colours (depending on signal strength return). This method offers a way to quickly survey difficult-to-reach surfaces or intricate building elements. The information can be smoothly matched with topographical survey plans, elevations, and sections. It can also be linked in 3D to site grid.
Benefits of Scanning
Working with laser scanning data has several advantages that give multi-disciplinary teams an edge, including architects, building services, civil engineers, and space planners to name just a few. By having the original data set available for reference, laser scanning helps prevent assumptions, generalisations, interpreting errors, and issues.
Some of the benefits 3D Laser scanning
- Minimises fieldwork time avoiding the need for revisits
- Records visible features that are inaccessible physically, such as a coastal features, a preserved façade, ceiling details then laser scanning is an ideal solutions
- Ideal when access time is limited, such as highways, bridges, leisure facilities, building internals
- Can be used in low light or where only night work is permitted.
- Captures intricate detail, such as historic buildings with elaborate features or complex steel details
- Creates a permanent, always-accessible record of the site at a particular point in time, even though it might not actually be there anymore.
- Modifying project' scopes without having to go back to the site
- Producing 3D models for BIM applications it is ideal
- Clash detecion
By utilising and embracing technologies such as 3D Laser scanning over traditional methods for data capture we have noticed a time saving both in the field and digitising the data of 50-80%
Thus, delivering the best balance for your projects
Deliverables
Deliverables from laser scanning can be as simple or as complex depending on individual project requirements
Basic raw point cloud data from the scans can be delivered to a clients' team to allow them either work on the data themselves or archive it for historical purposes or we can transform the data in to full 3D models, wireframe drawings or immersive fly throughs
Some of the deliverables from 3D laser Scanning are;
- 2D & 3D plan drawings both in digital and hard copy presented in predefined scales in accordance with RICS guidance
- Point Clouds supplied in E57, PTX, PTS, LAS, LAZ, Recap (RCP, RCS) formats
- Elevations, profiles and sections
- Panoramic images with interactive measurements from each pixel
- 3D Models
- 3D Visualisation
- 3D Animation/Fly-Through Video
- Building Information Modelling (BIM)
Added Value
3D Laser scanning point cloud data can be further augmented with the addition of an underground utility survey thus given a client and their team a complete and accurate picture of above and below ground.
Our collaborative, multi-disciplinary, single supplier approach to geospatial surveying solutions brings confidence and repeatability to our clients ensuring they have one point of contact and source for their project with a unified process and workflows, ensuring repeatable and reliable quality assurances by utilising the latest technologies combined with experienced people to delivery high quality reliable deliverables for clients and their complete projects

Like to know more - CPD Events
We appreciate that all the different technologies and terminology is second nature us but to you our clients it may very well be confusing and daunting.
OmniSurveys offer educational "Lunch & Learn" one hour Continuing Professional Development (CPD) educational events to our clients
Our aim with these events to educate and keep our clients staff updated not only on specification changes but with the rapid developments within the geospatial world both in surveying technologies, data capture methods, workflows but how these can enhance quality of deliverables, time and costs.
At these events we explore the Geospatial surveying solutions we offer to give our clients and their staff a better understanding of the different types surveys we offer along with the technologies we use.
This can include:
- Topographical Surveys
- PAS128 - Underground Utility Mapping
- Measured Building Surveys
- Engineering Surveys
- Laser Scanning
- 3D Modelling & BIM Surveys
- UAV Drone Surveys
Having carried out many of these events over the years we have found our clients and their teams have taken a lot away from them and thus resulted in better collaboration providing clients with more tailored surveys with better value through better knowledge.
Tailored events can be arranged on specific topics of interest such as PAS128 Utility Mapping, UAV Surveys, Laser Scanning & Modelling
