3D Laser Scanning Survey – An Overview Of The Technology

3D laser scanning survey equipment, also known as light detection and ranging (LIDAR), is a highly effective form of technology for collecting survey data. A 3D laser scanner can make multiple measurements in quick succession and then produces geometrically accurate data, known as a point cloud, by reflecting laser beam signals from a surface or object. By utilising the latest laser scanning technologies, a surveyor can capture very dense point clouds comprising of millions of connected points in mere minutes. This rapid form of survey measurement ensures minimal disruption and it also eliminates the need for multiple site visits, for your safety and convenience. This point cloud, typically composed of a huge number of data points to form an image, can then be used for a variety of different purposes, including for example the creation of 3D CAD (computer-aided design) models of manufactured parts and products, or for BIM Modelling Services, and so on.

How A Building Surveyor Uses 3D Laser Scanning Surveys in Construction

The use of scanning techniques by laser for surveying is now widespread throughout the construction industry. Previously, measured surveys were performed with handheld tools, perhaps in later years with the addition of a computerised Electronic Distance Measurement (EDM) devices. However, laser scanning offers a surveyor the opportunity to take far more precise measurements faster, and in an increasingly wide variety of circumstances and situations too. This includes the ability to reach previously inaccessible areas, from tight corners to high altitudes; and to map in a far more sophisticated way the intricacies of a complex structure. In terms of existing or planned assets in the construction industry, a 3D laser scanning survey assists with Building Information Modelling. This is the creation, collection, and management of digital information about any built asset, from a building to a tunnel, a motorway or a bridge, for example. This data can then be used at every stage of the built asset’s existence, from planning to construction to ongoing management throughout its lifecycle. But what is the data gathered by laser scanning in construction used for? In short, it’s about making better decisions at all stages of a built asset’s lifecycle. These decisions improve the cost-efficiency of the construction process and the ongoing management of the built asset once it is in operation. The data can also be used in the early stages to improve the functionality and performance of the built asset.

How Do The Benefits Of A 3D Building Survey Add Up For General Contractors?

There’s no doubt that incorporating a 3D building survey into plans for the refurbishment, reconstruction, or new construction of a property or building asset adds to the efficiency of the overall project at the outset. It’s a significantly faster method of measuring and recording data about an existing asset that new designs can be based on. What might typically take days or even weeks to achieve with older methods can be completed in a day or so, on average. Next, it’s worth bearing in mind that on any typical construction project, between 12% and 15% of the project budget is spent on undoing and redoing work that then turns out to be inaccurate or not fit for purpose. Because of the high degree of accuracy with which measurements are taken, a laser 3D site survey is capable of drastically reducing errors in construction by identifying risks in advance. This is not only estimated to save up to 12% of costs usually spent on after-the-fact fixes, but also helps keep the project on track for completion according to the scheduled timeframe. Additionally, laser survey data can be used to calculate the amount or volume of materials needed to complete work in particular areas – how much concrete is needed for a floor, for instance. This in itself can result in savings on over-ordering of materials. And once the survey is complete, the data can be used on an ongoing basis as the project progresses, comparing the actual construction with the original designs, in order to measure and demonstrate quality assurance.

Deciding on The Capabilities Required of a 3D Laser Survey when Hiring Expertise

The results of a 3D laser scanning survey can have a variety of applications across the construction industry. Before hiring in expertise, it’s well worth analysing your requirements and discussing these with individual service providers to ensure you will be receiving data you can use and are not paying for more than is necessary. In its simplest form, 3D laser survey data can be utilised to evaluate the progress of construction against the original plans and design for the asset. Using BIM or CAD software, scanned data can be compared against design measurements to flag up any potential problems. Revised measurements can then be incorporated by the designers to avoid the time and money costs of having to rectify issues at a later date. In more complex scenarios, the survey data can help build up a picture, and then a resulting model, of either part of or of an entire building due for refurbishment where previous documentation is incomplete or missing. The new building information modelling data then provides a platform from which additions or renovations to the existing structure can be designed on an informed basis, thus preventing costly errors during construction.
