3D Scanning in Construction (AEC)

1. Renovation As-Built Scanning
Most as-built drawings are inaccurate and incomplete as the data capturing is manual.
If a building renovation or retrofit is designed based on outdated or incomplete drawings, errors will be “designed in.” These errors will be completely invisible until the construction phase when they are very expensive and time consuming to resolve. The best way to avoid these unwanted surprises during construction is to perform 3D as-built scanning to capture the complete information about the space to be renovated.
Capturing accurate as-built data for renovations or retrofits requires first scanning all areas of the building involved in the project, then registering or stitching together the point cloud data. If drawings or models exist, the point cloud will need to be oriented to match the coordinate system of the drawing or model so both sets of data align.
From there, the as-built scan data can be compared to the existing drawings or models. The models and drawings can be adjusted to match the scan data so the team can begin design. If no models or drawings exist, the scan data can be utilized as a “template” to create the new documentation. The point cloud can be sliced horizontally to expose a plan view that can be traced to create very accurate floor plans, or it can be sliced vertically to expose elevation views for tracing. Isolating point cloud data is a great way to model or draft on point clouds.
2. Construction Validation
Construction costs and waste are at alarmingly high rates. The balance between speed and quality is difficult to achieve. Automated quality assurance tools provide valuable insights that help contractors plan better and head off problems before they materialize on the job site.
One of the simplest and most valuable laser scanning applications is scanning during the construction process to validate that the work put in place is as designed. Without the context of building elements yet to be installed, the naked eye cannot detect most construction issues. Laser scanning is the fastest and most accurate way to capture the complete Jobsite so work can be evaluated on a weekly or daily basis to assure the best quality construction.
This process starts with scanning all areas of the construction site to be analyzed. Then the point clouds are registered together and oriented to match the federated model. The point cloud data is then married with the model geometry and either visually analyzed or evaluated with automated tools to identify clashes and deviations (areas where model geometry exists but no point cloud data, or vice versa). When deviations or clashes are identified, the team can investigate the as-built point cloud and the virtual model to determine the source of the problem and find a resolution before it affects the schedule or budget.
3. 3D Laser Scanning in Topographical survey
A topographic survey is required to draw up a site map or a plan showing the natural features and man-made structures on a site. This type of survey is often also referred to as a land survey or a detail and contour survey. The final deliverable can be presented in a variety of formats from 2D plans and CAD files to 3D data with a digital terrain model (DTM) or even complete data-rich photorealistic point clouds.
A 3D Laser Scanning Survey Produces Faster Results, Cuts Field Time
In the past, field surveys could take days or even weeks to complete. Using laser scanning technology, it’s possible for us to complete the same field surveys in just one single day. Laser scanning also enables us to complete fly-throughs, 3D models, detailed animations, and maintenance materials in less time than ever before.
A 3D Laser Scanning Survey Reduces Overall Project Costs
The increased speed and accuracy of laser scanning means that our survey team has to complete fewer field visits to collect data. This reduces the overall cost of a project for you.
A 3D Laser Scanning Survey is a Highly Accurate
Laser scanning technology that produces the most accurate data available. This solid knowledge base helps us help you plan better projects.
A Laser Scanner Survey is a Versatile Tool
We use laser scanning technologies in many aspects of land surveying. We rely on laser scanning for budgetary and timeline preparation, application implementation, historical preservation, reaching once-impossible areas, change detection, hazard surveying, and accident reconstruction. We also use laser scanning to produce detailed topological maps, volumetric calculations, 2D drawings, 3D models, and more. Overall, laser scanning comforts us for improving actual building conditions, also laser scanning enables us to help our clients plan and execute the most efficient projects, and they allow customers to analyze every component of any facility or site. These capabilities help us make better decisions during every step of the project – from the planning stages through completion.
This multifaceted technology can be applied to a variety of land surveying needs, including change detection, accident reconstruction, 3D drawing creation, pre-project scanning, and more.

Manage Construction projects with Realtime data evaluation with 3D Laser scanning technology
1. Prevent Costly Mistakes
3D Lidar Scanning captures precise details about the environmental and physical site prior to and during construction. The high-resolution images captured by a 3D laser scanner are then turned into accurate 2D orthophotos and 3D models, creating a rich digital representation of your Jobsite. Then, data platforms like 3DR Site Scan make it easy to overlay design files onto 3d scanned data (point cloud data), enabling you to pinpoint constructability challenges in preconstruction, spot mistakes, and measure progress during construction.
2. Provide Better Project Updates
Owners and other stakeholders understandably demand progress updates on a regular basis. This can be a pain for you if you have to walk the site or send someone to take photos, and also some Real-time progress reports for the right construction without any further error or mistake. 3D laser scanning makes a comfortable way to decrease costly mistakes, provides better updates, improvise safety, and mitigate risks onsite. Stock Pile Volume Calculation
FIBROX3D provides highly accurate and fast volumetric surveys using laser scanning technology.
Measuring a stockpile volume using 3D Laser Scanner technology is by far the quickest and safest method available. Whether it's aggregate, coal, wood chips, asphalt, or anything else in your inventory, our lasers have the ability to measure to almost any surface without the need for a reflector.
Traditional methods require your crew to hold a prism pole and occupy areas of a large pile of material. This process can be time-consuming and sometimes dangerous. Some areas make using a total station and prism pole even impossible because of loose material that can cause safety hazards, not even mentioning the lack of detail and poor results you can obtain.
Sometimes, arranging for aerial fly-over is expensive and you will typically have to wait days or even weeks for the results. Depending on the time of year, the service may not even be available due to severe weather conditions. Times are tough so the need for monthly inventory assessments is becoming a reality. Time to complete measurement for each pile will vary according to the shape and profile. Generating the quantity from the software is very fast with the density available. Normally, we generate the provisional report for each day. Thus, you can expect to have the quantity on a daily basis.
