3D Scanning

CEDR uses a 3D laser scanner as the ultimate mapping tool in the industry, since it is a safe and time efficient, as well as a reliable and high accurate device. CEDR has realised 3D-related projects in industries such as the chemical industry, food & beverage manufacturing, the recycling industry, material handling, tank storage, etc. Through scanning in different conditions, on different terrains, and with different requirements, CEDR already has several years of specialist expertise regarding 3D modelling. Customised and personal interaction with our clients, adds for this to be the most complete way to determine the dimensions for as built and concept phase scenarios, and everything in between.

The 3D laser scanner collects data from a safe distance and has the option to be remotely operated in less than optimal or even hazardous conditions. This data eventually replaces any need for close-up (daily) interventions and therefore reduces the physical hazard risk to a minimum for people on site. Also, excess field time is eliminated because all data is collected by one person at once. Three-dimensional laser scanning prevents complex and time-consuming conventional mapping. It translates into a cost-effective advantage since safety equipment, like safety harnesses and scaffolding, are no longer necessary to perform measurements on site. Field measurements are substituted and done back office, using the provided data from CEDR. Processed scan data can ultimately be converted into a 3D model, which allows for clients, project managers, and anyone involved to get a real-world view of the site and project area without physically needing to visit the site. There is always and everywhere fast access to the reliable digital data. Numerous benefits follow from this. Engineering plans can be connected to as-built situations. Deliverables with the highest accuracy are created. Guesswork and human errors are taken out of the equation. It allows engineers to avoid conflicts that in the past would not have been noticed until the construction phase.

3D laser scanning is a non-destructive technology which digitally captures and registers a three-dimensional view of the surroundings, at high speed and with precise accuracy. A digital HDR camera completes the 3D scan with 360-degree detailed imagery and a natural colour overlay. The scan result is independent of external light intensity (e.g., direct sunlight). An integrated GPS can be activated, which enables easy positioning and subsequently easier processing of the data. Given that a 3D laser scanner records up to one million points per second, the scan eye extends up to a height of 5 meters, a distance range from 0,6 to 150 meters is possible, and the scan accuracy reaches down to 1 mm, all contribute as key features of this state-of-the-art technology.

After the project scope is determined and the scan area is defined, the scanning process can commence. Scan locations are strategically placed around the asset to produce the best quality result. 3D laser scanning is an advanced method to capture the finest details of any physical object’s surface, such as exact size and shape. Once completed, the registered scan data is connected through software to create point clouds. A point cloud is a digital three-dimensional representation of the scanned area/ objects and provides the necessary data to start the 3D modelling.

The 3D scanning device cannot measure through objects; it detects what one would see with the human eye.

A point cloud cannot directly be converted into a 3D CAD drawing. Nonetheless, it can be used as ‘layer’ for the CEDR 3D drawing design work.

CEDR can use this technique also for inspection purposes. The scanned object can be compared to the designer’s CAD data. The result of this comparison process is delivered in the form of a “colour map deviation report,” in PDF format, which pictorially describes the differences between the scan data and the CAD data.

In addition to a 3D laser scan, we have engineering input available from disciplines such as process & project, mechanical, E&I, and civil. CEDR also offers HAZOP support if needed.

Besides point cloud clash detection and process optimalisation, the following deliverables can be created based on the data from the scans:

2D designs & 3D models

CAD drafting services

Technical drawings

BIM Modelling

To summarize the advantages of 3D laser scanning by CEDR:

One-time scanning (of hard-to-reach places) offers long-term digital accessibility

Verification (real time) of existing structure with no physical inconveniences

Clear 3D view of complete (project) site can be used for multiple applications

Drastically decrease reading and measurement errors, avoid speculation

Perfect layer for the 3D modelling drawing work

Simultaneously fast and detailed data recordings of the specified project area

No turning back to the plant/production site for ‘forgotten’ measurements

Eliminates the cost of safety equipment and scaffolding during measurements

More time efficient than conventional mapping

Control measurement, as built documentation

3D views are the better alternative to an excess of photos, comments, and old drawings

Not everything which is scanned needs to be drawn at once

Easy measurement for complex structures

Ideal for visualization and simulation

Engineering & construction of new and/ or adjustments to existing infrastructure, based on the 3D design

Save time. Reduce Costs. Gain higher efficiency. Get better results!
