A Better Way to Use Point Clouds in AEC Projects

Laser scanning helps lower building contractor risks by ensuring as-built drawings are accurate and by exposing any inaccuracies early in the process, before they turn into change orders during construction. One area where contractors increasingly want to use point clouds is in the QC/QA process. Scanning the real-world construction site and comparing the point cloud data with the models can help identify potential problems and clashes before they occur. However, most commonly used modeling software was not designed to manage and manipulate point cloud data, making it difficult to leverage the power of rich, high-accuracy 3D point cloud data sets for project review and analysis. A recent development provides a solution. Continue reading…

How to Clash Scan Data

Autodesk Navisworks was mentioned in a previous post as our primary clash detection tool. Aside from simply bringing in the point cloud and visually confirming the models match, we can also use the Clash Detective window within Navisworks to coordinate what’s been built versus what’s about to be installed with significantly more intelligence than a walk-through of the model.

Using Point Clouds in Clash Detection

We use Autodesk Navisworks almost exclusively as our primary clash detection tool. However, up until about a year ago, we have only worked with “projected” models – that is, shop drawings in 3D format that convey what the project will look like once that particular system is installed. Combining all of these files into Navisworks usually results in what’s known as “clashes,” or conflicts between systems where certain elements are competing for the same space. Continue reading…

An Essential Tool for a Standout BIM

High Definition Surveying (HDS) is not a new technology. It has long been applied in many other industries for applications such as crime scene investigation, car crash analysis, historical documentation and clash detection. However, it has recently begun taking off in the AEC industry, and we’re seeing a lot more activity from almost all stakeholders, including civil engineers and architects. Continue reading…

A Leading EPC’s Experience Using HDS Services on Multiple Projects

Leading EPCs experience

One of the first presentations I attended at HxGN LIVE 2013 was from Tellepsen – a Houston-based contractor that’s partnered with a local scanning company called Truth. They shared lots of great examples, but the one that hit home was their use of point clouds and Navisworks. Continue reading…
