Software Advances Push Point Cloud Use to New Level in Building Documentation

Users cite breakthroughs in registration speed, simplicity as key drivers. — Point clouds captured with professional-grade 3D laser scanners have long been the gold standard for as-built documentation because of their unrivaled accuracy and level of detail. More recently, innovations such as the imaging laser scanner have promised to make point clouds accessible to everyone. But achieving maximum usability of these rich 3D datasets has been impeded by a few hurdles. For one, registration of the point cloud – the process of aligning various views into a complete model – in the past required a certain level of expertise and manual manipulation. Loading and processing large point clouds could also be laborious and time-consuming, often adding hours or even days to the office side of the workflow. Fortunately, recent advances in software have eliminated these obstacles, paving the way for point clouds to become the universal foundation for building documentation. Continue reading…

How Backpack Mapping Transforms BIM Documentation

As every building construction professional knows, having accurate and timely documentation is key to ensuring that projects are completed on time and on budget. All too often, however, existing documentation is inaccurate, out of date or missing, and obtaining documentation during construction is time-consuming and complicated. This situation leads to guesswork and, ultimately, rework. Reality capture in the form of point clouds and imagery provides an attractive solution, but what’s the best way to capture reality indoors and out, as well as up and down stairs?

Video: Reality Capture for Pre-Design As-Builting

Starting with insufficient documentation on a renovation or retrofit project can lead to “designing in” invisible constructibility issues. Capturing digital as-built measurements before construction starts can completely eliminate these issues, thereby avoiding change orders, rework, and schedule delays. Watch the video to see how laser scanning reality capture provides a solution.

Video: Combining Layout And Flatness Scanning

Wouldn’t it be great if there was a way to perform flatness scanning on the fly during field layout? A scanning total station makes it possible. Watch the video to see how advanced hardware and software add intelligence to construction for more accurate layout, faster flatness analysis and improved elevation mapping.

Field Layout Masters: How Successful Construction Firms Get It Right

Low productivity and high waste are common problems in building construction, driven largely by unexpected rework and change orders. Additionally, the complexity of buildings has increased, along with owner expectations to lower costs, accelerate turnaround and increase quality. Still, some construction firms have found a way to thrive in this environment. Their secret? The adoption of new processes, such as building information modeling (BIM) and digital workflows. The recent collaboration between Autodesk and Leica Geosystems is making cloud-connected, model-driven field layout even easier so construction teams can increase jobsite productivity. In a 60-minute webinar on September 3, Leica Geosystems’ Cathi Hayes and Autodesk’s Zach Crumal showed how the alliance between the two technology giants can improve your layout process. You can now view the webinar on-demand.

Accurate by Design: How Reality Capture Transforms Construction

The use of laser scanning in construction is soaring—and for good reason. On a typical construction project, rework accounts for 12 to 15 percent of the cost of construction. With laser scanning, the ability to catch conflicts before they happen can reduce rework to 1 to 3 percent or less. This reduction translates into hundreds of thousands of dollars in savings on change orders, not to mention the advantage of keeping the project on schedule. The new collaboration between Autodesk and Leica Geosystems is making the adoption of laser scanning even easier for construction teams. In a 60-minute webinar on September 1, Leica Geosystems’ Cathi Hayes and Autodesk’s Eric Richie went behind the scenes on the alliance between the two technology giants to share cutting-edge success strategies.

Technology Plus Training Is Key to BIM Success

The benefits of using BIM for MEP layout are overwhelmingly positive. However, adopting this new process is not without a learning curve. For seasoned foremen like Tom Brown, a leading foreman’s instructor with Nelson-Carlson, learning a new technology and adopting BIM takes some getting used to. “Many mechanical and plumbing shops are in a constant struggle to turn a profit. Contractors need to start making money immediately following their BIM investment, which can be a tall order without the right training,” he says. Continue reading…
