Back in 2015, engineers at MX3D made a huge announcement: they were going to 3D print a steel pedestrian bridge on-site. That plan has been altered slightly in the nearly 3 years since the announcement, but the group recently completed printing the full span of the bridge.
The ribbon cutting ceremony for the printers was held in late 2015 with a major change to the original design. Instead of printing on-site, the robots were now going to print the structure off-site, citing high traffic issues in the bridge’s final location. Although the ribbon cutting ceremony was held in 2015, the printing was not started until 2017.
It took 4 robots a total of 6 months to complete the 41 foot long, 20 foot wide span of the bridge. Nearly 10,000 pounds of steel was printed using roughly 683 miles of wire. When complete, the bridge will be installed in the Red Light District of Amsterdam over the Oudezijds Achterburgwal canal.
The next step for MX3D is to test the structural integrity of the bridge. As we’ve seen recently after the collapse in Florida, a pedestrian bridge collapse can have devastating consequences. To test the 3D printed bridge, a network of smart sensors has been installed on the structure, which allows the engineers to make a “digital twin” of the bridge. Gizmodo reported that, since this is the first 3D printed steel bridge that has existed, MX3D is working with the city to create a new safety standard for the category.
“Last Thursday we tested out the bridge with 30 people, and it was fine. It behaves like a bridge like it should,” MX3D co-founder Gijs van der Velden told Gizmodo in an interview. “With the bridge deck on top, it will be even stronger.”
The bridge is scheduled to be installed early next year. Check out the video below to see what it looks like...
What do you think of the design? Gizmodo thinks it looks like it broke off an alien mothership,” which is honestly pretty accurate.

CAT phones has made our headlines in recent years by matching their rugged design with a suite of features that no other phone can match, like the built-in thermal imaging, laser measure, and humidity and VOC sensors that the Cat S61 has. Those past phones have been unlocked and compatible with certain networks of the user’s choosing, but their latest release is starting out only available on the Sprint Network.
It’s been a long time coming, but the world’s first 3D printed steel bridge has passed all of its required testing and is ready to be installed. But, before it gets to its final home, it will go on a short publicity tour.
As was announced at PlanGrid’s first annual Construction Summit in June of this year, PlanGrid has officially released it’s new product “Tasks,” which will replace it’s other product “Issues” moving forward.
Tracking your construction project’s submittals and their approval status can be a tedious and frustrating process, but thankfully several project management applications are helping solve that issue with technology. At the beginning of this year, PlanGrid announced the release of an automatic submittal log creator tool, which scans through your project’s specification book and creates a trackable log of each submittal. The company has recently added several new features to make the Submittal platform, which allows users to manipulate the submittal log, even more useful.
I’ve mentioned this several times before, but the single greatest thing technology companies can do for the construction industry is to allow cross-platform integration. That’s essentially what construction is at its core, anyway, a bunch of different entities working together for a common goal. Autodesk’s BIM 360, which already integrates 60+ different softwares into its platform, has recently added NoteVault to its list.
When we’ve talked about construction robotics in the past, it’s mostly been about really large machines working on exterior structures, like this brick-laying robot, or this self-driving track loader. A technology institute in Japan is busy working towards bringing robotics to the interior finish side of the construction world with the development of a drywall installing robot.
PlanGrid users may have noticed, or been frustrated with that fact, that some features that are available on the program’s Android and iOS apps are not available on the Windows app. Windows’ Surface tablets have become a popular option for construction teams in recent years, so those users will be happy to hear that the Field Reports function is now available on PlanGrid for Windows.
One of the very first articles I wrote over 3 years ago was about SAM, the Semi-Automated Mason, which is a bricklaying robot. Since that time, SAM, which is made by Construction Robotics, has seen several jobsites, according to their portfolio page. Their most recent project at the University of Nevada has put the technology back in the headlines.
We’ve heard a lot of promising developments on construction technologies in the past few years, many of which will not only make the industry more efficient, but create a much higher quality product. Testing this technology inside of a controlled facility, however, doesn’t quite paint an entire picture for how the product will perform on a constantly evolving jobsite.
[sponsored] Construction daily reports are necessary for project management and tracking. The need to keep accurate and complete reports has caused the industry to evolve their process from pen and paper to spreadsheet software and now into simple to use mobile apps and software. This has greatly improved the way that daily reports are created, stored, and shared.
