The Netherlands has a ton of bridges, especially pedestrian and biking bridges, thanks to its abundant system of canals. Perhaps because of that, they have become a leader in 3D printing technology when it comes to bridges.
A couple years ago, Amsterdam, the capital of the Netherlands, announced their intentions to print the first pedestrian bridge out of steel. That steel bridge has yet to finish and is hoping to be unveiled in June of 2018.
Most recently, a team of researchers from TU Eindhoven and construction group BAM infrastructure, joined forces to print a 26 foot long (8m) bicycle bridge in the Dutch province of Brabant. It took around 3 months for robots to print the concrete structures, which were placed in 800 layers, pre-stressed, and reinforced, according to dezeen.
The team is referring to the bridge as the "world's first 3D printed reinforced, pre-stressed concrete bridge". There was another bridge that opened in Spain in December of last year, which claims to be the first 3D printed bridge, but it's not clear if that was pre-stressed or not.
The concrete sections were printed offsite by the robots and later secured together, transported to the site, and installed under human power. Since using robots clearly doesn’t speed up the construction process yet, one benefit of printing the concrete is the ability to give it an extremely unique design, allowing less waste and making it more sustainable.
You can check out the 3D printing process in the video below, uploaded to Youtube by New Civil Engineer. Unfortunately, we English speakers will need to rely on the subtitles for the dialogue.

One of the key components of BIM is the ability to detect clashes, which are design coordination issues that result in the inability to construct a building as drawn. The use of 3-dimensional drawings allows contractors –and software- to detect if key building components are intersecting before it’s about to be installed in the field. Autodesk BIM 360 has recently updated its clash detection abilities within its Model Coordination module more easily and efficiently within its platform.
Hot off of the acquisition of Honest Buildings, a project management software aimed at owners and developers, Procore has announced they have acquired yet another tech company to help bolster their offerings.
Construction Management software company, Procore, initially launched their annual technology conference, Groundbreak, back in 2015. Originally hosted at their headquarters in California, the event has grown exponentially from that first year and this year may be its biggest yet.
In 2015, Milwaukee announced the release of their digital tool tracking platform: ONE-KEY. The company has since released dozens of ONE-KEY enabled tools to manage them using Bluetooth, an inventory management system, and tool reporting functionality. Yesterday, the company announced several enhancements to the platforms inventory and reporting interfaces.
In what can be expected to be a continuous trend in the construction industry, construction management software company, Procore, has acquired yet another construction tech company to further bolster their software.
3D printing technologies have significantly improved over the past few years and some have even made it to the jobsite. Not to be outdone, NASA, your favorite America space exploration organization, has announced a plan to being building and manufacturing in low-Earth orbit.
Construction Junkie's 5th Annual Best Construction Podcast Competition has officially come to an end and the results have been tallied. It was a very exciting competition this year, with several very strong competitors pulling in tons of votes.
Construction Junkie’s annual Best Construction Podcast Competition is underway for 2019 and the voting booth is officially open. As part of the contest this year, we will be highlighting one of the contest’s nominees each week. This week we highlight Builtcast.
Spot-r, made by Triax Technologies, is a hardware and software solution for employee tracking and safety. It combines a pager-style clip with a proprietary wireless mesh network to communicate hazards, evacuation notices, and locate who is on the site and where. The company recently announced the addition of access control to their Spot-r platform.
