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.

Bluebeam Revu is a very popular PDF markup and collaboration tool for the construction industry. Each year, the technology company updates its flagship program to adapt to how their customers currently use the program and makes changes to increase their productivity. Bluebeam recently announced the launch of Revu 2018 and we have a breakdown of all of the changes.
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.
[guest post] The “fatal four” are falls, electrocutions, struck by an object, and caught in/between. Falls alone cause over half of the deaths in construction. With today’s technology, the fatal four could be a thing of the past.
Once upon a time, Dropbox was a place to store your files on the cloud. Now, users are demanding much more collaboration with their files and their teams, so Dropbox has been evolving to meet those needs. Much like other technology companies in Silicon Valley, Dropbox has taken note of the opportunity for growth that the construction industry offers due to general unwillingness to adopt new technologies in the past. The company recently announced that they are forming partnerships with several construction technology companies like PlanGrid and Aconex.

The construction industry uses too much paper. Ignoring any environmental impacts that may cause, the continued widespread use of paper in the industry is terrible for productivity and efficiency. Construction companies are burdening their employees with tedious paperwork instead of allowing them to excel at their actual jobs. It also greatly hampers collaboration with other team members or customers.
As the construction industry moves further away from handshake deals and getting work solely based on relationships, the importance of marketing your construction company outside your core customers is becoming more and more important. While many companies still don’t have a website, most have at least some sort of online presence.
Over the years, the World of Concrete has become one of the premier construction events across the country. The name may make you think it’s strictly related to concrete, but the truth is that anyone in the industry can find value in attending the massive event. Each year, the Most Innovative Products featured at the World of Concrete are chosen and Hanley Wood, a construction information and marketing company, recently announced the winners.
Caterpillar, a company known for their rugged heavy construction equipment, made headlines in the construction technology world in 2016 when they released the first ever smartphone with a built-in thermal imaging camera, the CAT S60. The company announced on Thursday that its ultra-rugged flagship smartphone would be getting an upgrade with the upcoming release of the new CAT S61.
