3D printing technology faces major issues when it is required to leave the shelter of a warehouse and step foot on a construction job site. 3D printers are extremely large, heavy, and rely on precise calibration for accuracy. Even the first 3D printed office building in Dubai, which was completed last year, had to actually have its components printed off site and assembled on site. But, Apis Cor, a 3D printing company, believes it has created the technology to print a full structure completely on site.
In the video below, you’ll see footage of a 409 square foot (38m²) concrete house being printed in Moscow, Russia in December of 2016. According to the company, the machine they used has a maximum elevation of nearly 11 feet (3300mm) and can print up to 1,076 square feet (100 m²) per day. The machine also has a built-in automatic horizon alignment and stabilization system, which makes setting up the printer much easier.
Although the machine is able to operate in temperatures as low as -31°F (-35°C), the material used, which is a concrete mixture, is only able to be placed at temperatures higher than 41°F (5°C). Therefore, a tenting system had to be brought on site to raise the temperature inside.
The total cost of the building amounted to $10,134, which included all exterior and interior finish work. Noticeably missing from the cost breakdown on the company’s website was the price of the 3D printing technology. It’s an interesting take on the technology, but does show that human labor is still necessary to actually finish the building. Human labor was required for insulation, glazing, painting, and all interior work. The company believes this technology can be used for affordable housing projects, due to its lower costs.

There is an opportunity to revolutionize the way we protect construction workers from fall hazards while dramatically reducing waste and inefficiency in the construction industry. The Hilmerson Safety Rail System™ was designed and engineered with feedback from industry experts with one goal in mind: Reinvent the guardrail to eliminate inefficiencies, cut costs, send zero waste to landfills, and improve workplace safety.
FieldLens, a web based application available on both Android and iOs, allows for real-time documentation of safety hazards, job site notes, and punch lists. The app eliminates the need to re-type your notes or send separate emails to the correct people, because it can create instantaneous reports on all the information you typed in to your phone or tablet on the job site.
Recently, Fieldlens added three new features that the company says are requested often
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.
It seems like every month there’s a new robot being debuted for the construction industry, with the promise of reducing costs and improving productivity and safety. There are robots for laying brick and block, placing concrete, and even self-driving mining trucks. The most recent robot to hit the job site is Built Robotics’ Autonomous Track Loader (ATL).
Concrete is an extremely strong building material, but has a notoriously weak tensile strength. In order to resist tension, bending, and shear forces, steel rebar or other reinforcement materials are added either prior to the placement or into the mix. Even with reinforcement, concrete is still extremely rigid and prone to cracking. In the event of a major earthquake, the uneven and horizontal forces can cause structures to crack and, in the worst case, cause failure.
Concrete can adapt to any shape its formwork calls for while it’s being placed. While it’s POSSIBLE to make intricate designs with the material, it’s not always easy or practical to do so. Researchers from ETH Zurich have designed a new method of forming and placing an ultra-thin, curved concrete roof system that they plan on installing on a construction project next year.
The immense technological growth the construction industry has seen in the past decade has been a refreshing change, to say the least. Fax machines, large filing cabinets, and redundant work are slowly becoming a thing of the past. More importantly, software developers are actually paying attention to the construction industry, making our lives collectively easier, while giving us more data to make better decisions. Bluebeam, maker of one of the industry’s favorite construction document software, has recently announced a wireless digital sensor specifically for under construction buildings.
In July, we shared an article about a new augmented reality app that would allow iPhone and iPad users to use their devices’s camera as a tape measure. That app, Air Measure, is now available for download after Apple’s iOs 11 release.
As electric vehicles are becoming more and more popular around the world, researchers are trying to find ways to adapt the technology to heavier duty applications. Due to the large size of projects and amount of money in the industry, the mining industry has seen its fair share of technological advancement. Several manufacturers, like Komatsu, have developed and released driverless dump trucks for mining operations in the past few years. A team of companies in Switzerland is now working on a gigantic battery powered dump truck that will be tested for 10 years.
CAT, the name synonymous with heavy construction equipment across the world, has been slowly adding technology to its brand over the past year. Early last year, the company announced it would be releasing a rugged smart phone, which was also the first ever to have a built-in thermal imaging camera. This year, they’re releasing their first step into the world of tablets.
