Snow causes all kinds of travel nightmares and not just on the roads. Snow and ice can cause major airline delays and flight cancellations. Because of these issues (and the large amounts of money to be gained by solving them) several different groups of researchers have been hard at work figuring out ways to reduce and remove snow and ice from pavement without the need for chemicals and snow plows. The first technology to get a full scale test slab installed at an American airport, however, came from Iowa State University professor Halil Ceylan.
The Des Moines International Airport has been testing two 15 foot by 13.5 foot test slabs of Ceylan’s electrically conductive concrete since Fall of 2016. Throughout the winter, which happened to be fairly mild, the heating elements in the test slabs were manually managed through the use of a smartphone app.
Unlike another heated concrete that Construction Junkie wrote about that contained 20% metal and carbon particles, Ceylan’s design only uses 1% carbon fiber. Each test slab is a total of 7.5 inches thick placed in two layers, with just the top 3.5 inches are electrically conductive.
Each square meter (10.7 square feet) uses about 333 watts over 7 hours, totalling to around 19 cents in additional electric costs. The team of researchers is using plenty of tools to help them determine just how well the slabs are performing, including temperature probes, strain gauges, humidity sensors, surveillance cameras, and thermal imaging cameras.
The project has over $4.4 million in funding, split between the Center of Excellence Partnership to Enhance General Aviation Safety, Accessibility, and Sustainability (PEGASAS) and Iowa State University.

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.
