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.

Early in 2018, PlanGrid announced that they would be organizing their very first annual Construction Summit, which would unite PlanGrid users and stakeholders in the company’s home city, San Francisco. At the Summit, which took place on June 10 and 11, 2018, PlanGrid CEO Tracy Young and CTO Ralph Gootee chose to announce several major product innovations and developments.
Construction Junkie's 4th 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.
Tracking updates to construction software is uncharted territory for many contractors and very easy to miss. I’m going to be highlighting a lot more software updates and enhancements for several of the major project management and construction productivity software that many construction professionals are using in the future. Recently, PlanGrid announced 7 new updates that its users will most certainly find helpful.
Creating submittal logs and tracking forms can be a complete hassle, so thankfully tech companies have taken notice and have begun creating tools to alleviate the problem. Earlier this week, Procore announced the release of their new Submittal Builder tool, which will scan your project’s spec book and create a submittal log within minutes.
One of the biggest hassles of site work in construction is the hauling away of spoils. It’s costly and time consuming to bring in truck after truck to take unneeded soil off to an unknown dump site. When Elon Musk and his team, The Boring Company, started digging a tunnel for a HyperLoop system in Los Angeles, they knew there had to be a better way to handle to soil than to haul it away.
Welcome to another exciting year of Construction Junkie’s Best Construction Podcast competition, 2018 edition. This is our 4th straight year running the competition and this year’s already shaping up to be the best one yet.
Built Robotics’ Autonomous Track Loader (ATL) first made headlines late last year when it began beta tests on small test tracks in San Francisco. The ATL is powered by a rooftop cargo carrier that is filled with electronic equipment, including Light Detection and Ranging (LIDAR). LIDAR utilizes a pulsing laser in order to measure distance and range from objects around it.
In the ever evolving power struggle for the major tool manufacturers, converting users to their personal cordless battery powered platform is paramount. With new battery technology hitting the market, we’ve seen tools that we never imagined would ever be able to be run off of a battery platform even outperform their corded version. DeWalt has recently made another huge advancement in battery technology with the announcement of a new 12.0Ah battery.
