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.

When construction companies initially started to adopt mobile technologies like tablets and smartphones, there was a race between many construction technology companies to be the future leader in the area. As the years rolled on, it became less and less likely that one app was going to be the end-all-be-all, like AutoCAD became in the architectural design world. There’s not one app out there right now that provides every single function that a construction company needs, because each company is very unique. The solution? Integration.
Communication is key to a safe and productive construction environment. One of the biggest challenges of effective communication on job sites is the complexity and size of the project, which inhibits being able to contact the correct people in a timely manner. Tracking devices have been a hot button issue in construction news for the last few years. Some examples include RFID tag sensors in hard hats, such as the one being used on certain job sites in Washington DC and time sheet applications, which allow employers to track their employee’s locations using the GPS on their phone’s or tablets.
In March of this year, Elon Musk announced that Tesla would begin taking orders on their Solar Roof Shingle concept. Tesla Solar Roof is a solar power roof system that eliminates the need for bulky solar panels installed over top of traditional roof materials. Instead, the shingles themselves, which come in a variety of different styles, are the solar panels.
At the company’s second quarter earnings report, Tesla announced that the first solar roof installations have been completed.
[guest post] The progress of construction sites is usually captured by taking still photos of different areas that have been subject to change. Documenting a full construction site requires a lot of pictures (usually more than ten per room), and even then not every corner of a room can be captured.
Standard vertical elevators have had it too good, for too long. After the first cable dependent elevator was unveiled in 1857, not much has changed in the elevator industry. They’re still using cable systems and still only going up and down. But not anymore. ThyssenKrupp has officially made a multi-directional elevator a reality.
Caterpillar is not resting on what made it successful in the past anymore and probably for good reason. The equipment manufacturing giant recently bought Yard Club, a heavy construction equipment sharing company, looking to take advantage of the recently popularized sharing economy. Earlier this month, Caterpillar invested $2 million in Fastbrick Robotics, an Australian robotic technology company.
Augmented and Virtual Reality has always been designated for large headsets. Even with recent developments in the construction industry, like Microsoft Hololens and the DAQRI Smart Helmet, if you want to experience AR, you have to get used to wearing something you’re not used to around a job site. As cool as both of those technologies are, it seems that the ole trusty smartphones and tablets have been overlooked. A Danish BIM company has developed a smartphone and tablet application that leaves the headsets behind.
It’s pretty amazing all of the things that smartphones can do right now. While some wish phones would go back to “just making dang blasted phone calls, like the good ole days,” it’s clear that phone’s will always be more than that moving forward. Through apps and other attachments, phones can now turn into a thermal imagine camera, an x-ray vision scanner to see what’s behind walls, a laser measure, and now an augmented reality tape measure.
For many construction superintendents and project managers across the world, tablets are becoming one of the most important tools on the job site. They’re great for looking at plans, taking pictures, making notes, and running your favorite construction apps. Carrying a tablet does take up at least one of your hands, however, so it can be a hindrance if you need to help a co-worker lift material or climb a ladder.
Fiskars was first founded as a Finnish Ironworks company in 1649, making it one of the oldest companies I have heard of that is still going strong. Recently – relatively speaking - in 1967, Fiskars made a name for themselves with their orange handled scissors. Noted for their build quality, sharpness, and durability, these scissors quickly became an industry standard and a leader in the category. Since then, Fiskars has expanded into other areas of the home and outdoors. You may also recognize the name Gerber, as this is one of the brands Fiskars sells under.
