Try to imagine .0015 inches, it’s not easy to visualize. Now, rip one of the hairs off of your head and that’s about half of the .0015 inches, which is the allowable variance of a concrete floor that one contractor is working on right now.
Lodge Manufacturing, the company that sells the extremely popular Lodge cost iron cookware, is building a 212,000 square foot distribution center in Marion County, TN that will consolidate all of its 4 current warehouses into one building. The new warehouse will be equipped with wire guided lift trucks that will stack and retrieve the cast iron products on the shelves. As pallets of cast iron products can way in the tons, the concrete floor beneath the trucks had to be extremely flat, reported the Times Free Press.
Morgan Construction Co. and Eldridge Concrete Construction took on the challenge of placing the concrete floor, which spanned almost 4 football fields in length (1,200 feet), with a variance of only .0015 inches.
That’s incredibly precise and may be the flattest concrete floor in the world, according to Walter Ford, who is the vice president of operations for Morgan Construction. "We worked really hard to maintain ideal conditions with temperature, lighting and the concrete mix to get the flattest floor imaginable," Ford said in a statement.
Environmental conditions can play a huge role in how the concrete cures, so everything had to be perfectly planned in order to achieve the results. Subgrade conditions will undoubtedly play a future factor in whether or not the floor will continue to stay as flat as it is, especially when the weight of the cast iron is placed on the floor. Regardless of the final outcome, placing the concrete with that small of a variance is an extremely impressive achievement.

After sharing average hourly wage data for construction laborers, ranked by state, a little over a week ago, I’ve decided to begin doing the same for the other many different construction related professions. Our second profession that we’ll be analyzing will be heavy equipment operators.
The construction industry is in need of workers and the industry is generally struggling to attract younger workers to the job site. There’s real money to be made in the construction industry, even more so than many other industries. According to the U.S. Bureau of Labor Statistics, the average yearly median pay for those in the construction industry was around $6,000 higher than all other occupations.
In June, we shared that OSHA was planning to extend the deadline for crane operator certification requirements until November 10, 2018. Last week, on August 30, OSHA made that official and issues a Notice of Proposed Rulemaking.
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.
[guest post] A punch list is a vital part of a construction project’s contract. It helps ensure that the contractor has completed the project in a satisfying manner and that all issues, such as damage to any structures as well as incomplete or incorrect installations, are taken care of before being paid.
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.
[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.
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.
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.
According to OSHA, more than 40 percent of all heat-related worker deaths occur in the construction industry. Many more workers also become ill from extreme heat and humidity. With summer now in full effect, it’s time to re-evaluate your personal steps for keeping safe in the heat and how your company is going to help their employees stay safe.
