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.

Finding enough labor to complete jobs has been a problem for many companies in the construction industry over the past few years. Amid a construction “boom” in many areas, general and subcontractors are accepting jobs without enough people to work them, so some have turned to hiring “subs of subs” to supplement their work, a report published by The Tennessean says.
OSHA newer and more stringent regulations regarding employee’s exposure to respirable crystalline silica officially went into effect on September 23, 2017. The new reduced the permissible exposure limit of the substance, which is found mostly in products containing sand (like concrete, mortar, and brick), from 250 micrograms per cubic meter of air down to 50 micrograms per cubic meter of air averaged over an 8 hour shift.
Bluebeam Revu is a very popular PDF markup and collaboration tool for the construction industry. Each year, the technology company updates its flagship program to adapt to how their customers currently use the program and makes changes to increase their productivity. Bluebeam recently announced the launch of Revu 2018 and we have a breakdown of all of the changes.
The construction industry has never been one to freely share information without charging a fee. That’s changed slightly recently, with some major players willing to provide useful tools and information to help us become better. For instance, we recently shared that Procore has released hundreds of free continuing education courses on their education platform. Another useful site we’ve found recently has shared dozens of toolbox talks to help your team on the jobsite learn about safety.
It should be obvious that formal safety training is extremely important to running a successful safety program on any construction site. The most common route for construction employers to train their staff is through OSHA 10 and OSHA 30 courses, but, in the past, it was pretty confusing to determine who was actually authorized to teach the courses and where to find them.
Every construction company wants to avoid workplace accidents on their jobsites. The problem is, far too many companies don’t have a structured safety program to help them achieve lower injury rates. The Associated Builders and Contractors, Inc. (ABC) recently released their 2018 Safety Performance Report, which showed how companies were achieving a 670% lower injury rate versus the national average.

Winter is here and with it comes dangerous situations that construction workers don’t have to worry about during warmer weather. Nearly everyone is aware that construction workers should dress warmly in order to prevent medical conditions like frostbite and hypothermia, but what are some of the frequently overlooked risks associated with winter weather?
Tracking progress on any jobsite is extremely important for your schedule and budget. But, as the project grows larger, tracking progress becomes that much more difficult. How do you accurately determine the percentage of work that the subcontractors have completed across 10 stories and hundreds of thousands of square feet?
10 years ago, the most computer knowledge any construction company would require of its applicants was a basic understanding of Microsoft Excel or a scheduling software. Now, construction companies are finally getting wise to the fact that project management and document management software like Procore, Bluebeam, and PlanGrid can provide an efficiency boost to their projects. Because of this, many employers now have job openings that require knowledge of their software of choice.
If you’ve never used that specific software, how can you make yourself eligible for that role?
Concrete finishers smooth and finish concrete surfaces like curbs, floors, and roads. Most are also responsible for cutting control and expansion joints as the concrete hardens. OSHA's new silica dust regulations have added an additional wrinkle to the concrete finishers job, as they are now required to greatly limit their exposure to silica containing dust.
