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.

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.
Cranes can be some of the most dangerous pieces of equipment on any construction jobsite. Not only do workers need to worry about working underneath loads being suspended by cranes, operators need to exercise extreme caution when working with heavy loads and extreme weather conditions. Cranes are also pivotal in efficiently building multi-story buildings, especially high rise and supertall buildings. The profession itself, at least for tower crane operators, can be fairly lonely though, as there's no buddy system up in the cab. The long commute up to the top also restricts the amount of time operators can take breaks.
The construction industry has been notoriously slow to adopt new technology, so much so that we’re probably –and sadly- keeping the fax machine industry afloat single-handedly. Heck, half of you are probably reading this article on a computer still using Windows 2000. I kid. However, Silicon Valley has recently zeroed in on the construction world, because they’ve realized it’s one of the least tapped into markets on the planet and there are billions of dollars up for grabs. That’s not a bad thing, either.
OSHA gives employees many rights in the workplace and employers many responsibilities. One of those is the employee’s right to see the company’s OSHA 300 Injury and Illness Summary Log and the employer’s responsibility to post it.
Creating and tracking submittals on a construction project can be a pain-staking process. Many times, each submittal is tracked manually via emails or spreadsheet, which leaves companies vulnerable to allowing certain ones to fall through the cracks. Factor in lead times on materials and it could cost your project valuable schedule days or expedited shipping fees, not to mention hours that the office staff spends tracking down paperwork.
Floor layers are broken out into several different categories and this data pull specifically highlights "floor layers, except carpet, wood, and hard tiles." This category most likely encapsulates vinyl tile or linoleum installations, whether they be strips, blocks, or sheets.
As much as contractors would like to avoid working with temperature sensitive materials in the winter, tight schedules or project delays can make that a challenge. Special considerations have to be made in the winter months in order to make sure block walls have a high quality installation and workers are kept safe while doing it.
Insulation workers, specifically those that install floor, ceiling, and wall insulation typically learn their trade on the job. Whether installing more traditional fiberglass insulation or spray foam insulation, these types of workers almost exclusively work indoors. Although there are also mechanical insulation workers, their numbers are broken out separately, as they make an average of $10,000 per year more than floor, wall, and ceiling insulators.
