Rebars in concrete construction are the reinforcing steel that strengthens the material to help create buildings that have structural integrity. Reinforcing concrete means paying attention to the slightest details so the larger the project could go wrong. It may seem easy, when the job reaches completion, for someone that doesn’t have experience but there is a gap between what’s on the outside and inside. The inside is far more complex than the outside. Therefore, it is important for any construction supervisor to know the following aspects of rebar to ensure the success of any building project and move up the ladder in the construction industry.
1. Blueprint and shop drawings
The first thing a construction advisor should do becomes familiar with the engineering plans or blueprint and the shop drawings to make sure they match and work together for the structure’s concrete component. Because these drawings will be in fact sent to a rebar fabricator who then creates a customized reinforcement bar. Therefore it is crucial that on the plan, the lengths, dimensions, and shapes of the materials should be the same.
2. Sizes, shapes, and placement
The size difference between rebars may seem unimportant for your concern at first glance; however, it’s important to check whether the rebar you have chosen is the right one since the slightest error may affect the strength tolerance and the overall performance of your product. Do not ignore the spacing and pay attention to it since it’s what keeps the concrete strength. The same goes for placement. Making a mistake in the positioning will be represented by weakness on the construction supervisor’s side and even greater problems along the way.
3. Tying and splicing
When tying the crossbars or rebars together, you need to anticipate how you’re going to displace the rebar so as to unfold the best tying method when directing your team as they layout and form the rebar pattern. Because you should ensure the overlaps aren’t shortened and the cages are well welded. To maintain the sustainability of the rebars, enough rebars must extend past the forms at the construction joint to be spliced. It is highly expected of you the vertically placed rebar are set in the right position so as to accommodate
4. Coating and proper handling
Rebars should come coated with a rust-inhibiting substance (often epoxy) which is extremely important because it prevents the reinforcing steel from rusting. Uncoated rebars can deteriorate inside the concrete causing the structure to crack and weaken. Coated rebars should be handled with care instilling proper handling techniques. So as a construction supervisor, it is your responsibility to make sure your team uses only epoxy-coated rebars and teach any inexperienced worker on how to lift, move, set, and repair coated rebar.
