Analyzing the Efficacy of a Suspended Concrete Slab in Formwork and Concrete Construction

Analyzing the Efficacy of a Suspended Concrete Slab in Formwork and Concrete Construction

It gives a sense of relief and comfort to know that your house is constructed on a solid base. Analyzing the base of the building that you are working on is crucial. The analysis must be done before the concrete is poured. Analyzing it after the concrete is poured makes it difficult for one to tell or see any deformities or issues within the formwork or the concrete structure. Failure to do this may result in unnoticed defects finding their way into the structure. At this point, the damage will already be done and it will be too late or very expensive to undo it.

This article is for any surveyor’s inspector that needs tips to guide him or she analyzes the efficacy of a suspended concrete slab. Below are the secrets that you need;

Step One: Check for the Support at Maximum Moment

This is normally done according to the engineer’s plan. While at it, always check the shape of the bending moment. Remember to do more than just checking for adherence from the blueprint or the drawing.

It is important as an analyst to know where more support is needed. Find out if the maximum support of the suspended slab positioned corresponds to the highest tilting moment. Always aim for something better than the minimum standard.

Step Two: Identify Where the Supports are Located

Make sure that the supports are exactly where the layout engineer thinks they are. They should be correspondent to the blueprint or the drawings. There are a lot of concrete constructions where its builders used limited supports than how the engineer had earlier anticipated. To identify where the supports are located you should;

  • Check if the support that from the columns are in line with the blueprint
  • See whether the load-bearing walls are constructed on the suspended slab’s underside
  • Check whether the suspended concrete slabs are joined to the wall or not

Step Three: Confirm Whether the Concrete Strength Used is the Correct One

This step is very crucial because not all concrete constructions and formwork use the same concrete strength. The drawing or the blueprint should clearly state what kind of concrete strength is to be used on the project. On also inquire from the builder on the type of concrete strength to be used. Concrete strength depending on the structure has a lot of importance. For example, high-performance concrete has enough strength to withstand a lot of weight.

This means that the concrete’s strength will determine the durability, serviceability, and porosity of the surface.

Step Four: See Which Supporting Layers are positioned first and last

Ensure that the builder has positioned the steel correctly. Steel support that is closer to the tension face is usually the most effective one. If a mistake is found, then more steel can be placed before the concreting process. Use the drawing or blueprint and make sure that the steel is placed correctly

Step Five: Suspended Concrete Cover in Concrete Construction

Before the concrete is poured always make sure that the correct cover is usually used. Check whether the suspended slab support is properly positioned in the slab. In a situation where the whole thing is too close on the surface, the steel might end up corroding and disappoint.

In situations where tapes are used, you can always pull them off to confirm the upper and bottom cover.
