Consistent Formwork Pays Off
The cost of formwork on a reinforced concrete construction project can be significant — sometimes up to 50 percent of the total cost!
As designers and engineers, it's important to understand how buildings are constructed. It may even help to get a formwork contractor involved at the early stages of the project to provide input to the design.
Uniformity and consistency are key. Select one framing scheme and stick with it throughout the project. Space the columns uniformly and make all the columns the same size. Keep all of the beams and joists the same depth.
By doing this, the formwork contractor only has a few sets of forms that can be used over and over again at the site. The formwork subcontractor will also be able to get into a certain "rhythm" of erecting and stripping the forms that will expedite the project and reduce costs.
