Abstract: Formwork plays an important role in building construction. The selection of an appropriate formwork system can reduce project cost, improve quality and speed up the construction process. Although the selection of an appropriate formwork system requires years of experience in formwork design, few experienced personnel may be available, especially in small/medium size contracting companies. With the lack of such experts, the costly outsourcing option becomes essential otherwise the selection of a particular formwork system might not be appropriate. A structured approach is developed to help decision makers in small/medium Egyptian construction companies to select the appropriate horizontal formwork system(s) for their projects. This can be achieved by recognizing the project governing factors affecting the selection process. Based on these factors, a knowledge base is developed to facilitate the process. A fuzzy logic system is used to automate the process and overcome ambiguity and uncertainty in the selection process. The system is shown to be useful and accurate in its application to a real-life case. A survey of formwork experts reveals its ease of use. Further research will expand the system to consider vertical formwork selection to ensure full compatibility.
