Abstract
Abstract Formwork is a supporting tool for printing concrete of the desired size and shape. Choosing a certain type of formwork method will affect the time and cost of a project. There are two types of formwork method, the conventional method and the semi-system method. This research will compare the two methods on the cost, time and waste products on their application on beams, columns and slab of a construction building project. The aim of this research is to compare the cost, time and waste product of the two formwork method on a construction building project. A high rise construction building project with 24 floors will be used as a case study in this research. Based on this research it is found that the conventional system cost 12% more than the semi-system. It also needed 12 more days to finish and also produce 10% more waste than the semi-system.
