Formwork is the temporary moulds in the construction which are fabricated based on drawing and design of the structure and into which the concrete is poured to form the required structure. Formwork is an essential part of the construction as it has been in used by the Romans. The formworks must be strong enough to withstand all types of the loads. The joint must be in proper conditions to avoid any kind of leakages. The materials used for the formworks should be economical, easily available and durable. The formworks can be made up of different materials such as plywood, steel, aluminum, composite material etc. In Steel formwork the plates used for the slab support are made up of galvanized steels and these are fabricated as per the requirements. Aluminum plates are used in the aluminum framework along with the other components made up of aluminum. The selection of the suitable framework is important in any project because it bears about 25 to 30% cost of total cost of construction. In the present study, different types of formworks such as steel, plywood and aluminum were studied in a project and a comparison was made on the reusability and easiness in handling and maintenance. Also, comparison for the formwork used in construction of 5th and 11th floor tower based on the specific plan and drawing was done. The results showed that the aluminum formwork was found to be efficient and suitable among all formworks, although the cost was higher compared to other formwork’s materials.
