Numerical modelling and cost-duration analysis of roof structure design changes

Determining building design and type of material is very important before initiating a construction project because structural design changes can impact the project's cost and duration. This study will discuss the impacts of such changes in building design, both on structure and on cost and duration. It will focus on a case study of a showroom office building that intends to change the design of its roof from concrete to steel frames. The research will be carried out using the Finite Element Method numerical modeling, as well as cost and duration analysis. The use of steel frame may shorten the construction duration while the use of concrete roof may lower the cost.
