Abstract

Steel structures are a very popular type of buildings. They are usually preferred in construction as opposed to regular concrete buildings mainly for reduction of construction duration. For building steel structures, standard hot-rolled sections or customized built-up sections can be used. Each of these two options has different parameters that would affect project cost and duration. There are more activities associated with building a structure using built-up sections, and hence, such an option is expected to have a longer duration than using standard sections. Also, using built-up sections usually would result into less weight of the structure than using standard sections. A third factor that should be taken into consideration, while assessing cost effect, is the basic market price of the raw material of each of the two options. There are hardly any tools that predict difference in duration or total project cost between building a structure using standard sections and built-up sections. Therefore, a simulation model using AnyLogic® tool is developed in order to simulate the durations of activities associated with preparing and assembling the built-up members. A case study of a steel structure is discussed where two different design proposals are given, one using standard sections and another using built-up sections. Each of these two options have different members, weights and durations for workshop activities. The model’s objective would be to assess duration and cost of each of the two scenarios in the workshop phase and without the construction phase, and to compare between them. This model can be used as a guide for evaluating different design proposals for a given project and to optimize predictions of durations and costs for each proposal, which shall help in achieving the optimum bidding strategy. Upon simulation, it was proven that the factor with the highest contribution to decision-making criteria for choosing between a built-up or a hot-rolled proposal for a steel structure is the base price of the raw material for each option in the market.
