Abstract:

Temporary construction structures (TCSs), such as formwork and scaffolding, attract a lot of attention due to their impact on the schedule and cost of construction projects. In many cases, the determination of the consumption (i.e., labor, materials, and equipment) of TCSs is a complex process subject to errors. This paper presents a general framework to automatically generate the consumption of TCSs based on the geometry and quantification of building elements in the BIM model, coupled with applicable building codes and industry standards. The framework has been implemented to automatically generate the consumption required for the formwork in a BIM test model. The findings show that the framework provides an efficient way to determine the consumption requirements for formwork. Compared to the current consumption estimating tools for TCSs typically used, this BIM - based tool improves efficiency, allowing the project participants to account for TCSs during the preparation of the project schedules and cost estimates during the early phases of a project. With small modifications, the proposed framework could be applied to other TCSs.
