A target benchmark of the impact of three-dimensional parametric modeling in precast construction

The various direct and indirect benefits that have been identified and assessed were discussed and a conservative set of benchmarks that can be applied as implementation takes place was provided. Some of the benefits were evaluated in economic terms, based on current industry benchmarks of productivity and error rates. Based on these assessments, an example of a large precast company's target evaluation of the economic benefit it expects to derive during the first four years of adoption was described. It was concluded that the directly measurable benefits of building information modeling (BIM) for the precast/prestressed concrete industry are expected to be significantly reduced engineering costs and costs of rework due to errors.
