Construction Productivity Graph. A Structured Framework to Enhance Productivity and Safety on Construction Sites

The construction industry is characterised by the constant production of unique products in dynamic contexts where, moreover, the workplace coincides with the product itself. This limits the adoption of standardization and process automation methodologies. Furthermore, the average size of professional firms and companies often does not allow for investments in process innovation or skills development. Then, we need to consider that construction is a highly risky activity, also to the lack of standardization as aforementioned. The paper aims to present the framework of a methodology based on linking the information managed by a BIM model with Agent-based simulation techniques - ABS. The scope is to simulate the duration of the work under efficient conditions, understood as the best occupation of the available areas by a suitable number of workers. The result is the Construction Productivity Graph - CPG, a graph that indicates the optimization level of the construction process.
