Impact of BIM and 3D printing technologies on production process and productivity of precast concrete in construction project

Precast concrete (PC) has emerged as a major contributor to this trend, particularly with regard to the construction of tall buildings. While advanced technologies such as Building Information Modelling (BIM) and 3D printing have the potential to increase productivity, their use in the PC production process remains limited. This study seeks to assess the practical implementation of BIM and 3D printing in PC production, as well as their effects on the production process and productivity. A qualitative approach involving benchmarking, observations, site documentation, and semi-structured interviews were conducted. According to the results, the integration of BIM and 3D printing in PC production may increases the precision and accuracy of the finalized elements. The findings showed that 3D-printed PC production could reduce production time by 24% to 53%, highlighting the productivity increases these technologies offer. However, structural strength, integration with MEP installations, and architectural elements must be addressed for widespread adoption.
