Optimising existing digital workflow for structural engineering organisations through the partnering of BIM and Lean processes

Building Information Modelling (BIM) is now seen as one of the leading transformative processes within the Architectural, Engineering and Construction (AEC) sector and has the potential to assist in streamlining the structural design process. However, its practical implementation can often add another layer to the existing workflow and can result, to its detriment, in the primary objective of optimising structural workflows being hindered. This can lead to structural organisations producing 3D models in tandem with traditional drawings, a lack of human intervention regarding software interoperability, and a reluctance to move away from conventional work methods. This paper will explore how a lean approach to BIM adoption can optimise the digital structural workflow, thereby enhancing BIM adoption. Although much research has been conducted on BIM as an enabler of Lean, there remains a gap regarding the synergies in how Lean tools can advance BIM adoption within the structural discipline. The closing of this knowledge gap will be advanced by comparing existing digital workflows within a structural organisation against a proposed integrated BIM workflow underpinned through Lean. The findings highlight that while BIM and Lean offer enhanced digital solutions to modernise structural design office workflows, the true capability of these tools will not be realised without a cultural change.
