Unintended consequences: Why a LOD400 model is not always desirable

Building Information Modelling (BIM) has brought about significant improvement to the Architecture, Engineering and Construction (AEC) industry. As this article will explore, however, is that the enforcement of specific BIM deliverables can be counterproductive and result in worse project outcomes. Specifically, the article unpacks the requirement of a fabrication-level model, known as ‘LOD400’.

When challenging the fitness-for-purpose of BIM, some readers may be inclined to jump to the conclusion that if you are challenging BIM, you must be advocating CAD. This assumption is misguided. For those that know the work of Parametric Monkey, they will recognise that our positioning is based on a deep understating on BIM’s strength and weaknesses and current industry trends. This article is therefore not about reverting to CAD, but rather questioning how together, we can improve the BIM process to achieve better things.
