Abstract
Purpose - Level of Development (LOD) is a key parameter for describing digital content in a Building Information Modelling (BIM) context. It is seen as an important vehicle for specifying information exchange throughout a facilities lifecycle. However, hitherto there has been little research examining how, beyond the theoretical concept, LOD can be being applied and smartly utilised in practice. This study seeks to unravel the concept and reveal new insights into its application from a design management perspective.
Design / Methodology / Approach - Following a literature and document review, two small-scale case projects were identified. The first to temper the state of the art theory and understand what happens in practice today – discovery led. The second, to drill down to the core of LOD utilisation to support planned model progression and test a plausible novel methodology to automate associated work-flow – theory led.
Findings - Results suggest that a lack of consistent understanding and utilisation exists and particular LOD errors are highlighted, but moreover that LOD can be so much more useful if integrated into a BIM-like workflow. Consequently, a new method of automatically comparing planned model progression with the current state of the model is presented.
Practical Implications - Advancement of the understanding of the concept and application of LOD and its usefulness has significant implications for design information management research.
Originality / Value - Fresh insights into LOD, concept and application are presented. The emerging proposed utilisation framework is novel and targets removal of known labour-intensive activities associated with LOD matrices whilst facilitating rich re-use of efficient model progression knowledge
