Minimized communication protocol based on a multi-LOD meta-model for adaptive detailing of BIM models

A continuous generation and evaluation of design variants characterize the conceptual architectural design stages. Variants comparison is a crucial process for making design-detailing decisions. Objectifiable criteria, including results of simulations and analysis, used for evaluation and comparison of design variants can legitimize decisions as the design process proceeds. A major challenge today is the management of design information and collaboration among several actors in a building project. Yet, a large portion of the Architecture, Engineering and Construction (AEC) industry deals with conventional methods to exchange design information. The growing use of building information models is promising but even the most recent developments and practices still rely heavily on human-readable protocols and issue management systems. Considering the potential of schematized computer-readable communications to be analyzed and used for future references and case-based reasoning systems. This paper proposes a novel minimized communication protocol that aims to introduce a computer-readable, yet adaptive universal method which works on schematized information exchange requirements (templates) for different use cases. The concept is demonstrated using an example scenario.
