1. GOVERNANCE MODEL FOR CLOUD COMPUTING IN
BUILDING INFORMATION MANAGEMENT
ABSTRACT
The AEC (Architecture Engineering and Construction) sector is a highly fragmented, data
intensive, project based industry, involving a number or very different professions and
organisations. The industry’s strong data sharing and processing requirements means that the
management of building data is complex and challenging.We present a data sharing capability
utilizing Cloud Computing, with two key contributions: 1) a governance model for building data,
based on extensive research and industry consultation. This governance model describes how
individual data artefacts within a building information model relate to each other and how access
to this data is controlled; 2) a prototype implementation of this governance model, utilising the
CometCloud autonomic cloud computing engine, using the Master/Work paradigm. This
prototype is able to successfully store and manage building data, provide security based on a
defined policy language and demonstrate scale-out in case of increasing demand or node failure.
Our prototype is evaluated both qualitatively and quantitatively. To enable this evaluation we
have integrated our prototype with the 3D modelling softwareVGoogle Sketchup. We also
evaluate the prototype’s performance when scaling to utilize additional nodes in the Cloud and to
determine its performance in case of node failures.
