The Royal Institution of Chartered Surveyors have spotlighted Building Information Modelling implementation on a current, historical build, as opposed to the construction of a new project.
“There has been no serious work initiated to date in determining how BIM can be applied in the conservation sector of the UK construction industry.” – A controversial point yet a one that is backed up by Kavanagh further, who said: “Work to existing buildings comprises over 40% of UK construction industry output and yet critical aspects of current BIM thinking fail to consider this.”
With that thought in mind, Kavanagh references Heritage Cottage in Wales, a small project that has seen historic BIM (HBIM) implemented to “aid proper management and maintenance” as opposed to being used for redevelopment purposes.
Kavanagh described HBIM as “a ‘rich content’ information management system for heritage buildings”. Whilst normal BIM models will certainly have a high level of detail, HBIM requires even more precise and intricate models complete with heaps of information and data.
Like modern BIM projects that featured product information to assist facilities managers, HBIM models have similar information plus more that relate to historical events that are synonymous with the property. Kavanagh makes note that a screw in a garden gate, a fireplace which was cast in 1854 and original box sash windows are all in the model and are accompanied by incredible information such as data sheets with photographs and historical facts.
Kavanagh closes by stating that whilst the Heritage Cottage BIM is a small project, it paves the way as an inspiring case study that BIM Managers and the like can study for the future. He stated: “This may seem a bit academic but Heritage Cottage is attempting to highlight best practice to mainstream industry and others who own and manage older homes. The most important aspect will be the optimum data and learning resources to aid proper management and maintenance that will result from the exercise. This could be the way by which BIM for existing buildings can be seen as a very valuable tool in the future.”
