BIM and its use in Historic buildings
The existing built heritage is an irreplaceable asset, and a full range of appropriate HBIM fire prevention and salvage data should be incorporated in any BIM4C approach. The seriousness and rigour by which HBIM data should be compiled on the built heritage would do well to acknowledge the high levels of loss already occurring through the effects of fire.
The climate in which conservation work is practiced constantly changes. Increasingly, it is the process of managing change where detrimental forces, such as rising sea levels and storms, are generally unstoppable. In collating relevant HBIM data to help deal with consequential flooding the Report considers the need to devise and incorporate some ameliorating processes.
COTAC’s 2014 Conference Report builds upon information and advice freely offered by the programme speakers. It relates the presentations and discussion outcomes to emerging thoughts on creating a Building Information Modelling for Conservation (BIM4C) initiative by identifying issues that need to be considered in a Historic Building Information Modelling (HBIM) environment.
This Part 1 Report offers some considerations that should be taken into account as the awareness of the particular needs of BIM4C gain ground.
This Part 2 Report aims to identify a wider range of issues and influences that might be contemplated in the development of HBIM. The various Step charts offer a range of ‘key words’ that could be considered and developed as part of the sequential processes that are involved.
This Report founds on COTAC Conference presentations in 2011, 2012 and 2013. Focussing on 3D reality capture techniques informed by the 2013 “A Digital Future for Traditional Buildings: Practical Applications for Survey and Management” event, it aims to start scoping their relevance to HBIM and how that needs to be considered in the context of the traditionally constructed built environment.
At its inception in 1959 the Charity COTAC was Initially concerned about the poor quality of repairs to the fabric of churches. In the interim 57 years, it has broadened its sphere of influence across the construction industry to help address the complex work involved in maintaining, repairing and conserving historic and traditional buildings.

As part of this on-going appraisal and assessment, Ramboll arranged and hosted this
conference ‘BIM4Heritage: Where We Are and Where We Are Going’ in their 240 Blackfriars Road, London Offices, on 9 December 2016. It was held in collaboration with COTAC who, previously, championed the BIM4Heritage concept, spending time developing and gathering
knowledge on the importance of utilising BIM for conserving, maintaining and managing our heritage assets. Conceived as a ‘warts and all occasion’, the conference aimed to offer an honest appraisal
of the use of BIM within heritage buildings and their environments, and to provide guidance on how BIM might be adopted for the range of heritage conservation and repair and maintenance processes. In reviewing the risks and opportunities concerning this specific adoption of BIM and to explore its increasingly advanced applications, speakers were invited to address the topics:
• BIM de-bunked
• Capabilities of information capture
• The conservation Conundrum
• BIM sensitive analysis
• Beyond the clouds
