IHBC CPD Boost: New ‘Heritage Science BIM’ report from HE, with added context from COTAC

Both the IHBC and COTAC have welcomed the new Historic England (HE) Report on ‘The Application of Building Information Modelling (BIM) within a Heritage Science Context’, while COTAC (of which IHBC is a member) helps set this work within the wider mainstream of its building conservation initiatives.

COTAC Chair Ingval Maxwell: ‘We are delighted to welcome this work in its heritage science context.  It is also worth highlighting the link between this work and key COTAC reports, as well as the ‘BIM for Heritage’ volume also for Historic England, by Sofia Antonopoulou and Paul Bryan.’

‘The Historic England publications are part of wider developments developing from the ‘BIM4Conservation Group’ that COTAC initiated in 2015, and the consequent 2016 on-line pdf publications ‘COTAC BIM4C Integrating HBIM Framework Report’: Part 1 ‘Conservation Parameters’, and Part 2 ‘Conservation Influences’.

Barry Bridgwood, Adviser to COTAC and IHBC member, said: ‘Historic England’s ‘The application of BIM…’ publication, by Carl Brookes, of Ramboll, is excellent, and really establishes the fundamental difference in approach when dealing with heritage assets and resources.’

‘The information modelling achieved by modern electronic methods is very informative and useful, as well as the fact that Heritage projects require much more ‘front loaded’ information on understanding significance prior to intervention.  Altogether it represents excellent progress in recognising why and how heritage projects, within the BIM context, are fundamentally different to new build!’

‘As part of these congratulations, we would also highlight the need for training on conservation matters at professional qualification stage in order to ‘alert’ student and /practitioners to the very great differences when undertaking heritage projects’.

Historic England writes:

BIM is the widely used acronym for Building Information Modelling, a process of digitally representing the physical and functional characteristics of a building. Given that the majority of UK BIM application is currently focused on new build design and construction, Historic England commissioned Ramboll to identify relevant processes and datasets that would potentially allow heritage sites to be managed and heritage science focused analysis to be undertaken using BIM procedures.

To provide a heritage focus and relevant, derived datasets two important Grade I listed sites were selected – the medieval, oak framed Harmondsworth Barn built in 1426 and The Iron Bridge over the river Severn built in 1779.

Using existing geospatial survey datasets for both two sites Ramboll considered how a BIM environment could benefit heritage science analysis and processes. This involved building examples to illustrate established BIM metrics such as level of modelling definition, level of detail, level of information and measurement classification to achieve the required fidelity of model

Additional COTAC reports
Based on the 2014 COTAC Conference presentations, three additional reports consider what might also influence gathering HBIM data:
