Abstract:
Historic Building Information Modelling (HBIM) is a novel prototype library of parametric objects,
based on historic architectural data, in addition to a mapping system for plotting the library objects
onto laser scan survey data. The HBIM process begins with remote collection of survey data using a
terrestrial laser scanner. This is then followed by the processing of the laser scan survey data to
generate ortho-image and segmented point cloud data for mapping of library objects. The next stage
involves the design of new shape and parametric rules for the construction of a library of objects that
are based on 18th century architectural pattern books. In building parametric objects, the problem of
file format and exchange of data have been overcome by using Geometric Descriptive Language
(GDL). The final stage in the HBIM process is the development of a mapping system for plotting of
the parametric objects as building components onto ortho-image and segmented point cloud data to
create or form the entire building. The final HBIM product consists of building full 3D models
including detail behind the object's surface, relating to its methods of construction and material makeup.
HBIM can automatically generate conservation documentation in the form of survey data,
orthographic drawings, schedules and 3D CAD models for both the analysis and conservation of
historic objects, structures and environments. HBIM was evaluated through an end users' scenario test
and through consultation with an expert group working in the architectural heritage sector. The expert
group carried out a review of conservation documentation produced from HBIM. In addition, the
accuracy of HBIM was measured by comparing a sample of data from HBIM with related ground
truth data. The outcome of the software testing indicated that HBIM was effective in producing
conservation documentation. Additional design inputs were identified to improve the accuracy of the
system expanding the parameters of the library objects and upgrading the mapping system.
