Leinster House, currently the seat of the Parliament in Ireland, was constructed in 1745 for the Duke of Leinster as a country House. The Discovery Programme is creating a Historic Building Information Model (HBIM) of Leinster House to support its conservation and management. The paper describes the HBIM workflow, the challenges faced and techniques being used by the Discovery Programme to create a solution and protocols that can be used on other historic buildings managed by the Office of Public Works in Ireland. The project to create the HBIM is a partnership involving the Discovery Programme, Carleton Immersive Media Studio and Dublin Institute of Technology.

4. BIM – Building Information Model(ing)
intelligent model-based process that provides
insight to help you plan, design, construct, and
manage buildings and infrastructure

5. HBIM Challenges
modelling methodologies and approaches which
will document deformities whilst retaining BIM
functionality

6. Scan to BIM Workflow

15. Big Data Problems

16. Data Organisation
Segmentation of the point cloud into regions corresponding to
floor plans allow the data to be used in workable parts.

26. HBIM Challenges - Attribution
Improvement of the attribution of HBIM to
ensure additional full and descriptive
documentation of historical buildings is enabled

29. HBIM Challenges
Application of BIM to OPW future work
including: Internal management of BIM data,
conservation documentation policy, facilities
management and specification of future works
• LOD expectation
• Conditional Survey – Smallest component
• BIM ready staff in OPW
• Perceived Uses

30. HBIM Challenges
Creation of HBIM solution and protocols which
can be applied to the full range of OPW historic
buildings
