5 Steps for BIM Standard Harmonization
Step 1 - Alignment of BIM Standards across Works Departments
• To align and formulate a common standards and guidelines for BIM adoptions by
reviewing the current BIM standards and guidelines of works departments
Step 2 - Revision/Revamping of Existing Design BIM
Data according to the Aligned BIM Standards
• Convert and revamp some thousands object models to
the new aligned BIM standards
Survey and Mapping OfficeLands Department
24
Step 3 - Simplified/Shareable BIM • Define common user requirements and
rules for handling on shareable BIM and
data extraction amongst works
departments
Step 4 - Establishment of a BIM Data
Repository for Works Departments
• Develop a common platform for sharing of
BIM data among works departments/works
projects, and supporting BIM/GIS
integration, 3D mapping and CSDI
Step 5 - 3D Map with BIM Use Context to Works Departments
• Design 3D Map with BIM use context to works departments

Data as InfrastructureA strong data infrastructure would enhance the efficiency for
data consumption and sharing
Survey and Mapping OfficeLands Department
28
Data as Infrastructure
Data informs how infrastructure is built, managed and
eventually decommissioned, and real-time data can
inform how infrastructure is operated on a second-to-
second basis.
Data is now as much a critical component of
infrastructure as steel, bricks and mortar. Data is part of
infrastructure and needs maintenance in the same way
that physical infrastructure needs maintenance

Data creates value: leveraging data to get more
