What does a project BIM Manager do?
He facilitate the definition and implementation of:
- BIM Execution Plan
- BIM Goal and Uses
- Responsibility Matrix
- BIM Deliverables
- Delivery Schedules
- BIM Modelling Quality Control
- BIM Coordination
What does a BIM Coordinator for Consultant do?
At Design and Construction Stage
• Create BIM Design Models and Documentation
• Define discipline specific BIM uses including analysis
• Coordinate between BIM modellers , design consultants and cost consultant
• Coordinate with contractor and subcontractors
• Ensure Modelling Quality Control
What does a BIM Coordinator for Contractor do?
At Construction Stage
• Coordinate with design consultants and subcontractors
• Study tender documents
• Review Design Models and Fabrication Models and Drawings
• Use BIM for coordination, sequencing, constructability and cost studies, and field use
• Create construction and as built models
• Ensure Modelling Quality Control
What are the challenges faced in organisation implementation?
- Not enough training
- Senior management to buy in
- No external incentive to use BIM
- Cost of Software
- Mindset Change
- CAD Evolution 01
- Focus on drawings production
- Project’s information in multiple files and formats
- Difficulty to manage changes late in the design
- Risk of data loss during multidiscipline coordination
- BIM best practice and implementation strategies
- Mindset Change
- To many, even until today, still think BIM is an upgrade of AutoCAD mindset
- A perception of drafting tools in 3D
BIM Definition: Drawings
Drawings means two dimensional representations, hand sketches, perspective views or other graphical outputs printed physically or electronically.
As stated in revised Clause 1.10, Drawings will become part of the Model, thus there should not be a distinction between Model and Drawings.
This also results in the deletion of the clause stated in previous condition version, as clause on whether Model or Drawings prevail against each other is unnecessary.
BIM Definition: Model
Model means a digital representation of the Project or part of the Project, and used to describe a two dimensional representation, three dimensional representation, as well as other data representations, including Drawings, as identified in the BIM Execution Plan.
The BPC V2 aims to redefine the meaning of Model, as it is possible to generate many types of data directly from the Model, including Drawings.
Instead of questioning whether a contractual deliverable should be in 2D, 3D, Drawings, BIM etc, the validity of the contractual deliverable should be determined by the content it represents.
BIM Definition: Released Model
Released Model means a Model identified as such and released by the Model Author from time to time as agreed in the BIM Execution Plan.
Definition was previously changed from “Final Design Model” to “Released Model”.
It is possible that multiple Released Models may be made available at the same time.
The descriptions of each Released Model must be clearly documented in the BIM Execution Plan to avoid confusion to Model Users
Also note a Released Model may include two dimensional representations as well.
BIM Definition: Model Author
Model Author means the party responsible for developing the specific content of a Model to the level of detail required for a particular purpose of the Project. Model Authors are identified in the BIM Execution Plan.
Key importance to note
Specific content of a Model
Particular purpose of the Project
As many information it to be embedded into a collaborative BIM modeling, different author uses the model and enter information at different phases for different purpose. This distinguish the model authorship and they shall be defined clearly in the BEP.

What defines a standard?
- A standard is a document that provides requirement, specification, guidelines or characterises that can be used consistently to ensure that processes are fit for their purposes.
- ISO
Who defines a standard?
Government and the interested individual.
Explain why is it necessary to have a standard?
- To avoid fragmentation of practices.
- Produce Consistent Output.
- Easy to understand others input.
- To enable benchmarking.
- To eliminates abortive time and debates.
List the things that needs to be standardised.
- Title blocks
- Hatch Pattern (Filled Region)
- Materials
- Naming Conventions
- Schedules
- Symbols
- Line Patterns, Styles, Weights
- View Template
- Content of each views or sheets
- Browser Organization
- Annotations -Dimensions, Text, Tags, Fills, Symbols and 2D components
- Families / Objects / Libraries
In Particular Condition V2.0 : BIM Management
The Employer shall appoint one or more BIM Managers for the Project.
- All compensation and related costs for the BIM Manager shall be paid by the Employer unless otherwise agreed between the parties in the Project.
- The role and responsibilities of the BIM Manager shall be as provided in the BIM Guide unless agreed otherwise in the BIM Execution Plan.
In Particular Condition V2.0 : BIM Execution Plan
As soon as practicable and from time to time as required, the BIM Manager shall call all parties to the Project involved in the execution of BIM to confer and agree upon the terms of or modifications to the BIM Execution Plan.
- The BIM Execution Plan shall be developed in accordance with the BIM Guide.
- The BIM Manager may not be the lead consultant, but it has an important role to play in exercising the collaboration and coordination process
The parties involved shall use their best efforts to agree upon the terms of or modifications to the BIM Execution Plan.
- The BIM Manager shall
- Maintain a history of all Released Models.
- Schedule and facilitate all meetings concerning BIM.
- Report to and keep the Employer informed on all matters and the BIM Execution Plan, as updated from time to time, shall be subject to the approval of the Employer.
In Particular Condition V2.0 : Risk Allocation
The Contribution of each Model Author is intended to be shared with Model Users throughout the course of the Project.
- It is understood that while specific content of a Released Model may include data that exceeds the required level of detail specified in the BIM Execution Plan, Model Users may rely on the accuracy and completeness of a Released Model only to the extent required for the level of detail specified in the BIM Execution Plan
- Required LOD shall be specified in the BIM Execution Plan
- No Model Author shall be responsible for costs, expenses, liabilities, or damages which may result from use of its Contribution beyond the uses stated in the BIM Execution Plan.
In Particular Condition V2.0 : Electronic Data Exchange
Each party does not warrant the integrity of any electronic data delivered in accordance with the BIM Particular Conditions other than as expressly provided, if any, in the BIM Execution Plan or the Principal Agreement.
