Project BIM Standards

Common BIM Standards should be established and agreed between all Project Stakeholders. This can take the form of an established industry standard (such as the AEC(UK) BIM Standards) or could be an agreed project specific standard.

The BIM execution plan should document the overall Project BIM objectives. These should be discussed and agreed between all Stakeholders. The selection of these objectives will be dependent on many factors such as:

  • Client Requirements
  • Stakeholders Requirements
  • Stakeholders Skillsets
  • Project Fee Levels

It can be helpful to prioritise the Project BIM Objectives into Primary and Secondary Objectives.

Note: Project BIM Objectives will change in line with various phases of project development.

Project Stakeholder’s BIM Objectives

As well as the agreed Project BIM Objectives it is often the case that individual. Stakeholders will have their own BIM Objectives running in parallel. Documenting these can help promote a better understanding of individual Stakeholders approaches to BIM.

Programming

Project BIM Objectives and Goals will change in line with the project phases. The programming of the agreed Project BIM Objectives must be taken into consideration and agreed between all Stakeholders. Document the programming of the Project BIM Objectives within the BIM Execution Plan.

Level of Development Matrix

To assist in the exchange and delivery of collaborative BIM data it recommended that all Stakeholders collectively develop and agree a Level of Development Matrix. The purpose of this matrix is to plan and communicate the collective BIM deliverables. It should address the following items:

  • Who is modelling each element?
  • When each model element is being modelled.
  • To what Level of Development is each element being modelled?
  • Who is the responsible stakeholder for model elements at each stage?
  • What is the authorised use of each model element?

Project BIM Standards

Common BIM Standards should be established and agreed between all Project Stakeholders. This can take the form of an established industry standard (such as the AEC(UK) Standards) or could be an agreed project specific standard.

Project Coordinates

Establishing agreed Project Coordinates is essential to efficient collaborative working.

This should be established and documented at the soonest opportunity.

For Example:

  • Geo-referenced
  • Locally referenced origin point

Modelling Standards

Common modelling standards should be established between all Stakeholders.

Examples of areas of consideration could include:

  • Modelling Methodologies. (3D, 2.5D, Placeholders etc.)
  • Level of Development.
  • Level of Detail. (Revit Specific)
  • Incorporation of Meta data.
  • Use of Material properties.
  • Use of In-Place Families (Revit Specific)

Communication & Meetings

Efficient and regular communication is essential to the running of a BIM based project.

To facilitate this regular BIM project meetings are to be encouraged. The frequency of these meetings may vary as the project progresses however they are an essential part of a successful BIM project.In addition consideration should be given to potential co-location of Project Stakeholders. This has been proven to improve Stakeholders’ communication and encourage efficient collaborative working.

  • Level of Detail. (Revit or ARCHICAD Specific)
  • Incorporation of Meta data.
  • Use of Material properties.
  • Use of In-Place Families (Revit Specific)

Data Exchange Protocols

The regular exchange of BIM data is an essential part of a successful BIM project. All

Stakeholders should establish agreed Project Data Exchange Protocols. This should include the following:

  • Method of Data Exchange (Shared Data Environment / Temporary Shared Area /
  • Direct Access)
  • Use of Work In Progress (WIP) data.
  • Agreed format of exchanged model data.
  • Model naming convention.

Model / Data Validation Protocols

All Stakeholders should have in place suitable procedures for Model Data validation for both issuing and receiving BIM data. In addition each Stakeholder should in place documentation confirming that these procedures are being followed throughout the life of the project.

For Example:

  • Model Transmittal documentation.
  • Model Validation documentation.

Model / Data Subdivision

BIM projects often require the segregation of data into manageable sized pieces. This can take many forms and is often unique to each project. Describe and diagram how the project model data will be subdivided.

For Example:

  • Number of models for each discipline.
  • Subdivision of key worksets within each model.
  • Details of linked models within each sub model.
  • Details of model link types (Overlay / Attachment)

Modelling Units

Common modelling units should be established and agreed between all Project Stakeholders. This becomes may take on a greater importance when working with international Stakeholders.

For Example:

  • Metric / Imperial

BIM Mock-up

As part of planning BIM data exchange methodologies it may be beneficial to test the exchange workflows prior to commencing the project models. This process can help establish the most efficient ways of collaboratively exchanging information as well as reducing the risk of problems later in the process.

Area Calculation Methodology

Common agreed methods and standards for area calculations must be establishedbetween all Stakeholders.

For Example:

  • Gross Internal Floor Areas
  • Net Floor Areas
  • Embedded Carbon
  • Energy Modelling
