Transition from PAS 1192 to ISO 19650

You should know the Transition from PAS 1192 to ISO 19650, changes in BIM standards, naming convention in ISO 19650, and how ISO is different from PAS 1192.

What Is ISO 19650?

ISO 19650 is an international BIM standard that provides better control over the lifecycle of a built asset. ISO 19650 promotes better collaboration and management of information and helps construction professionals to reduce risks from the design process.

How Is ISO 19650 Different From PAS 1192?

The concept of ISO 19650 remains the same as PAS 1192 standards. There have been slight changes in the reference terms and language.

Mentioned Below Are The Notable Changes In The ISO 19650 :

  • ‘Stages’ is the new term for BIM levels
  • BIM level 2 is almost obsolete in ISO 19650 standard
  • Appointing and appointed parties are new terms for employer and supplier
  • Offers comprehensive lifecycle information concepts
  • Federation strategy and container breakdown are new terms for volume strategy
  • Availability of information is simpler for project stakeholders
  • ‘Areas’ replaces ‘states’ and ‘suitability’ replaces ‘status’ in CDE
  • ‘Exchange information requirements’ replaces ‘Employer’s information requirements
  • The level of definition is now termed as Level of information

Monitor Major Performance Outcomes

1. Appointing Party
Appointing party is the owner of the project. After all the appointing party manages all the information provided by other project participants.

The Responsibilities Of Appointing Party Include:

  • Developing Project Information Requirements (PIR) and setting project goals
  • Creating a common data environment for the project stakeholders
  • Preparing methods for information management
  • Recording the experience with the lead appointed part

2. Lead Appointed Party
Client/appointing party assigns the lead appointed party. Also, the lead appointed party can subcontract the work to its other vendors and suppliers.

The Major Responsibilities Of The Lead Appointed Party Include:

  • Developing BIM execution plan, master information delivery plan (MIDP)
  • Managing the development of information models created by the delivery team
  • Appointing resources within the delivery team as per the project requirements
  • Developing contracts for lead appointed party
  • Conducting quality check of the information models prepared by the appointed party

3. Appointed Party
Lead appointed party assigns the appointed party. Even more, BIM engineers, designers, suppliers, vendors, etc. come under the appointed party category.

The Responsibilities Of The Appointed Party Include:

  • Assisting lead appointed party with creating BIM execution plans
  • Developing information models and project information models for the project
  • Preparing task information delivery plans across the team
  • Agreeing on the deadlines set for the delivery of information
  • Attending project review meetings with lead appointed party

To Simplify The Hierarchy Of Different Project Stakeholders, So The Table Below Categories The Team And Roles:

Information Container

Information container stores unstructured and structured information. Geometrical models, pdf documents, and excel spreadsheets are good examples of information containers.

Information Model

Several information containers together create an information model. Moreover, an information model has both graphical and non-graphical information. A conceptual design Revit 3D Model is a good example of an information model.

Project Information Model (PIM)

PIM consists of information devouring during the delivery phase. Although, this contains all types of information such as models, databases, spreadsheets, and documentation. Common data environment stores project information model. PIM develops throughout the project.

Asset Information Model (AIM)

AIM consists of necessary asset information. The operational phase of the project requires asset information. Some information from PIM gets transferred to AIM. It also contains graphical and non-graphical. This includes maintenance, lifecycle, and operational information of the project.
