Use Case Management

The Use Case Management of buildingSMART has the goal to exchange experiences from already implemented or ongoing BIM/VDC projects among experts. Thus, a best practice is generated from individual practical experiences. Use cases are not related to individual project phases but consider the entire value chain (planning / construction / operation / deconstruction).
Each Use Case follows a clear objective and focuses on a specific outcome or benefit. The information requirements for the various actors are determined for each project phas. It is defined who needs what information at which point of time in which format and in which level of detail in order to achieve a specific result.

UCM = openBIM Workflow Enabler

As an integral part of buildingSMART International (bSI) tool set for solutions and standards development, the UCM is a service to capture, specify and, exchange industry best practices and fully supports the openBIM Core Workflow from buildingSMART International. It provides a guided process for developing and sharing use cases with a common language and understanding of BIM applications for the entire built asset industry. It unifies broad experience for numerous BIM projects and makes use cases easy accessible for the whole AECO community.


Results of Use Cases
Use Cases …

  • establish a common language for the BIM/VDC applications of a project and a uniform understanding in the digital value chain from client to user
  • follow a uniform structure and are described consistently throughout all life cycle phases
  • provide the foundation for the definition of BIM/VDC relevant objectives between client and contractor
  • increase the digital capability in the use of the BIM/VDC method for all players in the entire construction and real estate industry
  • define the information exchange requirements and link them to the IFC schema
  • are neutrally formulated and based on the openBIM approach from buildingSMART International.

Methodology
The BIM method in planning, construction and operation of buildings offers great added value. To make the full benefit of this method, the needed information must be available in phase throughout the lifecycle of a building.
Use Case is the starting point of the IDM development. It describes the business need and ideal scenario – including goals and success criteria – for the information exchange. The different parties and their responsibilities are specified with actors and roles. At the same time, their initial activities in the information exchange are also described. Agreements, contracts, standards etc. deal with the external conditions that may have an effect to the objectives or deliverables of the information exchange

The ISO 29481 Building information models - Information delivery manual - Part 1: Methodology and format defines a framework and methods how to present process maps and exchange requirements for a certain purpose
The standard provides a basis for reliable information exchange/sharing for users so that they can be confident that the information they are receiving is accurate and sufficient for the activities they need to perform.
IDMs enable stakeholders across the supply chain to determine their information requirements, by identifying use-cases, mapping processes and define exchange requirements.
The IDM standard is a standardized method for extracting exchange requirements from specific use cases. However, business use-cases are also crucial for translating strategic goals into information requirements. IDM is thereby a suitable methodology for translating business.
IDM is a technical document (physical or digital) that describes business needs, activities and transactions and information exchange requirements for a specific purpose. Business need defines a Use Case. IDM is a way to record and share Use Cases in a harmonized way.

A Use Case consists of the following core elements:

  • Use Case Description Use Cases defines propose and the scope for the information delivery.
  • Process Definition Process definition is made through at least one of the following: Process map / Interaction map / Transaction map
  • Exchange Requirement Information delivery exchange requirements in non-technical formal
  • Information Delivery Specification (IDS) Computer interpretable document that defines the Exchange Requirements of model-based exchange

 

Community
The Use Case Management of is open to the entire community of buildingSMART. All professionals are required to take the necessary measures in their fields and thus actively participate in shaping digitization of their industry. Get involved, work with us and become part of the growing community!

Use Case Management - an initiative powered by buildingSMART Switzerland
The Use Case Management was initiated and developed by buildingSMART Switzerland. The Chapter is responsible for the development and maintenance of the platform. It forms the link to buildingSMART International and ensures a regular exchange with an international steering committee. It is also the direct point of contact for all enquiries relating to Use Case Management.
