WP1: Requirements analysis

Objectives

WP 1.2

analyze the requirements of existing data exchange processes in bridge projects

Capture and document user scenarios and use cases for the fast track option,

focus on the use cases already covered by the contributing projects

WP 1.3

Document in detail the purpose and intended use of the fast track IfcBridge data

standard to manage user expectations,

WP 1.4

Prepare these documentations for reviews and manage the reviews with the appointed

international expert panel

it is very important to first define the

exchange scenarios / uses cases

of the IFC extensions to be developed

otherwise the data model might fail to fulfill

the requirements coming from these uses cases

consensus must be found regarding the use cases

to be supported

use case identification was based on the results of

the IFC-Infra Overall Architecture project

Use cases
