Introduction



Introduction

New project structures in the building industries:

More and more construction projects are hosted on servers accessible through the Internet.

The engineer is often involved in different projects in parallel.

Therefore, the engineer has to organize his tasks and information across the individual projects.

It is difficult for the engineer to monitor and react to hoc changes in the workflows of one or more projects.


Approach



Approach

Development of a Human Centered WfMS:

The engineer does not have to deal with the different workflow systems of the individual projects by himself.

The system will collect the required information from the individual workflow systems.

Opportunity for the engineer to rearrange his tasks within the boundary conditions of the projects.

Changes will be send to the remote project management system.

Requirements:

Using a standardized format for the exchange of process information.

In order to model the project workflow, a description language for business process should be applied.

For merging different project workflows into a personalized workflow, methods have to be developed that support the user organizing his work more efficiently.

Project information should be visible for all partners, while personal data is hidden.

Workflow Engine: Relational Database based on the IFC

2x Process Model. Database is divided into the Project and

Personal Workspaces. Build in procedures synchronize the

project and the personal workflow.

Client Applications: Project Planning Clients - Initializing and

managing the Project Workflow. Personal Workflow Client - Managing

the Personal Workflow and documents.

Conclusion



Conclusion

Design of a WfMS for the construction industry:

The engineer is the binding element between different projects.

Methods have been developed for merging different project workflows into a personalized workflow.

Ad hoc changes of project activities and user activities will be synchronized.

The design of a two layer database enables the user to obtain access to project information while personal data is hidden.

The implementation of a prototype has demonstrated that such a Personal Planning System can be developed and integrated into a concurrent engineering services platform.
