This research proposes a new approach for coping with changes during construction: a tool that will identify the scope of the implications of a change as soon as it is proposed, in order to ensure that the stakeholders, involved in the decision process in which change proposals are evaluated, will know in advance if this change might cause the project to stray from its original goals.
The objective of the present research is to assess the feasibility of developing a model that supports the decision process in which change proposals are evaluated, during the design and construction phases of projects. The model is based on the proposition that the building program can serve as a framework for information management, with links to the client requirements and the building design. The model is expected to indicate the scope of the implications of a proposed change by tracing the relationships between different requirements, thus ensuring that the project does not stray from the original goals as expressed in the requirements. The model identifies the implications of a proposed change by using requirements traceability capabilities. It traces the different relationships that exist between the requirements. This is done on two levels: (1) for a specific space, and (2) for the entire project.
The model has been implemented, using Microsoft Excel, to examine its ability to identify the implications of a proposed change, and support the decision process in which this change is evaluated.
In order to test and develop the model, three case-studies have been conducted. In addition, a test-case has been conducted in order to evaluate the model. The case-studies, implementing the model developed in this research, have given positive results, indicating that the model could identify, though in this case in retrospect, the impact of proposed changes. Thus, the model could ensure that the stakeholders, involved in the decision process in which change proposals are evaluated, will know in advance if the proposed changes might cause the project to stray from its original goals. This might have prevented the negative consequences these changes had on the projects that were studied, and which were not identified at the time. The case-studies have also indicated that the model might be feasible for various types of projects, both infrastructure and building construction projects.
