A web-based system for design interface management of construction projects

Planning methods such as CPM and PERT cannot model the iterative details of design processes. It has been demonstrated that the Dependency Structure Matrix (DSM) is an effective method to model iterative process. However, formulating the DSM on large construction projects, using current methodologies is challenging. To address this challenge, a structured methodology called Design Interface Management System “diMs” has been proposed. As the documents and interactions required for implementing the “diMs” process are voluminous, support of an IT based tool is essential. This paper presents the design and the development of the tool. It includes the design of class structure, relational database and communication engine using object oriented concepts. In addition, the design of user interface which consists of a set of dynamic web pages is also explained. The paper also illustrates the usage of the tool for the design of a glass factory and discusses the utility of the tool in assisting design interface management.
