Using a change control system and building information modelling to manage change in design

摘要

Today, there are few satisfying change management systems to handle changes in design, both internal changes initiated by the engineering team and external changes initiated by the client. How can changes in design be managed using a change control system (CCS), and how can building information modelling (BIM) be utilized to optimize evaluation of changes? This paper introduces a change management process and a corresponding CCS for managing changes in detailed design, and assesses how BIM can be used to identify consequences of changes. Findings are based on experiences from execution of major oil and gas projects. Data are gathered from projects, primarily through a Norwegian engineering, procurement and construction (EPC) contractor, using case study research. The research portrays how changes can be handled using the CCS. When a design change request is created, it is presented to a Change Board, where it is processed, categorized, evaluated and either approved or rejected. BIM is used to consider impact and consequences for affected disciplines. The client will be added in the decision process and presented for cost and schedule impact Results indicate that the dynamics of the CCS combined with the utilization of BIM can keep control of changes in detailed design and reduce overall impacts of changes.
