- Description
- Building Information Modeling (BIM) provides a means for owners, designers, contractors, and operators to generate, organize and use detailed information throughout a project lifecycle. An important aspect to the success of BIM is the process in which information is exchanged between project team members. In theory, information should be both accessible and usable, when required. Because the AEC industry is project centered, and several companies work collectively towards the design and construction of a facility, the availability and accuracy of information can become constrained. Building Information Modeling has the potential to improve efficiency in the AEC industry; however, if the information exchange (IE) process is not planned early in the project lifecycle, the benefits of using the authored data may be mitigated by process waste.
This paper serves to evaluate the value of early team planning as it pertains to performing BIM tasks in the construction phase of a project. The rationale behind lean theory is to increase efficiency by eliminating waste, consequently increasing value. To illustrate the value of early project planning for BIM, this research focuses on the information exchange waste produced on a case study project. During the case study process actual information exchanges were evaluated using the seven types of waste: overproduction, inventory, extra processing, motivation, defects, waiting, and transportation. Finally, time and resources were allocated to each
non-value added aspect of information exchange through interviews with the project team members. This procedure produces a total cost of IE waste which was then correlated to the lack of early planning. Using this methodology, the Millennium Science Center (MSC) project on the Pennsylvania State University campus was evaluated to determine the economic benefit associated with the early planning of BIM on future projects.
