Enabling Lean with IT 811 4D BUILDING INFORMATION MODELING AND FIELD OPERATIONS: AN EXPLORATORY STUDY

The value generating aspects of BIM technology on the virtual design and coordination sectors of construction have been well documented. However, a more thorough understanding of BIM’s ability to assist in the sequencing and implementation of field operations is required in order to fully comprehend BIM’s effect on overall project productivity. For this paper, a case study of a 500,000 ft OSHPD hospital project in Southern California was performed in order to observe, identify, and analyze both the field operational activities which could potentially benefit from 4D BIM integration and the factors that could aid and/or deter successful 4D application in the field. Project data was aggregated over a three month period using a combination of observational studies and open ended interview questions. In order to analyze the data for interactions between field operational activities and 4D BIM applications, a relationship matrix was created. The resulting analysis confirmed that by adding transparency to production sequencing, visualizing trade and equipment movement, and understanding constraints in terms of the site and schedule, the use of 4D BIM could serve as a method through which increased value in field operational activities could be achieved.
