Specialty contractors have knowledge to contribute to the early design of architecture, engineering, and construction (AEC) products. In current practice, however, they are seldom involved in early design, but evidence suggests that their early involvement is increasing. Lean construction theory advocates such involvement. The practice of involving(More)
This paper presents a process simulation model representative for design development of a building system in an unpredictable environment. Unpredictability means that design criteria are prone to change as design development unfolds. The model was implemented with a discrete-event simulation engine based on event graphs. Events capture moments when tasks(More)
In unstable environments, characterized by frequent client-driven changes in design criteria and by huge pressure to compress project delivery times, practitioners must search for innovative ways to structure the design-build process. Involving specialty contractors from project inception onwards, helps to satisfy client needs. Based on empirical research(More)
