Abstract

This paper introduces the concept of Construction Physics as a more comprehensive way of understanding the construction process from a flow perspective. It establishes a preliminary definition of the term and investigates briefly the present knowledge, flow models and methods for their management. From this it argues that the state of the art does not fully cover the whole process and proposes a holistic view of the flow of all prerequisites feeding the process. It introduces the key term Critical Flow and concludes by recommending areas that should be investigated as a joint IGLC research, development and testing programme.
