Although the focus remains primarily on high resource efficiency, the significance of flow efficiency in construction is continuously increasing. Flow and resource efficiency describe two competing target viewpoints, which focus on reducing non-value adding activities and maximizing resource utilization, respectively. Recent research has shown that balancing both perspectives provides a viable solution. However, the exact...

For many years traditional project delivery methods have been utilized in the construction industry, but new delivery systems such as IPD are being developed to answer the need for more integrated approaches. Studies have been conducted to assess the impact of project delivery method on project performance, but few focus on the effect of team...

The construction industry has experienced many inspiring improvements. Especially two movements have introduced innovative design and construction practices: The advancement of lean thinking and tools and maturity in applying BIM and related concepts and technologies. Although Lean and BIM often thrive in the same culture, have many similar properties and strong potential synergies, they are...

In this study we contend that the conceptual foundations of conventional construction design and design management are obsolete, and these need to be substituted by a more comprehensive theoretical basis. As the first paper in the series of three, the main objective of this study is to justify the research by determining the significant problems...

This paper is the counterpart to the paper Collaborative Takt Time Planning of Non-Repetitive Work of Iris Tommelein. Both paper describe Takt approaches in two different geographical and project contexts. A follow up paper is planned and will compare the described approaches and assesses their applicability and success. This Paper describes the German Takt approach...
