This paper reports on an on-going action research study on waste in the structural design process (SDP). To understand the waste types and their effects, the lean tool, value stream mapping (VSM), has been deployed in the doctoral study.

This paper examines fundamental reasons for ethical dilemmas occurring in the context of value delivery in construction projects and provides a theoretical framework to form the basis for future empirical research on ethical issues related to value delivery to customers, broadly defined.

This study examined the presence of counterfeited, fraudulent and substandard (CFS) materials in the Norwegian construction industry and the characteristics of the construction industry that render it vulnerable. The interviewees believed that the industry is vulnerable because it is easily accessible for temporary and dishonest actors, and it has a high degree of trust combined...

To serve as support for this development, a tool called DOLC was created to analyze and assess the degree of Lean Construction of a construction company. Based on the 11 principles of Koskela (1992)...

As off-shore prefabrication continues to gain momentum, supply chain management becomes increasingly complex for industrial modular construction projects and delays commonly occur to prefabricated modules. In order to make efficient utilization of limited module assembly resources (e.g., crews and bays) and reduce the waiting waste of materials on the module yard, a systematic optimization approach...
