Continuous improvement cells in the highways sector


In line with its performance improvement and Lean Construction agenda, the highways supply chain in the UK has commenced many Continuous Improvement (CI) cells in recent years. The CI cell is a small-group work coordination and improvement technique that is frequently used in many industries as part of their lean transformations. The technique has also...

Why visual management?


Visual management (VM) is argued to provide a more rapid and reliable mode of communication in comparison to traditional alternatives. VM is thus compatible with the lean tenets of time compression and variability reduction.

Tolerance compliance measurement using terrestrial laser scanner


Terrestrial laser scanning (TLS) provides remote sensing and a quick and comprehensive technique for deviation analyses. Its application for precision surveying purposes is becoming a common practice. There are many interdependent parameters that determine whether the accuracy obtained during the data collection and registration is appropriate to perform deviation analyses. Also, the accuracy of deviation...

Building shared understanding during early design


Early Design Collaboration in construction projects can be hampered by misunderstandings between team members. Consequently, design actions are not supported by all, causing delays and frustration. This paper presents a study aiming to capture (a) misunderstandings between participants at early design stages, and (b) how these individuals resolved such misunderstandings through shared understanding. An exploratory...

Using design science research and action research to bridge the gap between theory and practice in lean construction research


The descriptive approaches, like case study, interview, survey, observation and document analysis, widely used by the lean construction community to investigate managerial problems in the construction industry, typically provide explanations of problems and not solutions to them, leaving a gap between theory and practice. Two prescriptive approaches-design science research and action research-are therefore recommended.
