Project understanding, planning, flexibility of management action and construction time performance: two Australian case studies

Construction time performance (CTP) and flexibility in approaches to project time planning have been shown to be significantly associated. This raises interesting questions about how effective planning and control to facilitate flexibility in overcoming unexpected problems may be achieved. Case study data were used to explore links between planning and flexibility. This paper reports upon a recent study of two highly complex projects, a mental and forensic health hospital and a very large freeway/bridge/tunnel urban infrastructure project. The authors investigated planning flexibility using a framework of project team understanding and knowledge transfer to provide a model that contributes to our understanding of mechanisms and drivers that delivers flexible behaviour that may affect CTP. We conclude that both ability, supported by organizational and team competence, and commitment to explore construction method options in a flexible manner, i.e. responding to unanticipated problems, are necessary to facilitate good construction time performance.
