Underlying Causes, Effects and Mitigation Measures of Delays in Construction Projects

Delays in construction projects are identified as a worldwide issue as it has been addressed in many recent empirical studies. This paper aims to investigate the causes and effects of these delays and analyse whether these delays can be mitigated with a well-managed strategy. This study utilises a qualitative approach by first, conducting a critical review of the literature to analyse the causes and effects of construction delays. The study then conducts in-depth interviews with construction professionals to verify the industry’s position on this topic and to make recommendations about the mitigating measures. The interviewees sample represents a cross-section of the industry and its project roles. The key findings of a total of 12 interviews highlighted that ‘financial related effects’ are the most crucial ones that requires close scrutiny. Among the parties involved in a construction project, ‘client’ is in the highest risk of being penalized for these financial implications of delays. Although the contractor is generally required to try to prevent or mitigate delay, even where the fault is not their own, clients have the highest level of responsibility in delay-related decision making. However, depending on the procurement route this can vary. In terms of the causes ‘communication, coordination and planning’ reports as the highest contributor for to delays. The effects of these are mostly lost profit claims and delay and disruption claims. However, Building information modelling possesses a potential to mitigate the latter and. Nonetheless, the interviewees also highlight the need for training and awareness in above digital technology over traditional management practices, to perceive desired value.
