OPTIMISING VALUE DURING CONSTRUCTION SCHEDULE ACCELERATION

Construction Schedule Acceleration (CSA) can affect not just the time but many other project aspects. During a CSA, there can be many impacts having significant effects on the project value. Previous studies have highlighted the importance of considering quality, productivity and functionality at a CSA along with cost and time. The aim of this research is, therefore, to investigate how value can be optimised during a CSA process. A qualitative research approach was adopted. Altogether, ten semi-structured interviews were conducted. The interview data were transcribed and analysed using a manually performed content analysis. This study has revealed types of CSA based on the purpose (delay minimising purpose or non-delay minimising purpose) and the party who initiates it. Cost, quality, functionality, productivity and profitability were identified as main value considerations during a CSA other than time. Applicability of value management (VM) job plan stages and Earned Value Management (EVM) indicators during different CSA stages to optimise value were also found. Finally, these findings were mapped in a framework to show how VM and EVM concepts could be used in enhancing value during a CSA. The framework conceptualises the relationship between “value” and CSA and how it varies upon distinct parties of a construction project during different stages and types of CSA. The proposed framework can be used as a guidance for optimising the value during the stages of a CSA.
