Abstract:
Value Management (VM) and Environmental Sustainability (ES) are increasingly
becoming important tools to be considered in construction. VM is one of the recognized techniques that made substantial cost savings on construction projects and sustainability is about delivering better long term value for the built environment and its inhabitants. The attention on ES issues in VM remains untapped area due to scarcity of information. Theoretically, the intrinsic capabilities and the positive relationships between these two heighten VM position as an effective means for sustainability improvements. The purpose of this research study is to identify how the ES criteria could be incorporated into the VM process and it's acceptability by the construction clients. The research is focused on a development of a process model by combining both ES and the best value criteria to select construction materials.
The research was placed in qualitative research philosophies as the aim was to generate rich data from the experiences of VM team to find the means of ES delivery in VM. This -research begins from the data gathered through a comprehensive literature review and unstructured interviews. Based on the literature review the Integrated Process Model (IPM) was developed. The developed model was tested through multiple case studies to find the client's acceptance towards the environment favourable material selection.
It was found 47% of materials derived from the IPM are purely matching with the client's choice. By adopting this process model at the very early stages of material selection the acceptance can be improved further.
The research can concluded that the VM and ES can be incorporated through the
Integrated Process Model to select construction materials. Further the model has the high level of acceptance among the construction clients and the early application of the model provides multiple benefits to the project stakeholders.
