Case study and survey on time and cost overrun of multiple D&B projects
Current trend of Design and Build (D&B) has gained popularity in the construction Industry due to its attractive financial aspects. The development projects are implemented by D&B for its special nature, crucial time and size. Many of this D&B projects had ended in the hands of contractors unable to proceed the projects within agreed time and price. Even some of those completed projects were committed to begin implementation without carrying any analyze of risks involved. They are basically committed by judgement and inadequate experience. The risk of time and cost overrun is more while committing to multiple simultaneous projects. Even though there were studies conducted for Risk management of projects and studies on contractors' view of D&B projects, so far there are no studies conducted on time and cost risks of D&B projects. In addition to study further for multiple projects. The aim of this study is to identify elements and procedures to analyse and overcome the risks of the important components of time and cost in management of multiple D&B bridge projects. The research has dual approach by conducting questionnaire survey and multiple case studies for the analysis and findings. This will encourage the industrial practitioners to prepare a practical risk response plan to complete the projects successfully. © 2011 IEEE.
