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.
