Currently 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 because of its special nature, crucial time requirements and size. Many D&B projects ended in the hands of contractors lacking knowledge on the other major constraints of this procurement method. They are basically committed by judgement and inadequate experience and unable to execute the project within the agreed time and price. The risk is more while committing to multiple simultaneous projects. This paper is a part of the research involving seven (7) case studies on actual multiple D&B projects. Site visits and project documents provided the core data for the case studies. The characteristic background of each project is presented with contractor's, consultant's and owner's opinions. From the collected information, data on the factors influencing time and cost overruns were summarized. The researcher's opinions on each case study are provided in conclusions. © 2011 IEEE.
