Thanks for your question Mr.Edy. The activity that has potential risk of failure or
being delayed is Box Girder Delivery. The first activity is predecessor for the next
activities since each activities has relation of ^Finish to Start^. It means, when the
first activity is delayed, it will affect other activities after it.

Thanks again for your question, Mr. Edy .

First of all, our research objective is actually to identify the 13 activities by
comparing statement method from three projects and then obtaining the expert
judgement and elected respondent. In the other hand, to answer your question, we
need a further research to discuss about safety plan and other. However, according
to our review the riskiest activity is erection it self or ^hanging up segment^ since it
can cause a catastrophic accident.
