Introduction
Success of any project depends upon how best the activities are managed from conception till completion. There are various steps which add to in overall completion of the project viz. timely decision, timely approval of design, & drawings and financial management. There is a saying that “stitch in time saves nine.” In case of bridges also final completion depends upon how best the critical issues/are managed/ decided during the process of construction. To get the project completed in time most important point is selection of right contractor for executing the work, pragmatic time schedule and efficient management of the contract. All the bottlenecks be attended to as a joint effort of the project. The management should be fully conversant with the growth of activities in a bridge project in advance. Various aspects for effective construction management of bridge activities have been discussed in this paper.
