Abstract:
A Variation Order is any deviation from the first extent of work that is given by the task proprietor to change the project scope to boost benefits and achieve objectives. The majority of these variation orders are unavoidable. Conventional contract change practice typically involves a variety of paper documents and two-dimensional drawings that are unable to effectively depict altered construction conditions. Misunderstanding and inadequate communication among project stakeholders are frequently the results of this. Evaluation of cost and timetable effects is frequently emotional and unsystematic and adds to development questions. Building Data Displaying (BIM) is broadly utilized in current development projects. Building Information Management (BIM) is a promising tool that can address the aforementioned issues. The three main effects of a change order are evaluated in this study to see how BIM can be used to systematically analyze them: timetable, cost and bill of amounts. Through 3D BIM models, the BIM-integrated system enables users to systematically track and visualize the effect of a change order on building conditions. The system can also look at how a change order affects the project's cost and schedule. It presents another worldview of postponement and cost examination by limiting subjectivity and giving change request review trails.
