Project Conveyance Strategies Change Request types and Extents Experienced in Expressway Development

Abstract

Transportation authorities might have a problem with construction modification orders and the rise in costs that come with them. Practitioners and academics alike are interested in discussing this topic. Because of the difficulties involved in resolving this issue, the management of modification orders in alternate delivery methods is even more important. Change orders and project delivery techniques are rarely studied together. despite the fact that this issue is significant. This study demonstrated a connection between delivery methods and highway construction modification orders. This study only includes the kinds of change orders that have been studied in the business and literature. Data from 162 US road projects completed between 2004 and 2015 were included in the study. Interviews with representatives of the many organizations involved in the various initiatives studied complemented the quantitative data. According to the data, agency-directed modification orders are followed by unanticipated conditions in increasing overall costs. There was evidence that owner agencies frequently added value through agency-directed modification orders when they took advantage of an initial contract excess, which is more prevalent in design-build delivery. The findings of this study may assist agencies and researchers in developing efficient mitigation strategies and gaining a deeper comprehension of the factors that lead to change orders in various delivery systems
