Abstract

Change orders are among the main sources of problems challenging timely completion of construction projects. The significantly needed conducive interaction among project participants to mitigate completion delay risk due to change orders is often hampered by interface problems. This article describes potential sources of interface problems and their role in affecting completion time of change order-challenged infrastructure construction projects in Indonesia. The identified sources then serve as inputs to formulate a systems thinking model of relational interface problems in change order-challenged projects. A survey of eleven important infrastructure construction projects was conducted to obtain data on the main sources of these interface problems and their severity indexes. A second survey was later conducted to perceive the most frequent causes of change orders, the influence of interface problem cause factors on the length of change order process and the influence of interface problem cause factors on the expediting capacity of a project team and ultimately induce a delay of project completion. The results of both surveys then served as inputs to a systems thinking structure showing the factors in a change order-challenged project. The study shows that contract, technical experience, management, coordination and financial aspects are the potential sources of interface problems in Indonesian infrastructure construction projects. In a change order-challenged project, these interface problems' sources will complicate the efforts to achieve the project's time objective. The study especially points out the role of contract documents' quality in increasing the likelihood and extent of change orders and the influence of workers' productivity in mitigating the negative impact of a change order.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
