MODELING TO REDUCE VARIATION ORDER IN CONSTRUCTION PROJECTS IN EGYPT

Omar M. Fadl, Ayman H. Nassar

Abstract: Variation order is common phenomena in the construction field all over the world. These phenomena usually happen during any construction project which leads to dispute between the parties which are involved in the construction project. Also, the construction field is one of the main creations of any nation’s wealth as it is the backbone of most industries for developing economics. Variation in many cases causes problems and disputes among the parties which are involved in construction projects. Thus, it is very important to study the main causes of variation order and to figure out and control variation. As if no agreement is reached between the parties of the project, it turns into a claim and dispute that may negatively affect the progress of the project and reduce its ability to be successfully completed in time within the project budget. Variation order is mainly caused due to unavailability of equipment, poor workmanship, design complexity and changing project scope etc. Variation order mainly effects on increasing project cost and delay in completion time. The aim of this research is to produce a software modeling to help in reducing vary of variation orders causes and effects in construction projects. So, modeling eases the job and helps reducing the troubles that come along and solving problems. Modeling in the construction engineering field will act like a simulator which will help in solving that kind of variations that might be found in the construction projects. This model will act as a tool, which can show how to avoid variation or how to solve variation to minimizing the variation order causes in the construction field. As a fact variation order is unwanted as if we dream to have the construction field free of variations, but it is impossible to have a construction field free from variation order in reality, but it can be developing tools to assist in reduce and solve variations and this was the main aim of this research.
