Abstract

Being a developing country, the construction industry plays a pivotal role in Malaysians development. However, the fast phased industry may have overlooked some of its project management issues namely variation order during the construction stage which effected the project handing over and also increased in the construction cost. The research objective is to develop a prediction model to decrease variation order in residential projects in Malaysia.A total of ten (10) variables were analysed to test their impact on construction cost and time. Two regression models are developed using real data obtained from a project located in the state of Selangor, Malaysia. It was found that there are three independent variables were a significant positive impact on the effects of time and cost in the construction project. The variables are as follows: Scope of work changes by the owner, Changes of building materials and work methods by the owner and Specifications change by the owner. Besides, the prediction model for project cost and time have also validated the results.
