The value of a product or service is recognized according to the appropriateness level of its performance and cost. It can almost truthfully be said that, by this definition, value can be increased by either increasing the performance or decreasing the cost. While a product is considered to have insignificant value if it lacks either appropriate performance or cost. Therefore, technological factors which has impact on the performance and cost of products or services in construction should be considered in their identification to gain optimum value. The objective of this paper is to assess the value of Slip Forming (SF) technology using value engineering by investigating its performance, cost, constructability, and productivity in construction projects that are matching modern construction technology. SF is one of these new techniques that have improved itself in the construction industry for decades around the world. The basic concept and approach of Value Engineering (VE) is implemented in this paper for achieve its objective. VE is a methodology used to analyze the function of the goods and services to obtain the required functions of the user at the lowest total cost without reducing the necessary quality or performance. The approach VE implemented is concerned with function improvement, time reduction, and improving performance through lesser consumption of energy, as well as cost reduction. VE technique provides us with a systematic approach taking in its account the design and construction projects, not making cost cutting while maintaining or improving the value. The application of VE principles causes people to work better as a team, searching always to improve their system of production and services. It helps any organization to improve and investigate its resources by optimizing costs
