At once, design additional fee is raised, but design additional fee estimation methods of domestic are not objectively and confidently. Therefore, this study proposed the estimation method that distributes the ratio in detail activity of qualified architect work scope and calculates the design additional cost by multiplying full design cost and the ratio. The estimation method applied to K project and confirmed the estimated design additional fee to be within negotiation of real case. However this study needs the more case study and actual and objective activity ratio. Eventually, this study expects that the owner easily utilizes and applies the estimation method. |
