This paper presents a new construction management cooperated with clients using a parametric information design method for road construction. This management has been found to be efficient and accurate. This method aims for re-designing and for managing to achieve the conformance of the completed form of roads to planned design with survey equipment. By using this method, we design a road with an information model that has alignments, profile and cross sections. The model can be changed according to the site condition in collaboration with the planning designer of the client. This method is able to manage the conformance of completed form accurately because the information model is precise. Furthermore, the file size is so small that the survey equipment can store the data, and it is easy to re-design the plan. Therefore, we are able to use the survey equipment easily for the conformance management of completed form accurately and to re-design a plan by using CAD quickly. Keywords. con...
