Abstract

In the road construction, the road data collection survey is one of the initial processes and is an essential component for the project time management. If the management of the survey process is well-organized, efficient and not delayed, it will result in other construction processes as the projects will begin construction earlier and will increase the chance of project completion before the contract expires. Therefore, the choosing of method and appropriate survey equipment would be the key success of road construction project because it will consume the costs, time and resources efficiently. This study will reveal the comparison of effectiveness and the performance of data collection survey of trees’ coordinates which inferred as road obstacle by comparing 3 types of devices, including TOTAL STATION camera, GPS receiver, and applications to locate GPS coordinates on smartphones. The result indicates that each tool is suitable for data collection surveys depending on the key purpose. For the limited time purpose, we should use a portable GPS. But if we would like to save the project costs, we had better select a smartphone because of a lower cost per day and the similar accuracy.
