Assessment of Construction Surveying Efficiency and Effectiveness for Locating Roadside Tree Using a Total Station, a handheld GPS, and a Low-cost Smartphone GPS Device

Abstract

In road construction, to collect coordinates of different objects It is one of the first processes in road construction. And it is important to the management of the construction time of the project because if the management of the survey process is good, efficient and not delayed, will result in other construction areas. The projects begin construction faster, increasing the chance of road construction to be completed before the contract expires. Therefore, choosing a method and appropriate equipment for surveying, it can be considered extremely important in road construction because it will make the cost, time and resources available. In this study, the efficacy was compared. And the effectiveness of data collection of coordinated trees, road construction. It will compare all 3 types of devices: Camera, Total Station (Total Station), GPS receiver and applications to find GPS coordinates on mobile phones, smartphones The results were consistent with the hypothesis, and suggested the findings of the conclusion.
