Abstract
Conventionally, measurements of width, length, and height have been performed using tape measure and level in management of work done. Since 2016, the Ministry of Land, Infrastructure and Transport is working on i-Construction and aims to improve productivity. Among them, in April 2016 formulation management procedure (draft) (using pavement work) using a terrestrial laser scanner was announced, and it is expected that usage will increase in the future. Although the result could be measured with the accuracy according to the performance of the model, there were cases in which it was not possible to secure the assumed precision due to the malfunction of the equipment and the observation condition.
