Almeida Prado, Travessa 2, no. Email: jpcintra usp. The application of a 3D laser scanning technology to the terrestrial survey of the water pipeline tunnel excavated in rock is presented. After identifying the place, we present the problem, which is the precise surveying of the tunnel to identify and collect data to quantify differences in the cross section of the tunnel with respect to the section provided in the project, for the correction of these defects. The main possible methods of survey, listing pros and cons of each one are summarized.

In the sequence are shown the basis of this survey technology as well as the methodology of fieldwork and office, including the calculation of the coordinates of the points of the tunnel. The paper ends with the quality control and evaluation of the method, indicating its strengths compared to other methodologies. Existe literatura internacional com diferentes enfoques: Seo et al.
