Procedimentos para a composição das peças técnicas para a regularização de imóvel urbano

Abstract

The purpose of this work was to describe the procedures necessary to carry out the technical parts for the regularization of an urban property in accordance with NBR 17.047/2022 and NBR 13.133/2021. Before starting the topographic survey, the coordinates of 2 (two) points were determined in the Universal Transverse Mercator (UTM) system in the SIRGAS 2000 reference system, to orient the topographic polygon. The positioning method used was Precise Point Positioning (PPP) using a pair of CHC brand GNSS receivers, model I80, with a tracking rate of 5s (five seconds), elevation mask of 10° (ten degrees) and minimum occupation time of 2h (two hours). The topographic survey was carried out using a Ruide Total Station (TS) model RTS 822R 3 , with angular accuracy of 2” (two seconds) and linear accuracy of ±(2mm + 2ppm). The polygonal survey was carried out by walking with irradiation, with the first station and reverse station performed at points with known coordinates. The polygonal survey was composed of 4 vertices and 96 irradiations, with curbstones, posts, walls, trees, manholes, manholes, central flowerbeds, lot frontages, traffic lights and bus stops being registered. The polygonal survey was classified as secondary according to NBR13.133, with an angular tolerance (TA) of 40” (forty seconds) and a linear tolerance of 1/12000. The angular error was 0° 00’ 32” and a linear error of 1 cm, providing a linear accuracy of 1/12135. The propagation of the standard deviation was performed using the simplified model presented in NBR13.133/21 and was less than 8 (eight) centimeters at all points of the polygon or vertex of the property. The technical documents descriptive memorial, topographic plan, technical report and term of responsibility will serve as support for the regularization process of the property.
