As-built drawing generation of LFM building ITB using terrestrial laser scanner

Abstract

Abstract The LFM ITB building, which was built in 1939, needs to be renovated in some or all parts of the building without removing the existing characteristics and philosophical values. Therefore, renovations must refer to the building’s as-built drawing documents. As-built drawings can be made using Terrestrial Laser Scanner technology. TLS technology will be the main component in making the three-dimensional model of the LFM Building which will later become a reference in making as-built drawings. The purpose of this study is making 3 dimension model and as-built drawing of LFM building from TLS data. In this research, Building LFM modeling uses data from measurements using TLS. Data is processed through a registration process to unify all data. The average value of registration errors is 0.006 meters. The noise removal process removes unused data. The modeling process is carried out to produce a solid model that represents the shape of the LFM Building in the field. The results of the three-dimensional model will be used as a reference in making as-built drawings that include floor plans, visualizations, and building pieces. The results of the registration are then validated by using a distometer for vertical distance and measuring tape for horizontal distance. Vertical distance validation has the largest value of 0.012 meters and horizontal distance has the largest value of 0.011 meters.
