Abstract

This paper is focusing on determining the capability of reflector-less total station in monitoring building's deformation as well as to check the deformation of Universiti Teknologi Petronas (UTP) Academic Complex canopy system. Monitoring building deformation is an essential practice in order to determine whether the structure is within a safe behavior or not. There are numerous methods to be used such as the application of close-range photogrammetric, application of fiber optics, application of LiDAR technologies as well as geotechnical method (inclinometer, accelerometer, and tiltmeter). However, there are certain limitation and constrain faced by the mentioned methods in order to perform deformation monitoring at the building edges and critical area. Therefore, this project is to check the capabilities of reflector-less total station (R TS) in monitoring deformation of structure as well as the accuracies of the data obtained by performing a field data measurement. Topcon GPT 7501 series is used in this field data measurement for monitoring the deformation of canopy system situated in front of building 13 and building 14, UTP academic complex with 4 observation points. The spatial data coordinate obtained in the first reading will be used as a base data for subtracting with the following continuous reading performed. Total displacement recorded based on field data measurement shows the maximum movement is 1.61 mm towards the structural beam on column 3 and 4 in front of building 14, Universiti Teknologi Petronas. Even though the result of monitoring displacement up to millimeter movement has been achieved, the result is insignificant as the movement recorded is not within the boundary of the capability reflector-less total station as the accuracy of the instrument is ±5 mm in its non-prism mode. Therefore the displacement or movement does not occur as after subtraction being done, the movement is below ±5 mm accuracy of the equipment. However, based on the field data measurement conducted, the overall objective of this project has been achieved for checking the capability of reflector-less total station in monitoring deformation.
