“…A terrestrial laser scanner (TLS) as shown in Figure 1, is a type of surveying instrument that uses laser technology to capture highly accurate threedimensional (3D) data of a physical environment or object. TLS is commonly used in fields such as architecture, engineering, construction, and archaeology to create accurate 3D models of buildings, landscapes, and cultural heritage sites [4]. Emerging technologies are changing many industries by focusing on improving product quality, increasing production rates, and lowering long-term costs.…”

A bridge is a structure that joins two highways and has four distinct parts: the deck, abutment, pier, and joist. For safety reasons, this structure required routine inspections by a qualified inspector. Suggesting a new approach that uses non-contact testing technologies (NCT) will resolve all the difficulties related to the inspector’s current conventional method’s increased time, expense, and labor intensity. Compared to traditional approaches using visual inspection, NCT technologies are prospective instruments for assessing the state of bridges since they allow for quick and simple measurement with little disruption to traffic. Terrestrial Laser Scanner (TLS) is now taught in surveying courses to help surveyors perform their jobs more efficiently. The goal of this study was to make technology use better because it requires less human interaction with quality results. TLS contains a points cloud consisting of x, y, and z coordinates; hence it can produce 3-dimensional (3D) model output. The main objective of this study is to produce the 3D model from point cloud data, followed by the second objective, which is to compare measurement of pier dimension with various distance of TLS setup distance location. To achieve this objective, configuration of TLS with Zig Zag setup location to cover all of bridge structure to produce a 3D model and configure three various distance TLS setup location to measure the accuracy of pier dimension. The control actual data was done by measuring using Total Station and measuring tape. The output of point cloud data from TLS using Cyclone Register360 was compared with actual data. The results shown point cloud data from TLS can produced 3D model with accurate dimension measurement. Setup the TLS location depends on the suitability of the work to increase the quality of data.
