Abstract
Abstract The Bandung State Polytechnic (Polban) Student Dormitory, built in 1982, has been standing for over 40 years, nearing the building life expectancy recommended by the Ministry of Public Works and Housing (PUPR), which is 50 years. This condition has been exacerbated by the COVID-19 pandemic, which left the building vacant for three years, halting its maintenance. The student dormitory is an important facility but has not received adequate annual maintenance funding, resulting in various damages and non-functional facilities. This study investigates building damage using Terrestrial Laser Scanner (TLS) technology to create a 3D model aimed at expediting the investigation at the research site, which includes three dormitory buildings, each with 3 floors and 24 rooms. The investigation results indicate that the Polban Student Dormitory falls into the Moderate Damage category. Non-destructive tests, such as the Hammer Test, Ultrasonic Pulse Velocity (UPV), and Rebar Scanner, were conducted and processed using ETABS software to assess the condition of the building structure. The results showed that the Polban Student Dormitory has concrete with a column compressive strength of 28.42 MPa, beams at 25.2 MPa, and floor plates at 25.25 MPa, as well as reinforcement with U24 quality.
