The application of UAV and CSP1 matrix for building inspection at mosques in area of Pagoh – Muar, Johor

Carrying out building inspection is very essential when it comes to conserving the condition of a building. The aim of performing building inspection on Pekan Pagoh mosque, Pekan Panchor mosque and Sultan Alaudin Riayat Syah l mosque is to evaluate their condition using Condition Survey Protocol l (CSPl) method. Condition Survey Protocol (CSPl) is used as an evaluation apparatus as it is appropriate for various structures to classify the data based on its condition and destruction evaluations. CSPl Matrix has also been developed in order to reduce the process of interpreting the data which would then support shortening on-site inspection time. It would be difficult to determine a building existing condition without suitable inspection and that would result a possible failure of the building in the coming years. Therefore, an UAV is used to aid in the visual inspection and CSPl Matrix is used to analyze the condition of all three mosques and identify the seriousness of each defect detected. Thus, the total score for all mosques were calculated whereby for Pekan Panchor mosque, the score is 3.4, 2.9 for Pekan Pagoh mosque and 4.l for Sultan Alaudin Riayat Syah l mosqu.
