This study promotes the Sustainable Development Goal (SDG) 9, which focuses on building resilient infrastructure, promoting inclusive and sustainable industrialization, and fostering innovation. By using Non-Destructive Testing (NDT) techniques, particularly Portable Ultrasonic Non-Destructive Indicator Testing (PUNDIT), the study promotes the assessment and maintenance of materials without causing damage. For this study, PUNDIT is used to evaluate the effect of pulse velocity on two selected Malaysian tropical timber species, i.e. Bintangor and Yellow Meranti. This research is concentrated on assessing the relationship between timber lengths and pulse velocity parallel to the grain directions. Forty (40) readings of pulse velocity was measured for each species using a series of length in increment of 215 mm distance of each. The readings were measured using direct transmission method. From the experimental laboratory test, the result indicates that there was a weak correlation between the timber length and pulse velocity. The relation was found insignificant since the r-squared of the pulse velocity to the timber length was 24% and 16% for the Bintangor and Yellow Meranti, respectively. The inconsistent pulse velocity is likely related to the strength group, density, moisture content and unforeseen defects inside the specimens. In conclusion, it is found that utilising the PUNDIT pulse velocity to measure the length of Bintangor and Yellow Meranti timber is inappropriate. It is proposed that for the upcoming test, a distinct density range between the chosen species be considered. The result shared in this research evaluated the quality of timber species contributes to the construction of buildings and structures that are safe and durable, aligning with the goal of developing resilient infrastructure, as specified in the SDG 9 respectively.
