Abstract: Propelled by various environmental movements, wood is expected to take over concrete and steel in the construction industry. However, wood has to be engineered to improve its properties like strength and fire resistance. Mass Engineered Timber (MET) such as Glued Laminated Timber (Glulam) and Cross Laminated Timber (CLT) has shown exceptional performance as a building material in various overseas projects. Singapore has also recognized the benefits that MET brings forth. The Zero Energy Singapore Sustainability Academy and The Wave at Nanyang Technological University (NTU) have employed this new building material and proven its capabilities locally. However, there is a heavy reliance on European softwood such as Spruce for engineered wood products. Surrounded by vast forested area, Singapore should look into the possibility of utilizing tropical wood for MET. Sengon, White Jabon, Acacia, Red Jabon and Bamboo are potential tropical wood species for engineered wood products. This paper seeks to evaluate the feasibility of using the selected tropical wood species in CLT for building construction in Singapore. Findings from the four-point bending test indicated that the characteristic flexural strength and mean density of Acacia and Bamboo are higher than Spruce which qualifies for C24 and GL 24h. On the other hand, Sengon did not manage to satisfy these requirements. Both White Jabon and Red Jabon showed comparable characteristic flexural strength with Spruce but they fall short in terms of its mean density. In the graveyard test conducted, it was concluded that the vulnerability of selected tropical wood species to termite/microorganisms infestation can be reduced by cedar oil treatment. However, the effectiveness of Termimesh in reducing vulnerability has to be analysed further. Additionally, none of the selected tropical wood species are naturally termite/microorganisms resistance.
