Industry perceptions of mass engineered timber (met) construction: A comparison of South-East Asia with other regions

Mass Engineered Timber (MET) has emerged as an innovative construction material used in the creation of low-carbon buildings. However, more built examples are found in Europe and North America, with far fewer in Asia, despite its generally higher levels of construction. This research explores these trends by measuring building industry practitioners’ perceptions–their awareness, attitudes and perceived obstacles–across three regions experiencing different levels of MET adoption: Europe and North America (early adopters), Australia and New Zealand (early developing) and South-East Asia (under developed). The research develops a novel framework to understand industry perceptions of MET composed of ‘Enabling Parameters’ and ‘Decision-making Parameters’. This is used to develop a survey which was completed by 186 participants from the three regions. Results show that participants’ perceptions, knowledge and experience of MET are consistently lower in South-East Asia, than the other regions–a finding previously not identified in existing research. Protection against fire and water damage, ease of repair and maintenance, and perceived unsuitability of MET for high-rise building types are the primary concerns of practitioners in South-East Asia. This paper calls for technological advancements for taller MET and hybrid buildings, a review of building codes, provision of incentives, and education among practitioners to improve the perception and adoption of MET in South-East Asia.
