What is Mass Engineered Timber

what_is_clt

Cross Laminated Timber (CLT) is an engineered structural material comprising layers of wood stacked cross-wise and bonded with structural adhesives. CLT is used for walls, floors and roofs.

Glued Laminated Timber (Glulam) is produced in a similar fashion but with the grain aligned in one direction. Glulam is predominantly used for structural beams. Both are prefabricated in factories to precise specifications, then joined on-site with simple connections using hand tools to form complete structures.


What are the Benefits of Using MET?

To raise construction productivity and fundamentally change the design and construction processes, BCA encourage the industry to embrace the concept of Design for Manufacturing and Assembly (DfMA), where construction is designed such that as much work may be done off-site in a controlled manufacturing environment as possible. MET is a game changing technology that support the DfMA concept to significantly speed up construction.

They can potentially achieve a productivity improvement of up to 25% in terms of manpower and time savings, depending on the complexity of the projects. MET needs minimal on-site manpower as timber members are prefabricated offsite and joined on-site with simple connections using hand tools. Furthermore, dust and noise pollution can be minimised as more activities are done off-site.


Requirements for MET

MET has been granted In-Principle Acceptance (IPA) by the Building and Innovation Panel (BIP). Companies which are interested to supply or adopt MET in local construction projects would not need to apply to the BIP for evaluation. Instead, they should comply with the IPAs issued to the firm CLT Builders shown below.
