Technical
Our Prefabricated Timber Construction SystemTM (PTCSTM) is more than just a suite of panels and members shipped to site and assembled in sequence, it’s a complete construction methodology comprising various kits of parts prefabricated off-site utilising a simple platform to deliver an entire construction system. Like car manufacturers who build on platforms called chassis’, the PTCSTM using a similar method of building commonly designed structures and adapting the system to meet the specific building physics requirements.
National Codes
The NCC 2019 extends the use of fire-protected timber systems in all classes of building. The ‘deemed-to-satisfy’ solution for timber construction requires the use of fire-protective coverings like fire-grade plasterboard on timber structural materials. The requirement for sprinkler systems in timber structures had previously affected their competitiveness with concrete and steel buildings, but the NCC 2019 includes compulsory sprinkler systems in all Class 2 and 3 buildings between four and eight storeys in height.
Standards & Compliance
Our products are produced under strict manufacturing guidelines and controls. A third-party independent certified Quality Control system is used for the manufacture of all engineered timber products as associated items.

Acoustics
Acoustic control in a mass timber building is critically important. Mass timber systems have a disadvantage in preventing lower-frequency sounds from transmitting through the structure. The good news is that there are plenty of solutions to prevent sound transmission. Sound is caused by vibrations which transmit through a medium and reach the ear or some other form of detecting device. Sound is measured in loudness (decibels (dB)) and frequency (Hertz (Hz)). Mass timber systems are particular good at eliminating higher-end frequencies.
Certification
CLTP Tasmania only sources product from sustainably managed plantations. The CLTP Tasmania Board, Executive and entire workforce have committed to support efforts to eliminate illegal logging through a commitment to relevant certification programs. The various certification frameworks verify that raw materials are obtained from sustainably-managed plantation forests. The scheme also ensures that sourcing of the raw materials is supported by an effective internal controls, like a quality control system. Finally, CLTP Tasmania must meet stringent criteria and conditions connected to external monitoring by third parties.
Quality Assurance
Our quality assurance framework has been designed to provide a robust and coordinated approach to quality. In doing so it makes reference to various Australian and International Standards; and examples of best practice within the mass timber products sector. The framework embraces a continuous quality improvement methodology. Our continuous quality improvement approach is integrated into the organisations strategic planning and risk management methodology and is aligned to the strategic and operational objectives of CLTP Tasmania.
