WHAT IS THE COMMERCIAL TIMBER GUIDEBOOK?
The aims of the Guidebook are as follows:
– To provide a consensus approach to design and construction of mass timber that assures the insurance industry of intended good practice. – Inform the design, development, and construction community to advance the use of mass timber. – To produce a guide to good practice risk mitigation for anyone engaged in mass timber construction.
The Commercial Timber Guidebook’s (CTG) main purpose is to address the insurance sector’s concerns about the risks associated with adopting mass timber in construction. The CTG represents a consensus of current good practices in the design of mass timber buildings and provides technical guidance for risk mitigation, and remediation strategies in relation to durability due to moisture, and fire. The Guidebook is not, and does not purport to be, a standard for mass timber construction and it does not intend to guarantee, to the user of the guidebook or its associates, the availability of insurance. The authors, contributors and funders recognise the importance of available, affordable and long-term sustainable insurance to the successful development and continued innovation of sustainable construction. The Guidebook is intended as a the beginning of an ongoing and developing dialogue with the insurance industry, its specialist advisers, and consultants in risk.
CHALLENGES OF INSURING MASS TIMBER BUILDINGS
Currently it is proving challenging to obtain sustainable property insurance for mass timber commercial buildings. The insurance sector acknowledges the requirement for an increase in the adoption of mass timber to meet sustainability goals, however there are a number of concerns regarding the safety and resilience of mass timber buildings. They seek assurance that these concerns are fully considered, and design measures are put in place so that risks are satisfactorily mitigated.
