MASS TIMBER BACKGROUND
THE GUIDEBOOK STRUCTURE
Insurance This chapter provides context for mass timber buildings from the perspective of the insurance sector along with a summary of current risk guidance documents and where both the construction and insurance sectors have been able to learn from experience when designing mass timber buildings. Timber Offices This chapter provides a general overview of timber office buildings. The chapter discusses the types of engineered timber that are commonly used in mass timber buildings and outlines architectural and structural considerations that influence the design of large office buildings.
The Guidebook is aimed at and will solely focus on commercial (office) buildings where mass timber construction is used, to demonstrate to insurers good practice design and risk mitigation guidance. It is not expected that the whole of the Guidebook will be relevant to all parties due to differences in expertise. The Guidebook is separated into three parts, Mass Timber Background, Technical Guidance and Example Building Typologies.
TECHNICAL GUIDANCE
T IMBER OF F I CES
I NSURANCE
The technical design guidance forms the majority of the guidebook and is written primarily for designers. The scope of the CTG has aimed to cover relevant information for mass timber buildings to address the significant risk areas for mass timber buildings. Durability This chapter focuses on how mass timber’s durability is affected by moisture, outlining the risks associated with water damage and providing strategies for mitigating these risks to create robust, durable buildings.
F I RE
DURABILITY
This includes technical guidance on:
– The properties of timber relating to moisture and durability and specifying appropriate materials. – Highlighting key risk areas and how these can be mitigated in the design phase, construction phase, and in use phase. – Guidance on the remediation process if mass timber is damaged by water. – A set of durability principles that can be adopted by designers to demonstrate good practice relating to identification of risks, risk mitigation measures and remediation strategy.
