Moisture Management During Construction

During the construction process, it is likely that timber will be exposed to significantly higher levels of water and moisture than in its final, designed state. These higher levels of water and moisture exposure can lead to staining, mould, dimensional movement, and fungal decay. With the right design decisions, planning and management, these negative effects can be avoided. If adequate measures are not taken, very significant problems can result. This guidance document summarises the key background principles of moisture damage to timber, introduces the principles of a Construction Stage Moisture Control Plan (CSMCP). It explains the risk-analysis process and mitigations available to designers and contractors and the importance of rigorous monitoring and records on the job site.
