In bridge inspection practices, what should be monitored on timber decks specifically?

Monitoring environmental decay and insect damage on timber decks is crucial because timber is susceptible to various forms of deterioration due to environmental conditions and biological factors. Factors such as moisture can lead to rot and decay, significantly compromising the structural integrity of the deck. Additionally, insects like termites and wood borers can damage timber, leading to structural failures if not addressed promptly. Identifying these issues during inspections allows for timely maintenance and repairs, which is essential for ensuring the safety and longevity of the bridge. Regular monitoring helps in implementing preventive measures and upholding the overall performance of timber deck bridges.
