Modelling the service life of wood in ground contact – Verification of remotely sensed soil data from the reanalysis dataset ERA5-Land using in-situ measurements at a test site of utility poles in Eastern Norway
2024 - IRG/WP 24-41003
This study compared soil moisture and temperature estimates from the 5th European reanalysis (ERA5-Land) dataset with in-situ measurements to assess the accuracy and applicability of ERA5-Land data for modelling the service life of wood in ground contact. The ERA5-Land soil temperature estimates showed a moderate correlation with the in-situ temperature measurements (Spearman’s ρ of 0.73) and a...

Assessment of historical pilings from Lisbon
2024 - IRG/WP 24-41004
The renovation and rebuilding of areas in Lisbon has led to work on buildings constructed in the Pombaline downtown district. These buildings were constructed on wooden pilings, as a means of stabilising unstable soils and transfer the loads from buildings to soils with adequate bearing capacity. These methods also increased the resilience of the reconstruction works to future possible earthquakes...

The durability and mechanical properties of 40 years old Black locust poles
2024 - IRG/WP 24-11042
This study investigates the durability and mechanical properties of 40-year-old black locust (Robinia pseudoacacia) poles harvested from a vineyard in Slovenia. Wood from these poles was compared to recently harvested black locust wood to determine possible reuse options. Visual inspection, hyperspectral imaging, and laboratory tests were conducted to assess decay, density, mechanical properties, ...

Transmission poles - Analysis of causes of premature failure in Slovenia
2025 - IRG/WP 25-20745
The study focuses on analysing the causes of the premature collapse of wooden transmission poles in Slovenia, where there have been several cases of rapid fungal decomposition of poles despite the planned lifespan of 30 to 50 years. The poles were made of Scots pine wood and impregnated with a copper-ethanolamine wood preservative. The research aimed to assess the condition of standing poles and e...

mpact of Fence Post Footings on Wood Post Durability
2025 - IRG/WP 25-41025
Residential wood fence posts may be dug directly into the ground, secured to a metal spike that goes into the ground, or secured to a concrete footing with a metal boot. It was hypothesised that by keeping wood posts out of the ground both spikes and boot attachments would increase protection against decay and termites and extend the service life of the post. After 9-years of exposure in Kincardin...
