Wood Pole Lifecycle Data


You may be concerned that your wood utility poles represent an aging infrastructure risk. Osmose has compiled data from more than 750,000 poles across the United States to illustrate typical results from inspection and treatment programs. As you might expect, comprehensive maintenance helps poles to survive for many additional years beyond those that are run to failure.

The map illustrates Decay Hazard Risk (published by the American Wood Preservers Association) with #1 corresponding to the lowest risk and #5 to the highest risk for decay.

Lifecycle Map

Expectations for wood pole lifecycles vary based, in part, on decay hazard. Species and quality of the wood and the initial treatment help to determine lifecycles.

Decay Hazard Zone 1 - Initial Inspection versus Osmose Recycle Data  

 

Decay Hazard Zone 1

Using the Iowa survivor curve method, the predicted average service life without maintenance is 49.8 years.

The reject rates with maintenance are so low that a predicted service life can not be computed but would project to be greater than 100 years.

 

Decay Hazard Zone 2 - Initial Inspection versus Osmose Recycle Data  

 

Decay Hazard Zone 2

Using the Iowa survivor curve method, the predicted average service life without maintenance is 56.8 years.

The reject rates with maintenance are so low that a predicted service life can not be computed but would project to be greater than 100 years.

 

Decay Hazard Zone 3 - Initial Inspection versus Osmose Recycle Data  

 

Decay Hazard Zone 3

Using the Iowa survivor curve method, the predicted average service life without maintenance is 44.5 years.

The reject rates with maintenance are so low that a predicted service life can not be computed but would project to be greater than 100 years.

 

Decay Hazard Zone 4 - Initial Inspection versus Osmose Recycle Data  

 

Decay Hazard Zone 4

Using the Iowa survivor curve method, the predicted average service life without maintenance is 43 years.

The reject rates with maintenance are so low that a predicted service life can not be computed but would project to be greater than 100 years.


Decay Hazard Zone 5 - Initial Inspection versus Osmose Recycle Data

 

Decay Hazard Zone 5 

Using the Iowa survivor curve method, the predicted average service life without maintenance is 40.3 years.

The reject rates with maintenance are so low that a predicted service life can not be computed but would project to be greater than 100 years.
