Inspection Program

Détails d'un programme d'inspection

¨The details of an Inspection Program are covered in another training module¨

The main items related to it are;

  • Visual inspection
  • Inventory
  • Coring to determine rot
  • GPS Positioning
  • Structural Calculation
  • Treatment if required


The notion of inspection and treatment of woodden poles really took off in the 1990s in the United States, where utilities and telephone companies have put in place a general maintenance program for their poles.

The benefits of such a program are many, here are a few;

There are mainly monetary benefits, which allow to postpone for 10 years investments originally planned to replace poles at the end of their useful life, this results in very significant savings if we consider that the average replacement cost of a distribution pole ranges from $ 2,200.00 to $ 3,500.00 per unit.

  • We only replace poles that are really changing
  • There is therefore a real reduction in the risk of accidents
  • There is a reduction in involuntary power cuts
  • And finally every retired pole saves a tree

Pourquoi ?

The wooden poles being made of organic materials, are subject to possible deterioration. To delay this problem, the pole manufacturers applied initial factory treatment. The chemicals thus introduced into the wood fade more or less rapidly over time and according to the region of installation.

In fact, the more humid the installation area is, the longer the initial treatment will be, for example in Florida where there is a long period of sunshine and frequent rain showers, the average useful life of a pole is under 20 years old, the opposite in Arizona where it’s almost dry all year long , the same useful life is greater than 70 years. In Quebec, it is reasonable to consider their useful life from 30 to 35 years.

Treatment with paste, solid stick or liquid chemicals eliminates the internal moisture that has formed in the column. This moisture, if not treated, will cause neither more nor less of the rot and possibly internal voids, thus obliging the replacement of the pole.

This is the postponement of the replacement costs of 10 years, which is the main success of this new pole park management mode.
