Wood Utility Pole Inspection and Life Extension
Proper maintenance of wood poles, which includes inspection and application of remedial treatments, helps add many years of safe, reliable service life to your pole plant, thereby reducing unnecessary or premature replacement costs.
Osmose pole inspection programs allow you to better manage the critical factors that determine pole performance – strength, load, and cost.
The keys to a successful wood utility pole inspection program are:
- Identifying decay & measuring defects
- Estimating the pole’s remaining strength to determine pass/fail - Inaccurate strength calculations can be costly. A false fail can lead to unnecessary spending on restoration or replacement, while a false pass can create risk that may lead to pole failures and costly damage and repairs. Osmose technicians use StrengthCalc® software which models the cross section of decaying poles in relation to the transverse loads. StrengthCalc accounts for both the severity and location of the decay with respect to conductors and equipment. StrengthCalc determines precise section modulus to provide the percent remaining strength for weakened poles.
- Applying effective remedial treatments to extend the safe, reliable service-life of the pole. Remedial treatment is the key to getting the most out of your investment. The use of remedial treatments will earn dividends via extended pole life and improved plant resiliency.
Methods & Accuracy of Wood Utility Pole Inspections
The primary purpose of a power pole inspection is to assess wood condition as accurately as possible. Methods vary according to the degree of wood decay and damage.
- Sound and Selective Bore: Poles are "sounded" with a hammer to detect internal decay. Poles that show signs of internal decay (based on the sound test) are bored to determine the location and extent of the decay.
- Sound & Bore: Poles are "sounded" with a hammer to detect internal decay and poles are bored to determine the location and extent of the decay.
- Sound & Bore with Partial Excavation & Selective Treatment: Poles are "sounded" with a hammer to detect internal decay and bored to determine the location and extent of decay. Poles that show signs of internal or external decay are fully excavated to a depth of 18" to determine the extent of decay at the groundline. Decayed wood is removed and a preservative paste is applied to protect the remaining sound wood.
- Industry Best Practice: Comprehensive Life Extension (sound, bore, 18" excavation, remedial treatment). Poles are "sounded" with a hammer to detect internal decay and bored to determine the location and extent of decay. Each pole is fully excavated to a depth of 18" to determine the extent of decay at the groundline. Decayed wood is removed and a preservative paste is applied to protect the remaining sound wood.
