Steel & Concrete Pole Assessment

Osmose steel and concrete inspection programs identify and assess deterioration on steel structures to prioritize those in need of repair and corrosion mitigation, helping utilities avoid future, costly replacements.

While steel remains an excellent choice for utility poles, it tends to degrade over time due to corrosion and mechanical damage. It is recommended to conduct an assessment of steel structures at regular intervals. An expert corrosion inspector is equipped to look into age, other structure characteristics, and environmental conditions and then identify areas of concern.

Comprehensive Inspections vs. Predictive Assessments

Steel assessment and concrete life cycle assessment can be divided into two techniques:

During a comprehensive assessment, Osmose crews evaluate each structure at grade by excavation to a depth of 18 inches. The area of the structure at grade, whether steel or concrete, is cleaned of contaminants, and degradation is measured and quantified to determine a structural condition rating. After the structure condition is determined, corrosion-mitigation coatings are applied to the groundline zone to prevent corrosive activity. Structural ratings are reviewed by our in-house engineering team and recommendations are made for restorations if significant issues are found.

During a predictive assessment, environmental corrosion indicators are collected. Based on those measurements, a forecast is made to diagnose the corrosion behavior on the structure. Predictive assessments provide an economical and effective approach to target the most detrimental conditions on a structure.

Environmental Corrosion Indicators

Corrosion Potential Assessment

During the corrosion potential assessment, each structure is evaluated and given a rating based on the likelihood of future corrosion. This comprehensive rating is determined by the corrosivity of the structure’s environment.

Data-Driven Steel & Concrete Assessment

All relevant data, both structural and environmental, collected during the assessment process is recorded and delivered to the utility.  Customers receive raw data and project summary reports, which summarize findings and provide recommendations for logical and cost-effective mitigation plans.

Accurate, comprehensive data removes any guesswork, allowing customers to address priority concerns immediately and design a condition-based assessment and mitigation program for the second cycle.  Most customers find that lifecycle costs diminish substantially in the next assessment cycle, while service life and reliability are enhanced.

Non-Destructive Evaluation (NDE) Options

When non-destructive evaluation of an asset is necessary, Osmose technicians utilize electromagnetic acoustic transducer (EMAT) technologies such as Intelli-Pole and Anchor-Inspector to identify below-grade structural defects.  These proprietary technologies are specialized NDE methods designed to estimate the extent of the defects.  EMAT technologies are particularly useful for inspecting structures that cannot be excavated, or for structures that have been classified as having severe corrosion potential and require further evaluation without the risk of excavation.  Data compiled from the NDE field inspections is validated by means of separate engineering analysis and delivered via a written report to the customer as their final deliverable.
