Assessing Corrosion Severity on a Pier with Concrete-encased Steel Elements | Florida, USA
Services Applied by VCS Engineering
Project Description
VCS Engineering carried out a feasibility assessment on an inverted pyramid structure at a Pier in Florida. The study included on-site investigation of the concrete-encased steel elements to evaluate durability and explore strategies for extending the structure’s long-term service life.
Project Issue
The inverted pyramid, built in the 1970's, is supported by a concrete-encased steel frame with deep foundation elements. VCS Engineering was engaged to evaluate the current condition of the structure and to determine whether rehabilitation strategies could extend its long-term service life.
Project Solution
The feasibility assessment focused on durability and long-term serviceability of the concrete-encased steel structure. Inspection methods included visual survey, select concrete openings, and material sampling to evaluate concrete cover, resistivity, and corrosion risk near steel elements.
Corrosion potential measurements were also made in various zones to identify areas with elevated risk. Based on the assessment, VCS collaborated with project engineers to recommend mitigation strategies for different structural components, aimed at prolonging usable service life.
