Abstract : Structural damage resulting from corrosion of steel-clad structures can be of concern, especially when the steel is part of electromagnetic shielding of an underground structure. The US Army Corps of Engineers was called to lend assistance by having its corrosion experts and research laboratories investigate the condition and extent of corrosion at such a structure (Site 81) in Israel. This report documents the investigation, conclusions, and recommendations. In summary, from investigation and analyses of core samples, no significant corrosion was discovered and the estimated minimum service life of the existing structure is 199 years.
