SKA performed an engineering assessment to determine the root cause(s) of cracking of the hardened concrete and to provide an opinion on the general condition and future anticipated service life of the dam. Our assessment found that the strength and integrity of the concrete buttresses, spillways, and wing walls of this dam were compromised by cracking distress of the concrete caused by the deleterious and destructive mechanisms of alkali-silica reaction (ASR) and secondary ettringite formation (SEF) within the hardened paste and aggregates of the hardened concrete. SKA was subsequently contracted for the remediation repair.
