This thesis is an investigation into four current concrete repair contracts at harbours in the Western Cape. The works are critiqued in terms of repair philosophy and methodology, and recommendations are made for improving practice. A literature review is presented, outlining the relevant background to the chlorideinduced corrosion of reinforcing steel, specifically in the marine environment.

The contract documentation for the four contracts is reviewed, and it is highlighted that while the bulk of the project specification is identical, the major differences in the documentation from the four contracts are in the quality and level of detail of the construction drawings. The individual repair methods chosen for various concrete elements are described in detail and commented on in terms of concrete durability. Forensic testing results in the forms of chloride profiling and corrosion inhibitor testing at two locations are presented.","abstract_html":"Damage to reinforced concrete infrastructure due to chloride-induced corrosion is widespread throughout the marine environment in South Africa.
