Assessment and Rehabilitation of Wharf
Structures in the Houston Ship Channel

Abstract
Managing aging civil infrastructure is a complex and capital-intensive task; repair and rehabilitation of such infrastructure therefore is crucial and offers several cost benefits. This presentation focuses on assessment and rehabilitation of port facilities, providing a case studies specific to corrosion of reinforced concrete wharves at the Houston Ship Channel. The presentation includes various investigation and analysis techniques, including document review, visual and nondestructive testing, material sampling, and underwater inspection. Laboratory testing; load rating, and service life analysis are also discussed. Based on the assessment results, options for repair or strengthening can be determined and, ultimately, construction documents for rehabilitation can be developed. Different options for repair are provided, including a comparison of the benefits of each. This presentation illustrates how this approach has been implemented for marine and civil infrastructure in the Houston Ship Channel.
Since joining WJE in 2010, Stephen Foster has been involved in the evaluation, design, and rehabilitation of numerous engineering projects, including concrete, steel, wood, and masonry structures. He has performed assessments related to corrosion distress, design and construction deficiencies, foundation-related movement, and leakage distress.
Mr. Foster is experienced with preparing construction documents and has performed construction administration work on several repair projects, including experience with numerous field testing and ASTM procedures. He also has experience and specialized NACE training for assessment, specification, and quality assurance inspection of concrete and steel coating systems.
Prior to joining WJE, Mr. Foster worked as a graduate research assistant investigating the optimization of bridge deck reinforcement for a research project sponsored by the Texas Department of Transportation. While at the University of Texas, he worked as a field engineer with a general contractor and as a structural designer with an architectural engineering firm.
