WSP Concrete Forensic and Materials Investigation SOQ

FirmQualifications | SOQ

WSP uses state of the art methods and equipment to evaluate the cause and extent of concrete distress. Our results are used by structural engineers to aid in their design of repairs and retrofits.

Approach During a typical materials investigation, WSP makes visual observations of the existing condi tions. This may include photographic documen tation, personnel interviews, and review of plans, specifications, and existing documents/records. Locations for in-place testing are selected and ap propriate samples are taken for laboratory testing and analysis. Based on the results of such tests and observations, WSP’s engineers perform detailed evaluations and provide reports with the necessary conclusions and appropriate recommendations for materials related issues. Some concrete distress is readily visible, often the original cause of the distress is not so readily ap parent. WSP uses state of the art non-destructive testing equipment and techniques to evaluate con crete structures. Concrete distress can be initiated by many distress mechanisms. Often the corrosion of the reinforcing steel and visible spalling of the concrete is a secondary condition and not the orig inal cause of the distress. To develop a cost-effective rehabilitation program that meets your clients’ needs, budget, and ex pected design life, the initial cause of the observed distress needs to be determined as well as the current physical and chemical composition of the concrete. WSP uses this information to develop plans and specifications for the rehabilitation of the deteriorated cracked concrete.

For San Francisco’s Dumbarton Bridge, WSP used Ground Penetrating Radar (GPR) to locate couplers and evaluate the layout of reinforcing steel.
