Post-Tensioning Repair Team Leader Scott Greenhaus Design-Assist & Engineered Product Support • Investigation Support • Solution Development • Budget Development • Specification Assistance • Constructability Consulting • Application Engineering • Quality Control Programs • Project-Specific Design-Assist Investigation & Assessment Support STRUCTURAL TECHNOLOGIES offers a range of specialized investigation services to assist engineers with the assessment of post-tensioned concrete structures. Our assessment services and phased approach are designed to identify the root cause of concrete and post-tensioning system deterioration. A more thorough evaluation of a post-tensioned structure involves a variety of non-destructive and exploratory testing to determine the condition of the post-tensioning system and the surrounding concrete. STRUCTURAL TECHNOLOGIES also offers a series of advanced testing methods to gain detailed information on the condition of the structure – or to provide estimated remaining service life based on deterioration levels and exposure conditions. Our assessment toolbox includes a variety of proven and advanced technologies, including: Magnetic methods Mechanical impact / wave propagation methods Ground Penetrating Radar (GPR) X-ray Strand tension testing (monostrand, multistrand & stay cable systems) Anchorage inspections Borescope inspections for grouted tendons High/low point inspections Electrochemical testing & analysis Engineering & Design Support Services Whether repairing the post-tensioning system, or adding supplemental structural support, STRUCTURAL TECHNOLOGIES’ in-house team of engineers provides application design support to provide value-added solutions to engineers and owners of concrete infrastructure. Our design specialists have extensive experience, and are active members of technical organizations and committees including the American Concrete Institute (ACI) and the Post-Tensioning Institute (PTI). During the design phase, we can also assist engineers by developing Finite Element Analysis (FEA) models to evaluate various repair solutions to predict future performance of the structure – to help select the best repair solution.
