H-3 North Halawa Valley Viaducts: Five-Year Monitoring Program

Instrumentation and monitoring of the North Halawa Valley Viaduct performance was initiated in 1994. Installation of the monitoring instrumentation was completed in 1994. Monitoring after installation of the instrumentation ended on December 31, 1999. The most valuable outcome of this first monitoring project has been the development of more reliable procedures for long-term prediction of structural performance, particularly for concrete structures affected by creep and shrinkage. This new project will continue the monitoring and reporting of results for an additional five-year period for the following reasons: (1) the instrumentation is still in excellent condition; (2) continue monitoring would greatly enhance the standard bridge inspections performed by the State and would improve assessment of the bridge performance; and (3) continued monitoring would extend the long-term data collection and greatly improve the evaluation of long-term analytical prediction models for use in future bridge design. This project will include monitoring the condition and performance of the viaduct, including prestress losses, deflections and concrete strains; and evaluating the collected data to derive information that will assist in the maintenance of the structure and the design of future segmental concrete bridges.
