Detailed Webinar Instructions
The repair of concrete structures presents unique construction challenges compared to new construction. These often include variations in the as-constructed details compared to those shown in design and construction drawings. Moreover, for buildings that have been in service for some time, the aging and deterioration of components can make construction more difficult, especially if the building must remain in service during repairs.
To describe some of these challenges, this presentation will focus on the evaluation and repair of two high-profile concrete buildings using ACI 562 – the Courthouse Square mid-rise building complex in Salem, Oregon, and the Austonian high-rise residential tower in Austin, Texas. The presentation will discuss the nature of design and construction defects that were uncovered during investigation, the types of concrete deterioration that had been experienced during service, and the types of repair and strengthening schemes that were utilized to bring the buildings into compliance with building codes.
Table of Contents
1. Describe the nature of the design and deterioration issues as well as construction defects that led to the need for evaluation and repair of both buildings.
2. Explain the evaluation and non-destructive testing methods that were utilized to assess the condition of the buildings and to determine the causes of the various mechanisms that led to distress.
3. Review how ACI Committee 562 Assessment, Repair, and Rehabilitation of Existing Concrete Structures -- Code and Commentary was utilized on both buildings to provide a framework for repair and strengthening.
4. Identify some of the unique types of repairs that were utilized to successfully bring the buildings into compliance with building codes.
