The structural evaluation process of existing concrete structures involves the understanding of existing capacity, safety, and future expected life. Evaluation and repair or strengthening of deteriorated concrete structures requires specific tasks and responsibilities of owners, licensed design professionals (LDPs), and contractors. One session discusses these tasks and responsibilities for each entity. And more specifically identifies and explains evaluation testing methods both non-destructive and destructive (cores) that are responsibilities of the LDP. The other session discusses evaluation and repairs of two interesting 1970’s parking structure renovation projects—an unbonded post-tensioned slab deck repair project and a precast prestressed double tee with concrete topping deck and beam repair project.

The contents of this course include two recorded presentations from the ACI 2016 Fall Convention:
1. Concrete Repairs: Tasks and Responsibilities by Benjamin Lavon, GEI Consultants, Inc.; and Pericles C. Stivaros, GEI Consultants, Inc.
2. Evaluation and Repair of Two RC Parking Structures by James Labelle, Computerized Structural Design; and Mahmoud Maamouri, Computerized Structural Design SC

1. Explain the tasks and responsibilities of owner groups, licensed design professionals, and contractors on concrete evaluation, repair and renovation of deteriorated or damaged concrete structures.
2. Identify potential evaluation methods and strategies for rehabilitation of concrete structures.
3. Describe techniques to renovate and repair damaged or corroded parking deck slabs with unbonded post-tensioned tendons.
4. Recognize the engineering challenges of evaluation and repair of existing structures. Describe successful techniques to repair and renovate deterioration in prestressed precast concrete parking structure, including punching shear overstress in slabs, and spalling at deck expansion joints.
