How to deal with concrete defects?
Complimentary webinar for owners, contractors, attorneys, insurers, engineers, architects, and other construction industry professionals.
May 21, 2020 1:00 PM Central Time.
Continuing education credit offered for engineers (1.0 PDH)
Best practices and procedures related to addressing issues with defective in-place concrete will be highlighted using a case study of a recent CTLGroup project. Concerns about possible subsurface defects stalled construction at a large building project in Southeast Asia until an evaluation program and rational acceptance criteria were developed. CTLGroup guided the owner, contractor, and designer through the investigation and repair process. The consulting team developed acceptance standards and conceptual designs that satisfied the owner’s construction schedule requirements and that were acceptable to the designer. Importantly, the program was designed to minimize or avoid unnecessary and costly remediation work.
This webinar will help owners and contractors who will inevitably find themselves facing questions about the quality and consistency of critical defective in-place concrete components.
By attending this webinar, participants will be able to:
- Discuss the significance of representative sampling, and what constitutes a representative sample;
- Describe the mechanics of concrete shear transfer behavior;
- Identify the best practices for core sampling and core evaluation; and
- Understand the engineering approach to the development of practical repair concepts.
Live Q&A will follow the presentation.
