Rehabilitating and Rebuilding Infrastructure: Precast Concrete’s Key Role
Wednesday, November 11
Noon – 1:30 p.m. Eastern (1.5 PDH)
Speaker: Kevin MacDonald, P.E., President & Principal Engineer of Beton Consulting Engineers LLC
The need for resilient, long-lasting, durable infrastructure is more apparent now than ever before. The American Society of Civil Engineers’ Infrastructure Report Card recently rated America’s infrastructure a D+. This means the framework upon which society functions, including our roads, bridges, dams, drinking water treatment and conveyance structures, waste management facilities, schools, and airports just to name a few, are in a state of disrepair, are operating over capacity, and are remaining in service longer than they were ever designed to last. As a result, our infrastructure is disrupting society’s daily functions and costing local governments more to maintain, and citizens are left to bear the consequences.
As we look to rehabilitate existing structures when possible and rebuild when needed, resilient construction must be top of mind. Additionally with more aggressive and increasingly frequent climatological events occurring across the world, the ability of our essential infrastructure to endure these catastrophic events and remain functional afterward is crucial.
During this webinar, we will look at what resilient infrastructure is and how it relates to service life, capacity, durability, and sustainability. We will discuss fundamental characteristics of resilient infrastructure and learn how precast concrete will play a key role in both rehabilitation work and new construction in the coming years. We will also review case studies covering a variety of structures in different geographical regions.
Addressing Microbial Induced Corrosion in Precast Concrete Structures
Thursday, December 10
Noon – 2:00 p.m. Eastern (2 PDHs)
Speaker: Claude Goguen, P.E., LEED AP, Director of Outreach & Technical Education, NPCA
Precast concrete structures are known for their durability. Manufacturers of quality precast products assess threats on durability based on product use and environmental conditions and designs are updated accordingly. A potential issue unique to water treatment and conveyance structures is Microbial Induced Corrosion (MIC). Although only seen in a very small number of installations, NPCA has been heavily engaged in studying the phenomenon of MIC in order to address durability concerns. Over the last 10 years, NPCA has commissioned two major studies on MIC and has been a partner in a third project with ASTM.
During this webinar, we will share what we’ve learned about the process of MIC. We will explain the unique conditions necessary for MIC to occur and how it progresses. We will discuss different ways to avoid or disrupt the process of MIC and examine proactive system design considerations to not only prevent MIC, but also make the system safer for ongoing maintenance. We will also discuss what precast manufacturers are doing to ensure the durability of precast when exposed to MIC conditions and what newer technologies are available to protect structures and ensure proper long-term performance.
At the conclusion of this webinar, you will be able to:
- Describe the three phases of MIC development
- Explain changes in system design that can alter environmental conditions to prevent MIC
- Summarize what precast manufacturers are doing to protect their products from the effects of MIC
