| 1/27/21 | Resiliency – Consideration Beyond Code Requirements | Shamim Rashid-Sumar, PE, FSFPE (National Ready Mixed Concrete Association) | 1 Hour |
Part of the Sustainable Structures Webinar Series… Part of the Sustainable Structures Webinar Series: Prescriptive building code requirements represent provisions for the least safe structure that may legally be built in a jurisdiction. Over the past 20 years, the building design and construction industry have witnessed an increase in the number of trade-offs of passive fire safety features for active systems. As natural disasters attributed to climate change continue to escalate, the population of neighborhoods located along with the wildland-urban interface increases, and fire and emergency access to buildings in densely populated areas is obstructed, multiple drivers arise to consider more robust construction for our built environment. The presentation will provide an overview of increased risks from natural and human hazards, identify approaches to mitigate their effects through voluntary and mandatory strategies and demonstrate the importance of incorporating standards for resiliency beyond minimum code requirements. |

With greater emphasis placed on sustainability, design professionals are faced with the challenge of meeting traditional design criteria with evolving criteria that support green building and efforts to reduce impact on climate change. When looking at the environmental impact of a building, it is important to assess every stage of the environmental life cycle, from material extraction and product manufacturing to building operations and maintenance through to end-of-life. Concrete offers many environmental attributes that help reduce the overall environmental life cycle impacts of a building. This learning session explores how life cycle assessment can be used to measure and lower the environmental impacts of concrete buildings. |

| 11/18/21 | Ethics - Why Do Good People Do Bad Things? | David Schultz (Hamline University) | 2 Hours |
Why do good people and organizations act unethically? Architects and eng… Why do good people and organizations act unethically? Architects and engineers may confront ethical dilemmas in many forms during their professional practice, especially in the public arena. Many think that only unethical people do bad things, and that ethical people generally do not do bad things. However, the reality is that is often not the case, and this presentation will discuss why good or ethical people often act unethically. In this program, attendees will examine the Minnesota Rules of Professionalism and Ethics and examine examples of ethical dilemmas in professional practice. Specific case studies will be used to provide a foundation for an analysis regarding how the fostering of ethical diversity and thinking about one's personal ethics within organizations can prevent the slippery slopes that lead to administrative evil or unethical behavior. |

Green building is the concept of constructing buildings we need today wi… Green building is the concept of constructing buildings we need today without depleting resources for future generations. In the new world of sustainable building, information about the strength, durability, and indestructible nature of concrete as a resourceful building material is emerging. Amid the teardown-and-replace mentality still pervasive in the world today, concrete stands out defiantly. Try to replace concrete with an alternative building material, and you'll be hard pressed to find a substitute possessing the same thermal qualities, design flexibility, and permanence. This presentation will discuss where we are at as a green industry and the various ‘green” efforts that have been used in concrete production, such as substituting relatively high percentage of cement by fly ash (up to 100%), the use of other natural pozzolans, and development of concrete with recycled or waste materials. The presenter will also discuss where the industry might be headed in the future. Finally, problems in the realization of and potential barriers to green concrete construction are also discussed. |

There are five commonly used procedures for designing industrial floor s… There are five commonly used procedures for designing industrial floor slabs. All of them are effective when their recommendations and details are followed. So, how does a designer choose the best method for a particular floor? The most common approach is to determine the type of floor construction needed for expected loading conditions. Then, from the design procedures, select the most appropriate method for determining floor thickness, reinforcement, joint spacing, and other details. This presentation will discuss the ACI 360 “Guide to Design of Slabs on Ground”. It will briefly address the planning, design, and detailing of slabs. Background information on design theories is followed by discussion of the types of slabs, soil-support systems, loadings, and jointing. Some worked design examples for various types of concrete slabs-on-ground will also be covered. |

| 4/22/21 | Mass Concrete Constructability | Oscar R. Antommattei, MS, PE, FACI (Chief Concrete Engineer & Materials Engineering Manager, Kiewit) | 1 Hour |
Mass concrete (or thermally controlled concrete) typically requires impl… Mass concrete (or thermally controlled concrete) typically requires implementing thermal control measures to reduce maximum temperature and mitigate temperature difference. Specified temperature limits and thermal control requirements can affect mix design proportions, materials selection, reinforcement details, construction operations and compliance to specifications for the work. Many specifications still limit concrete temperatures to overly conservative default values without recognizing concrete properties and performance that allow alternative temperature limits more suitable for the specified work while maintaining quality and improving constructability. This issue frequently results in challenging scenarios that create design difficulties and unnecessary constructability problems for mass concrete. This presentation focuses on the implementation of today’s knowledge of mass concrete and best practices to overcome mass concrete challenges and facilitate solutions in projects. A special emphasis will be given to the technical updates provided for mass concrete requirements and guidance progressing in North America industry standards. |

Design professionals and contractors have a greater influence on concrete formulation than they do with other building products. Concrete can be made stronger, lighter, more flowable, stiffer, less permeable, and even weaker depending on performance needs. No other building material is that versatile. This presentation will discuss how design and construction teams can implement ten simple strategies to reduce concrete’s carbon footprint today. The recommendations are listed broadly in order of priority, but not in order of impact reduction. All are important and should be implemented. In addition, the strategies are meant to achieve a lower carbon footprint without impacting other desired performance capabilities for the concrete. |
