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… View Description ---Close--- 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.

12/8/21	Workability and the Impact of Workability Retention	Joseph Daczko (Master Builders Solutions)	1 Hour	Contractors want concrete to be as workable as possible to facilitate pl… View Description ---Close--- Contractors want concrete to be as workable as possible to facilitate placement and consolidation without compromising performance in the hardened state. Concrete producers strive to consistently deliver expected performance attributes. Yet, hydration of Portland cement leads to a change in fresh concrete properties immediately after batching, most notably with respect to mix slump or workability. In air-entrained concrete mixtures, furthermore, modified slump can lead to changes in air content, typically a reduction, and potential rejection of the load. Invariably, rejected loads result in loss of revenue and reduced profits for concrete producers. This presentation will discuss workability retention and the various methods traditionally used to manage it. Additionally, an innovative, new admixture is introduced that provides workability retention without the adverse effects of current practices.	View Video	View Handout
2/23/22	How Do I Write a Sustainable Concrete Specification?	Donn Thompson AIA, LEED AP BD+C (National Ready Mixed Concrete Association)	1 Hour	Concrete is used in nearly every structure we build today, including bui… View Description ---Close--- Concrete is used in nearly every structure we build today, including buildings, bridges, homes and infrastructure. 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. Performance-based specifications for concrete represent an important synergy with sustainability initiatives because they provide the opportunity to optimize mixtures for performance that can also reduce environmental impacts. Prescriptive specifications often adversely impact the environmental footprint of concrete structures. This presentation outlines how concrete performance can be improved while lowering environmental footprint by implementing performance-based specifications.	View Video	View PDF
3/8/22	Implementation of the Strut-and-Tie Method	Gary Klein, P.E., S.E. and Jeremiah Fasl, PhD, P.E. (Wiss, Janney, Elstner Associates, Inc.)	1 Hour	Gary Klein addresses how the strut-and-tie method is implemented for var… View Description ---Close--- Gary Klein addresses how the strut-and-tie method is implemented for various types of discontinuity regions such as deep beams, corbels, and post-tensioning anchorage zones. Jeremiah Fasl shares an example of how the method was used for design of the crane support beam at Barbours Cut Terminal at the Port of Houston.	View Recording	View PDF
4/6/22	Building Ethical Cultures	Nicole Zwieg Daly, J.D., Ed.D. (University of St. Thomas)	1 Hour	Ethical business cultures continue to prove to be more productive, more … View Description ---Close--- Ethical business cultures continue to prove to be more productive, more innovative, and more meaningful places to work. Let's discuss how to build - and more importantly maintain - an ethical business culture. During this session, learn a little theory and a lot of practical knowledge to maintain your ethical business culture.	View Recording	View PDF

Although Type IV Construction (heavy timber) is not new, it is just now beginning to be used with greater frequency in multi-story construction. This presentation will provide an overview of the building code as it relates to Type I and Type IV Construction. Case studies will be used to demonstrate relevant code sections that apply to Type I and Type IV buildings using the current Minnesota Building Code including: Chapter 5 – Area and Height limitations of Type I and Type IV Chapter 6 – Fire Rating requirements for Type I and Type IV Chapter 7 – Fire and Smoke requirements, shafts, sound assemblies Chapter 9 – Fire and Life Safety requirements of Type I and Type IV Chapter 23 – Wood and heavy timber construction. In addition, materials and special inspections will be discussed for each type of building.	Recording Not Available	View Handout

Second is what happens when a fire does occur, how does it affect the concrete, and what assessments and testing can be completed onsite to determine repair or replacement options.
