| 7/23/20 | FIU Pedestrian Bridge Collapse: Testing of Full-Size Replicas of Failed Connection | Gary J. Klein, PE, SE | 1 Hour |
WJE carried out independent studies related to the 201… WJE carried out independent studies related to the 2018 collapse of the FIU Pedestrian Bridge in Miami. Most significantly, WJE developed and tested full-sized specimens to evaluate the significance of the National Transportation Safety Board’s (NTSB’s) finding that the construction joint between the northernmost diagonal and deck was left in an as-placed condition, rather than intentionally roughened as required by the project specifications. The webinar also describes WJE’s independent review of shear friction strength in accordance with the AASHTO Code.
The presentation describes the details of the experimental program that demonstrated that, had the construction joint been roughened as required by the project specifications, the collapse would not have occurred. Contrary to NTSB’s findings, the contractor’s failure to roughen the surface was the primary cause of the collapse. |

| 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. |

| 11/12/20 | Ethics - Not Black and White but Shades of Gray | William Rushing, P.E., F.ACI (Vice President, Waldemar S. Nelson & Co., New Orleans, LA) | 1 Hour |
Making a decision that requires ethical consideration is usually not eas… Making a decision that requires ethical consideration is usually not easy. Rarely are we faced with an ethical question that has a corresponding answer that is clearly black and white. Doing the ethical thing can require effort and determining the correct path may include many variables that cause us to pause and consider what the right decision is. In this presentation, the speaker will discuss some scenarios that illustrate the grey area that can be "ethics." The presenter will work through the scenarios an offer insight on determining the correct and ethical way to proceed through a decision-making process. |

Occasionally, inspection and testing requirements occur that the local code official may not be qualified or experienced to address, so third-party assistance is needed. The building codes address this need through a specific requirement for structural tests and “special” inspections. A special inspection can be required for materials, installation, fabrication, erection or placement of components and connections where special expertise is needed. This presentation will cover the requirement of special inspections as well as some examples of when construction testing and inspections did not go as planned. |

So why can’t I find one that can move this perfect mix I just created? The factors that can affect concrete pumping are numerous, inter-related, and sometimes hidden, making the predicting of pumpability seem elusive. So how is the construction industry, which is becoming ever more cost conscious and filled with complicated and demanding concrete requirements, to deal with it on a more simplified level? This presentation will discuss some of the over 50 factors that affect concrete pumping, the basics of how concrete pumping works, how mix designs can be adjusted to accommodate the application’s multiple requirements, and what can be done to help eliminate the jobsite problems that result in a finger pointing exercise and costly downtime. |
