| 1/13/21 | Better Design Through Embodied Carbon - Part One of the Sustainable Structures Webinar Series | Emily Lorenz, PE | 1 Hour |
Part of the Sustainable Structures Webinar Series… Part of the Sustainable Structures Webinar Series: Now that architects have a good understanding of environmental impacts related to energy use, the next design frontier in tackling climate change is reducing the embodied carbon in buildings. This live webinar will focus on best practices for determining the embodied carbon in a building, including credible sources for embodied carbon data. It will introduce common practices and misconceptions about comparisons of embodied carbon. A case study will be presented that highlights how design decisions may be influenced when comparing among up-front carbon, use-phase carbon, or whole-life carbon. The presentation will highlight existing tools related to quantifying embodied carbon. |

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. |

| 2/3/21 | Building More than Just the Pedestal: An Owner/Developer’s Perspective on Building All Concrete Multifamily Mid-Rise | Ryan Bedford (Bedford Development) | 1 Hour |
Part of the Sustainable Structures Webinar Ser… Part of the Sustainable Structures Webinar Series: Look around and you’ll see many five to seven story projects being built today with a one- or two-story concrete pedestal, supporting up to five floors of steel or wood frame. These “pedestal” projects are assumed to be the cheapest way to build while longer term ownership implications of these designs are not well understood. This one-hour presentation dispels the myths that are driving the popularity of pedestal construction and demonstrates the value concrete provides. The developer/owner’s perspective on building multi-family housing projects with Insulating Concrete Forms (ICFs) will be presented, and will include design, construction, and energy-efficiency implications, as well as tenant satisfaction. The presenter will overview his use of ICF’s and concrete for the exterior wall system at Kendal Lofts, a 42-unit project in Waukesha, Wisconsin. In addition, the presenter will also discuss his latest all-concrete residential projects in Wisconsin and Florida. |

| 2/10/21 | Precast Concrete Storm Shelters | Paul Todd (Todd Architecture) | 1 Hour |
Part of the Sustainable Structures Webinar Ser… Part of the Sustainable Structures Webinar Series: This one-hour program is intended for professional designers and engineers. The attributes of precast concrete will be presented, demonstrating how these qualities may be applied to the design and construction of safe and efficient storm shelter facilities. The versatility and resiliency of precast concrete will be further highlighted by a video demonstration, and a series of case studies. |

| 2/9/21 | Performance Based Specifications Support Sustainability | Colin Lobo, Ph.D., P.E. (NRMCA) | 1 Hour |
With the increased focus on sustainability initi… With the increased focus on sustainability initiatives in construction, prescriptive requirements in specifications often restrict the concrete producer’s ability to optimize concrete for sustainability without compromising functional performance for project needs. The presentation will discuss these impacts and outline the development of a guide performance specification by ACI Committee 329. |

| 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. |

| 11/8/23 | Evaluation of Concrete Core Test Results According to ACI 318-19 | Luke Snell, P.E. | 1 Hour |
This presentation by Luke Snell, P.E. and an H… This presentation by Luke Snell, P.E. and an Honorary Member of ACI will take us step by step through the process of how to make a decision with core test results. Remember everyone is on edge when cores are needed – the concrete may be below strength and correction measures even removed may be needed!!! |

| 8/10/23 | Communicating Sustainability: How to share your message about sustainable initiatives. | Kimberly Kayler, CPSM, President, AOE | 1 Hour |
The concrete industry has a goal of carbon neu… The concrete industry has a goal of carbon neutrality by 2050. In response to this goal, many industry organizations are tasked with getting their message related to decarbonization and sustainability to their customers, specifiers, and employees. Transparency and recognition of goals and achievements are vital. Kimberly will discuss a variety of methods and materials that should be used to effectively communicate progress. Kimberly will help you identify key ways to communicate the steps your organization is taking, whether that be in the form of a new product or innovative process, that will help your organization reach your sustainability goals. |

| 1/10/24 | Concrete Basics for Young Professionals | Tyler Ley, PhD, PE, FACI, FAcerS | 1 Hour |
Many issues related to construction can be all… Many issues related to construction can be alleviated by a fundamental understanding of the basics of concrete. This starts with knowledge of the standard components of a concrete mixture including cementitious materials, aggregates, water, and admixtures and their importance on the properties of fresh and hardened concrete. The combination of these materials in various proportions can produce mixtures suitable for a wide range of applications and placement methods. Once placed, the concrete must be properly cured to develop its intended properties. This presentation introduces the basics of concrete and describes its importance and application as a construction material. |

| 9/13/23 | Shoring and Reshoring Loads, Safety, Cost, Schedule, Concrete and Responsibility | Professor Ken Hover, Cornell University | 1 Hour |
Forms, shores, and re-shores are a temporary s… Forms, shores, and re-shores are a temporary structure that carries the weight and construction load of the permanent structure until it is strong enough to stand up for itself. While serving this temporary duty, forms, shores, and re-shores impact construction safety, cost, productivity, and schedule, and influence appearance, deformations, tolerances, and cracking of the hardened reinforced or prestressed concrete.
This presentation introduces Codes, standard specifications, OSHA, and ANSI documents that address responsibilities for forms and shores. By an example of a multi-story building, we look at how shore and re-shore systems work, including how shoring & re-shoring plans must be synchronized with rate-of-strength-gain of the concrete, as influenced by mix-design and ambient temperature. This complex topic demonstrates how schedule, concrete mix, weather, construction technology, lab and in-place testing all come together. |
