10/21/20 | Construction Special Inspections | Rob Flickinger and Derek Van Heuveln (American Engineering Testing) | 1 Hour |
Anyone who has watched a building under construction can appreciate its … Anyone who has watched a building under construction can appreciate its complexity and sophistication. 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. |

The Portland Cement Association’s newly released Roadmap to Carbon Neutrality lays out the cement and concrete industry’s commitment to a lower carbon future. With its proven performance, portland-limestone cement, or PLC, is ready to play a key role, yet many designers and specifiers don’t know about it.

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. |

5/25/22 | Ultra High Performance Concrete (UHPC) – Design and Application | Travis Konda (Senior Technical Advisor, HNTB) and Mario Ratnaraj (Bridge Engineer, HNTB) | 1 Hour |
Ultra High Performance Concrete (UPHC) describes a class of concrete mat… Ultra High Performance Concrete (UPHC) describes a class of concrete material with a unique set of properties including: Strengths of 21,000 ksi plus, high ductility, low permeability and rapid strength gain. With these unique material properties, UHPC facilitates short development lengths, thin overlays and the potential for further development in optimized prestress girders for longer spans with less material. UHPC continues to play an important role in Accelerated Bridge Construction serving as the connecting material between precast elements allowing for small joints with short lap lengths while obtaining full connectivity between the elements. This presentation will introduce the audience to UHPC, the basic material properties, applications and lessons learned. |

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. |

6/8/21 | The Top 10 Ways to Reduce Concrete’s Carbon Footprint | Donn C. Thompson AIA, LEED AP BD+C (National Ready Mixed Concrete Association) | 1 Hour |
Concrete is unique among building materials. Its formulation is highly i… Concrete is unique among building materials. Its formulation is highly influenced by its application. 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. |

As physical sites grow and expand, means and methods for property develo… As physical sites grow and expand, means and methods for property development become much more complex. With abbreviated construction schedules and significant liquidated damages, the ability to gain some control of the uncontrollable becomes essential. The earlier this process is recognized and integrated into the project, the better the chance for success. This presentation will address several ways to work with challenging construction sites using cement and concrete; delivering large projects to the owner on time, economically and sustainably. |

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. |
