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.

Hot weather conditions are not solely related to the air temperature when placing concrete.  Those conditions are defined in ACI and ASTM documents.  This presentation will focus on being able to define hot weather conditions and its effects on concrete in the plastic and hardened state.  This presentation will also provide details on how to overcome the conditions of hot weather when placing concrete.

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.

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.

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.
