|1/6/21||The Use of Insulating Concrete Forms for Commercial Construction - Contractor's Perspective||Justice Olson (Nudura) and DC Mangimelli (Fox Blocks)||1 Hour||

Lighter, faster and more cost effective than other forms of construction, Insulating Concrete Forms (ICFs) are quickly becoming the construction method of choice for all forms of construction including single and multi-family, hotels, schools, offices. Concrete contractors, masons and framers have an opportunity to learn how their trade can work with ICFs to enhance their competitiveness in today’s construction environment. The presentation will focus on how to communicate basic ICF detailing, design efficiencies, and other necessary information to designers who may not be familiar with ICF construction. Also included in the presentation will be information on how ICF’s can affect other sections of the specification, best construction practices, and tips on how to determine labor costs for an ICF project.

The use of Fiber Reinforced Concrete continues to evolve and become more common place in everyday concrete construction. Learn how the new ACI 544.4R document can help ready- mix producers, engineers and contractors by providing a roadmap to designing FRC for many applications including floors, precast, shotcrete and paving applications. An update will also be provided on other CODE approvals such as UL fire classification for composite deck designs, various DOT initiatives for paving with FRC and the improvements in ASTM and other test methods to verify correct fiber selection and quantities in concrete.
|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 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.
|11/4/20||Economic, Construction & Cement Outlook: Cyclical & Structural Changes Resulting from Covid||Dave Zwicke (Portland Cement Association)||1 Hour||

The webinar covers Minnesota's cement/concrete trends and where the market is headed in the next few years. We will examine economic growth scenarios that may unfold under differing assumptions regarding COVID-19. Where are the growth opportunities? Will there be structural changes to the construction market following the recession? The presenter is Dave Zwicke who is Sr. Director of Economic Analysis at the Portland Cement Association.

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.

There are five commonly used procedures for designing industrial floor slabs. All of them are effective when their recommendations and details are followed. So, how does a designer choose the best method for a particular floor? The most common approach is to determine the type of floor construction needed for expected loading conditions. Then, from the design procedures, select the most appropriate method for determining floor thickness, reinforcement, joint spacing, and other details. This presentation will discuss the ACI 360 “Guide to Design of Slabs on Ground”. It will briefly address the planning, design, and detailing of slabs. Background information on design theories is followed by discussion of the types of slabs, soil-support systems, loadings, and jointing. Some worked design examples for various types of concrete slabs-on-ground will also be covered.

Concrete provides structures with strength, rigidity, and resilience from deformation. These characteristics, however, result in concrete structures lacking the flexibility to move in response to environmental or volume changes. Cracking is usually the first sign of distress in concrete. Cracking of concrete flatwork is natural, expected, and accepted. However, cracks may affect appearance, performance, and maintenance costs. This presentation will discuss the various types of concrete cracks and how to best minimize their occurrence.

This webinar will outline the benefits of using Insulated Concrete Forms (ICFs) in construction, especially in regard to Rural and Tribal projects. ICFs are a key component in DSGW’s strategy to design Net Zero projects. This presentation will show examples of ICF and Net Zero design, in particular the Fort Totten Alternative CTE School, the country’s first Net Zero school on Tribal lands in North America.
The 12,500 square foot, $3.8 million net zero Fort Totten Alternative CTE School was designed to produce more energy than it consumes while ensuring to meet other standards common when designing a net zero facility. There are other net zero schools in the United States, but this new school is the first to be built on tribal land and the first in North Dakota.

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.
