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.

Part of the Sustainable Structures Webinar Series: This presentation will give a brief basic overview of insulating concrete forms (ICFs) and precast concrete.  The presenters will answer the following questions:  What are ICFs and what is precast concrete? What are the benefits of each system?  How is each installed/erected?  What types of buildings are constructed from precast concrete and ICFs?

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!!!

A lot is known about Type I Construction (non-combustible) because it has been used for decades for multi-story construction.  Although Type IV Construction (heavy timber) is not new, it is just now beginning to be used with greater frequency in multi-story construction. This presentation will provide an overview of the building code as it relates to Type I and Type IV Construction. Case studies will be used to demonstrate relevant code sections that apply to Type I and Type IV buildings using the current Minnesota Building Code including:

    Chapter 5 – Area and Height limitations of Type I and Type IV
    Chapter 6 – Fire Rating requirements for Type I and Type IV
    Chapter 7 – Fire and Smoke requirements, shafts, sound assemblies  
    Chapter 9 – Fire and Life Safety requirements of Type I and Type IV
    Chapter 23 – Wood and heavy timber construction.  

In addition, materials and special inspections will be discussed for each type of building.

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.

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.

Learning Objectives:
1.    Understand the different types of cracking in concrete.
2.    Understand what causes concrete to crack.
3.    Understand how to evaluate the difference between structural cracks and cosmetic cracks
4.    At the conclusion of the presentation, participants will know how to minimize concrete cracks.

Green building is the concept of constructing buildings we need today without depleting resources for future generations. In the new world of sustainable building, information about the strength, durability, and indestructible nature of concrete as a resourceful building material is emerging. Amid the teardown-and-replace mentality still pervasive in the world today, concrete stands out defiantly. Try to replace concrete with an alternative building material, and you'll be hard pressed to find a substitute possessing the same thermal qualities, design flexibility, and permanence. This presentation will discuss where we are at as a green industry and the various ‘green” efforts that have been used in concrete production, such as substituting relatively high percentage of cement by fly ash (up to 100%), the use of other natural pozzolans, and development of concrete with recycled or waste materials. The presenter will also discuss where the industry might be headed in the future. Finally, problems in the realization of and potential barriers to green concrete construction are also discussed.

There is a lot more to cold-weather concrete than just preventing freezing. This webinar will discuss the reasons to protect concrete in cold weather, the ACI definition of cold weather, methods to protect concrete from freezing, and other topics beneficial to contractors, designers, owners, and suppliers who design and build projects in cold weather.

The performance life of asphalt surfaced parking lots can be extended by placing a bonded concrete layer on top of the existing asphalt. This technique has been used for many years for highway, street, and parking lot pavements but still engineers and owners are unfamiliar with the process. This session will cover the publication entitled the Guide to Concrete Overlays of Asphalt Parking Lots and demonstrate the steps necessary to properly design and construct a concrete overlay.
