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.

View Description

---Close---

Concrete is used in nearly every structure we build today, including buildings, bridges, homes and infrastructure. 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.

View Description

---Close---

Contractors want concrete to be as workable as possible to facilitate placement and consolidation without compromising performance in the hardened state. Concrete producers strive to consistently deliver expected performance attributes. Yet, hydration of Portland cement leads to a change in fresh concrete properties immediately after batching, most notably with respect to mix slump or workability. In air-entrained concrete mixtures, furthermore, modified slump can lead to changes in air content, typically a reduction, and potential rejection of the load. Invariably, rejected loads result in loss of revenue and reduced profits for concrete producers. This presentation will discuss workability retention and the various methods traditionally used to manage it. Additionally, an innovative, new admixture is introduced that provides workability retention without the adverse effects of current practices.

View Description

---Close---

Why do good people and organizations act unethically? Architects and engineers may confront ethical dilemmas in many forms during their professional practice, especially in the public arena. Many think that only unethical people do bad things, and that ethical people generally do not do bad things. However, the reality is that is often not the case, and this presentation will discuss why good or ethical people often act unethically. In this program, attendees will examine the Minnesota Rules of Professionalism and Ethics and examine examples of ethical dilemmas in professional practice. Specific case studies will be used to provide a foundation for an analysis regarding how the fostering of ethical diversity and thinking about one's personal ethics within organizations can prevent the slippery slopes that lead to administrative evil or unethical behavior.

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.

View Description

---Close---

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.

This presentation will discuss changes in the volume of air entrained concrete in pumped concrete. The work shows that during pumping the air volume will decrease and if measured immediately after pumping will be lower than what is found in the final concrete. These findings are supported by hardened air void analysis, freeze thaw tests, and measurement of the air void volume and spacing over time in the fresh concrete with the Super Air Meter. The presentation makes recommendations for modifications to the current testing specifications based on the findings.

The concrete pumping equipment available today is more advanced, reliable, and prolific than ever before. So why can’t I find one that can move this perfect mix I just created?

The factors that can affect concrete pumping are numerous, inter-related, and sometimes hidden, making the predicting of pumpability seem elusive. So how is the construction industry, which is becoming ever more cost conscious and filled with complicated and demanding concrete requirements, to deal with it on a more simplified level?

This presentation will discuss some of the over 50 factors that affect concrete pumping, the basics of how concrete pumping works, how mix designs can be adjusted to accommodate the application’s multiple requirements, and what can be done to help eliminate the jobsite problems that result in a finger pointing exercise and costly downtime.

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.

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.

View Description

---Close---

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.

View Description

---Close---

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.
