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.

This presentation will cover the basics of common supplementary materials used in concrete. Common applications, comparisons of their properties in plastic and hardened concrete, as well as the outlook of their future use will all be covered in the presentation.
