Quality Assurance And Quality Control For Reinforced Concrete Inspections, Calvin O. Walters Jr.
Quality Assurance And Quality Control For Reinforced Concrete Inspections, Calvin O. Walters Jr.
Publications and Research
Ensuring the safety and longevity of structures is paramount in concrete construction projects. Cases like the Big Dig ceiling collapse, which occurred on July 10, 2006, when a concrete ceiling panel measuring 20' x 40' and debris weighing 26 short tons (52,000 lb) fell within Boston's Fort Point Channel Tunnel, underscore this importance (Wald, M. L., 2007). Quality Assurance (QA) and Quality Control (QC) are crucial in mitigating such risks. QA ensures that materials and methods meet predetermined performance, design, and reliability standards specified in contracts and customer arrangements. On the other hand, QC is a strategic process businesses use …
Bim Coordination Post Pandemic, Zachary Marshall
Bim Coordination Post Pandemic, Zachary Marshall
Honors Scholar Theses
The goal of this thesis is to utilize previous research done on virtual meetings and build upon it by conducting new research on the successes and failures of current virtual BIM meetings. This paper starts with a literature review looking into Building Information Modeling (BIM) Coordination and the effects the COVID-19 pandemic has had on the BIM meetings. BIM meetings started to shift virtual due to the nature of the pandemic and this has had effects on the performance and structure of the coordination. This knowledge was then expanded on by looking at virtual BIM meeting case studies. Interviews were …

Nebraska Department of Transportation: Research Reports
To protect waterways adjacent to construction projects with disturbed land, a 50 ft (15 m) vegetated buffer or equivalent sediment controls are required. However, there is little guidance on the effectiveness of vegetated buffers in removing sediment or how sediment barriers can aid shorter buffers or replace buffers. A modeling methodology was developed and used to determine the performance of 11,664 50 ft (15 m) vegetated buffer configurations with Nebraska conditions; sediment capture averaged 92.6% and ranged from 18.5% to 99.5%. To determine the performance of Nebraska Department of Transportation standard and modified sediment barrier installations, a large-scale testing methodology …
