San Luis Obispo Botanical Garden Bridge Rebuild
Get PDFThis paper will outline the process of designing, deconstructing, and reconstructing a utility bridge at the San Luis Obispo Botanical Garden. The San Luis Obispo Botanical Garden’s entrance was recently changed deeper into the property. The old entrance was at the front and was home to a bridge utilized by staff, volunteers, and visitors alike. This project’s goal was to rebuild the utility bridge so that it could be used by the facilities staff and volunteers when working on property. There was one student involved in this project who acted as the designer, performed the preconstruction work, and constructed the bridge as well. The design and preconstruction of the bridge was done prior to the plans being approved and procuring the material. The deconstruction and construction phase were focused on the logistics of building the bridge and ensuring it was done on-time, within budget, and to plan. The design phase began by coordinating a schematic design with the garden’s executive team and planning a realistic design that would be shown with details and specifications. This paper will cover the entire process of the project from before and after
Cal Poly Campus Safety: Policy Proposal
Get PDFAs described in this project, the California Polytechnic State University, San Luis Obispo is in need of improving the campus’s sense of safety and safety features. With an increasing student population and increasing dangers, the importance of safety for all is becoming evident. The COVID-19 pandemic has taught us that it is essential to have proper safety features and preventative measures in place to keep the student and faculty population safe. The project’s goal is to produce safety recommendations that could be used to amend the existing 2035 Campus Master Plan. Currently, safety is not a topic extensively covered in the Master Plan and lacks proper discussion. The project focuses on safety policies, goals, and objectives that would further promote public safety and general welfare
Santa Margarita Watershed Sanitary Survey Update for 2021
Get PDFThe Watershed Sanitary Survey update evaluates the water quality of a groundwater aquifer utilized by the community of Santa Margarita as a municipal water source through Well No. 4. It was last conducted in 2011. The Watershed Sanitary Survey is a regulatory document for the compliance of Santa Margarita’s water system with the Surface Water Treatment Rule (SWTR), aimed at protecting the public from any sources of drinking water contamination. The unprecedented level of drought occurring over the last five years could spell unknown changes to the water quality of the aquifer, possibly increasing the concentration of pollutants. This poses new risks to public health and sanitation that could compromise the use of Well No. 4. Water quality was evaluated by identifying, examining and summarizing constituents of concern and if they exceeded allowable regulatory levels. Rainfall and well depths were summarized to determine the severity of drought conditions and to compare with water quality metrics to determine any possible patterns. Data was collected from 2011 to 2020, following the last published survey in 2011. Despite the lack of precipitation, water quality and well depths of Well No. 4 remained largely unchanged. Bacteriological results indicated no presence of E. Coli, with only four detections of naturally occurring total coliforms. Results for metals, turbidity, minerals, surfactants, nitrates and nitrites were all under regulatory limits. Well depths did not reach critical thresholds despite lack of recharge from precipitation. Over the last 10 years, Well No. 4 met all water quality standards even in critical drought conditions. Its groundwater continues to be of excellent quality and can continued to be used as a municipal water supply as long as current disinfection practices remain in place
Harnessing Your Feminist Rage: A Multimedia Assignment for Upper-Level Courses
Get PDFHarnessing Your Feminist Rage introduces a three-part multimedia assignment that encourages students to think critically about feminist anger, particularly as refracted through social media. First, students introduce and analyze a media text or phenomenon that made them angry and reflect upon that anger. Then, using whichever online medium they choose, students call out the offender and express their anger to the audience of their choice in order to meet a specific goal. Finally, students reflect on their expression of anger and their experience creating their response. Overall, the goal is for students to combine their knowledge of feminist theories and their interests in social justice and popular culture to explore the productive potential of feminist rage and engage critically with digital accountability practices that are so often maligned as cancel culture
Construction of Modular Concrete Footings for Use in Cal Poly’s High Bay Laboratory
Get PDFThis project-based senior project had the end goal of creating two concrete modular foundations that can be used in the High Bay Laboratory for testing procedures. The concrete modular blocks are 6’ long by 3’ wide, and 1.5’ tall. The foundations each held 100 embeds. Each embed serves as an anchor point for various attachments for testing purposes. This was an interdisciplinary project amongst two CM students and one ARCE student. The ARCE student was responsible for the design of the blocks, encompassing the formwork and the rebar. The CM students were responsible for estimating, scheduling, and the construction of the blocks. Construction of the two footings involved the fabrication of plywood box forms that eventually held the rebar cage and various embeds. Additional reinforcement was needed on the outside of the box forms to allow for the forms to be strong enough to withstand the outward pressure of the wet concrete as it was poured into each of the boxes. The completed modular foundations were stripped of the plywood formwork and inverted to be the proper orientation when bolted into the High Bay Lab floor. *This material is based upon work supported by the National Science Foundation under Grant No. 2019198.

Biodegradation of Methyl Tert-Butyl Ether and Tert-Butyl Alcohol Using Bioaugmentation with BiOWiSH® Aqua
Get PDFAqua, a commercial product manufactured by BiOWiSH® Technologies, was utilized in this research to study its effectiveness to biodegrade methyl tert-butyl ether (MTBE) and tert-butyl alcohol (TBA). Microcosms containing varying concentrations of MTBE and TBA as well as a growth media and mineral salt solution were examined. Analytical instrumentation used in this study included the use of a gas chromatograph-mass spectrometer (GC/MS) to determine concentrations of MTBE and TBA and a spectrophotometer to extrapolate approximate active biomass concentrations in each experiment. Four different environmental conditions were tested for both MTBE and TBA. The environmental conditions tested for each contaminant included: biodegradation under aerobic conditions, biodegradation under anaerobic conditions, biodegradation under denitrifying conditions, and biodegradation under aerobic conditions with glucose present.
This study concluded that there is potential for degradation of MTBE and TBA using Aqua under the conditions tested. Maximum MTBE biodegradation was observed under aerobic conditions which yielded a first order rate constant of 0.019/hour and a 99.8 percent decrease in MTBE over 14 days. Maximum TBA biodegradation was observed under aerobic conditions with glucose present which yielded a first rate order constant of 0.009/hour and a 95.03 percent decrease in TBA concentrations over 14 days. It is presumed that under both conditions a monooxygenase enzymatic reaction involving Cytochrome P-450 aids in breaking down both MTBE and TBA. However, the results presented are indicative of biodegradation under lab conditions with little to no interference. Further research is needed to determine the effectiveness of Aqua utilizing groundwater or soil samples from MTBE or TBA contaminated sites in order to truly analyze Aqua’s potential to be used as a bioaugmentation product in real world applications
