Reducing Carbon Emissions With Returned Concrete, John M. Maxwell Jr.
Reducing Carbon Emissions With Returned Concrete, John M. Maxwell Jr.
Construction Management
The concrete industry is one of the most energy-intensive sectors of construction. Specifically, the cement production aspect is the most energy intensive, and produces the most carbon emissions. Concrete, a material ubiquitous with nearly every facet of construction; certain types of structures are composed of nearly all concrete. Production of cement is one of the biggest contributors to emissions within the industry. There have been initiatives to reduce or offset emissions from this process, through things like carbon capture, and the purchase of carbon or emissions credits. The objective of this paper was to investigate a new method of carbon …

The Impact Of Disc In Construction Dialogue, Michelle W. Li
Construction Management
Personality tests look to categorize individuals based on their values, identity, psychological traits, and/or perspectives. The DISC (dominance, influential, steady, complaint) assessment is one of the major personality tests. Multiple industries like healthcare and sales have utilized DISC to foster better overall communication from work relations and positive success. Construction management (CM) is a similar industry with heavy emphasis on influence and focus. Utilizing DISC in the construction industry can achieve similar effects to the healthcare and sales industry. To analyze the potential effectiveness of DISC in the construction industry, a survey was distributed to one class of CM majors …

Efficacy Of Passive Ventilation With High Exhaust Demands: A Case Study Of Cal Poly Sst, Siddarth Bokka
Efficacy Of Passive Ventilation With High Exhaust Demands: A Case Study Of Cal Poly Sst, Siddarth Bokka
Construction Management
The Simpson Strong Tie Demonstration Laboratory serves as a multipurpose space allowing students at the College of Architecture and Environmental Design at California Polytechnic State University to build full scale construction projects. The building features a material storage area, a high bay for construction of full-scale projects, and a mezzanine level that houses digital fabrication equipment. However, the building was never designed to house the specific equipment currently installed on the mezzanine and ventilate the exhaust fumes from them. Rather, the building relies on passive natural ventilation that is likely ineffective at properly exhausting hazardous fumes, resulting in complaints from …

Lemur Enclosure, Joshua Mancio, Justin Krietzberg
Construction Management
Zoo-to-You, a local wildlife conservation zoo, proposed a project to construct a new shelter for their lemurs due to the inadequacy of protection for extreme heat or cold weather of their previous enclosure. With three lemurs in residence, the zoo sought to create a spacious and insulated shelter that would provide protection from the elements while allowing connectivity to the adjacent enclosures. Situated amidst two existing circular cages with a gap in between, the project presented unique site conditions on a concrete slab. The scope of the project encompassed estimating, design, material procurement, build-out, and owner turnover, with the objective …
Effects Of The 2022 California Building Energy Efficiency Standards On New Construction In San Luis Obispo County, Christopher Hoefer
Effects Of The 2022 California Building Energy Efficiency Standards On New Construction In San Luis Obispo County, Christopher Hoefer
Construction Management
California released the first Building Efficiency Standards, or Energy Code, in 1976 and has updated them every three years. These standards aim at limiting the amount of energy use and greenhouse gas emissions by buildings in the state. California claims that these standards have saved consumers billions on utility bills, but there is limited information on the upfront impact the Efficiency Standards have had on new construction. This study sought to evaluate the impact that the 2022 California Building Energy Efficiency Standards had on new construction in San Luis Obispo County. Interviews were conducted with local specialty contractors in order …

Paso Robles Police Department Shooting Range Stairs, Emily Ann Andres
Paso Robles Police Department Shooting Range Stairs, Emily Ann Andres
Construction Management
The Paso Robles Police Department has a shooting range located just outside the Paso Robles Airport. The range is a newer facility that is used for training by the Paso Robles Police, as well as departments from surrounding cities. The flagpole for the range, located at the top of the hill, was inaccessible due to the brush overgrowth, gopher holes, and uneven terrain. Thus, the department needed a new staircase to improve accessibility to the flagpole so the red flag can be flown while the shooting range is in use. With many neighboring facilities, such as the remote-control plane club, …
