The Utilization Of Biodiesel In Commercial Equipment In Construction, Ryan Bustos
Construction Management
The utilization of heavy machinery is essential to the success of all construction projects, but the dependence of traditional diesel fuel contributes significantly to the carbon footprint of the industry. Biodiesel presents a cleaner, more sustainable alternative, yet its adoption across construction sites remains limited. This paper will examine the current use of biodiesel by contractors and explore key barriers preventing its implementation. A series of interviews with industry professionals responsible for fuel and equipment management were conducted to collect various insights and perspectives on the alternative fuel. This study focuses on identifying obstacles such as biodiesel cost, availability, compatibility, …

Concrete Patio Demolition And Construction, Tyler Nielsen
Construction Management
A 6.25 cubic yard unreinforced concrete patio was constructed for the non-profit organization. This project included three phases: concrete slab demolition, grading and formwork, and concrete pouring. Each phase was estimated and then received owner approval prior to execution. The demolition phase involved obtaining city permits for a roll-off container for debris removal. This phase also included two days of work with over 10 demolition crew members, who were given the required training and equipment to ensure safety and productivity. The following weeks included grading and setting up formwork. Once the grade was complete, the formwork was laid out and …

El Chorro Park Lumber Rack & Trailhead Kiosk Project, Nolan Christopher Gumm, Marvin Michael Garliepp
Construction Management
The EL Chorro Park Lumber Rack and Kiosk project was a collaboration with San Luis Obispo County Parks and Recreation. Located at El Chorro Regional Park in San Luis Obispo, California, the project involved building a 12-foot-long, 6-foot-wide, and 8-foot-tall lumber rack and reconstructing an outdated trailhead kiosk. The lumber rack addressed the need for organized storage of wood and metal pipes, while the kiosk was rebuilt to better serve park visitors. Recycled sheet metal from the client was used for the roof, and local suppliers were selected to support sustainability efforts. Funded entirely by a government entity, there were …

Designing Augmented Reality (Ar) Simulations For Construction Scheduling Education: A Process-Based Approach, Luke Sutherland
Construction Management
This paper presents the design and implementation of an augmented reality (AR) testing protocol developed to assess construction students' planning, sequencing, and real-time decision-making skills. Using Microsoft HoloLens, the simulation exposed students to realistic jobsite scenarios that required them to interpret plans, develop task sequences, and respond to evolving conditions in the field. The protocol was conducted with over 30 construction management students at California Polytechnic State University, San Luis Obispo, and included three progressively complex scenarios focused on underground utilities, concrete formwork delays, and overhead MEP coordination issues. Data was captured through AR interaction logs, time tracking, instructor observation, …

Farm Furniture - City Farm Slo, Aiden Blackburn, Antonio Nunez
Construction Management
Our senior project was to build 4 picnic tables, 6 picnic benches, 2 vegetable tables, and 1 hexagon shaped table for the City Farm SLO in San Luis Obispo, CA. We were grateful to help a local farm who focuses on education in the community and sustainable agricultural practices. We first estimated the project and created a preliminary schedule. This project lasted from mid-April to mid-June. The first step in the process was to estimate the cost and develop a preliminary schedule. The process for constructing the different build types was relatively similar: acquire materials, cut to size, assemble, sand, …

Designing Augmented Reality (Ar) Simulations For Construction Scheduling Education: A Process-Based Approach, Spencer B. Gardner
Construction Management
Construction students often understand what’s being built, but not how it gets built. The process, which is timing, sequencing, adapting to real-world issues is harder to teach with traditional tools like plan sets and Gantt charts. To close that gap, this study explores how Augmented Reality (AR), using Microsoft HoloLens, can bring jobsite logic into the classroom. We developed three AR simulations, each with increasing complexity, to give students hands-on experience with real-world scheduling and coordination problems. The scenarios ranged from basic utility sequencing to adjusting for delays and correcting out-of-sequence installations. Students started with written planning, then moved into …

Case Study On Using Soil Nails In Unstable Substrates, Joseph Hass
Construction Management
Soil nailing is becoming a popular method in construction projects to anchor retaining walls into soil. To maximize installation success rates and minimize pullout failure during testing, this case study examines efficient techniques and installation protocols for soil nails in unstable substrates through research and studying an active construction site utilizing soil nails. In geotechnical engineering, unstable soil conditions present serious difficulties that frequently result in delays, cost overruns, and compromised structural integrity. This study determines the main elements affecting nail performance by carefully examining field data, installation trials, and performance testing. Using real life experience and in-depth research of …

Construction Clothing Development Project, Reed A. Kellar, Noah R. Maytum
Construction Management
Relative to other industries, the construction market is slow to innovate. One clear example of this is in the clothing worn by its workers. Over the past 100 years, construction clothing and top brands have remained largely similar, even as workwear has begun marketing to larger, non-construction audiences. Construction clothing has become increasingly fashionable in popular culture, and we see this as an opportunity. To adapt to a modern world, this entrepreneurial project seeks to research which areas of construction clothing are lacking according to those in the industry and use this data to create a competitive product/brand that capitalizes …

California Polytechnic State University, San Luis Obispo
A Review Of Work-Life Balance Among Recent Cal Poly Graduates, Max Murphy
Construction Management
Work-life balance has been a heavily debated topic in the construction industry, especially post-COVID. Due the popularization of the topic as well as the introduction of “hybrid” work schedules among multiple industries the idea of work-life balance within the construction industry has become prevalent. This paper aims to gather data about work-life balance and stress among the construction management industry. A survey was distributed to recently graduated construction management students from California Polytechnic State University – San Luis Obispo to gather quantitative data regarding work-life balance, commuting, work hours, stress, and mental health.
