Construction Clothing Development Project, Reed A. Kellar, Noah R. Maytum Jun 2025

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 …

Case Study: Cal Poly Housing Program (Cphp) - Student Housing Project At California Polytechnic University, San Luis Obispo, Aidan Michael Toole Mar 2025

Case Study: Cal Poly Housing Program (Cphp) - Student Housing Project At California Polytechnic University, San Luis Obispo, Aidan Michael Toole

Construction Management

Full volumetric modular construction is a building technique that involves the off-site prefabrication of three-dimensional modular units, which are later transported and assembled on-site. California Polytechnic State University in San Luis Obispo and general contractor, Whiting-Turner, are building new on-campus student housing by utilizing full volumetric modular construction techniques. The buildings will be produced in modules that, when put together, reflect the identical design and intent of a site-built building. This paper will analyze the effectiveness of modular construction on a large-scale project and look at the project cost, schedule, and waste impacts from choosing this approach. The main driver …

Structural Analysis And Design Methodologies Of Roller Coasters, Benjamin Komar Jan 2025

Structural Analysis And Design Methodologies Of Roller Coasters, Benjamin Komar

Williams Honors College, Honors Research Projects

This project explores the structural analysis behind the design of roller coaster tracks and supports as practiced by modern engineers. It also examines various roller coaster design methods currently in use. This research will be used to craft a detailed explanation of the roller coaster design process. Additionally, a 3D model of a roller coaster was developed based on the researched design procedures, featuring three track sections with different loading conditions to create a supporting structure for 2D truss analysis. The results of the truss analysis were then compared to those obtained using RISA-3D, a finite element structural design software.

Stability Of Two-Class Armour Berm Breakwaters: An Experimental Study, Mohammed Al-Ogaili, Amir Etemad-Shahidi, Nick Cartwright, Sigurdur Sigurdarson

Research outputs 2022 to 2026

The recession of a berm breakwater is a key parameter in ensuring its stability, and functionality, to protect coastal areas against wave impacts. Consequently, consideration of the expected recession in structural design is required to ensure the required objectives of the structure. In this study, physical model laboratory experiments were conducted to measure the recession of two-class armour berm breakwaters in response to varying sea state conditions (wave height, wave period, storm duration, and water depth at the structure's toe) and geometrical parameters (berm elevation from still water level, berm width, and rock size). A total of 110 tests were …

Building Artificial Reefs From Recycled Construction Materials: A Feasibility Study, Nicholas H. Lew Mar 2023

Building Artificial Reefs From Recycled Construction Materials: A Feasibility Study, Nicholas H. Lew

Construction Management

Naturally occurring reefs are some of the world’s most biologically diverse ecosystems formed by jagged rocks tucked slightly below sea level. In recent years global warming began to pose a major threat to many reef habitats. Most relevant is the increase in surface seawater temperatures that cause coral to bleach, taking away major food sources for larger marine species. Researchers have combated this by deploying artificial reefs in substitution for naturally formed limestone rock formations in order to promote the expansion of coastal habitats. This project specifically aims to utilize construction waste towards the production of artificial reefs, effectively upcycling …
