Hydraulic Balsa Wood Rising Bridge, Kaitlyn Greenfield
Hydraulic Balsa Wood Rising Bridge, Kaitlyn Greenfield
All Undergraduate Projects
What is the solution to allowing tall vessels to navigate past a vehicle bridge that is less than 10 [ft] above the water? To answer this question, a balsa wood bridge was designed, constructed, and tested. The bridge needed to articulate by mechanical means, allow for travel through the bridge, and be able to withstand ample force while the main structure only being constructed of balsa wood and glue. The project was analyzed in sections. These sections include: the bridge structure and its members, the hydraulic lift, and the pins needed for the bridge and hydraulic lift to operate. The …

Hydronic Service Valve Product Development, Mark Hunsaker
Construction Management
Since the inception of modern mechanical and HVAC systems, maintenance and repairs have been prevalent in both contracting and facility operations. The average life of HVAC equipment is fractional compared to the life of buildings as construction technologies improve. Traditionally, the serviceability of heating and cooling equipment has entailed the significant amounts of labor and materials to disruptively drain or freeze hydronic systems in order to cut in means of bypassing the main system, swapping out equipment, or repair. The intent of this project is to explore alternative methods to forgo the aforementioned negative impacts of service and to improve …
Cal Poly Engineering East – Building 20, A Critical Analysis Of Mechanical Needs And Distribution Of Mechanical Resources, Rhea Bae
Construction Management
Older buildings on the Cal Poly campus need renovation, particularly with the heating, ventilation, air-conditioning (addressed as HVAC) systems in the classrooms. The HVAC units within the old buildings are obsolete, inefficient, and are most likely due for replacement. The Engineering East building, also known as Building 20, is an example of a campus building that requires a quality HVAC system. By upgrading the HVAC, the building conditions can be positively enhanced through better cooling and ventilation, allowing students in the labs and classrooms to have a better experience within the building. This paper details the methodology behind installing a …
Ghana Clean Water Initiative – Risk Management, Mason Nolan
Ghana Clean Water Initiative – Risk Management, Mason Nolan
Construction Management
In August of 2019 several Cal Poly Students will be traveling to a remote fishing village located off of Lake Volta in Ghana. This project is being completed by Cal Poly's MCAA chapter alongside the NECA chapter. These students will be constructing a community center, a water filtration system, and ice making and refrigeration facilities. The project will rely heavily on solar power as there is no grid in the village the project is taking place in. This project inherently has many risks associated with it and needs a risk management plan to combat these risks. The three ways these …
The Setty Family Foundation 2018 Ashrae Applied Engineering Competition, Joshua Heath
The Setty Family Foundation 2018 Ashrae Applied Engineering Competition, Joshua Heath
Construction Management
The Setty Family Applied Engineering Challenge tasked my project group with designing a temporary shelter specifically for refugees in Eastern Europe to be used by governments, municipalities, and humanitarian agencies that is cost effective, portable, sustainable, and provides all necessary domestic needs. After months of research and design, we have developed the PolyShelter ; an eight-person structure erected to provide comfortability and safety to those in need. PolyShelter is designed to withstand the harshest of climates, provide exceptional insulation, and incorporate a rainwater collection system sufficient enough to support each unit. PolyShelter proves itself to be an economically viable solution …
An Analysis Of The Benefits In Estimating At Different Pipe Union Labor Rates, A.J. Chamorro
An Analysis Of The Benefits In Estimating At Different Pipe Union Labor Rates, A.J. Chamorro
Construction Management
This paper is an analysis of the costs and benefits of estimating at different union labor rates, based on the location of the project and which jurisdiction the project falls in. The basis of the research is a case study of a Bay Area mechanical contractor (Contractor X) which previously estimated at a single labor rate, and recently developed variable estimating. Through that case study, best practices are developed for union pipe trade estimating. The results of the case study show that estimating protocol should be determined on a project by project basis, and company resources and manpower have to …
