Effect Of Pismo Clams As Partial Fine And Coarse Aggregate Replacement On Workability And Compressive Strength Of Concrete, Alan Munoz Pille Jun 2024

Effect Of Pismo Clams As Partial Fine And Coarse Aggregate Replacement On Workability And Compressive Strength Of Concrete, Alan Munoz Pille

Construction Management

Concrete has been utilized for ages. Unfortunately, over the hundreds of years there has been little development in the applications of new aggregate materials. The world is moving towards a sustainable way of living and as a result seashells have come into the mix. Pismo Clams are a native species to San Luis Obispo County. This marine species has the possibility of becoming a partial aggregate replacement for fine and coarse aggregates in concrete. The results of prior studies indicate a possible application of seashell use in concrete. This paper evaluates the workability and compressive strength of concrete containing fine …

Electrical Design For Moringa Leaf Dryer, Jake Weiss Jun 2024

Electrical Design For Moringa Leaf Dryer, Jake Weiss

Construction Management

The objective of this project is to provide a methodology to the electrical scope of mechanical leaf dryers. This dryer was particularly designed for an off-grid farm in New Longoro, Ghana in which resources and materials are limited. The electrical system must be designed so that it works with motors, variable frequency drives, worm gears, and other materials that could be sourced in Ghana. The system should also draw minimal power so that remaining photovoltaic energy could be utilized on the farm. The system should be simplistic and repeatable for other farmers to utilize. By using both a numerical analysis …

Feasibility Of Implementing A Construction Project In An International Country, Kristina Poliseri Jun 2024

Feasibility Of Implementing A Construction Project In An International Country, Kristina Poliseri

Construction Management

This paper examines the execution of an international service project involving the construction of a complex system. It explores three distinct approaches assuming a fully designed system: building the system in the U.S. and shipping it internationally, having system pieces constructed entirely in the destination country prior to arrival for assembly, and developing a prototype in the U.S. followed by the construction of a full-scale system in the international country. Each method presents unique advantages and challenges. Building in the U.S. ensures high quality, advanced technology, and meeting tolerances, however, leads to significant fees, shipping costs, and logistical complications. Constructing …

Use Of Tempered Glass As A Potential Substitute For Coarse Aggregate In Concrete, Will Nethercutt Jun 2024

Use Of Tempered Glass As A Potential Substitute For Coarse Aggregate In Concrete, Will Nethercutt

Construction Management

Tempered glass poses issues for traditional glass recyclers, as the melting temperature is different from standard glass due to the tempering process that the glass is subjected to. This makes tempered glass more difficult to recycle and opens this material up as a potential for other methods of environmentally beneficial disposal. Tempered glass breaks into relatively consistent pieces that are more rectangular and granular than standard glass. Granular size is dependent on the thickness of the glass used and forms a relatively cubic shape. This size is similar to some of the material found in standard coarse aggregate for concrete …

Assessment Of Musculoskeletal Disorders (Msds) Risk During The Framing Of A 6' X 8' Wooden Shed Using Traditional Hammers, Maxwell R. Helfman Jun 2024

Assessment Of Musculoskeletal Disorders (Msds) Risk During The Framing Of A 6' X 8' Wooden Shed Using Traditional Hammers, Maxwell R. Helfman

Construction Management

Wood-framed construction will almost always use nails as a connector whether it be for different pieces of wall sections or connecting wall sections to the structure. Nails also act in Shear Walls in different nailing patterns to prevent the panel from splitting. Houses in modern times are usually nailed with nail guns, either with a cord or cordless, which reduces their exposure to Musculoskeletal disorders (MSDs). However, smaller jobs may opt to use traditional hammers instead of nail guns. This study aims to numerically quantify the forces and flexions one puts on the body when performing nailing tasks using a …

The Challenges Of Building A Mass Timber Single-Family Home: A Case Study, Avery Emma Onan

Construction Management

This case study explores the various challenges faced by those involved in the pre-construction and construction of a mass timber, single-family home in Central Texas. Using semi-structured interviews, a subcontractor, an owner, a manufacturer, and two construction managers were questioned about their specific challenges with the build. These challenges were solely related to the use of mass timber on the project. In recent years in the United States, mass timber has become an increasingly desired building material to use in a commercial and multi-family residential context. Due to limited information and builder inexperience using mass timber in a single-family homebuilding …

Evaluating Value Engineering Techniques Of California Contractors, Mason Alec Montoya Jun 2024

Evaluating Value Engineering Techniques Of California Contractors, Mason Alec Montoya

Construction Management

Value engineering plays a critical role in delivering the best possible project to an ownership team. Preconstruction teams across firms of all sizes perform value engineering studies to determine how project scopes can be changed to advance the construction schedule, reduce costs, and ensure the end user is satisfied with their building. To determine how California general contractors employ value engineering, I used a series of interview questions in a structured format to interview four professionals from different California general construction firms. The analysis and findings of my study provide insight into how familiar construction teams are with value engineering …

Thinking Styles In The Built Environment, Jaden A. Green Jun 2024

Thinking Styles In The Built Environment, Jaden A. Green

Construction Management

Effective communication in the built environment is crucial for project success, information relay, goal alignment, error prevention, and safety. Diverse parties, including general contractors, architects, engineers, and subcontractors, bring varying Thinking Styles to the table, as defined by Harrison and Bramson. These styles—Synthesist, Idealist, Pragmatist, Analyst, and Realist—impact collaboration and conflict within projects. This study aims to explore where thinking differs among these parties and the congruity of Thinking Styles within each group. Results of this study indicate a predominant Realist Thinking Style among general contractors and subcontractors with subcontractors equally leaning towards Analyst. Engineers, although expected to be Analysts, …

Drone Applications In Residential Construction, Leo Geiger Jun 2024

Drone Applications In Residential Construction, Leo Geiger

Construction Management

Drones, or unmanned aerial vehicles (UAVs), have revolutionized various industries since their creation, particularly in construction. Originally used for military and recreational purposes, drones began to find their place in construction in the early 2010s, primarily for surveying and mapping. While tons of research has been conducted on drones' capabilities in surveying, there is a gap in studies focusing on their applications for general contractors, particularly in large-scale developments. Five interviews were conducted, three with general contractors who have integrated drone technology into their teams and two drone companies that provide subcontracted drone services. Through these interviews, the primary applications …

Understanding The Behavior And Risk Tolerance Of Future Construction Industry Leaders, Mateo Daniel O'Sullivan Jun 2024

Understanding The Behavior And Risk Tolerance Of Future Construction Industry Leaders, Mateo Daniel O'Sullivan

Construction Management

A long persisting detriment to the construction industry is the impact of alcohol, substance abuse, and gambling throughout the field. Many workers fear the repercussions of missing work and push through smaller, manageable pain, leading to injuries and further pain as they age. This causes a heightened usage of opiates throughout the industry to stay at work without bothering your company. Additionally, many young project engineers are not used to the demand of long hours every week and look for vices to relieve stress. While there is plenty of data on the construction industry overall, this study aims to learn …
