Case Study: Mitigating Schedule Impacts From Oshpd Regulations On Medical Equipment, Peter K. Lee Dec 2017

Case Study: Mitigating Schedule Impacts From Oshpd Regulations On Medical Equipment, Peter K. Lee

Construction Management

The vast majority of healthcare construction projects in the state of California work with OSHPD—Office of Statewide Health Planning and Development—to meet California’s Hospital Seismic Safety Law. While meeting the state’s Hospital Seismic Safety Law is important and even critical, working with OSHPD’s stringent regulations does imply additional concerns to be addressed by the project team. One concern regards the approval of bigger medical equipment and its impact on the overall construction schedule. This paper examines the factors that contribute to delays in the construction schedule, responsible parties for the delay, and responsibilities of each ...


Impacts Of Rail Transit Investments On Demographics And Land Use: 1990-2010, Aubrey Trinidad Aug 2017

Impacts Of Rail Transit Investments On Demographics And Land Use: 1990-2010, Aubrey Trinidad

All Theses

This paper studies the changes in land use and population characteristics around station areas following the building of rail transit stations in 14 major cities in the United States from 1990 to 2010. It answers the question: how have investments in US rail transit made since the 1990s affected land use and demographics? It also looks at the specific effects of investments on population density, race, and ethnicity, means of transportation, median housing value, median household income, vehicle access share, occupations, and land use represented by the share of multifamily versus single-family housing. Using block group level US census data ...


Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband Jun 2017

Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband

Architectural Engineering

Stochastic Subspace Identification is a field of applied mathematics that takes collected experimental time-history data and gives out information about the system that produced the data. SSI is typically used in control analysis but here we apply the methods to the modal analysis of structures. This senior project didn’t involve theory - instead much of the work was in research behind how Subspace Identification works, implementing the algorithm in MATLAB, and applying the program to shake table data to validate the program. In other words, building the framework to make SSI a usable tool and practical learning experience for other ...


Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson Jun 2017

Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

The first aspect of this project ...


Implementing Net Zero Energy Into The Construction Innovations Center, Marlo Arleen Castro Jun 2017

Implementing Net Zero Energy Into The Construction Innovations Center, Marlo Arleen Castro

Construction Management

As the environmental status of our planet declines, it is becoming more and more important for the construction industry to adapt. Leadership in Energy and Environmental Design (LEED) is becoming an unspoken requirement for all new and tenant improvement construction, and now, with the goal of Net Zero Energy (NZE) for all new commercial buildings by 2030, NZE is becoming the way of the future. As of late, California Polytechnic State University in San Luis Obispo (Cal Poly) has made grand efforts to retrofit several of the older buildings on its campus in order to achieve LEED certification. One of ...


Modular House Revival, Kevin Chiang, Spencer Dilley, Sarah Dowthwaite, Trevor Houghton, Ryan Lefebvre, Michele Leung, Cameron Lober, Chris Martinez, Katie Mayer May 2017

Modular House Revival, Kevin Chiang, Spencer Dilley, Sarah Dowthwaite, Trevor Houghton, Ryan Lefebvre, Michele Leung, Cameron Lober, Chris Martinez, Katie Mayer

Architectural Engineering

The Modular House, located in Poly Canyon, has seen extensive damage since the last caretaker left nearly ten years ago. To prevent further damage and improve the safety and appeal of the structure, we are proposing a renovation of the existing building that removes the existing cladding and partitions. By the end of Spring Quarter 2017, the Modular House will have a guardrail system replacing the wood paneling on the walls and a new steel composite deck to replace the current flooring system. The structural steel framing system will remain as is.


Effect Of Hydration And Confinement On Micro-Structure Of Calcium-Silicate-Hydrate Gels, Harish Kumar Gadde Jan 2017

Effect Of Hydration And Confinement On Micro-Structure Of Calcium-Silicate-Hydrate Gels, Harish Kumar Gadde

Civil Engineering Graduate Theses & Dissertations

Calcium-silicate-hydrate(C-S-H) gel is a primary nano-crystalline phase present in hydrated Ordinary Portland Cement (OPC) responsible for its strength and creep behavior. Our reliance on cement for infrastructure is global, and there is a need to improve infrastructure life-times. A way forward is to engineer the cement with more durability and long-term strength. The main purpose of this research is to quantify the micro-structure of C-S-H to see if cement can be engineered at various length scales to improve long-term behavior by spatial arrangement. We investigate the micro-structure evolution of C-S-H in cement as a function of hydration time and ...


Energy Performance Anlaysis Of Transparent Wood Composite-Based Glazing Systems In Commerical Buildings, Joseph Hoberg Arehart Jan 2017

Energy Performance Anlaysis Of Transparent Wood Composite-Based Glazing Systems In Commerical Buildings, Joseph Hoberg Arehart

Civil Engineering Graduate Theses & Dissertations

Transparent wood composites (TWCs) have 15% the thermal conductivity of silicon-based glass and can be used in alternative glazing systems. Single-paned and double-paned TWC based window assemblies were developed for implementation in commercial reference buildings of three vintages (Pre-1980, Post-1980, and Post-2004) located in 15 climate zones. Energy simulations were performed for baseline buildings and compared against buildings with TWC based glazing systems in place of traditional glass based glazing. In addition, a cost analysis was performed for lab-scale production of TWCs. Results showed that buildings with TWC based windows reduced space conditioning by up to 33.3%. Commercial buildings ...


Competition And Price Analysis Of Indefinite Delivery Indefinite Quantity Contracts For Construction, Matthew Scott Stanford Jan 2017

Competition And Price Analysis Of Indefinite Delivery Indefinite Quantity Contracts For Construction, Matthew Scott Stanford

Civil Engineering Graduate Theses & Dissertations

Indefinite delivery-indefinite quantity (IDIQ) construction contracts use an overarching master contract between an owner and contractor for multiple projects over a specified time period. The practice is widespread in the U.S. federal government but its efficacy has been the subject of relatively few studies. This dissertation offers a state-of-practice review of IDIQ construction contracting as well as an empirical analysis of the competition and cost implications of using IDIQ contracts. Content analysis of 90 federal requests for proposal reveals IDIQ contracting use for a wide range of facility types and construction services. Findings suggest that IDIQ contracts reflect the ...


Extending Time Series Forecasting Methods Using Functional Principal Components Analysis, Isaac Michael Wagner-Muns Jan 2017

Extending Time Series Forecasting Methods Using Functional Principal Components Analysis, Isaac Michael Wagner-Muns

Masters Theses

"Traffic volume forecasts are used by many transportation analysis and management systems to better characterize and react to fluctuating traffic patterns. Most current forecasting methods do not take advantage of the underlying functional characteristics of the time series to make predictions. This paper presents a methodology that uses Functional Principal Components Analysis (FPCA) to create smooth and differentiable daily traffic forecasts. The methodology is validated with a data set of 1,813 days of 15 minute aggregated traffic volume time series. Both the FPCA based forecasts and the associated prediction intervals outperform traditional Seasonal Autoregressive Integrated Moving Average (SARIMA) based ...
