Innovative teaching methods must be studied and implemented to optimize student learning and prepare future generations for complex challenges. Dr. Keith Hjelmstad, a professor at Arizona State University, developed such an approach, “The Mechanics Project,” and has implemented it in foundational engineering mechanics courses. Although course instructors have used traditional “lecture and read” approaches for generations, the world is changing, requiring a modified policy. In this thesis, I research, discuss, and analyze the positive effects of The Mechanics Project for civil engineering students based on its fundamental principles.
ML algorithms for classification of cementitious phases are found to require only the intensities of Ca, Si, and Al as inputs to generate accurate predictions for more homogeneous cement pastes. When applied to more complex UHP systems, the overlapping chemical intensities in the three dominant phases – Ultra High Stiffness (UHS), unreacted cementitious replacements, and clinker – led to ML models misidentifying these three phases. Similarly, a reduced amount of data available on the hard and stiff UHS phases prevents accurate ML regression predictions of the microstructural phase stiffness using only chemical information. The use of generic virtual two-phase microstructures coupled with finite element analysis is also adopted to train MLs to predict composite mechanical properties. This approach applied to three different representations of composite materials produces accurate predictions, thus providing an avenue for image-based microstructural characterization of multi-phase composites such UHP binders. This thesis provides insights into the microstructure of the complex, heterogeneous UHP binders and the utilization of big-data methods such as ML to predict their properties. These results are expected to provide means for rational, first-principles design of UHP mixtures.
Overall, this project report provides due diligence for a proposed development project, Bella Vida Estates, designed by Red Rock Engineering. This proposed project is located in the southwest portion of the City of Phoenix, in the Laveen Village community.
Bella Vida Estates is a proposed 560-acre mixed-use development whose composition includes single family residential, commercial, recreational park and greenspace, a preparatory charter school, and water storage and wastewater treatment facilities. The subject property is confined east of the new Loop 202 – South Mountain Freeway Extension, south of W. Dobbins Road, north of W. Elliot Road, and west of S. 51st Avenue.
The Due Diligence report is comprised of relevant information needed to develop these parcels of land, including a Property Overview, Land Development Plan, Development Considerations, Sustainability and Value Add components, and Costs.
To provide a more comprehensive due diligence package for the proposed project, street improvement quantities were estimated and then presented via a Construction Documents Exhibit and an Opinion of Probable Costs document.
The Construction Documents Exhibit was created according to City of Phoenix Standards using AutoCAD Civil 3D. The exhibit includes four sheets: Cover Sheet, Exhibit Sheet, Cross Sections, and Appendix. The purpose of this exhibit is to provide a visual representation of the streets to be improved upon, with proper hatching (based on type of cross section), dimensioning, and annotations to aid in presentation.
The Opinion of Probable Costs tabulates Onsite Development costs, which includes Paving, utilities in the form of Water, Sewer, and Storm, Earthwork/Grading, and Lump Sum costs. In addition to the onsite costs, Contingency, General Conditions, General Contractor Fee, and Taxes are included to provide a comprehensive overview of estimated costs.
Red Rock Engineering is excited to propose this promising, sustainable development as a place of residence, commerce, and recreation to the residents of the Laveen Village community.
This podcast focused on the experience of women in the field of STEM and more specifically civil engineering. The episodes will explore three main topics surrounding women in the workforce: how women navigate and succeed in a workforce with a predominantly male presence, whether or not women experience “impostor syndrome,” and how to deal with being undermined in the workforce. Also available on Spotify!
