Description
The construction industry has been growing over the past few years, but it is facing numerous challenges, related to craft labor availability and declining productivity. At the same time, the industry has benefited from computational advancements by leveraging the use of Building Information Modeling (BIM) to create information rich 3D models to enhance the planning, designing, and construction of projects. Augmented Reality (AR) is one technology that could further leverage BIM, especially on the construction site. This research looks at the human performance attributes enabled using AR as the main information delivery tool in the various stages of construction. The results suggest that using AR for information delivery can enhance labor productivity and enable untrained personnel to complete key construction tasks. However, its usability decreases when higher accuracy levels are required. This work contributes to the body of knowledge by empirically testing and validating the performance effects of using AR during construction tasks and highlights the limitations of current generation AR technology related to the construction industry. This work serves as foundation of future industry-based AR applications and research into potential AR implementations.

Description
The Vietnam Construction Industry (VCI) has been facing risks that cause delays, budget overrun, and low customer satisfaction that required continuously research efforts to manage them. This research assesses the current conditions of the VCI in terms of performance, common risks, and success factors; and explores the potential of using the Best Value Approach (BVA), an innovative procurement and project management technology, to improve overall VCI performance. VCI risk factors were presented in an analysis of the data collected from a survey that include the 23 common risk factors that cause non-performance in construction projects in developing countries. The factors were consolidated from an extensive literature reviews, and inputs were solicited from 103 construction practitioners in Vietnam. The study reveals the top five risk factors as the bureaucratic administrative system, financial difficulties of owner, slow payment of completed works, poor contractor performance, financial difficulties of contractor. Factor analysis explored the correlations among the risks and yielded four outcomes – Lack of Site and Legal Information, Lack of Capable Managers, Poor Deliverables Quality, and Owner’s Financial Incapability. VCI success factors were revealed from a survey that is adopted from 23 Critical Success Factors (CSFs) related to common construction risks, found through extensive literature reviews, and inputs were solicited from 101 VCI participants. The experts ranked those CSFs with respect to impact to project success. The study reveals the top impactful CSFs such as all project parties clearly understand their responsibilities, more serious consideration during contractor selection stage, test contractors’ experience and competency through successful projects in the past. Factor analysis was conducted to explore the principal success factor groupings and yielded four outcomes – Improving Management Capability, Adequate Pre-Planning, Stakeholders’ Management, and Performance-based Procurement. An analysis from six industry experts determined how current VCI conditions, namely risk and success factors, are related to BVA. Sixteen BVA success principles were identified and ranked based on their perceived impact to project performance by an industry survey with 98 VCI practitioners. The results show high agreement rate with all sixteen BVA principles. The majority of participants agreed that BVA would improve project performance and were interested in learning more about BVA. The results encourage further BVA testing and education in the VCI.

Description
As construction and building methods advance so should their focus on reconstruction post-natural disasters. For the past 50 years there has been an average of 6.2 hurricanes making landfall, and several recent unfortunate occurrences in the past year that have caused immeasurable damage and taken priceless lives (Chris Landsea 2017). Damages could have been significantly reduced to residential homes and lives saved if proper, hurricane-resistant construction was used. It is important to continue advancement in efficient planning and reconstructive methods to restore individuals into their homes and ensure their safety in the future. Utilizing tested resilient building methods may increase construction costs but has a visible payoff through mitigation of economic losses in the future. This can also help develop response and mitigation plans based on the very specific conditions of each community or affected location. To do so, it is crucial to continue research and test various methods of construction and materials in residential homes. This study was a comparative analysis of the current roof systems implemented in residential homes, the role of hurricane testing facilities in maintaining building codes, and how damage incurred by hurricanes can be significantly reduced through a shift in the approach of homeowner insurance incentive. The purpose of this study was to provide a feasible and practicable solution for increasing implementation of hurricane resistant construction into homes. The results of this analysis concluded that there is a low percentage of homeowners investing in making their homes hurricane resilient. By re-inventing the incentive methods that insurance companies offer, this problem can step into the right direction in making more homes hurricane resilient consequently reducing damages, deaths, and economic loss.

Description
This thesis explores the task of creating industry-based marketing materials to assist academic programs in their recruitment of high school and community college students. With consistent reductions to public university budgets there is an increasing pressure on academic programs to raise their student enrollment figures, as student count is often cited as one of the most important statistics when making budget decisions. Many academic programs are ill-equipped to perform this task, however, as their personnel are not trained as recruiters, but rather as professors and industry professionals; furthermore, the university-level recruitment staff faces the impossible task of advertising every department's recruitment message. The Del E. Webb School of Construction has embarked upon a journey to create industry-based marketing materials to aid them in their recruitment efforts. Construction management (CM) has traditionally been viewed as a technology major relegated to vocational students and those not fit for baccalaureate programs. In recent years that perception has changed, however, as the industry has become increasingly complex and CM programs actively work to recruit students. In an attempt to increase that recruitment, the Del E. Webb School has created marketing materials that are signature to the program featuring the world's most widely-used building material, concrete, to create a keepsake for prospective students. This keepsake comes in the form of concrete replicas of the new ASU Pitchfork logo. These pitchforks are small and designed to be mass produced so that they can be handed out at recruitment events either on campus or in local schools. The Del E. Webb School had previously experimented with flexible rubber molds and flowable mixtures, such that the models could be easily cast and rapidly demolded and reset for casting. There were issues, however, as those pitchforks did not meet desired level of quality and were difficult to reproduce. This thesis thus describes an experimental program examining different casting and demolding regimens in an attempt to find the optimal way to create the pitchforks on a consistent basis. Following this, an operations manual for how to create the pitchforks was created in order to ensure that successive cohorts of construction students can reproduce the pitchforks in preparation for the School's annual recruitment events.

Description
The construction industry is inefficient. Technological advancements alone do not provide a full solution. By simplifying the complexity of a construction project, and implementing the views of IMT (Information Measurement Theory) through a value driven system, the construction industry can be improved. In Bechtel's recent film, Dream Big: Engineering our World, the integration of their company values on emerging engineers resulted in astounding solutions towards making the future of the construction industry more efficient as a whole. This thesis demonstrates how Bechtel was able to direct the Dream Big movement with an emphasis on leadership and simpler thinking of future generations. Under the direction of Dr. Kashiwagi's Research and Solution Model (KSM) it is possible for young people aware of their potential and understand "simplicity" to be effective leaders. Through observation, these new leaders understand that they have been making a difference since their birth. As individuals are able to identify their core values, they are better able to find their strengths, align their values with a company, and ultimately make the construction industry more efficient.

Hospitals constitute 9 percent of commercial energy consumption in the U.S. annually, though they only make up 2 percent of the U.S. commercial floor space. Consuming an average of 259,000 Btu per square foot, U.S. hospitals spend about 8.3 billion dollars on energy every year. Utilizing collaborative delivery method for hospital construction can effectively save healthcare business owners thousands of dollars while reducing construction time and resulting in a better product: a building that has fewer operational deficiencies and requires less maintenance. Healthcare systems are integrated by nature, and are rich in technical complexity to meet the needs of their various patients. In addition to being technologically and energy intensive, hospitals must meet health regulations while maintaining human comfort. The interdisciplinary nature of hospitals suggests that multiple perspectives would be valuable in optimizing the building design. Integrated project delivery provides a means to reaching the optimal design by emphasizing group collaboration and expertise of the architect, engineer, owner, builder, and hospital staff. In previous studies, IPD has proven to be particularly beneficial when it comes to highly complex projects, such as hospitals. To assess the effects of a high level of team collaboration in the delivery of a hospital, case studies were prepared on several hospitals that have been built in the past decade. The case studies each utilized some form of a collaborative delivery method, and each were successful in saving and/or redirecting time and money to other building components, achieving various certifications, recognitions, and awards, and satisfying the client. The purpose of this research is to determine key strategies in the construction of healthcare facilities that allow for quicker construction, greater monetary savings, and improved operational efficiency. This research aims to communicate the value of both "green building" and a high level of team collaboration in the hospital-building process.

Using the Arizona State University chapter of American Concrete Institute (ACI) as my platform, I recently teamed up with several generous companies to donate a new picnic slab and sidewalks to St. Vincent de Paul Elementary School's playground. Material/labor donations from Suntec Concrete, Arizona Materials, Salt River Materials Group, and Dickens Quality Demolition made it possible to complete this project over the course of two Saturdays and at no cost for the school. In addition to the children of St. Vincent de Paul's benefit, this project also gave ASU and MCC students the opportunity to work in the field with industry professionals and gain hands-on experience. Over 20 students were able to witness and participate in demolition, formwork, concrete placement (including a laser screed appearance provided by Suntec), finishing, sawcutting, and more. As for specifics, the project featured a 19' x 40' picnic slab, as well as two 6' wide sidewalks connecting the slab to the playground and the playground to the adjacent access road. Once the second sidewalk reached the access road, it continued to the classrooms with 6' wide ramps on each side for truck accessibility. My role in this project was essentially a superintendent. I served as the primary point of contact for all parties involved, organized the material and labor donations, coordinated the project schedule, and kept all companies informed of the schedule to ensure proper execution and avoid delays. Due to various unavoidable conditions (cold weather, shade on the slab, etc.), I was also forced to make a few critical decisions as the project progressed.

Description
Entering a new market in the construction industry is a complex task. Although many contractors have experienced the benefits of expanding their market offerings, many more have had unsuccessful experiences causing hardship for the entire organization. Standardized decision-making processes can help to increase the likelihood of success, but few specialty contractors have taken the time to develop a formal procedure. According to this research, only 6 percent of survey respondents and 7 percent of case study participants from the sheet metal industry have a formal decision process. Five sources of data (existing literature, industry survey, semi-structured interviews, factor prioritization workshops, and expert panel discussions) are consulted to understand the current market entry decision-making practices and needs of the sheet metal industry. The data help to accomplish three study objectives: (1) determine the current processes and best practices used for market entry decision-making in the sheet metal industry, (2) identify motivations leading to market entry by sheet metal contractors, and (3) develop a standardized decision process that improves market entry decision outcomes. Grounded in a firm understanding of industry practices, a three-phased decision-making framework is created to provide a structured approach to guide contractors to an informed decision. Four industry leaders with over 175 years of experience in construction reviewed and applied every step of the framework to ensure it is practical and easy to use for contractors.

Description
Regulatory agencies, such as the Occupational Safety and Health Administration (OSHA), and the National Institute of Occupational Safety and Health (NIOSH), recognize that decisions regarding occupational health are often economically driven, with worker health only a secondary concern (Ruttenberg, 2014). To investigate the four National Occupational Research Agenda (NORA) long-standing health concerns—welding fumes, crystalline silica, noise, and musculoskeletal disorders—a mixed methods research is conducted. Fourfold structuration, a holistic communication process with roots in indigenous/ancient knowledge, is used to organize data and facilitate making tangible relationships of health to productivity and profits that are abstract and often stated by industries, such as construction, as difficult to quantify. From both construction trade worker and occupational health and safety expert interviews data/codes are developed. For the qualitative method, the codes are organized into a constructivist grounded theory depicting the construction industry with regard to its foundation – profits. A theoretical exercise translating the qualitative codes into potential productivity losses is presented as a way for quantifying the abstract relationships of health to productivity. For the quantitative study, the data/codes are used to develop a comprehensive list of practices, barriers to, and catalysts for addressing health in construction. A significant quantitative finding is that occupational health and safety (OSH) experts are not traditionally involved at the highest levels of the OSHA Hierarchy of Controls, where the greatest opportunity to prevent exposure to health hazards is possible. Organized via a holistic framework, this research emphasizes our primary responsibility to each other as highlighted in recent NIOSH worker health agendas.

Description
The objective of the study was to examine the impact construction document deficiencies have on heavy/civil low-bid infrastructure projects. It encompasses the expertise of 202 heavy/civil construction professionals comprised of contactors and public project owners. The study was designed to determine the frequency and timing of when a contractor discovers construction document deficiencies on heavy/civil low bid projects. The information was correlated with further study data of when a contractor ultimately reports the discovered construction document deficiencies to the public project owner. This research data was compiled and analyzed to determine if contractors are withholding construction document deficiencies from public owners until after the project contract has been executed. The withholding of document deficiencies can benefit contractors by resulting in additional owner incurred costs and potential justification for project time extensions. As a result, further research was required to examine the impact construction document deficiencies have on project cost and schedule. Based on the study findings, it has led to the development of a Contractor Document Review Assessment. The Contractor Document Review Assessment is a risk mitigation device in which contractors and public project owners can identify construction document deficiencies on heavy/civil low-bid construction projects before the project contract has been executed.
