Description
Within the vast area of study in Organizational Change lays the industrial application of Change Management, which includes the understanding of both resisters and facilitators to organizational change. This dissertation presents an approach of gauging levels of change as it relates to both external and internal organization factors. The arena of such a test is given through the introduction of the same initiative change model, which attempts to improve transparency and accountability, across six different organizations where the varying results of change are measured. The change model itself consists of an interdisciplinary approach which emphasizes education of advanced organizational measurement techniques as fundamental drivers of converging change. The observations are documented in the real-time observed cased studies of six organizations as they progressed through the change process. This research also introduces a scaled metric for determining preliminary levels of change and endeavors to test both internal and external, or environmental, factors of change. A key contribution to the work is the analysis between both observed and surveyed data where a grounded theory analysis is used to help answer the question of what are factors of change in organizations. This work is considered to be foundational in real-time observational studies but has a promise for future additional contributions which would further elaborate on the phenomenon of prescribed organizational change.

Description
The success or failure of projects is not determined only by procedures, tasks, and technologies, but also by the project team and its effectiveness. In order to lead project teams towards successful outcomes, project managers must maintain high quality relationships in the workplace. When looking at employees’ relationships in the workplace, Social Exchange Theory introduces two types of exchanges: employee-organization and leader-member exchanges. While both types of exchanges focus exclusively on the employee’s longitudinal relationships, the interpersonal relationships among the team members are usually overlooked.
This research presents the results of a quantitative study of the interpersonal relationships of 327 project managers and assistant project managers in their workplace. Specifically, the study investigates if the quality of the relationship with particular stakeholders, such as one’s immediate supervisor (boss), peers, or subordinates, drives the individual’s quality of the relationship with other stakeholders.
Contrary to the expectations, in strictly hierarchical organizations (one direct supervisor), there is no significant correlation between the quality of relationships with the boss and the overall quality of the individual’s relationships. However, in the case of matrix organizations (two or three bosses), there are significant correlations between several variables such as the quality of the relationship, perceived importance and the time spent with each stakeholder, as well the inclination of the participant towards leadership actions. The driving relationship in matrix organizations is the one with “the most important peer”.

Description
The water and wastewater industry in the United States is in dire need of renovation due to dwindling infrastructure and requires substantial reinvestment. Design-bid-build (DBB) is the traditional method of project delivery most widely applied in this industry. However, alternative project delivery methods (APDM) are on the rise and touting the benefits of reduced project schedule and cost. The main purpose of this study is to conduct a qualitative and quantitative performance evaluation to assess the current impact of APDM in the water and wastewater industry. A national survey was conducted targeting completed water and wastewater treatment plant projects. Responses were obtained from 75 utilities and constructors that either completed their projects using DBB, construction manager at risk (CMAR), or design-build (DB). Data analysis revealed that CMAR and DB statistically outperformed DBB in terms of project speed and intensity. Performance metrics such as cost growth, schedule growth, unit cost, factors influencing project delivery method selection, scope changes, warranty and latent defects, and several others are also evaluated. The main contribution of this study was that it was able to show that for the same project cost, water and wastewater treatment plants could be delivered under a faster schedule and with higher quality through the utilization of APDM.

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
The built environment is responsible for a significant portion of global waste generation.
Construction and demolition (C&D) waste requires significant landfill areas and costs
billions of dollars. New business models that reduce this waste may prove to be financially
beneficial and generally more sustainable. One such model is referred to as the “Circular
Economy” (CE), which promotes the efficient use of materials to minimize waste
generation and raw material consumption. CE is achieved by maximizing the life of
materials and components and by reclaiming the typically wasted value at the end of their
life. This thesis identifies the potential opportunities for using CE in the built environment.
It first calculates the magnitude of C&D waste and its main streams, highlights the top
C&D materials based on weight and value using data from various regions, identifies the
top C&D materials’ current recycling and reuse rates, and finally estimates a potential
financial benefit of $3.7 billion from redirecting C&D waste using the CE concept in the
United States.

Description
Sustainable Materials Management and Circular Economy are both frameworks for considering the way we interact with the world's resources. Different organizations and institutions across the world have adopted one philosophy or the other. To some, there seems to be little overlap of the two, and to others, they are perceived as being interchangeable. This paper evaluates Sustainable Materials Management (SMM) and Circular Economy (CE) individually and in comparison to see how truly different these frameworks are from one another. This comparison is then extended into a theoretical walk-through of an SMM treatment of concrete pavement in contrast with a CE treatment. With concrete being a ubiquitous in the world's buildings and roads, as well as being a major constituent of Construction & Demolition waste generated, its analysis is applicable to a significant portion of the world's material flow. The ultimate test of differentiation between SMM and CE would ask: 1) If SMM principles guided action, would the outcomes be aligned with or at odds with CE principles? and conversely 2) If CE principles guided action, would the outcomes be aligned with or at odds with SMM principles? Using concrete pavement as an example, this paper seeks to determine whether or not Sustainable Materials Management and Circular Economy are simply different roads leading to the same destination.

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
As the construction industry in Saudi Arabia was on its way to thriving again. Their growth was due to the unprecedented volume of planned projects such as large-scale and unique projects. Suddenly, the world was faced with one of the most disrupting events in the last century which had a devastating impact on the construction industry specifically. This paper explores mainly the impact of the COVID-19 pandemic on construction projects in Saudi Arabia. Particularly, this paper explores how the pandemic and its related events contributed to the projects' schedule disturbances. This is because most of the projects rely on manpower and supply chains which were heavily disrupted due to the protective measures. For that, a study was conducted to evaluate the impact on the construction projects in Saudi Arabia, to what extent the schedule projects were affected, and what were the main reasons for the schedule delays. The research relied on a field survey and schedule analysis for 12 projects which resulted in identifying several causes of delays and the delayed durations that the projects in Saudi Arabia were facing. This research allows those in construction fields to identify the main causes of delays in order to avoid or minimize the impact of these issues on future projects.

Description
In a world where everything is drifting away from the intellectual into materialistic, and where everyone is rushing on the daily basis to provide their basic needs, everything is getting more expensive except the human life’s worth. Construction sites can be some of the clearer examples that show how the technical work, the communication skills, team work and management relate to one another. However, lately, the safety of the labor is neither being prioritized nor considered an important aspect to even consider at sites. Lebanon is, unfortunately, one of the countries where most construction sites are aimed to increase production and decrease cost as much as possible, on behalf of labor safety measurements. The high occurrence of such cases are the result of the lack of government control and accountability, as well as other reasonings.
Similar to the majority of countries, falls are the number one cause of fatalities and serious injuries on construction sites, especially building sites, where working on higher elevations is a must.
This thesis focuses on the topic of “Techniques and technologies for reducing fall hazards in use on Lebanese building construction projects”. The main goal behind it is to shed light on whether there are any traditional, technical or modern mechanisms used for safety on the Lebanese construction sites, however statistically few they might be. On the other hand, Casting the deficiencies, weaknesses and flaws are also discussed by indicating some solutions and pointers on possible methods to improve. Hence, this thesis would demonstrate the high importance of this topic and consequently help construction managers and workers realize that safety should become a priority on all sites in the country.
Researches done and interviews conducted show that fall hazards prevention/protection techniques are only implemented by large scale companies, and totally ignored by other companies which constitute the highest percentage of the active companies in the market now. Several causes are behind this and the result is one: More lives are put in danger due to lack of education, absence of audits and sanctions, and insufficient budgets

Description
Much of the water and wastewater lines in the United States are nearing the end of their useful life. A significant reinvestment is needed in the upcoming decades to replace or rehabilitate the water and wastewater infrastructure. Currently, the traditional method for delivering water and wastewater pipeline engineering and construction projects is design-bid-build (DBB). The traditional DBB delivery system is a sequential low-integration process and can lead to inefficiencies and adverse relationships between stakeholders. Alternative project delivery methods (APDM) such as Construction Manager at Risk (CMAR) have been introduced to increase stakeholder integration and ultimately enhance project performance. CMAR project performance impacts have been studied in the horizontal and vertical construction industries. However, the performance of CMAR projects in the pipeline engineering and construction industry has not been quantitatively studied.
The dissertation fills this gap in knowledge by performing the first quantitative analysis of CMAR performance on pipeline engineering and construction projects. This study’s two research objectives are:
(1) Develop a CMAR baseline of commonly measured project performance metrics
(2) Statistically compare the cost and schedule performance of CMAR to that of the traditional DBB delivery method
A thorough literature review led to the development of a data collection survey used in conjunction with structured interviews to gather qualitative and quantitative performance data from 66 completed water and wastewater pipeline projects. Performance data analysis was conducted to provide performance benchmarks for CMAR projects and to compare the performance of CMAR and DBB.
This study provides the first CMAR performance benchmark for pipeline engineering and construction projects. The results span across seven metrics in four performance areas (cost, schedule, project change, and communication). Pipeline projects delivered using CMAR have a median cost and schedule growth of -5% and 5.10%, respectively. These results are significantly improved from DBB baseline performance shown in other industries. To verify this, a statistical analysis was done to compare the cost and schedule performance of CMAR to similar DBB pipeline projects. The results show that CMAR pipeline projects are being delivered with 6.5% less cost growth and with 12.5% less schedule growth than similar DBB projects, providing owners with increased certainty when delivering their pipeline projects.
