Cost Comparison of Public Elementary School Construction Costs Based on Project Delivery System in the State of Texas

Reinisch, Ashley 2011 December 1900 (has links)
If a correlation exists between cost and project delivery system then this is crucial knowledge for any group organizing a new construction project. It has been observed anecdotally that the construction cost per student of public elementary schools has been observed to continue to increase in the state of Texas, even with the recent downturn in the economy. The recent economic depression in the USA has seen construction material costs stagnate and construction costs dropping. This is a direct result of the competitive nature of a market that has a lack of business. The issue of a rising cost at the time of a falling market is of more than a passing research interest to school superintendents and the people of Texas. This study investigated the relationship between cost and project delivery systems. A survey was sent to all school superintendents in Texas requesting recent data on elementary school enrollment, project delivery type and construction costs. One hundred and thirty six responses were received from one thousand and seventy six Texas school districts. A comparative means test was used to determine if a relationship exists between construction cost per student and project delivery system for public elementary schools in Texas. The research shows that Texas school districts are primarily using two types of project delivery systems for their new school construction, Construction Management at Risk and Competitive Sealed Proposals. After comparing the average construction cost per student for these two project delivery systems, the statistical analysis showed that Competitive Sealed Proposals cost approximately four thousand dollar less per student than Construction Management at Risk. The clear question is then as to why are districts using Construction Management at Risk when the comparative benefits of the contract type are not worth this amount of money per student.

Analysis of the State of Practice and Best Practices for Alternative Project Delivery Methods in the Transportation Design and Construction Industry

January 2014 (has links)
abstract: Alternative Project Delivery Methods (APDMs), namely Design Build (DB) and Construction Manager at Risk (CMAR), grew out of the need to find a more efficient project delivery approach than the traditional Design Bid Build (DBB) form of delivery. After decades of extensive APDM use, there have been many studies focused on the use of APDMs and project outcomes. Few of these studies have reached a level of statistical significance to make conclusive observations about APDMs. This research effort completes a comprehensive study for use in the horizontal transportation construction market, providing a better basis for decisions on project delivery method selection, improving understanding of best practices for APDM use, and reporting outcomes from the largest collection of APDM project data to date. The study is the result of an online survey of project owners and design teams from 17 states representing 83 projects nationally. Project data collected represents almost six billion US dollars. The study performs an analysis of the transportation APDM market and answers questions dealing with national APDM usage, motivators for APDM selection, the relation of APDM to pre-construction services, and the use of industry best practices. Top motivators for delivery method selection: the project schedule or the urgency of the project, the ability to predict and control cost, and finding the best method to allocate risk, as well as other factors were identified and analyzed. Analysis of project data was used to compare to commonly held assumptions about the project delivery methods, confirming some assumptions and refuting others. Project data showed that APDM projects had the lowest overall cost growth. DB projects had higher schedule growth. CMAR projects had low design schedule growth but high construction schedule growth. DBB showed very little schedule growth and the highest cost growth of the delivery methods studied. Best practices in project delivery were studied: team alignment, front end planning, and risk assessment were identified as practices most critical to project success. The study contributes and improves on existing research on APDM project selection and outcomes and fills many of the gaps in research identified by previous research efforts and industry leaders. / Dissertation/Thesis / Doctoral Dissertation Civil Engineering 2014

Organizational Change Management for the Adoption of Alternative Project Delivery Methods within the AEC Industry

January 2020 (has links)
abstract: The alternative project delivery methods (APDMs) today are being increasingly used by owner organizations in the architecture, engineering, and construction (AEC) industry. Yet the adoption of these methods can be extremely difficult to accomplish and requires significant change management efforts. To facilitate the APDM adoption, this research aimed to better understand how AEC owner organizations have changed from only using the design-bid-build method to also successfully implementing APDMs from an organizational change perspective. This research utilized a literature review, survey and interviews to fulfill the research objectives. The dissertation follows a three paper format. The first paper focuses on identifying organizational change management (OCM) practices that, when effectively executed, lead to increased success rates of adopting APDMs in owner AEC organizations. The results of the first paper indicated that the five OCM practices with the strongest correlations to successful APDM adoption were realistic timeframe, effective change agents, workload adjustments, senior-leadership commitment, and sufficient change-related training. The second paper focuses on investigating AEC employees’ reactions to the adoption of APDMs. The findings of the second paper revealed that employees in AEC organizations react favorably to adopting a change in their project delivery systems. The findings further revealed that increasing the use of OCM practices is related to decreased employee resistance to change. The third paper aimed to provide guidelines detailing on how to lead APDM adoption. The findings of the third paper indicated that there was a general sequence of four implementation phases, which were preparing and planning, pilot project testing, expanding to the intended scale, and sustaining and evaluating. The phases include specific OCM practices that increase the probability of successful APDM adoption. The dissertation results can help in guiding the senior managers of construction organizations and OCM consultants to effectively implement APDMs for the first time in the construction sector. / Dissertation/Thesis / Doctoral Dissertation Construction Management 2020

Can a technological tool resolve issues in project management? : A case study for an IT projects consulting firm.

Snäll, Josephine January 2021 (has links)
IT projects are complex and often numerous challenges arise during the projects’ execution. The ten knowledge areas designed to support projects management more often challenge include the project management team to deliver the outcome on time. The present study tries to answer the question of whether the use of a technological management tool in project management can help to solve most problematic knowledge areas, and to meet the delivery deadlines. The author runs a case study at an IT consulting firm. The purpose for the study is to investigate if technologies can help to resolve these issues, and to recommend a project management tool for more efficient delivery time. In a two phased study, first, the author identifies the project management knowledge areas that may have impacted IT project delivery delays, and second, the author investigates if using a project management tool can solve the delivery time issue. Results from the first phase show that delivery issues emerged at different levels, namely: stakeholders, resources, scope, quality, and integration management.  To investigate if a management tool could help to overcome the delays in delivery, a selection of technological tools was made. Based on the results from the first phase so the technological tool integrates functions and features for stakeholders, resources, scope quality, and integration management. The interviewees then ranked three technological tools and shared opinions on possible adoption of any of these tools. Final analysis show that interviewees think that proposed technological tools can resolve some of the issues experienced in the projects: mainly, the transition between departments, resource allocation, to visualise the quality management, plan for communication with stakeholders, and clearer handling of the project’s requirements. In the final results from the second interview, the tool that can help to solve issues with the five most problematic knowledge areas, and thus the delivery delays issue, for the case company is Genius Project.

An Investigation of Project Delivery Methods Relating to Repetitive Commercial Construction

Patterson, Donald A. 10 July 2014 (has links) (PDF)
The Design/Bid/Build (DBB) delivery method has historically been the most popular and the most effective means of determining the least cost for building a project based upon a set of construction documents. In recent years, however, other project delivery methods, including but limited to Construction Manager/General Contractor (CM/GC) and Design/Build (DB), have slowly taken a share of the construction market away from the DBB delivery method. The choice of delivery method that will produce the best value for an owner in the measurements of efficiency in quality, cost, and timeliness depends upon the type of project and the business culture of the project owner. A unique opportunity for a comparative study was presented by the Meetinghouse Facilities Department (MFD) of the Church of Jesus Christ of Latter-day Saints. The MFD completed over 200 repetitive meetinghouse projects in the U.S. over a five-year period (1999-2003), contracting approximately two-thirds of the projects using a CM/GC delivery method with an attached partnering agreement. The remaining meetinghouses were contracted using a DBB delivery method. A comprehensive comparison was conducted measuring all of the efficiencies created by the selection of delivery method, including short- and long-term costs, direct and indirect costs, construction cycle time, and quality assessment scores. After identifying and then adjusting for several confounding variables in the historical data, the statistical analysis provided evidence that the CM/GC delivery method proved to be the best value for the MFD by producing a total cost savings of over 5.5 percent on the meetinghouse projects when compared to the DBB meetinghouse projects. Construction cycle time was 20% shorter on the CM/GC meetinghouse projects and quality assessment (QA) scores were consistently higher. In regards to a 10-year life cycle repair costs, the CM/GC delivery method produced a higher quality meetinghouse, reducing repair costs by 34% when compared to the DBB meetinghouse projects.

Case-based Study and Analysis of Integrated Project Delivery (IPD) Approach and Trust-Building Attributes

Pishdad-Bozorgi, Pardis 06 August 2012 (has links)
The goal of this Ph.D. research is to explore the IPD contractual strategies, to highlight the elements that distinguish IPD from a traditional delivery approach, to analyze how trust-based relationships are established and promoted, and to demonstrate if/how trust and IPD contractual principles correlate. The result of this research will promote the understanding of the industry on the strategies that promote trust and integration through real world case studies. The significance of the subject becomes more evident when reflecting on the current industry's crisis: productivity loss, fragmented delivery process, and lack of trust and collaboration. Through a literature review a Project Delivery and Contracting Strategies (PDCS) framework, an IPD traits framework, and a trust-Building framework are developed. The frameworks are used as the organizational tools to structure and inquire relevant information on the two IPD projects. An expert panel is assembled to discuss the frameworks and the findings of literature analysis and to seek the industry's insight on the units of analysis for contract, and the units of measure for trust. The units of analysis for contract are elements, such as strategies for risks/rewards sharing, liability considerations, decision making authority, and governance. The units of measure for trust are the individuals' perception, and the trust-building attributes as outlined in table 4-1. Two IPD projects were selected and their contract agreements were studied. A questionnaire including both open-ended questions and multiple choice questions was developed based on the information collected through: 1. the IPD agreements in each case study, 2. the literature-based frameworks on trust and project delivery contracting strategies. Accordingly, two IPD case studies are developed following the analysis of their IPD agreements and the individual one-on-one interviews with their key IPD players. The trust-building framework presented in this work includes a series of techniques that the contracting parties can follow when establishing their contractual and managerial strategies and also when interacting with each other. / Ph.

Contract Administration Functions and Tools for Design-Build and Construction Manager/General Contractor Project Delivery in U.S. Highway Construction

January 2019 (has links)
abstract: The demand for new highway infrastructure, the need to repair aging infrastructure, and the drive to optimize public expenditures on infrastructure have led transportation agencies toward alternative contracting methods (ACMs) such as design-build (DB) and construction manager/general contractor (CM/GC). U.S. transportation agencies have substantial experience with traditional design-bid-build delivery. To promote ACMs, the Federal Highway Administration and the National Cooperative Highway Research Program (NCRHP) have published ACM guidance documents. However, the published material and research tend to focus on pre-award activities. The need for guidance on ACM post-award activities is confirmed in NCHRP’s request for a guidebook focusing on ACM contract administration (NCHRP 2016). This dissertation fills the crucial knowledge gap in contract administration functions and tools for DB and CM/GC highway project delivery. First, this research identifies and models contract administration functions in DBB, CM/GC, and DB using integrated definition modeling (IDEF0). Second, this research identifies and analyzes DB and CM/GC tools for contract administration by conducting 30 ACM project case studies involving over 90 ACM practitioners. Recommendations on appropriate use regarding project phase, complexity, and size were gathered from 16 ACM practitioners. Third, the alternative technical concepts tool was studied. Data from 30 DB projects was analyzed to explore the timing of DB procurement and DB initial award performance in relation to the project influence curve. Types of innovations derived from ATCs are discussed. Considerable industry input at multiple stages grounds this research in professional practice. Results indicate that the involvement of the contractor during the design phase for both DB and CM/GC delivery creates unique contract administration functions that need unique tools. Thirty-six DB and CM/GC tools for contract administration are identified with recommendations for effective implementation. While strong initial award performance is achievable in DB projects, initial award performance in this sample of projects is only loosely tied to the level of percent base design at procurement. Cost savings typically come from multiple ATCs, and innovations tend to be incremental rather than systemic, disruptive, or radical. Opportunity for innovation on DB highway projects is influenced by project characteristics and engaging the DB entity after pre-project planning. / Dissertation/Thesis / Doctoral Dissertation Civil, Environmental and Sustainable Engineering 2019

Supervisión y control de obras de edificación bajo los enfoques de Lean Construction y del PMI / Supervision and control of works in building construction under the Lean Construction and PMI approaches

Cary Teves, Walter Melvin 17 November 2018 (has links)
El propósito de esta investigación consistió en la realización de una propuesta para la implementación de un sistema de gestión para la apropiada supervisión y control de obras de edificación con base en el trabajo colaborativo. El caso de estudio se basó en la construcción de un hotel en el departamento de Cusco. Para ello fue necesario establecer lineamientos para el desarrollo de la propuesta, luego se describió la metodología de gestión y control utilizado por la supervisión de obra. Se realizó la definición de herramientas de gestión y técnicas de control más convenientes para este propósito. Esta investigación se fundamenta en que la mayor parte de proyectos de edificación son ejecutados descuidando el tiempo, costo, alcance y calidad establecidos; debido a procedimientos inadecuados de supervisión y control. Por otro lado, las controversias y relaciones adversas que se producen entre la supervisión de obra, constructor y cliente, son aspectos que pueden causar impactos significativos en las variables mencionadas. Esta propuesta permite que la supervisión de obra pueda efectuar la entrega integrada del proyecto mediante el trabajo colaborativo, utilizando la metodología del Valor Ganado para una adecuada gestión, y aplicando la técnica del Last Planner para el apropiado control y monitoreo del cronograma y de las actividades en ejecución. Finalmente, se concluye que la aplicación de las herramientas y metodologías expuestas, posibilitan a la supervisión de obra gestionar y controlar apropiadamente el alcance, el cronograma, los costos y la correcta ejecución de todos los trabajos que se realizan en obra. / The purpose of this investigation was to make a proposal for the implementation of a management system for the proper supervision and control of works in building construction based on collaborative work. The case study focuses on the construction of a hotel located in the Cusco department. This required the establishment of guidelines for the development of the proposal, and then it was described the management and control methodology used by the site supervisors. The most convenient management tools and control techniques for this purpose were defined. This research is based on the fact that the majority of building projects are executed neglecting the established time, cost, scope and quality due to inadequate supervision and control procedures. On the other hand, controversies and adverse relationships that occur between supervisors, constructor and owner are aspects that can cause significant impacts on the variables mentioned above. This proposal allows the site supervisors to carry out the integrated project delivery through collaborative work, using the Earned Value Methodology for proper management, and applying the Last Planner technique for proper control and monitoring of the progress of the production activities and protect the stipulated deadline in the project's general schedule. Finally, it is concluded that the application of the exposed tools and methodologies enable the site supervisors properly manage and control the scope, schedule, costs and the correct execution of all the works that are carried out on site. / Trabajo de investigación

Impact to alternative contracting methods using multivariate analysis in the regulatory environment

Smith, Valerie Rose Riecke 24 June 2008 (has links)
This research addresses legislative impediments inherent to working in the government construction industry by investigating whether benefits exist when using alternative project delivery methods, and whether legislative limitations allowing the use of alternative project delivery methods impede any such benefits from being realized. The research begins by defining the project delivery method process, and explains in detail the four primary types and how they function. The research then provides a qualitative study that presents the perceived advantages and disadvantages of each method. Then, a second literature review provides an overview of previously published research in project delivery method selection, and examines federal and state legislative trends to establish the growing debate associated with alternative project delivery methods, focusing on the design-build method of project delivery. Finally, a quantitative analysis is presented to test whether federal and state legislative limitations influence the realization of any benefits of alternative project delivery methods, and specifically design-build, for federal projects. Project characteristics from the U.S. General Services Administration Capital Construction Project database are tested. The research suggests that when an alternative project delivery method, specifically design-build, is chosen, there are benefits in time and cost savings, and the ability to use the alternative project delivery method is affected by the removal of federal and state legislative impediments.

Alternative to low bid selection in Air Force reserve military construction: approach to best value procurement

Garner, Birtice A. 01 July 2009 (has links)
Best value is becoming one of the most commonly used procurement methods in the facility construction industry. The Federal Government and the Air Force Reserve predominant project delivery approach has been via the low-bid award. This process has not been successful, documented by large numbers of construction modifications, as well as project cost and schedule growth over the past sixteen years. Recently, federal procurement agencies have attempted to move toward construction awards based upon best value principles relative to performance and price. The United States Army Corps of Engineers best value procurement vehicle known as Military Transformation fails to deliver true best value. This pseudo best value delivery process: (1) fails to objectively rate and apply contractor past performance; (2) lacks the means to monetarily quantify contractor proposal risks; and (3) provides no means of transferring control and responsibility for risks and risk minimization to the contractor. Only a true best value project delivery system can provide the urgently required increased efficiency necessary for Air Force Reserve Command to remain a dependable military institution capable of erecting facilities contributory to our nation's defense by perpetually adding value to the project delivery process.
