Description
Utilizing the Arizona State University's Performance Based Studies Research Group, and their PIPS program, a roofing materials manufacturing company can evaluate performance of representatives, products and contractors. Service life of the systems can be tracked and customer satisfaction measured it provides an objective viable tool for the consumer to choose a quality product and contractor without the distractions of marketing, promises, or a salesman's hype. Facilities purchasing a new roof system, can benefit from the information gathered as a guide in making sound, value based decisions. Creating a historical, concise and accurate documentation of roofing systems is a benefit to all involved. The procurement process, installation and longevity of the roofing systems can be tracked and graded.

Description
As a term and method that is rapidly gaining popularity, Building Information Modeling (BIM) is under the scrutiny of many building professionals questioning its potential benefits on their projects. A relevant and accepted calculation methodology and baseline to properly evaluate BIM's benefits have not been established, thus there are mixed perspectives and opinions of the benefits of BIM, creating a general misunderstanding of the expected outcomes. The purpose of this thesis was to develop a more complete methodology to analyze the benefits of BIM, apply recent projects to this methodology to quantify outcomes, resulting in a more a holistic framework of BIM and its impacts on project efficiency. From the literature, a framework calculation model to determine the value of BIM is developed and presented. The developed model is applied via case studies within a large industrial setting where similar projects are evaluated, some implementing BIM and some with traditional non-BIM approaches. Cost or investment metrics were considered along with benefit or return metrics. The return metrics were: requests for information, change orders, and duration improvements. The investment metrics were: design and construction costs. The methodology was tested against three separate cases and results on the returns and investments are presented. The findings indicate that in the tool installation department of semiconductor manufacturing, there is a high potential for BIM benefits to be realized. The evidence also suggests that actual returns and investments will vary with each project.

Description
Commodity contracts are often awarded on the basis of price. A price-based methodology for making such awards fails to consider the suppliers' ability to minimize the risk of non-performance in terms of cost, schedule, or customer satisfaction. Literature suggests that nearly all risk in the delivery of commodities is in the interfacing of nodes within a supply chain. Therefore, commodity suppliers should be selected on the basis of their past performance, ability to identify and minimize risk, and capacity to preplan the delivery of services. Organizations that select commodity suppliers primarily on the basis of price may experience customer dissatisfaction, delayed services, low product quality, or some combination thereof. One area that is often considered a "commodity" is the delivery of furniture services. Arizona State University, on behalf of the Arizona Tri-University Furniture Consortium, approached the researcher and identified concerns with their current furnishing services contract. These concerns included misaligned customer expectations, minimal furniture supplier upfront involvement on large capital construction projects, and manufacturer design expertise was not being utilized during project preplanning. The Universities implemented a best value selection process and risk management structure. The system has resulted in a 9.3 / 10 customer satisfaction rating (24 percent increase over the previous system), for over 1,100 furniture projects totaling $19.3M.

Description
Over the last twenty years, governments at all levels have made changes to increase their level of accountability and transparency. The researcher proposed that the concepts of organizational agility (OA) (leveraging core competencies, proactively seeking new opportunities, implementation of performance metrics, and strategically planning projects) are well-aligned with the public accountability systems. In the first part of this dissertation, the researcher examined the components of a “Value-Based Model” for public works contractor selection and project delivery, and its propensity to increase public accountability. The researcher studied 415 projects ($561.47M value) delivered with the Value-Based Model at eight different public agencies over a ten-year period.
Next, the researcher analyzed factors affecting contractor organizational agility. In light of the “Great Recession”, the concepts of organizational agility offers insights into companies could have made different strategic decisions to avoid many of the issues faced. Construction was particularly affected: by January 2010, unemployment reached approximately 20 percent. One way to combat declining profits is to adjust general overhead costs (indirect expenses). These costs include items such as home office expenses, business development, and bonuses. The objective of the second part of this research was to conduct a study of how contractors responded to dynamic market conditions and to identify if whether contractors’ company attributes impacted their responses to the market changes. A total of 437 contractors responded to the survey, and 92 percent reported that they reduced overhead costs in five areas, by an average of about 15 percent. Additional analysis suggests that there are distinct categories of overhead flexibility.
