Comparing procurement methods for design build projects
The design build delivery method is increasingly used in the United States due to numerous advantages it can offer a project. An important issue associated with design build delivery is the procurement method used to select the design build team. It is a critical decision that involves several key project team members, including the owner, designer, and contractor organizations, and requires the owner to carefully choose the design build procurement method that will be used to select the team that will deliver the project. This research quantitatively analyzed the correlation between the design build procurement method and the performance of the design build project with regard to cost, time, and quality metrics. The procurement methods studied were sole source, qualifications based, best value, and low bid selection. Data were collected through surveys from 76 design build projects in the United States. Based on the patterns and relationships identified from these data, a better understanding of the procurement process and how it influences project performance is achieved. The impact of project specific factors and guidelines are presented to assist owners in selecting the design build team procurement method that responds to their project goals.

Empirical Comparison of Design/Build and Design/Bid/Build Project Delivery Methods
This study compares the performance of design/bid/build and design/build to see if one project delivery method is superior in regards to time and cost. Similar military buildings were used to identify two samples of projects delivered with each of the two delivery methods. These projects provide a meaningful comparison because they include buildings of the same typology (i.e. U.S. Navy Bachelor Enlisted Quarters) delivered using similar design models. Project duration, project duration per bed, project time growth, cost growth and cost per bed were statistically compared. Upon completion of the analysis, the hypothesis that design/build projects are superior to design/bid/build projects in regards to time and cost was tested. Design/build projects were proven superior in performance in almost every measure. Other findings, including recommendations to practitioners and researchers, will be provided as well.

Supply chain design and analysis: Models and methods
Abstract For years, researchers and practitioners have primarily investigated the various processes within manufacturing supply chains individually. Recently, however, there has been increasing attention placed on the performance, design, and analysis of the supply chain as a whole. This attention is largely a result of the rising costs of manufacturing, the shrinking resources of manufacturing bases, shortened product life cycles, the leveling of the playing field within manufacturing, and the globalization of market economies. The objectives of this paper are to: (1) provide a focused review of literature in multi stage supply chain modeling and (2) define a research agenda for future research in this area.

Predicting Performance of Design Build and Design Bid Build Projects
Design build (DB) and design bid build (DBB) are two principal project delivery systems used in many countries. This paper reports on models constructed to predict performance of DB and DBB projects on 11 areas, using project specific data collected from 87 building projects. The study included collecting, checking, and validating industry data, and the statistical development of multivariate linear regression models for predicting project performance. Robust models are developed to predict construction and delivery speeds of DB and DBB projects. Gross floor area of the project is the most significant factor affecting speed. Besides this, for DBB projects, contractors' design ability, and adequacy of plant and equipment would ensure speedy completion of the projects. For DB projects, if the contract period is allowed to vary during tender evaluation, this would slow down the project. Robust models to predict turnover and system quality of DB projects are also constructed. A DB contractor's track record is.

Design and Build Procurement System Contractor Selection
Abstract One of the contract awarding systems in public sector in Poland is the Design Build system. In this system, a client concludes a contract agreement with only one company, a contractor, in order to carry out both design and construction of works. While deciding on this form of delivery of a public project, the client is obliged to conduct a single proceeding aiming to select the contractor. In this paper, public works contracts awarded in the D&B system in Poland are analysed, whilst attention was put on the contracting modes and assessment criteria. The results are assessed against the experience of other countries and recommended methods for selection of the Design and Build contractor.

A Theory of Incentives in Procurement and Regulation
More then just a textbook, A Theory of Incentives in Procurement and Regulation will guide economists' research on regulation for years to come. It makes a difficult and large literature of the new regulatory economics accessible to the average graduate student, while offering insights into the theoretical ideas and stratagems not available elsewhere. Based on their pathbreaking work in the application of principal agent theory to questions of regulation, Laffont and Tirole develop a synthetic approach, with a particular, though not exclusive, focus on the regulation of natural monopolies such as military contractors, utility companies, and transportation authorities. The book's clear and logical organization begins with an introduction that summarizes regulatory practices, recounts the history of thought that led to the emergence of the new regulatory economics, sets up the basic structure of the model, and previews the economic questions tackled in the next seventeen chapters. The structure of the model developed in the introductory chapter remains the same throughout subsequent chapters, ensuring both stability and consistency. The concluding chapter discusses important areas for future work in regulatory economics. Each chapter opens with a discussion of the economic issues, an informal description of the applicable model, and an overview of the results and intuition. It then develops the formal analysis, including sufficient explanations for those with little training in information economics or game theory. Bibliographic notes provide a historical perspective of developments in the area and a description of complementary research. Detailed proofs are given of all major conclusions, making the book valuable as a source of modern research techniques. There is a large set of review problems at the end of the book.

PUBLIC PROCUREMENT RE EXAMINED
Academically, public procurement has been a neglected area of study even though governmental entities and public procurement practitioners have diligently worked to improve public procurement practices. This article will identify common elements of public procurement knowledge through a brief analysis of the literature and will provide a summary of government efforts to improve public procurement practices. In addition, this article will comprehensively re examine public procurement by using a systems approach as a method of inquiry. Finally, implications of the proposed public procurement system regarding future research and study will be discussed.

Design and Build Project Success Factors: Multivariate Analysis
This study aimed to identify a set of project success factors for design and build (D&B) projects and examine the relative importance of these factors on project outcome. Six project success factors (project team commitment, contractor's competencies, risk and liability assessment, client's competencies, end users' needs, and constraints imposed by end users) were extracted from factor analysis of data provided by 53 participants of public sector D&B projects through a questionnaire survey. Project team commitment, client's competencies, and contractor's competencies were found to be important to bring successful project outcome from the multiple regression findings. Contractor's competencies also contributed to project time performance. Project team members should also recognize that time and cost performance as well as quality of design and workmanship represent the key elements of overall success of D&B projects. Practitioners are advised to focus on teamwork and partnering for successful project compl.

Public procurement and innovation?Resurrecting the demand side
Abstract Demand is a major potential source of innovation, yet the critical role of demand as a key driver of innovation has still to be recognised in government policy. This article discusses public procurement as one of the key elements of a demand oriented innovation policy. The paper starts by signaling the new significance of public procurement for innovation policy strategies at the EU level and in a range of European countries. It then defines the concept of public procurement and embeds this concept within a taxonomy of innovation policies. The rationales and justifications of public procurement policies to spur innovation are discussed, followed by a consideration of the challenges and potential pitfalls as well as appropriate institutional arrangements and strategies, including some recent empirical examples of good practice. It concludes by confronting the public procurement approach with two of the most common objections to it and by considering future prospects.
