Project delivery planning is a key stage used by the project owner (or project investor) for organizing design, construction, and other operations in a construction project. The main task in this stage is to select an appropriate project delivery method. In order to analyze different factors affecting the PDM selection, this paper establishes a multiagent model mainly to show how project complexity, governance strength, and market environment affect the project owner’s decision on PDM. Experiment results show that project owner usually choose Design-Build method when the project is very complex within a certain range. Besides, this paper points out that Design-Build method will be the prior choice when the potential contractors develop quickly. This paper provides the owners with methods and suggestions in terms of showing how the factors affect PDM selection, and it may improve the project performance.

Design-Build (DB) and Build-Operate-Transfer (BOT) contracts are the two types of public-private-partnerships that are widely used in the region that are aimed in this study. The objectives of this study were to analyze and compare DB and BOT projects in terms of project costs and durations. In order to analyze and compare Design-Build (DB) and Build-Operate-Transfer (BOT) projects, this study collected data by means of convenient random sampling, from construction projects built by five ministries of Republic of Turkey. Statistical tests were conducted to determine if the metrics related to cost and schedule were significantly different from each other in these two types of projects. The findings of this study will help the public agencies decide what delivery method is best for their projects in terms of controlling costs and schedule. Results show that DB projects outperform BOT projects in terms of cost and schedule. The results of this research will enable governments to become more familiar with comparisons between DB and BOT distribution methods, and the findings will help the ministries to choose swhich delivery method is suitable for use on a project-based.

Co-location is a process that involves bringing the constituents of a project together in a shared space with the intent of enhancing team effectiveness. When used with the design-build delivery method, formal communication barriers are circumvented. However, do all the project constituents perceive the same value from co-location? This research examines the benefits of co-location when used for a design-build project and includes the perceptions of 101 Design Build Institute of America (DBIA) design practitioners. Within the responses, communication, collaboration, and team chemistry were the most highly ranked benefits with this group. However, the open-ended feedback indicated that project size and complexity, disruptions to intra-organizational collaboration, organizational structure incompatibility for co-location, the absence of the owner and the use of technology were found to be barriers against the use of co-location. Analyzing these perceptions and the barriers shed awareness into a process that may be perceived differently among its constituents – allowing for focus on ways in which to improve co-location.

Design–build (DB) is adopted as a project delivery method in hopes to improve performance. Previous studies focus on upstream issues such as conditions for adoption and contractor selection, but few address the design and construction coordination issues that are very likely to be encountered in execution by new users. This paper investigates coordination problems arising from design and construction concurrence and solutions by studying five ongoing DB projects and interviewing nine major contract parties. Inconsistent application of the design and construction process and infrequent feedback are two major problems found to have high influence on DB execution. A work unit planning process with five steps is presented in this paper to help better manage the design and construction coordination of a DB project.

This paper discusses the design-build project delivery method which is becoming an increasingly viable alternative to traditional project delivery method in the public sector. This interest has led to dialogue among public sector agencies to establish and formalise understanding of the design-build process and its implementation. The process consists of six stages namely Project Definition, Request for Qualification, Request for Proposal, Proposal Submission and Evaluation, Contract Award, and Document/Construction. Therefore, this finding of Design-Build (DB) procurement process is on the improvement and understanding on an owner and contractor in practice and implementation in Malaysia.  Keywords: design/build, design/bid/build, advantage and disadvantage, procurement process

Performance in the construction industry is wrought with challenges and owners often are victim to cost and schedule overruns, particularly on high profile projects that are large, complex, and risky. Alternative project delivery methods and techniques are continually being developed and implemented by buyers of construction services to address these problems. The Best Value Business Model (BVBM) has been rigorously tested and shown to improve project performance via its three-phased approach to project delivery. BVBM increases performance throughout the construction project lifecycle by utilizing value-based selection processes, pre-contract planning methodologies, and performance measurement systems. The objective of this research is to provide a detailed case study of BVBM application on a design-build project to deliver a highly complex research facility with tight schedule and budget thresholds. The implementation process is discussed in detail and project results are provided and analyzed to demonstrate the ability of BVBM to improve project performance. Special attention is paid to the ability of BVBM to optimize project cost and schedule performance through the application of a value-based selection methodology, a pre-contract preplanning period, and a weekly risk management system.
