Project Delivery Method

Even though the design-build (DB) delivery method has become a popular construction project delivery method in many countries, it is relatively rare in Taiwan. This study investigates the problems and difficulties that Taiwanese owners may encounter during using DB delivery methods. Twenty six problems over the four key stages of the DB process were first identified based on previous studies and expert interviews. A questionnaire survey was then conducted to determine the most pressing problems for Taiwan. The results of statistical analyses show that Taiwanese owners face key problems at all stages of the DB delivery method, especially during the tender preparation and valuation stages. These findings can be used by Taiwanese owners for successfully executing DB projects.

The choice of a suitable delivery method plays a considerable role in the performance of a construction project. Previous research has attempted the development of a systematic approach to project delivery method selection focusing on performance information. However, such attempts did not properly address public agencies and legislative impediments are almost entirely neglected as suggested variables in such models. This paper addresses these limitations by presenting a quantitative analysis to test whether federal and state legal limitations do influence project performance. Project characteristics from the U.S. General Services Administration Capital Construction Project database are presented. The database is analyzed using cross-tabulation to determine potential correlations among the variables, and specifically their relation to project delivery method choice and performance information. Contributions from this research are reflected in presenting a methodology for choosing alternative delivery methods while considering project characteristics and specifically the legislative impediments associated with a construction project and their influence on project performance.

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.

Project Delivery Method

This paper focuses on providing a methodology to optimize the selection of multiple project delivery methods for multi-project transportation systems under uncertainty. In contrast to previous studies, this paper considers that owners sometimes divide transportation projects into sub-projects that are constrained by construction sequence. The owners’ objectives are to minimize the total project cost and duration for the whole multi-project undertaking by selecting the most appropriate project delivery method for each sub-project. The complexity of this problem is the motivation for the development of a multi-objective decision making model that can help owners evaluate and choose the appropriate project delivery method for each sub-project. The model considers three fundamental project delivery methods, i.e., design–bid–build, design–build, and construction manager-as-general contractor. The project cost and duration of each sub-project when selecting different project delivery methods are estimated by experts employed and/or retained by the owner, and regarded as fuzzy variables. Furthermore, a fuzzy simulation-based multiple objective particle swarm optimization algorithm is developed to find feasible Pareto solutions. Results and analysis of a numerical example are presented to highlight the performance of the model.

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

The decisions on the project delivery method when conducting a construction project are an important part of the process and can heavily influence the success or failure of the project. Many factors have to be considered, however, in determining the project delivery method, and there are no definite criteria. This ambiguity can cause much difficulty. As such, this paper proposes a system based on case-based reasoning (CBR) that supports the decision-making for project delivery method selection considering the future construction project performance. The research was conducted with focus on the road construction case dataset. Based on this, the proposed decision-making support system was devised by applying decision tree (DT) analysis, the effectiveness of selecting a project delivery method for the project performance index (ESDPI), and CBR. This system can consider not only the project delivery method but also the later construction project performance, and can thus effectively support the owner’s decision-making.
