Design And Construction

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.

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.

Value Realization

Building information modelling (BIM) tools and workflows, new procurements methods, and emerging management practices are being adopted on projects to overcome collaboration barriers and improve project performance within the architecture, engineering, construction, and operation (AECO) sector. Academic literature and industry reports recommend the use of collaborative procurement methods such as design and build (DB) procurement and integrated project delivery (IPD) when adopting BIM workflows. However, to date there are little operationalization and empirical evidence of the value realization potential when using BIM in conjunction to these procurement methods. This chapter draws upon five case studies of BIM-based DB projects to analyze and quantify the potential of value realization using clash detection as a use value. The results reveal potential hurdles inhibiting BIM from reaching its full potential. Accordingly, recommended changes to the current processes are suggested to facilitate BIM in enhancing value on DB projects.

Ranking Analysis

Prefabrication has been widely adopted in the construction projects in recent years. It has also been advocated as a greener and more sustainable approach of project delivery. However, with a wealth of evidence supporting other reasons as the drivers of using prefabrication, it is questionable whether the real goal of prefabrication is to achieve sustainable construction. This study aims to investigate the roles of prefabrication in fostering sustainable construction. The effectiveness of prefabrication on fostering sustainable construction was evaluated on the five aspects enlisted by the UK’s Green Construction Board: Waste, Water, Carbon, Materials, and Biodiversity. An industry survey was conducted in Melbourne, Australia for data collection. 200 questionnaires were sent via email or post to a variety of fields within the construction industry. Entropy ranking analysis was adopted to analyze the effectiveness of using prefabrication in construction. The results suggest that prefabrication is effective in reducing construction waste and sourcing energy efficient materials. However, the utilization of prefabrication was found unsuccessful in reducing carbon emissions during the construction process. It is suggested that proactive actions should be taken at the design stage to unleash the potential of prefabrication in construction.

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
