Purpose – The construction project is implemented under uncertainty environment, and the product of construction is very complex. Selecting a project delivery system/approach is a critical task, which determines the project schedule, quality and investment objectives. The purpose of this paper is to propose a decision-making model for the selection of project delivery system which is based on information entropy and unascertained measure model. Design/methodology/approach – A decision-making model based on information entropy and unascertained set is employed to select project delivery approach. In order to overcome the subjective evaluations from the experts, the theory of “entropy weight” is applied to modify the experts’ subjective weight. The multi-attribute unascertained measure decision making is fitted to deal with the uncertainty information for selection of project delivery system. Findings – The proposed methodology is more comprehensive compared with the previous work, especially in the uncertainty environment. Research limitations/implications – There is some further work that should be considered, such as how to deal with the imprecise and subjective information given by the experts; how to determine the weight of the experts’; finding a set of importance factors influencing the selection of a delivery system is a complex task to further research. Practical implications – The proposed method can help the construction owner to select a most fitted project delivery system of a construction project. Originality/value – A new approach to select project delivery approach is proposed based on information entropy and unascertained set.

Delivery Approach

In the current competitive and complex business environment, innovation in the construction industry is vital. In this sense, integrated project delivery is an emerging delivery system for construction projects; however, implementing this system requires some enablers to enhance its implementation. Until now, no study has been conducted to identify what enablers can lead to proper integrated project delivery implementation. Therefore, this study aims to identify and to classify integrated project delivery implementation enablers. In this study, a comprehensive list of integrated project delivery implementation enablers has been developed using an in-depth literature review. Besides, integrated project delivery project managers, employers, consultants, contractors and engineers participated in a survey. The obtained results were analysed using exploratory factor analysis method. Thus, the study findings illustrated that organisational enablers are considered essential enablers, followed by environmental, contractual and technical enablers. The significance of this research is the identification and classification of integrated project delivery implementation enablers, which will provide valuable information to develop integrated project delivery implementation strategies. Additionally, the results of this study can be a proper roadmap to support developing countries to adopt the integrated project delivery approach for project developments.

This study investigated the use of e-Procurement in selected construction firms in Oyo state, Nigeria. The data were derived using a well-structured questionnaire survey involving 104 respondents. Descriptive statistical and correlation analyses were used to analyze the data. Findings show that the use of electronic procurement in the selected construction firms for carrying out procurement function is high with majority of the professionals affirming the use of the system, the four categories of e-Procurement used were e-mail, static websites, web.2.0 technologies and portals that have capabilities of supporting the execution of functions limited to intra and inter firm communication and exchange of project information and data. Consequently, between 84 percent and 76 percent of the respondents used these e-Procurement technologies for communication of information, exchange of bill of quantities, project reports, CAD drawings and project specifications. Consequently, factors with the highest positive impacts on the use of these technologies in the firms were the speed of transactions, lower transaction cost and ease of use. The study implies that the selected construction firms in Oyo state Nigeria predominantly use e-mails and websites to support the execution of pre-award phase of construction procurement. Finding also shows that there is positive relationship between e-Procurement (e-Notifying, e-Exchange, and e-Submission of bid) and Project delivery. The study suggests that to accelerate the rate of uptake of e-Procurement and maximize its benefits in the Nigerian construction industry, there is a need to improve the quality and quantity of ICT infrastructure across the country; and to embark on aggressive enlightenment campaigns, training and skill development programs in the use of e-Procurement in the construction industry in this country.
