Effect of adoption of relational contracting practices on relationship quality in public projects in Singapore

Purpose - The purpose of this paper is to investigate relational contracting (RC) practices that give rise to higher quality interpersonal relations between these pairs of stakeholders at the end of public projects: clients and contractors; contractors and consultants; and clients and consultants. It developed models to predict the level of quality of interpersonal relations between the stakeholders at the completion of public projects. Design/methodology/approach - Using a set of questionnaire, data were collected from randomly selected construction industry practitioners who have had experience in public projects in Singapore. The data were analysed to identify association between the use of RC practices and quality of interpersonal relations between stakeholders. In-depth interviews with experts were conducted. Findings - It was found that when certain RC practices were adopted to a larger extent, public projects also have significantly higher quality of interpersonal relations between clients, contractors and consultants. Three mathematical models were developed to predict the relationship quality between stakeholders at the end of the public project. Research limitations/implications - The limitations include the subjective nature of the Likert scale that was used in answering the questionnaire survey and the limited number of interviews. The effect of existing good relations among stakeholders was not taken into account. Practical implications - Suitable RC practices for adoption by public clients, contractors and consultants in public projects are recommended. These include developing deeper mutual trust and understanding, sharing project information, and having real gain-share/pain-share among contracting parties. Originality/value - RC practices that are significantly associated with relationships among contracting parties in public projects in Singapore are uncovered. Contracting parties may use the recommendations to help enhance their relationships with one another in a public project.
