Impact of familiar collaboration on construction project quality: perceptions from clients and contractors in Singapore's construction industry

Due to the fragmented and complex nature of the construction industry, many countries, including Singapore, have progressively encouraged greater collaboration amongst major stakeholders in the industry. It is hoped that doing so will result in an increase in the quality of construction projects. Given the long duration of typical construction projects, it is plausible for collaborating parties to develop close and personal relationships. In recent years, corruption cases arising from familiar collaboration have caught the public's attention. This study seeks to better understand familiar collaboration and its adverse impacts on the quality of construction projects.

A mixed research method was adopted, with a questionnaire survey distributed to 32 respondents representing client and contractors. This was followed by interviews to validate the survey findings.

The findings suggest that, when there is a lack of surveillance, familiar collaboration is likely to lead to favouritism and dishonesty, which can have an adverse impact on the quality of construction projects. The findings additionally suggest that value for money, conformance to specifications and fitness for purpose are the main aspects of quality that are likely to be adversely affected by corrupt practices bought about by familiar collaboration.

In this paper, these relationships are described using the term familiar collaboration. Strong and intimate relationships of this type may lead to a danger of parties committing corrupt practices. This study is one of the very attempts seek to better understand familiar collaboration and its adverse impacts on the quality of construction projects.
