Project delays and cost: stakeholder perceptions of traditional v. PPP procurement

Purpose – This paper aims to investigate the impacts on project delay from the perspective of construction stakeholders. Specifically, it aims to make a comparison between traditional procurement based on standard contract forms and private/public partnerships (PPPs), for the procurement of public sector projects in Scotland.Design/methodology/approach – A structured questionnaire survey was used to elicit perceptions of seven delay impact groupings. Response data were analysed using hypothesis tests to observe perceived differences among these groupings, in respect of each procurement method. Follow‐up semi‐structured telephone interviews further explored stakeholders' views and broader issues.Findings – Significant differences of perception were identified between the impacts of: client, contractor, designer, financial, labour and material related delay factors. These were felt to have greater “delay potential” under traditional vis‐a‐vis PPP procured projects. There was no significant difference among ...
