Suitability of public-private-partnership procurement method for road projects in Sri Lanka

Abstract

PurposeGovernments of many developing countries that are unable to develop their infrastructure in order to obtain financial resources prefer to establish public–private partnerships (PPPs) for providing the much-required infrastructure. Time is thus opportune for Sri Lanka, which is also a developing country, to make use of PPPs to develop its road network. The purpose of this paper is, therefore, to identify the PPP models that suit road construction in Sri Lanka.Design/methodology/approachThe study used a mixed approach. The characteristics of road construction, procurement selection factors to be considered in road construction, and the different PPP models that can be used for such procurements were identified through a comprehensive literature synthesis. The findings were validated using expert interviews. A questionnaire survey identified the PPP models that suit road construction in Sri Lanka. The most suitable model among them was identified by ranking the PPP models using procurement selection factors.FindingsBuild–Own–Operate–Transfer was identified as the PPP model that best suits road construction in Sri Lanka. However, investors may not find it attractive because of its high payback period, a result of the low traffic volume in Sri Lanka. Therefore, a PPP model that involves road construction alone will not be feasible in Sri Lanka. It will have to include the construction of other infrastructure as well.Originality/valueThe study identifies a PPP model that best suits the road construction projects in Sri Lanka.
