Regulatory framework for unsolicited PPPs in infrastructure developments: barriers and strategies

Purpose Unsolicited proposals (USPs) play a significant role within public–private partnerships (PPPs) as a procurement method for initiating infrastructure development projects. Despite their potential effectiveness, USPs are often viewed as controversial due to deviations from conventional public procurement principles. To address these issues, numerous countries have established regulatory frameworks to align USPs with standard procurement practices. However, persistent challenges in implementing USPs have hindered the evolution of more robust regulatory mechanisms. This study aims to bridge this gap by developing strategies to enhance the regulatory framework for managing USPs in infrastructure projects. Design/methodology/approach This study adopted a qualitative research paradigm, using semi-structured interviews with 12 professionals within the Sri Lankan construction sector, all of whom possess substantial expertise in the realm of USPs. Subsequently, a thematic analysis method was used to analyse the collected data and derive findings. Findings Notably, eight challenges that arise during USPs implementation were identified along with 28 strategies to overcome each challenge. Accordingly, a strategic framework has been presented with rectified challenges and strategies to overcome those challenges. Originality/value This investigation delineates strategies for instituting a regulatory framework aimed at overseeing USPs. The insights derived from this study serve to guide policymakers and industry practitioners in refining public procurement legislation, fostering requisite adaptations conducive to the efficacious incorporation of USPs. Such enhancements serve to empower the private sector, fostering a milieu conducive to the generation of competitive and innovative proposals.
