Extant research in construction supply chains focuses on new asset construction projects, with little addressing longer duration asset and network renewal and maintenance programmes. The purpose of this research is to address a gap in construction supply chain research, and consider if supply chain integration is applicable in long-term work programmes in civil infrastructure. This qualitative research draws on data provided by semi-structured interviews with contractors, clients, sub-contractors and materials providers from two roading network case studies. The data were analysed using ethnographic content analysis in three stages, which generated propositions aligned to aggregate dimensions identified in the literature. The findings suggest that there is an underlying demand and value for increased integration, and a willingness and trust amongst the focal actors to integrate more with upstream and horizontal partners. However, implementation would be hindered by the focal actors’ limited capabilities and maturity in supply chain management and supply chain integration. The research concludes that focal actors, delivering long-term programmes of planned and response works, could adapt prevailing supply chain methodologies to benefit from increased integration. The research contributes to knowledge through an increased understanding of supply chain integration considerations in asset maintenance and renewal programmes.
