Costain Group PLC, a UK infrastructure business, has achieved a significant milestone in its gas distribution network upgrade program with Cadent. The company is replacing approximately 340km of gas main line each year in Cadent's East of England network, the largest of Cadent's five gas networks across the UK. Through collaborative efforts with Cadent and supply chain partners, the scheme is on track to see 380km replaced by the end of the financial year, 31 March 2024. Costain surpassed its 340km-per-year target more than a month ahead of schedule, attributing this success to the application of agile operational processes around planning, program management, reporting, and control, which have led to efficiency gains. This achievement showcases Costain's commitment to delivering on its targets and its ability to drive operational efficiency in infrastructure projects.
