What Octavius Infrastructure does

Octavius Infrastructure is a UK-based Tier 1 transport infrastructure contractor delivering highways, rail, local authority public realm, and modular parking solutions for public sector clients. The company operates through five service divisions — Highways, Rail, Transport Hubs & Car Parks, Transformative Regional Transport, and Regional Civil Engineering (ORCE) — with over 700 employees supporting 30+ active procurement frameworks. Its primary clients are Network Rail, National Highways, combined authorities, and councils including Cambridgeshire, Wiltshire, and Portsmouth, alongside enterprise customers such as South Western Railway, London Underground, and the University of Salford.

The company's technical capability rests on rail electrification and station accessibility (35+ Access for All schemes delivered), highways structures and junction improvements (M25, A46 Binley, A30 Crooked Billet), and a proprietary modular steel-framed car park system co-developed with SiderPark that is approximately 30% cheaper than traditional pre-cast concrete and 95% recyclable. Supporting digital assets include Sensat drone-based 3D digital twin mapping and NavTech radar for roadworks safety trials, though these are deployed as commercial off-the-shelf tools rather than proprietary platforms. The STOPThink! cultural development programme, with over £1M invested since 2011, institutionalizes safety practice across the workforce and supply chain.

Octavius generates project-based revenue through competitive framework agreements and direct contracts with UK government clients, with FY March 2025 turnover of £276.7M and pre-tax profit of £4.7M. The business was acquired by RSK Group from Sullivan Street Partners in November 2025 after a four-year PE ownership period during which the company scaled from a regional South England contractor into a national infrastructure player via organic growth and two bolt-on acquisitions (Navitas Engineering Group in December 2023 and R&W Civil Engineering). The current customer mix is heavily weighted to UK central and local government procurement channels, with framework-based repeat revenue providing multi-year visibility subject to public sector capex cycles.
