Sullivan Street-backed Octavius snaps up Navitas

Navitas is a consultancy which provides railway electrification, engineering and design services to infrastructure supply industries.

  • Navitas is Octavius’ second bolt-on acquisition in 2023
  • Sullivan Street Partners focuses  on primary mid-market buyouts
  • Sullivan Street invested in Octavius in 2021

Sullivan Street Partners has completed the purchase of Navitas Engineering Group through its portfolio company Octavius Infrastructure.

Navitas is a specialist consultancy which provides railway electrification, engineering and design services to infrastructure supply industries. London-based Navitas is working on projects such as the design of the Crossrail station at Whitechapel, the review of the electrical safety of the Docklands Light Railway and a technical investigation of the South-West Railway.

Octavius will benefit from Navitas’ expert toolkit, which includes services such as technical standards and specifications, detailed design work, and experience of conducting tests and studies, according to a press statement.

Navitas is Octavius’ second bolt-on acquisition in 2023. The company acquired R&W Civil Engineering in July.

“We are pleased to welcome Navitas into the Octavius family of companies,” said Layton Tamberlin, managing partner at Sullivan Street. “Octavius is well placed to support two very different acquisitions in a seven-month period, attesting to the work done over the last two years, and our hands-on development approach.”

Sullivan Street, based in London, is a value-led buyout firm that invests in the lower mid-market across various sectors. It takes ownership or controlling stakes in companies through investing £20 million to £50 million of equity.

Octavius Infrastructure is a transport infrastructure and civil engineering business focused on railways and highways. The company is based in Surrey, UK.
