The contract, which becomes operational immediately, is based on availability and is underpinned by service level guarantees.
Babcock said that it would help Aggregate Industries reduce the cost of ownership of its HME fleet of more than 400 vehicles on 150 sites. This would allow Aggregate Industries to focus on its core operations of supplying heavy building materials to the construction industry.
Babcock chief executive Peter Rogers said: “This contract is particularly significant as it demonstrates that our unique whole life fleet management approach is being recognised by forward thinking organisations seeking competitive advantage."
Through its Mobile Assets business unit, Babcock operates contracts to manage more than 11,000 vehicles and 175,000 pieces of equipment worldwide. This includes a 10-year contract to manage Lafarge's HME fleets within the UK, US and Canada.
