The deals will see the firm provide a range of services, including project management and support, cost advisory and site supervision.
Professional services contracts have been secured for schemes at the ports of Immingham, Southampton, Lowestoft and Plymouth, as well as a further project in Newport in Wales.
Immingham Eastern Ro-Ro terminal in North East Lincolnshire is a major £100m project involving the construction of a new Ro-Ro facility within the eastern side of the port, which will include the creation of two new harbour berths.
On this project, which is set to complete in 2025, Mace will provide contract administration, cost management and scheduling services.
Mace will carry out similar duties and site supervision at a Port of Southampton project focused on the expansion of the existing container-to-rail facility in the Western Docks.
The project will involve an expansion of the existing rail terminal at the dock alongside extending the existing rail loading platform.
At the Port of Lowestoft, Mace is supporting the Lowestoft Eastern Energy Facility project to develop the port’s Outer Harbour to provide an additional three service operation vessel berths and six crew transfer vessel berths for the offshore energy industry.
At Millbay Ferry terminal in Plymouth, Mace will suport a major upgrade of older existing infrastructure. This includes creating a new passenger boarding bridge system to connect vessels with the terminal building, updating the existing Ro-Ro ramp and refurbishing part of the historic West Wharf.
Sean Gray, director of transportation, Mace, said: “It’s been an exciting time for our ports team, with these latest wins marking a sizeable expansion in our portfolio.
“Our team will combine their practical delivery experience in the transportation sector with localised knowledge to provide fresh thinking to deliver the projects successfully. We are looking forward to playing our part in delivering these projects which will leave a lasting positive legacy for their users and wider communities.”
