Project Brief

Following the award of the £87 million contract for the design and build of the new Chiltern Railways route, between London Marylebone and Oxford, to the Carillion and Buckingham joint venture by Network Rail, Marshalls CPM were called upon to see if their Redi-Rock™ modular walling would suit the requirements of the programme.

The project called for a modular concrete block wall at Wolvercote Tunnel, which would be quick and easy to install, as gabion baskets had proven slow and difficult to build on another part of the project.

CPM Solution

The BBA approved Redi-Rock™ walling was suggested as an alternative as it had a proven ‘track’ record for Rail projects, such as this.

Marshalls CPM designed a solution for the embankment wall in their Cobblestone block walling which was approved by leading consultants Atkins and Network Rail and delivery schedules were agreed.

However, project changes were made which were redesigned by the Marshalls CPM, using the Redi-Rock™ engineering analysis software and approved by Atkins. Due to the ease in which the Marshalls CPM Redi-Rock walling solution can be installed, the delivery schedules were altered demonstrating the flexibility of the system.

Client Comments

Barry Mullen, Project Manager from the Buckingham Group said: “The assistance we have had from Marshalls CPM with the Redi-Rock walling, from the Sales team liaising with site schedules as well as the patience from the design team have really been appreciated by Carillion Buckingham JV”.
