Project Details

The 12m high, heavily reinforced abutments and wing walls are supported on reinforced concrete pile caps. The structure is situated within 1m of the Rail corridor making the interface with Network Rail particularly challenging.

The Design and Prefabrication of Rebar elements has been key to improving programme and reducing Possession working time on the Project.

Complex access scaffolds have been designed, managed and constructed by CCS scaffolding.  We have again undertaken the design, management and delivery of temporary works and cranes on this section of the project.

Sian has undertaken the particularly challenging task of managing the ALO rail interface with respect to all plant including MEWPS, cranes and concrete pumps in particularly tight and restricted work areas.
