Tir Phil Station

Balfour Beatty Rail

Project Type:
Permanent Works, Temporary Works

Crouch Waterfall was approached by Balfour Beatty to support them in their design and build of the station improvement works at Tir Phil, located within the welsh valleys. As part of a suite of station improvement works, both platforms are being made compliant for wheelchair access. This requires installation of a large (c.100m long) steel ramp on Platform 1, in place of the existing steep non-compliant ramp.

Due to the topography, geology and existing structures and services, is was immediately apparent that traditional piled footings would not be possible. Additionally, the use of shallow footings held considerable risk, not only with the potential for soil creep, but also in the temporary works required in order to allow the installation of shallow footings.

Crouch Waterfall designed a series of staged concrete footings at sufficient depth and with sufficient mass to prevent movement from soil creep. The design of the footings themselves, while complex, was standard/typical.  However in order to install the footings, the excavation of the slope for the footings needed to be supported in a temporary condition, without there being any impact on the historic retaining structures, buried services or the operation rail platform.
