Crouch Waterfall completed three new Access for All Footbridge schemes for Network Rail on behalf of the Design and Build Contractor Balfour Beatty at Radyr, Llandaf and Machynlleth.
Completed in 2017, the new footbridges and lifts improve accessibility at the Railway Stations and allow for existing, substandard clearance, foot crossings to be removed.
Crouch Waterfall, acting as civil engineering and lead design consultant, formed a design team also providing electrical and telecommunications design services from GRIP 4 stage through to GRIP 6 including temporary works and design checks.
The new footbridges comprise; one main bridge deck span, lifts and staircases. The main bridge decks have a clear span of 12 to 13 metres and a minimum clearance to the railway of 5.2 metres.
They are designed in accordance with Design Standards for Accessible Railway Stations 2015 and the Technical Specification for Interoperability – Persons of Reduced Mobility (PRM TSI).
The footbridges are uncovered, with solid parapets incorporating LED lighting. Decks, staircases, link spans and supporting trestles are as per Network Rail Standard Footbridge Drawings. The lift shaft structures are project specific bespoke designs.
The bridges are founded upon reinforced concrete pad footings supported on either improved ground or reinforced concrete piles depending upon the location.
