    Moulsford Railway Bridge Viaduct, Oxfordshire, UK

    GRP Access Structures

    Project Overview

    Known locally as Four Arches, this Grade II* listed structure consists of two parallel bridges or viaducts carrying the London-Bristol railway line. Dura Composites supplied a range of GRP access structures to contractors working on behalf of National Rail to carry our repair and maintenance works to Moulsford Railway Bridge.

    Repairing historic structures with minimal disruption.

    Dura Composites market-leading GRP (FRP) solutions played a crucial role in helping to maximise the lifespan of this Grade II* listed viaduct in South Oxfordshire.

    Previously, to carry out an inspection, (either planned or for an emergency), both tracks on the viaduct had to be blocked which caused significant disruption and required possession of the track. Purpose built inspection gantries made from lightweight and high strength GRP Dura Profile and Dura Grating were supplied by Dura Composites, and were cleverly hidden from view to ensure the aesthetics of the structure were not marred.

    Lighter than steel, GRP puts less stress on the structure.

    Weighing up to 50% less than the equivalent steel, Dura Profile is a high performance structural solution which is corrosion-resistant, easy to handle, non-conductive and economic to transport. At Moulsford Railway Bridge it was used alongside Dura GRP Access Ladders to create the hidden gantries and maximise durability and safety.

    Dura GRP Ladders can be supplied in any specification up to 6 metres and can be equipped with safety cages and walkthroughs. The flooring used for the gantries was market-leading Dura Grating – a nonslip flooring system which is durable, lightweight and chemical and corrosion resistant and which can be easy cut on site using standard power tools and requires no hot works permits.

    Finding the right solution to the difficult problem of inspecting and maintaining a structure of such national importance was paramount. We selected Dura Composites on the basis of their expertise in the sector and the service level they provide. The solutions for Moulsford Viaduct were fully fabricated by Amco on site, proving how easy they were to work with and ensuring that the job was completed in a timely manner and to a high standard. The Amco team were delighted to win a prestigious Network Rail STAR Award for this project in recognition of our commitment to health, safety and environmental risk control.
