A new 5m span FRP Lifespan active travel bridge 4.5m wide designed & installed in the centre of Reading ready for the festival goers to use.
Lightweight & durable with a 120 year design life

The Mott MacDonald project engineers & our team member Steve Dunn provide information on the completed renovation of Redhall Weir footbridge in Edinburgh using a Lifespan resin infused FRP bridge deck solution - the first of it's kind in Scotland.

A new 16.5m span, sustainable FRP footbridge with a design life of 120 years incorporating a bespoke balustrade of marine-grade polished steel and infill panels with a protective rust patina.

Dates now available for CPD events in November, December 2023 and into early 2024

Colinton Dell is a steep-sided gorge and wildlife refuge on the Water of Leith, just north of the old village of Colinton on the outskirts of Edinburgh.
Today walkways and a cycle path take visitors to the ruined Redhall Mill and past Kate's Mill, where paper for the Bank of Scotland's first banknotes is said to have been made.
As a result of a Lifespan e news letter campaign in the autumn of last year we received an enquiry from the Mott MacDonald team in Edinburgh.

After several on line meetings and an on site visit we developed a solution for the Client Edinburgh City Council and introduced CRL Scotland to the project team as a specialist contractor that was capable of delivering the project.

Following a tender process in early 2023 CRL Scotland were awarded the project valued at circa £250,000 as reported in March of this year

The objective of the project was to provide a replacement deck for the existing Colinton Dell Rustic Footbridge with a design life of 120 years. The existing timber deck on the footbridge was in very poor condition and a new Lifespan Structures (FRP) deck was designed, manufactured & installed by CRL Scotland as a replacement so that the bridge can be re-opened in July of this year

Due to the very challenging location of the site the CRL team came up with a carefully thought out plan as to how they would remove the old bridge and be able to safely install the new Lifespan FRP deck sections.

Additional challenges for the team included a high pressure gas main adjacent to the existing bridge, the steepness of the Dell either side of the bridge location and that everything had to come through the famous Colinton Dell Tunnel.

The new Lifespan Structures FRP deck was designed in house to conform with a specification provided by Mott MacDonald. The new deck of approximately 28m span was supplied in 5 sections of 5.7m long x 2.5m wide and 65mm thick that are mechanically fixed onto the existing longitudinal steel beams, that are in good condition. A new 1.5m high galvanised steel parapet was also be installed.

The extent to which manufacturing-induced fibre mat misalignments compromise the structural integrity of pultruded GFRP road bridge decks is not properly understood. The problem is often critical at the web-flange junctions, which frequently contain the most severe misalignments and are subjected to high local moment-shear (M-V) combinations due to concentrated tyre load and also global vehicle load effects. Over the last 20 years, several GFRP decks have developed tyre load-induced damage of the top flange, due in large part to the prevalence of fibre misalignments.

Off site construction, means bridge production can continue all year round, and minimises installation times. This bridge replaces a corroded steel structure which had reached the end of its service life.

Lightweight FRP bridge deck for cycleway delivered. The 15m by 3m structure has been constructed off site and is being unloaded using a lorry mounted crane.  Low dead weights allow simplified foundations especially where poor ground conditions exist.

A small bridge, just 5m span, used to gain public access across a drainage ditch into a local nature reserve. The client was concerned that a traditional timber structure would have reduced durability due to damp environment, so selected the FRP option to reduce maintenance and subsequent whole life cost.  Its very well used by a lot of happy, wet and very muddy dogs!
