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.

Factory production reduces construction times

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.

Composite Footbridge

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!

Introduction to FRP Bridges

We are currently offering our CPD presentation called 'Bridging the Gap', if this is of interest please get in touch.  The presentation is particularly suited to local authority bridge engineers and consulting engineers who provide bridge services. The presentation will covers the following topics to introduce the concept of using FRP materials rather than steel, timber and concrete.  - Introduction to FRP composites
 - History of FRP composites in construction
 - Recent case studies
 - Benefits
 - Cost comparisons with traditional materials
 - Environmental benefits
This presentation will inform attendees of the significant benefits so that the FRP composite material option can be included in appropriate future proposals for the benefit of clients.
