Specialist marine contractor delivers unique solutions for repairing and maintaining structures in water

The structures within the rail network infrastructure; particularly rail bridges over water, are engineering marvels that have been connecting communities for centuries. These structures not only serve as vital transport links, but also showcase the creativity and ingenuity of the engineers who design and build them. However, the rail industry has challenges. One of the industry’s biggest obstacles is the need for infrastructure development and modernisation. As well as ageing infrastructure, climate change has also had a detrimental effect on inland and coastal rail infrastructure. Many railways in the UK require significant investment to upgrade and maintain them properly.

Kaymac Marine and Civil Engineering Ltd. has made it its business to deliver water infrastructure solutions in ways which minimise disruption to rail services. Demonstrating its continued commitment to being at the forefront of developments in this discipline, Kaymac has sourced and trialled new technologies and innovative methods to ensure that it has the most productive and effective ways of managing transport projects, even highly regulated and time-sensitive ones. Kaymac guarantees the best results for clients whilst reducing downtime for users.

Multidisciplined team
Over the years Kaymac has grown significantly and now delivers multidisciplined schemes across waterway infrastructure and the UK rail network. Due to its experience and expertise in controlling water flow, Kaymac can deliver unique turnkey solutions to construction challenges within watercourses. This has enabled Kaymac to integrate its offering, and work as a specialist subcontractor on larger schemes to Network Rail Tier 1 delivery partners as well as Principal Contractors.

In recent years, Kaymac has repaired and maintained some iconic bridges situated in tidal and fluvial environments. The Kaymac team have delivered complex scour protection projects that have involved temporary work designs, installations, and highly skilled, multidisciplined construction teams that include Commercial Divers, plant and skilled civils operatives to deliver the permanent scour repair and protection works within watercourses.

Going off track and winning awards
Kaymac is not just a rail engineering specialist and has an equally impressive portfolio of work and clients in civil engineering, coastal and inland waterways, confined space services and diving operations. To give an indication of how diverse and specialised its areas of expertise are here are a couple of examples of award-winning projects outside of rail engineering. On the coastal engineering front and energy sector, Kaymac was contracted to install a fish deterrent system at Pembroke Power Station in West Wales, which is the biggest gas-powered power station in Europe, it received an award for ‘Excellence’ and a plaque to commemorate the inauguration of the power station.

The Swansea Tawe Barrage project comprised of scour protection for the quay wall above and below the waterline, refurbishing the main barrage lock gates and installation of new post and rail fencing. The work was undertaken with a multi-disciplined approach and was completed on schedule and within budget, which resulted in Kaymac winning a prestigious ‘Best Project’ award in 2019. In 2021, following the unprecedented flood conditions experienced, structures across the UK’s watercourses had been left in dilapidated states, with asset owners determining whether repairs can be undertaken safely, or in some cases whether a full structural demolition is required.

The Grade II listed structure at Escob West was such a structure earmarked for demolition before Kaymac was given another great opportunity to showcase its innovative approach to solving complex in-water engineering problems. Kaymac saved the bridge with a creative temporary works and repair solution that saw them win the National Bridges Awards 2021 Category: The Bridges Award for New Life – Project Below £5 million. Most recently, Kaymac won a Team100 award for quality for its involvement in the pintle replacement on the £34 million flood defence scheme at Tilbury Docks.

The future is bright
Kaymac will continue to offer turnkey innovative marine civil engineering solutions to Private and Public sector clients UK Nationwide. The company recently secured its place on Lot 10. Of the £1 billion South West Wales Regional Civil Engineering Framework which has secured a healthy pipeline of work over the next four years.

Rhiannon Crees-Moore, Business Development Director, Kaymac Marine & Civil Engineering Ltd: ‘Out of the five contractors that tendered for the Lot. 10, there were just two successful bids; We are extremely proud of the hard work and dedication that has gone into this achievement, and we couldn’t have done it without the support of our amazing team. As a first generation framework contractor, we have had the privilege of working with some incredible clients over the years, and we are grateful for the strong relationships we have built with them. We look forward to continuing these partnerships and providing exceptional service and support to our clients. At our core, we are committed to delivering excellence in everything we do, and this latest contract win is a testament to our unwavering commitment to quality and customer satisfaction.’

Following the UK fisheries embargo, construction work In Salomon Rivers will commence in April and continue through to October, and Kaymac is very much looking forward to another exciting summer delivering high-profile scour protection projects in collaboration with Network Rail Tier 1. Contractors and Consultants.

As well as project delivery, Kaymac will be exhibiting at the Flood and Coast Exhibition at Telford International Centre on the 6, 7 and 8 June.
