A glimpse of our history

In the beginning...

Construction Marine Ltd was incorporated by Geoff Mortimer to undertake General Civil Engineering and Marine Civil Engineering works, operating from a small office with two colleagues, a great deal of ambition and a bank loan. Our initial client base consisted of British Waterways, British Rail, Yorkshire Water and more specifically Caledonian MacBrayne on the West Coast of Scotland.

Office space purchased in Leeds

In the early days we developed and patented a concreted fabric mattress system for use in scour and erosion protection which secured us several significant overseas projects. The work gave us momentum and continuity enabling us to purchase our first offices in Leeds.

Offices expanded to match increasing workload

Our continued growth led to the redevelopment of our existing offices, constructing a new enlarged building that incorporated workshops to fabricate our patented concrete injected mattress system.

Partnership contract secured

The construction industry fashion at the time was for more collaborative frameworks and CML were successful in securing a Civils Framework Contract with Railtrack. The framework led to the delivery of larger civils projects on the railway, including the significant re-development of Hessle Foreshore in Hull, involving the excavation and removal of over 20,000 tonnes of contaminated material adjacent to the River Humber, and installation of scour protection to the estuary river banks. One of a growing number of scour protection schemes CML were delivering nationally for Clients including Railtrack.

'The Soft Option'

CML develop and implement an innovative and sustainable river bank protection system consisting of willow spillings, palings, coir matting and planting of reed beds to provide sympathetic repairs in environmentally sensitive locations.

Railtrack Framework Contract secured

CML secures a framework contract on the railway network, delivering Civil Engineering works on the London North East Route for client Railtrack, the projects include a wide range of building and civil engineering operations. Due to the continued performance and commitment shown by our dedicated delivery teams, we have managed to continue to secure and expand our involvement in railway framework contracts to this day.

National Railway Heritage Award Winners

CML received National Railway Heritage Awards for the total refurbishment of three listed signal boxes at Hexham, Wylam & Haltwhistle, unique for their gantry construction over the line and using methodology that minimised disruption to the railway. Following the success at the Heritage Awards in 2003, CML went on to win another for the refurbishment of a listed signal box at Falsgrave in 2007, Beckingham in 2009 and Kirkham Abbey in 2011!

Underbridge Reconstruction for NYMR

One of the more challenging projects CML delivered at the time, was the reconstruction of Bridge 30 for the North Yorkshire Moors Railway in winter 2009. With significant access constraints, and a foot of snow on the ground for the core activities, this in one which our dedicated delivery team won't forget!

Expansion following award of Infrastructure Projects Contract

CML secure major earthworks and bridge reconstruction framework contract with Network Rail SNE, delivering a significant 5 year bank of work, consisting of repairs to rock cuttings and railway embankments.

New depot opened for minor works division

Following the continued expansion, and repeat success on the works delivery framework contracts for Network Rail, CML secure additional office and yard space in south Yorkshire from which to run the works delivery operation, moving to larger premises in 2014.

Additional regional offices opened

New satellite offices established in York and Colchester. Our York Office opened to service the day to day needs and collaborative nature of our RCDP Civils and Structures contract with Network Rail SNE. Our Anglia Office and Depot are opened to service the increasing demand from our Works Delivery Contract in East Anglia.
