Paddington, High Street Kensington, Gloucester Road, Triangle sidings
London Underground, Giffen Group
The works carried out on this project was originally planned and scheduled for approximately 4 months of engineering shifts. However, once London Underground had informed our Client that there was a works opportunity to work in a London Underground – Thales planned possession over the festive holiday season in which a 72 hour possession could be utilised OCL was asked if they could provide and procure the required labour and resources to deliver this project successfully.
Upon completion of surveys and the pricing of works. OCL was awarded the complete package incorporating 4 work sites with multiple tasks ranging from under platform and invert ducting systems, turning chambers and platform resurfacing to CMS and bespoke bridge works.
After the contract was awarded, OCL set up 4 supervisory work teams 2 weeks prior to possession taking place with strategic planning and careful preparation took place in close collaboration with the Client’s project team. All storage licences, hot works permits, material procurement, labour lists, work tasks and responsibilities were collaborated for implementation to be carried out successfully during the possession.
OCL had a total of 77 operatives working to complete these works over 6 x 12hr possession shifts over the festive season with all the required and correct certification in place. Many site meetings took place prior to possession dates and all operatives and their respective teams attended OCL offices for strategic planning meetings and safety briefings prior to commencement of works.
OCL not only delivered this complete project successfully, without issue or incident, but were able to procure and produce over and above that planned within the possession time. A number of PGI’s were carried out by London Underground during this possession of which OCL supervision and operatives were commended for correct procedures being carried out all times. Upon completion of this project a letter of ‘Congratulations’ and ‘Thank You’ was sent from London Underground and the Giffen Group project team.

OCL have carried out many civils and electrical projects for myself for over the past 10 years within the rail sector. They deliver what is required when needed and are trustworthy therefore I have no problem in recommending them.
I would like to thank all at OCL for a great job carried out by your staff over the 52 hour week end possession at Hockley station. The Pre planning meetings and OCL's early engagement with Braybrook really helped the smooth delivery of this project. A very professional job was done right first time, with no snags, we certainly look forward to using OCL in collaboration on future projects.
OCL Rail in conjunction with the Giffen Group carried out a number of varied installation projects at Neasden Depot the quality of their work and collaborative approach contributed greatly to the success in delivery of the projects involved with NDUP. I would have no hesitation in recommending OCL Rail for future works.
I have used OCL for over 8 years now not only as a labour agency but also carrying out contracted price work for the Giffen Group, I have always been extremely pleased with not only the efficiency of their service but the quality of their work.
I have worked with OCL Group on several rail projects. I have been very impressed by their professional, customer orientated approach to all aspects of works. They are a contractor who consistently deliver a high quality end product at a competitive price with attention to detail and I would not hesitate to recommend OCL Group for rail related projects.
