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.
