The aim of the Liverpool Street Station roof replacement project is to refurbish the existing roof by replacing the current life expired GRP and Georgian wire glass roof panels.
In order to replace the GRP panels, temporary works will be required to access the internal roof structure whilst also providing a safe working platform to undertake the necessary works. Works needed to be carried out safely, in line with Network Rail standards and with little impact on the daily operation of the station.
The safe working platform required to be built for the works will block both natural and artificial lighting above it and affect the station information systems (SISS). The worksite above the deck will also require lighting, power, and fire alarm system. In order, for the station to continue its operation, a new lighting system serving the public affected areas is required, together with provision for adequate power and lighting for the worksite. The design of the lighting and distribution layout has to take account of the RDG Engineering design and sequencing to ensure the station public lighting is maintained operational at all times.
We completed an option appraisal, GRIP 4 design, detailed design GRIP 5, and issued a completed AFC pack for construction.
Camden Winding Vaults
The Camden Winding Vaults are a Grade II* listed structure and were built to house two large steam engines and winding gear used to pull trains up the incline from Euston, on the London-Birmingham Main Line. This was to avoid disturbing residents with the noise of steam-hauled trains.
As part of the HS2 route, the TBM tunnels from Euston Station will pass in close proximity to the existing vaults. As such there may be a need to carry out some mitigation works and there is a requirement to monitor the vaults during the tunnelling works. The project was to provide access to the underground structure to facilitate the initial surveys and investigation works, as well as ongoing monitoring works. The purpose of the project is to provide safe access to the underground structure to facilitate the initial surveys and investigation works, as well as ongoing monitoring works. In addition to level access scaffold the vaulted area is to be provided with lighting, ventilation, pumped drainage and fire detection system.
Temporary site lighting was provided by 110V linear LED luminaires, selected from Blakley Electrics, i-Site Intelligent Lighting System using pre-wired 3-core 4mm2 LS0H cable with Flori-67/3P sockets for additional temporary lighting where required to boost illuminance levels for the inspection purposes. Power supply is also required for a drainage pump to stop flooding of the vaults. Fire alarm and a ventilation system are also provided within the vaults to ensure safety of personnel carrying out inspections. We also provided for Form C temporary works design covering the MEP services.
Station Works, Stratford Upon Avon
CBG have undertaken two schemes at Stratford-Upon-Avon station, a site that facilitates the travel for over 4 million tourists that come to see the home of William Shakespeare each year.
Initially CBG’s employment helped facilitate the works required for the ‘access for all’ scheme, providing a footbridge, staircases and lifts to allow all passengers, regardless of disability, access to every platform. The works included providing electrical lighting and power including LED handrail lighting, mechanical ventilation and heating for the new build works as part of the F001, F002 and F003 design. Technical support was also provided at site stage.
Subsequent to these works, CBG were employed in 2014 by Network Rail to assess and renew the current M&E services throughout the station. These works included: lighting design, electrical cable loading and calculations, and assessment of the existing heating. F003 design was completed DRNs incorporated and AFC package issued.
Paddington Lawn Retail Suite, London
A complete overhaul of the Grade I Listed Paddington Lawn retail suite comprising the thorough refurbishment and extension of facilities for 22 individual retail units and common parts concourse areas.
Retail outlets include notable major UK retail chains such as Boots, Fat Face, Accessorize and Thomas Pink.
CBG were engaged to upgrade the existing infrastructure, including a new 1000 kVA substation, busbar route, ventilation and domestic water services to accommodate the increased capacity within the constraints of the existing building. CBG duties also covered the M&E for GRIP 5-8 stages, detailed design, site support and AS Built information.
The successful completion of this project included presentation of the new scheme to Network Rail executives and the production of tenant fit out data sheets for each of the 22 retail tenants. This project has enabled the Paddington Lawn project to become a showcase for Station retailing with the best possible customer experience.
Clapham Junction Station, London
CBG Consultants were involved with the major refurbishment of numerous stations for South West Trains as a part of the NSIP Scheme which included works at Clapham Junction Station.
Our contribution included mechanical and electrical design services which covered initial site surveys and a site surveys of existing mechanical and electrical services, through to design and site support. The Clapham Junction project consisted of the creation of a new entrance to station from St John’s Hill involving design of heating, water, air conditioning, utility supplies, internal and external lighting, power, CIS provision, power to ATMs and passenger Gates.
