Stoke Gifford IEP Depot

Client: Hitachi Rail Europe

The InterCity Express Programme (IEP) is a £5.7bn investment by the Department for Transport (DfT) to replace existing rolling stock on the Great Western and East Coast Main Lines. The IEP trains will be manufactured out of a brand new, state-of-the-art Rail Vehicle Manufacturing Facility (RVMF) in the North East and the project includes investment in new and refurbished train maintenance centres across the country.

Tasked with housing and maintaining the IEP fleet, the Stoke Gifford facility in Bristol plays a crucial role in ensuring the new rolling stock delivers the optimum level of service to fare paying passengers on the route.

NG Bailey’s work on the three-year project began when it was appointed by VolkerFitzpatrick in 2013 to assist in the design and planning phase for the £80m redevelopment of the site to build a technologically-advanced maintenance facility, improving operational efficiency and costs. Our specialist Rail and Engineering teams worked closely together to achieve this.

NG Bailey provided a range of mechanical and electrical services including design and build for the high voltage infrastructure, power, lighting, heating and ventilation.

The team also provided expertise to install all security and communication systems (such as the fire alarms, CCTV, intercoms and infra-red cameras), both internally and externally, to the maintenance shed, wheel lathe building, staff and cleaners’ accommodation, stabling, servicing roads and a carriage wash facility.

Our innovative lighting solution for the site’s buildings utilises LEDs for the external bollards and high-bay lights, which will result in a saving of over 200 tonnes of CO2 per year. The lighting solution was a key factor in helping the project to achieve its environmental goals and will also provide a £1m saving for Hitachi Rail Europe over the course of its 27.5year contract.

One of the biggest challenges for NG Bailey was ensuring the triangular site, which is approximately 16 ha (40 acres), formed by boundaries created by three railway lines, remained secure. We installed more than 64 high-resolution CCTV and infra-red cameras, along with an access control system, all operated via the site-wide IT network. This gives full surveillance of the boundaries, sheds and office areas, which can be monitored ‘live’ by staff at the central control centre.

The transformation of the 40-acre site was complex and necessitated detailed planning and co-ordination with everyone on site to keep the plans on track.

One of the key aspects has been NG Bailey’s ability to produce some of the new systems via its offsite manufacturing facility. Enabling completed systems to be delivered directly to site, saving a significant number of man-hours and, therefore, reducing the overall project time and the resources required on site. The benefits of offsite manufacture also included improved quality by allowing the distribution board sections to be assembled under factory conditions. Equally importantly, it also cut safety risks by reducing the number of workers on site.

The Stoke Gifford project has been recognised as an example of best practice in the construction industry, receiving one of the highest Considerate Constructors Scheme scores in the UK.
