The innovative and large-scale project connected the new energy centre to both Terminal 2 and Terminal 5 by four miles of underground services, futureproofing energy requirements and providing back up supplies as needed.
An innovative and large-scale project, the energy centre at Heathrow Airport is one of the largest combined biomass and natural gas plants in the UK. The project connected the new energy centre to both Terminal 2 and Terminal 5 by four miles of underground services, futureproofing energy requirements and providing back up supplies as needed.
BakerHicks provided multi-disciplinary design services on the project, developing the design from concept, through scheme and detailed design to completion.
Design management and lead consultant role
Leading on building services (mechanical and electrical), civil and structural engineering and architecture
3D modelling and integration of specialist plant and equipment
Planning and construction support, including site quality control visits, preparation of as-built drawings and working with the contractors and suppliers to ensure asset management integration and ‘bring in to use’
Studies introducing additional capacity into the system and exporting to other Heathrow projects
With underground services feeding both Terminal 2 and 5, the project required significant services rerouting and coordination. Our engineers worked closely with BAA to understand the performance requirements of the system and evaluate the technology options available. We introduced an innovative approach to installing the two 600mm diameter pipes under the southern runway within the cargo tunnel that would provide the connecting services. By using a total encapsulation or removal approach we created a uniform platform beneath the road, positioning the pre-insulated pipes through single slots in the road using a hydraulic ram. This approach provided significant costs savings, reduced the construction programme by several weeks and provided a much safer environment for construction and ongoing maintenance.
Sustainability and the provision of renewable energy were key project drivers, The energy centre houses a combined biomass and natural gas CHP, helping reduce the airport’s environmental impact.
The project delivered cost, time and energy savings through innovative design, which was recognised in its shortlisting for Construction News Awards ‘Project of the Year’.
