Heathrow Airport Energy Infrastructure
Future-proofing the energy requirements of Heathrow Terminal 2
Interfacing low-carbon technologies and multi-fuel CHP, delivering CO2 savings
Integrated design and build solution
Shortlisted for Construction News Awards ‘Project of the Year’ 2013
Design To Concept
An innovative and large scale project, the new energy centre at Heathrow Airport is one of the largest combined biomass and natural gas plants in the UK. It saw the new energy centre connected to both Terminal 2 and Terminal 5 by approximately four miles of underground services, futureproofing energy requirements and providing a back-up supply for Terminal 5.
BakerHicks provided multidisciplinary design services on the project, developing the design from concept, through scheme and detailed design to completion. Key services included:
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 built-as drawings and working with the contractors and suppliers to ensure Asset Management Integration and Bring in to Use
Studies looking at 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 were able to create a uniform platform beneath the road, enabling pre-insulated pipes to be moved into position through single slots in the road using a hydraulic ram. This approach provided savings of in excess of £150,000, took several weeks off the construction programme and provided a much safer environment for construction and ongoing maintenance.
Sustainability and providing significant renewable energy contribution were key requirements of the project. The energy centre houses a combined biomass and natural gas CHP, helping reduce the environmental impact of the airport. The generated power is monitored, enabling the renewable energy power component to be recorded so CO2 savings can be established, helping BAA in achieving its targeted 34% CO2 reduction from buildings and infrastructure by 2020.
The project delivered cost, time and energy savings through innovative design. This was recognised in the project being shortlisted for ‘Project of the Year’ in the Construction News Awards 2013.
