Whole Life Costings

Achieving Whole Life Cost objectives for five key elements of the London Bridge station redevelopment: Geothermal Piles and Heat Pump, Escalators, Lifts, Photovoltaic Cells and Platform and Concourse Lighting.

The London Bridge Station Redevelopment (LBSR), part of the £7bn Thameslink Programme, involved the complete transformation of the station to meet growing transport needs. The LBSR Sustainable Delivery Statement set out the way sustainability was to be achieved on the LBSR Project and included specific objectives from the Thameslink Programme Sustainability Strategy. This contributed to sustainability being a driving factor throughout the design and construction of the LBSR.

This case study relates to Objective 13 of the LBSR Sustainable Delivery Statement – To understand the whole life cost (WLC) implications of project and purchasing decisions. To assist with achieving that objective, the LBSR assessed the Whole Life Costing of the following five key LBSR elements:

  • Geothermal Piles and Heat Pump
  • Escalators
  • Lifts
  • Photovoltaic Cells
  • Platform and Concourse Lighting

Each case study presents a discussion of the options investigated, the savings (monetary or carbon) and other benefits, and key assumptions used.

These case studies also address Objective 15 of the TLP Sustainable Delivery Statement – Minimise the use of natural resources, water and carbon while increasing the life of materials and avoiding the generation of waste. The carbon reduction measures described, along with other energy efficiency measures that are were incorporated into the station design, resulted in the achievement of the 20% CO2e emissions reduction (from renewable energy sources) target set by Network Rail for the redeveloped operational station.
