Procurement Delivery

Sustainable materials and procurement

Influencing our supply chain to implement sustainable procurement strategies

Sustainable materials and sustainable procurement was the one of the most challenging areas of delivering Thameslink Programme. In the early stages our major station projects such as Blackfriars and Farringdon were successful in implementing sustainable procurement strategies however other parts of the TLP struggled to influence the supply chain.

The Blackfriars and Farringdon Station project teams and suppliers Balfour Beatty and Costain developed material use plans to identify their top materials and took action to make more sustainable choices in relation to those materials during the design process. The top materials were assessed against a set of sustainability criteria during the design phase which was integrated into the procurement process. At Farringdon the project team and Costain undertook sustainable procurement supply chain audits of key materials and measured their performance against the British Standard (BS8903) for Sustainable Procurement in Construction.

Improving our approach to sustainable materials and procurement

As TLP entered the latter stages of the programme a Responsible Sourcing Policy and procedure was rolled out across TLP and the supply chain to improve our approach to sustainable materials and sustainable procurement thus increasing our CEEQUAL scores.

At London Bridge responsible sourcing issues were considered much earlier in the design phase where the project team and Costain committed to a number of actions: 

  • Maximising the use of recycled and secondary aggregates in structural concrete 
  • Use of recycled materials such as ground- granulated furnace slag (GGBS) and fly Ash (PFA) as a replacement for ordinary Portland Cement (OPC) in the structural concrete 
  • 100% certified timber 
  • Responsible sourcing of structural steel, reinforcement and concrete 
  • Specification of materials not containing environmentally harmful.

Since implementing these improvements Thameslink Programme successfully delivered on its sustainable materials and sustainable procurement objective.

Case Studies

Sustainable Timber: Thameslink Programme

100% of Thameslink Programme's timber has been responsibly sourced, supporting Network Rail’s timber commitment. This case study summarises how this was achieved, its benefits and offers best practice advice.

Procurement & Commercial Strategy: London Bridge Station

This case study considers procurement and commercial strategy as part of collaborative planning, management and delivery of the Thameslink London Bridge Area Partnership works.

Early Contractor Involvement: London Bridge Station

This case study considers the importance of early contractor involvement as part of collaborative planning, management and delivery of the Thameslink London Bridge Area Partnership works.

Collaborative Processes: London Bridge Station

This case study considers the collaborative planning, management and delivery of the Thameslink London Bridge Area Partnership works.

Collaborative Forums: London Bridge Station

How the Thameslink Programme London Bridge Area Partnership works were collaboratively planned, managed and delivered.

Cable Management Sleepers

Developing a new design of cable manager sleeper, reducing the need for under track crossings, led to a significant cost saving for Thameslink Programme.

Lessons Learned Summary: Bermondsey Dive Under

Key lessons from what went well on the project including: integrated planning and relationship management, management of third party relationships, integrated working, change management, Value Engineering and scheme handback and close-out. The case study also looks at what could have been improved, including contract content, contract administration and rework/redesign costs, and proposes recommendations for future schemes.

Whole Life Costings: London Bridge station

Achieving Whole Life Cost objectives for five key project elements: Geothermal Piles and Heat Pump, Escalators, Lifts, Photovoltaic Cells and Platform and Concourse Lighting.

Self Delivery: London Bridge Station

Self-Delivery has enabled Costain to develop a model which enables a systematic and consistent approach in the deployment of resources, materials and controls on major projects. In this case study, James Elford, London Bridge Project Director, talks about the success of self-delivery during the station redevelopment project.
