Penmark – London Bridge Station Redevelopment
ProQS Professional Quantity Surveyors working with construction firms in London to deliver cost advice and management for London Bridge station redevelopment
CLIENT: Penmark – London Bridge Station Redevelopment
LOCATION: London Bridge Station

Project details:

This particular quantity surveying project related to the redevelopment of London Bridge Station by Costain Limited as the tier one supplier. The commission was for part of the project working with Penmark Limited on the £110m development of the platform and canopy works, providing commercial management services to develop and manage a team of five surveyors.


The London Bridge station was a complex project, and the development of the platform and canopy came with a great deal of responsibility for the client and ProQS. We were required to develop and manage strategies for budget forecasting and cost reductions, then ensure contractual compliance, accountability and continuous application of the client policies.

Not only was the role about building operational efficiencies on one element of the project, it also involved strengthening integration with the operational obligations for the wider project. Further responsibilities were required to procure and inspect materials off site, checking this was done in accordance with the contract before purchasing the materials the materials – a responsibility which was part of our appointment.

We also recommended and undertook audits of supplier’s rates and prices to demonstrate claims provided value for money to Costain and their client.

Complexities of the project:

  • The site environment was changing daily.
  • The project involved meticulous management of a strategic partner, whose scope was critical to the program.
  • Maintaining the budget.
  • Our work included valuing 1,000 historic variation claims achieving cost certainty.
  • Annual forecasts were required to be fully prepared whilst developing and implementing improvements.
  • Using the clients’ multifaceted information technology system for managing the project finances, without training provided.


The project reached a very strong and positive conclusion with 5 platforms being handed over, and forecasted, ready to be constructed under budget. A £70m subcontract negotiation and final account, the settlement of £4m of claims with significant saving on the budgeted amount, and 1,000 of outstanding variations positively assessed. We were also very proud in being able to support and develop a talented member of staff who was subsequently promoted within the company.

Kieron has a demonstrable experience in delivering complex major projects. Over the time we worked together at London Bridge, I found Kieron to lead by example, always with the end goal in mind. He was a valued member of the Commercial team, who always sought collaborative solutions whilst not being afraid of doing the hard work.
