Join a major £30m+ upgrade to a key Waste Water Treatment Works in Buckinghamshire, part of the AMP8 investment cycle. This is a critical infrastructure project delivering clean water to thousands of homes — and it’s just one piece of a secured long-term pipeline of work.
The Role
As Senior Quantity Surveyor, you’ll play a hands-on commercial role from day one — reporting into the Managing QS and Commercial Manager. You’ll be trusted to manage subcontractor accounts, identify cost-saving opportunities, and lead the full commercial lifecycle of this flagship project.
You’ll be working under an NEC3/4 Option C contract on a high-profile scheme that blends complexity with long-term stability. Ideal for someone who thrives on detail, sees risk as something to be managed (not avoided), and enjoys ‘finding the money’ others might miss.

Manage subcontractor packages from procurement through to final account
Own the change management process — including compensation event pricing
Issue notices and applications in line with the NEC contract
Produce CVRs and support forecasting across the commercial team
Work closely with engineering and delivery teams to ensure accurate site records
Identify risks and opportunities that impact project margins
Build strong client and subcontractor relationships for long-term benefit
Support and mentor junior commercial staff when needed
What You’ll Bring
Proven experience with NEC3/4 Option C contracts
Background in Water or broader Civil Engineering infrastructure
Strong commercial awareness with a forensic eye for contract detail
Experience managing high-value subcontract packages
Capable communicator and team player – comfortable influencing stakeholders
Working knowledge of Oracle, CEMAR, or similar systems (preferred)
Ideally degree-qualified with MRICS, MCIOB or equivalent (or working towards)
