Job description

Quantity Surveyor - Major Project (NEC, Site-Based)

Location: Cardiff (Site-Based)

Salary: £65,000-£75,000

Job Type: Permanent or Freelance (£350-£400 per day)

A well-established contractor is looking to appoint a Quantity Surveyor to support delivery on a major live project in Cardiff.

This is a site-based role on a large, fast-moving scheme, working as part of the delivery team alongside the principal contractor and key project stakeholders to maintain commercial performance and control.

The project includes elements of building services and complex packages, but the role is focused on overall commercial management and coordination, rather than technical M&E design or engineering detail.

The Role

You’ll be embedded within the delivery team, taking responsibility for day-to-day commercial management across key packages on a major live scheme.

This is a hands‑on position where you’ll need to stay close to the project, maintain control of costs, and support the team in managing change effectively across multiple work packages.

Key responsibilities:

• Managing subcontractor accounts, valuations and payments
• Leading on variations, change control and NEC compensation events
• Producing cost reports, CVRs and forecasts
• Supporting procurement and package management across key packages
• Working closely with Project Managers to maintain commercial control
• Identifying risks and resolving commercial issues proactively
• Managing contractual notices and ensuring NEC compliance

You’ll have:

• Experience as a QS on construction or infrastructure projects within a live project environment
• Strong working knowledge of NEC contracts (essential)
• Experience managing subcontractor packages, valuations and variations
• Ability to operate independently in a site-based role
• A proactive, delivery‑focused approach

This role suits someone who is comfortable being close to the build and actively involved in delivery, it's not suited to purely office‑based or consultancy‑led commercial roles.

Exposure to M&E or building services packages is helpful, but not essential.

What's on Offer

• £65,000-£75,000 salary (DOE)
• Or £350/day freelance option
• Long‑term project with potential for further work
• Opportunity to play a key role on a major live scheme
• Growing business with a strong forward pipeline

Why This Role

• Site-based role with real involvement in delivery
• Work closely with an experienced project team on a major scheme
• Clear opportunity to take ownership and make an impact
• Long‑term opportunity within a busy and expanding contractor
