Are you an Assistant Quantity Surveyor looking to build your career on a major, technically complex construction project?
My client is an established design, construction and engineering contractor delivering specialist projects across the data, defence and energy sectors.
They are looking for an Assistant Quantity Surveyor to join their commercial team, initially based on a major data centre development in Hayes.
This is a substantial project comprising 18 data halls, delivering approximately 24MW of usable IT power, together with HV and MV energy infrastructure, backup power generation and associated site infrastructure.
Working alongside experienced commercial and project teams, you'll get involved across the commercial lifecycle of the project while developing towards independently managing your own packages and commercial activities.
You'll support cost reporting and forecasting, valuations, subcontract procurement and accounts, variations, change management and final accounts, while working closely with the wider project team, subcontractors, consultants and suppliers.
It's a good opportunity if you've already started your career in Quantity Surveying and now want greater responsibility, exposure to a major project and the chance to develop within the growing data centre sector.
You don't need to know everything already. This is an Assistant QS position, and there is plenty of scope to develop your commercial experience while working on a complex live project.

If you're an Assistant Quantity Surveyor looking for your next step and interested in gaining experience within data centre construction, I'd love to hear from you.
