Quantity Surveyors in building.
A building QS works on the buildings people live, work, learn and get treated in: residential, commercial, education, health and mixed use. Usually on the main contractor side, running the packages and the subcontractors who deliver them.
The work.
Procuring packages, valuing the work each month, and managing subcontract accounts, variations and the final account. On design and build, it means managing the design as it develops and the cost of every change.
The main contractor QS sits between the client's account and dozens of subcontract accounts. The margin lives in the gap.
The contracts.
Most often JCT Design and Build, heavily amended by developer clients, with NEC on public sector frameworks. Subcontracts go out on the main contractor's own amended terms. Retentions, payment notices, and loss and expense are where the money is won and lost.
The clients.
Developers and investors on residential and commercial schemes. Public sector frameworks for schools, hospitals and council work. Housing associations. Main contractors from national to regional, and the subcontractors beneath them.
What a good building QS has usually done.
Taken a building through to final account on the main contractor side. Run subcontract accounts and closed them out. Handled design and build risk on amended JCT. Knows how payment notices work, and what happens when one is missed.
How careers move.
In. From a subcontractor or consultancy role. The main contractor seat is where the whole account comes together.
Through. From package QS to project QS to commercial manager, on a single scheme or across a region.
Out. Client side with a developer, into consultancy, or across to M&E, fit-out or data centres.
Freelance QS work in building.
Final accounts, subcontract account closure and disputes on completed schemes. That is Delivery work.

Do you have building Quantity Surveyor jobs?
Yes, Permanent and Contract, with main contractors, subcontractors and client side. A Career Insight Call is where to start.
What is the difference between a building QS and an infrastructure QS?
Building mostly runs on JCT for private clients. Infrastructure mostly runs on NEC for public and regulated ones. The commercial skill is the same. The contract, the client and the pace are not.
Can a building QS move into infrastructure?
Yes, with the right first role. The contract is the main thing to learn. A building QS who already knows NEC is halfway there.
Main contractor or consultancy?
Main contractor if you want to own the account and the margin. Consultancy if you want breadth across clients and projects. Both are good careers. Moving between them is easier early than late.
Is there freelance building QS work?
Yes. Final accounts and subcontract closure on completed schemes are defined pieces of work, which suits a freelance QS.
