Quantity Surveyor

Quantity surveyors (QS) manage the financial and contractual aspects of construction projects across all sectors — residential, commercial, infrastructure, and civil engineering. Core responsibilities include producing bills of quantities and cost plans at early design stage, tendering work packages to subcontractors and evaluating returns, negotiating and administering construction contracts (JCT, NEC, and others), valuing work in progress and certifying interim payments, managing change control and variations, advising on procurement strategy, and producing final accounts at project completion. QS professionals work on both the client side (employer's QS or cost consultant) and the contractor side (main contractor or subcontractor commercial management).

The Royal Institution of Chartered Surveyors (RICS) governs professional standards through the MRICS qualification. The route is typically a RICS-accredited BSc in Quantity Surveying followed by the Assessment of Professional Competence (APC) — a structured post-graduate competency assessment against defined RICS competencies, typically taking 2–3 years of structured training in an employer's APC programme. The Level 6 Quantity Surveying Professional degree apprenticeship (IfATE) provides an employer-funded route combining work and study. Progression leads to senior QS, commercial manager, project director, or partnership in a cost consultancy. Chartered QS professionals work across public sector, developer, contractor, and consultancy environments.

Every construction project — from a single house extension to a major infrastructure scheme — requires cost management and contractual oversight. The financial risk in construction is substantial; without professional QS management, contractors and clients routinely face cost overruns, contractual disputes, and financial exposure. The RICS APC qualification and ongoing CPD requirements create a professional framework that is difficult to replicate without formal training and supervised experience, protecting established practitioners.

Quantity surveying involves complex judgement about what work is in scope, what constitutes a valid claim, and how to interpret ambiguous contract terms in specific project contexts — this is fundamentally different from quantification work that can be automated. BIM (Building Information Modelling) tools have automated some repetitive taking-off tasks, but the commercial, contractual, and negotiating skills at the heart of QS practice are highly people-dependent. The profession is internationally portable through RICS global recognition, and demand is consistent across both public infrastructure spending and private sector development.

Morning: attend a monthly project cost review meeting with the project director and client — present an updated cost report for a commercial fit-out scheme, explain variances, flag a pending change on M&E services, and agree a revised forecast final cost. Back at the desk: value a subcontractor's interim application for payment, check measured quantities against drawings, assess the contractual basis for a disputed variation, and prepare a recommendation for certification. Afternoon: draft a tender document for the next work package, review incoming tender returns from three subcontractors, and produce a tender analysis for the project manager.
