Your FAQs Answered
1. What does a quantity surveyor do in London?
A quantity surveyor in London helps manage the financial and contractual side of your construction project. This includes cost planning, estimating, preparing Bills of Quantities, managing valuations, handling variations, forecasting costs, and supporting contract administration. The goal is to ensure your project remains on budget and commercially protected from start to finish.
2. Why should I hire a quantity surveyor at the early stages of a project?
Hiring a quantity surveyor early allows you to set a realistic budget, improve design efficiency, and avoid unexpected costs later. Early-stage services such as feasibility studies, benchmarking, and elemental cost planning help you make informed decisions before committing to construction.
3. Do you only provide quantity surveying services in London?
No. iQuantity Consulting Ltd is based in London, but we support construction projects across the UK. Whether you need cost estimation, tender support, or post-contract cost management, our team works nationwide.
4. What types of projects do you specialise in?
We support a wide range of UK construction projects, including residential developments, commercial offices, retail spaces, education buildings, healthcare facilities, fit-outs, refurbishments, and mixed-use schemes. Our experience covers both public and private sectors.
5. How accurate are your cost estimations?
Our cost estimation London service is built on real market data, digital measurement tools such as CostX, and RICS-compliant processes. This ensures that your estimates are realistic, transparent, and aligned with current construction conditions.
6. What procurement routes can you advise on?
We provide guidance on traditional, design & build, two-stage tendering, framework agreements, and negotiated contracts. We help you choose the right procurement route based on cost, programme, risk, and project complexity.
7. Can you help with tender documentation and contractor selection?
Yes. We prepare tender packs, Bills of Quantities, Schedules of Works, and analysis reports. We also review contractor bids, identify risks, and help you select the most suitable contractor for your project.
8. What is included in your post-contract services?
Our post-contract services include valuations, interim payments, cost reporting, change control, variation assessments, contract administration (JCT/NEC), forecasting, and final account preparation. These services ensure your project stays commercially controlled throughout construction.
9. What is the difference between a quantity surveyor and a cost consultant?
Both roles focus on costs, but a cost consultant looks more at the strategic financial planning of a project, while a quantity surveyor handles both strategy and day-to-day commercial management. At iQuantity Consulting Ltd, we provide both services, offering end-to-end cost and contract support.
10. Are your reports RICS-compliant?
Yes. All our processes and reporting formats follow RICS standards, ensuring high-quality, professional, and fully compliant documentation for your project.
11. Can you act as Employer’s Agent for design & build projects?
Absolutely. We act as Employer’s Agent to manage contract execution, monitor programme, cost and quality, lead site meetings, and oversee practical completion and handover. This provides structured oversight and protects your commercial interests.
12. How do I get started with your quantity surveying services?
It’s simple. Contact us with your project details, and we’ll arrange a discussion to understand your scope, objectives, and timeline. From there, we provide tailored advice and propose the best service approach for your needs.
