What this service covers

QS services covering Bills of Quantities (BOQ), valuations, variations, claims, and final accounts.

Quantity Surveyor (QS) services follow the Commonwealth tradition of cost management — distinct from US-style estimating in standards (NRM2 or SMM7 versus CSI), deliverable format (Bill of Quantities versus estimate workbook), and engagement model (often owner-side cost manager versus contractor-side estimator).

Vortex QS work supports international contractors bidding into Commonwealth markets, US owners with overseas projects, and developers who want third-party quantity validation independent of their contractor.

How we work

Every quantity surveyor services engagement starts with a free scope review — typically within 4 business hours of receiving your documents. We confirm the deliverable scope, turnaround, and fee before any work starts. Estimates and takeoffs are produced by US-based senior estimators with a minimum of seven years on the discipline in question, then reviewed by a second estimator before delivery.

Deliverables ship in your preferred format — PDF, Excel, your estimating software’s native file, or a custom client template. Bid-day clarifications during your bid submission window are handled in under an hour.

Why outsource this work

Outsourced specialty estimating gives contractors access to senior trade-specific capacity without the fixed cost of a full-time hire. The economics are simple: a senior in-house estimator costs $90K-$150K/year fully loaded; outsourced per-project work is paid as it’s used. For shops with irregular bid volume or specialty trades they bid only occasionally, the math heavily favors outsourcing.

Frequently Asked Questions

What's the difference between US estimator and quantity surveyor?
US estimating is structured around CSI MasterFormat or UniFormat. Commonwealth-tradition quantity surveying uses standard methods of measurement (NRM2, SMM7) and produces a formal Bill of Quantities. We do both — useful for US contractors bidding international work or international firms working in the US.
