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.
