About BuildQuants

The UK's AI-powered
quantity surveying practice.

BuildQuants combines chartered QS expertise with AI-driven measurement technology to deliver cost intelligence that is faster, more accurate, and more transparent than traditional practice. We exist to give every client — from first-time self-builders to national developers — the same quality of cost data that was previously reserved for Tier 1 contractors.

How We Work

Built on professional standards.

RICS-Regulated Practice

Every cost plan is prepared and signed off under the professional standards of the Royal Institution of Chartered Surveyors.

Accuracy-First Approach

We measure from drawings, not assumptions. NRM-compliant elemental breakdowns give you line-by-line cost visibility before a single brick is laid.

Client-Centred Delivery

From self-builders to commercial developers, we tailor our output to your decision-making needs — not the other way around.

Standards We Operate Under

Every output from BuildQuants is prepared in accordance with the following industry standards. We do not deviate from these — they are the foundation of our professional credibility.

Our Technology

AI-assisted measurement.
Human-verified accuracy.

BuildQuants has developed a proprietary AI measurement engine that reads construction drawings, extracts quantities, classifies building elements, and produces a structured elemental take-off in minutes rather than days.

But AI alone is not enough for cost-critical decisions. Every output from our engine is reviewed line-by-line by a chartered quantity surveyor who validates assumptions, applies professional judgement, flags risks, and signs off the final deliverable. The AI does the heavy lifting. The QS ensures the accuracy.

This hybrid approach means clients get the speed and consistency of technology with the accountability and expertise of a chartered professional. It is why we can deliver a full cost plan in 72 hours at a fraction of the cost of traditional QS practice, without compromising on quality or compliance.

01

Drawing Ingestion

SECONDS

Construction drawings are uploaded to our secure platform. The AI engine parses PDF and DWG formats, identifying drawing types, scales, and annotation layers automatically.

02

AI Quantity Extraction

MINUTES

The engine measures every element: walls, floors, roofs, openings, finishes, drainage, and external works. Quantities are classified to NRM elemental structure and cross-referenced against NHBC exposure requirements.

03

Chartered QS Review

PROFESSIONAL OVERSIGHT

A qualified quantity surveyor reviews the AI output, validates measurement assumptions, applies specification judgement, flags design risks, and confirms every rate against current market data.

04

Deliverable Sign-Off

CHARTERED ACCOUNTABILITY

The final cost plan is formatted to NRM structure, assumptions and exclusions are documented, and the report is signed off by an MRICS-qualified surveyor before delivery to the client.

The result: Clients receive a professionally formatted, chartered-approved cost plan in 72 hours, not weeks. Every number is measured. Every assumption is documented. Every report is signed off.
