From drawings to cost plan.
Three steps. AI does the heavy lifting. A chartered QS ensures every number is right. You get a professionally formatted cost plan in 72 hours, not weeks.
Upload Your Drawings
Submit your construction drawings in PDF or DWG format through our secure portal. Architectural, structural, M&E, and civil packages all accepted. Your project is live within minutes.
AI Measures Everything
Our AI engine scans every drawing, extracts quantities, classifies elements, and produces a full elemental take-off in minutes rather than days. Every measurement is structured to NRM and cross-referenced against NHBC exposure requirements.
Chartered QS Reviews & Signs Off
A qualified quantity surveyor reviews every line of the AI output, validates assumptions, flags risks, applies professional judgement, and signs off the final cost plan. No report leaves without human accountability.
Our core services.
Six core disciplines delivered to the same exacting standard — whether you need a single cost plan or a full commercial management service across a multi-site programme.
Quantity Take-Off & Cost Estimating
Full elemental cost plans from construction drawings, broken down to labour, materials, and subcontract level. Every line measured, unit-rated, and benchmarked against BCIS.
Life Cycle Cost Planning
Model the full cost of owning and maintaining a building over 30 or 60 years using the CROME framework. All future costs discounted to NPV using HM Treasury Green Book rates.
Build Programmes
Logic-sequenced construction programmes tied directly to quantities measured. Critical path identified, long-lead procurement flagged, parallel working opportunities maximised.
Option Appraisal & Value Engineering
Whole-life cost comparison across specifications, procurement routes, and design options. Capital cost, maintenance, renewal, and energy — decisions made on evidence, not assumption.
Procurement & Tender Advisory
Contract strategy advice — NEC4, JCT 2016, framework or two-stage. Tender structuring, evaluation criteria, risk allocation, and PCR 2015 compliance for public sector clients.
Maintenance Strategy & SFG20
All maintenance tasks mapped to SFG20 codes with planned preventative maintenance frequencies and annualised cost forecasts — a compliant, costed maintenance plan from day one.
Who we work with.
Self-Builders
Building your own home is one of the most significant financial commitments you'll make. We give self-builders access to the same level of cost control and professional oversight that large developers take for granted.
Homeowners
Planning a significant extension, loft conversion, or whole-house renovation? We provide detailed cost plans and contractor-ready documentation so you know exactly what your project should cost before you appoint anyone.
Construction Contractors
Whether you're pricing a tender or managing costs on site, we provide robust take-offs and elemental cost plans that stand up to scrutiny — in the format you already use, at the pace the industry demands.
Architects
Cost checks, elemental benchmarking, and value engineering advice at every RIBA stage — keeping schemes viable without compromising design intent. Early cost advice prevents the costly redesigns that happen when budget reality hits late.
Developers
From initial feasibility through to tender and post-contract cost control, we provide the commercial discipline that makes development projects stack up. We understand development appraisals, phased programmes, and planning risk.
Commercial Professionals
For asset managers, facilities directors, investors, and commercial occupiers — life cycle cost modelling, procurement strategy, and maintenance planning that protects asset value and controls long-term expenditure.
Industry standards, not shortcuts.
Every cost plan we produce is measured and structured to the highest professional standards — ensuring compliance and commercial rigour throughout.
BuildQuants operates under RICS regulation, ensuring every deliverable meets the profession's highest standards of competence and professional ethics. Every report is signed off by an MRICS-qualified quantity surveyor.
New Rules of Measurement for order of cost estimating and building maintenance works — our primary measurement standard.
Technical requirements and standards for durability, exposure classification, and timber specification compliance.
Green Book methodology for DCF/NPV life cycle modelling. 3.5% real discount rate for public sector clients as standard.
Concrete specification and exposure classification — XC, XF, XS, and XD classes applied with appropriate cost uplifts.
Maintenance task scheduling and labour costing — every PPM task coded, resourced, and annualised.
Timber preservation and Use Class requirements — UC1 through UC4 assigned and costed for every timber element.
The difference is clarity.
Traditional QS consultancy is expensive, slow, and difficult to access. BuildQuants combines AI-powered measurement with chartered professional oversight to deliver the same quality at a fraction of the cost and turnaround time. Technology does the heavy lifting. Expertise ensures the accuracy.
AI Speed, Human Judgement
Our AI measures drawings in minutes, not days. A chartered QS then reviews every line, applying 20 years of professional judgement before anything is delivered.
72-Hour Turnaround
Traditional QS firms take weeks. Our AI-powered workflow delivers chartered-approved cost plans in as little as 72 hours for standard service levels.
Chartered Sign-Off, Every Time
No report leaves BuildQuants without review and sign-off by an MRICS-qualified quantity surveyor. AI measures. Humans verify. Clients trust.
No Hidden Assumptions
Every assumption, exclusion, and risk is documented explicitly. Clients know exactly what is and isn't included, every time.
What our clients say.
BuildQuants delivered a detailed cost plan within 72 hours that was more thorough than reports we've waited weeks for from traditional QS firms. The NRM-structured format made it immediately usable for our funder.
The level of detail in the elemental breakdown was exceptional. Every assumption was documented, every exclusion flagged. It gave us complete confidence in the budget before we went to tender.
We've used BuildQuants on three projects now. The consistency of output and speed of turnaround is remarkable. The value engineering recommendations alone saved us over £40k on our last scheme.
