Measure Plans Instantly.
Price Accurately.
Upload any PDF floor plan, calibrate the scale, and draw polygons to measure areas and lengths. Let AI auto-detect rooms, walls and dimensions — then generate a fully priced BoQ in one click.
Powerful takeoff tools, zero installation
Everything you need to measure floor plans and produce quantities — right in your browser
Draw & Measure
Draw polygons for area takeoff, polylines for linear measurements, and count markers for items. Live m² and linear metre totals update as you draw.
AI Auto-Detect
One click triggers AI Vision to scan the entire page. Rooms, walls, doors and dimensions are detected automatically with coordinate-based polygons you can confirm or adjust.
Scale Calibration
Click any dimension annotation on the plan, enter the real-world length, and the scale is set. All measurements inherit that precision across every page.
How takeoff works in MyQS
Three steps from PDF to priced bill of quantities
Upload your PDF
Drag and drop any PDF floor plan. Multi-page documents are supported — each page appears as a thumbnail you can switch between.
Set scale & measure
Calibrate the scale from a known dimension, then draw polygons and lines to measure areas and lengths. AI auto-detect can do the heavy lifting for you.
Generate priced BoQ
One click consolidates all measurements into a de-duplicated bill of quantities with UK rates, ready to download as a professional PDF.
Built for real construction workflows
Work sections & scope trees
Organise measurements into NRM1 work sections with a 3-level scope tree. Group items by trade, rename categories, and keep your takeoff structured from the start.
Cross-reference AI vs manual
Fuzzy label matching and centroid distance algorithms compare AI detections against your manual measurements. See matched, missing and extra items at a glance.
Multi-page thumbnail sidebar
Every page from every uploaded document appears as a thumbnail with measurement badges. Switch between pages instantly and see totals per page in the status bar.
Copy measurements between pages
Reuse measurements across drawings with one click. When multiple sheets show the same floor plan with different overlays, copy your takeoff instead of redrawing it.
Everything you need for digital takeoff
Frequently asked questions
Construction takeoff software is a digital tool that lets you measure quantities directly from floor plans and drawings. Instead of printing plans and using a scale ruler, you upload a PDF, calibrate the scale, and draw polygons or lines to calculate areas, lengths and counts. MyQS combines manual polygon tools with AI auto-detection to speed up the process — rooms, walls and dimensions are identified automatically so you can focus on reviewing rather than drawing every shape by hand.
Yes. MyQS accepts PDF floor plans of any size. Upload your drawing, set the scale using any known dimension annotation on the plan, then measure areas and lengths by drawing polygons and polylines directly on the page. The AI auto-detection feature can also scan the entire page and identify rooms, walls and openings automatically, returning coordinate-based polygons you can confirm or adjust.
AI takeoff in MyQS is very accurate when the scale is calibrated correctly. The system uses PDF vector extraction to read exact geometry from the drawing file, then cross-references AI detections against manual measurements using fuzzy label matching and centroid distance. Scale calibration maps a known real-world dimension to the PDF coordinate system, so all subsequent measurements inherit that precision. Users typically see accuracy within 1-2% of manual QS measurements.
MyQS offers a free tier that includes basic takeoff access with up to 3 MB file uploads and 3-page floor plans. You can draw polygons, set scale, and generate measurements at no cost. The Pro plan at £69/month unlocks the full interactive takeoff tool with AI auto-detection, multi-page support, up to 50 MB uploads, and priced BoQ generation. No software installation is needed — it runs entirely in your browser.
