Everything you need for load takedowns
From PDF import to foundation loads, all in one tool.
Import a multi-page PDF and have tributary areas in 5 minutes
Set scale, enter levels, trace walls and floors with snapping. Tributary regions generate automatically on the drawing.
See exactly where loads resolve, visually on the drawing
Tributary areas, load paths, and support reactions displayed directly on the plans. Spot missing supports or geometry issues at a glance.
Visualise your structure in 3D with results overlaid
Switch to the 3D view to see your full building model with walls, floors, and load results rendered together. Select any element for detailed cross-section analysis.
Built for structural engineers
From plan markup to foundation loads in minutes, not hours.
2D Plan Editor
Draw directly on your PDF plans
Import multi-page architectural PDFs, set scale and levels, then trace walls and floors with snapping. Tributary areas and load paths update live as you draw, so you can spot issues while you work.
Wall Cross Section
Trace every load from roof to foundation
See exactly how loads accumulate through each level. UDLs from tributary areas, self-weight, and distributed line loads are all shown on an interactive wall cross-section diagram with running totals at each storey.
Detailed Results
Auditable calculation output, ready for reports
Every floor resolves to a detailed results table showing supported line loads and point loads by wall and beam. Tributary region diagrams and load diagrams sit alongside the numbers so you can verify at a glance.

Frequently asked questions
Yes. You can import PDFs, draw walls and floors, calculate tributary areas, and review load paths, all for free with no account required. PDF export of calculation reports is £9/month.
No. LoadTakedown runs entirely in your browser. There's nothing to download or install, just open the app and start working.
Your projects stay local in your browser using IndexedDB storage. Your PDFs and calculations are never uploaded to our servers unless you explicitly choose to save to the cloud.
LoadTakedown works with multi-page PDF files, the format most architects and engineers share drawings in. Import your PDF, set a scale, and start marking up structural elements.
LoadTakedown calculates tributary areas geometrically from the walls and floors you draw, then applies the dead and live loads you specify per zone. The results are as accurate as your inputs and designed for early-stage feasibility and scheme design.
Yes. You can import a different PDF page per level, stack levels with defined storey heights, and LoadTakedown will accumulate loads down through the structure to give you foundation-level totals.
The exported PDF includes your marked-up floor plans with walls, floors, and tributary regions overlaid, plus a structured calculation report showing loads per wall at each level. It's designed to be a clear, auditable document you can include in your project records.
Spreadsheets require you to manually measure tributary areas from drawings and type them in, which is error-prone and slow. LoadTakedown lets you draw directly on the PDF and calculates tributary areas automatically, so you get results in minutes instead of hours.
