01What it handles

Manage your loading and calculations quickly

From house calculation packs to towers and preliminary design, every load ready for your design and analysis.

Tributary areas, storey by storey

Every slab split into the area each column, beam and core wall carries, coloured to match the element it loads.

Use stress mapping for load distribution in masonry

A simple overview of the stress in each wall to aid understanding of structural behaviour: how load spreads under the lintels and what it puts on the storey below.

02How it works

From drawings to foundation loads in minutes

Auto build coming soon: instantly create your model from your PDF.

Step 1Model

Build the model from your drawings

Import the architect's plans and LoadTakedown picks out the walls and floors, then works out the tributary areas. Adjust anything by hand with snapping.

  • Multi-page PDF
  • One- and two-way spans
  • Beams and columns
An architect's floor plan becomes walls and floors, then coloured tributary areas, then a 3D house with the load at each wall base

Step 2Elevate

See the stress in every masonry panel

Add windows and doors, and watch the lintels pick up the load and the masonry spread it down to the base, leaf by leaf.

  • Openings and lintels
  • Stress in N/mm²
  • Cavity leaves
Masonry wall elevation with window and door openings and the stress spreading under the lintels

Step 3Check

Check every tributary area

Every floor and roof slope split into the area each wall, beam and column carries, coloured to match the element it loads. Change a span and it updates at once.

  • One- and two-way spans
  • Coloured by element
  • Load balance every run

Step 4Report

Export the calculation report

A PDF and Excel report with the marked-up plans, a load summary, the foundation schedule and every wall's working.

  • Lintel schedule

03What it does

Features

A structural planner, more than a column schedule: design and plan the building between its levels, from the first scheme to the final schedule.

LoadTakedown in 3D: an eleven-level tower pulled apart level by level, with each level's plan in the levels panel

Every level's plan on one shared grid, so each column can be followed from the roof to the foundations.

11 levels
5 × 4 grid
18 columns

Concept design

Set the strategy for the whole building, level by level

Stack the plans for every level and see how a decision on one floor lands on the floors below. Mark go and no-go zones for structure, then test the frame before the design is fixed.

  • Every level's plans on one grid
  • Go and no-go zones for structure
  • Clashes between levels shown straight away

Rationalisation

Column rationalisation tools to enable buildability

Each column gets a type on every level. Set the capacities, the storeys where a size may change and the utilisation you will accept, and fifty columns on plan become a handful of types.

  • Types and capacities by storey height
  • Steps only at the levels you allow
  • Out to Excel, Revit and IFC

Checking and validation of analysis models

Catch columns that typical FE models may understate

Complex buildings with transfer structures are often calculated incorrectly in FE models. A load takedown is a simple, independent way to check them, and catches these columns before they go on the schedule.

  • Load shared by tributary area, not stiffness
  • Every column compared with ETABS on plan
  • Differences near cores and transfers flagged

07Questions

Common questions

No. LoadTakedown runs in your normal web browser on any computer, Windows or Mac, with nothing to install. A desktop app that also works offline, with projects saved as files on your own machine, is on the way.

Tributary areas come from the walls, beams and floors in your model, then the dead and imposed loads you set are taken down storey by storey to the foundations. Every run checks that the load reaching the foundations balances the load applied, and the report shows each wall's working so it can be checked by hand. The engineer stays responsible for the design.

More on the method in the blog →

Yes. Import an IFC model from Revit, Tekla, ArchiCAD or any other BIM tool, and its walls, slabs, columns and beams come in at their modelled sizes, one level per storey. Pro exports the model back out as IFC with the loads, reactions and tributary areas attached, so the takedown fits into your BIM workflow.

How IFC import and export work →

Yes, from a house extension to a complex multi-storey frame. Use a drawing per level, set the storey heights, and model masonry walls, steel and concrete beams and columns, and one-way or two-way slabs.

You choose a region for each project. US projects use ASCE 7-22 live loads with ASD and LRFD gravity combinations, in psf, plf and lb. UK projects use BS EN 1990 and 1991-1-1 with the UK National Annex, and European projects the recommended values, in kN/m² and kN/m. Anywhere else you can enter your own loads and factors.

Signed in, your projects and the drawings you upload save to your LoadTakedown account as you work, so they follow you to any computer. They are stored securely and are not shared with other users. If you would rather keep a project on your own machine, save it as a file instead.

Every load is worked out the same way every time, straight from the model, so there are no hand-measured areas or broken formulas, and the load balance is checked on every run. Each wall's working is laid out to check by hand, on the plan and in 3D. When the architect moves a wall, change the model and every load updates in seconds instead of reworking the sheet.
