View, compress, coordinate, validate, check and analyse BIM models — using IFC, the Open BIM model format of buildingSMART. Each task has its own fast, native Windows app: open an IFC file and get the answer on the model.
A fast, clean viewer for IFC models: open one file or several, filter what you see, cut through the building and inspect any element.
See what it does →Every screenshot is the real app at work — most of them on the AC20-Institute sample building. Each tool lists the sample files that go with it.
IFC Viewer · 1 tool
A fast, clean viewer for IFC models: open one file or several, filter what you see, cut through the building and inspect any element.
Opens IFC2X3 and IFC4 files with real materials and a ground grid. Click any element to read its full record.
Shown with AC20-Institute
IFC Compressor · 1 tool
Shrinks IFC files without changing what they describe — and shows the compressed geometry right beside the log that produced it.
Rounds coordinates, merges duplicate entities, removes data nothing references and renumbers the file. The result opens in the viewer the moment the run finishes.

Coordinate · schedule · review · 4 tools
Four coordination tools in one window: a viewer with chat and takeoff, clash detection, a 5D construction simulator and a BCF issue viewer.
Ask questions about the model in plain words, and browse every element and property in a takeoff table that drives the 3D view.
Shown with AC20-Institute
Finds elements that overlap by more than a chosen share of their volume, grouped so the real problems come first.
Shown with AC20-Institute
Links a construction schedule to the model and plays the build forward, with cost and earned value alongside.
Shown with AC20-Institute
Reads and writes BCF 2.1 issue files, so issues travel between Zentro and other BIM tools.

IDS authoring and validation · 2 tools
Write buildingSMART IDS 1.0 requirement files, then check models against them — with the answer painted on the building.
A form for writing IDS files, with the generated XML beside it as you type.
Shown with the Architectural fire safety IDS
Checks a model against one or more IDS files and colours the result in 3D.

Model QA and facility data · 6 tools
Six tools for checking a model and connecting it to the data that runs the building.
Eight checks for the problems that break downstream tools, grouped by severity and painted on the model.
Shown with AC20-Institute
Brings sensor readings onto the model, so you can see where each value comes from.
Shown with AC20-Institute
Follows the structure from top to bottom and flags where the load path breaks.
Shown with AC20-Institute
Maps IFC classes to cost codes and rolls quantities up into a bill of quantities.
Shown with AC20-Institute
Reviews several discipline models together, aligned on shared levels.
Shown with AC20-Institute
Links an asset register to the model and shows status, maintenance and criticality in 3D.

Fire, energy, carbon and cost · 5 tools
Five checkers and calculators for safety, envelope performance, embodied carbon and cost.
Checks compartment sizes, escape distances and fire ratings against an occupancy-based ruleset.
Shown with AC20-Institute
Finds the envelope, checks U-values against limits and lists junctions that can bridge.
Shown with Ifc4 SampleHouse
Links a carbon register to the model and shows embodied carbon per element and in total.
Shown with AC20-FZK-Haus
The same register workflow for cost: link estimate lines to the model and see where the money goes.
Shown with AC20-FZK-Haus
Checks doors, ramps, corridors and WCs against accessibility dimensions.

Quantities, solar and versions · 5 tools
Five tools for costing, solar potential, space programs, version comparison and setting-out.
Prices the model from a unit-cost table using the quantities authored in the file.
Shown with AC20-Institute
Finds roof areas suitable for solar panels and estimates the yearly yield.
Shown with AC20-Institute
Compares a room program with the spaces in the model.
Shown with AC20-Institute
Shows what changed between two versions of a model, side by side with synchronised cameras.
Shown with AC20-Institute and its compressed copy — no geometric differences
Checks that elements sit on the structural grid and on their storey levels.

Building performance and egress · 6 tools
Six analysis tools for occupancy, escape routes, daylight, acoustics, MEP access and reinforcement.
Calculates occupant load per space from its use and area, and flags overloaded exits.
Shown with AC20-Institute
Builds the route graph of spaces, doors and stairs and finds every space's way out.
Shown with AC20-Institute
Calculates direct sun hours for each space on a chosen date.
Shown with AC20-Institute
Checks that walls and slabs between spaces carry the sound ratings they need.
Shown with AC20-Institute
Checks that MEP equipment keeps clear space in front and above for access.
Shown with the MEP sample model
Checks reinforcing bars, meshes and tendons for cover, spacing and diameter.
