Datum, your compliance checker
Datum is our compliance checker, a tool that tests a design against the building bylaws while the design can still change, from inside Revit or AutoCAD or from a model you upload.
Try it for freeCompliance is usually confirmed at the end, once the drawings are finished and a consultant or the sanctioning authority finds what does not pass.
A setback a hundred and fifty millimetres short or an area read the wrong way sends a scheme back through the studio weeks after the decisions that caused it.
Datum runs where your team already works, inside Revit or AutoCAD, or on an IFC model or a DXF drawing uploaded to the web app. All four read the design the same way, so a rule is tested the day the decision is made rather than the month the drawings go out.
Every result names the clause it comes from, down to the page it was copied from, and shows the measured value against the limit, so a failure can be argued or fixed instead of taken on trust.
A failure says how much to change in the unit of the rule, and the FSI card shows what you have used against what you are allowed and the floor area you still have left to build.
In Revit the margins, the FSI and the height move as you model, so you watch a limit coming rather than meeting it once the drawings are done.
Where the design does not carry a fact a rule needs, such as the Development Plan width of the road, Datum says it cannot verify that clause and asks you one question rather than assuming a pass.
The issues come back where the design is. Revit colours the failing elements in a view of its own with a list docked beside it, AutoCAD clouds them on a layer of their own, and the web app gives you a printable report to send on.
