Practice

USD 490.00 a seat / year

or USD 99.00 a seat monthly. A seat is each Engineer and Reviewer in the workspace; Viewers are free.

✅ Building-Pass access on every building, unlimited
✅ Keep a portfolio — describe each structure once
✅ Re-run any study when a building or an engine version changes
✅ Reports you issue while subscribed stay yours to download

A building bought outright is USD 149.00, so one seat pays from the 4th building of a year, and three seats from the 10th. Below that, buying passes is the better deal — and it stays available.

Start a Practice plan

There is no free trial, because the free tier is the trial. You can model your actual building and run all three studies without paying or committing to anything — real inputs, real engine, every verdict and all the working on screen. A trial that could also issue documents would just be a free month of the whole product; one that could not would show you nothing this does not already show you. So we skipped the countdown and left the door open.

A Building Pass covers one structure. Payments are processed securely by Paddle, our Merchant of Record, who handles invoicing and applicable taxes. See our Terms and Refund policy.
