Security

  • Rebuilding the bill-of-quantities semantic-search index now enforces the same access rules as the rest of the module. You can re-index a single bill or a single project only when you can already open it, and a full re-index of every project is restricted to administrators. Previously any account permitted to edit a bill could rebuild - or, with the purge option, wipe - another tenant's search index by supplying its project or bill id.

Fixed

  • The bill-of-quantities resource summary now converts foreign-currency resources into the project's base currency before adding them up, so the per-type subtotals and the grand total no longer blend different currencies. A resource priced in a currency that has no configured exchange rate is kept in its own units rather than dropped, matching how the cost breakdown already behaves.
  • Editing a bill of quantities, a markup line or a takeoff measurement now merges your change into the record's saved metadata instead of replacing the whole block, so values the server stamps in the background (for example takeoff-run, comparison and verdict markers) are no longer lost when you save an unrelated edit.
  • The safety total-recordable-incident-rate (TRIR) indicator and its drill-down now read the safety incident records correctly. The metric previously always reported zero and the drill-down was always empty.
  • A bill-of-quantities position priced in a foreign currency whose exchange rate is present but unreadable is now kept in its own units instead of being converted one-to-one, matching the resource-level behaviour.
  • The federated BIM viewer no longer throws when the browser or device has no WebGL2 support; it now fails softly so the rest of the page keeps working.
  • Currency amounts in the cost-breakdown and resource-summary panels render reliably from the server's exact values, avoiding occasional malformed totals.
  • Confirming many detected takeoff measurements at once now writes them in a single database operation instead of one round-trip per row.
  • Installing a CAD or BIM converter no longer fails with a "request timed out" error when the download is slow to start. The install always runs in the background and the converters panel updates when it finishes, even if the initial request is dropped by a busy backend or a flaky connection.
