For architecture & interior portals

From first inquiry to final handover.

Atelier OS digitises the full eight-phase portal lifecycle — drawings, approvals, RFIs, BOQ and snagging — in one composed, considered workspace.

The eight phases

A standardised lifecycle. Every project. Every portal.

No more spreadsheet stitching. From the first client email to the as-built handover pack, each phase has a defined entry gate, a deliverable, and a sign-off.

Capabilities

Designed for portal rigor.

Replace the patchwork of email, PDF revisions and WhatsApp threads with one auditable system of record.

Versioned drawing control

Strict supersede workflow blocks issuing un-approved drawings. Every revision tracked, every issue logged.

Client portal with sign-off

Concept boards, renders and DD packages — approved with a timestamp, change-requests routed back to the portal.

Live RFI & snagging logs

Site queries closed on 48h SLA. Photo-tagged snags clear before handover. No paper, no PDF chains.

BOQ tied to budget

Quantities and rates feed live cost reconciliation. Change requests carry mandatory cost-and-time impact.

“We closed our last project with zero drawing-version disputes. The handover pack wrote itself.”
Léa Marchetti · Lead Architect, Portal Cantillon
