Drawings
The drawing register, from receipt through review to superseded — with transmittals tracked and markups held against the right revision.
Overview
Revisions, transmittals and markup
Drawings maintains full revision control across the project, tracks every transmittal in and out, and holds markups against the specific revision they were made on.
The lifecycle is explicit: received, under review, approved for construction, superseded. Anyone can see which revision is current for a given area and what changed between issues, on site as well as in the office.
Building to a superseded drawing is one of the most expensive avoidable errors in construction, and it is almost always a communication failure rather than a competence failure. When the current revision is unambiguous and available on the device in someone’s hand, that category of rework largely disappears.

How it works
The drawing lifecycle
Received and registered
Incoming drawings are logged with revision, discipline, area and issue date.
Reviewed and commented
Markups attach to the revision they were made against, not to a folder, so comments never drift onto the wrong issue.
Issued for construction
Transmittals record who received which revision and when.
Superseded, not deleted
Old revisions remain accessible and clearly marked, which matters when reconstructing what was in force on a given date.
Why it matters
On a live project
No building to superseded drawings
The current revision is unambiguous, on site as well as in the office.
Transmittals evidenced
Issue and receipt are recorded, which settles a surprising number of arguments.
Comments stay attached
Markups belong to the revision they were made against, not to a folder somewhere.
Use cases
Where it is used
Site issue control
Field teams open the current revision on a tablet rather than working from a printed set of uncertain age.
Design change tracking
What changed between revisions, and the cost and programme consequence of the change.
Coordination
Cross-discipline markups held in one place rather than exchanged as annotated PDFs by email.
Questions
Frequently asked about Drawings
Yes. Drawings can be cached on a device and sync when connectivity returns, which matters in basements and remote sites.
Integration with design tools is scoped during implementation as part of our custom integration work.
Yes, revisions can be compared so the change between issues is visible rather than inferred.
Issue rights are role-based, and every transmittal is recorded in the audit log.
