Title Block
Contains project name, drawing number, scale, revision history, and preparer information so every party can identify and correlate the sheet.
An approved drawing creates a single accepted reference that reduces rework, clarifies scope, and supports contractual obligations. It documents sign-off, preserves version control, and provides an audit trail for change orders and claims.
Several roles participate in producing and approving drawings; responsibilities differ by organization and project phase.
Clear role assignment and an approval matrix reduce ambiguity during approvals and help enforce contractual acceptance criteria.
| Field | Configuration |
|---|---|
| Signature Placement | Place signature and date fields in the approval block only |
| Reviewer Order | Enforce sequential reviewer order for technical then commercial approval |
| Authentication | Use email + SMS code or stronger where required |

Contains project name, drawing number, scale, revision history, and preparer information so every party can identify and correlate the sheet.
Records all revision entries with dates and brief descriptions to show what changed between versions for claims and procurement.
Designates required approvers with signature lines, titles, organizations, and dates so responsibility and acceptance are explicit and auditable.
Provides concise scope, exclusions, critical dimensions, and material callouts that contractors and fabricators rely on to execute work correctly.
Lists related specifications, standards, and referenced drawings so reviewers can cross-check requirements without guessing context.
Includes professional stamps or seals where required by licensure or regulation to validate technical approval for construction use.
Provide the signed drawing as a flattened, high-resolution PDF and retain the original native file (DWG, RVT) in source archives.
Use a standard like Project_DrawingNo_Rev_Date.pdf so teams can identify the approved revision instantly and avoid version mixups.
Include revision history and approver metadata in the file properties for automated indexing and search.
Confirm the PDF adheres to ISO standards and that drawings render correctly on common viewers used by contractors and permit authorities.
Use a platform that supports secure eSignatures, audit trails, and common integrations to avoid manual handoffs.
Ensure the platform can capture signer identity, timestamps, and an immutable audit log to meet internal and regulatory recordkeeping needs.
