Formal transmittal of drawings from designer / consultant / contractor to recipient. Establishes contractual sequence + dates for issued-for-review, issued-for-tender, issued-for-construction.
Transmittal #2026-145, 12-May-2026. From: Arch Consultant. To: Main Contractor. Drawings: ARCH-FL-01 to ARCH-FL-08 (8 nos, Rev 2, GFC), A1 size, 2 copies each. Acknowledged by: Site Engineer, 13-May-2026.
A typical construction project issues 500-5,000 drawings across architectural, structural, MEP, plumbing, fire-safety, finishes, and external works disciplines. Each drawing has multiple revisions through the design cycle. The Drawing Transmittal Note is the formal handover record — issued whenever a new or revised drawing leaves the designer's office for the PMC, contractor, or client.
Without transmittal records, projects descend into 'who-has-what-version' chaos. Site teams build to outdated drawings; rework cost runs into lakhs. The transmittal note creates a legal paper trail: who issued what drawing, when, to whom, with what revision number. When defects emerge years later, the transmittal log identifies which revision was current at the time of construction.
Per-issue workflow: 1. Designer prepares drawing revision (e.g., R02 of structural slab plan for Level 3) 2. Drawing Transmittal Note generated — lists: drawing number, revision, date issued, distribution list (PMC + main contractor + sub-contractors + client), purpose (For Information / For Comment / For Construction / GFC) 3. Receivers sign acknowledgment of receipt 4. Each receiver checks against their drawing register; supersedes prior revision 5. Old revisions stamped 'SUPERSEDED' to prevent accidental use
Critical control: GFC (Good for Construction) status must be explicit on the transmittal — only GFC drawings are construction-issue. Non-GFC drawings issued 'For Information' or 'For Comment' cannot be used to build.
1. No formal transmittal — designer emails PDF directly to contractor; no acknowledgment; no register update. Site builds to wrong revision when newer one was issued informally.
2. Distribution gaps — sub-contractor not on the transmittal list never receives the revised drawing; continues using old version.
3. 'For Information' confused with 'For Construction' — without GFC marking, the transmittal note's purpose field is the only differentiator. Sites that ignore this distinction build to information-only drawings.
4. No revision tracking — multiple drawings transmitted with same revision number; designer loses track.
5. Hard-copy vs digital mismatch — site holds older hard-copy than current digital. The transmittal should explicitly state which is the controlling version (typically digital with GFC stamp).
6. Lost acknowledgment — when contractor disputes 'we never received that drawing', the transmittal acknowledgment signature is the PMC's defence.
Companion PMC formats: - Design Review Register (PMC-DES-REG-001) — design review tracking - GFC Submission Tracker (PMC-DES-LOG-002) — formal GFC release log - Clash Detection Report (PMC-DES-RPT-001) — 3D coordination outputs - RFI Review (PMC-MTG-MOM-012) — clarifications during construction
Process governance: ISO 19650 (BIM information management) Parts 1-5; ISO 9001:2015 Clause 7.5 (documented information) + 8.3 (design and development). For large infrastructure projects, the Common Data Environment (CDE) software (Aconex, Procore, BIM 360 Document) typically automates transmittal generation.
