Construction Documentation
Hồ sơ bản vẽ thi công
Produce consistent, auto-updating shop drawings, installation drawings, and schedules directly from the BIM model. Model changes instantly reflect in all drawings.
Common tools
Revit (sheet set), Tekla Structures (drawing tool)
Value delivered
Eliminates errors from out-of-sync drawings — one of the most common rework causes in construction
Adoption in Vietnam
Clearest benefit for Vietnamese engineers — many firms adopt BIM primarily for this reason.

Rationale: Hồ sơ bản vẽ thi công / shop-drawing production across all disciplines. G3/A2/D1 at ST3 (construction document set); G4/A2/D2 at ST4 (fabrication-level drawings plus regulatory/authority documentation). Mirrors AIA CD → CA progression using LOD350–400.
What it really is
Construction documentation extracts shop drawings, installation drawings, detail sections and schedules directly from a completed BIM model instead of redrawing them by hand in 2D CAD. Every view and sheet is simply a "window" onto the same model — edit one object and every drawing, section and schedule derived from it updates automatically, with no file-by-file synchronising. This differs fundamentally from traditional 2D drafting, where each drawing is an independent file that must be kept in sync manually: here the drawing is a DERIVED PRODUCT of the model — the model is the source of truth, the drawing just one of many possible presentations of it. The use covers three core activities: setting a project-wide view/sheet convention, applying standardised annotation and symbols, and controlling versions at issue so the drawing set on site always matches the model at the exact moment it was issued — no earlier, no later.
When to use
Worthwhile once the design/construction model reaches a LOIN detailed enough to extract drawings from — especially for multidisciplinary works, projects with frequent in-construction design changes, or heavy use of prefabricated elements needing accurate drawings. In principle BIM is mandatory for new-build works Grade II and above under Art. 8(1)(a); but the real value only appears once issuing is version-controlled on a CDE, not when a single PDF is emailed out.
Prerequisites
- •A design/construction model at a LOIN detailed enough to extract drawings from — depends directly on Design Authoring
- •A model that has gone through multidisciplinary coordination with no serious hard clashes remaining — see 3D Coordination & Clash Detection
- •A BEP that has fixed the view-template, sheet-naming, paper-size and shared annotation/symbol conventions for the whole project
- •A CDE that distinguishes WIP / Shared / Published status so the correct version is locked at drawing issue
- •Staff able to configure sheet sets, view templates and model-linked schedules — not detach drawings to edit manually in another program

Outputs
Issued construction drawing set (shop / working drawings)
.pdf / .dwg → Construction contractor
Accepted when: Matches the model exactly at issue time, follows the presentation convention fixed in the BEP, has passed cross-checking before release
Material/element schedules pulled directly from the model
.xlsx / trong sheet → Cost task team · construction contractor
Accepted when: Every row traceable to a model object, no hand-typed or off-model rows
Drawing register with number, revision and approval status
.xlsx / trên CDE → All parties on the CDE
Accepted when: Every drawing has a traceable revision code and issue date; no two differing copies share the same number
Model locked at the version matching the issue date (issued-for-construction)
IFC + định dạng gốc → CDE · competent authority when required
Accepted when: Model frozen at the exact issue moment, verifiable back against the issued drawing set
General workflow
Set the view and sheet convention
Fix the view template, sheet naming, paper size, title block and sheet organisation in the project template. Skip this and every discipline sets up views differently — nobody can find anyone else's drawings.
BIM Manager · Revit (view template, sheet) → Project-wide view/sheet convention
Verify the model is clash-free and at the required LOIN
Confirm the model has been coordinated, has no serious remaining hard clashes, and objects carry enough information to extract a reliable drawing set.
BIM Coordinator · Navisworks Manage · Solibri → Model confirmed ready for drawing extraction
Place views per the fixed convention
Create plans, sections, elevations and details per the fixed view template and place them on sheets per the contractual drawing list — no ad hoc views outside the convention.
Discipline task team · Revit → Sheet set populated per convention
Apply standard annotation and symbols
Apply tags, notes, material symbols and dimensions using the project's standard families — not free-typed text or symbols detached from the model-linked tag system.
Discipline task team · Revit → Fully annotated drawings
Configure model-linked schedules
Build material, element, door and equipment schedules directly in the BIM software, filtered and sorted as required — never copy them to Excel for hand editing.
Discipline task team · Revit → Model-linked schedules
Cross-check before issue
Compare the drawing set about to be issued against the latest model, catching mismatches from stale views or outdated annotation. This is the last quality gate before drawings leave the office.
BIM Coordinator · Revit · Navisworks Manage → Drawing-to-model cross-check report
Lock the version and issue
Export PDF/DWG, assign the number and revision in the drawing register, lock the corresponding model version, then publish at Published status on the CDE — never send loose files by email or chat.
BIM Coordinator · Lead appointed party · Forma Data Management (CDE) → Issued drawing set, version locked
Diagram
↺ When the model changes, every view, sheet and schedule updates automatically — a construction drawing set is a controlled snapshot of a living model, not a one-off drawing
Common pitfalls
Drawings on site no longer match the latest model; the site builds to an outdated detail
Cause: Engineers hand-edit the 2D drawing after export (annotate, override, delete a dimension) instead of going back to fix the model
Fix: Absolutely no hand-editing of exported drawings; every change must be made in the model, then re-exported
Every discipline and every person names views and sheets differently
Cause: The view-template and sheet-naming convention was never fixed in the BEP before modelling started
Fix: Fix the view/sheet convention in the project template itself and enforce view templates instead of letting each view be set up freely
The contractor builds from an outdated drawing while the office has already issued a newer one
Cause: No version lock at issue — multiple PDF copies float around email and chat apps outside the CDE
Fix: Every issued drawing must pass through the CDE, be marked Published and locked to its exact corresponding model version
The schedule printed on the drawing does not match the actual quantities on site
Cause: The schedule was typed by hand or copied from a standalone spreadsheet, breaking the link to the model
Fix: Only accept schedules configured directly in the BIM software, live-linked to model objects
Measuring effectiveness
Sheets with a mismatch found at cross-check divided by total sheets in that issue
Benchmark: no independent benchmark — set an internal target
Compare design-error rate and rework cost between drawings extracted directly from BIM and traditional hand/2D-CAD drafting
Benchmark: Synthesis across multiple case studies: 50–60% fewer design errors and 40–50% lower rework cost; a pooled range from heterogeneous projects, useful as a directional signal, not a guarantee for any single project
Person-hours from a model change to a cross-checked, re-issued drawing set
Benchmark: no independent benchmark — set an internal target
Legal basis
There is NO specific requirement mandating any particular way of producing construction documentation in Decree 217/2026/NĐ-CP — construction_docs falls under Article 8 generally. Art. 8(1)(a) makes BIM mandatory for new-build works Grade II and above, from the feasibility-study or economic–technical report stage. The nuance most worth noting for this use sits in Art. 8(5)(b): once the competent construction authority is equipped to receive and use BIM data, the BIM model itself may replace paper documents with equivalent legal value — meaning that, over time, the paper or PDF drawing set is no longer the sole "original" to be kept; the model becomes the source of truth and the drawing just one presentation extracted from it. This is the direct legal basis for the core principle of this use: the drawing is a derived product of the model, never the other way around.
