Record Information
Project Closeout Information
What Was Designed and What Was Built May Not Be Identical
Construction projects change.
Routing may move, equipment may change, openings may be revised, field conditions may require adjustments and approved construction decisions may differ from earlier design documents.
As-built documentation incorporates reliable closeout information so project records more clearly represent the documented final condition.
Design Information → Construction Changes → Record Information
Documented project changes
incorporated into controlled
models and drawings.

As-built scope can be aligned to the available closeout information, disciplines and required handover deliverables.

Drawing information revised to incorporate documented project changes.
MEP As-Built Documentation
Mechanical, electrical, plumbing and fire-protection information updated from closeout records.

Multidiscipline As-Builts
Record Information Across Connected Building Systems
Architecture
Walls, openings,
room layouts,
ceilings and
documented architectural changes.
Structure
Structural project information
updated from
approved closeout sources.
Mechanical
Ductwork,
piping, equipment
and documented field changes.
Electrical
Electrical equipment,
containment and
documented distribution changes.
Plumbing
Water,
drainage and
project-defined plumbing updates.
Fire Protection
Documented fire-protection
system changes
incorporated where supplied.
Equipment
Installed equipment
information updated
where confirmed
by project records.
Asset Information
Project-defined asset data
prepared where included
in the handover scope.
Record Information Control
A Final Drawing Set Does Not Automatically Mean It Reflects Final Construction
Drawings may be marked final while field changes, redlines or approved construction revisions remain outside the document set.
Record documentation therefore requires reconciliation between available design information and reliable closeout records.
Design Baseline
Understand which model
or drawing revision
forms the starting point.
Approved Change Information
Incorporate field changes
from reliable
and approved project sources.
Conflicting Records
Different redlines
or closeout documents
may require clarification
before model updates.
Verification Status
Unverified conditions
should not silently
become confirmed record information.
As-Built Workflow
From Construction Changes to Controlled Record Information
01
Collect
Gather design files, redlines, RFIs and closeout records.
02
Compare
Review differences between design and documented construction.
03
Clarify
Identify conflicting, incomplete or uncertain closeout information.
04
Update
Incorporate supported changes into models and drawings.
05
Validate
Review model, drawings and source consistency.
06
Handover
Package agreed record information for closeout delivery.
Closeout Inputs
Typical Information Used for As-Built Updates
Redline Drawings
Field-marked
or project-approved
construction changes.
Revised Drawings
Approved revised
design or construction
documentation.
RFIs
Project clarifications
that affected
final installed conditions.
Change Records
Approved project
change information
relevant to record documentation.
Contractor Markups
Supplied trade
or contractor
closeout information.
Site Photos
Supporting visual
context where
relevant and reliable.
Point Clouds
Reality-capture information
where included
in the agreed workflow.
Existing BIM Models
Project models
used as the
baseline for updates.
Record Deliverables
Typical As-Built & Closeout Outputs
As-Built Revit Models
Updated BIM models reflecting supplied reliable closeout information.
Record Drawing Sets
Plans, sections, elevations and project drawings updated to the agreed scope.
MEP As-Built Drawings
Mechanical, electrical, plumbing and fire-protection record information.
Architectural As-Builts
Updated architectural model and drawing information.
Structural Record Information
Structural project documentation revised from supplied closeout sources.
Digital Handover Model
Record model prepared for project-defined handover use.
Asset Information
Project-defined asset data included where part of scope.
Closeout Drawing Package
Controlled documentation organized for final project delivery.
Change Reconciliation
Every Documented Change Needs a Clear Record Path
STEP 01
Source Identified
Determine where
the closeout change
was documented.
STEP 02
Change Interpreted
Understand the
documented effect
on project information.
STEP 03
Model Updated
Incorporate supported
change into
the relevant BIM model.
STEP 04
Drawings Updated
Reflect model
or documented change
in required sheets.
STEP 05
Cross-Checked
Compare drawings,
model and
supporting closeout information.
STEP 06
Uncertainty Flagged
Keep unresolved
conditions visible
for clarification.
STEP 07
Record Status Confirmed
Confirm information
included within
the agreed record scope.
STEP 08
Handover Package Issued
Organize final
model and drawing
deliverables for closeout.
As-Built QA / QC
Record Information Should Be Traceable to Its Source
As-built quality depends on the relationship between closeout source information, updated models and final drawings.
A visually clean final model should not hide missing or uncertain construction information.
Source Traceability
Confirm changes
are supported by
supplied closeout information.
Model Consistency
Review updated
geometry and
project information.
Drawing Consistency
Confirm sheets
align with
updated record information.
Revision Control
Maintain visibility
of the project
closeout revision state.
Unverified Conditions
Avoid representing
unsupported conditions
as confirmed information.
Handover Completeness
Review required
closeout files
before final issue.
Project Applications
As-Built Documentation for Project Closeout & Future Use
Construction Closeout
Final models
and drawings organized
around documented project changes.
Facility Operations
Record building information
available for
later operational workflows.
Future Renovation
Existing record information
available as
a starting reference.
Retrofit Planning
Updated project information
supporting future
building-system modifications.
Asset Information
Project-defined
asset information
connected to handover workflows.
Digital Archive
Structured closeout information
retained for
future project reference.
Record Reliability
As-Built Documentation Is Only as Reliable as the Available Closeout Information
Model updates can represent documented project information.
They cannot independently verify concealed construction, undocumented field changes or conditions not supported by reliable project records.
Documented Condition
Information supported
by approved closeout
or field records.
Observed Condition
Information supported
by available
visual or reality-capture data.
Unverified Condition
Information that
remains uncertain
should not be silently confirmed.
Future Engineering Use
Record BIM does not
replace project-specific
verification for future design.

Frequently Asked Questions
As-Built BIM FAQs
What is the difference between design drawings and as-built drawings?
Design drawings document the intended project design. As-built or record drawings incorporate available reliable information about documented construction changes and final project conditions.
Can redline drawings be converted into final as-built drawings?
Yes. Approved redlines can be incorporated into drawings and BIM models as part of the agreed closeout workflow.
Can an existing Revit model be updated for project closeout?
Yes. Existing models can be revised using reliable project changes, redlines, revised drawings, scan information and other supplied closeout records.
Can MEP systems be updated in the as-built model?
Yes. Mechanical, electrical, plumbing and fire-protection information can be updated where reliable construction records are available.
Can laser scan data support as-built BIM?
Yes. Reality-capture or point-cloud information can support existing-condition verification where included in the agreed project workflow.
Does an as-built model verify every hidden condition in the building?
No. Concealed or undocumented conditions should not be treated as confirmed unless supported by reliable project or survey information.
