Scan-Validated Accuracy
Geometry is checked against the registered cloud so dimensions reflect installed reality, not assumptions.

As-Built BIMVerified From Reality
We update or rebuild your BIM to match installed conditions — validated against registered scans — so owners, renovators and operators work from a trustworthy digital record, not outdated design intent.

Problem Statement
Design Models Rarely Match Installed Reality
Construction changes, RFIs and field decisions leave design models outdated. Owners and renovators need verified as-built records — not assumptions — before renovating, leasing or operating a facility.
Our Solution
Scan-Verified As-Built Documentation
BIMZ Studio aligns your model to registered scans or site surveys, updates geometry and data to as-installed conditions, and delivers LOD 400–500 packages suitable for handover, FM and future works.

Benefits
Why Teams Choose Our As-Built BIM Service
As-built models that close the gap between design intent and what was actually built — ready for FM, leasing and future works.
LOD Matched to Handover Needs
From coordination-level updates to LOD 500 asset-ready models, scoped to how you will use the deliverable.
Multi-Discipline Coverage
Architecture, structure and MEP can be updated together so the federated as-built tells one coherent story.
Drawing & Data Extract
Plans, sections and schedules regenerated from the verified model for record sets and FM packs.
Audit-Ready QA Pack
Deviation summaries and completeness checklists ship with every as-built delivery.
Workflow
Our As-Built BIM Process
A six-stage pipeline that turns design or partial models into verified as-built BIM.
01
Discovery
We confirm scope, LOD, coordinate system, deliverable formats and project standards before any modeling begins.
02
Point Cloud Review
Registered scan coverage, density and control are reviewed so modeling tolerances are realistic and agreed.
03
Planning
Discipline strategy, naming, worksets and phasing are locked so the model structure matches your BEP.
04
Modeling
Elements are authored directly against the reference cloud at the agreed LOD with continuous self-checks.
05
QA
Deviation analysis, completeness review and clash passes run before anything is marked ready for handover.
06
Delivery
Native files, IFC/exports, drawings and a QA summary ship with revision rounds included in scope.
Methodology
How As-Built BIM Is Scoped
Practical definitions, limitations and commercial factors — written so they stay true from one project to the next.
What is as-built BIM?
As-built BIM records installed conditions rather than design intent. It is often produced by updating a model against a registered point cloud (Scan-to-BIM) or by rebuilding categories the scan supports.
Who needs it
Owners, renovators and operators who cannot rely on outdated design models for handover, leasing, FM or future works.
Typical deliverables
A verified model at the agreed LOD, plus drawings or IFC when those extracts are in the proposal. Registration quality still limits what can be verified.
Next step
If this service matches your brief, request a scoped proposal. Commercial terms depend on the project requirements you submit.

FAQ
Frequently Asked Questions
Answers to what teams most often ask before starting a as-built bim project.
Do we need an existing design model?
Helpful but not required. We can update your design model to as-built conditions or rebuild from scan data alone.
What LOD is typical for as-built handover?
Most handover packages are LOD 400–500, depending on whether you need fabrication-level detail or FM-ready asset geometry.
How long does an as-built project take?
Typical single-building packages ship in 1–3 weeks after scope confirmation, depending on area, disciplines and scan quality.
Can you include MEP as-built?
