Existing-Condition Intelligence
Existing Buildings Rarely Match Old Drawings Perfectly
Renovation and retrofit projects often depend on legacy drawings that may no longer reflect current site conditions.
Reality capture provides a measured digital reference that can support verification of geometry, service locations, structural conditions and project constraints.
The captured data can then become an input for Scan to BIM, renovation planning, coordination and construction documentation.

Reality Capture Capabilities
From Site Reality to Usable Digital Information
Scope can be aligned to the available scan data, project stage, required verification and downstream BIM workflow.
Point-Cloud Processing
Point-cloud information organized and prepared for review, model development and downstream use.
Scan Registration Support
Available scan datasets reviewed and organized within the intended project coordinate context.
Existing-Condition Review
Captured information used to support comparison against drawings, models or planned project conditions.
Renovation Survey Support
Existing-condition information structured for renovation and retrofit planning workflows.
Existing MEP Conditions
Reality information can support understanding of visible building-service locations and spatial constraints.
Structural Context
Captured building geometry can support review of visible structural conditions and interfaces.
Existing-Condition Documentation
Reality-capture information prepared as reference for model and drawing development.
Scan to BIM Preparation
Point-cloud information organized for transfer into the downstream Scan to BIM workflow.
Reality Capture Information
Digital Inputs That Can Support the Existing-Condition Workflow
Registered Point Clouds
Existing scan information
prepared within
a coordinated dataset.
Individual Scan Data
Available capture information
requiring project-specific
organization or review.
Existing CAD Drawings
Legacy project drawings
available for
comparison against reality data.
Existing BIM Models
Previous project models
requiring comparison
with current site information.
Survey Control
Project-provided
coordinate or survey
control information where available.
Site Photos
Supporting photographic
context for
existing-condition interpretation.
Markups
Field notes
and project-specific
observations.
Project Requirements
Defined areas,
disciplines and
downstream model requirements.
Reality Data Control
A Point Cloud Is Not Automatically a Verified BIM Model
Reality capture represents measured spatial information.
It still requires interpretation before becoming structured architectural, structural or MEP BIM information.
Capture Data
Point-cloud information represents
observed site geometry,
not automatically
classified BIM elements.
Visibility Limits
Hidden, obstructed
or inaccessible conditions
may not be represented
clearly in captured data.
Project Scope
Required areas
and systems should
be defined before
downstream modeling begins.
BIM Interpretation
Modeling decisions should
remain traceable
to the available
point-cloud and project information.
Reality Capture Workflow
From Existing Conditions to BIM-Ready Information
01
Define Scope
Identify areas, disciplines and required downstream use.
02
Capture / Receive
Obtain available reality-capture or point-cloud information.
03
Organize
Prepare scan information within the required project context.
04
Review
Check coverage, orientation and available site information.
05
Prepare Handoff
Organize point-cloud references for modeling or documentation.
06
Model / Document
Continue into Scan to BIM or other project workflows.
Reality Capture Applications
Existing-Condition Information for Project Decisions
Renovation
Existing geometry
used as reference
for planned building modifications.
Retrofit
Current spatial conditions
supporting upgrades
to existing facilities.
MEP Coordination
Existing service
and spatial context
supporting new routing decisions.
Existing-Condition BIM
Captured reality information
used as an input
for Scan to BIM.
Construction Verification
Available scan information
can support comparison
between planned
and observed conditions.
Digital Records
Existing-condition information
retained as
a digital project reference.
Typical Reality Capture Outputs
Information Prepared for Downstream Engineering Workflows
Organized Point-Cloud Data
Available reality-capture information structured for project use.
Registration / Alignment References
Project-specific coordinate context where supported by supplied data.
Existing-Condition References
Digital information prepared for design and renovation review.
Scan to BIM Inputs
Point-cloud information prepared for architectural, structural or MEP modeling.
Verification Views
Project views supporting comparison of existing conditions.
Digital Existing-Condition Record
Reality information maintained as a project reference for downstream use.
Reality Capture QA
The Quality of the Handoff Depends on the Quality of the Source Data
Downstream BIM teams need to understand what was captured, what remains uncertain and which parts of the building were not visible.
That context should remain visible rather than disappearing during model development.
Coverage Review
Confirm required areas
are represented
in available data.
Alignment
Review point-cloud
orientation and
project reference context.
Data Visibility
Identify obscured
or unavailable
existing conditions.
Source Comparison
Compare scan information
against available
legacy project documents.
Scope Control
Keep modeled
or reviewed areas
aligned to defined scope.
Handoff Readiness
Confirm source information
is organized
for downstream modeling.
Project Environments
Reality Capture Across Existing Facilities
Commercial Buildings
Existing office,
retail and mixed-use
renovation environments.
Healthcare
Existing-condition information
for technically complex
healthcare spaces.
Industrial Facilities
Reality capture support
for existing production
and utility environments.
Data Centers
Existing technical
and mission-critical
facility conditions.
Residential & Hospitality
Renovation and
redevelopment workflows
for existing properties.
Institutional Buildings
Existing schools,
campuses and
public-building environments.
Data Interpretation
Captured Geometry Is Not the Same as Engineering Verification
Reality-capture information can document visible spatial conditions.
It does not automatically establish concealed construction, material properties, system performance or engineering compliance.
Visible Conditions
Reality capture reflects
conditions represented
in the available dataset.
Concealed Conditions
Hidden elements
should not be assumed
from surface information alone.
Engineering Information
Structural or system
engineering conclusions require
appropriate technical review.
Model Interpretation
BIM development
should distinguish
measured information
from documented assumptions.

Frequently Asked Questions
3D Laser Scanning FAQs
What is 3D laser scanning used for?
Reality capture can provide measured existing-condition information for renovation, retrofit, BIM modeling, coordination and digital documentation workflows.
What is a point cloud?
A point cloud is a digital collection of spatially measured points representing captured physical geometry.
What is the difference between laser scanning and Scan to BIM?
Laser scanning or reality capture provides existing-condition spatial data. Scan to BIM uses that information as reference to develop structured BIM models.
Can reality capture support renovation projects?
Yes. Existing-condition information can support renovation, retrofit and redevelopment workflows, particularly where legacy drawings may not represent current site conditions.
Can point clouds be compared with existing drawings or models?
Yes. Available point-cloud information can support comparison with existing CAD, BIM or design information within the agreed project scope.
Does laser scanning reveal concealed building conditions?
Not automatically. Standard reality capture records visible geometry represented by the dataset. Concealed construction or internal system conditions may require other investigation methods.
