Readiness for Delivery
Beyond Clash Detection
Geometry Can Fit and Still Be Difficult to Build
Clash-free geometry does not automatically mean installation will be practical.
Equipment may require access for installation, replacement or maintenance. Services may need working space. Structural openings may need to align with routing. Ceiling zones may become too congested for practical installation.
Constructability review brings these broader project conditions into the BIM coordination process before they become field-level constraints.
Coordinated Geometry Is Only One Part of Buildability
Access • Installation • Clearances • Interfaces • Maintenance

Buildability Control
No Clash Does Not Automatically Mean No Construction Problem
Two model elements may not physically intersect, but practical installation can still be difficult.
Access, maintenance, replacement paths, working space and sequencing often require review beyond automated clash detection.
Geometric Clearance
Does the system
physically fit
within the available space?
Installation Clearance
Is there enough
practical space
to install it?
Maintenance Clearance
Can project-defined
service access
be maintained?
Replacement Access
Where required,
can major equipment
be removed
or replaced?
Constructability Workflow
Review Practical Conditions Before They Become Field Constraints
01
Gather
Review models, drawings and relevant project information.
02
Federate
Bring relevant disciplines together for coordinated review.
03
Inspect
Review access, clearances, interfaces and congested conditions.
04
Record
Document relevant constructability observations and locations.
05
Resolve
Responsible teams review and update project information.
06
Verify
Recheck selected resolved conditions before issue closure.
Access & Clearance Review
Space Around Equipment Can Be as Important as the Equipment Itself
Installation Access
Review whether selected components can reasonably reach their intended installation location based on available project information.
Service Access
Review project-defined access around equipment that requires inspection, servicing or maintenance.
Working Clearances
Review defined working zones around selected technical equipment.
Access Panels
Review the relationship between concealed services and project-defined access requirements.
Equipment Removal Paths
Where project requirements define future replacement needs, assess available movement paths.
Ceiling Access
Review congested above-ceiling conditions where access may be constrained by multiple systems.

Constructability QA
Practical Review Depends on Current, Coordinated Information
Constructability observations are only meaningful when the project information being reviewed represents the intended design and coordination stage.
Model revision, scope, coordinates, equipment information and project assumptions should remain visible throughout the review.
Model Revision
Confirm intended
project models
are being reviewed.
Coordinate Alignment
Confirm relevant
disciplines align
for meaningful review.
Equipment Information
Use project-defined
equipment information
where access matters.
Clearance Basis
Review against
supplied or
project-defined
clearance requirements.
Issue Traceability
Keep findings
connected to
model locations
and revisions.
Resolution Status
Distinguish open,
proposed,
approved
and verified conditions.

Frequently Asked Questions
Constructability Review FAQs
What is BIM constructability review?
BIM constructability review examines available project models and design information for practical construction conditions such as access, clearances, system interfaces, congestion, equipment movement and installation constraints.
How is constructability review different from clash detection?
Clash detection focuses primarily on geometric and clearance conflicts. Constructability review considers broader practical issues including access, installation sequence, maintenance zones and project interfaces.
Can constructability review identify maintenance-access problems?
Yes, where project-defined maintenance or service-clearance requirements are available, selected access conditions can be reviewed.
Can equipment replacement paths be reviewed?
Yes, where equipment information, project requirements and intended access paths are sufficiently defined.
Can structural openings be reviewed during constructability coordination?
Yes. Project-defined sleeves, penetrations, openings and system-to-structure interfaces can be reviewed as part of the coordination scope.
Does constructability review replace the contractor's field planning?
No. BIM constructability review supports project coordination from available digital information. Field execution, temporary works, site safety, construction means and methods and contractor planning remain with the appropriate project parties.
