01
One coordination reference
Bring defined discipline models into an agreed coordinate and exchange environment.
BIM Modeling & Coordination
Make building information coordinated, reviewable and usable.
Programmatic structures BIM work around defined disciplines, information requirements, exchange rules and coordination responsibilities. The engagement separates model production, issue detection and design authority so a coordinated model is not mistaken for unqualified engineering approval.
Inside the delivery
Coordinate information through owned issue cycles
Establish purpose, source authority and standards first; then model, federate, assign issues and validate each agreed exchange milestone.
- 01
Define requirements
Agree model uses, disciplines, sources, coordinates, information needs, standards, exchange formats and approval roles.
Output
BIM scope, responsibility and information plan
- 02
Produce and validate models
Create or update scoped models and run model-health, naming, coordinate and information checks.
Output
Discipline model release and validation record
- 03
Federate and coordinate
Combine models, apply agreed clash rules, classify issues and assign decisions to responsible owners.
Output
Federated model and owned issue register
- 04
Resolve and hand over
Track accepted changes, rerun checks and deliver agreed models, reports, exceptions and downstream derivatives.
Output
Accepted model package and coordination record
Controls across the workflow
- Model-use definition
- Source and design authority
- Coordinate and exchange rules
- Owned issue register
Decisions that shape the scope
- What must the model support?
- Define the decisions and downstream uses before selecting geometry and information requirements.
- Who resolves each coordination issue?
- Assign design and approval ownership by discipline; the coordinator records and tracks decisions rather than inventing them.
Before you commit
Is this the right engagement?
Use BIM modeling and coordination when building information must support controlled multidisciplinary review, exchange, visualization or handover beyond disconnected drawings and geometry.
Reference worksheet only. Your signed proposal and statement of work define the engagement.
- What we need from you
- Provide model uses, discipline scope, approved sources, coordinates, standards, information requirements, native and exchange formats, milestones, issue workflow, qualified design authorities and acceptance owner.
- How you accept the work
- Validate agreed coordinates, naming, model health, required elements and attributes, exchange behavior, coordination rules, issue status and documented exceptions at each delivery milestone.
- Scope & alternatives
- BIM production and coordination do not replace discipline design authority, engineering certification, fabrication approval, site verification or constructability review unless those responsibilities are explicitly and competently scoped.
Overview
A useful BIM model is governed by purpose and information requirements
BIM is more than three-dimensional geometry. Model elements, classifications, attributes, coordinates, issue status and exchange rules must support a defined use such as design coordination, quantity workflows, visualization or asset handover. We establish those uses and responsibilities before modeling, then record conflicts and decisions through a controlled coordination cycle.
- 01Architectural and defined multidisciplinary modeling
- 02Structural and MEP model coordination where scoped
- 03CAD or reference information to BIM
- 04Federated model review and clash workflows
- 05Model standards, naming and exchange requirements
- 06BIM-to-visualization and handover preparation
What changes
What governed BIM delivery provides
02
Visible issues with owners
Record clashes, information gaps and decisions instead of treating an automated report as resolution.
03
Information matched to use
Model the geometry and attributes needed for the agreed purpose rather than maximizing detail without value.
04
A traceable handover
Deliver agreed models, reports, exceptions and responsibility notes with known limitations.
Capabilities
Model production, coordination and handover
Strategy matters only if the implementation holds up. These are the technical and operational capabilities we bring into the engagement.
BIM model production
Create or develop models against agreed source information, discipline and information requirements.
- Architectural models
- Defined structural or MEP scope
- CAD and drawing conversion
- Family and object standards
Federation and coordination
Bring models together, test agreed rules and manage issues to assigned resolution owners.
- Coordinate and origin review
- Model federation
- Clash rule sets
- Issue tracking and status
Information and exchange
Define what must be present and how models move between project participants.
- Naming and classification
- Level of information requirements
- IFC and native exchange planning
- Model health and delivery checks
Downstream preparation
Prepare controlled derivatives for visualization or other explicitly defined uses.
- BIM-to-CGI handoff
- Geometry filtering
- Asset and material mapping
- Handover documentation
Comparison
Modeling, coordination and approval are different responsibilities
| Activity | Produces | Does not automatically provide |
|---|---|---|
| BIM modeling | Structured geometry and information from approved sources | Design authorship or engineering certification |
| Clash detection | Potential conflicts based on agreed tests and tolerances | A resolved design or construction decision |
| BIM coordination | Federated review, assigned issues and tracked status | Authority to approve every discipline change |
| BIM visualization | Presentation assets derived from controlled model information | A construction-ready or fabrication model |

Pricing
Engagement options and pricing factors.
BIM scope depends on discipline, model purpose, source condition, required information level, project area and complexity, exchange formats, coordination cycles, clash rules, update frequency and handover requirements. We estimate only after defining what the model must support.
Defined model package
A bounded discipline, source set, information requirement and delivery milestone.
Coordination programme
Recurring federation, issue cycles and model releases across an agreed project period.
Frequently asked questions
BIM modeling and coordination questions
01What are BIM modeling services?
What are BIM modeling services?
BIM modeling services create and manage structured digital building information for an agreed purpose, including geometry, attributes, classifications, exchange rules and model-delivery requirements.
02What is BIM coordination?
What is BIM coordination?
BIM coordination brings discipline models into a shared review process, applies agreed checks, records issues, assigns owners and tracks decisions. Coordination identifies and manages conflicts; it does not resolve design authority by itself.
03What is MEP BIM modeling?
What is MEP BIM modeling?
MEP BIM represents mechanical, electrical and plumbing systems using agreed geometry and information. Its scope, design source, level of detail and qualified approval responsibilities must be explicit.
04What is the difference between BIM and CAD?
What is the difference between BIM and CAD?
CAD commonly represents geometry through drawings or objects, while BIM organizes building elements and related information for defined project uses. The practical difference depends on how the model is structured and governed.
05Can CAD drawings be converted into a BIM model?
Can CAD drawings be converted into a BIM model?
Yes, when the source drawings are sufficiently current and complete. Conversion still requires decisions about element types, levels, coordinates, information requirements, unresolved conflicts and intended model use.
06Does a clash-free model guarantee constructability?
Does a clash-free model guarantee constructability?
No. Clash results depend on model completeness, rules and tolerances, and constructability includes access, sequence, tolerances, temporary works and field conditions beyond basic geometric checks.
