What you need
The problem this service can help solve
Architecture and engineering firms may need discipline-model production under an established BIM execution plan. Before work begins, the client should define the model use, disciplines, LOD by element, model area, software version, coordinates, naming, exchange formats, review milestones, and licensed or qualified reviewer. The source package may include approved drawings, specifications, standards, calculations, surveys, and existing reference models. Brownsofts reassesses effort when those inputs or the approved model boundary change materially rather than silently absorbing repair, coordination, platform, or output work. The handoff includes final native and exchange files with unresolved issues and model-use limitations documented.
Service overview
About BIM Modeling (LOD 200–400)
The agreed output set includes discipline or federated BIM models created or updated from client-approved drawings, specifications, standards, and reference models; elements modeled to the agreed LOD by system, phase, zone, or model-use requirement rather than one blanket level; and final native and exchange files handed off with scope, unresolved issues, and model-use limitations documented. LOD must be defined by element and intended use; LOD 200, 300, 350, and 400 imply different geometry, information, coordination, and reliance expectations. The BIM execution plan should establish authoring software and version, coordinates, model segmentation, naming, exchange formats, common data environment, and issue workflow. Apparent conflicts are logged for the client's designated reviewer rather than treated as new design instructions. Brownsofts is not the architect or engineer of record. The client's licensed or otherwise qualified professionals retain design authorship, calculations, code interpretation, survey authority, professional review, approval, sealing, and construction responsibility where applicable.
Buyer guidance
When this service makes sense
Disciplines, model area, and element count should be documented before scope and schedule are confirmed. This service can support architecture or engineering firms adding discipline-model production under an established BIM execution plan. Required LOD by element and milestone should be confirmed alongside source readiness, access boundaries, and the owner for consolidated review and exceptions.

Service process
How the work moves forward
- 01
Establish the working brief
The client confirms the intended use of BIM Modeling (LOD 200–400), applicable standards, decision boundaries, one owner for consolidated review, and this scope driver: Disciplines, model area, and element count.
- 02
Audit inputs and dependencies
Brownsofts checks source completeness, access, versions, and unresolved decisions against this key consideration: LOD must be defined by element and intended use; LOD 200, 300, 350, and 400 imply different geometry, information, coordination, and reliance expectations.
- 03
Prepare the first controlled output
Brownsofts prepares an initial sample for review: Discipline or federated BIM models created or updated from client-approved drawings, specifications, standards, and reference models. The client confirms interpretation and quality standards before Brownsofts completes the remaining files.
- 04
Complete scoped production
After the initial direction is confirmed, Brownsofts advances the remaining work and applies documented checks to this related output: Elements modeled to the agreed LOD by system, phase, zone, or model-use requirement rather than one blanket level.
- 05
Coordinate review and revisions
The client returns consolidated comments against a named version, with this technical boundary guiding decisions: The BIM execution plan should establish authoring software and version, coordinates, model segmentation, naming, exchange formats, common data environment, and issue workflow.
- 06
Package the handoff
The final package records status, unresolved items, and the agreed receiving files or logs, including this scoped result: Final native and exchange files handed off with scope, unresolved issues, and model-use limitations documented.
Client inputs
What to prepare before scoping
Clear source material and a named decision owner help Brownsofts scope the work accurately.
- Provide the current client-approved drawings, models, surveys, specifications, markups, and standards needed to produce discipline or federated BIM models created or updated from client-approved drawings, specifications, standards, and reference models.
- Applicable CAD, BIM, rendering, measurement, or file standards for this requirement: LOD must be defined by element and intended use; LOD 200, 300, 350, and 400 imply different geometry, information, coordination, and reliance expectations.
- A statement of intended use, required detail or LOD, issue milestones, and the licensed or qualified reviewer responsible for approval.
- Provide one consolidated set of comments and decisions for elements modeled to the agreed LOD by system, phase, zone, or model-use requirement rather than one blanket level.
- Handoff requirements covering this final scoped result: Final native and exchange files handed off with scope, unresolved issues, and model-use limitations documented.
Timeline
Timing guidance
Timing for BIM Modeling (LOD 200–400) is set after input readiness, production volume, technical complexity, dependencies, client review windows, and the number of controlled revision cycles are understood. A backlog or incomplete source set may be divided into stages so assumptions and exceptions are resolved before the full queue or file package advances.
