BIM questions

What contractors can expect from ModelMason BIM support.

Technical capacity with clear ownership, reporting, and coordination follow-through.

How do I choose a BIM company for my trade?

Choose a BIM provider that defines the trade scope, model requirements, review process, and deliverables before work begins. Agree which responsibilities your BIM service includes. If you need a Revit modeling company, confirm the required software version, file standards, and who approves technical changes.

How are BIM modeling pricing and turnaround agreed?

We review the trade scope, project size, available drawings, model detail, software version, coordination workload, and required delivery dates before agreeing pricing and a schedule. The scope identifies deliverables, review points, revision expectations, and exclusions.

Can you create a 3D trade model from 2D drawings?

Yes. ModelMason can develop a trade-specific Revit model from current drawings, specifications, and scope information. We agree on model detail, software version, coordination requirements, and deliverables before modeling begins.

What should a subcontractor provide to start modeling?

Share current drawings, specifications, addenda, your trade scope, available reference models, and the project's BIM requirements. Include the required Revit version, model detail, file format, and coordination deadline when available.

What 3D modeling deliverables can be included?

The agreed scope can include a trade model, model updates, coordination reports, issue logs, drawing markups, and shop-drawing support. Your team retains technical approval; a model or coordination review does not replace required engineering or field verification.

What BIM services does ModelMason provide?

ModelMason provides Revit model development, composite-model management, structural and MEPFP clash detection, issue tracking, coordination reports, drawing support, and coordination-meeting ownership.

Which software does ModelMason use for BIM coordination?

ModelMason has delivered coordination work using Navisworks, Revit, and AutoCAD MEP, with reports and issue logs organized around the client's project workflow.

Does ModelMason support general contractors and specialty contractors?

Yes. ModelMason can manage composite coordination for a general contractor or provide modeling, coordination, and documentation support for a specialty trade contractor.

Can ModelMason lead BIM coordination meetings?

Yes. ModelMason can run recurring coordination meetings, assign action items to responsible subcontractors, track model updates, and maintain visibility into open issues.
