Proposed Design Modeling in OpenBuildings Designer

From your design team's drawings to accurate structural and architectural models in OpenBuildings Designer.

  • Native OpenBuildings models, no conversion
  • Built into your existing condition model
  • Real data on every element: material, grade, weight
  • Updated in place at every design submission
  • Built to your standards, inside your ProjectWise
  • Light, clean files that keep drawing production fast

Our process

From Design Issue to Proposed Design Model

Your engineers design it. We model it, every time they issue drawings.

  1. Compare the new issue with the last one

    We go through the issued drawings and mark what's new, changed or removed before the model is touched.

    Why: the model changes only where the design did, and nothing slips through.

  2. Work through open points before modeling

    We go through conflicts and gaps with your engineers, each with its drawing references.

    Why: your engineers make the call, so nothing is modeled on a guess.

  3. Model the changes in place

    Changes go into the same model, structure before architecture, each element with its data.

    Why: one model through every issue means no rebuilds and no second copy to keep in step.

  4. Check every changed element against its drawing

    Sizes, levels and locations are checked against the issued drawings before anything leaves our hands.

    Why: the model matches the design that goes into your submission.

  5. Hand over for your submission

    The model is handed over in your ProjectWise, ready for drawing production, with any questions still open listed.

    Why: you know exactly what's done and what's waiting on your engineers.

What we model

Structural & Architectural Elements We Model in OpenBuildings

We choose the tool for each element by what it gives back in your drawings, schedules and data, and every element carries the Family and Part your standard requires.

ElementHow we model itData it carries
Structural
Steel members: columns, beams, bracingPlaced from the structural section library. Sections your engineers specify that aren't in it are added as user shapes first, so every member reports its real section.SectionGradeMaterialWeightCoating
Steel coping & platesMembers coped automatically where they meet, with set flange and web clearances. Base plates and connection plates modeled where your design details them.SectionGradeMaterial
Concrete columns, beams, walls, slabs & footingsModeled to the sizes, levels and grades on your structural drawings. Footings carry the Foundation family, so they schedule separately from the structure above.GradeMaterial
Openings & penetrationsPlaced as penetration components from the catalog, so every opening is a real object that cuts the slab or member, shows in plans and sections, and can be scheduled.Catalog typeSize
Stair & elevator structuresStair stringers, landings and elevator shaft framing, tied to the floors and grids they serve.SectionGradeMaterial
Changes to the existing structureModeled into the existing condition model. Elements being removed get the Demolition Part, and retained ones keep the Existing Part.Existing PartDemolition Part
Architectural
Walls, doors & windowsIntelligent walls joined with T, L and cross connections. Doors and windows from the project catalog, so openings move with them.Catalog typeSizeFrameSwing
Floors, platforms, ramps & roofsBuilt as forms and solids, so slopes, ramps and drainage falls stay easy to reshape as the design develops.Instance Data
StairsStair tool with shared stair settings, so every stair matches and its symbols update in the drawings.Stair type
RailingsRailing types from the project dataset. New types are added to the library for reuse.Railing typeHeight
Curtain walls & glazingTypes, panels and mullions from the project catalogs. Doors and windows go straight into the curtain wall, and the panels adjust around them.Curtain wall typePanelsMullionsGlazing
Objects & caseworkPlaced from your project's own object set, such as benches, bins and furniture.Object type

Getting started

Let's Scope Your Proposed Design Modeling Project

Share the information you have. We'll review it and send you a quote.

Design drawings

Structural and architectural plans, sections, elevations and details from your latest issue.

Sketches and markups

Engineers' sketches and redlined markups for anything not yet on a drawing.

Existing condition model

The model the new work goes into. No model yet? We build it first with existing condition modeling.

BIM Execution Plan & CAD standard

The level of development, attributes, levels and naming your project requires.

Access to your ProjectWise

The project workspace, with its catalogs, cells and section library.

Your submission schedule

The dates of your upcoming design submissions, so the model is ready for each one.

Why Choose BIM Global for Proposed Design Modeling

Bentley-native from the first element

We model in OpenBuildings Designer, the same environment your drawing production and ProjectWise run in. Every element stays native and editable, with its data intact.

Structural expertise on rail and transit

Led by an industry expert with a career mostly in structural work, including station upgrades, bridges, viaducts and tunnels modeled in OpenBuildings alongside the design teams. Your drawings are read the way your engineers meant them.

Models that keep drawing production fast

Each element is built with the tool that keeps the file light, so plans, sections and elevations cut quickly and your drawing team never waits on a lagging model.

Ready for every stage after design

The proposed design model is built into your existing condition model, then carries on into drawing production, construction and the as-built record without a rebuild.

Who it's for

Who Uses Proposed Design Modeling

Design

Architecture & Structural Engineering Firms

Your engineers have the design, the next submission is due, and your modelers are already booked. We build the model so your team stays on the design.

Construction

General Contractors & Design-Build Teams

Design is underway on a station upgrade, renovation or accessibility package, and the model has to keep pace with every submission.

Consulting

BIM & Engineering Consultancies

Your team works in Bentley software and needs extra structural or architectural modeling capacity, built to the same standards your own team uses.

Proposed Design Modeling FAQ

Who makes the design decisions?

Your design team. Your architects and engineers design the work and keep their names on it. We model what their drawings show, and we work through any open point with them before it's modeled.

What happens when the drawings conflict or leave something open?

We work through it with your team, with the drawing references in hand, and model what your engineers decide. Nothing is filled in on a guess, so the model always matches your design team's intent.

Can you work alongside our own modelers?

Yes. We work to the same standards inside your ProjectWise, and can take on a full package or extra capacity when a submission peaks.

What LOD are proposed design models built to?

Typically LOD 300, set per element type, or the level your BIM Execution Plan sets: each element at its designed size, shape and location. Fabrication-level LOD 400 is built from your contractors' shop drawings once construction starts.

Is the model ready for drawing production?

Yes. Views and display rules are checked before handover, so your team can cut plans, sections and elevations straight away. If you'd like us to produce the drawings too, see Drawing Production.

Can you work inside our ProjectWise and to our CAD standard?

Yes. We confirm your standard at kickoff (levels, naming, catalogs, cells and attributes) and model inside your ProjectWise environment, so your files stay in one place.

How is proposed design modeling priced?

Every project is scoped first, then quoted. Cost and timeline depend on the size of the design, the level of development, the disciplines involved and how many design stages the model is updated for, and we confirm both in your quote.
