InfraGrid 3D

InfraGrid 3D is a browser-based civil and utility BIM tool for roads, drainage, underground utilities, and public lighting. It helps civil engineers, BIM managers, and utility designers route infrastructure, inspect live long sections, run on-demand clash checks, and export geometry to Revit, IFC, or DXF.

InfraGrid 3D

Browser-based civil and utility BIM

InfraGrid 3D is a browser-based civil and utility BIM tool for designing roads, drainage, underground utilities, and public lighting. Civil engineers, BIM managers, and utility designers can route infrastructure in a web tab, inspect live long sections, and review relationships between roads and services in one model.

Its central workflow is route, verify, and export: set out a road or service corridor, adjust the alignment and associated geometry, read the resulting long section, and run a clash check when required. The product is positioned as a complement to desktop tools rather than a replacement for every Civil 3D module; the source specifically excludes EPA SWMM and catchment analysis.

Core features

Road and corridor design

Create carriageways and junction-related elements such as kerbs, construction build-up, camber, UK markings and signs, lay-bys, and widenings. Alignment edits update the corridor model.

Civil and utility modelling

Model drainage, underground utilities, chambers, and public lighting in the same browser-based civil and utility model.

Live long sections

Read a live long section while editing the road and services, allowing cover, bends, and vertical relationships to be reviewed before construction.

On-demand clash detection

Run hard and soft clash checks on pipes and chambers when the engineer chooses to activate them, rather than relying on an always-on check.

Native export and Revit workflow

Move project geometry into downstream workflows through native Revit geometry and IFC or DXF export. The Revit add-in can send DirectShape geometry to project coordinates.

Browser access and site context

Open and review the model in a web tab, with Mapbox site context listed as part of the product and large IFC/CAD models described as streamable for navigation.

Practical use cases

  • Early road and junction layout

    Develop a road corridor with kerbs, build-up, camber, junction elements, lay-bys, or widenings, then inspect the updated corridor in long section as the alignment changes.

  • Underground service coordination

    Coordinate drainage, utility routes, chambers, and lighting around a road without maintaining separate preliminary models for each service discipline.

  • Design verification before handoff

    Use the long section and an on-demand pipe and chamber clash check to review cover, bends, and potential hard or soft conflicts before issuing geometry downstream.

  • Live design review

    Open a shared browser model with a client or project team to review a corridor, section, or clash in the same session instead of relying only on a static drawing.

  • BIM and CAD handoff

    Send the coordinated civil model into a Revit project through the add-in, or provide IFC and DXF outputs for downstream BIM and CAD workflows when the account has export access.

Pros and Cons

Pros

  • No desktop installation, licence server, or Civil 3D seat is required to start designing in the browser.
  • Roads, drainage, utilities, public lighting, long sections, and clash review are handled in one model.
  • Native Revit geometry plus IFC and DXF export supports handoff to established BIM and CAD workflows.
  • Live browser links can be shared for colleagues or clients to review the same model during a session.

Cons

  • It does not replace every Civil 3D module and does not run EPA SWMM or catchment analysis.
  • The demo and unpaid accounts cannot export; export is available with a Pro licence, but public pricing and plan limits are not established in the supplied sources.
  • The source describes browser access and a normal laptop workflow, but does not document specific browser, device, model-size, or collaboration limits.

FAQ

How do I get started with InfraGrid 3D?

Yes. The live demo is available in a browser with no installation or signup. The site describes it as suitable for opening on a normal laptop, although specific browser and device requirements are not provided.

What file types can InfraGrid 3D import?

The product can import IFC 2x3, IFC 4, IFC 4.3, DXF, LAS/LAZ, PDF underlays, and GPR survey lines according to the product FAQ. The source also states that large IFC and CAD models can stream in for navigation without loading the whole file at once.

Can I design roads and junctions?

The product supports road and junction work including kerbs, construction build-up, camber, UK markings and signs, junctions, lay-bys, and widenings. Editing an alignment updates the corridor model.

How does clash detection work?

Clash detection is available for pipes and chambers, including hard and soft clashes, but it is on-demand rather than continuously automatic. The engineer turns it on when needed.

What outputs does InfraGrid 3D provide?

A Revit add-in can push native DirectShape geometry to project coordinates, including roads, kerbs, utilities, chambers, and lighting. The site also lists IFC and DXF export. Export is restricted to Pro licences; the demo and unpaid accounts cannot export.
