InfraGrid 3D — Browser Civil & Utility Design
Route. Verify. Export native. Browser-native civil and utility BIM for roads, drainage, utilities and public lighting — with live long sections, on-demand clash, and native Revit / IFC / DXF export.
Model carriageways, kerbs, drainage, duct banks and public lighting to construction detail. Work in the browser — no Civil 3D install — and export the same model to Revit, IFC or DXF.
Set out the road, route the utilities, and check the long section before anything is built. Kerbs, build-up, chambers, cover and bend radii stay in the model.
InfraGrid 3D is browser civil and utility BIM. Civil engineers, BIM managers and utility designers route roads, drainage, utilities and public lighting in a web tab, verify live long sections, run clash when they choose, and export native Revit, IFC and DXF. A Revit plugin and Mapbox site context are included. Nothing to install.
InfraGrid 3D is browser-native: no desktop install, no licence server, no Civil 3D seat to start designing. Live long sections and on-demand clash sit in the same model as the roads and services. Export is native Revit geometry plus IFC and DXF. It does not replace every Civil 3D module, and it does not run EPA SWMM, catchment design, or duct-bank modelling.

Frequently asked questions
What is InfraGrid?
Civil engineering design in the web browser. You model roads, drainage, duct banks, chambers and public lighting, and read the long section from the same model. When the drawing needs to leave, export to Revit, IFC or DXF.
Why not just use Revit or Civil 3D?
Those tools are built for buildings and full highway models. InfraGrid is for the civil work around them: move a road or a service bank, keep the cover and bend radii, and check the long section without rebuilding each pipe.
Does it run in a browser?
Yes. Open a link on a normal laptop. There is no install to start designing. Large IFC and CAD models stream in so you can navigate them without loading the whole file at once.
What can I import and export?
Import IFC (2x3, 4, 4.3), DXF, LAS/LAZ, PDF underlays, and GPR survey lines. With a Pro licence, export native Revit geometry, IFC, DXF, PDF drawings, and CSV take-offs. The demo and unpaid accounts cannot export. GPR crown lines convert to 3D pipes in one step.
Can I design roads and junctions?
Yes. Kerbs, construction build-up, camber, UK markings and signs, junctions, lay-bys and widenings. Edit the alignment and the corridor updates.
How does the Revit export work?
Install the InfraGrid add-in, then push native DirectShape geometry to your project coordinates — roads, kerbs, utilities, chambers, and lighting — without a manual IFC import on every iteration.
Can I share live models with clients?
Yes. Share a browser link on the call — colleagues and clients see the same live model. Move a corridor, read a section, or review a clash in session. Decisions land in the meeting, not in next week's PDF.
Where is my project data stored?
Projects save to managed cloud storage in the browser. Share links for review. Export IFC, DXF, or Revit once you have a Pro licence. You own your data. Extra storage is available as an add-on.

InfraGrid 3D — Drainage design software that models underground services properly
Lay storm and foul networks to fall, place chambers at every vertex, and watch long sections update as you drag inverts — all in a browser tab, with no CAD install and no overnight licence dance.
Browser-native civil and utility BIM for roads, drainage, utilities and public lighting — with live long sections, on-demand clash, and native Revit / IFC / DXF export.
Underground services modelling at LOD 400
Most drainage packages stop at a centreline and a schedule. InfraGrid models the real thing: pipe barrel and wall thickness, bedding and surround, trench excavation, chamber walls, cover slabs and benching. That means the model you coordinate with is the model that gets built, not an abstraction you have to reinterpret on site.
Storm, foul, watermain, ducting and MV/LV all live in the same scene with the same coordinate system, so the clash you would otherwise find during construction shows up while you are still designing.
Gravity networks that respect the rules
Gravity services are laid as straight runs between chambers, with a chamber at every change of direction — the way adopting authorities expect. Default gradients follow common practice (1:100 storm, 1:80 foul) and you can override diameter, material or gradient per segment without rebuilding the run.
Cover depths, backdrop requirements and connection angles are checked as you draw, so a run that would fail an adoption review is flagged immediately rather than at submission.
Long sections and chamber details generated, not drafted
Every run has a live long section. Drag a vertical intersection point and the gradients, invert levels and cover levels update across the drawing set. Chamber elevations detect wall penetrations automatically for all four walls, or produce a developed view for circular chambers.
Export to PDF or DXF at 1:50, 1:100 or 1:200 when you need to issue, and push the coordinated geometry straight into Revit as native families.
Frequently asked questions
Does this replace a hydraulic analysis package?
No — it feeds one. InfraGrid handles the geometric and constructability side of drainage design and exports the network as EPA SWMM nodes and conduits so your hydraulic model uses the same layout you drew.
Can I coordinate drainage against an architect or structural model?
Yes. Import IFC from Revit, ArchiCAD or Plant 3D and run clash detection against your pipe runs and chambers in the same browser session.
What level of detail do the underground services reach?
LOD 400+. Pipes carry real wall thickness, bedding and surround; chambers carry wall construction, cover slabs and located penetrations, which is what makes the quantities usable.
Do I need to install anything?
No. The modeller runs in the browser. The only optional install is the Revit plugin if you want live push and pull with a Revit model.

InfraGrid 3D — Road design software with real construction build-up
Set out alignments, kerb lines, crossfalls and full pavement layers, then take quantities straight off the model. No install, no licence server, and the geometry is detailed enough to build from.
Browser-native civil and utility BIM for roads, drainage, utilities and public lighting — with live long sections, on-demand clash, and native Revit / IFC / DXF export.
LOD 400+ corridors, not extruded ribbons
InfraGrid models individual kerb units with joints, bedding and haunch geometry, plus every construction layer from formation to wearing course. Because the layers are real solids, material take-offs come from the model rather than a spreadsheet estimate.
Crossfalls are entered as ratios the way engineers write them, levels are held as real-world AOD, and superelevation transitions are generated on outer horizontal curves.
Junctions, widenings and priority geometry
Add bus stops, lay-bys, islands and localised widenings by chainage; transitions and tapers are calculated and stitched into the corridor. Edit an alignment and connected junction geometry regenerates down the chain instead of leaving you to patch each intersection by hand.
Raised tables, road surfacing zones and footway variants with flush kerbs are all parametric, so a late comment costs a parameter change rather than a redraw.
Drawings and markings from the same model
Cross sections and long sections are cut from the live model at any chainage, with DXF layer mapping ready for issue. Road markings — centre lines, arrows, hatching, zigzags, stop lines and freeform SVG shapes — are parametric and produce their own quantity take-offs.
Import survey as LAS/LAZ point clouds or CAD, drape the design onto existing ground, and check cut and fill before anything is committed.
Frequently asked questions
Is this a Civil 3D replacement?
For corridor geometry, underground services and the drawings that come off them, it covers the same ground with far less setup — and it runs in a browser. Teams that still need Civil 3D for specific deliverables use InfraGrid alongside it and exchange via IFC, DXF or the Revit plugin.
How are levels handled?
All elevations are real-world AOD relative to the project origin, so survey, drainage inverts and road levels agree without manual offsets.
Can I model roads and drainage together?
Yes — they share one scene and one coordinate system, so gullies, laterals and chambers sit against the actual road surface and clash detection works across disciplines.
What hardware do I need?
A modern browser. The 3D engine runs client-side and works on laptops and tablets, including touch input.

InfraGrid 3D — Public lighting design coordinated with the rest of the corridor
Place columns along a road by chainage, route ducting and cabling back to the feeder pillar, and keep the whole lighting layout in the same model as your drainage and pavement.
Browser-native civil and utility BIM for roads, drainage, utilities and public lighting — with live long sections, on-demand clash, and native Revit / IFC / DXF export.
Columns placed where the road actually is
Lighting columns are positioned by chainage and offset against the road alignment, so a change to the corridor moves the lighting with it. Pole height, arm type, bracket, fixture and wattage are parameters, and four style presets cover the common municipal specifications.
Because the columns sit in the same scene as kerbs, footways and underground services, you can see immediately whether a foundation clashes with a drainage lateral or a duct bank.
Cabling and ducting as modelled geometry
Electrical connections are routed as real conduits between columns and the feeder position, following the same trench rules as other underground services. That gives you duct lengths, draw pit locations and excavation quantities rather than an assumed cable run.
MV/LV corridors, ducting and lighting circuits can be modelled together, with clash detection running across all of them.
Schedules and drawings without redrafting
Column schedules, fixture types and wattage totals come off the model. Layouts export to DXF for issue, and the geometry pushes into Revit as native families for the wider BIM deliverable.
When a specification changes, edit the fixture parameters once and every schedule and drawing follows.
Frequently asked questions
Does this perform photometric calculations?
InfraGrid covers the layout, ducting, schedules and coordination side. Illuminance calculations stay in a dedicated photometric package; the column positions and fixture data you produce here feed it directly.
Can lighting follow a road I have already designed?
Yes. Columns are placed by chainage and side against the alignment, so they stay correct when the corridor geometry is edited.
Are the ducts modelled or just drawn as lines?
Modelled. Conduits use the same trench and bedding geometry as other underground services, which is what makes the quantities and clash results meaningful.
How does this reach a Revit deliverable?
The Revit plugin pushes coordinated geometry in as native families, so the lighting design lands in the federated model rather than as a linked mesh.

InfraGrid 3D — Civil engineering design that lands natively in Revit
If your project is already federated in Revit, the civil package should not arrive as a dead mesh. InfraGrid models roads, drainage and utilities in the browser and pushes them into Revit as native geometry, with two-way sync.
Browser-native civil and utility BIM for roads, drainage, utilities and public lighting — with live long sections, on-demand clash, and native Revit / IFC / DXF export.
InfraGrid 3D is browser-native: no desktop install, no licence server, no Civil 3D seat to start designing. Live long sections and on-demand clash sit in the same model as the roads and services. Export is native Revit geometry plus IFC and DXF. It does not replace every Civil 3D module, and it does not run EPA SWMM, catchment design, or duct-bank modelling.
Why Revit-first teams end up fighting their civil tools
The traditional route is Civil 3D for corridors and services, then an export that Revit treats as reference geometry. Elements are not editable, coordinates drift, and every design change restarts the handover. On data centre, pharma and campus projects — where architecture, structures and MEP already live in Revit — that handover is where the schedule leaks.
InfraGrid attacks the handover rather than the modelling. The civil model is authored against the same coordinate system, then written into Revit as native families that behave like the rest of the model.
Live sync, not a one-way export
The Revit plugin seeds a coordination matrix from the Revit model, then keeps the two in step: push the browser design in, pull Revit changes back out. Coordinates, levels and units are reconciled on the way through, so the road you drew sits where you drew it.
IFC import and export cover the rest of the supply chain — ArchiCAD, Plant 3D and anything else that speaks IFC — with clash detection running in the browser before anything reaches the federated model.
A realistic Civil 3D alternative
InfraGrid is not trying to be every module of a desktop civil suite. It is aimed at the work most infrastructure teams actually repeat: corridors with proper construction build-up, gravity drainage and utility corridors, lighting, long sections, chamber details and quantities.
There is nothing to install for the design work, licences are per user rather than per workstation, and a new engineer is productive the same day — which is usually the deciding factor rather than any single feature.
Frequently asked questions
Do I need Revit to use InfraGrid?
No. The modeller is self-contained in the browser and exports IFC, DXF and PDF. The Revit plugin is only needed if you want native geometry and live sync with a Revit project.
Which Revit versions are supported?
The plugin targets current supported Revit releases. If you are on an older version, IFC exchange still works without the plugin.
How does this compare to Civil 3D?
Civil 3D is broader and desktop-bound. InfraGrid concentrates on corridor, drainage, utility and lighting design with LOD 400+ detail, runs in a browser, and hands off natively to Revit instead of exporting reference geometry.
What happens to coordinates on the way into Revit?
The plugin seeds a coordination matrix from the Revit model and transforms through it, so shared coordinates and real-world levels are preserved in both directions.
