Create project
An empty project, in your tenant
Create a project from the browser. It starts empty — or import an IFC you already have.
Powered by
Browser-native BIM and ERP for engineering offices
Design the building in the browser. Cost it, share it, hand it over.
CHERT Engineering takes a project from empty to a validated IFC model — walls, openings, curtain walls, roofs, structure, stairs and MEP — then reviews it in 3D and 2D, prices it in Saudi Riyal and hands the quantities to ChertERP. On your own server, in English and Arabic.

Three ways in
One model for everyone who touches the project
The design office builds it. The site and the client read it. The office runs the business on it. One platform carries all three.
I design buildings
Start from an empty project and author the whole building in the browser — architecture, structure and services — with every save regenerated as a validated IFC.
I review on site or as a client
Open the model in 3D on a laptop, tablet or phone, read plans and reports, or follow a read-only share link — no account and no licence needed.
I run the office
Take quantities off the model, price them in SAR, and send them to the matching ChertERP project — linked only after an administrator confirms it.
The project lifecycle
Every building follows the same journey — from an empty project to priced lines in the ERP.
Ten stages, one model. Select a stage to see what happens — and which parts of CHERT Engineering make it work.
Stage 02 / 10
Set out storeys
Levels and elevations
Define the storeys and their elevations. Every element you draw belongs to one of them.

Stage 03 / 10
Author architecture
Walls, openings, facades, roofs
Draw walls at exact dimensions, cut openings, place doors and windows, build curtain walls and pitched roofs, and assign wall build-ups.

Stage 04 / 10
Structure & MEP
Frames, stairs and services
Generate footings, columns and beams, add stairs between levels, and route pipes and ducts with fittings and terminals.

Stage 05 / 10
Copy to all storeys
Author once, replicate
Copy a typical floor's walls, openings, slabs, rooms and furniture to every storey in one action.

Stage 06 / 10
Generate & validate
Your design becomes IFC4
On save, the synthesis engines regenerate the full model — types, property sets, quantities, spaces and connections — and validate it against the IFC schema.

Stage 07 / 10
Review & share
3D, plans and coordination
Walk the model in 3D, read plans per storey, run clash and MEP reports, and send a client a read-only link.

Stage 08 / 10
Plan in 4D
Construction over time
Attach dated tasks to IFC classes and play the building's construction on a timeline.

Stage 09 / 10
Cost & BOQ
Quantities priced in SAR
Take quantities off the model, price them against a rate schedule and export the bill of quantities.

Stage 10 / 10
Hand over to ERP
A confirmed, audited link
Link the model to its ChertERP project after an administrator confirms it, and send the quantities to its project lines.

02
Generate
Synthesis engines turn the design into a complete, connected model.
03
Review & share
Everyone reads the same model — office, site and client.
04
Cost & ERP
Quantities become priced lines in the business system.
P
Platform & trust
Your server, your tenants, every change recorded.
S
Standards & assurance
Open formats in, open formats out, checked every release.

One platform, many engines
Everything an engineering office needs to design, cost and hand over — in the browser
Each engine does one job well. One model and one sign-in carry you across all of them.
BIM authoring in the browser
CHERT Modeller
Walls, openings, doors and windows, storeys, curtain walls, roofs, structure, stairs, MEP routes, rooms, materials and components — from an empty project.
app.chertengineering.comDesign to IFC4
Synthesis engines
Regenerate the full model on every save — storeys, openings, facades, roofs, structure, stairs, MEP, materials, spaces, connections and semantics — then validate it.
Solid 3D, any device
3D viewer
The IFC opens as solid meshes in the browser; click any element for its properties. Works on a phone on site.
Live modelDrawings from the model
2D plans
Per-storey floor plans with grids and tags, generated from the model and exportable as DXF.
Clash · MEP · BOQ
Coordination reports
Clash detection by discipline pair, an MEP bill of quantities and cost charts, shareable as reports.
Construction over time
4D schedule
Dated tasks against IFC classes, played back as the building assembling on a timeline.
Quantities and cost
BOM & costing
Takeoff for every IFC class with the source of each number, priced in SAR against a rate schedule, exported to CSV.

ChertERP
A real ERP with a full Arabic interface — more than 6,000 translated elements — projects, project lines and accounting in Saudi Riyal.
Multi-project hosting
Project host
Tenants, roles, share links, ERP links and an audit trail — every project on one server you control.
Inside the platform
Real screens from the running platform
Not mock-ups: captured from CHERT Engineering during verification.
Proof, not a roadmap
A four-storey hospital, rebuilt from an empty project
We took a real federated hospital model as the target and rebuilt it through the normal engineer workflow — nothing imported, no direct IFC editing — then compared the result element by element.
4 storeys from empty
56 walls, 16 doors, 24 windows, 23 slabs, 20 rooms and the roof, authored in the browser.
396 · 392 · 104
Pipe segments, fittings and terminals, generated from routed MEP runs with real connections.
Full structure
36 columns, 51 beams, 12 footings and 2 stairs across the storeys.
1,233 elements
With 64 furnishings, 16 materials, 14 layer sets and 107 space boundaries.
0 validation errors
The rebuilt model is valid IFC4 against the schema.
0 defects · 0 missing
The strict comparator passed all four reference models, the hospital included.
Why CHERT Engineering
Built so that design, cost and the business stay connected
Your data stays on your server
One server you control holds the models, the projects and the accounts. No third-party model store, nobody between you and your client's drawings.
Arabic is not an afterthought
The ERP ships with a full Arabic interface, the site and guides are bilingual, and accounting is in Saudi Riyal from the first day.
No licence per engineer
Authoring and viewing run in a browser, so adding the tenth person to a project costs nothing. Site staff read the same model on their phones.
Every save is a valid model
The design record stays the source of truth; each save regenerates a consistent IFC4 model and checks it against the schema.
One script, one server
sudo ./install.sh --domain app.example.com --email you@example.com — on a plain Debian or Ubuntu server. Distributed privately with three bilingual guides.
Open underneath
The 3D/BIM runtime is open source under the MIT licence, and ChertERP is a rebranded distribution of iDempiere under the GPL v2 — both used with their copyrights and licences intact.
Your next building starts from an empty project.
