Don't imagine the home.
Step inside it.
From the BIM model to the Digital Twin. TERRAQ turns a development still under construction into a real experience — linking every element to its material, quantity and cost.
The model comes in.
An IFC / openBIM file is loaded. Elements, properties and quantities extracted automatically.
The commercial surface
See → Change → Price → Approve
3D is the interface, not the product. Behind every choice there is a real quantity, taken from the model, and a calculated price — no spreadsheet, no measuring error.
Universal Web 3D
One link opens the project in the browser, no hardware. Maximum distribution through embed.
Cost-linked configurator
4 flawless decisions. Each material applies a price delta coming from the IFC.
VR-ready
The WebXR door stays open at near-zero cost. Premium when there is proven demand.
One architecture, three views
From IFC to Digital Twin
Two paths start from the same model — one of data (ours, automatic) and one visual (commissioned) — and reunite in a table linking every element to its material, option and cost.
Single entry point
IFC, DWG and PDFs come in, are versioned and processed in a queue.
Elements + quantities
Automatic extraction of properties, quantities and hierarchy. This is what scales.
The core technical asset
Links element → material → option → budget line. This is what makes it all work.
Core (Digital Twin) — projects, units, elements, materials, options, costs, documents and leads. Read by the three surfaces: public, professional and Intelligence.
Multitenant · access levels
The same project, each their own view
Developer, builder, architect, agent and buyer access the same Digital Twin with different permissions. Isolation between organisations is enforced by the database engine (Row-Level Security), not by code discipline.
TERRAQ Admin
TERRAQ team. Full access to all modules and tenants.
Developer
Development owner (e.g. Zé / Velmarne). Manages projects, configurator, documents, intelligence and leads.
Builder
Construction company. Sees the project, documents, budget/intelligence and procurement.
Architect
Architecture studio. Access to the BIM model / Digital Twin and project documentation.
Real estate agent
Agency. Presents developments (Explore/VR) and manages leads.
Buyer
End client. Configures their unit and sees their choices and documents.
TERRAQ Intelligence
Reliable numbers. Always sourced.
Proposal comparison, consistency checks and the cross-check between model and budget. All arithmetic is deterministic — the model interprets and explains, it never calculates.
- Proposal comparison normalised by chapter
- Checks: totals, duplicates, units, omissions
- IFC ↔ budget: “the model has 623 m² of façade, the budget measures 480 m²”
- Ask TERRAQ with mandatory line/page citation
▸ Façade: model 623 m² vs. budget 480 m² — 143 m² deviation. [budget p.12, l.44]
▸ Chapter 07 (waterproofing) missing in proposal B. [prop. B]
▸ Duplicate item: concrete C25/30 in 03.2 and 05.1. [budget l.61, l.98]
