From the first sketch to the last invoice

Design the project in 3D, quote it with real trade calculators — not rules of thumb — run EU-ready energy audits, plan the crew, track the site through a worker portal, and sell materials on the side. One platform for the whole job.

Design and estimate like an engineer, not a guess

Every calculator outputs a real bill of materials, not a ballpark figure.

🏗️

3D project designer & AR

Build an interactive 3D scene of the project and walk through it in AR on site before anything is built.

☀️

Solar, thermal & HVAC

Size a solar installation, run a thermal audit, and calculate heating/cooling loads from real project data.

🧱

Roofing calculator

Computes cover weight by material, adds snow load for your region, and flags when a crane is required — not just a square-metre estimate.

🏠

Insulation & facade

A 2D facade editor, 3D viewer and plate-layout optimiser, with documentation generated alongside the materials list.

🪜

Scaffolding planner

Computes wall-by-wall scaffold geometry and every component — frames, ledgers, decks, anchors — with buy or monthly-rent pricing.

🧾

Blueprint & CAD export

Layered vector drawings with DXF export for AutoCAD and print-ready PDFs at proper scale.

Run the site, not just the drawing

The part that happens after the quote is accepted.

👷

Labor norms & crew planning

An editable table of labor norms by trade and skill level feeds hours and cost into every calculator above.

📱

Worker portal

A no-login, QR-based portal where crews see today’s tasks, submit progress reports with photos, and mark work zones on a map.

🧮

Milestones & materials catalogue

Track project milestones and keep a shared materials catalogue that every calculator draws from.

🛒

Materials webshop

Sell materials directly with a 3D product catalog, quote requests and pricing rules — the same storefront as the rest of Oprela.

🌐

Lead-capture widget

An embeddable widget for your own website that captures project leads straight into your pipeline.

📜

Energy certificates online

Sell energy certificates through your own website: an order wizard with online payment, an ERP queue, signing with a stamp and control hash, and public QR verification for every issued certificate.

Questions from builders and renovators

Do the calculators just give a rough estimate?+
No — roofing accounts for material weight and regional snow load, scaffolding computes every component by wall, and insulation includes a plate-layout optimiser. These produce a real bill of materials.
Can my crew use this without training?+
The worker portal needs no login — a QR code opens today’s tasks, and workers submit progress with photos from their phone.
Can I sell materials, not just estimate them?+
Yes — the same platform includes a materials webshop with a 3D catalog and quote requests.
Can I show a client the project before starting?+
Yes — the 3D designer and AR view let you walk a client through the project on the actual site.
