The construction industry's
digital memory

What does a school renovation really cost? The answer doesn't come from estimates, but from projects already built. That is why ELOP gathers the actual costs, settlements and technical outcomes of completed investments — and makes them searchable for everyone working on the next one.

Its task is to process, structure and analyse the data of closed projects, so that the experience of every investment becomes the knowledge base for the ones that follow. From earlier projects the system builds a benchmarkable, comparable, AI-analysable knowledge asset that supports cost estimation, project review, decision-making and investment preparation.

ELOP can serve as a national reference system for reviewing investments and checking their realism. Based on the actual technical, cost, resource and performance data of previously completed projects, it enables objective analysis and comparison of investments.

Reality checking is ELOP's job: the system automatically measures planned projects, incoming bids and — emphatically — the settlements of completed investments too against the actual data, and flags anything that doesn't add up. A closed project is not exempt from scrutiny either: costs deviating from market references, unusual technical solutions, resource-use anomalies and unjustifiably high or low prices are flagged the moment the data arrives. In this way ELOP supports oversight, decision-making, cost estimation and investment transparency.

ELOP contributes to a more transparent construction and public-procurement environment built on objective data and supporting genuine market competition.

Digital mapping
of the building stock

What if, by entering a few street names, you could see all the buildings of a district in 3D within minutes — together with their energy condition? That is exactly what STRAVISION does: from open geospatial data it automatically surveys the building stock of the selected area. The first pilot area — Budapest XV, the zone bounded by Telek utca, Rákosmező utca, Fazekas sor and Aporháza utca — produced its 845 buildings in minutes at the press of a button; further locations have since followed, and the stock keeps growing.

For every building the system produces an energy estimate — good / medium / poor class, annual energy consumption, CO₂ emissions and renovation resource need — and gives an aggregated energy picture of the area. IFC models processed in STRABIM can be fitted as archetypes to the real stock: the renovation of similar buildings can be calculated with the model's itemised, priced data.

Area selection is self-service: it's enough to give the bounding streets, and the import, energy classification and model fitting run automatically. The results are estimates of a unified methodology — not energy certificates — but they are produced in large volume and instantly, so the stock-level picture emerges in minutes rather than days.

STRAVISION thus supports municipalities, state institutions, utilities and investors in the strategic planning of the building stock, the preparation of energy-modernisation programmes and the delivery of decarbonisation goals.

The digital passport
of installed materials

Where did that pallet of bricks go — and what exactly was built into the wall? The Material Tracker always knows the answer: it follows the full journey of construction materials from the order, through on-site receipt and installation, all the way to demolition, when materials can be given a new life.

Every installed product gets a digital material passport containing the STRACODE product identifier, the CE certificate, the EPD and carbon data, and the delivery and installation history. So instead of the elements in the model, it is the materials actually installed that become searchable and auditable.

The full chain of material substitutions is documented: every change is traceable, together with its justification and approval. The system gives a real-time, reliable as-built picture of the building — of what was actually built, not merely what was planned.

The material inventory that emerges is the basis of the circular economy: at demolition it is precisely known which materials, in what quantity and at what quality are available for reuse. The Material Tracker builds on STRACODE's product database and STRABIM's models, so it fits organically into the STRATERA ecosystem.

Handover is not the end —
the switch to operations

The longest — and overall most expensive — phase of a building's life is not construction but operation. STRAFACIL brings here all the knowledge accumulated during construction: after handover, every room, system and piece of equipment starts with the data of the products actually installed, not a blank page.

Onboarding is two-way: if an IFC model exists, the BIM base data comes from it; if not, the building or building complex can be recorded with STRATICA's coding system too — fully valid even without a model. On this backbone the daily processes are built: planned maintenance with the mandatory inspection cycles, mobile fault reporting and work-order handling, warranty tracking from installation data, and monitoring of document expiries.

Energy monitoring closes the loop: the actual consumption of manually recorded or API-connected meters can be compared with STRAVISION's and STRATOX's estimates — so the platform's estimation models are refined from real operational data.

The first target group is institutional operators: schools, offices, healthcare and other public institutions, where statutory inspection obligations, documentation and plannable renovation are everyday tasks. Renovation preparation is supported by COSTRATA's benchmarks and STRAVISION's stock analysis.

access?

The platform's modules are access-restricted. If you don't have an account yet but are curious about the system, request a free demo — 30–45 minutes, online or in person, and we'll show what it can do on your own project. We're also happy to discuss pilot opportunities.
