AI for real construction problems

The construction AI that does not guess the number you sign for

KANDO AI stops construction’s most expensive mistakes — wrong quantities, wrong sizing, clashing designs — before they cost money. Every number comes with its source, formula and unit.

The construction problem

Construction is barely digital — and today’s AI can’t be trusted

AI isn’t what’s missing. The problem is that today’s AI can’t be used where a mistake costs money or safety.

In plain terms

The journey of one wrong number on a building site

A wrong unit on a drawing travels all the way to site: wrong order, delay, rework. Most errors are born on paper — that’s where they must be stopped.

  • 48 % of rework comes from incomplete project data and poor communication
  • Professionals spend 35 % of their time on non-productive work
  • Today's general AI is wrong with the same confidence as when it is right

01

A market with no effective solution

10.8 %

That’s how many EU construction firms use AI. In Romania only 5.2 % — last in the EU.

Details

Only 10.8 % of EU construction enterprises with at least 10 employees used AI technologies in 2025, against an economy-wide average of 20 %. Romania comes last at 5.2 %. The cause is structural: the average EU construction enterprise has 3 people — no budget and no staff for enterprise software rollouts.

Eurostat, reference year 2025

02

Avoidable error is the rule, not the exception

48 %

Almost half of all rework comes from incomplete data and poor communication — it’s avoidable.

Details

48 % of rework is caused by poor project data and poor communication. 30 % of respondents say more than half of their project data is inaccurate, out of date, inaccessible or entered twice, and professionals spend 35 % of their time — over 14 hours a week — on non-productive activity. Construction labour productivity has grown by 1 % a year over two decades, against 2.8 % across the economy.

03

Today's AI does not communicate its uncertainty

98 %?

Today’s AI is just as confident when it’s wrong — and never says which 2 % is wrong.

Details

Generic language models are wrong with exactly the same confidence with which they are right. In a law office the consequence is a bad citation. In a bill of quantities it is a financial loss. In a cable-sizing or heat-load calculation it is a safety problem. Commercial vendors claim 98 % accuracy without independent benchmarks — without saying which 2 % is wrong.

If a tool won’t tell you which number is wrong, the risk belongs to whoever signs. KANDO AI reverses that.

Six everyday problems — and how KANDO AI answers them

M8b · M4

ProblemTakeoff and estimating take days, by hand, from drawings — and one mistyped unit runs through the whole bid.

KANDO AIAI-assisted takeoff from PDF/DWG/IFC, with server-side recalculation and a check on every line item.

M4

ProblemCable cross-section, voltage drop, heat load: a wrong sizing is a safety risk.

KANDO AIThe number comes from an engine working with the formulas of the standards; the independent verifier blocks a wrong one.

M3

ProblemSeveral amended versions of the same code are in circulation, and it is unclear which one applies.

KANDO AIA knowledge graph that names the version and clause applied, and flags contradictions with both sources.

M5 · M4

ProblemClashes between architectural, electrical and HVAC designs surface only on site — as rework.

KANDO AIMore than 200 cross-trade rules on the IFC model, with BCF issues sent to the designer before construction.

M6 · M7

ProblemSite managers estimate progress from photos; payment certificates can be disputed.

KANDO AIRobotic or phone capture aligned with the BIM model, with a per-element status and evidence.

M9 · API

ProblemDistributors take days to produce technical quotes while the installer waits.

KANDO AIVerified calculation built into the distributor's own ERP and web shop through an API.

The solution: verifiable AI

The model understands. The engine calculates. The verifier decides.

Three roles, strictly separated: framing, calculating, verifying. The language model never writes a number.

Where a number can be calculated exactly, the language model does not estimate. If verification fails, the user gets a warning — not a wrong answer.

In plain terms

It works like a careful design engineer

The language model only understands the question. The engine produces the number with the standards’ formulas, and an independent verifier recalculates it — if it doesn’t match, it is stopped.

  • The language model never writes a number into an estimate
  • Every value shows its source, page and formula
  • A wrong result is blocked, not hidden
LLM The orchestrator M4 The verifier API / APP Verified 16 mm² 42,6 kW 1 284 ? Rejected
01

The question

In Romanian, Hungarian or English — from the app, API or MCP.

02

The orchestrator

Breaks the task into steps and picks the right tool.

03

The knowledge

Standards, drawings, BIM and business data — with sources.

04

The deterministic engine

120+ calculation families produce the number. The language model, never.

05

The verifier

Unit, formula, range, recalculation. Wrong? It stops.

Every step goes into a tamper-evident log: question, sources, calculation, check, answer.

Independent deterministic verifier

A wrong result never gets out: only a verified number passes the gate.

Details

Separately from the calculation engine it checks the inputs, the formula, the unit, the order of operations and the consistency of the result. The novelty is not the checking but the blocking architecture: a result becomes an answer only after passing the gate, and a verification failure is itself information delivered to the user.

Provenance at the level of the individual value

Every value carries its document, page, formula and unit.

Details

Every quantity, price or sizing carries its source document, page, formula and unit in an exportable, auditable basis-of-estimate report — exactly what the person signing off a payment application needs.

Knowledge graph that reconciles conflicting standards

When a standard exists in several versions, it says which one it applied — and flags conflicts.

Details

The Romanian electrical and heating standards were both amended in 2023, so different versions of the same text circulate simultaneously. A generic model answers from either one. KANDO AI names the version and the clause applied, and unresolved conflicts are reported as such, with both sources.

Declared limits of observability

What the camera can’t see is never marked as built — it is labelled “not verifiable”.

Details

The distinction between not built and not observable — two situations with identical visual evidence and opposite consequences. An unobserved area is never reported as complete. This property is not publicly documented in any of the progress-monitoring products we reviewed.

In practice

How KANDO AI solves four everyday construction situations

Pick a role and follow, step by step, what happens from the drawing to a document you can sign. Playback is automatic; you can click any step.

TodayTo bid on an office building, walls, openings and cable trays must be measured by hand from dozens of drawing sheets. It takes days, and one mistyped unit runs through the whole estimate.

ResultTarget: half the takeoff time on the same drawings, and an estimate where every line item is traceable.

KANDO AI · Contractor

  • 412 walls · 96 openings · 1,840 m cable tray
  • Plasterboard 1,284 m² ✓ · item 14: m ≠ m² → blocked
  • 214 items · RFQ sent to 6 suppliers

TodayTrade designs are made in different programs. Whether the duct fits under the beam, or a cable meets the amended code, is often discovered only on site.

ResultThe clash is found on screen, not on the slab — and every issue points to the exact clause of the code.

Software architecture

Four layers — the language model never touches the number

Every component is proven technology. What’s new is the order: an answer can only leave through the verifier.

In plain terms

What happens behind a single question?

A cable-sizing question passes four layers: interface → intelligence (model, engine, verifier) → data (standard, project) → integration (back into the company’s systems).

  • Customer data stays in the region, on our own infrastructure
  • Every step is logged and can be traced later
  • Scales by adding nodes, without redesign
InterfaceIntelligenceDataIntegrationLanguage modelEngine + verifierQuestionVerified answer

Interface layer

Where users and other software connect: web, mobile, API, MCP.

  • Web app
  • iOS / Android
  • REST OpenAPI 3.1
  • HMAC webhooks
  • MCP
Details

The web and mobile application, the versioned REST API, signed webhooks and the MCP server through which third-party software agents consume KANDO tools.

Intelligence layer

Where the answer is made and checked: model, knowledge, engine, vision.

  • M2 serving
  • M3 knowledge
  • M4 calc + verify
  • M7 CV state
  • M8b drawings
Details

Domain model serving, knowledge with provenance, the deterministic engine with its verifier, and computer vision for site state and drawings.

Data layer

Separated, protected data for each customer, with an audit log.

  • PostgreSQL 17
  • pgvector + Apache AGE
  • Qdrant
  • S3 storage (SeaweedFS)
  • Keycloak + OpenFGA
Details

Isolated per-tenant databases with vectors and graph in one system, object storage for large files and an append-only audit log.

Integration layer

BIM, robot and business systems — joined by reliable messaging.

  • IfcOpenShell / web-ifc
  • ROS 2 Jazzy
  • NATS JetStream
  • e-invoicing
  • ERP · CSV · BMEcat
Details

BIM/CAD, site capture and business connectors, with idempotent asynchronous messaging between modules.

What the architecture guarantees

Data sovereignty

Customer data stays in the region, on our own servers — not in a foreign cloud.

Details

The adapted model runs on our own infrastructure, in-region. A real requirement for public infrastructure projects, met by none of the international products we reviewed — all of them vendor-cloud services.

Indirect prompt-injection defence

A malicious instruction hidden in a document never reaches the model.

Details

Content from documents and customer data is isolated and sanitised before it reaches the context; the product catalogue is kept out of the prompt and accessed through a tool. Already implemented in the internal prototype.

Server-side geometric recomputation

Quantities are recomputed on the server from raw points — the interface isn’t trusted.

Details

Quantities are never taken from the interface: the server recomputes lengths and areas from raw points and the calibration scale, with bounds validation.

Hybrid inference routing

Simple questions go to the small model, complex ones to the GPU — predictable cost.

Details

Simple queries go to the edge model, complex ones to the GPU, with a quality guarantee — predictable operating cost as usage grows.

Incremental scaling

More users? Add a node — no redesign.

Details

Additional nodes and GPUs without re-architecting, thanks to stateless containerised services.

In plain terms

Why does a building site need a robot?

A robot or a LiDAR phone walks the same route every week and reports, element by element: built, not built, or not visible.

  • Repeatable, dated evidence for every room
  • Handles stairs and unfinished slabs
  • An unseen element is never marked as built
KANDO Capture Verified Unobserved

Bipedal humanoid robot

Climbs stairs, opens doors — walks the same route every week.

Details

~180 cm, climbs stairs (riser ≤18 cm), ≥2 h per battery, ≥2,000 TOPS on-board compute, dexterous hands ≥16 DoF with tactile sensors, ROS 2-compatible SDK, wireless E-stop, CE

Role A research instrument for repeatable capture and for operating doors, hatches and switches along the route. After the project it becomes the physical node of the inspection service.

Details

360°×≥59° LiDAR, ≥40 m at 10 % reflectivity, ≥200,000 pts/s, IMU, PTP sync, IP67; 360° camera ≥8K photo / 5.7K video; recording computer with 32 GB RAM and 2 TB NVMe

Role Produces the point cloud and imagery aligned to the BIM model. Mounted on the robot or carried by an operator in a backpack — identical sensor payload, so the experiments stay comparable.

Dedicated rented GPU

GPU rented in an EU data centre to train the models during development.

Details

1× NVIDIA Hopper/Blackwell class, ≥141 GB HBM, 24/7, inside the European Union, with a data-processing agreement

Role Domain-model adaptation (LoRA/QLoRA), computer-vision training and pilot serving for the whole duration of the project.

Multi-GPU burst compute

Short, high-power runs to generate training data.

Details

8× H200/B200 nodes with NVLink, on demand, approximately 6,300 GPU-hours

Role Runs the 671-billion-parameter teacher model to generate distillation data, ablations and benchmark runs. It is not a serving model.

Production GPU server

Our own production server, replacing the rented GPU from month 22.

Details

2× professional 96 GB GPUs (≥192 GB VRAM total), 2× server CPU, ≥256 GB RAM, 2× 4 TB NVMe RAID-1, redundant power, rack colocation

Role Serves the domain model and the computer-vision models in production and replaces the rented GPU from month 22 — the condition for predictable cost during the sustainability period.

Integration node

Connectors for invoicing, e-Factura and ERP — kept apart from the data.

Details

Mac mini M-series, 32 GB, 1 TB, 10 GbE

Role Runs the connectors to customer systems (invoicing, e-invoicing, ERP, e-mail) and service billing, isolated from the database to reduce the attack surface.

Data and services node

Databases and the small model — fast answers from memory.

Details

Mac mini M-series, 64 GB, 2 TB, 10 GbE

Role Vector and graph databases, the edge model and the platform's containerised services. The 64 GB are needed for the edge model plus in-memory databases.

Local storage and backup

≈40 TB for point clouds and drawings — enough for 24+ months.

Details

Mac mini + 4-bay DAS, 4×20 TB CMR, RAID-6 (≈40 TB usable), Thunderbolt

Role Point clouds, imagery and drawings. A single LiDAR mission produces 5–30 GB; capacity covers more than 24 months of operation.

Network security

Firewall, segmented network, UPS — zero-trust protection.

Details

Firewall ≥2 Gbps with IDS/IPS and ≥1 Gbps VPN, managed switch ≥8×10 GbE, 1,500 VA pure sine UPS

Role VLAN segmentation (production / management / backup), encrypted tunnel access and power-failure protection — the precondition for the zero-trust model.

Off-site backup

An encrypted third copy in another location — the 3-2-1 rule.

Details

100 TB, perpetual licences, client-side encryption before upload

Role The third copy in the 3-2-1 rule, physically separated from the active data.

Site connectivity

No internet on site: a 5G router and mesh Wi-Fi provide it.

Details

Dual-SIM 5G SA/NSA router with VPN, IP67 PoE mesh Wi-Fi 6 access point, ≥500 Wh power station

Role Building sites have no network: this provides the uplink for the robot and the capture kit and resumable synchronisation of large files.

Professional book scanner

Digitising the Romanian and Hungarian technical library — formulas included.

Details

A3+, 600 dpi, V-cradle, ≤1 s per scan, hot folder; text OCR and mathematical OCR for formulas

Role Digitises the Romanian and Hungarian technical library — the proprietary corpus is the differentiator that cannot be obtained by scraping the internet.

Development workstations and test devices

Development and testing on every class of phone, rugged ones included.

Details

6× M-series laptops with ≥48 GB + 12 4K monitors; a LiDAR-equipped iPhone and 3 Android phones (flagship, mid-range, IP68 rugged)

Role Development, local inference for testing and validation of mobile capture across every device class — the scalable capture channel.

Why not cloud only? GDPR and sovereignty, predictable cost, and scaling without redesign.

The team

9 specialists: AI developers and chartered engineers

Six full-time, three sector engineers with 15–21 years of experience. Identities are available during due diligence.

In plain terms

Engineers and AI developers in one team

Construction AI often fails because developers don’t know the site. Here, the sector engineers write the rules and lead the pilots.

  • 15–21 years of professional experience among the domain experts
  • They annotate the domain question-and-answer set
  • Every pilot is led by a domain engineer

The Q&A set annotated by our sector engineers doesn’t exist online — it is the hardest asset to copy.

Why it is hard to copy

What can’t be copied quickly

These barriers are built with time and access, not money.

In plain terms

What protects the investment?

Anyone can plug in a generic AI. A proprietary technical corpus, engineer annotations, a blocking architecture and real-site robotic experience can’t be bought.

  • A proprietary dataset that does not exist on the internet
  • An architecture that cannot be bolted onto a chatbot later
  • A published benchmark the market uses to measure the category

01

A proprietary corpus that does not exist online

Romanian and Hungarian technical library plus engineer annotations — not online anywhere.

Details

The Romanian and Hungarian technical library digitised with a professional scanner and mathematical OCR, plus the question-and-answer set annotated by chartered engineers with 15–21 years of experience. An international competitor cannot collect it.

02

A blocking architecture, not just a checking one

The verifier is the system’s foundation from day one — it can’t be bolted onto a chatbot.

Details

An independent verifier that refuses to deliver a non-conforming result is an architectural decision taken from the outset. It cannot be bolted onto a system in which the language model produces the number.

03

The standards reconciliation graph

Standard versions and their relationships in a graph — extendable to any country.

Details

Clauses as typed nodes with amends, repeals, derogates and applies-to relations, plus temporal validity. Applicable to any language and any body of standards — and therefore to the next markets.

04

Humanoid mobility on a real building site

Stairs, unfinished floors, doors — wherever people walk, the robot goes too.

Details

Stairs, unfinished floors, doors and hatches — the same routes people take. Existing solutions capture reality with rovers or scanners at fixed waypoints, but do not couple it with a layer of verified engineering knowledge.

05

Our own benchmark, published

We publish the category’s benchmark — and lead it.

Details

Over 2,000 items with contamination-resistant parametric generators, released as a public set under an open licence with a DOI. Publishing it creates the standard by which the category is measured — and we lead it.

06

Distribution through other people's systems

Distributors and software vendors resell it through their own systems.

Details

An open API with provenance plus OEM licensing: distributors and software vendors resell the capability through their own ERPs and online shops, which lifts the ceiling imposed by a small sales team.

Why this project

A 24-month R&D programme — measurable results at every milestone

We don’t ask for trust; we give criteria: 10 hypotheses with measurable targets, 6 milestones, a public benchmark.

In plain terms

Step by step: from research to scale

Risk falls step by step: first the lab proves it, then real pilots, then paying customers — every step with a measurable target.

  • Ten research hypotheses, each with a measurable target and a fallback
  • Intellectual property stays entirely with the company
  • A detailed technical and financial dossier under NDA

What makes the project solid

The technology risk is declared, not hidden

We write down what could fail and the plan B — no promises without a benchmark.

Details

Ten research hypotheses, each with what can fail technically, what happens if the target is missed and what the mitigation is. We do not promise accuracy without an independent benchmark.

The core is already demonstrated

Our internal prototype already works: recomputation, auditable formulas, protection.

Details

An internal prototype, built with our own resources before submission, already implements server-side deterministic recomputation, assembly recipes with auditable formula strings, a tool-calling agent and prompt-injection defence.

Intellectual property stays entirely with the company

All proprietary components belong to the company, on an open-source base.

Details

The orchestrator, the calculation engine, the verifier, the model adapters, the corpus and the datasets belong to the beneficiary; the open-source base is under permissive licences.

Compliance designed in from the start

Classified under the EU AI Act; customer data stays in the EEA.

Details

Explicit classification against Regulation (EU) 2024/1689 on artificial intelligence, a data-rights register for every source, and customer data that never leaves the European Economic Area.

Real accessibility, not a declaration

WCAG 2.2 AA and voice control in safety gloves — what matters on site.

Details

WCAG 2.2 AA and EN 301 549, full keyboard navigation, a voice interface in Romanian and Hungarian usable with occupied hands and protective equipment — the real condition of use on site.

Results are disseminated

Public benchmark, open API, papers — negative results included.

Details

A public benchmark under an open licence with a DOI, an open API specification, conference papers and an open-access article — including negative results.

The full technical dossier (architecture, research protocol, specifications, implementation plan) is available to investors and partners under a non-disclosure agreement.
