Construction AI systems, with the evidence visible.

AnalyzTech

Historical work led by Hugo Sequier before State Method · Client: BTP Consultants

Problem

Manual review covered documents of more than 40 pages and plan-based checks.

System

An R&D-to-production platform combined backend APIs, OCR and computer vision pipelines, polygon visualization, verification skills and AWS deployment. Hugo delivered the work as a solo developer.

Source-reported result

The canonical source reports 80% time saved on verification workflows, a 50% productivity gain, 99% classification precision and 96% room-mask precision.

State Method relevance

Interpretation sits beside structured geometry, application state and a verification interface. The model output is therefore described as one part of operational software, not as a standalone decision.

Floorplan Automation Pipeline

Historical work led by Hugo Sequier before State Method · Client: BTP Consultants

Problem

Technical controllers manually selected plan areas and ran geometric checks one by one.

System

The pipeline took in PDFs, extracted polygons, post-processed geometry, enriched metadata, ran rule-based PMR and fire-safety checks, and generated a report.

Source-reported result

The canonical source reports a 30% productivity increase, 90,000 hours saved and approximately €2 million in economic gains in the project context.

State Method relevance

Deterministic PMR and fire-safety checks hold a different role from plan extraction. The resulting report supports technical controllers rather than replacing their role.

Video to Report

Historical work led by Hugo Sequier before State Method · Client: BTP Consultants

Problem

Site teams took notes during visits and drafted compliance reports later from scratch.

System

The system accepted video uploads, segmented them, used vision-language analysis, extracted key moments and screenshots, and prepared a structured report draft for office review. Hugo built and operated it as a solo engineer.

Source-reported result

The canonical source reports more than 300 hours of video analyzed and approximately three hours saved on report drafting per project.

State Method relevance

A model interprets unstructured video and the software structures supporting evidence. A person reviews the draft in the office before it can serve as a report.

Floorplan Computer Vision

Historical work led by Hugo Sequier before State Method · Client: BTP Consultants

Problem

Very high-resolution floorplans required polygon masks precise enough for downstream checks.

System

Plan ingestion, Roboflow annotation, dataset building, model selection, training and inference deployment. The project also informed a later wall-based room extraction approach.

Source-reported result

The source reports 88 mAP@50 for furniture detection and 60 mAP@75 for room detection. Room masks were not accurate enough for production-grade use.

State Method relevance

The negative finding is part of the evidence: a model score did not override the downstream quality requirement.

Public construction Diagnostic

Fictional company and operating baseline

Evidence label: Synthetic documents and cases · Actually executed workflow and harness · Not a client outcome · Not production evidence · Productivity and ROI remain hypotheses

Problem

Show how one drawing-revision workflow can be bounded and tested before a pilot without presenting confidential client material.

System

A frozen 56-case harness covering representative, edge, known-bad, permission and recovery scenarios, with deterministic controls, human approval and audit records.

Source-reported result

The recorded synthetic run produced 56/56 expected behaviors, zero observed critical unsafe states and 5/5 sampled decisions reconstructed. It supported only a four-week bounded pilot.

State Method relevance

The example makes the method, evidence references and authority boundary visible while stating what the sample cannot prove.
