Figures come from the project close in June 2026. They compare Baltimir's previous manual estimate drafting with the AI workflow set up in two working sessions. A human still reviews every draft before it is sent.
The Context
Baltimir Group is an Estonian construction company preparing detailed building-services (KVVK) estimates for water supply, sewerage, heating, ventilation, underfloor heating and related work. Each project arrives with PDFs, DWG drawings, specifications and an Excel workbook, so the sources and workbook rows have to stay traceable.
The Problem
Every estimate repeated the same expert logic.
The work followed a clear pattern, but the rules lived in the estimator's head and had to be reapplied project by project.
A generic AI chat was not reliable enough.
It could summarize documents, but it could also produce unsupported quantities, miss practical work rows or hide uncertainty inside a total.
The bottleneck was expert time.
Several hours went into preparing a draft before the real commercial review could start.
An AI workspace for KVVK estimates
In two working sessions, we turned Baltimir's estimating logic into a reusable AI workspace (built on OpenAI Codex): templates, rules, reference examples, source-to-row mapping, drawing checks and review gates.
What we built
Set up a repeatable project folder for every new estimate.
Documented KVVK-specific rules so the AI follows Baltimir's estimating logic.
Added source-to-workbook and drawing checks before Excel is edited.
Added a clear review status: ready for review, draft only or blocked.
How it works
AI-ready project folder
Baltimir rule library and price notes
KV/VK/SG discipline split workflow
Drawing extraction and estimate audit scripts
Start instruction for each new estimate
The Impact
About 95% of each draft is prepared by AI.
The AI prepares the estimate draft and separates the points that need human review.
A draft run now takes about 30 minutes.
The estimator starts from the prepared workspace, the AI prepares a marked draft, and the human review stays explicit.
At least 6 hours saved per week.
The value comes from one focused setup that repeats on every future estimate.
