Construction estimates,
in half the time.
Digging out old quotes and rebuilding them, sorting site photos, chasing subcontractors. We start with the hours that disappear on site every day.
Four problems we hear across constructionProblems
- 01
Every estimate takes one to two days
Find a comparable job, verify unit rates, rebuild the formatting. Only one person can do it, and peak season jams.
- 02
Site photos and reports never get filed
Hundreds of photos come off site. Sorting and linking them is manual, so it piles into month-end overtime.
- 03
Tradespeople's judgement never gets handed down
Construction standards and past incident responses live in veterans' heads, so juniors ask the same questions again and again.
- 04
Subcontractor exchanges stay on phone and fax
Orders and schedule changes leave no record, so disputes over what was said follow.
Three services that move the needle in constructionService
A full menu helps nobody choose. These are the three that pay off first on a construction operation.
Gugen PrototypePoC development
¥1M–3M1–2 months
We ingest your past estimate data and build, within one to two months, a version where entering the conditions produces a draft quote — then check it holds up.

From ¥300,000~1 month
An internal chat grounded in construction standards, past incident responses and company rules absorbs the questions juniors keep asking.

Whether the site keeps using it comes down to operations. We watch how it's used month by month and keep reshaping it.

What handing estimates to AI looks likeHow it works
- STEP 1
Ingest past estimates
We consolidate the jobs scattered across spreadsheets into a form the AI can reference.
- STEP 2
Enter the conditions
Trade, scale, location — enter them and it pulls the closest past jobs as its basis.
- STEP 3
A draft comes out
Line items and quantities arrive filled in. Your estimator concentrates on rates and special conditions.
- STEP 4
Review and confirm
The final call stays with a person. AI only takes over the searching and rebuilding.

What people worry about beforehandFaq
- We have nobody who knows AI.
- That's fine. One team covers planning through operations, and we work without jargon.
- Our historical data isn't organised.
- Unorganised is the norm. During the assessment we judge whether it's usable as-is.
- A large contract up front is hard for us.
- Start with the ¥98,000 assessment. No lock-in period, and you can stop the moment it's clear it isn't working.
