Estimate GESN Rate 2026: how to apply without errors
Creating an estimate using GESN and spending 4 hours searching for rates, recalculating measurement units (100 m2 → 15 m2), and filling Excel? Every error in coefficient = recalculating the entire estimate. In 2026, an AI bot applies GESN rates automatically — finds code, recalculates units, generates estimate.
Key Takeaways
- GESN-2020 — elemental estimate standards for resource calculation method
- One GESN rate contains: labor costs, materials, machinery (separately!)
- Manual rate application takes 15-30 minutes (code search + unit conversion + filling)
- Common errors: incorrect conversion coefficient, forgot to include materials
- AI bot applies rate in 30 seconds — from work description to finished estimate line
Comparison of Methods: how to apply GESN rate in estimate?
| Method | What is it | Pros | Cons | Price |
|---|---|---|---|---|
| Manually in Excel | Reference book search + calculations | Free, full control | Slow (15-30 min per item), calculation error risk | Free |
| Grand Smeta | Professional software | Built-in GESN database, automatic calculations | Complex interface, expensive, training required | from 50 000 ₽/year |
| Resource calculators | Online calculation services | Simplified interface | Limited database, no auto rate selection | from 5 000 ₽/month |
| TimeMaterial AI | AI bot in Telegram + Excel | Rate selection by description, auto unit conversion, export to your template | Currently only GESN-2020 | 5 000 ₽/month |
How to apply GESN rate in estimate in 3 steps?
Instead of 30 minutes of manual search and calculations — describe the work in plain words and get a finished estimate line.
Step 1. Describe work in Telegram bot
Open @timematerial_bot and write: - "Improved wall plastering 15 m2" - "Armstrong ceiling installation 42 m2" - "Partition brickwork 8 m3"
AI automatically determines: - Which GESN rate fits (e.g., GESN15-01-015) - Measurement unit in reference (100 m2) - Labor costs per base unit (3.8 man/hour)
Step 2. Confirm rate and specify volume
Bot suggests 2-3 rate options with breakdown:
GESN15-01-015 — Improved plastering
Labor costs: 3.8 man/hour per 100 m2
Materials:
- Cement mortar: 14.2 m3
- Plaster mesh: 105 m2
Machinery:
- Mortar pump: 1.2 mach/hour
Measurement unit: 100 m2
You specify actual volume (15 m2), bot automatically applies 0.15 coefficient.
Step 3. Get finished estimate in Excel
System generates estimate according to your template with automatic calculation:
- Labor costs: (15 / 100) × 3.8 = 0.57 man/hour
- Materials: mortar (15 / 100) × 14.2 = 2.13 m3
- Machinery: mortar pump (15 / 100) × 1.2 = 0.18 mach/hour
Estimate is exported to your Excel template with formulas and ready to send to customer.

Frequently Asked Questions
What is the difference between GESN and FER?
GESN — elemental standards (separate labor costs, materials, machinery). FER — unit rates (already with prices, ready to apply). GESN is used for resource method with current prices, FER — for base-index method.
How to recalculate measurement units in GESN?
If GESN standard is per 100 m2 and you have 15 m2 — divide 15 by 100, get 0.15 coefficient. Multiply all indicators by it: labor costs, materials, machinery. TimeMaterial does this automatically.
Can I use my own rates instead of GESN?
Yes, in "Professional" plan you can upload your company's own rate reference books — local standards, company databases.
How often is GESN database updated?
Official GESN updates are released quarterly. TimeMaterial loads current versions automatically, you don't need to download anything.
Stop spending 4 hours creating one estimate manually.
TimeMaterial applies GESN rates automatically in 2026 — from work description to finished estimate in Excel in 30 minutes.
Two payment options: - 5 000 ₽/month — subscription, GESN database access + estimate automation - 30 000 ₽ — one-time payment, 1-year access + all updates
