The road and rail sector item catalogues in one program
Under decree 31/2024. (VIII. 22.) ÉKM, the official sector item catalogues become mandatory on Hungarian public construction projects, sector by sector. INKA works with them directly, not with its own norm database, so the item numbers and texts in your bill of quantities are exactly what the client expects.- Road
Road Sector Item Catalogue (KÁT)
e-UT 01.02.11 · updated quarterlyIssued as a road technical regulation, KÁT is the basis of unpriced bills of quantities and priced quotes on road projects. In INKA the whole catalogue is searchable by chapter and item number, and updates bring in the current quarterly version.
- Rail
Rail Sector Item Catalogue

How it works
Four steps to a finished quote
Opening a new project or editing an earlier one
Picking items from the catalogue and entering quantities
Pricing, with saved unit prices filled in automatically
Excel export: generating the priced and unpriced quote
Before and after
The same job, two ways
With spreadsheets
- You look up items by hand in a catalogue thousands of rows long.
- Past unit prices are scattered across files and have to be dug up again for every project.
- When two people work on one estimate, nobody knows which version is the latest.
- When you need an earlier version, you dig through file names and emails.
- The priced and the unpriced bill of quantities have to be put together separately.
With INKA
- Pick items from the tree or by search; the item number and unit come in automatically.
- You save your unit prices, and the software fills them in automatically on the next project, from a shared database.
- You work from one shared database, so items, prices and projects are the same for everyone.
- Built-in versioning: every priced export gets its own version (V1, V2…), so you can always go back to an earlier one.
- One click: the priced and unpriced quote in Excel, a worksheet per chapter.
What it does
Everything a construction cost estimate needs
Unit price, or material + labour
Price each item with a single unit price, or with separate material and labour rates. Anything not in the catalogue can be added as a custom item.
Prices that stay
Saved unit prices are filled in automatically when you add the item again in a later project.
Templates for recurring work
Common item sets can be saved as templates, so a new estimate never starts from a blank sheet.
Teamwork on one database
The database runs on the office server or NAS, so everyone works with the same items, prices and projects.
Versioned Excel and quotes
Priced and unpriced estimates in one click, with a worksheet per chapter. Every priced export is saved as a new version (V1, V2…), earlier ones are kept.
The Excel export
One click, three finished files
A priced export produces the priced estimate, the unpriced bill of quantities and the item descriptions in one go. It writes the Excel formulas too, so the finished file stays easy to edit: change a number and everything recalculates. All three land in Documents / Exportált_Projektek, in a subfolder named after the plan number.Priced estimate

Infrastructure
Everyone works from the same database
INKA is a desktop app: every user runs it on their own computer, while the items, prices and projects live in one shared database. That database runs at your office or, if it suits you better, in the cloud.Office PCs connect over the local network, the home laptop over VPN, all to the same database.
- Local server or NAS
- The shared database runs on the office server or NAS; your data never leaves the office.
- Desktop app on every PC
- INKA runs on each colleague's Windows PC, and they all use the same database: shared items, prices and projects.
- Remote access over VPN
- Anyone working outside the office reaches the same database over VPN, as if they were sitting at their desk.
- Cloud hosting
- No server of your own, or several sites? We can run the database in the cloud instead, on a server in Hungary.

It is a desktop program for Windows 10 or 11. With several users, the shared database runs on the office server, a NAS or in the cloud, and we help you set it up.
The Hungarian Road Sector Item Catalogue (KÁT, e-UT 01.02.11), the Rail Sector Item Catalogue and the Building Sector Item Catalogue, in the current versions published on the government investment portal. Every package includes one catalogue of your choice; the others are available as extras.
KÁT is the Hungarian road technical regulation e-UT 01.02.11: it fixes the cost items of road projects with uniform item numbers and descriptions. Unpriced bills of quantities and priced quotes on public road projects are built on it. MAÚT publishes a new version every quarter, and INKA works with the current one.
According to the government investment portal, the Rail Sector Item Catalogue is mandatory from 4 March 2026. It organises the items of mainline and urban rail (tram, suburban rail, metro) projects. In INKA it is searched, priced and exported to Excel exactly like the road catalogue.
Traditional estimating programs are built on their own norm databases. INKA works directly with the official sector item catalogues, so the item numbers and texts in your bill of quantities are exactly what a public client expects under KÁT or the rail catalogue. No conversion, no manual mapping.
Engineering design firms, cost estimators and contractors who prepare road, rail or building cost estimates and quotes on the official Hungarian sector item catalogues, alone or as a team.
Not by default: the database runs on your own server or NAS, and estimates and unit prices never leave the office. If it suits you better, we can run it in the cloud instead, on a server in Hungary.
In the first year updates come with the package: one new version in the Solo package, every quarterly change in the Team and Enterprise packages. Beyond that, and after the first year, an item catalogue update can be ordered one occasion at a time. New versions of the software come at no extra cost during the support period, and support after the first year is agreed individually.
Yes. We load your existing unit prices in a one-off import, whatever the source, available as an extra with any package.
Working in INKA7
Yes. If, say, a road marking or paving stones appear in several colours on the plan, the item can be added on several rows, with the difference noted in the notes column.
Yes. The search looks in both the item name and the item number, including part of the number.
Yes, with a decimal comma. Quantities are kept to one decimal place and appear that way in Excel too, for example 9,0 or 10,9.
No, you enter the unit prices on your first projects. In the “Save unit prices” window you choose, item by item, which prices to save or overwrite, and the software fills them in automatically on later projects.
Add it as a custom K item with a name, unit and description. It stays in the catalogue for later projects, and in Excel it goes on a separate “Custom items” sheet.
Yes. The plan number, client, location, date, description and pricing mode can all be changed later; the project name is fixed.
Frequently used item sets can be saved as templates and loaded into a new project. The software asks before loading, because a template replaces the items in the table; templates do not store quantities or prices. A template is updated by saving over it under the same name.
Export and versions3
Yes. The unpriced export only needs the quantities; prices are optional. The unpriced bill can also be exported on its own.
To Documents / Exportált_Projektek, in a subfolder named after the plan number. File names carry the plan number, version and date, and the unpriced and item description files get their own suffix.
Every priced export saves a new version, and earlier ones are kept. When you open a project, you choose which version to continue from.
