The PRALEX ecosystem

Open platform for construction robots and machinery.

PRALEX connects BIM planning with robot-assisted execution on the construction site — through an open data format, a coordination layer and a modular robot platform.

Why PRALEX

The problem

Construction in the DACH region is automating — but without a shared foundation, that automation fragments. PRALEX starts there.

Labour market

Skills shortage & cost pressure

Construction is short of skilled workers, and the pressure grows every year. Automation is becoming a necessity — not a luxury.

Standardisation

Avoiding a format zoo

Today every robot manufacturer builds its own interface to BIM. Without a common standard, dozens of incompatible island solutions pile up over the years.

Access

The hardware & certification hurdle

Anyone wanting to automate a construction process must first develop a safe mobile platform — a six-figure effort. Many sensible applications are therefore never built.

Ecosystem

The four building blocks of PRALEX

Instead of every manufacturer reinventing format, protocol and platform, we propose a shared foundation.

Robotic Construction Format

Open data format

An open format for work orders in construction robotics — as an extension of IFC. Compatible with any BIM tool that exports IFC.

Draft v0.1 in progress

PRALEX Link

Coordination server

Infrastructure for the construction site (cloud + on-site): distributes tasks, tracks status and coordinates several robots — built on ROS2.

In development

PRALEX Chassis

Modular platform

A mobile platform with a shared navigation module (3D LIDAR, laser distance sensor, AI camera), power and safety architecture. Third parties mount their tools via standardised interfaces.

Robots

Three robots, one platform

Different tasks on the construction site — built on the same idea. The marking robot is the current demonstrator; the others show where PRALEX is headed.

Current status

What exists today

Design study of the PRALEX marking robot — aluminium chassis on all-terrain wheels, pan-tilt module with a green marking laser, LIDAR, camera and emergency stop. Concept visualisation, not a photo of an available product. More about the robot →

Robot 2 — marking robot

Our current demonstrator: transfers positions from the BIM model as physical markings onto the construction site — built on an Ackermann chassis. The flagship that shows what PRALEX makes possible.

More about the robot

Robot 3 — follow-me robot planned

A second prototype on a different platform — proof that PRALEX works independently of any single robot.

  1. Now Concept demo End to end: BIM → RCF → robot → marking.
  2. Next Pilot First pilot projects and partnerships.
  3. Later Product Step by step toward a full platform.

Open & IFC-compatible

Complement, don't compete

The Robotic Construction Format (.rcf) is designed as an open standard — not proprietary. It extends IFC via property sets (e.g. Pset_RcfArbeit) and complements existing standards rather than competing with them.

This direction follows the philosophy of buildingSMART. Anyone already working with IFC should be able to adopt RCF without friction.

About

Who's behind it

PRALEX is being built in Germany, focused on construction in the DACH region.

Currently a one-person, self-funded project in an early concept phase — drawing on experience in BIM/Revit and robotics. We build step by step and communicate openly about where we stand.
