A budget platform connecting models and data.

Open-source BIM platform for engineering and architecture
It is a free, open-source technology platform for intelligent management of engineering and architecture projects, designed to integrate natively with BIM workflows.
Its purpose is to connect the digital model with planning, technical control, and the economic information of the project—bringing unit cost analysis, technical specifications, and operational data into a single ecosystem.
The platform is powered by specialized plugins for Revit and Navisworks, enabling direct interaction with BIM model elements, reading and writing technical parameters, and linking them to centralized and continuously updated databases. This transforms 3D models from graphical representations into active, reliable sources of information for decision-making, activity scheduling, and overall project control.
As a free and open-source solution, the platform allows organizations to audit, extend, and adapt the system to their specific needs. This enables in-house development, integration with existing corporate systems, and deep workflow customization—without relying on closed platforms or restrictive licensing.
The system is ready for enterprise on-premise deployments, allowing organizations to run the platform on their own infrastructure while maintaining full control over data, security, and internal policies. This is especially relevant for entities that require high confidentiality standards, regulatory compliance, or technological independence.
In addition, the platform follows a White Label approach, enabling adoption by different organizations, institutions, or projects with their own identity. Each implementation can be customized in branding, data structure, technical catalogs, and internal rules—while preserving a common technology core that ensures scalability, traceability, and governance.
Overall, the platform acts as a bridge between BIM modeling, technical management, planning, and data—integrating tools, processes, and knowledge into a single, flexible environment aligned with the real needs of contemporary engineering and architecture.
What is it

Centralized databases for data-driven budgeting.

BIM – Data – Planning integration
The platform operates as an integrated technology ecosystem, where BIM models, databases, and planning systems communicate bidirectionally through APIs, specialized services, and native plugins.
At the modeling level, Revit and Navisworks plugins capture information directly from BIM elements. Each object can contain technical, construction, and cost parameters that are automatically read, validated, and structured.
This data is synchronized with centralized databases, where it is linked to unit cost analysis, technical specifications, scheduling, and project control. The information can then return to the model as automation, technical validations, or decision-support signals.
As a whole, the platform functions as a BIM–data–planning integration engine: information flows from the model to the database and back to the project as control, technical consistency, and traceability.
The platform is fully BIM-compatible and designed to integrate directly into engineering and architecture workflows, connecting models, data, and automation within a single ecosystem.
How It Works

From BIM models to budgets with Revit and Navisworks

Use the apps inside Revit and Navisworks
Connect your models directly to centralized databases for budgeting, technical data, and project control. The plugins keep quantities, costs, and planning data consistent across the entire project lifecycle.
Revit Plugin
Connects the model with technical data and unit cost structures. Allows reading and writing parameters directly on elements, automating workflows and synchronizing the project with the central database for reliable budgeting and control.
Navisworks Plugin
Links models with planning and project tracking. Uses data from Revit and centralized databases to support 4D simulations, activity monitoring, and cost-driven project control.
Both plugins are free, database-driven, and part of an open-source platform designed for enterprise and on-premise deployments.
