RENALDO provides a web-based operating system for residential construction that connects building data with prepared services, prices, and durations. The platform enables developers and housing companies to generate cost estimates, tender documents, and construction schedules from a single building model, reducing preparation effort and supporting faster, more informed decisions. It covers the full project lifecycle from portfolio strategy and feasibility through execution and handover.

Problem
Residential construction projects in Germany face significant inefficiencies because building data, cost calculations, tender documents, and construction schedules are typically managed in separate, disconnected tools. This fragmentation forces project teams to manually re-enter and reconcile data across multiple systems, leading to high preparation effort, inconsistent information, and delayed or poorly informed decisions.
Solution
RENALDO provides a unified operating system for residential construction that connects building data with prepared services, prices, and durations in a single data core. Users start by entering or importing building and room data, from which RENALDO automatically derives quantities and links them to pre-configured construction services, real regional craftsman prices, and typical durations. Project teams then review and refine this prepared foundation, and use it to generate cost calculations, tender documents (Leistungsverzeichnis), and construction schedules. The platform covers the entire project lifecycle from portfolio strategy and feasibility through execution, quality management, and handover, with all stakeholders working on the same shared project basis.
Target Audience
Primary customers are residential property developers, housing companies (Wohnungsunternehmen), and planning, project management, and construction management firms working on new builds and renovations in Germany.
Features
- Unified building model that automatically derives quantities and links them to services, prices, and durations, enabling cost and schedule generation from the same data source
- 3-Klick-Wirtschaftlichkeit (3-click feasibility) tool that calculates maximum affordable land prices and project viability early in the decision process
- Automated Leistungsverzeichnis (bill of quantities) generation from reviewed building data, with real regional craftsman prices and a cost-security indicator showing estimate reliability
- Self-generating construction schedule with quantity-dependent durations, dependencies, takt planning, and 4D simulation visualized directly on the building model
- Building data imports from IFC, Doorbit, Hottgenroth, and EVEBI formats without manual re-entry
- Mobile apps and a construction site portal for daily progress reporting, site inspections, defect tracking, and reactive schedule adjustment suggestions
- Portfolio and strategy module for housing companies to compare assets, prioritize renovation measures, and prepare multi-year investment programs
