SIRADOS Baudaten

What SIRADOS Baudaten does

SIRADOS Baudaten is a German provider of construction cost data (Baudaten) for architects, planners, and construction contractors, operating as a brand under WEKA Media GmbH & Co. KG and headquartered in Kissing. The company has documented German construction prices continuously since 1984, publishing a 'Von-mittel-bis' (from-average-to) price band model derived from actual bids and tender documents. Its data library covers approximately 22,800 Neubau positions, 10,400 Altbau positions, 7,800 Tiefbau/GaLa positions, and 15,400 Technik positions, refreshed three times per year. Content is delivered through the SIRADOS 365 platform (browser and Windows desktop), a suite of subscription data packages (Architektur, Bauunternehmer, Kostenplanung, Kalkulationsdaten), and annual printed reference works. VOB-compliant tender texts, DIN 276 cost planning, GAEB data exchange, regional Ortsfaktoren adjustments, and AI-supported pricing form the core functional stack.

Revenue is generated primarily through annual subscription licenses (€157–€2,188 per product, auto-renewing), supplemented by physical handbook sales and a pay-per-use SIRACOINS token system. Distribution combines direct B2B e-commerce via sirados.de with embedded delivery through third-party AVA and construction calculation software partners via GAEB and API integrations, plus a network of building product manufacturers and cooperation partners. Customers are segmented between architects/planners (cost planning, tendering, price verification) and contractors/craftsmen (bid calculation, offer preparation), with secondary exposure to building owners and educational institutions. SIRADOS is Germany-only, ISO 27001 certified, a member of the Bundesverband Bausoftware (BVBS), and holds no disclosed funding rounds or M&A history; reported SIRADOS-specific headcount is 1–10, with shared services likely carried by the parent WEKA Media group.

Broad incumbents

• RIB Software (Schneider Electric): RIB (now part of Schneider Electric) is a leading German AVA/iTWO construction software provider covering tendering, awarding, billing, and cost planning across the full lifecycle. As a broader AEC software incumbent with AVA workflow depth, it competes with SIRADOS's emerging SIRADOS 365 AVA module at the platform level.
• Nevaris (Nemetschek Group): Nevaris is the Nemetschek Group's German-speaking construction software brand covering AVA, cost planning, and ERP. It provides construction software platforms that integrate tendering data and represents a broader incumbent that can incorporate or substitute for SIRADOS's data within a single vendor stack.
• BRZ Deutschland: BRZ is a German construction ERP and AVA software vendor serving mid-market contractors with integrated tendering, calculation, and billing workflows. Its construction calculation modules overlap with SIRADOS's Bauunternehmer und Handwerker offerings from a software-platform angle.

Emerging players

• Cosuno: Cosuno is a German construction tendering and procurement SaaS platform that digitizes the bidding process for trades and contractors. It is an emerging player targeting the same tendering workflow with a modern, AI-augmented UX that could overlap with SIRADOS's SIRADOS 365 AVA positioning.

Others

• Bausteine-Online / Sirados-Konkurrent StLB-Bau Vertrieb: Bausteine-Online and related German tendering-text distribution services channel STLB-Bau and similar standardized text libraries into AVA programs, mirroring SIRADOS's distribution pattern via software partners and serving overlapping German architect and contractor workflows.
• BauInfoConsult: BauInfoConsult is a German construction market research and information services provider producing studies, reports, and market data for the German building industry. It is adjacent to SIRADOS through its data-publishing model and shared end buyer (architects, planners, building product manufacturers).

Direct peers

• Heinze BauOffice: Heinze is a long-established German construction information services provider offering product catalogs, BIM data, and reference information to architects and planners. It overlaps with SIRADOS's content-and-data subscription model aimed at the same German AEC professional audience.
• STLB-Bau (Dynamo Bauwesen): STLB-Bau is the German standard performance description library for construction tendering, distributed as a building-block text system integrated into AVA programs. It competes with SIRADOS's VOB-compliant Ausschreibungstexte for the same tendering workflow in German construction planning.
• BKI (Baukosteninformationszentrum Deutscher Architektenkammern): BKI is the German construction cost information center jointly run by the federal and state architects' chambers. It publishes building cost data, cost benchmarks, and reference values for cost planning per DIN 276 — a direct competitor to SIRADOS's core Baudaten offering, sold to the same architect and planner audience in Germany.

Regional players

• California Software (CYPE): CYPE is a Spanish construction cost data and software provider offering construction prices, generators, and BCA/DBO data packages across Spanish-speaking markets. It is a regional peer operating a comparable data-driven cost planning and tendering model in a different geography.
