ERP for Construction
The German construction industry (Bauhauptgewerbe and Ausbaugewerbe) covers companies from large general contractors (Hochtief, Strabag, Bilfinger, Wolff & Müller, Goldbeck) through specialist trade contractors (electrical, plumbing, facade, roofing) to property developers and engineering firms. Construction ERP differs sharply from manufacturing ERP through project-business orientation, VOB billing (Verdingungsordnung für Bauleistungen), subcontractor management and increasingly BIM integration for digital project delivery.
Construction-specific ERP requirements
- Project structure with multi-level WBS, phases, milestones, percent-of-completion accounting
- VOB billing — VOB/B contracts with structured schedules, change orders, partial payments and retentions
- HOAI billing for engineering services (Honorarordnung für Architekten und Ingenieure)
- Subcontractor management with framework agreements, on-site dispatch, payment certifications
- Equipment and rental management — internal equipment fleet plus rental equipment tracked by project
- Material logistics — just-in-time delivery to construction sites, returnable packaging tracking
- BIM (Building Information Modelling) — integration with Revit, Allplan, ArchiCAD for quantity take-offs and project coordination
- Construction-site management — site personnel hours, equipment utilisation, daily reports
- Health and safety documentation compliant with construction-specific regulations (SiGeKo, Baustellenverordnung)
Top ERP vendors for construction
Specialist construction ERP DACH: RIB iTWO 5D / iTWO costX (largest DACH construction-ERP), Nemetschek (Allplan, Bluebeam plus connected ERP), pds (especially trade contractors), Microtech Bau, BRZ (specialist for mid-market construction), Sander & Doll Construction, Hottgenroth Bau-Streit. General ERP with construction add-ons: Microsoft Dynamics 365 Business Central with construction ISVs (Trovarit-listed partners), SAP S/4HANA with construction industry packages, Sage 100 Trades & Crafts with construction extensions, abas ERP with construction modules. Project-business ERP: IFS Cloud, Microsoft Dynamics 365 Project Operations — suit engineering-heavy construction firms. SMB: orgaMAX Bau, Lexware Trades & Crafts Bau, RIB SoftTech for small contractors. For large general contractors, RIB and Nemetschek dominate; for trade contractors, pds and specialist DACH platforms; for project-business engineering, general ERP with project-business strength.
BIM integration
BIM (Building Information Modelling) shifts construction from drawing-based to model-based project delivery. The BIM model contains structured component data (walls, doors, mechanical systems) with quantities, properties and lifecycle information. ERP integration with BIM: (1) Quantity take-off: BIM-driven automatic generation of structured bills of quantities for tendering and procurement. (2) Cost estimation: link BIM model elements to ERP cost categories and supplier prices. (3) Construction-site execution: BIM-derived work-package definitions flow to ERP for resource scheduling and tracking. (4) As-built handover: completed BIM model with operational data feeds the owner's facility-management ERP for ongoing operations. Specialist tools (RIB iTWO 5D, Bentley Construction Cloud, Autodesk Construction Cloud) orchestrate the BIM-ERP integration layer.
Typical construction company profile
A typical DACH mid-market construction firm: 100-500 employees, 50-300 million EUR annual revenue, 20-100 active projects ranging from 100,000 EUR to 20 million EUR each, multi-trade or specialist-trade focus, subcontractor network of 50-300 partners. The ERP runs RIB iTWO, pds, Microsoft Dynamics 365 Business Central with construction add-ons, or BRZ. Total ERP TCO over 5 years: 1.5-5 million EUR including implementation, licences and ongoing support. Construction-specific: 200,000-600,000 EUR additional spend on BIM integration, mobile field-service apps for site personnel, and subcontractor-portal infrastructure.

Frequently Asked Questions
Why is project-business so important in construction ERP?
Because every project is unique with its own budget, schedule, contract terms and risk profile. Construction operates as a portfolio of one-off projects rather than ongoing production. ERP must support project-level P&L, percent-of-completion revenue recognition, project-specific cash flow and per-project cost control — capabilities that manufacturing ERP often lacks natively.
How is BIM changing construction ERP?
BIM creates a structured model-based information source upstream of ERP. The ERP increasingly consumes BIM-derived quantities and structures rather than maintaining its own parallel data. Construction firms investing in mature BIM workflows report material efficiency gains in tendering (faster, more accurate bids), procurement (better quantity accuracy, less material waste) and project handover (lower facility-management transition cost).
VOB versus standard B2B contracts — what does ERP need to handle?
VOB (Verdingungsordnung für Bauleistungen) is the German standard contract framework for construction services, with specific rules on quantity-based billing, change orders (Nachträge), retention amounts (Sicherheitseinbehalt), defects-liability period and acceptance procedures. Construction ERP encodes these patterns natively; non-construction ERP needs significant customisation to handle VOB properly.
