Integration Architecture for ENR-400 Contractors

briq Engineering · Enterprise Architecture · Nov 2025

Best practices for connecting ERP, project management, and financial systems in large construction organizations.

Large construction companies — ENR-ranked general contractors, national specialty firms, and multi-regional builders — face a unique integration challenge. Their technology stacks have grown organically over decades, with different systems chosen by different divisions for different reasons.

This whitepaper provides a practical architecture guide for connecting these systems without ripping and replacing. It's based on patterns we've observed across 100+ enterprise deployments.

We cover the three pillars of construction integration: data normalization (making different systems speak the same language), event orchestration (triggering actions across systems based on business events), and state management (keeping data consistent when multiple systems can modify the same record).

The paper includes reference architectures for the most common construction technology stacks: Viewpoint + Procore + Bluebeam, Sage + PlanGrid + Textura, and CMiC + Autodesk + Oracle Primavera.

We also address the organizational challenges: who owns integrations, how to handle change management, and how to build internal capabilities vs. relying on external partners.

The appendix includes a detailed integration assessment framework that IT leaders can use to evaluate their current state and plan their integration roadmap.
