Subscription Coordinate & Collaborate

AEC document management system with folder-level version control, document versioning, and collaboration workflows (distinct from 12d Model civil engineering software).

2.8 /5 composite score

C1 3/5 reflects subscription pricing; C2 2/5 reflects integration-centric architecture with limited public API; C3 3/5 reflects cloud-based onboarding; C4 3/5 reflects document-centric workflows with some export; C5 3/5 reflects integrations with civil and industrial projects. Distinct from 12d Model (civil authoring software); folder-level version control focus.

Alternatives in Document Control

Microsoft OneDrive & SharePoint

Cloud file storage and document management layer of Microsoft 365 -- OneDrive for Business provides personal cloud storage and file sync, while SharePoint document libraries serve as shared team repositories for drawings, specifications, models, and project documentation, forming the de facto CDE backplane for AEC firms on M365.

4.6/5

Google Workspace (Drive & Shared Drives)

Cloud productivity and file storage suite centered on Google Drive -- personal My Drive and team Shared Drives provide cloud-native file storage, sharing, and real-time collaboration on Docs, Sheets, and Slides, used by many AEC firms as a lightweight document repository and collaboration layer alongside CAD/BIM authoring tools.

4.6/5

Dropbox

Cloud file storage, sync, and sharing platform used by AEC firms as a project document repository for CAD, BIM, PDF, and visual content files -- with team folders, version history, large file transfers, e-signature (Dropbox Sign), video review (Dropbox Replay), and AI-powered search (Dash).

4.2/5

iTwin Platform

Open, scalable cloud platform providing REST APIs and TypeScript SDKs for developers to create digital twin applications. Enables incorporation of engineering data from design tools into living digital twins aligned with reality data across infrastructure asset lifecycles. Serves as the foundational cloud layer for all Bentley infrastructure products.
