DOC.project - virtual project room
Plans, documents, workflows - one source of truth for every party.
DOC.project is the web-based Project Communication System (PCS) for construction and infrastructure. Plan management with revision control, document workflows, a granular roles and permissions model - in productive use since 2001. More than EUR 15 billion of construction volume delivered with it to date.
Features
What DOC.project does in day-to-day projects.
DOC.project is the central hub (Common Data Environment, CDE) for your construction project. Every plan, document and workflow is held in an audit-proof single source of truth - browser-based and instantly available to owners, planners, general contractors, specialist designers and subcontractors. The result: less search time, no double-handling, far less plan chaos on site. We have grown the platform with users for users since 2001.
Revision control
All revisions (indices) of a document bundled into a single node. Automatic versioning by the system, access to earlier planning states at any time - continuous history.
Attachment management
Manage text, graphic and data attachments. Link main and secondary documents (e.g. PDF with CAD file) - every attachment bound to its specific revision.
Audit-proof storage
No full deletion of documents (view filter). Move to recycle bin with restore option.
Multi-upload
Transfer any number of documents in one step with monitored, error-free data transfer. Duplicate detection, automatic storage type and plan-code sorting.
Document search & quick viewer
Comprehensive search across attributes, descriptions and full text (including text content inside CAD files). Save individual queries, multi-download from results, previews. In the integrated viewer you mark up documents and add graphic and text annotations.
Messaging system
Closed messaging with guaranteed delivery confirmation. Instant delivery without transfer delays, individual distribution lists, project-wide address book, SMS/e-mail notification.
External stakeholders
External project participants without a login are pulled into the workflow via an e-mail download link. The download is logged in the system - inbox size limits are elegantly bypassed.
Workflow engine
An extended workflow engine monitors and steers routine tasks - seamlessly integrated with the messaging system, the document repository and the process module. Workflows are configured per client and map established company processes. There is no graphical drag-and-drop editor.
Construction diary link
Connection to the digital construction diary - for operational site management.
Internal plan release
Digital release stamp for execution plans (plot for the site), including allocation of a unique plan ID. Full traceability of which version was used on site.
Long-term archiving
At project end DOC.project provides the entire data set - including workflows, revision metadata and audit logs - in an offline structure that you can keep using in your own network, independent of the platform being in operation.
Architecture
Web-based core, open formats, secure integration.
DOC.project runs as a central web application. Every party connects through the browser - with controlled access, a documented history and defined workflows. The platform handles open formats such as PDF, DWG, DXF and DGN and ships with an integrated viewer: mark up documents and add graphic and text annotations - right in the browser, no local CAD licence required.
A Common Data Environment for everyone involved.
Whether owner, planner, general contractor, subcontractor or expert assessor - everyone works off the same data. Through interfaces we connect DOC.project to your existing IT landscape - backed by extensive integration experience.
From the field
Useful ahead of any roll-out: our PCS selection criteria - a checklist that helps you structure requirements cleanly.
Why DOC.project
Proven since 2001 - across more than EUR 15 bn construction volume.
DOC.project was not designed on a whiteboard - it was hardened in real construction projects: transport infrastructure, real estate portfolios, industrial and high-rise builds. Lessons from hundreds of projects are baked into the product, from the smallest detail (plan stamps) to strategic features (audit trail).
Revision-proof
Every file version is retained in full. Earlier planning stages remain accessible at any time - with a complete history.
Audit-ready
A tamper-proof audit trail of every transaction. Who did what, when? Admissible in court. The logs are delivered as part of the archive.
Granular Permissions
Configurable down to field level. Every role sees exactly what it needs - nothing more, nothing less.
Browser-only
No install, no CAD licence per workstation. Stakeholders are productive from day one.
ISO 27001
Hosted in Germany, regularly audited by DEKRA. On request: on-premise in the owner's data centre or private cloud.
Interfaces
Connection to your existing systems via bespoke connectors - backed by extensive integration experience.
Experienced
Productive since 2001, more than EUR 15 bn construction volume delivered. No start-up risk - just proven German engineering.

FAQ
Frequently asked questions about DOC.project
What exactly is a PCS - and how does it differ from a DMS?
A Project Communication System (PCS) is a Common Data Environment (CDE) for construction projects: plan management, revision control, workflows and a granular permission model across many different companies. A classic DMS manages documents generically - a PCS understands plan revisions, owners, planners, subcontractors, plan runs and formal acceptance procedures. For a clean delimitation see our PCS checklist.
What does DOC.project cost?
We offer transparent tiered pricing by number of project users and storage. Three packages are available (PROJECT, TEAM, ENTERPRISE) - details on Pricing 2026. For very large endeavours we agree pricing individually; that is the rule from 50 users upwards.
Where are my plans and documents hosted?
By default in our ISO 27001-certified data centre in Germany. On request we run DOC.project on-premise in your data centre or as private cloud - including SLA, backup and disaster recovery.
What interfaces are available?
DOC.project can be connected to your existing systems via connectors. We build the integration to fit your IT landscape and bring extensive integration experience to the job.
Is there a graphical workflow editor?
No. DOC.project uses an extended workflow engine; workflows are configured per client and map your established processes. DOC.project does not offer a drag-and-drop editor.
What happens to our data at project end?
Long-term archiving provides all data including workflows, revision metadata and logs in an offline structure. You can deploy and use this structure in your own network - without the platform in operation.
Can external parties take part without their own account?
Yes. External project participants are brought into the workflow via an e-mail download link. The download is documented in the system.
Can documents be deleted permanently?
No. DOC.project is audit-proof: documents are hidden via view filters or moved to the recycle bin and can be restored.
