Control over documents. Lower project costs. Prostream.
One place. One up-to-date version. Less rework.
Prostream is document management software that enables project teams to work from one central, up-to-date version of documents and drawings.
Trusted by project teams in construction, infrastructure, and the public sector:
The problem:
Fragmented project information costs time and money
In many construction projects, unnecessary time and money are lost. Not because people aren’t doing their jobs properly, but because project information is fragmented:
- Multiple versions of drawings
- Documents shared via email, messaging apps, and downloads
- Uncertainty about which version is the latest
It’s obvious that working with the wrong version costs time and money. But the doubt itself — “Is this really the latest version?” — also causes delays and ultimately leads to extra costs.
What fragmented project information really costs €
The impact of this fragmentation is significant:
- 5–20% of project costs are spent on rework;
- Almost half of that is caused by incorrect, missing, or unclear information;
- Project teams consistently lose time searching, coordinating, and fixing errors.
Not because people aren’t doing their jobs properly, but because it’s unclear which information is leading.
The solution:
One central source of truth
The problem usually isn’t missing information.
More often, it’s not clear which version applies.
Especially when documents are shared with multiple parties — both internal and external — confusion about versions quickly arises. Tools like SharePoint or Dropbox store files, but they don’t define which version is leading.
Prostream brings structure to existing project information. Not by changing everything, but by clearly defining which version applies. For everyone.
Always work from the right version
Prostream brings all project documents together in one place:
- Always the latest version. You work by default with the most up-to-date version;
- No confusion. Previous versions remain available without getting in the way;
- Easy sharing. Share documents securely with colleagues and external partners via a single link;
- Full overview. See what has been shared and with whom.
This way, everyone involved works with the same information, reducing the risk of errors caused by version confusion.
In practice, this means you always maintain full oversight of your project — both in the office and on site. Documents, comments, and tasks are shared effortlessly with internal colleagues and external partners. And everything happens securely, within a single environment that is fully GDPR- and ISO/IEC 27001:2022-compliant.
For who is Prostream?
Prostream connects office and site, giving everyone control over the project.
In the office
For project managers and planners, this means:
- Documents clearly organized in one place;
- Sharing with internal colleagues and external partners without noise;
- Fewer questions about versions;
- Less time spent on explanations and rework.
This leads to more overview, more peace of mind, and more control over the project.
On site
For execution teams, this means:
- Quickly finding the right drawing via QR codes or shared links;
- Immediately seeing whether you’re working with the correct and most up-to-date version;
- Fewer corrections afterward;
- More focus on the work itself.
Even when not everyone works in the same system.
The result:
Less rework. More control over projects.
When project information is better organized:
- Errors decrease;
- Rework is reduced;
- Teams save time;
- Failure costs remain manageable.
This results in fewer surprises during the project, more calm in execution, and greater control over both planning and budget.
