A construction schedule the site actually updates.
ConaPlan connects the plan in the office with what happens on site. The project manager plans in a Gantt chart; the foreman confirms activity status from the phone and files a voice report in half a minute. You see delays, problems and the forecast finish the same day — not at month end.

What is ConaPlan
One app for the plan and the site.
ConaPlan is construction project software from Slovenia that combines a construction schedule (Gantt chart) in a web app with site reporting in a mobile app for iOS and Android.
You build the schedule or import it from MS Project, Primavera or Excel. The site keeps it current with status confirmations, problem reports and voice reports that become a clean PDF — groundwork for the official site diary. The manager sees what is late, what is on the critical path and when the project will really finish.

How it works
From plan to confirmed status
The plan stays in the office, the status comes from site. Nothing in the plan changes without your approval.
01
Import or build the plan
Open an existing schedule from MS Project (.mpp, .xml), Primavera (XER, P6 XML) or Excel / CSV, or build it in the Gantt chart. Durations are counted in working days with public holidays.
02
Assign the work
Assign activities to crews. ConaPlan warns about double bookings, and subcontractors confirm their activities through a link — no account, no app.
03
The site reports
In the mobile app the foreman confirms status ("on plan", a percentage, or "behind" with a reason), reports a problem or records a voice report. Works without signal too.
04
You decide
Approve or reject progress from site; plan changes go through a proposal and approval. A weekly report can arrive by email automatically every Monday.
Features
Everything from schedule to report.
Construction schedule
Planning in the web app
A Gantt chart that counts the way builders do: in working days, with dependencies and deadlines.
Working-day Gantt
Slovenian public holidays built in, Saturday as a working day switchable per project, Sunday never.
Dependencies and deadlines
Finish-to-start, start-to-start and finish-to-finish links with lags (negative too), start-no-earlier-than, fixed finish and milestones.
Import existing schedules
MS Project (.mpp and XML), Primavera (XER and P6 XML) and Excel / CSV with column mapping. Before importing you see a date comparison and warnings by row.
Critical path and float
Total float for every activity, critical activities and the links that drive the project finish, highlighted in the Gantt chart.
Schedule health
Nine automatic checks: activities without predecessor or successor, long lags, start constraints hiding logic, unreachable fixed finishes, double-booked crews.
Finish forecast
From actual dates and percentages ConaPlan calculates when the project will really finish — next to the plan, without overwriting it.
Versions and baseline
Saved schedule versions, a baseline, a comparison of any two versions and a change history for every activity.
Change proposals
A manager drafts a changed schedule with a reason; the owner approves or rejects it. An approved proposal becomes a new version.
Crews and 3-week lookahead
Crews with availability, double-booking warnings and a three-week lookahead by crew — on screen and as a PDF for the site meeting.
On site
The mobile app for the foreman
Built for the site, not the office: voice instead of typing, one tap instead of a form.
Voice report to PDF
The foreman talks instead of typing. AI transcribes the recording and structures it into a report with weather and photos. Clean groundwork for the site diary.
Review before sending
No report goes out without the foreman's confirmation. The step is built in and cannot be skipped.
Multilingual reports
One report, one PDF, each language on its own page — client, contractor and supervision each read their own language. Emailed to every recipient on the project.
Daily activity view
Activities from three days back to seven days ahead. Confirm status with one tap: on plan, a percentage, or "behind" with a reason.
Problem reports
Missing material, too few workers, the previous crew not finished, unclear drawings, weather. The problem shows up in the plan immediately.
Works without signal
Reports, confirmations and problem reports are stored on the phone and sent automatically once a connection is back — without duplicates.
Team and reporting
Subcontractors, roles and the weekly report
Everyone sees their part; the person responsible for the deadline decides.
Subcontractor link
Each crew gets its own link: it shows only that crew's activities, answered with "confirm", "problem" or "not sure yet". Subcontractors do not count as users.
Roles and invitations
Owner, manager and field. The owner invites members with a code, managers plan, field members report. Only the owner changes fixed finishes.
Confirmation from site
Progress from site is a proposal until a manager approves or rejects it. Actual starts and finishes are recorded with a date and an author.
Weekly report
Progress, delays, open problems, schedule changes and next week — on screen, as a PDF and by email — optionally every Monday at 7:00, also to the client or supervision.

FAQ
Frequently asked questions
What is ConaPlan?
ConaPlan is construction project software that combines a construction schedule (Gantt chart) in a web app with site reporting in a mobile app, in one account. The schedule is kept current by status confirmations, problem reports and voice reports from site.
Does ConaPlan replace the site diary?
No. The official site diary is a separate document kept under the applicable regulations. ConaPlan prepares clean daily groundwork for it: dated reports with photos, weather, activity progress and problems, from which the diary is filled in quickly.
Can I import the schedule I already have?
Yes. ConaPlan imports MS Project (.mpp and XML), Primavera (XER and P6 XML), Excel and CSV. Before importing it shows on how many activities the dates match the original and lists every warning by row. Schedules are imported into an empty project.
Do I have to give up MS Project?
No. If you plan in MS Project or Primavera, import the schedule into ConaPlan and run the execution from there: status confirmations, problems, reports, versions and the finish forecast.
Do subcontractors need an account?
No. Each crew gets a link that shows only its own activities, where it confirms them, reports a problem or answers "not sure yet". Subcontractors do not count toward the user limit.
Does the mobile app work without signal?
Yes. Voice reports, status confirmations and problem reports are stored on the phone and sent automatically once a connection is back.
Which languages does ConaPlan support?
The planning web app is currently in Slovenian. The mobile app is in English, German, Croatian, Slovenian and Albanian. Site reports can be translated into any language — each language gets its own page in the PDF.
Where is the data stored?
The database is in Frankfurt, the application server in Amsterdam and the automations on servers in Germany. Report transcription and structuring use AI providers (OpenAI, Anthropic). Every processor is listed in the privacy policy; we sign a data processing agreement (DPA) on request.
How does the trial work?
The trial lasts 14 days and includes every feature of the chosen plan. A card is required at signup; unless you cancel before the trial ends, the subscription starts automatically. Prices are net, excluding VAT.
Who makes ConaPlan?
ConaPlan is made by ConaBox in Slovenia. It is built by a civil engineer with twenty years of site management experience — which is why it counts in working days, knows public holidays and keeps the plan apart from what actually happened.
A schedule that knows what is happening on site.
