Explore DTCD for agencies →Do I need the dashboard or the mobile app?
Use the dashboard for planning, the field map and shared review. Use the mobile app for capture on site. They serve different parts of the closure workflow; a planning draft still needs to be saved as a field revision before placement can be recorded on the field map.
Can the crew document work without a signal?
The mobile app supports offline documentation and retries syncing saved closures when connectivity returns. Online maps, roadway lookups and sharing need a connection.
Can I bring in an existing alignment?
Plan Studio supports survey-alignment imports including KML, GeoJSON, CSV, DXF and LandXML. Check coordinates and road geometry after import before using the draft.
Is a generated plan automatically approved?
No. Plan Studio helps prepare and check a draft. Your team must verify the road, inputs and setup and obtain the engineering review and agency approvals required for the project.
How do I check my state's requirements?
Use the state documentation reference and confirm the applicable project specifications and agency format. Coverage and available roadway data vary; review the final plan and report for the job.
What if I want to start with documentation?
Start with one closure in the mobile app, capture its devices and photos, and review the resulting diary. You can introduce the planning workflow as your team needs it. Download the free diary template to see the information a daily record needs.
