Overview

Construct CT offers full offline capability to allow users to create, update, and manage crews, members, activities, equipment, and timesheets even when offline.

When back online, local data automatically synchronizes with the server following conflict resolution rules.

Offline synchronization ensures continuous productivity while conflict handling prevents data duplication and maintains data consistency.

For more information about what features are supported offline, please refer to Construct CT - Offline Data Management.

Local Databases

While connected to the internet, the app downloads all information from the chosen server to the user's local device. The user's local database should be up to date so long as the app has not been deleted and reinstalled.

If the user is installing the app for the first time, the local database is empty and the user must log in with an internet connection and select the default project and crew. This will then download all crew members and jobs to which the user has been given access in E-Time security.

Users can download timesheets from the local server by accessing each day of the week on the timesheet. In the screenshot below, the user has pressed on each tab for the days of the selected week to ensure that local and server data are synchronized.

Available crew members, tasks, and equipment can also be downloaded on a fresh install by pressing the [Add Crew Member], [Add Activities], and [Add Equipment] buttons found in the Crew Maintenance screen.

Once this information has been downloaded locally, the Construct CT app supports both timesheet entry and access to the Crew Dashboard. Any time entered offline is saved locally on the user's device and will synchronize with the server when an internet connection is re-established.

Synchronization Workflow

General Conflict Handling Rules

The following options are available:

• Retry: Press the [Retry] button to reattempt the upload.

• Discard : Select the "Discard" option to remove the local record.

• Rename: Assign a new unique code for unique-key conflicts.

• Merge: Select the "Merge" option to combine local and server data to preserve both.

Conflict Handling by Screen and Entity

Crew Maintenance	Partially	Crew Code must be unique. On sync, user prompted to Merge, Rename, or Discard if Crew Code exists on server. Crews cannot be deleted once timesheets exist.
Members Tab	Yes (partial LOV support)	One entry per Employee per Crew. Multiple trade/union combinations allowed per employee (Employee ID + Trade ID + Union ID). Members removable before timesheet approval. Duplicate entries ignored silently.
Activities Tab	Yes (partial LOV support)	Multiple entries allowed per Crew. Duplicates merged or ignored automatically.
Equipment Tab	Yes (partial LOV support)	Equipment unique per Crew. Duplicates ignored silently.
Approver Tab	Limited (auto-syncs when crew header syncs).

Best Practices

• Sync at least once every 24 hours to avoid large conflict batches.

• Resolve conflicts promptly to prevent data loss.

• Use "Merge" to preserve continuity.

• Avoid reusing crew codes for different projects.

Troubleshooting

If sync errors persist, check the Synchronization Log for parent issues.

• Retry after resolving parent-level conflicts.

• Export logs and contact CMiC Support if issues continue.
