Within Teamwork, you can create project templates from existing projects on your site.
Note: Project templates are available on per-user Pro (max 20 templates), per-user Premium (max 50 templates), and per-user Enterprise (unlimited templates).
Click the options button (three dots) to the right of the project name and select Save as Template from the Manage Project section of the dropdown.
In the Save as Template modal, you can choose a name (required) and company as well as update the description. Click Next step to proceed.
You can then choose which project items to carry over from the existing project to the template.
At the bottom of the modal, you can also choose to override current assignees and instead make yourself the creator of tasks, files, and copied messages.
Once you have chosen your preferences for the template, click Save.
