As of today, the ConstructConnect Web Takeoff feature is being retired. This means you will no longer see a Web Takeoff tab within ConstructConnect Document Viewer. To continue performing takeoffs with a powerful free tool, see On-Screen Takeoff Planviewer or contact customer support for more details.
OST-Connect must be uninstalled and reinstalled to update to the current version. For steps on how to reinstall OST-Connect, see Creating (Importing) a Job from ConstructConnect into OST using OST-Connect.
