Hello Tom DeWitte:
Is Utility and Pipeline Data Model (UPDM )2019 database model free of charge and can be used as to build business applications? And whom to contact in case support is needed?
UPDM is provided on GeoNet as a free download. There is no charge for using the data model. Yes, you can use it to build business applications. We have many Esri business partners who have done this.
