If you are looking for guidance for how to conduct excavation around underground facilities the Best Practices gives you the information you will need to get the job done safely.
The Best Practices Committee developed the following guide based on the Common Ground Study, which includes the primary section with Practice Statements and Descriptions as well as Appendices A through D. The verbatim restatement of all ancillary material contained in the original Study is available on the CGA Web site and is intended as an historical reference point for those persons interested in a more detailed background of the Best Practices. The stakeholders involved with the original Common Ground Study never intended that the Best Practices would constitute a static model. Rather, they intended it to be a working document that would evolve over time as more was learned and as technology advanced.
