Scope: This guide has been prepared to assist those specifiers@ public agencies@ shotcrete applicators@ shotcrete users@ testing laboratories@ and others who may find it desirable to broaden their own knowledge and/or to establish a procedure for training and certification of shotcrete nozzlemen. Since at this time@ no official certification programs based on this guide are recognized@ modifications in procedure and questionnaires to suit local requirements are encouraged. Nothing included herein is mandatory@ this being only a guide with the goal of eventual establishment of a uniform national certification program for shotcrete nozzlemen. Training and examining personnel will find the bibliography and certification procedure in the guide to be helpful tools in any educational program to: (1) train new nozzlemen and other members of the shotcrete crew; or (2) increase the knowledge and broaden the capabilities of their trained personnel to possibly include additional types of shotcrete applications. This guide does not imply that an individual nozzleman is required to prepare himself unaided for certification@ although that possibility is not precluded. It is the intent that qualified personnel@ with the aid of this guide@ references included herein@ and other experience@ will train and prepare candidates for certification.
