Loop Drawing Guidelines

Loop Drawing Maintenance Standard Operating Procedures

As part of CIP work, all completed and approved loop drawings are loaded onto each facilities’ Distributed Control System (DCS).  From the DCS, the local plant staff has the ability to view, print, and redline the loop drawings, as necessary.  The master electronic copies reside on the Public Utilities Department's network servers and are under the stewardship of the Computer Aided Design and Drafting (CADD) Section.  All CADD and loop drawing standards shall be adhered to as defined in the Clean Water Operations Management Network (COMNET) Project Standards and Procedures Manual.

All Loop Drawing CADD files created, modified or revised by design consultants, contractors or City staff shall be submitted on a CD (or DVD), along with paper prints of each, to the Information and Organizational Support Division’s Control Systems Administration & Support Section (IOS/CSAS) for technical review and approval, and to the CADD Section for CADD review and approval.  All loop drawing CADD work must be prepared using City-standard Bentley MicroStation® CADD software. For CSAS assistance, contact Mike Eells (858) 614-4011 or Dan Carreon (858) 654-4285 and for CADD assistance, contact Chris Hackney (858) 654-4428 or Joe Meyers (858) 292-6389.
