  1. CAD Drawing Requirements Developer Services Summit November 16, 2010 Presented by Donna Short

  2. CAD The Past The Past – Pre 2005 • Drawings were submitted to New Jersey American Water in AutoCAD format • New Jersey American Water extracted needed linework from Developer’s drawing and added them to the distribution maps in AutoCAD format • New Jersey American Water submitted revised distribution maps in AutoCAD format to NJDEP for SDW permits CAD

  3. CAD The Past – 2005 to 2010 • Drawings are submitted to New Jersey American in AutoCAD format • New Jersey American Water extracts needed linework from Developer’s drawing and adds them to the distribution maps in ArcGIS format • For projects requiring individual SDW permit applications, New Jersey American Water extracts specific project linework and provides data in ArcGIS format for submittal to NJDEP • For project in areas under Master Permits, New Jersey American Water provides an annual update to NJDEP of all proposed projects – list must match the NJDEP’s list of PAW projects. GIS

  4. The Past – 2005 to 2010 (cont’d) • Current Process in place since 2005 • Have logged over 1400 projects • Over 610 Different Applicants • Utilizing over 575 different Engineers • Resulting Issues • Over 1400 projects to track • Countless numbers of CAD standards • Time consuming process, regardless of SDW permit status

  5. The Present • Drawings are submitted to New Jersey American Water in a standard New Jersey American Water AutoCAD format • New Jersey American Water extracts needed linework from Developer’s CAD drawing and adds to the distribution network in ArcGIS format • New Jersey American Water exports data from GIS for SDW permit submittals, Individual or Master permits

  6. The Present (continued) • Developers/Engineers are able to draft plans utilizing their current CAD standards or directly in New Jersey American Water standard template • New Jersey American Water provides a drawing template in AutoCAD format along with step-by-step instructions for converting objects from original layering standard into New Jersey American Water’s layering standard • Standard block symbols are utilized and provided in template file • A “scaled down” version of the original design is submitted to New Jersey American Water for approval

  7. Benefits • All projects submitted to New Jersey American Water are in the same format • GIS essential objects are layered so that they are easily identified and separated from nonessential GIS objects • Conversion process is easy for developers and/or engineers to follow • Allows for more timely updates to GIS and thus more timely submissions to NJDEP

  8. Details of the Standard • Standard CAD drawing template with layering convention and blocks included • Attributed block symbols provided • Layering standard based on the National CAD Standard Format • Layer colors based on the One Call Format for Utilities • Step-by-step guideline for converting existing CAD drawings into New Jersey American Water Standard template file

  9. Logistics • Standard is available for download from the American Water website:http://www.amwater.com/njaw/working-with-us/doing-business-with-us/developers-customer-resources.html • First glance for developers was made available November 2009 • Standard went into effect January 1, 2010

  10. Results • We have seen varying levels of compliance with standard • Block symbols • Layers • Spatial accuracy • Time to input data from CAD files has decreased dramatically • Drawings are easier to interpret • Layering allows editors to grab only what they need • Consistent symbology eliminates guesswork • Act as training sessions for new employees
