WHAT IS THE CM/UFM PRODUCT - 1

• Separately  licensed  ArcFM product

• Conduit  Manager  (CM):  Provides  a  base  set  of  tools  for  configuring  duct  banks  and  placing  conductors  in  ducts

• Generates  cross  section  annotation  based  on  the  configuration  and  conductor  placement

WHAT IS THE CM/UFM PRODUCT - 2

• Also  provides  trace  functionality  on  the  underground  geometric  network

• Underground  Facility  Management  (UFM):  Provides  a  base  set  of  tools  for  generating  butterfly  diagrams

• Includes  triggers/updaters  to  maintain  the  diagram  as  edits  as  conductor  is  added,  edited  or  removed  from  Duct  Banks

UFM CHALLENGES FOR PG&E• Try  to  stay  with  a  COTS  solution  as  much  as  possible• Data  density  and  whitespace  management• Overlapping  vaults  and  butterfly  diagrams• Stay  true  to  existing  map  products  for  cross  section  anno• Annotation  angling• Maintaining  data  integrity  (Validation  rules)

SF IS REALLY, REALLY DENSE…• Market  Street Overlapping  Vaults

FEATURE DENSITY SOLUTION• Multiple  Views  (Stored  Displays/MXD’s)• Conduit/Duct  Banks• Primary• Secondary/DC

• Individually  whitespacemanaged

• Users  must  switch  between  views

FEATURE DENSITY SOLUTION – MULTIVIEW 1

• Conduit/Duct  Banks

FEATURE DENSITY SOLUTION – MULTIVIEW 2

• Primary

FEATURE DENSITY SOLUTION – MULTIVIEW 3

• Secondary/DC

OVERLAPPING VAULT SOLUTION

• Vault  number  assigned  to  all  diagram  features

• Custom  tool  to  select  vault  number• Updates  diagram  layers  to  filter  features

• Integrates  with  ArcFM UFM  diagram  manager  for  editing

• Separate  toolbar  for  viewing

OVERLAPPING VAULT SOLUTION

CROSS SECTION ANNO SOLUTION -1

• Custom  Cross  Section  Annotation  • Modified  header  indicateS direction  x-­‐section  

represents  (N,  S,  E  or  W)• Shorthand  conductor  annotation  notation  

for  whitespace• Multiple  ‘copies’  generated⁃ At  1:600  scale  for  downtown⁃ At  1:1,200  scale  for  less  dense  areas⁃ Stored  Display/MXD  controls  visibility

CROSS SECTION ANNO SOLUTION - 2

• Other  rules,  Eg:⁃ Single  conductor  placed  that’s  split  between  ducts

⁃ Conductor  counts  split  by  phase⁃ Multiple  conductors  in  ducts⁃ Conductors  not  modelled  in  ducts  (Telco/BART)

ANNOTATION ANGLING• Virtually  all  SF  streets  run  ~45degs  from  north• COTS  tools  reset  annotation  angle  on  update• This  includes  cross  section  annotation• Also  duct  annotation  in  butterfly  diagrams

• When  new  conductor  is  placed  into  duct,  the  angle  is  lost  and  whitespace  management  ruined

• Solved  with  custom  trigger  to  calculate  “shallowest  upright  angle”  when  edited

VALIDATION• QA/QC  Rules  to  ensure  vault  diagram  data  integrity• That  conductor  has  been  placed  in  a  duct• That  the  x-­‐section  direction  has  been  set  on  duct  bank• That  duct  banks  have  been  configured• That  duct  bank  butterfly  representations  are  placed  in  vaults  on  both  ends• That  duct  bank  butterfly  representation  is  consistent  w/direction  specified• That  duct  bank  butterfly  representations  on  each  end  are  mirrored

• Used  to  validating  migration  effort  and  for  ongoing  data  maintenance

CURRENT AND NEAR FUTURE USES• Integrated  asset  information• Publishing  complete,  detailed  and  up  to  date  drawings  for  field  

activities  from  one  source  of  truth• Singular  record  keeping  for  MH  butterfly,  Duct  Configuration,  

Conduit  System  and  Duct  Occupancy• Duct  availability  tractability  -­‐ future
