PACP
Pipeline Assessment & Certification Program
Implemented in 2002
Program Purpose:
– Standardization and Consistency in sewer pipe condition evaluation
– Management of collected CCTV data.
Based upon Water Research Centre (WRc) codes (Swindon,
England)
Defect Coding System to document pipeline condition
Re-certification required every 3 years

MACP
Manhole Assessment & Certification Program
Developed In response to industry demand for a program
to code manhole defects
Version 6.0.1 (November 2010 Release): Two inspection protocols
– Level 1 inspection - basic condition assessment to evaluate general
condition
– Level 2 inspection - detailed information to document all defects & condition
MACP Coding
– Applies PACP defect coding system
– Incorporates ASCE manhole Standards.
PACP certification is prerequisite for MACP training & certification
MACP certification is valid for 3 years

Why NASSCO Train?
People have different:
– Perspectives
– Opinions
– Levels of Experience
– “Learned Eye”
Utility owners need measures to gauge:
– When to act
– When to wait
– When and how to prioritize
![Page 13: WEAT Collections Conference| January 22, 2014 NASSCO PACP](https://reader033.vdocuments.us/reader033/viewer/2022051216/62788812016ec04e5210badc/html5/thumbnails/13.jpg)
Why NASSCO Train?
To Compare One Pipe, Manhole, Lateral
evaluation to another and To Prioritize
System Needs, Requires:
Standardization
Consistency
Objectivity
Managed Data

Training Operations Staff
Operators have
– Hands on field experience
– Technical training
– Inspection knowledge and experience
– Field “learned eye”
Operators do not have
– Data analysis experience
– Design experience
![Page 15: WEAT Collections Conference| January 22, 2014 NASSCO PACP](https://reader033.vdocuments.us/reader033/viewer/2022051216/62788812016ec04e5210badc/html5/thumbnails/15.jpg)
Training Operations Staff
Operators are the eyes and ears of the
“office” reviewers
Operators are not technical/engineers… and
proud of it
![Page 16: WEAT Collections Conference| January 22, 2014 NASSCO PACP](https://reader033.vdocuments.us/reader033/viewer/2022051216/62788812016ec04e5210badc/html5/thumbnails/16.jpg)
Training Operations Staff
When you are coding, think about:
– Recording what you see thoroughly and consistently
– Code all defects regardless of repetitive/continuous defects in
segment.
– Don’t allow coding to become “relative” to severity of defects in pipe
– Don’t exaggerate or over emphasize a defect
– Don’t minimize or skip a small defect.
![Page 17: WEAT Collections Conference| January 22, 2014 NASSCO PACP](https://reader033.vdocuments.us/reader033/viewer/2022051216/62788812016ec04e5210badc/html5/thumbnails/17.jpg)
Training Operations Staff
When Performing CCTV:
– Field conditions make achieving clear & accurate video a difficult task
– Important to obtain the best recorded image feasible
• Camera Speed, orientation, and lighting are essential
• NASSCO has clear & detailed guidelines to assist in
achieving high quality video inspections & assessments
![Page 18: WEAT Collections Conference| January 22, 2014 NASSCO PACP](https://reader033.vdocuments.us/reader033/viewer/2022051216/62788812016ec04e5210badc/html5/thumbnails/18.jpg)
Training Operations Staff
Operators hands on experience and learned eye applied in coding can result in:
– Coding based upon real time view vs. recorded
view • Ex: Depth of a crack in the manhole wall
– Codes that reflect surrounding conditions • Ex: Crack with evidence of I&I
– Defect identification that may be missed or unclear
in recorded version • Ex: Hearing water travel down a manhole wall

Tips to Operators on NASSCO Training
1. Bring field experience with you; good opportunity to ask
questions of trainer & industry peers
2. Table your pre-conceived notions; you might actually
learn something you didn’t already know
3. Adopt PACP standards and use the training materials to
enhance your knowledge and experience; always room
for improvement
4. Appreciate that your job in field is critical to success of
system assessment; office staff are blind, deaf and dumb
without it!

Training Technical/Engineering Staff
Engineers have
– Data analysis experience
– Design experience
– Construction method knowledge
– Construction material knowledge
Engineers do not have
– Hands on field experience
– Technical field training
– Field Inspection knowledge and experience
– Field “learned eye”
![Page 22: WEAT Collections Conference| January 22, 2014 NASSCO PACP](https://reader033.vdocuments.us/reader033/viewer/2022051216/62788812016ec04e5210badc/html5/thumbnails/22.jpg)
Training Technical/Engineering Staff
Technical knowledge applied in coding review can result in:
– Coding based upon material degradation
knowledge vs. code applied • Ex: RCP pipe with rebar exposed
– Evaluating composite codes vs. one defect code • Ex: Pipe and manhole defects found
– Defect identification that may be missed or unclear
in field review • Ex: Lateral defect missed in CCTV coding of pipe

Training Technical/Engineering Staff
Tips to Technical/Engineers Staff on NASSCO Training
1. Bring your technical knowledge and experience with you; good
opportunity to ask questions of the trainer as well as industry peers
2. Table your pre-conceived notions; you might actually learn
something you didn’t know
3. What you learned in training/college can be different when applied
in the “real world”
4. Adopt the training materials to your knowledge and experience;
always room for improvement
5. Appreciate that you are reviewing work performed in field conditions
under varying conditions of weather and system operations; not
easy and many times a dirty job

Conclusions
NASSCO Training is Beneficial to Operators, Technical Staff and Engineers Alike
NASSCO Coding Does Not Replicate/Replace Knowledge and Experience
Combining Knowledge/Experience with NASSCO Principles is Key!
