- Electrical, plumbing, HVAC, fire-alarm, and low-voltage estimators
- Worth noticing
- The example points reviewers to circuit routing, E0.0 note 2, and a motor-controller specification after showing the drawing change.
Field notes
The example follows a spray-pump starter added beside panel L8 on sheet E2.1, then directs reviewers to check circuit routing, E0.0 note 2, and a motor-controller specification. It links the original and addendum PDF excerpts and identifies the documents as Norfolk Public Schools bid materials, with a credit to Morrissey Engineering, Inc. The page advises keeping the normal estimating and document-review process in place while coverage is validated.
