- Ontario commercial mechanical contractors and estimators
- Worth noticing
- A tagged EF-2 with no fan-schedule row stays open until the estimator supplies a model or removes the tag.
Field notes
The sample separates quantities read from drawings, estimates based on named rules, and unresolved rows rather than treating them alike. One example measures a 42-foot duct route from two drawn segments and excludes the elbow; another leaves EF-2 open because the tag on MP-201 has no matching fan-schedule row on M-601. The page also describes tracking changed sheets and notes on reissued tenders.
