Every plan set has gaps — not mistakes, just the limits of what a drawing can show before it hits the field.
What drawings leave out
Substrate condition, existing finish tear-out scope, ceiling height variance, and utility rough-in conflicts rarely show up cleanly on a 2D plan. A finish schedule might call out a tile assembly without specifying whether the existing slab needs leveling — and that omission becomes the contractor’s problem mid-install, not the estimator’s problem on paper.
Where we flag it
During takeoff, gaps like this get flagged with a specific RFI before the bid goes out — not folded silently into an assumption. That way the number you submit reflects a documented assumption the GC has seen, not a guess that surfaces as a change order after award.
Addenda tracking matters as much as the base set
A stale addendum count is one of the most common ways a bid ends up scoped to the wrong revision. We track every addendum number and date against the current bid set before finalizing quantities.
