ESTIMATING AND BIDDING MISTAKES
 
Estimating mistakes are made during the takeoff process.  Bidding mistakes are made in the summarization and submission of the bid.  An incomplete estimate and incorrect estimate are not the same.  An incomplete estimate has omissions.  An incorrect estimate maybe complete, but it could be based on an incorrect labor column and incorrect labor mix.
 
The following are common mistakes:

  1. Missed takeoffs on the drawings
  2. Failure to highlight items as they are taken off
  3. Missing documents

  7. Failure to get your material counts to suppliers early.
  8. Using branch wiring averages
  9. Using square foot pricing
  10. Failure to set material and labor units the same – E, C, or M.
