The 10%-90% Rule of Estimating Dictates Who You Hire to Estimate

The 10-90 rule of an estimating strategy is— ten percent of your efforts will be spent on hard numbers, and ninety percent of your efforts will be spent on soft issues. So what do we mean by this? Ten percent of your estimating effectiveness is going to be on the hard numbers how much concrete the job will use, how much sand or base will the sub-grade take, how much will it cost to excavate the footings, how much labor will be used, how much rebar, how much tractor time, and how much equipment do we need on the job. That’s the ten percent.
