Calibrating HyperEstimator

Basic Calibration Method

You will "calibrate" the HyperEstimator construction estimating software by getting it to hit right "on the nose " for one or more of your old projects.

NOTE-- We retired the MacNail and BidMagic estimating programs in 2000, and replaced them with Goldenseal construction estimating software. Goldenseal is an integrated program that also includes accounting, scheduling and contract writing. We keep these instructions online for our die-hard BidMagic and MacNail users! The calibration process for the Goldenseal estimating software, is similar to that for our older programs.

Once you've gone through and estimated one or more old projects, take a look at the detailed cost breakdown. To see it in print, click the Output button at the bottom of the window, then click on the Print Estimate button.

The printed estimate breakdown will show eighteen categories, each broken down into labor, materials and subcontractors. It will also show an overall project cost (lower right), plus a cost per square foot of finished floor area.

Compare the overall cost and the itemized costs with what you think the project should cost-- either from actual job costs, or from your own estimate of costs.

If you see any significant differences (greater than 5% overall, or greater than 25% for any line item), you can use any of several methods to get the numbers in line.
