MacNail Estimates

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.

Using MacNail Estimating

When making a test project for the MacNail construction estimating software, first choose *Fixed Costs from the MacNail menu, and type in wage rates (including burden), sales tax rates, and overhead, profit and contingency percentages. Leave all of the fudge factors set at 1 (one) for now.

Next, choose *Dimensions from the MacNail menu, and enter information about the size of the project. If any dimensions don't apply to the project, you can leave them blank. See the MacNail Estimating software manual for a further explanation of what to use for each dimension.

Finally, choose *Specifications from the MacNail menu, scroll down through the list of specifications, and include any items that are actually a part of the project you are estimating. If the "suggested" quantity looks correct, you can choose *Include in Bid from the Edit menu. If some other quantity is needed, you can type it directly into the "units used" column for that line.

You'll probably want to set aside at least an hour just to check through the blueprints and spec sheets, looking for details that will cost more than "standard" methods of construction. If any specialty items are not normally included in the MacNail Specifications section, add them into the "other" row in the appropriate category in Specifications (or use *Add Rows to add a new line).

For items that you normally subcontract, you won't have to spend as much time, but still go through Specifications and put in at least ballpark numbers for basic items such as foundation size, plumbing fixtures and electrical switches and outlets. By calibrating these items as well, you'll be able to second-guess your subcontractors-- giving you a double-check against their bids, and a cost you can use in emergencies if you can't get subcontractor bids.
