Estimating Multi-Unit Construction

NOTE-- We retired the BidMagic construction estimating software in 2001. It has been replaced by Goldenseal construction estimating software.

We still include this BidMagic estimating software manual as a convenience for users of our older program. Many features are similar, in Goldenseal estimating.

Multi-unit Construction Estimating

The BidMagic estimating software can handle multi-family residential projects, or multi-unit commercial work. Simply choose the type of construction you are doing on the first Dimensions card, and enter the number of living units (or businesses).

NOTE: The number of rooms you can add in remodeling projects is limited only by memory. We have tested it for over 200 rooms with no problems.

How you'll handle multi-unit projects will depend on how the units are set up.

Many Identical Units

If you are working on a project that consists of many copies of the same identical unit, follow these steps:

  1. Prepare an estimate for one unit only.
  2. Multiply the total number of units by 100 and enter that number into the Overall Fudge Factor on the Basic Costs card.

NOTE: You may need to pro-rate overall project costs such as site utilities and design costs between the units.

For a 'clumped' project--for example, multiple buildings with four town houses each--follow the steps listed above, but use the cost of one building or one cluster in step 1.
