When performing a takeoff, IntelliBid will automatically calculate quantities for assemblies and items. These quantities are derived through a combination of multipliers and formulas. You can change the quantity of any item you’ve taken off by double- clicking in the quantity column for that item and typing in whatever quantity you want.
If you find yourself continually making the same change to an item, you might consider making the change permanent by updating the item’s multiplier or formula. This is done in Item Library Maintenance. In this Tip, we will we will look at editing the multipliers – we’ll save formulas for a future tip.
In our example, let’s say you find yourself adding 5% to the branch wire in every takeoff. This is a perfect opportunity to update some multipliers. Go to the Maintenance menu on the left side navigation bar, select Item Libraries and answer Yes when prompted to backup your database.
1. The first Item Library you will see is Fixtures.
2. Select the Catalog Fixture Assembly w/Branch. Scroll down the Catalog list and select EMT catalog.
3. If you look at the WIRE category listed below, you’ll see the multipliers (column M) are all set at 1.10. This means, for every foot of wire you’re going to get 10% extra wire for makeup and waste.
As we mentioned earlier, if your experience shows that you need 15% extra instead of 10% (factory default). Rather than change the quantity of wire every time you take it off, you can change the multiplier to 1.15. Make the same change for each type of wire. Go through each conduit Catalog – PVC, GRC, etc. – and make the changes there as well, then change the Item Library (1) to Devices Flush and repeat the process. Do the same for each Item Library that deals with branch wire. Even though Item Library Feeders has a Catalog that says EMT, you won’t need to make changes there because a different way of calculating the wire length is being used.
Once you’ve made these changes, you will no longer need to add that additional 5% manually every time you take off your branch wire.
