How does Obrarum use your library when you build a construction estimate?

  1. Type the item

    Type the item's name in your estimate and the library shows matches, so you don't hunt through a list.

  2. Pick a match

    Items from your library come first, with your price, then the templates from the Obrarum library. You choose which one to use.

  3. Add it with its breakdown

    The item goes into the estimate with its cost breakdown, so you never build it from scratch.

Frequently asked questions

Can I save my own prices and use them in every construction estimate?

Yes: save each item with its cost breakdown so you never work it out again. In Obrarum you keep it in your library with your prices and pick it when you build any estimate.

Is there a ready-made item library for estimating a construction job?

Yes, there are ready-to-use item libraries. The Obrarum library has 279 items in 15 categories for Latin America and 375 in 16 for the US and Canada, as templates with materials, labor and quantities, with no prices.

Does an item library come with material and labor prices?

It depends on the library: some include prices, but they change with the supplier and the city. The Obrarum library doesn't: you start from a template with its materials and quantities and add your own prices.

Does an item library work for jobs in Latin America, the US and Canada?

Yes, if it has a version for each market. In Obrarum, the Latin America one is in Spanish with metric units, and the US and Canada one is in English with imperial units. It shows you the one that matches the language you use.

Is there free software with an item library for construction estimates?

Yes. Obrarum has a Free plan that never expires and needs no card, with your library and the Obrarum library included.
