Customers Testimonials

With Sigma implemented across all countries, our design and development teams will get a digital estimation workflow, with everyone having instant access to updated data. In addition, the production managers will gain a better financial overview throughout the entire construction process because data can now flow freely between Sigma and our other systems

Global Head of VDC, Bonava

Sigma is a fast, flexible and precise tool in contrast to, for example, a spreadsheet. It is possible to reuse actual data from previous projects, and there is a direct link to the standard local cost databases, like RSMeans, ÅF or Molio.

If I had to be doing math all day, it would make my job a whole lot harder. It’s much easier when the math is already done. You just have input the dimensions and then it does the calculations. Hourly wages, material costs, and any carpentry costs with the markup for whatever job you’re doing, and it puts it all together

How Sigma Works for General Contractors

With Sigma, you can estimate construction projects in the same logical way you would build them.  Estimates for each building section are created separately, and the project is automatically summarized on the built-in Summary sheet, giving you an overview of the entire project, without you having to write as much as a single formula.

1. Specify your Building Structure

You start your estimate by specifying the building structure, for example by entering the dimensions of a floor, roofing section or wall etc. Sigma gives you an overview, so you can check you have included all the parts required, and then material quantities can be pulled in using our Sigma’s Sigma + Planswift Live 2D Takeoff, uploading a data file or manually entering quantities.


2. Adding Cost Data

Now you can add your cost data to  each section in your building structure With Sigma, you can add your cost data by connecting to premium cost books using our integration, upload your Excel file or enter the cost data you’ve memorized by manually entering. The data will be the same methodical way as you would if you were building it.  This logical workflow and flexible system, gives you confidence that nothing is missing, and in turn saves you hours of work.

3. Link Material Quantities

It’s now time to update your takeoff quantites based on your site plans. You have many options – including Sigma & Planswifts’ Live Link integration where you can run takeoff and add quantities inside your estimate — and it’s as simple as clickling your mouse. Sigma will automatically map your takeoff quantities to the correct sections, material, labor and resources. 

4. Review your Estimate

The Summary sheet summarizes material quantities, cost prices, profit margins and more. With all this information presented in one place, it is easy to give targeted discounts or adjust the project’s total amount to match a competitor’s price. This is all done without triggering an avalanche of manual recalculations because Sigma automatically updates all the numbers, right down to the individual building sections.

As you complete price and quantity details for individual building sections, the total price of the construction project is automatically summarized on the Summary sheet. From here you can drill back down into the pricing details for each section if you wish.


5. Easily Save, Print and Share

When the estimate is finalized, and the price agreed, you can save, print, attach and send the pricing summary, details, material supply requirements, notes, and other required documents all with the click of a button. This gives everyone on the project the information they need in the format they need it in.

6. Create Your own Cost Library

When you have finished and saved an estimate, you can reuse these estimates for new construction projects by importing building sections from an existing project into a new one. You do not need to update any formulas because Sigma does it for you – the only thing you need to change is the pricing and quantity.

In this way, you will gradually build your own database of estimates for building parts that you regularly use. Then you have them ready for the next construction project you need to estimate in Sigma.
