Estimate projects the same way you build them!

Imagine completing your estimates at a fraction of the time. Or, delivering your proposals and quotations painlessly with detailed insights and reporting capabilities for all project stakeholders. You can do all this and rid yourself of mind-numbing duplication by using Sigma.

Shorten your estimating
time by up to 85%!

With Sigma, you can estimate new construction projects rapidly because it lets you import and reuse entire building sections from existing projects.  This is much faster than writing complicated formulas in conventional spreadsheets, and it gives you an accurate overview of your project right from the start.

Eliminate estimating errors
and duplication

Sigma automatically reconfigures formulas when you import building sections from existing projects, and estimates for new building sections are easily and intuitively set up, making errors and omissions less likely.  As a bonus, you avoid duplicating your efforts re-writing estimates for the same part of the building.

“Whether you’re a small construction company with a few employees or you’re a large and growing business like Per Aarsleff, Sigma is the ideal construction project estimation software.”

Jesper Jacobsen Divisional Manager of Construction, Per Aarsleff


“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 or Molio”

Bo Grave Director of Digital Innovation, Ramboll


Estimate accurately – every time!

The accuracy of your estimates is improved because you can integrate with industry-leading pricing databases or reuse your own pricing information.  This means you can base your pricing decisions on market rates and your own historical data, reducing the risk of over- or underpricing.  Additionally, the Summary sheet gives you a clear overview, so you can quickly check that you have included everything you need.

Sigma is the estimating tool you have always wanted

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.

Sigma takes the difficulty out of setting up estimates and pricing proposals.  Instead of spending hours writing formulas that link through lots of tabs in a conventional spreadsheet, you can compile estimates of each building section separately, and automatically get a summary from the built-in Summary sheet.

Start with the structure

You start 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 from the drawings in the CAD program.

Add the detail of your estimates

You can then begin to add the pricing details and material quantities for each section, working in the same methodical way as you would if you were building it.  This logical workflow gives you confidence that nothing is missing, and saves you hours of work.

Review your estimates on the Summary sheet

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.

Easily make last-minute adjustments

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.

Provide everyone with the details they need

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.

Reuse existing estimates or build your own database

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.

Sigma makes your life so much easier.
