Estimating suite for construction costs

Be faster, more accurate, reliable and strategic from estimation to execution. Faithfully reproduce your calculation methods on a more solid, flexible and specially designed basis for estimation, compared to a spreadsheet like Excel.

Estimate your project costs.
Get an accurate list of materials to order.

Select a list of items to count.

Select the appropriate estimation template for the project. The template suggests item assemblies (e.g., floors, walls, roofs, etc.) to be selected as needed to ensure you don’t forget anything. When items are selected, related sub-items (e.g., materials, tasks, etc.) are entered automatically. You can customize, duplicate, and modify all templates based on the types of projects you do.

Enter or confirm the values ​​for each option.

In construction, everything can change. Enter or confirm the values ​​for each option (e.g., dimensions, choice of materials, etc.) in the item assemblies. Sub-items are calculated automatically (e.g., quantities, time, costs, etc.). You can also customize options and their values ​​to project templates based on your work habits in order to speed up the estimation process and reduce the risk of mistakes.

Shop around for better prices to reduce costs.

Have more time to shop around for prices and materials. Adjust prices, choices for each material and the choice of contractors during negotiations. Be in perfect control of your project throughout estimation, negotiation and completion.
