Sigma Estimates

Sigma Estimates is an incredibly brilliant, highly strategic European-born titan that achieved massive success through an ingenious psychological design: "The Excel Illusion." The absolute hardest part of getting an estimator to use new software is that they are deeply, emotionally addicted to Microsoft Excel. Sigma's user interface is explicitly engineered to look, feel, and function exactly like an Excel spreadsheet, while secretly possessing a massive, relational SQL database underneath. Its signature feature is "The 5D BIM (Building Information Modeling) Integration." While it looks like Excel, it is technologically terrifying. An estimator can natively link a line item in Sigma directly to a 3D object in Autodesk Revit. If the architect makes the 3D building 10 feet taller in Revit, Sigma mathematically detects the change, automatically recalculates the brick quantity, and instantly updates the "Excel" spreadsheet cost in real-time. Because it bridges the gap between old-school spreadsheets and modern databases, its "Structure and Validation" is unmatched. In a massive Excel file with 5,000 rows, one broken formula (a missing equals sign) can result in a $1 million bidding error. Sigma mathematically protects the data structure. You get the speed of typing in Excel, but the software mathematically guarantees that the sub-totals roll up flawlessly to the top line without terrifying formula breaks.
