Case Study: T.K. Rubke & Co. achieves 90%+ project win rate with Sage Construction

T.K. Rubke & Company earns a project win rate of over 90%

T.K. Rubke & Company is a Georgia-based construction management firm that handles projects for major clients across the Southeast. The company needed fast, accurate, and defensible pre-construction estimates but found spreadsheets risky and error-prone, which threatened margins, credibility, and its ability to bid competitively and grow.

By adopting Sage Estimating (Sage Timberline) the firm standardized estimating with robust assembly databases and easy access to historical project costs, eliminating spreadsheet formula errors and speeding the bid process. The result: more accurate in-house estimates, a clear competitive advantage over firms that rely on contractor bids, a stronger recruiting pitch for new estimators, and a project win rate above 90%.
