Case Study: Blach Construction achieves doubled estimating output and streamlined real-time collaboration with ProEst

How ProEst helped improve estimating collaboration and workflow

Blach Construction, a northern California commercial builder, had long been hampered by “old, clunky” estimating platforms that lacked speed, stability and real-time collaboration. In 2018 they selected ProEst’s cloud-based estimating solution to provide a more modern, user-friendly system that would improve templates, database access and team workflow.

ProEst’s implementation delivered immediate improvements in ease-of-use, shareability and embedded task features, plus in-person and video training that sped adoption. As a result Blach doubled its estimate output (from 60 to 120 in one year), prepared 120+ estimates last year and achieved $300M+ in revenue with growth targets of $400–$500M, demonstrating clear, measurable productivity gains from ProEst.
