Case Study: O'Shea Builders achieves faster, more accurate cost estimating with Trimble WinEst and Modelogix
A Trimble Case Study
O’Shea Builders Establishes a Winning Cost Estimating Legacy with Trimble WinEst and Modelogix
O’Shea Builders, a Springfield, Illinois commercial general contractor founded in 1902, needed a standardized, integrated cost-estimating process to manage growth, improve accuracy and consistency, and better support clients. Company leaders charged new Chief Estimator Steve Ludwig with developing a cost-knowledge management system and estimating best practices to make estimates more reliable and comparable.
They implemented Trimble WinEst and Modelogix to build a centralized cost database with job codes, customizable assemblies, SpecVars, filters and an audit trail, enabling quick generation of client-formatted bid packages, rapid “what‑if” scenarios, error detection and faster estimator onboarding. The outcome: greater responsiveness, improved estimate accuracy and consistency, streamlined reviews, data-backed negotiations that won new work (e.g., Memorial Health), and scalable estimating practices across the team.
