Job Summary

The Estimator III leads complex pursuits and major scopes with minimal supervision while providing advanced technical judgment, quality control, and development support to the estimating team. This role integrates work packages, leads risk and constructability analysis, directs quotation strategy, and coordinates estimate decisions with key stakeholders. A typical project-value guide is up to approximately $50 million, but complexity, risk, delivery method, scope integration, and required independence govern assignment.
