Bottoms-Up Estimating: Perform detailed time-to-task, workload-based, and resource-driven estimating to develop independent cost estimates, validate staffing model outputs, challenge assumptions, and support unique proposal requirements not adequately addressed by existing estimating models. Cross-Functional Coordination: Collaborate with project leadership, site personnel, maintenance managers, and functional subject matter experts to collect, validate, and reconcile labor and non-labor takeoffs supporting proposal development.
