Job Summary

The Sr. Specialist – Estimator independently develops accurate project scopes for crude oil gathering projects. The role involves interpreting drawings, validating constructability, identifying risks and scope gaps, and coordinating with internal teams to ensure accurate pricing and execution alignment. The Sr. Specialist manages multiple project scopes, maintains disciplined estimating practices, updates cost data, and supports handoff to project teams. The core objective is to deliver accurate estimates, reduce project risk, and help the company secure profitable, buildable work.

• Develop complete and accurate project estimates from conceptual scopes.
• Analyze conceptual scopes and drawings (if applicable) for potential scope gaps and constructability.
• Prepare labor build-ups using production rates, craft hours, crew compositions, and historical data.
• Identify risks, assumptions, exclusions, and prepare proposal clarifications.
• Coordinate with project managers, engineering, and field teams to validate installation methods and labor assumptions.
• Support added value engineering and alternative construction approaches.
• Prepare estimate summaries, cost breakdowns, and pricing sheets for internal review.
• Maintain cost data, unit rates, and historical production information.
• Provide complete estimate logic, quantities, and assumptions during project handoff.
• Manage multiple scopes and communicate status updates to leadership.
• Ensure estimate files, calculations, and supporting documents are organized and traceable.
• Thrive in a fast moving and competitive environment.

• Experience developing conceptual and budgetary estimates with limited information.
• Experience in Oil, Gas & Midstream industrial estimating and project management.
• Strong understanding of piping materials, pressure classes, fittings, and fabrication practices.
• Ability to develop detailed labor estimates using crew makeup and production rates.
• Skilled in reading P&IDs, isometrics, mechanical drawings, and scope documents.
• Experience with unit-rate, resource-based, and detailed line-item estimates.
