Overview

The Senior Mechanical Estimator develops accurate mechanical estimates for piping, mechanical, welding, equipment setting, and facility work in the Oil & Gas industry. This role involves reviewing bid documents, conducting material and labor takeoffs, and preparing proposals while managing multiple bids and mentoring junior estimators.

Responsibilities

• Develop complete and accurate mechanical estimates from drawings, specifications, and bid documents.
• Perform detailed takeoffs for piping, welding, equipment, valves, structural components, and mechanical systems.
• Analyze drawings for constructability issues, scope gaps, and quantity discrepancies.
• Prepare labor build-ups using production rates, craft hours, crew compositions, and historical data.
• Utilize Supply Chain to solicit, evaluate, and normalize vendor and subcontractor quotes.
• Attend pre-bid meetings and job walks to assess site conditions and risks.
• Identify risks, assumptions, exclusions, and prepare proposal clarifications.
• Coordinate with project managers, engineering, and field teams to validate installation methods and labor assumptions.
• Support 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.
• Support conceptual, budgetary, and FEL-level estimates as needed.
• Provide complete estimate logic, quantities, and assumptions during project handoff.
• Supply Project Controls with required cost data for accurate job setup and tracking.
• Manage multiple bids and communicate status updates to leadership.
• Ensure estimate files, calculations, and supporting documents are organized and traceable.

Requirements

• 5+ years estimating experience in the Midstream Oil & Gas industry.
• Proficiency in mechanical takeoff methods for piping, welding, equipment, and structural components.
• 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.
• Proficiency in estimating software (InEight, HeavyBid, Navisworks, Bluebeam or similar).
• Advanced Excel skills (formulas, lookups, pivot tables, cost modeling).
• Knowledge of mechanical construction means and methods, including rigging, equipment installation, hydrotesting, and commissioning.
• Familiarity with ASME, API, and mechanical construction specifications.
• Ability to identify constructability challenges and productivity impacts.
• Understanding indirect costs, equipment rates, consumables, and labor burdens.
• Experience developing conceptual and budgetary estimates with limited information.
• Knowledge of WBS structures, cost codes, and estimate organization for project controls.
• Ability to support schedule alignment and communicate installation durations.
• Ability to apply lessons learned, historical costs, and field production data.
• Bachelor’s degree in construction management, Engineering, or related field preferred.
• Equivalent field experience or 5–10 years in a similar estimating role accepted.
• Professional certifications such as AACEI CEP, PMP, or ASPE preferred.

Additional Information

• Occasional travel required.
• Compliance with all company policies, including Drug & Alcohol policy.
• Ability to work safely and collaboratively.
• Must be authorized to work in the United States.
