NES Fircroft is a leading global workforce solutions provider specializing in engineering and technical talent across the energy and industrial sectors. We partner with organizations delivering critical projects worldwide, connecting exceptional professionals with opportunities that drive innovation and operational excellence.

Our client, a leading midstream engineering and construction organization, is seeking a Senior Estimator – Pipelines/ Facilities to lead the development of detailed and competitive estimates for midstream pipeline, facility, terminal, and mechanical construction projects. This is a permanent, full-time opportunity based onsite in Evans, CO.

This is an excellent opportunity for an experienced mechanical estimator with a strong background in midstream oil and gas construction to take ownership of complex estimating activities across pipeline, facility, terminal, and mechanical projects.

The successful candidate will play a key role in developing accurate, competitive, and executable project estimates, bringing together technical expertise, commercial awareness, and an understanding of field construction methods to support successful project delivery.

Reporting to the estimating leadership team, the Senior Estimator will independently develop detailed mechanical and pipeline estimates, from initial bid review through proposal submission and project handover. This individual will serve as the primary technical estimating resource for piping, welding, equipment installation, and facility-related scopes.

• Develop comprehensive mechanical and pipeline estimates using engineering drawings, specifications, and bid documentation.
• Perform detailed material and labor takeoffs covering piping, welding, equipment, valves, structural components, and associated mechanical systems.
• Interpret P&IDs, piping isometrics, mechanical drawings, and construction specifications to identify scope gaps, quantity discrepancies, and constructability challenges.
• Develop labor build-ups using production rates, crew compositions, craft hours, historical data, and field productivity benchmarks.
• Coordinate with Supply Chain to solicit, evaluate, and normalize vendor and subcontractor quotations.
• Participate in pre-bid meetings and site visits to evaluate project conditions, execution requirements, and potential risks.
• Identify estimating assumptions, exclusions, commercial risks, and scope clarifications for proposal development.
• Collaborate with Project Management, Engineering, and Field Operations to validate construction methodologies, installation approaches, and labor requirements.
• Support value engineering initiatives and alternative construction strategies to improve project competitiveness and execution.
• Prepare detailed estimate summaries, cost breakdowns, pricing schedules, and supporting documentation for internal review.
• Maintain estimating databases, unit rates, historical cost information, and production benchmarks.
• Develop conceptual, budgetary, and FEL-level estimates where required.
• Support project handover by providing clear estimate logic, quantities, assumptions, and cost documentation to execution teams.
• Coordinate with Project Controls to establish appropriate cost data, WBS structures, and cost codes for project setup and tracking.
• Manage multiple bids concurrently, communicate progress to leadership, and maintain organized, traceable estimating records.
• Provide technical guidance and mentorship to junior estimating team members.

• Minimum 5 years of estimating experience within the Midstream…
