Senior Project Estimator

  • Nisource, Inc.
  • Merrillville, Indiana
  • Full Time
Essential Functions

  • Leads development of Class 5-Class 1 cost estimates for gas infrastructure projects, including pipelines, facilities, regulator stations, and related assets.

  • Establishes and maintains estimating standards, tools, benchmarks, and methodologies for major gas projects to ensure consistency and alignment with organizational processes.

  • Partners with Engineering and Gas Operations to translate project scope (pipe diameter, materials, station design, HDD/boring, restoration, etc.) into quantifiable cost drivers .

  • Integrates risk-based estimating practices , including contingency, escalation, and probabilistic analysis, reflecting gas-specific construction risks (ROW constraints, permitting, constructability, subsurface conditions).

  • Supports project gating and capital planning by providing validated estimates, cost ranges, and confidence levels aligned with funding decisions.

  • Coordinates with Engineering, Supply Chain, and Construction to validate labor productivity, material pricing , contractor rates, and installation assumptions.

  • Performs estimate reconciliation and benchmarking against historical gas project data to identify trends, variances, and improvement opportunities.

  • Develops and maintains gas-specific cost models, unit rates, and parametric tools for early-stage screening and portfolio prioritization.

  • Supports procurement by preparing Independent Cost Estimates (ICEs) and participating in bid evaluations to ensure competitive pricing.

  • Partners with Project Managers to transition estimates into executable project budgets , ensuring alignment with construction strategies and assumptions.

  • Applies cost-control principles to support variance analysis, change management, and forecasting for gas capital projects.

  • Communicates estimate basis, assumptions, risks, and confidence levels clearly to stakeholders, including leadership and governance bodies.

  • Ensures all estimating activities reflect gas safety, environmental, and regulatory requirements , including constructability and compliance considerations.

Required Qualifications

  • Bachelor's degree in Engineering, Construction Management, or related field; or equivalent experience (minimum 10 years) .

  • 7-10 years of experience in cost estimating, cost engineering, or project controls within gas utilities or similar infrastructure sectors.

  • Demonstrated experience developing multi-discipline estimates for gas capital projects (pipelines, facilities, stations).

  • Advanced proficiency in Excel and estimating tools, including large, complex models and datasets.

  • Hands-on ability to build, manipulate, and validate detailed cost models , including formulas, data structuring, and scenario analysis.

  • Ability to operate at the intersection of financial modeling and construction estimating , translating field-driven scope into structured outputs.

  • Working knowledge of CBS, WBS , and gas project estimating classifications.

  • Experience applying risk-adjusted estimating and contingency methodologies.

  • Ability to develop defensible estimates under tight timelines , with clear documentation.

  • Strong presentation skills with the ability to communicate assumptions, risks, and outputs to senior leadership.

  • Comfortable presenting in formal review settings and defending estimate positions.

  • Strong verbal communication skills with the ability to simplify complex estimating concepts for non-technical audiences.

  • Ability to work under stringent deadlines and manage competing priorities.

  • Ability to travel up to 25% for project site visits.

  • Valid motor vehicle operator's license.

Preferred Qualifications

  • Experience in regulated gas utility environments and large-scale capital programs.

  • Professional certifications such as CCP , AACEI , or PMP .

  • Experience supporting capital planning, portfolio prioritization , or regulatory filings for gas projects.

  • Working knowledge of PHMSA regulations , state utility requirements, permitting, and safety standards.

Physical Demands

  • Ability to work in field environments supporting gas construction and estimating validation activities.

  • Must be able to work in areas of high noise, dust, extreme temperatures, confined spaces, and potential exposure to chemical hazards.

  • Ability to walk project sites, including uneven terrain and active construction areas, as needed to validate estimating assumptions.

  • Must be able to drive to and access multiple project locations.

  • Ability to sit for extended periods while performing analytical and computer-based estimating work.
