Job Summary
The Estimator I develops assigned estimate components and scopes under defined direction while learning Loenbro estimating standards, systems, and cost-development methods. This role performs quantity takeoffs, compiles pricing, organizes quotations, identifies scope concerns, and maintains complete estimate documentation. Project value is a planning guide rather than a classification gate; assignment complexity, risk, scope definition, and required independence govern the work assigned.

Essential Job Responsibilities

  • Perform quantity takeoffs and develop assigned scope in accordance with bid documents and work breakdown requirements.
  • Compile labor, material, equipment, subcontract, and indirect-cost inputs using approved sources and methods.
  • Solicit and organize vendor and subcontractor quotations; document coverage, qualifications, and missing information.
  • Identify scope gaps, design discrepancies, commercial concerns, and project risks for senior review.
  • Maintain estimate files, assumptions, clarifications, exclusions, and supporting documentation.
  • Meet assigned deadlines and participate in estimate reviews, site visits, pre-bid meetings, and turnover activities.
  • Use approved estimating, takeoff, CRM, and document-management systems accurately.
  • Apply review feedback and demonstrate measurable growth toward independent estimate execution.

Minimum Qualifications

Required:

  • 0–2 years of relevant estimating, construction, engineering, field, or related technical experience; entry-level candidates with applicable education or training may be considered.
  • Foundational knowledge of mechanical, structural, and light civil construction, including construction documents, quantities, labor, materials, and equipment.
  • Experience or developing knowledge in self-perform estimating, including labor, materials, equipment, production rates, and crew requirements.
  • Ability to read and interpret construction drawings and specifications related to:
    • Concrete and structural construction
    • Structural steel installation
    • Process piping
    • Process engineering and related industrial systems
    • Light civil/site work
  • Ability to perform accurate quantity takeoffs and develop estimates for self-performed scopes.
  • Ability to communicate clearly, organize information, collaborate with project teams, and meet deadlines.
  • Proficiency with Microsoft Office and ability to learn required estimating, takeoff, CRM, and document-management systems.
  • Ability to travel periodically to offices, client locations, and project sites.
  • Valid driver’s license and insurability when driving is required.

Preferred:

  • Associate or bachelor’s degree in construction management, engineering, or a related field, or equivalent experience.
  • Experience with Accubid, HeavyBid, Salesforce, PlanSwift, Bluebeam, or comparable systems.

Potential Hazards:

  • Potential exposure to extreme cold and hot temperatures
  • Exposure to manufacturing, pipeline, and refining environment
  • Exposure to noise above 85 decibels and intense odors
  • Exposure to areas with limited visibility

Physical Demands and Work Environment

  • Climbing up and down stairs and ladders to both get in and out of trenches and up to elevated platforms, including scaffolding at significant heights
  • Lifting necessary equipment and materials 1–50 pounds, 50% of the time on a monthly basis for required tasks
  • Potential or periodic requirements may include the following:
    • Walking on uneven terrain, with an average of 2 miles per day
    • Standing
    • Sitting, stooping, crawling, and kneeling
    • Use of respirator if position requires
    • Driving if required to travel
  • If driving is required, a valid driver’s license and proof of insurability are required. All drivers are subject to a DMV background records search.
