The position can be remote.

Requirements

• BA/BS plus six years of relevant experience or demonstrated equivalency of experience and/or education.

Nice To Haves

• Bachelor’s degree in Civil, Mechanical, Electrical Engineering, or a related field, or equivalent relevant industry experience.
• Ten years of experience in Construction and or Estimating.
• Hands-on field experience or direct experience in construction trades.
• Practical understanding of construction means and methods gained through field exposure.
• Working knowledge across major construction divisions and trades, with the ability to validate estimate components prepared by others for quality control.
• Expert-level estimating knowledge in at least one discipline (e.g., civil, structural, mechanical, electrical, or specialty trades).
• Experience estimating large-scale transportation, infrastructure, or complex federal programs.
• Familiarity with multiple estimating formats and classification systems (e.g., CSI, UniFormat).
• Strong written and verbal communication skills.
• High attention to detail and strong organizational skills.
• Ability to work on Federal and Military projects and meet background check and clearance requirements.

Responsibilities

• Lead and prepare construction cost estimates from conceptual design through bid-level documents.
• Develop high-level conceptual and schematic estimates based on limited or incomplete design information.
• Prepare detailed, bottoms-up estimates incorporating production-based labor, material unit costs, equipment costs, crew compositions, defined production rates, and fully built-up unit pricing.
• Develop estimates grounded in construction means and methods rather than reliance on historical unit costs alone.
• Solicit, review, and evaluate subcontractor and vendor pricing in support of detailed estimates and bid submissions.
• Develop, review, and reconcile change order and modification estimates.
• Perform cost reconciliations between internal estimates, subcontractor pricing, contractor bids, and third-party or independent estimates.
• Interface directly with clients, owners, subcontractors, and project teams to review estimates, resolve cost issues, and support cost-related decision-making.
• Provide quality control review of estimates prepared by other estimators across all trades.
• Utilize and adapt existing cost databases, historical data, workbooks, and estimating software.
• Independently manage assigned estimates while coordinating with support estimators.
• Review drawings, specifications, and scope narratives to identify risks, gaps, and constructability concerns.
• Clearly document estimate assumptions, exclusions, methodologies, and areas of uncertainty.
• Support value engineering, risk assessment, and cost optimization efforts.
• Support construction scheduling efforts by developing detailed, man-hour-based labor estimates to support resource-loaded schedules.
