Job description

MATRIX is seeking a highly skilled and experienced Sr. Mechanical Estimator to join our dynamic team. In this position, the Sr. Mechanical Estimator will bring with them strong experience estimating nuclear construction, modification, and installation projects, particularly mechanical equipment and piping systems. This role requires a practical understanding of craft execution, construction sequencing, and the conditions that affect labor productivity in a nuclear facility. The selected professional will develop detailed, defensible estimates that reflect the technical scope, field conditions, and applicable nuclear quality and documentation requirements.

DURATION: 12 months +

WORK SCHEDULE: 40 - 50 hours per week, likely Monday through Friday

PER DIEM: Yes, if eligible

LOCATION: Hybrid role with Travel to Charlotte, NC

ESSENTIAL FUNCTIONS & RESPONSIBLITIES:

• Develop detailed mechanical and piping construction estimates, including craft labor hours, materials, equipment, subcontractor costs, and other project execution costs.
• Review drawings, specifications, work packages, and scope documents to establish estimating requirements and identify gaps or uncertainties.
• Perform quantity takeoffs for piping, fittings, valves, supports, mechanical equipment, and associated installation activities.
• Estimate craft labor for equipment installation, piping fabrication and installation, welding, rigging, testing, and related mechanical work.
• Account for nuclear site conditions that affect execution and productivity, including access restrictions, radiological controls, work windows, congestion, and outage schedules.
• Incorporate applicable quality requirements, inspections, nondestructive examination, testing, and turnover documentation into estimates.
• Work with construction leaders, craft supervision, engineering, procurement, and project controls to validate execution plans, labor assumptions, and schedules.
• Evaluate vendor and subcontractor quotations for scope completeness and alignment with project requirements.
• Prepare estimate assumptions, exclusions, clarifications, and supporting documentation for internal review and proposal development.
• Support scope changes and estimate revisions, and use available actual cost and productivity data to improve future estimates.
• Perform primarily office and non-manual work.
• Perform work related to the management or general business operations of MATRIX or its customers/clients, while exercising discretion and independent judgment with respect to matters of significance to MATRIX and its customers/clients.
• Interface with managers or head of a unit/department requiring the integration of multiple functional organizations.
• Use “lessons learned” to improve quality of MATRIX’s future projects; make recommendations to MATRIX as to the implementations of future policies and procedures.

Required Qualifications

• Significant experience developing detailed estimates for mechanical and piping construction projects, including direct experience in nuclear facilities.
• Strong understanding of nuclear construction and modification work, with particular emphasis on craft labor requirements and field execution.
• Demonstrated ability to estimate labor hours and productivity based on installation methods, work sequencing, site constraints, and project conditions.
• Ability to interpret mechanical drawings, piping isometrics, P&IDs, equipment specifications, and construction scope documents.
• Working knowledge of piping fabrication, welding, supports, mechanical equipment installation, rigging, inspection, and testing.
• Familiarity with nuclear quality assurance, work control, and documentation requirements as they affect construction scope and cost.
• Proficiency with estimating tools and Microsoft Excel, with the ability to clearly document and explain the basis of an estimate.
• Strong attention to detail and ability to coordinate with engineering, construction, procurement, and project controls teams
• The ability to communicate well both verbally and written as a business necessity to ensure the safe and efficient operations of business. Clear, concise, and effective fluency in the English language is essential

Preferred Qualifications

• Prior experience supporting nuclear outages, major plant modifications, or new nuclear construction.
• Previous mechanical or piping craft, field supervision, or construction management experience.
• Familiarity with applicable ASME codes and nuclear mechanical and piping requirements.
• Experience reconciling estimates against actual field costs and craft productivity.
• Proficiency with Hard Dollar / N8 estimating software.

Special Requirements

• Availability for travel and site visits as required.
• Ability to meet applicable client and nuclear site access requirements.
