• Review drawings, specifications, BIM models, and design documentation to quantify and estimate mechanical systems.
• Prepare quantity takeoffs for HVAC systems, process piping, utility infrastructure, process cooling water systems, and related mechanical equipment.
• Partner with engineering, design, procurement, and construction teams to evaluate design changes and cost impacts.
• Review and validate contractor and subcontractor estimates, pricing proposals, and bid submissions.
• Lead estimate reconciliation meetings and support alignment between project stakeholders.
• Evaluate and negotiate change orders while maintaining accurate change management documentation.
• Support cost management activities, including cost reporting, forecasting, contingency tracking, and budget monitoring.
• Develop benchmark data, unit rates, productivity assumptions, and historical cost databases to support estimating accuracy.
• Monitor labor markets, material pricing trends, and supply chain risks that may impact project costs.
• Provide value engineering support and recommend cost-effective design and construction solutions.
• Prepare estimate narratives, executive summaries, and client-facing presentations.
• Support procurement activities by reviewing bid packages and evaluating commercial proposals.
• Collaborate with project controls and cost management teams to maintain cost certainty throughout the project lifecycle.
• Mentor junior estimators and contribute to best practices across the estimating function.
• SOX control responsibilities may form part of this role and must be adhered to where applicable.

• Bachelor's degree in Construction Management, Quantity Surveying, Engineering, or a related discipline, or equivalent industry experience.
• 7+ years of mechanical estimating, quantity surveying, cost management, or commercial management experience within the construction industry.
• Experience supporting large-scale industrial, manufacturing, advanced technology, semiconductor, pharmaceutical, data center, or other complex construction projects.
• Strong knowledge of mechanical building systems, including HVAC, chilled water, process piping, utility infrastructure, mechanical equipment, and related systems.
• Demonstrated experience preparing estimates, quantity takeoffs, cost plans, change order evaluations, forecasting, and cost analysis throughout the project lifecycle.
• Experience reviewing contractor pricing, subcontractor proposals, procurement packages, and commercial change requests.
• Proficiency with estimating and quantity takeoff software such as Bluebeam, PlanSwift, CostX, OST, or similar platforms, along with advanced Microsoft Excel skills.
• Strong analytical, communication, stakeholder management, and problem-solving skills with the ability to work effectively in a fast-paced project environment.
