• Participate in pre-proposal design coordination meetings to support the development of pricing documents for conceptual estimates.
• Perform constructability analysis of project documents. Communicate design and constructability issues to the project team, while identifying risk elements and appropriate mitigation measures.
• Provide viable design alternatives and value engineering propositions with analysis supporting benefits to initial and life cycle cost, schedule, maintenance, etc.
• Perform quantity survey of mechanical systems and components using digitized software, and apply industry standard labor rates (e.g., MCAA, PHCC, etc.) to develop accurate cost estimates.
• Evaluate vendor and subcontractor for conformance with proposal requirements; level scopes and identify low cost/ best value responses while capturing assumptions, rationale, inclusions, exclusions, etc.
• Prepare estimates used for bidding and budgeting purposes (including self-performed work); participate in internal estimate review process and assist with final recap of estimate for presentation to senior management.
• Support project management tasks, including budgeting, schedule development, interim design review, change order pricing, procurement, value engineering, and vendor selection based on proposal development.
• Coordinate with project teams to evaluate productivity for historical data and schedule/ cost forecasting purposes.
