The Mechanical Preconstruction Manager will participate in all aspects of the preconstruction process for mechanical systems to develop accurate, detailed cost estimates, often based on conceptual or schematic designs with a focus on heavy/ advanced manufacturing, industrial and mission critical projects. This role is expected to interact with engineers, architects, consultants, owner's representatives, subcontractors, suppliers, a multi-discipline estimating team, senior management, project supervision, and field personnel.

The Specifics of the Role

  • Responsible for the collection and distribution of bid documentation relative to RFPs, and solicitation for bid requests using online platform (Autodesk Building Connected).
  • Assist in gathering information to complete Bid Qualification and Criteria requirements.
  • Attend pre-bid meetings to become familiar with unique project requirements and analyze existing site conditions to determine required scope that is not already indicated.
  • Review and interpret project documents to determine job-specific material, equipment, and labor requirements for scope development.
  • Prepare written scopes of work for subcontracts and suppliers and coordinate mechanical scopes with the work of other trades (e.g., civil, structural, architectural, electrical, etc.).
  • 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.
  • Maintain and improve supplier and subcontractor database utilizing the company's prequalification program.
  • Supervise junior estimators, estimating assistants and/or Interns, providing training and support in a mentoring capacity and review work products for quality control.
  • Assist in the organization and maintenance of estimating software material cost databases to ensure accurate costs are consistently utilized on bids; communicate data on construction and material cost trends affecting project costs to project teams.
  • Identify opportunities for improvement in departmental processes, approach, and execution of estimating and preconstruction functions; assist in creating or adopting new tools to maximize productivity with the lowest attendant value of acceptable risk.

Requirements

  • Bachelor's Degree in Mechanical Engineering, or other Engineering discipline, Construction Management, or related field, or a combination of education (including trade schools) and professional experience.
  • 5-10 years of experience in preconstruction/estimating with a focus on mechanical systems (i.e., Fire Protection, HVAC, Plumbing, Piping).
  • Exhibits inclusive leadership and teamwork behavior, and values diverse perspectives from team members.
  • Demonstrated experience in the successful management of bidding process for conceptual estimates with a preferred emphasis on heavy/ advanced manufacturing, industrial and mission critical markets.
  • Working knowledge of codes and standards applicable to the design and installation of mechanical systems.
  • Working knowledge of construction contract language and terms in addition to various contractual delivery methods (e.g., negotiated, hard bid, design assist, GMP, etc.)
