This is mechanical engineering work at the full performance level applying engineering knowledge to the design and/or installation of mechanical equipment in a variety of public works. Work includes the preparation of designs, plans, specifications and estimates for small design projects, the design of the more difficult phases of a major project, or the inspection for installation and/or maintenance purposes, of major mechanical equipment. Work differs from the next lower class in that the assignments received define the scope of the work but the employee uses independent judgment in planning work details and making technical decisions. Establishing and maintaining effective work relationships with contractors, consultants and fellow employees is a significant aspect of the work.

Work is performed under the general supervision of an engineering superior. Assignments require analytical thinking and are performed in accordance with accepted engineering standards and applicable regulations. Employees in this class work with engineers, contractors and others to complete assigned engineering projects.

• Designs the more complex phases of a major project for a variety of mechanical equipment installations such as heating, ventilating, air-conditioning, and power systems, electrostatic precipitators, waste water or raw water pumping station and incinerator plant systems; makes difficult engineering computations; prepares plans for the installation of complex mechanical equipment; prepares plans and specifications including detailed cost estimates; makes field trips to secure data to be used in preparing plans and specifications; prepares quantity lists of mechanical equipment and materials necessary for various projects; prepares reports and recommendations on various phases of mechanical engineering problems.
• Inspects installation or major alterations to mechanical equipment performed by private contractors to insure compliance with plans and specifications; approves minor variations to plans when field conditions warrant; may recommend halting construction when major instances of non-compliance are noted; reviews contractors' proposed work schedules to assure the proper sequence of installation; maintains records of work and shop drawing to determine adherence to work schedules; prepares periodic work progress reports.
• Reviews mechanical phases of plans and specifications prepared by engineers to determine accuracy and completeness of plans; checks contractors' shop drawings for compliance with technical standards and specifications; explains and interprets specifications and requirements and refers more complex problems to superior.
• May give assignments to, and supervise the work of a small number of engineers, engineering technicians and engineering aides engaged in the preparation of designs, plans, estimates and drawings or other related assignments.
• Performs related work as required.

KNOWLEDGE OF:

• the principles and practices of mechanical engineering as applied to the design, installation and operation of mechanical equipment.
• engineering mathematics and mathematical tables used in mechanical engineering.
• characteristics of materials as they relate to the mechanical engineering phases of construction projects.
• the techniques used to prepare and compose technical reports, letters and memoranda.

ABILITY TO:

• apply mechanical engineering knowledge to the design, installation and operation of mechanical equipment as well as analyze poor performance of such equipment and make recommendations for correction and/or replacement.
• prepare complete contract plans, specifications and cost estimates for a major phase of mechanical design projects involving the substantial adaptation and modification of mechanical systems and equipment.
• obtain field information and data necessary for the design of complex mechanical equipment.
• review and interpret designs, specifications and cost estimates for mechanical engineering projects and to obtain contractor conformance to established standards.
• check contractors' shop drawings of difficult equipment fabrications and installations for conformance to departmental design specifications, and to make necessary corrections.
• assure compatibility of new mechanical systems and equipment with the remainder of design package and/or existing plant facilities.
• assign and supervise the work of engineers, engineering technicians and engineering aides.
• interpret regulations affecting the work.
• establish and maintain effective working relationships with associates, contractors and the general public.

• Completion of a bachelor's degree program at an accredited college or university with major course work in mechanical engineering.
• Two years of mechanical engineering experience in the design and installation of mechanical equipment common to public works, structures and installations.

Or any equivalent combination of acceptable training and experience that has included the completion of a bachelor's degree program in an acceptable area of engineering as an educational minimum.

PHYSICAL AND MEDICAL REQUIREMENTS
