• Understand project scope, specifications and design criteria for assigned projects
• Provide on-site assistance during startup.
• Support engineering activities such as stress analysis, construction specifications, material procurement specifications, calculations and piping estimates.
• Develop conceptual layouts and cost studies as necessary to determine the simplest, most efficient approach to solving engineering tasks at hand.
• Produce estimate level preliminary designs and material take-offs suitable for the level of the estimate being performed on a project.
• Produce detail design calculations and sketches for materials of construction associated with the project.
• Assist the drafting group in resolving routine layout and detailing problems.
• Consult with design leaders from other disciplines.
• Review and check vendor drawings and other discipline drawings for mechanical input.
• Produce designs with efficient use of construction materials with an overall emphasis on ease of construction and completed product meeting the expectations of the client.
• Check calculations made by other engineers to ensure accuracy, conformance to codes, specifications, design criteria and conformance to good engineering practice.
• Advise the senior engineer concerning design or scope changes, which have been identified.
• Assist other engineers in developing and assembling scopes, drawings and specifications into a "package", enabling mechanical purchase inquiries to be issued for procurement of equipment, materials or subcontract pricing.
• Develop construction specifications.
