Familiarity with project scope, specifications and design criteria upon assignment to a project task team.
On-site assistance during startup.
Accomplishing engineering activities such as stress analysis, construction specifications, material procurement specifications, calculations and piping estimates.
Developing conceptual layouts and cost studies as necessary to determine the simplest, most efficient approach to solving engineering tasks at hand.
Producing estimate level preliminary designs and material take-offs suitable for the level of the estimate being performed on a project.
Producing detail design calculations and sketches for materials of construction associated with the project. Calculations produced will be neatly prepared and organized for efficient checking by others and efficient use by drafters/designers for preparing drawings and as a deliverable when required.
Assisting the drafting group in resolving routine layout and detailing problems. Responsibilities include provision of sufficient sketches and details necessary for completion of engineering drawings.
Consulting with design leaders from other disciplines to ensure the smooth flow of vital information necessary for the scheduled completion of the project.
Reviewing and checking vendor drawings and other discipline drawings for mechanical input.
Producing designs with efficient use of construction materials with an overall emphasis on ease of construction and completed product meeting the expectations of the client.
Checking calculations made by other engineers to ensure accuracy, conformance to codes, specifications, design criteria and conformance to good engineering practice.
Advising the senior engineer concerning design or scope changes, which have been identified.
Assisting 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.
Developing construction specifications.
Reviewing fabrication drawings and other construction submittals for conformance to engineering drawings and specifications.
Performing fieldwork necessary to gather field data, check tie-ins and provide construction support.
Provide technical guidance to less experienced drafting and engineering personnel in the department.
