Design and oversee construction and repair of marine craft and floating structures such as ships, barges, tugs, dredges, submarines, torpedoes, floats, and buoys. They confer with marine engineers.

Design or oversee projects involving provision of potable water, disposal of wastewater and sewage, or prevention of flood related damage. They prepare environmental documentation for water resources, regulatory program compliance, data management and analysis, and field work. They perform hydraulic modeling and pipeline design.

Develop plans for surface transportation projects, according to established engineering standards and state or federal construction policy. They prepare designs, specifications, or estimates for transportation facilities. They plan modifications of existing streets, highways, or freeways to improve traffic flow.

Perform engineering duties in planning, designing, and overseeing construction and maintenance of building structures, and facilities. They work on roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, power plants, and water and sewage systems

Design chemical plant equipment and devise processes for manufacturing chemicals and products, such as gasoline, synthetic rubber, plastics, detergents, cement, paper, and pulp, by applying principles and technology of chemistry, physics, and engineering.

Measure large areas of the earth's surface using satellite observations, global navigation satellite systems (gnss), light detection and ranging (lidar), or related sources.

Make exact measurements and determine property boundaries. They provide data relevant to the shape, contour, gravitation, location, elevation, or dimension of land or land features on or near the earth's surface for engineering, mapmaking, mining, land evaluation, construction, and other purposes.

Apply standardized mathematical formulas, principles, and methodology to technological problems in engineering and physical sciences in relation to specific industrial and research objectives, processes, equipment, and products.

Develop and apply biostatistical theory and methods to the study of life sciences.

Develop or apply mathematical or statistical theory and methods to collect, organize, interpret, and summarize numerical data to provide usable information. They specialize in fields such as bio statistics, agricultural statistics, business statistics, or economic statistics. Includes mathematical and survey statisticians.
