Industrial engineers find ways to eliminate wastefulness in production processes. They devise efficient ways to use workers, machines, materials, information, and energy to make a product or provide a service.
Industrial engineers typically do the following:
Industrial engineers apply their skills to many different situations from manufacturing to business administration. For example, they design systems for
In all these different projects, industrial engineers focus on how get the work done most efficiently, balancing many factors--such as time, number of workers needed, actions workers need to take, achieving the end with no errors, technology that is available, workers' safety, environmental concerns, and cost.
To find ways to reduce waste and improve performance, industrial engineers first study product requirements carefully. Then they use mathematical methods and models to design manufacturing and information systems to meet those requirements most efficiently.
Forensic science technicians help investigate crimes by collecting and analyzing physical evidence. Most technicians specialize in either crime scene investigation or laboratory analysis.
At crime scenes, forensic science technicians, also known as crime scene investigators, typically do the following:
Crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence. In addition to processing crime scenes, they may also attend autopsies.
In laboratories, forensic science technicians typically do the following:
Forensic science technicians reconstruct crime scenes by carefully studying information gathered by investigators and conducting scientific tests on physical evidence. For example, lab technicians may look at photographs of blood splatter patterns and conduct ballistics tests on bullets found at the crime scene to determine the direction from which a shot was fired.
Forensic science technicians who work in laboratories use chemicals and laboratory equipment such as microscopes when analyzing evidence. They also use computer databases to examine fingerprints, DNA, and other evidence collected at crime scenes in order to match them to people and things that have already been identified. Most forensic science technicians who perform laboratory analysis specialize in a specific type of evidence analysis, such as DNA or ballistics.
All forensic science technicians prepare written reports that detail their findings and investigative methods. They must be able to explain their reports to lawyers, detectives, and other law enforcement officials. In addition, forensic science technicians may be called to testify in court about their findings and methods.
Civil engineering technicians help civil engineers plan and design the construction of highways, bridges, utilities, and other major infrastructure projects. They also help with commercial, residential, and land development.
Civil engineering technicians typically do the following:
Civil engineering technicians must work under the direction of a licensed civil engineer. For more information, see the profile on civil engineers.
Civil engineering technicians generally help civil engineers, often doing many of the same tasks as the engineers. However, because they are not licensed, civil engineering technicians cannot approve designs or supervise the overall project.
These technicians sometimes estimate construction costs and specify the materials to be used. Other times, they prepare drawings or survey land. Civil engineering technicians may also set up and monitor various instruments for studies of traffic conditions.
Civil engineers design and supervise large construction projects, including roads, buildings, airports, tunnels, dams, bridges, and systems for water supply and sewage treatment.
Civil engineers typically do the following:
Many civil engineers hold supervisory or administrative positions ranging from supervisor of a construction site to city engineer. Others work in design, construction, research, and teaching. They work with others on projects and may be assisted by civil engineering technicians and technologists.
The federal government employs about 12,100 civil engineers to do many of the same things done in private industry, except that the federally employed civil engineers may also inspect projects to be sure that they comply with regulations.
Civil engineers work on complex projects, so they usually specialize in one of several areas.
Geotechnical engineers work to make sure that foundations are solid. They focus on how structures built by civil engineers, such as buildings and tunnels, interact with the earth (including soil and rock). Additionally, they design and plan for slopes, retaining walls, and tunnels.
Structural engineers design and assess major projects, such as bridges or dams, to ensure their strength and durability.
Transportation engineers plan and design everyday systems, such as streets and highways, but they also plan larger projects, such as airports, ports, and harbors.
Electrical engineers design, develop, test, and supervise the manufacturing of electrical equipment such as electric motors, radar and navigation systems, communications systems, or power generation equipment. Electrical engineers also design the electrical systems of automobiles and aircraft.
Electronics engineers design and develop electronic equipment such as broadcast and communications systems, from portable music players to global positioning systems (GPS). Many also work in areas closely related to computer hardware.
Electrical engineers typically do the following:
Electronics engineers typically do the following:
Electronics engineers who work for the federal government research, develop, and evaluate electronic devices used in diverse technologies, such as aviation, computing, transportation, and manufacturing. They work on federal electronic devices and systems, including satellites, flight systems, radar and sonar systems, and communications systems.
The work of electrical engineers and electronics engineers is often similar. Both use engineering and design software and equipment to do engineering tasks. Both types of engineers must also work with other engineers to discuss existing products and possibilities for engineering projects.
Engineers whose work is related exclusively to computer hardware are considered computer hardware engineers. For more information about this occupation, see the profile on computer hardware engineers.
