Landscape architects plan and design land areas for parks, recreational facilities, highways, airports, and other properties. Projects may include subdivisions and commercial, industrial, and residential sites.

Landscape architects typically do the following:

• Confer with clients, engineers, and building architects to understand a project
• Prepare site plans, specifications, and cost estimates
• Coordinate the arrangement of existing and proposed land features and structures
• Prepare graphic representations and drawings of proposed plans and designs
• Analyze environmental reports and data on land conditions, such as drainage
• Inspect landscape work to ensure that it adheres to original plans
• Approve the quality of work that others do
• Seek new work through marketing or by giving presentations

People enjoy attractively designed gardens, public parks, playgrounds, residential areas, college campuses, and golf courses. Landscape architects design these areas so that they are not only functional but also beautiful and harmonious with the natural environment.

Landscape architects plan the locations of buildings, roads, and walkways. They also plan where to plant flowers, shrubs, and trees. Landscape architects design and plan the restoration of natural places disturbed by humans, such as wetlands, stream corridors, and mined areas.

Many landscape architects specialize in a particular area, such as beautifying or otherwise improving streets and highways, waterfronts, parks and playgrounds, or shopping centers.

Increasingly, landscape architects are working in environmental remediation, such as preserving and restoring wetlands or managing storm-water runoff in new developments. They are also increasingly playing a role in preserving and restoring historic landscapes.

Landscape architects who work for government agencies do design sites and landscapes for government buildings, parks, and other public lands, as well as plan for landscapes and recreation areas in national parks and forests.

In addition, they prepare environmental impact statements and studies on environmental issues, such as planning for use of public lands.

Drafters use software to convert the designs of engineers and architects into technical drawings and plans. Workers in production and construction use these plans to build everything from microchips to skyscrapers.

Drafters typically do the following:

• Design and prepare plans for using computer-aided design and drafting (CADD) software
• Produce effective product designs by using their understanding of engineering and manufacturing techniques
• Add structural details to architectural plans from their knowledge of building techniques
• Prepare multiple versions of designs for review by engineers and architects
• Specify dimensions, materials, and procedures for new building projects or products
• Work under the supervision of engineers or architects

Many drafters are referred to as CADD operators. With CADD systems, drafters create and store drawings electronically so that they can be viewed, printed, or programmed directly into automated manufacturing systems. New software systems, such as building information modeling (BIM) and product data management (PDM), are coming into use. Through three-dimensional rendering, BIM software allows designers and engineers to see how elements in their projects work together. PDM software helps users track and control data, such as technical specifications, related to projects. Just as BIM is changing the work of architectural drafters as well as engineers and designers, PDM is changing the work of mechanical drafters. These software systems allow drafting and design work to be done at the same time as the work done by other professionals involved in the project.

There are several kinds of drafters, and the most common types of drafters are the following:

Aeronautical drafters prepare engineering drawings that show detailed plans and specifications used in manufacturing aircraft, missiles, and related parts.

Architectural drafters draw architectural and structural features of buildings for new construction projects. These workers may specialize in a type of building, such as residential or commercial. They may also specialize in materials, such as steel, wood, and reinforced concrete.

Civil drafters prepare topographical maps used in major construction or civil engineering projects, such as highways, bridges, and flood-control projects.

Electrical drafters prepare wiring diagrams that other workers use to install and repair electrical equipment and wiring in powerplants, electrical distribution systems, and buildings.

Electronics drafters produce wiring diagrams, assembly diagrams for circuit boards, and layout drawings used in manufacturing, installing, and repairing electronic devices and components.

Mechanical drafters prepare layouts that show details for a wide variety of machinery and mechanical devices. These layouts indicate dimensions, fastening methods, and other requirements needed for assembly.

Process piping or pipeline drafters prepare plans used in the layout, construction, and operation of oil and gas fields, refineries, chemical plants, and process piping systems.

Surveyors establish land, airspace, and water boundaries. They measure the Earth's surface to collect data that are used to draw maps, determine the shape and contour of parcels of land, and set property lines and boundaries. They also define airspace for airports and measure construction and mining sites. Surveyors work with civil engineers, landscape architects, and urban and regional planners to develop comprehensive design documents.

Surveyors typically do the following:

• Measure distances, directions, and angles between points on, above, and below the Earth's surface
• Select known reference points and then determine the exact location of important features in the survey area using special equipment
• Establish official land and water boundaries
• Research land records and other sources of information affecting properties
• Look for evidence of previous boundaries to determine where boundary lines are
• Travel to locations to measure distances and directions between points
• Record the results of surveying and verify the accuracy of data
• Prepare plots, maps, and reports
• Work with cartographers (mapmakers), architects, construction managers, and others
• Present findings to clients, government agencies, and others
• Write descriptions of land for deeds, leases, and other legal documents
• Provide expert testimony in court regarding their work or that of other surveyors

Surveyors guide construction and development projects and provide information needed for the buying and selling of property. In construction, surveyors determine the precise location of roads or buildings and proper depths for foundations and roads. Whenever property is bought or sold, it needs to be surveyed for legal purposes.

In their work, surveyors use the Global Positioning System (GPS), a system of satellites that locates reference points with a high degree of precision. Surveyors interpret and verify the GPS results. They gather the data that is fed into a Geographic Information System (GIS), which is then used to create detailed maps.

Surveyors take measurements in the field with a crew, a group that typically consists of a licensed surveyor and trained survey technicians. The person in charge of the crew (called the party chief) may be either a surveyor or a senior surveying technician. The party chief leads day-to-day work activities. For more information, see the profile on surveying and mapping technicians.

Some surveyors work in specialty fields to survey particular characteristics of the Earth. Examples include the following:

Geodetic surveyors use high-accuracy techniques, including satellite observations, to measure large areas of the Earth's surface.

Geophysical prospecting surveyors mark sites for subsurface exploration, usually to look for petroleum.

Marine or hydrographic surveyors survey harbors, rivers, and other bodies of water to determine shorelines, the topography of the bottom, water depth, and other features.

Construction equipment operators drive, maneuver, or control the heavy machinery used to construct roads, bridges, buildings, and other structures.

Construction equipment operators typically do the following:

• Check to make sure that equipment functions properly
• Clean, maintain, and make basic repairs to equipment
• Report malfunctions to supervisors
• Move levers, push pedals, or turn valves to activate power equipment
• Drive and maneuver equipment
• Coordinate machine actions with crew members in response to hand or audio signals
• Ensure that safety standards are met

Construction equipment operators use machinery to move construction materials, earth, and other heavy materials at construction sites and mines. They operate equipment that clears and grades land to prepare it for construction of roads, bridges, and buildings, as well as airport runways, power generation facilities, dams, levees, and other structures.

The following are types of construction equipment operators:

Operating engineers and other construction equipment operators work with one or several types of power construction equipment. They may operate excavation and loading machines equipped with scoops, shovels, or buckets that dig sand, gravel, earth, or similar materials. In addition to operating the familiar bulldozer, they operate trench excavators, road graders, and similar equipment. Sometimes, they may drive and control industrial trucks or tractors equipped with forklifts or booms for lifting materials. They also may operate and maintain air compressors, pumps, and other power equipment at construction sites.

Paving and surfacing equipment operators control the machines that spread and level asphalt or spread and smooth concrete for roadways or other structures. Paving and surfacing equipment operators may specialize further:

• Asphalt spreader operators turn valves to regulate the temperature of asphalt and the flow of asphalt onto the roadbed. They must ensure that the machine distributes the paving material evenly, and they also must ensure that there is a constant flow of asphalt into the hopper.
• Concrete paving machine operators control levers and turn handwheels to move attachments that spread, vibrate, and level wet concrete. They must watch the surface of the concrete carefully to identify low spots into which workers must add concrete.
• Tamping equipment operators use machines that compact earth and other fill materials for roadbeds or other construction sites. They also may operate machines with interchangeable hammers to cut or break up old pavement and drive guardrail posts into the ground.

Piledriver operators use large machines mounted on skids, barges, or cranes to hammer piles into the ground. Piles are long, heavy beams of wood or steel driven into the ground to support retaining walls, bridges, piers, or building foundations. Some piledriver operators work on offshore oil rigs.

Some workers operate cranes to move construction materials. For more information on these workers, see the profile on material moving machine operators.

Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers research, design, develop, build, and test mechanical devices, including tools, engines, and machines.

Mechanical engineers typically do the following:

• Analyze problems to see how a mechanical device might help solve the problem
• Design or redesign mechanical devices, creating blueprints so the device can be built
• Develop a prototype of the device and test the prototype
• Analyze the test results and change the design as needed
• Oversee the manufacturing process for the device

Mechanical engineers use many types of tools, engines, and machines. Examples include the following:

• Power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines
• Power-using machines, such as refrigeration and air-conditioning
• Industrial production equipment, including robots used in manufacturing
• Other machines inside buildings, such as elevators and escalators
• Machine tools and tools for other engineers
• Material-handling systems, such as conveyor systems and automated transfer stations

Like other engineers, mechanical engineers use computers extensively. Computers help mechanical engineers to do the following:

• Produce and analyze designs
• Simulate and test how a machine is likely to work
• Generate specifications for parts
• Monitor the quality of products
• Control manufacturing and production
