Sales managers direct organizations' sales teams. They set sales goals, analyze data, and develop training programs for the organization's sales representatives.
Sales managers typically do the following:
Sales managers' responsibilities vary with the size of the organization they work for. However, most sales managers direct the distribution of goods and services by assigning sales territories, setting sales goals, and establishing training programs for the organization's sales representatives.
In some cases, they recruit, hire, and train new members of the sales staff. For more information about sales workers, see the profiles on retail sales workers and wholesale and manufacturing sales representatives.
Sales managers advise sales representatives on ways to improve their sales performance. In large multiproduct organizations, they oversee regional and local sales managers and their staffs.
Sales managers also stay in contact with dealers and distributors. They analyze sales statistics that their staff gathers, both to determine the sales potential and inventory requirements of products and stores and to monitor customers' preferences.
Sales managers work closely with managers from other departments. For example, the marketing department identifies new customers that the sales department can target. The relationship between these two departments is critical to helping an organization expand its client base. Because sales managers monitor customers' preferences and stores' and organizations' inventory needs, they work closely with research and design departments and warehousing departments.
Cost estimators collect and analyze data to estimate the time, money, resources, and labor required for product manufacturing, construction projects, or services. Some specialize in a particular industry or product type.
Cost estimators typically do the following:
Accurately predicting the cost, size, and duration of future construction and manufacturing projects is vital to the survival of any business. Cost estimators' calculations give managers or investors this information.
When making calculations, estimators analyze many inputs to determine how much time, money, and labor a project needs, or how profitable it will be. These estimates have to take many factors into account, including allowances for wasted material, bad weather, shipping delays, and other factors that can increase costs and lower profitability.
Cost estimators use sophisticated computer software, including database, simulation, and complex mathematical programs. Cost estimators often use a computer database with information on the costs of other similar projects.
General contractors usually hire cost estimators for specific parts of a large construction project, such as estimating the electrical work or the excavation phase. In such cases, the estimator calculates the cost of the construction phase for which the contractor is responsible, rather than calculating the cost of the entire project. The general contractor usually also has a cost estimator who calculates the total project cost by analyzing the bids that the subcontractors' cost estimators prepared.
Some estimators are hired by manufacturers to analyze certain products or processes.
The following are the two primary types of cost estimators:
Construction cost estimators estimate construction work. More than half of all cost estimators work in the construction industry. They may, for example, estimate the total cost of building a bridge or a highway. They may identify direct costs, such as raw materials and labor requirements, and set a timeline for the project. Although many work directly for construction firms, some work for contractors, architects, and engineering firms.
Manufacturing cost estimators calculate the costs of developing, producing, or redesigning a company's goods and services. For example, a cost estimator working for a home appliance manufacturer may determine whether a new type of dishwasher will be profitable to manufacture.
Some manufacturing cost estimators work in software development. Many high-technology products require a considerable amount of computer programming, and the costs of software development are difficult to calculate.
Two other groups also sometimes do cost estimating in their jobs. Operations research, production control, cost, and price analysts who work for government agencies may do significant amounts of cost estimating in the course of their usual duties. Construction managers also may spend considerable time estimating costs. For more information, see the profiles on operations research analysts and construction managers.
Heating, air conditioning, and refrigeration mechanics and installers--often referred to as HVACR technicians--work on heating, ventilation, cooling, and refrigeration systems that control the air quality in many types of buildings.
Heating, air conditioning, and refrigeration mechanics and installers typically do the following:
Heating and air conditioning systems control the temperature, humidity, and overall air quality in homes, businesses, and other buildings. By providing a climate controlled environment, refrigeration systems make it possible to store and transport food, medicine, and other perishable items.
Although trained to do all three, HVACR technicians sometimes work strictly with heating, air conditioning, or refrigeration systems. They also may specialize in certain types of HVACR equipment, such as water-based heating systems, solar panels, or commercial refrigeration.
Depending on the task, HVACR technicians use many different tools. For example, they often use screwdrivers, wrenches, pipe cutters and other basic handtools when installing systems. To test or install complex system components, technicians may use more sophisticated tools, such as carbon monoxide testers, voltmeters, combustion analyzers, and acetylene torches.
When working on air conditioning and refrigeration systems, technicians must follow government regulations regarding the conservation, recovery, and recycling of refrigerants. This often entails proper handling and disposal of fluids.
Some HVACR technicians sell service contracts to their clients, providing regular maintenance of heating and cooling systems.
Other craft workers sometimes help install or repair cooling and heating systems. For example, on a large air conditioning installation job, especially one in which workers are covered by union contracts, ductwork might be done by sheet metal workers and duct installers, or electrical work by electricians. In addition, home appliance repairers usually service window air conditioners and household refrigerators. For more information on these occupations, see the profiles on sheet metal workers, electricians, or home appliance repairers.
Construction laborers and helpers do many basic tasks that require physical labor on construction sites.
Construction laborers and helpers typically do the following:
Construction laborers and helpers work on almost all construction sites, doing a wide range of tasks from the very easy to the extremely difficult and hazardous. Although many of the tasks they do require some training and experience, most jobs usually require little skill and can be learned quickly.
The following are occupational specialties:
Construction laborers do a variety of construction-related activities during all phases of construction. Although most laborers are generalists--such as those who install barricades, cones, and markers to control traffic patterns--many others specialize. For example, those who operate the machines and equipment that lay concrete or asphalt on roads are more likely to specialize in those areas.
Most construction laborers work in the following areas:
Construction laborers use a variety of tools and equipment. Some tools are simple, such as brooms and shovels; other equipment is more sophisticated, such as pavement breakers, jackhammers, earth tampers, and surveying equipment.
With special training, laborers may help transport and use explosives or run hydraulic boring machines to dig out tunnels. They may learn to use laser beam equipment to place pipes and use computers to control robotic pipe cutters. They may become certified to remove asbestos, lead, or chemicals.
Helpers assist construction craftworkers, such as electricians and carpenters, with a variety of basic tasks. They may carry tools and materials or help set up equipment. For example, many helpers work with cement masons to move and set forms. Many other helpers assist with taking apart equipment, cleaning up sites, and disposing of waste, as well as helping with any other needs of craftworkers.
Many construction trades have helpers who assist craftworkers. The following are examples of trades that have associated helpers:
Insulation workers install and replace the materials used to insulate buildings and their mechanical systems to help control and maintain temperature. Workers are often referred to as insulators.
Insulation workers typically do the following:
Properly insulated buildings save energy by keeping heat in during the winter and out in the summer. Insulated vats, vessels, boilers, steam pipes, and hot-water pipes also prevent the wasteful loss of heat or cold and prevent burns. Insulation also helps reduce noise that passes through walls and ceilings.
When renovating old buildings, insulators often must remove the old insulation. In the past, asbestos--now known to cause cancer--was used extensively to insulate walls, ceilings, pipes, and industrial equipment. Because of this danger, specially trained workers are required to remove asbestos before insulation workers can install the new insulating materials. For more information, see the profile on hazardous materials removal workers.
Insulation workers use common hand tools, such as knives and scissors. They also may use a variety of power tools including power saws to cut insulating materials, welders to secure clamps, and staple guns to fasten insulation to walls. Some insulators use compressors to spray insulation onto walls.
Workers sometimes wrap a cover of aluminum, sheet metal, or vapor barrier (plastic sheeting) over the insulation. Doing so protects the insulation by keeping moisture out.
The following are examples of insulation workers:
Floor, ceiling, and wall insulators install insulation in attics, floors, and behind walls in homes and other buildings. Most of these workers unroll, cut, fit, and staple batts of fiberglass insulation between wall studs and ceiling joists. Some workers, however, spray foam insulation with a compressor hose into the space being filled.
Mechanical insulators apply insulation to pipes or ductwork in businesses, factories, and many other types of buildings. When insulating a steam pipe, for example, the temperature, thickness, and diameter of the pipe are all factors that determine the type of insulation to be used.
