Curators oversee collections, such as artwork and historic items, and may conduct public service activities for an institution. Museum technicians and conservators prepare and restore objects and documents in museum collections and exhibits.

Curators, museum technicians, and conservators typically do the following:

• Acquire, store, and exhibit collections
• Select the theme and design of exhibits
• Develop or set up exhibit materials
• Design, organize, or conduct tours and workshops for the public
• Attend meetings and civic events to promote the institution
• Clean objects using cleansers, solvents, and soap solutions
• Direct and supervise curatorial, technical, and student staff
• Plan and conduct special research projects

Many objects and documents are important or historically significant. Curators, museum technicians, and conservators preserve and organize the display of these materials.

The following are occupational specialties:

Curators manage museums, zoos, aquariums, botanical gardens, nature centers, and historic sites. The museum director often is a curator. Curators direct the acquisition, storage, and exhibit of collections, including negotiating and authorizing the purchase, sale, exchange, or loan of collections. They also may authenticate, evaluate, and categorize the specimens in a collection.

Curators often oversee and help conduct the institution's research projects and related educational programs.

Today, an increasing part of a curator's duties involves fundraising and promotion, which may include writing and reviewing grant proposals, journal articles, and publicity materials. In addition, many curators attend meetings, conventions, and civic events.

Most curators specialize in a particular field, such as botany, art, or history. Those who work in large institutions may be highly specialized. A large natural history museum, for example, might employ separate curators for its collections of birds, fishes, insects, and mammals.

Some curators take care of their collections, some do research related to items in the collection, and others do administrative tasks. In small institutions with only one or a few curators, one curator may be responsible for a number of tasks, from taking care of collections to directing the affairs of the museum.

Museum technicians, commonly known as registrars, help curators by preparing and taking care of museum items. Registrars also may answer questions from the public and help curators and outside scholars use the collections.

Conservators manage, preserve, treat, and document works of art, artifacts, and specimens--work that may require substantial historical, scientific, and archaeological research. Conservators document their findings and treat items to minimize their deterioration or to restore them to their original state.

Conservators usually specialize in a particular material or group of objects, such as documents and books, paintings, decorative arts, textiles, metals, or architectural material. They use x rays, chemical testing, microscopes, special lights, and other laboratory equipment and techniques to examine objects, determine their condition, and decide on the best way to preserve them.

In addition to their conservation work, conservators participate in outreach programs, research topics in their specialty, and write articles for scholarly journals. They may be employed by a museum or other institution that has objects needing conservation, or they may be self-employed and have several clients.

Automotive body and glass repairers restore, refinish, and replace vehicle bodies and frames, windshields, and window glass.

Automotive body and glass repairers typically do the following:

• Review damage reports, prepare cost estimates, and plan work
• Remove damaged body parts, including bumpers, fenders, hoods, grilles, and trim
• Realign car frames and chassis to repair structural damage
• Hammer out or patch dents, dimples, and other minor body damage
• Fit, attach, and weld replacement parts into place
• Install and weatherproof windows and windshields
• Grind, sand, buff, and prime refurbished and repaired surfaces
• Apply new finish to restored body parts

Automotive body and glass repairers can repair most damage from everyday vehicle collisions and make vehicles look and drive like new. Damage may be minor, such as replacing a cracked windshield, or major, such as replacing an entire door panel.

Repair technicians use many tools for their work. To remove damaged parts, such as bumpers and door panels, they use pneumatic tools, metal-cutting guns, and plasma cutters. For major structural repairs, such as aligning the body, they often use heavy-duty hydraulic jacks and hammers. For some work, they use common handtools, such as metal files, pliers, wrenches, hammers, and screwdrivers.

In some cases, repair technicians do an entire job by themselves. In other cases, especially in large shops, they use an assembly line approach in which they work as a team with each repair technician specializing.

Although repair technicians sometimes prime and paint repaired parts, automotive painters generally perform these tasks. For more information, see the profile on painting and coating workers.

The following are occupational specialties: 

Automotive body and related repairers, or collision repair technicians, straighten metal panels, remove dents, and replace parts that cannot be fixed. Although they repair all types of vehicles, most work primarily on cars, sport utility vehicles, and small trucks. 

Automotive glass installers and repairers remove and replace broken, cracked, or pitted windshields and window glass. They also weatherproof newly installed windows and windshields with chemical treatments.

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:

• Consult with industry experts to discuss estimates and resolve issues
• Identify and quantify cost factors, such as production time and raw material, equipment, and labor expenses
• Travel to job sites to gather information on materials needed, labor requirements, and other factors 
• Read blueprints and technical documents to prepare estimates
• Collaborate with engineers, architects, owners, and contractors on estimates
• Use sophisticated computer software to calculate estimates 
• Evaluate a product's cost effectiveness or profitability
• Recommend ways to make a product more cost effective or profitable
• Prepare estimates for clients and other business managers
• Develop project plans for the duration of the project

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.

Archivists appraise, edit, and maintain permanent records and historically valuable documents. Many perform research on archival material.

Archivists typically do the following:

• Create and maintain accessible computer archives and databases
• Organize and classify archival records to make it easy to find materials
• Authenticate and appraise historical documents and archival materials
• Provide reference services and help for users
• Direct workers who help arrange, exhibit, and maintain collections
• Safeguard records by copying to film, videotape, disk, or computer formats
• Preserve and maintain documents and objects
• Set and administer policy guidelines concerning public access to materials
• Locate new materials and direct their acquisition and display

Archivists preserve many documents and records for their importance, potential value, or historical significance. Most archivists coordinate educational and public outreach programs, such as tours, workshops, lectures, and classes. Some work with the boards of institutions to administer plans and policies. In addition, archivists may research topics or items relevant to their collections.

Some archivists specialize in an area of history, such as colonial history, so they can more accurately determine which records in that area should be kept and should become part of the archives. Archivists also may work with specialized forms of records, such as manuscripts, electronic records, websites, photographs, maps, motion pictures, or sound recordings.

Archivists usually use computers to generate and maintain archival records. Professional standards for handling electronic archival records are still evolving. However, computer capabilities will continue to expand and more records will be stored and exhibited electronically, providing both increased access and better protection for archived documents.

Archives technicians help archivists organize, maintain, and provide access to historical documentary materials.

Heavy vehicle and mobile equipment service technicians inspect, maintain, and repair vehicles and machinery used in construction, farming, rail transportation, and other industries.

Heavy vehicle and mobile equipment service technicians typically do the following:

• Read and understand operating manuals, blueprints, and drawings
• Perform scheduled maintenance, such as cleaning and lubricating parts
• Diagnose and identify malfunctions, using computerized tools and equipment
• Inspect, repair, and replace defective or worn parts, such as bearings, pistons, and gears
• Overhaul and test major components, such as engines, hydraulics, and electrical systems
• Disassemble and reassemble heavy equipment and components
• Travel to worksites to repair large equipment, such as cranes

Heavy vehicles and mobile equipment are critical to many industrial activities, including construction and railroad transportation. Various types of equipment, such as farm machinery, cranes, and bulldozers, are used to move materials, till land, lift beams, and dig earth to pave the way for development and construction.

Heavy vehicle and mobile equipment service technicians repair and maintain engines, hydraulic systems, transmissions, and electrical systems of agricultural, industrial, construction, and rail equipment. They ensure the performance and safety of fuel lines, brakes, transmissions, and other systems.

With many types of equipment and mechanical and electrical systems, service technicians use diagnostic computers to identify problems and make adjustments or repairs. Although the use of computerized testing equipment, such as tachometers and dynamometers, is common, technicians also use many different power and machine tools, including pneumatic wrenches, lathes, and welding equipment.

Service technicians also use many different handtools, such as screwdrivers, pliers, and wrenches, to work on small parts and in hard-to-reach areas. They generally purchase these tools over the course of their careers, often investing thousands of dollars in their collections.

After locating malfunctions, service technicians repair, replace, and recalibrate components such as hydraulic pumps or spark plugs. This may involve disassembling and reassembling major equipment or making adjustments through an onboard computer program.

The following are types of heavy vehicle and mobile equipment service technicians:

Farm equipment mechanics service and repair farm equipment, such as tractors and harvesters. They also work on smaller consumer-grade lawn and garden tractors. Most mechanics work for dealer repair shops, where farmers increasingly send their equipment for maintenance.   

Mobile heavy equipment mechanics repair and maintain construction and surface mining equipment, such as bulldozers, cranes, graders, and excavators. Many work for equipment wholesale and distribution shops and large construction and mining companies. Those working for the federal government may work on tanks and other military equipment.

Rail car repairers specialize in servicing railroad locomotives, subway cars, and other rolling stock. They usually work for railroad, public and private transit companies, and rail car manufacturers.
