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• Authenticate and appraise historical documents and archival materials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.

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.

Appraisers and assessors of real estate estimate the value of real property--land and the buildings on that land-- before it is sold, mortgaged, taxed, insured, or developed.

Appraisers and assessors of real estate typically do the following:

• Verify legal descriptions of real estate properties in public records
• Inspect new and existing properties, noting unique characteristics
• Photograph the interior and exterior of properties
• Use “comparables,” or similar nearby properties, to help determine value
• Prepare written reports on the property value
• Prepare and maintain current data on each real estate property                             

Appraisers and assessors work in localities that they are familiar with so that they know any environmental or other concerns that may affect the property's value.

Appraisers typically value one property at a time, and they often specialize in a certain type of real estate. For example,

• Commercial appraisers specialize in property used commercially, such as office buildings, stores, and hotels.
• Residential appraisers focus on appraising property in which people live, such as duplexes and condominiums, and appraise only those that house one to four families.

When estimating a property's value, appraisers note unique characteristics of the property and surrounding area, such as a noisy highway nearby. They also consider the condition of a building's foundation and roof or any renovations that may have been done. In addition to photographing the outside of the building to document its condition, appraisers might also photograph a certain room or feature. After visiting the property, the appraiser estimates the value of the property by considering things such as comparable home sales, lease records, location, view, previous appraisals, and income potential. During the entire process, appraisers meticulously record their research, observations, and methods used in calculating the property's value.

Assessors mostly work for local governments and value properties for property tax assessments. Unlike appraisers, who generally focus on one property at a time, assessors often value an entire neighborhood of homes at once by using mass appraisal techniques and computer-assisted mass appraisal systems.

Assessors must be up-to-date on tax assessment procedures. Taxpayers sometimes challenge the assessment because they feel they are being charged too much for property tax. Assessors must be able to defend the accuracy of their property assessments, either to the owner directly or at a public hearing.

Assessors also keep a database of every property in their jurisdiction, identifying the property owner, assessment history, and size of the property, as well as property maps detailing the property distribution of the jurisdiction.

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.

Environmental engineers use the principles of engineering, soil science, biology, and chemistry to develop solutions to environmental problems. They are involved in efforts to improve recycling, waste disposal, public health, and control of water and air pollution. They also address global issues, such as safe drinking water, climate change, and sustainability.

Environmental engineers typically do the following:

• Prepare, review, and update environmental investigation reports
• Design projects leading to environmental protection, such as water reclamation facilities, air pollution control systems, and operations that convert waste to energy
• Obtain, update, and maintain plans, permits, and standard operating procedures
• Provide technical support for environmental remediation projects and legal actions
• Analyze scientific data and do quality-control checks
• Monitor progress of environmental improvement programs
• Inspect industrial and municipal facilities and programs to ensure compliance with environmental regulations
• Advise corporations and government agencies about procedures for cleaning up contaminated sites

Environmental engineers conduct hazardous-waste management studies in which they evaluate the significance of the hazard and advise on treating and containing it. They also design municipal water supply and industrial wastewater treatment systems and research the environmental impact of proposed construction projects. Environmental engineers in government develop regulations to prevent mishaps.

Some environmental engineers study ways to minimize the effects of acid rain, global warming, automobile emissions, and ozone depletion. They also collaborate with environmental scientists, planners, hazardous waste technicians, engineers, and other specialists, such as experts in law and business, to address environmental problems and sustainability.
