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.

Accountants and auditors prepare and examine financial records. They ensure that financial records are accurate and that taxes are paid properly and on time. Accountants and auditors assess financial operations and work to help ensure that organizations run efficiently. 

Accountants and auditors typically do the following:

• Examine financial statements to be sure that they are accurate and comply with laws and regulations
• Compute taxes owed, prepare tax returns, and ensure that taxes are paid properly and on time
• Inspect account books and accounting systems for efficiency and use of accepted accounting procedures
• Organize and maintain financial records
• Assess financial operations and make best-practices recommendations to management
• Suggest ways to reduce costs, enhance revenues, and improve profits

In addition to examining and preparing financial documentation, accountants and auditors must explain their findings. This includes face-to-face meetings with organization managers and individual clients, and preparing written reports.

Many accountants and auditors specialize, depending on the particular organization that they work for. Some organizations specialize in assurance services (improving the quality or context of information for decision makers) or risk management (determining the probability of a misstatement on financial documentation). Other organizations specialize in specific industries, such as healthcare.

Some workers with a background in accounting and auditing teach in colleges and universities. For more information, see the profile on postsecondary teachers.

The four main types of accountants and auditors are the following:

Public accountants do a broad range of accounting, auditing, tax, and consulting tasks. Their clients include corporations, governments, and individuals.

They work with financial documents that clients are required by law to disclose. These include tax forms and balance sheet statements that corporations must provide potential investors. For example, some public accountants concentrate on tax matters, advising corporations about the tax advantages of certain business decisions or preparing individual income tax returns.

External auditors review clients' financial statements and inform investors and authorities that the statements have been correctly prepared and reported.

Public accountants, many of whom are Certified Public Accountants (CPAs), generally have their own businesses or work for public accounting firms.

Some public accountants specialize in forensic accounting, investigating financial crimes, such as securities fraud and embezzlement, bankruptcies and contract disputes, and other complex and possibly criminal financial transactions. Forensic accountants combine their knowledge of accounting and finance with law and investigative techniques to determine if an activity is illegal. Many forensic accountants work closely with law enforcement personnel and lawyers during investigations and often appear as expert witnesses during trials.

Management accountants, also called cost, managerial, industrial, corporate, or private accountants, record and analyze the financial information of the organizations for which they work. The information that management accountants prepare is intended for internal use by business managers, not by the general public.

They often work on budgeting and performance evaluation. They may also help organizations plan the cost of doing business. Some may work with financial managers on asset management, which involves planning and selecting financial investments such as stocks, bonds, and real estate.

Government accountants maintain and examine the records of government agencies and audit private businesses and individuals whose activities are subject to government regulations or taxation. Accountants employed by federal, state, and local governments ensure that revenues are received and spent in accordance with laws and regulations.

Internal auditors check for mismanagement of an organization's funds. They identify ways to improve the processes for finding and eliminating waste and fraud. The practice of internal auditing is not regulated, but the Institute of Internal Auditors (IIA) provides generally accepted standards.

Information technology auditors are internal auditors who review controls for their organization's computer systems, to ensure that the financial data comes from a reliable source.

Laundry and dry-cleaning workers clean clothing, linens, drapes, and other articles, using washing, drying, and dry-cleaning machines. They also may clean leather, suede, furs, and rugs.

Laundry and dry-cleaning workers typically do the following:

• Receive items from customers and mark them with codes or names
• Inspect articles for stains and fabrics that require special care
• Sort articles to be cleaned by fabric type, color, and cleaning technique
• Load clothing into laundry and dry-cleaning machines
• Add detergent, bleach, and other chemicals to laundry and dry-cleaning machines
• Remove, sort, and hang clothing and other articles after they are removed from the machines
• Clean and maintain laundry and dry-cleaning machines

Laundry and dry-cleaning workers ensure proper cleaning of clothing, linens, and other articles. They adjust machine settings for a given fabric or article, as determined by the cleaning instructions on each item of clothing.

When necessary, workers treat spots and stains on articles before washing or dry-cleaning. They monitor machines during the cleaning process and ensure that items are not lost or placed with items of another customer.

Sometimes, laundry and dry-cleaning workers interact with customers. They take the receipts, find the customer's clothing, take payment, make change, and do the cash register work that retail sales people do.

Some dry-cleaners offer alteration services. Often, sewers and tailors do these tasks, but some laundry and dry-cleaning workers do them as well. For more information, see the profile on sewers and tailors.
