Langley Construction & Development

Carpenters construct and repair building frameworks and structures--such as stairways, doorframes, partitions, and rafters--made from wood and other materials. They also may install kitchen cabinets, siding, and drywall.

Carpenters typically do the following:

• Follow blueprints and building plans to meet the needs of clients
• Install structures and fixtures, such as windows and molding
• Measure, cut, or shape wood, plastic, fiberglass, drywall, and other materials
• Construct building frameworks, including wall studs, floor joists, and doorframes
• Help put up, level, and install building framework with the aid of large pulleys and cranes
• Inspect and replace damaged framework or other structures and fixtures
• Instruct and direct laborers and other construction trade helpers

Carpenters are one of the most versatile construction occupations, with workers usually doing a variety of tasks. For example, some carpenters insulate office buildings; others install drywall or kitchen cabinets in homes. Those who help construct large buildings or bridges often make the wooden concrete forms for cement footings or pillars. Some carpenters build braces and scaffolding for buildings.

Carpenters use many different hand and power tools to cut and shape wood, plastic, fiberglass, or drywall. They commonly use handtools, including squares, levels, and chisels, as well as many power tools, such as sanders, circular saws, and nail guns. Carpenters put materials together with nails, screws, staples, and adhesives, and do a final check of their work to ensure accuracy. They use a tape measure on every project because proper measuring increases productivity, reduces waste, and ensures that the pieces being cut are the proper size.

The following are types of carpenters:

Residential carpenters typically specialize in new-home, townhome, and condominium building and remodeling. As part of a single job, they might build and set forms for footings, walls and slabs, and frame and finish exterior walls, roofs, and decks. They frame interior walls, build stairs, and install drywall, crown molding, doors, and kitchen cabinets. Highly-skilled carpenters may also tile floors and lay wood floors and carpet. Fully-trained construction carpenters are easily able to switch from new-home building to remodeling.

Commercial carpenters typically remodel and help build commercial office buildings, hospitals, hotels, schools, and shopping malls. Some specialize in working with light gauge and load-bearing steel framing for interior partitions, exterior framing, and curtain wall construction. Others specialize in working with concrete forming systems and finishing interior and exterior walls, partitions, and ceilings. Highly skilled carpenters can usually do many of the same tasks as residential carpenters.

Industrial carpenters typically work in civil and industrial settings where they put up scaffolding and build and set forms for pouring concrete. Some industrial carpenters build tunnel bracing or partitions in underground passageways and mines to control the circulation of air to worksites. Others build concrete forms for tunnels, bridges, dams, power plants, or sewer construction projects.

Farmers, ranchers, and other agricultural managers run establishments that produce crops, livestock, and dairy products.

Farmers, ranchers, and other agricultural managers typically do the following:

• Supervise all steps of the crop production and ranging process, including planting, fertilizing, harvesting, and herding
• Determine how to raise crops or livestock according to factors such as market conditions, federal program availability, and soil conditions
• Select and purchase supplies, such as seed, fertilizers, and farm machinery
• Operate and repair farm machinery so it cultivates, harvests, and hauls crops
• Adapt what they do as needed for weather and where the crop is in its growing cycle
• Maintain farm facilities, including its water pipes, hoses, fences, and animal shelters
• Serve as the sales agent for livestock and crops
• Keep financial, tax, production, and employee records

American farmers, ranchers, and other agricultural managers produce enough food and fiber to meet the needs of the United States and for export. However, farm output and income are strongly influenced by weather, disease, fluctuations in prices, and federal farm programs.

Farmers, ranchers, and other agricultural managers monitor the constantly changing prices for their product. They use different strategies to protect themselves from unpredictable changes in the markets.

Many farmers carefully plan the combination of crops that they grow, so if the price of one crop drops, they will have enough income from another crop to make up the loss. When farmers and ranchers plan ahead, they may be able to store their crops or keep their livestock to take advantage of higher prices later in the year.

Most farm output goes to food-processing companies. However, some farmers now choose to sell their goods directly to consumers through farmer's markets or use cooperatives to reduce their financial risk and gain a larger share of the final price of their goods. In community-supported agriculture, cooperatives sell shares of a harvest to consumers before the planting season to ensure a market for the farm's produce.

Farmers, ranchers, and other agricultural managers also negotiate with banks and other credit lenders to get financing because they must buy seed, livestock, and equipment before they have products to sell.

Farmers and ranchers own and operate mainly family-owned farms. They also may lease land from a landowner and operate it as a working farm.

The size of the farm or range determines which tasks farmers and ranchers handle. Those who operate small farms or ranges usually do all tasks. In addition to growing crops and raising animals, they keep records, service machinery, and maintain buildings.

Those who operate large farms, however, have employees--including agricultural workers-- who help with physical work. Some employees of large farms are in nonfarm occupations, working as truck drivers, sales representatives, bookkeepers, and IT specialists.

Both farmers and ranchers operate machinery and maintain their equipment and facilities. They track technological improvements in animal breeding and seeds, choosing new products that might improve output.

Agricultural managers take care of the day-to-day operation of one or more farms, ranches, nurseries, timber tracts, greenhouses, or other agricultural establishments for corporations, farmers, or owners who do not live and work on their farm or ranch.

Agricultural managers usually do not do production activities themselves. Instead, they hire and supervise farm and livestock workers to do most daily production tasks.

Managers may determine budgets. They may decide how to store and transport the crops. They oversee proper maintenance of equipment and property.

The following are some types of farmers, ranchers, and other agricultural managers:

Crop farmers and managers--those who grow grain, fruits and vegetables, and other crops--are responsible for all steps of plant growth. After a harvest, they make sure that the crops are properly packaged and stored.

Livestock, dairy, and poultry farmers, ranchers, and managers feed and care for animals. They keep livestock in barns, pens, and other well-maintained farm buildings. These workers also oversee breeding and marketing.

Horticultural specialty farmers and managers oversee the production of fruits, vegetables, flowers, and plants (including turf) used for landscaping. They also grow grapes, berries, and nuts used in making wine.

Aquaculture farmers and managers raise fish and shellfish in ponds, floating net pens, raceways, or recirculating systems. They stock, feed, protect, and maintain aquatic life used for food and for recreational fishing.

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.

Fire inspectors visit and inspect buildings and other structures, such as sports arenas and shopping malls, to search for fire hazards and to ensure that federal, state, and local fire codes are met. They also test and inspect fire protection and fire extinguishing equipment to ensure that it works. Fire investigators determine the origin and cause of fires by searching the surrounding scene and collecting evidence.

Fire inspectors typically do the following:

• Search for fire hazards
• Ensure that buildings comply with fire codes
• Test fire alarms, sprinklers, and other fire protection and extinguishing equipment
• Inspect equipment such as gasoline storage tanks and air compressors
• Review emergency evacuation plans
• Conduct follow-up visits when an infraction is found
• Confer with developers and planners to review plans for residential and commercial buildings
• Conduct fire and life safety education programs
• Keep detailed records that can be used in a court of law

Fire investigators typically do the following:

• Collect and analyze evidence
• Interview witnesses
• Determine the origin and cause of a fire
• Process and document evidence, such as photographs and diagrams
• Reconstruct the scene of a fire or arson
• Confer with other specialists, such as chemists, engineers, and attorneys, to analyze information
• Send evidence to laboratories to be tested for fingerprints or an accelerant
• Keep detailed records that can be used in a court of law
• Testify in civil and criminal legal proceedings

Unlike fire inspectors, many fire investigators have police powers and carry a weapon.

Forest fire inspectors and prevention specialists assess fire hazards in both public and residential areas. They look for issues that pose a wildfire risk and recommend ways to reduce the fire hazard. During patrols, they ensure that the public is following fire regulations and report fire conditions to central command.

Architects plan and design buildings and other structures.

Architects typically do the following:

• Seek new work by marketing and giving presentations
• Consult with clients to determine requirements for structures
• Estimate materials, equipment, costs, and construction time
• Prepare, design, and structure specifications
• Direct workers who prepare drawings and documents
• Prepare scaled drawings of the project
• Prepare contract documents for building contractors
• Manage construction contracts
• Visit worksites to ensure that construction adheres to architectural plans

People need places to live, work, play, learn, worship, meet, govern, shop, and eat. Architects are responsible for designing these places, whether they are private or public; indoors or outdoors; or rooms, buildings, or complexes.

Architects discuss with clients the objectives, requirements, and budget of a project. In some cases, architects provide various predesign services, such as feasibility and environmental impact studies, site selection, cost analyses and land-use studies, and design requirements. For example, architects may determine a building's space requirements by researching its number and types of potential users.

After discussing and agreeing on the initial proposal, architects develop final construction plans that show the building's appearance and details for its construction. Accompanying these plans are drawings of the structural system; air-conditioning, heating, and ventilating systems; electrical systems; communications systems; plumbing; and, possibly, site and landscape plans.

In developing designs, architects must follow building codes, zoning laws, fire regulations, and other ordinances, such as those requiring easy access by people who are disabled.

Computer-aided design and drafting (CADD) and building information modeling (BIM) technology have replaced traditional drafting paper and pencil as the most common methods for creating designs and construction drawings.

Architects also may help clients get construction bids, select contractors, and negotiate construction contracts.

As construction proceeds, architects may visit building sites to ensure that contractors follow the design, keep to the schedule, use the specified materials, and meet work-quality standards. The job is not complete until all construction is finished, required tests are conducted, and construction costs are paid.

Architects often work with workers in related professions. For more information on these occupations, see the profiles on civil engineers, urban and regional planners, interior designers, and landscape architects.
