Mechanical Door Repairers install, service, or repair automatic door mechanisms and hydraulic doors. Includes garage door mechanics.
Construction managers plan, coordinate, budget, and supervise construction projects from early development to completion.
Construction managers typically do the following:
Construction managers, often called general contractors or project managers, coordinate and supervise a wide variety of projects, including the building of all types of residential, commercial, and industrial structures, roads, bridges, powerplants, schools, and hospitals. They oversee specialized contractors and other personnel. Construction managers schedule and coordinate all design and construction processes to ensure a productive and safe work environment. They also make sure jobs are completed on time and on budget with the right amount of tools, equipment, and materials. Many managers also are responsible for obtaining necessary permits and licenses. They are often responsible for multiple projects at a time.
Construction managers work closely with other building specialists, such as architects, engineers, and a variety of trade workers, such as stonemasons, electricians, and carpenters. Projects may require specialists in everything from structural metalworking and painting, to landscaping, building roads, installing carpets, and excavating sites. Depending on the project, construction managers also may interact with lawyers and local government officials. For example, when working on city-owned property or municipal buildings, managers sometimes confer with city council members to ensure that all regulations are met.
For projects too large to be managed by one person, such as office buildings and industrial complexes, a construction manager would only be in charge of one part of the project. Each construction manager would oversee a specific construction phase and choose subcontractors to complete it. Construction managers may need to collaborate and coordinate with other construction managers who are responsible for different aspects of the project.
To maximize efficiency and productivity, construction managers often use specialized cost-estimating and planning software to effectively budget the time and money required to complete specific projects. Many managers also use software to determine the best way to get materials to the building site. For more information, see the profile on cost estimators.
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:
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.
For information about technicians and mechanics who work primarily on automobiles, see the profile on automotive service technicians and mechanics.
For information about technicians who work primarily on large trucks and buses, see the profile on diesel service technicians and mechanics.
For information about technicians and mechanics who primarily work on motorboats, motorcycles and small all-terrain vehicles, see the profile on small engine mechanics.
Parts Salespersons sell spare and replacement parts and equipment in repair shop or parts store.
Woodworkers build a variety of products, such as cabinets and furniture, using wood.
Woodworkers typically do the following:
Despite the abundance of plastics, metals, and other materials, wood products continue to be an important part of our daily lives. Woodworkers make wood products, using lumber and synthetic wood materials. Many of these products are mass produced, including most furniture, kitchen cabinets, and musical instruments. Other products are custom made with specialized tools in small shops.
Although the term “woodworker” may evoke the image of a craftsman who builds ornate furniture using hand tools, the modern woodworking trade is highly technical and relies on advanced equipment and highly skilled operators. Workers use automated machinery, such as computerized numerical control (CNC) machines, to do much of the work.
Even specialized artisans generally use a variety of power tools in their work. Much of the work is done in a high-production assembly line facility, but there is also some work that is customized and does not lend itself to being made in an assembly line. Woodworkers are employed in every part of the secondary wood products industry, from sawmill to finished product, and their activities vary.
Woodworkers set up, operate, and tend all types of woodworking machines, such as drill presses, lathes, shapers, routers, sanders, planers, and wood-nailing machines. Operators set up the equipment, cut and shape wooden parts, and verify dimensions, using a template, caliper, and rule. After wood parts are made, woodworkers add fasteners and adhesives and connect the pieces to form a complete unit. They then sand, stain, and, if necessary, coat the wood product with a sealer, such as a lacquer or varnish.
Many of these tasks are handled by different workers with specialized training.
The following are types of woodworkers:
Cabinetmakers and bench carpenters cut, shape, assemble, and make parts for wood products. They often design and create sets of cabinets that are customized for particular spaces. In some cases, their duties begin with designing a set of cabinets to specifications and end with installing them.
Furniture finishers shape, finish, and refinish damaged and worn furniture. They often work with antiques and must judge how to best preserve and repair them. They also do the staining and sealing at the end of the process of making wooden products.
Wood sawing machine setters, operators, and tenders specialize in operating specific pieces of woodworking machinery. They often operate computerized numerical control (CNC) machines.
Woodworking machine setters, operators, and tenders, except sawing, operate woodworking machines, such as drill presses, lathes, routers, sanders, and planers.
