Drafting
and Architecture Careers
Architects
design the overall aesthetic and functional look of buildings and
other structures. The design of a building involves far more than
its appearance. Buildings also must be functional, safe, and economical,
and must suit the needs of the people who use them. Architects take
all these things into consideration when they design buildings and
other structures.
Architects
provide professional services to individuals and organizations planning
a construction project. They may be involved in all phases of development,
from the initial discussion with the client through the entire construction
process. Their duties require specific skillsdesigning, engineering,
managing, supervising, and communicating with clients and builders.
The
architect and client discuss the objectives, requirements, and budget
of a project. In some cases, architects provide various predesign
servicesconducting feasibility and environmental impact studies,
selecting a site, or specifying the requirements the design must
meet. For example, they may determine space requirements by researching
the number and type of potential users of a building. The architect
then prepares drawings and a report presenting ideas for the client
to review.
After
the initial proposals are discussed and accepted, architects develop
final construction plans. These plans show the buildings appearance
and details for its construction. Accompanying these are drawings
of the structural system; air-conditioning, heating, and ventilating
systems; electrical systems; plumbing; and possibly site and landscape
plans. They also specify the building materials and, in some cases,
the interior furnishings. In developing designs, architects follow
building codes, zoning laws, fire regulations, and other ordinances,
such as those requiring easy access by disabled persons. Throughout
the planning stage, they make necessary changes. Although they have
traditionally used pencil and paper to produce design and construction
drawings, architects are increasingly turning to computer-aided
design and drafting (CADD) technology for these important tasks.
Architects
may also assist the client in obtaining construction bids, selecting
a contractor, and negotiating the construction contract. As construction
proceeds, they may visit the building site to ensure the contractor
is following the design, adhering to the schedule, using the specified
materials, and meeting quality work standards. The job is not complete
until all construction is finished, required tests are made, and
construction costs are paid. Sometimes, architects also provide
postconstruction services, such as facilities management. They advise
on energy efficiency measures, evaluate how well the building design
adapts to the needs of occupants, and make necessary improvements.
Architects
design a wide variety of buildings, such as office and apartment
buildings, schools, churches, factories, hospitals, houses, and
airport terminals. They also design complexes such as urban centers,
college campuses, industrial parks, and entire communities. They
also may advise on the selection of building sites, prepare cost
analysis and land-use studies, and do long-range planning for land
development.
Architects
sometimes specialize in one phase of work. Some specialize in the
design of one type of buildingfor example, hospitals, schools,
or housing. Others focus on planning and predesign services or construction
management, and do minimal design work. They often work with engineers,
urban planners, interior designers, landscape architects, and other
professionals. In fact, architects spend a great deal of their time
in coordinating information from, and the work of, others engaged
in the same project. Consequently, architectsparticularly
at larger firmsare now using the Internet to update designs
and communicate changes for the sake of speed and cost savings.
Drafters
prepare technical drawings and plans used by production
and construction workers to build everything from manufactured products,
such as toys, toasters, industrial machinery, or spacecraft, to
structures, such as houses, office buildings, or oil and gas pipelines.
Their drawings provide visual guidelines, showing the technical
details of the products and structures and specifying dimensions,
materials to be used, and procedures and processes to be followed.
Drafters fill in technical details, using drawings, rough sketches,
specifications, codes, and calculations previously made by engineers,
surveyors, architects, or scientists. For example, they use their
knowledge of standardized building techniques to draw in the details
of a structure. Some drafters use their knowledge of engineering
and manufacturing theory and standards to draw the parts of a machine
in order to determine design elements, such as the number and kind
of fasteners needed to assemble it. They use technical Handbooks,
tables, calculators, and computers to do this.
Traditionally,
drafters sat at drawing boards and used pencils, pens, compasses,
protractors, triangles, and other drafting devices to prepare a
drawing manually. Most drafters now use computer-aided drafting
(CAD) systems to prepare drawings. Consequently, some drafters are
referred to as CAD operators. CAD systems employ computer workstations
to create a drawing on a video screen. The drawings are stored electronically
so that revisions or duplications can be made easily. These systems
also permit drafters to easily and quickly prepare variations of
a design. Although drafters use CAD extensively, it is only a tool.
Persons who produce technical drawings using CAD still function
as drafters, and need the knowledge of traditional draftersrelating
to drafting skills and standardsin addition to CAD skills.
Despite the near-universal use of CAD systems, manual drafting still
is used in certain applications.
Drafting work
has many specialties, and titles may denote a particular discipline
of design or drafting. Aeronautical drafters prepare engineering
drawings detailing plans and specifications used for the manufacture
of aircraft, missiles, and related parts.
Architectural
drafters
draw architectural and structural features of buildings and other
structures. They may specialize by the type of structure, such as
residential or commercial, or by the kind of material used, such
as reinforced concrete, masonry, steel, or timber.
Civil drafters
prepare drawings and topographical and relief maps used in major
construction or civil engineering projects, such as highways, bridges,
pipelines, flood control projects, and water and sewage systems.
Electrical
drafters prepare wiring and layout diagrams used by workers
who erect, install, and repair electrical equipment and wiring in
communication centers, powerplants, electrical distribution systems,
and buildings.
Electronic drafters
draw wiring diagrams, circuitboard assembly diagrams, schematics,
and layout drawings used in the manufacture, installation, and repair
of electronic devices and components.
Mechanical
drafters prepare detail and assembly drawings of a wide
variety of machinery and mechanical devices, indicating dimensions,
fastening methods, and other requirements.
Process piping
or pipeline drafters prepare drawings used for layout, construction,
and operation of oil and gas fields, refineries, chemical plants,
and process piping systems.
