Details for Civil Drafters


Description

Prepare drawings and topographical and relief maps used in civil engineering projects, such as highways, bridges, pipelines, flood control projects, and water and sewerage control systems.

Tasks

  • Produce drawings, using computer-assisted drafting systems (CAD) or drafting machines, or by hand, using compasses, dividers, protractors, triangles, and other drafting devices.
  • Draft plans and detailed drawings for structures, installations, and construction projects, such as highways, sewage disposal systems, and dikes, working from sketches or notes.
  • Review rough sketches, drawings, specifications, and other engineering data received from civil engineers to ensure that they conform to design concepts.
  • Draw maps, diagrams, and profiles, using cross-sections and surveys, to represent elevations, topographical contours, subsurface formations, and structures.
  • Supervise and train other technologists, technicians, and drafters.
  • Determine the order of work and method of presentation, such as orthographic or isometric drawing.
  • Finish and duplicate drawings and documentation packages according to required mediums and specifications for reproduction, using blueprinting, photography, or other duplicating methods.
  • Correlate, interpret, and modify data obtained from topographical surveys, well logs, and geophysical prospecting reports.
  • Supervise or conduct field surveys, inspections, or technical investigations to obtain data required to revise construction drawings.
  • Explain drawings to production or construction teams and provide adjustments as necessary.
  • Determine quality, cost, strength, and quantity of required materials, and enter figures on materials lists.
  • Locate and identify symbols on topographical surveys to denote geological and geophysical formations or oil field installations.
  • Calculate excavation tonnage and prepare graphs and fill-hauling diagrams for use in earth-moving operations.
  • Calculate weights, volumes, and stress factors and their implications for technical aspects of designs.
  • Plot characteristics of boreholes for oil and gas wells from photographic subsurface survey recordings and other data, representing depth, degree, and direction of inclination.

Interests

  • Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.
  • Investigative - Investigative occupations frequently involve working with ideas, and require an extensive amount of thinking. These occupations can involve searching for facts and figuring out problems mentally.
  • Artistic - Artistic occupations frequently involve working with forms, designs and patterns. They often require self-expression and the work can be done without following a clear set of rules.
  • Conventional - Conventional occupations frequently involve following set procedures and routines. These occupations can include working with data and details more than with ideas. Usually there is a clear line of authority to follow.

Education, training, experience

  • Education - Most occupations in this zone require training in vocational schools, related on-the-job experience, or an associate's degree.
  • Training - Employees in these occupations usually need one or two years of training involving both on-the-job experience and informal training with experienced workers. A recognized apprenticeship program may be associated with these occupations.
  • Experience - Previous work-related skill, knowledge, or experience is required for these occupations. For example, an electrician must have completed three or four years of apprenticeship or several years of vocational training, and often must have passed a licensing exam, in order to perform the job.

Knowledge

  • Physics - Knowledge and prediction of physical principles, laws, their interrelationships, and applications to understanding fluid, material, and atmospheric dynamics, and mechanical, electrical, atomic and sub- atomic structures and processes.
  • Clerical - Knowledge of administrative and clerical procedures and systems such as word processing, managing files and records, stenography and transcription, designing forms, and other office procedures and terminology.
  • English Language - Knowledge of the structure and content of the English language including the meaning and spelling of words, rules of composition, and grammar.
  • Geography - Knowledge of principles and methods for describing the features of land, sea, and air masses, including their physical characteristics, locations, interrelationships, and distribution of plant, animal, and human life.
  • Computers and Electronics - Knowledge of circuit boards, processors, chips, electronic equipment, and computer hardware and software, including applications and programming.
  • Building and Construction - Knowledge of materials, methods, and the tools involved in the construction or repair of houses, buildings, or other structures such as highways and roads.
  • Mathematics - Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications.
  • Engineering and Technology - Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services.
  • Design - Knowledge of design techniques, tools, and principles involved in production of precision technical plans, blueprints, drawings, and models.

Skills

  • Reading Comprehension - Understanding written sentences and paragraphs in work related documents.
  • Mathematics - Using mathematics to solve problems.
