Prepare detailed drawings of structural features of road, infrastructure or drawings and topographical relief maps used in civil engineering projects, such as highways, bridges, and public works. Use knowledge of building materials, engineering practices, and mathematics to complete drawings.
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.
Coordinate structural, electrical, and mechanical designs and determine a method of presentation to graphically represent building plans.
Analyze space and site requirements, and other technical documents and reports to determine their effect on architectural designs.
Draw maps, diagrams, and profiles, using cross-sections and surveys, to represent elevations, topographical contours, subsurface formations, and structures.
Lay out and plan interior room arrangements for commercial buildings, using computer-assisted drafting (CAD) equipment and software.
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.
Draw rough and detailed scale plans for foundations, buildings, and structures, based on preliminary concepts, sketches, engineering calculations, specification sheets, and other data.
Correlate, interpret, and modify data obtained from topographical surveys, well logs, and geophysical prospecting reports.
Check dimensions of materials to be used and assign numbers to lists of materials.
Determine procedures and instructions to be followed, according to design specifications and quantity of required materials.
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.

Obtain and assemble data to complete architectural designs, visiting job sites to compile measurements 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.
Create freehand drawings and lettering to accompany drawings.
Calculate excavation tonnage and prepare graphs and fill-hauling diagrams for use in earth-moving operations.
Prepare colored drawings of landscape and interior designs for presentation to client.
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.
Reproduce drawings on copy machines or trace copies of plans and drawings, using transparent paper or cloth, ink, pencil, and standard drafting instruments.
Calculate heat loss and gain of buildings and structures to determine required equipment specifications, following standard procedures.
Prepare cost estimates, contracts, bidding documents, and technical reports for specific projects under an architect's or engineer's supervision.
Represent architect or engineer on construction site, ensuring builder compliance with design specifications and advising on design corrections, under supervision.
Review rough sketches, drawings, specifications, and other engineering data to ensure that they conform to design concepts.
