alustekningur

Alustekningur is a term used in Icelandic technical practice to denote a preparatory drawing or mark-up on a base surface, used in fields such as architecture, construction, and surveying. It involves laying out the base geometry, reference lines, and alignment points that will guide subsequent work on a project.

Practice typically includes selecting an appropriate scale, transferring measurements from plans or field surveys, and marking lines with chalk, pencil, ink, or other marking tools on the substrate. The resulting alustekningur serves as a guide for operations such as excavation, framing, masonry, or installation, helping ensure correct positioning and orientation.

Often the markings are temporary, intended to be erased or incorporated into the final documentation after the relevant work is completed. In some contexts, the marks may be preserved in the as-built drawings to record the basis of the work.

Origin and usage: The word combines alusta meaning base or substrate and tekningur meaning drawing or notation, reflecting its function as a base layer for subsequent design and construction steps.
