TS 7749

TS 7749 is a terminology standard for the concepts used in setting out, measurement and surveying in building construction, together with their English, French and German equivalents. It helps different project participants use the same terms with the same meaning, and its explanatory and guidance notes support a consistent understanding of how those terms are applied in practice.

Why the terminology matters in building layout and survey work

In building construction, setting out is the process of transferring the design geometry to the site: axes, levels, corner points and other position references are marked where the work will be built. Measurement and surveying are then used to establish existing conditions, check positions and confirm that construction follows the design. By defining the vocabulary used in these activities, this standard reduces ambiguity in communication between design, site and control functions.

How the scope is organised

• Terms are defined together with multilingual equivalents.
• English, French and German equivalents are included.
• Explanatory and guidance notes clarify the practical use of the terms.
• The scope focuses on a common technical language for building setting out and surveying activities.

In general technical practice, terminology standards like this support coordination between survey teams, site management, design offices and inspection work. Distinguishing closely related concepts such as setting out, surveying and measurement is important because each addresses a different stage of controlling position, geometry and conformity on site. TS 7749 functions as a structured vocabulary reference for this field and is based on ISO 7078:1985 equivalence.
