TS 7568

TS 7568 addresses the general rules for preparing engineering drawings used during the site assembly of prefabricated structures. In building and civil engineering documentation, it defines how working drawings should present the information needed to assemble components on site, helping create a common technical language for erection and installation work.

The technical role of prefabricated assembly drawings

In prefabricated construction, structural elements are typically manufactured off site and then transported for final assembly. Drawings in this context must do more than show geometry: they need to support erection sequence, relative positioning of elements, and the practical information installers require at the construction site. This makes the document distinct from general architectural or structural drawings, which may focus more broadly on design than on assembly coordination.

What this standard covers in broad terms

• General rules for working drawings intended for prefabricated buildings and other prefabricated civil engineering structures.
• Preparation principles for drawings to be used during field assembly on site.
• Issued as an equivalent national adoption of ISO 4172:1981.
• This record represents a withdrawn edition and is mainly of archival and historical technical value.

In general technical practice, prefabricated structure drawings are important coordination tools. When element references, assembly relationships, connection points, and layout logic are shown clearly, site errors are easier to avoid. TS 7568 is valuable because it formalizes that shared drawing discipline, helping different project teams and site crews work from the same technical language.
