Full title and description

GOST 21.502-2016 — System of design documents for construction. Execution rules of working documents for metal structures (Система проектной документации для строительства. Правила выполнения рабочей документации металлических конструкций). The standard defines the composition, structure and formal requirements for working documentation (mark KM) used for design, manufacture and erection of building metal structures.

Abstract

GOST 21.502-2016 establishes rules for preparing working drawings and accompanying lists/specifications for structural steel and other metal building elements. It standardizes drawing content and formats, specification forms, marking and notation (including welding symbols and load/impact information) to ensure unambiguous transfer of design information from designers to fabricators and contractors.

General information

• Status: Active / In force.
• Publication date: Approved late 2016; officially introduced 1 July 2017.
• Publisher: Adopted/approved through the Russian system of technical regulation (Federal Agency for Technical Regulation and Metrology / GOST system).
• ICS / categories: 01.100.30 (Generalities; terminology; documentation — technical and construction drawings).
• Edition / version: GOST 21.502-2016 (replaces GOST 21.502-2007).
• Number of pages: Approximately 30 pages (official published text: ~30 p., reprints/editions may show minor pagination differences).

Scope

The standard applies to the working documentation of building metal structures (drawings of the KM mark). It determines which documents, drawings, specifications and data are required to fully describe structural metal elements for fabrication, transport and installation — including general data, element and node drawings, lists of materials and metal rolling, loads and effects to be indicated, and conventions for graphical presentation and notation.

Key topics and requirements

• Composition of the KM working-document set: required drawings, specifications and summary lists.
• Rules for graphic presentation, views and general arrangement of metal-structure drawings (formats, title blocks, reference data).
• Specification content and forms for metal products, including required fields for profile, grade, dimensions and mass.
• Marking, dimensioning, tolerances and assembly/installation information required for fabrication and erection.
• Welding symbols, their placement and representation in drawings (appendix examples and references to welding symbol standards).
• Requirements for indicating loads, effects, corrosion protection and any special manufacturing or installation instructions.

Typical use and users

Used by structural engineers, architects (when coordinating metalwork), steel detailers and fabricators, design organizations producing working documentation (mark KM), construction contractors, quality inspectors and regulatory reviewers involved in structural metalwork projects.
