KMK 3.03.02-98 PDF

Full title and description

KMK 3.03.02-98 — "Metal structures. Rules of manufacture and acceptance of works" (Металлоконструкции. Правила производства и приемки работ). The document sets technical and procedural requirements for fabrication, assembly, welding, inspection and acceptance of steel/metal structural elements used in buildings, industrial facilities and special-purpose installations.

Abstract

KMK 3.03.02-98 is a national construction technical norm that defines mandatory rules and acceptance criteria for the production and site installation of metal (steel) structures. It covers general fabrication rules, tolerances, welding and bolting practices, quality control, documentation and special provisions for certain types of structures (e.g., cylindrical tanks, masts and towerworks). The standard has been distributed in Russian and is included in national collections of KMK norms used in the region.

General information

• Status: National KMK construction norm; historically in-force for fabrication and acceptance of metal structures and listed in standards catalogs. Some commercial catalogs record it as replaced/updated by a later national regulation (listed as QR 03.02-23 in vendor metadata).
• Publication date: 1998 (edition indicated by the suffix "-98").
• Publisher: Issued/approved under the national state architecture/construction authority (Gosarchstroi / State Committee for Architecture and Construction — used in Uzbekistan and other CIS practice lists).
• ICS / categories: Construction — Structures of buildings: ICS 91.080 (metal/steel structures subcategories such as 91.080.10 / 91.080.13 for metal and steel structures).
• Edition / version: 1998 (original KMK 3.03.02-98 edition).
• Number of pages: Approx. 68 pages (electronic PDF editions offered by standards resellers list this page count).

Scope

KMK 3.03.02-98 applies to manufacture, shop assembly, transport, erection, welding and final acceptance of metal (steel) structural elements for buildings and certain industrial structures. It establishes general rules applicable to a broad range of steel structures and contains additional, specific provisions for several categories such as building frameworks, cylindrical vertical reservoirs, gas holders, and mast/tower constructions. The scope includes dimensional tolerances, requirements for weld quality and consumables, acceptance testing and required documentation for handover to commissioning.

Key topics and requirements

• General fabrication requirements and permissible dimensional tolerances for parts and assemblies.
• Rules for shop assembly, temporary tack-welding and final welding; requirements for welding materials and weld quality control.
• Inspection and non-conforming work procedures, including acceptance criteria for welded and bolted joints.
• Special provisions for specific structure types: cylindrical reservoirs, gas holders, masts/towers and heavy industrial components.
• Documentation and marking: records of inspections, certificates for materials and welders’ qualifications, and as-built documentation required for acceptance.
• Site installation, alignment and final acceptance tests including criteria for repairs and rework.

Typical use and users

Primary users are structural fabricators, erection contractors, welding supervisors and quality-control/inspection personnel involved in steelwork production and installation. Designers and project engineers use the standard to set production and acceptance requirements in contracts and shop/assembly drawings. Regulatory authorities and construction inspectors refer to the KMK when validating conformity of fabrication and erection works in jurisdictions where these norms are adopted or referenced. The document is commonly referenced in construction projects within Uzbekistan and in project documentation for nearby CIS countries.

Related standards

KMK 3.03.02-98 sits in a suite of KMK construction norms (e.g., KMK 3.03.01-98 for bearing and enclosing structures, KMK 3.04.02-97 on corrosion protection) and historically replaces or supplements older SNiP/SN-type rules (for example, it replaces provisions of СНиП III-18-75 in its domain). Modern national or regional updates and technical regulations may supersede portions of it; practitioners should check the current national rule set for the project jurisdiction.

FAQ

Q: What is this standard?

A: KMK 3.03.02-98 is a national construction technical norm titled "Metal structures. Rules of manufacture and acceptance of works" that sets mandatory production and acceptance rules for steel/metal structures (issued in 1998 under the KMK series of norms).

Q: What does it cover?

A: It covers shop and site procedures for fabrication, assembly, welding, inspection and final acceptance of metal structural elements, including tolerances, welding practice, special rules for tanks/masts and the required documentation for acceptance.

Q: Who typically uses it?

A: Steel fabricators, erection contractors, welding supervisors, QC/inspection teams, structural designers and local construction authorities in jurisdictions where KMK norms apply (notably Uzbekistan and other CIS countries that reference KMK documents).

Q: Is it current or superseded?

A: The 1998 KMK edition is the original normative document for its topic; however, commercial standards repositories and national practice notes sometimes list newer national regulations or codes that update or replace parts of KMK 3.03.02-98 (one vendor listing notes a replacement reference QR 03.02-23). Always confirm the active status with the local national authority or project regulator before relying on it for current compliance.

Q: Is it part of a series?

A: Yes — KMK 3.03.02-98 is part of the KMK family of construction norms (grouped by topic and building elements), and is commonly used alongside related KMK documents covering bearing/enclosing structures, protective measures, and material-specific production rules.

Q: What are the key keywords?

A: Metal/steel structures, fabrication, acceptance, welding, tolerances, inspection, construction norms, KMK 3.03.02-98.
