PNST 505-2022 PDF

Full title and description

PNST 505-2022 — "Automobile roads of general use. Rules for description of components of information modelling". This preliminary national standard (PNST) defines the structure and requirements for describing components used in digital information models (BIM/CIM) of public highways and associated road infrastructure, including geometric, attribute and metadata naming rules, intended to support design, construction, operation and lifecycle management of roads.

Abstract

PNST 505-2022 establishes rules for the creation and description of reusable components (libraries, parametric objects and information containers) for information models of public highways. It specifies required geometric and attribute parameters, metadata conventions, recommended open exchange formats and principles for use within a common data environment to enable interoperability across lifecycle stages (planning, design, construction, operation, repair and decommissioning). The document aligns national practice with international BIM data principles (ISO 19650 series) and with Russian national guidance for information modelling in construction.

• Publication date: Approved 9 March 2022 (Order No. 21‑пнст); effective date 1 April 2022.
• Publisher: Federal Agency on Technical Regulating and Metrology (Rosstandart); developed by the Federal Autonomous Institution "Russian Road Scientific Research Institute" (ROSDORNII).
• ICS / categories: OKC/ICS 93.080.99 (road infrastructure / information modelling for roads).

• Number of pages: 36 pages (electronic PDF distribution noted in commercial catalogues).

Scope

The standard applies to the processes for creating and describing components of information models for public automobile roads and associated structures. It covers rules for formation and documentation of component geometry, attributes and metadata; principles for building knowledge libraries and object-type libraries; recommended exchange formats and requirements needed to support decision-making at all lifecycle stages of road assets. It is intended for use in preparation of engineering surveys, design and working documentation for construction, overhaul and reconstruction of highways.

Key topics and requirements

• Definitions and classification of components (components, parametric objects, information containers) used in road information models.
• Mandatory geometric, attribute and functional parameters for components and rules for attributive data.
• Metadata naming conventions and requirements for component identification to enable search, reuse and lifecycle traceability.
• Guidance on libraries (knowledge libraries, object-type libraries, component libraries) to support consistent reuse and decision-making.
• Recommendations for open exchange formats (IFC, LandXML and similar) and for interoperability consistent with ISO 19650 principles.
• Requirements for common data environment (CDE) usage, collision detection, and information delivery planning across lifecycle stages.

Typical use and users

Primary users include national, regional and municipal road authorities, highway designers and engineering consultancies, construction contractors, asset owners and operators, developers of engineering and GIS/BIM software, database and component library vendors, and manufacturers of road materials and equipment who supply data for digital models. Typical uses are development of component libraries, preparation of design and working documentation, interoperability and data exchange during procurement and construction, and lifecycle asset management.

Related standards

PNST 505-2022 is part of a set of PNST documents on information modelling for roads (for example PNST 506-2022 on formation and application of information models). It references and aligns with Russian construction information modelling guidance SP 328.1325800.2020 and SP 333.1325800.2020, and international standards such as the ISO 19650 series and ISO/IEC agreements on information exchange (e.g. ISO 12006 family).

FAQ

Q: What is this standard?

A: PNST 505-2022 is a preliminary national standard of the Russian Federation that sets rules for describing components used in digital information models for public highways and associated road structures.

Q: What does it cover?

A: It covers definitions, required geometric and attribute parameters, metadata naming, library structures, recommended exchange formats and principles for using component data across planning, design, construction and operation stages of road asset lifecycles.

Q: Who typically uses it?

A: Road agencies, designers, contractors, asset managers, software and library developers, and suppliers who need to prepare, exchange or reuse component data in road information models.

Q: Is it current or superseded?

A: PNST 505-2022 was approved in March 2022 and came into effect on 1 April 2022 as a preliminary national standard; its preliminary validity period is through 1 April 2025 unless it is confirmed, revised or superseded earlier. Users should check the national registry or Rosstandart notices for updates or final adoption.

Q: Is it part of a series?

A: Yes — it is issued together with companion PNST documents addressing information modelling for roads (for example PNST 506-2022) and is intended to work alongside Russian information modelling standards and international frameworks (SP 328/333, ISO 19650).
