Overview
ISO 3881:1977 - Building construction - Modular co-ordination - Stairs and stair openings - Co-ordinating dimensions - gives general principles for establishing coordinated dimensions for stairs and stair openings in building construction. Applicable to buildings of all types, the standard is part of the ISO series on modular co-ordination, helping designers and manufacturers align stair geometry with a building’s modular grid and finished floor levels.
Key topics and requirements
- Scope and definitions: Uses vocabulary and definitions from related ISO documents (ISO 1791 and ISO 3880).
- Co-ordinating planes: Stair openings are bounded by co-ordinating planes; enclosing walls and floor heads must not trespass these boundary planes.
- Horizontal coordinating dimensions:
- Preferred dimensions are multiples of 3 M (n × 3 M).
- Secondary preference is multiples of 1 M (n × 1 M).
- Vertical coordinating dimensions:
- Vertical distances between co-ordinating planes shall be multiples of 1 M.
- Co‑ordinating planes for floor locations are related to finished floor levels (as illustrated in the standard).
- Illustrative examples: The standard includes application diagrams showing co-ordinating planes, enclosing walls and typical layout examples to guide practical implementation.
Practical applications
ISO 3881 is intended to make stair and stair-opening dimensions compatible with modular building systems, which supports:
- Consistent stair geometry across multi-storey buildings
- Easier integration of prefabricated stair elements with modular floors and structural grids
- Reduced on-site adjustment and clashes between stair openings and enclosing walls or floor heads
- Clear reference points for finished floor level integration
Typical users:
- Architects and building designers specifying stair and opening layouts
- Structural and façade engineers coordinating openings with structural grids
- Manufacturers of prefabricated stair components and modular building systems
- Contractors, site planners, and BIM modelers ensuring dimensional coordination during design and construction
Related standards
ISO 3881 forms part of a modular co‑ordination series; important companion documents include:
- ISO 1006 - Modular co-ordination - Basic module
- ISO 1040 - Multimodules for horizontal co-ordinating dimensions
- ISO 1789 - Storey heights and room heights for residential buildings
- ISO/R 1790 and ISO 1791 - Reference lines and vocabulary for modular co‑ordination
- ISO 2848 - Principles and rules of modular co‑ordination
Applying ISO 3881 helps ensure that stairs and stair openings fit neatly into a building’s modular design framework, improving constructability and interoperability of components.

FOREWORD
ISO (the International Organitation for Standardization) is a worldwide federation
of national Standards institutes (ISO member bodies). The work of developing
International Standards is carried out through ISO technical committees. Every
member body interested in a subject for which a technical committee has been set
up has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the ISO Council.
International Standard ISO 3881 was developed by Technical (Zornmittee
and was circulated to the member bedies in
ISO/TC 59, Building construction,
October 1975.
