Technical drawings - Construction drawings - Simplified representation of demolition and rebuilding (ISO 7518:1983)

Specifies rules for symbols and markings in general arrangement drawings and assembly drawings. In general the applications shown concern plans. Views and sections can be shown similarly. Outlines, dimensions and information in texts and the representation of building construction and parts of buildings are listed in form of tables.

Zeichnungen für das Bauwesen - Vereinfachte Darstellung von Abriß und Wiederaufbau (ISO 7518:1983)

Diese Internationale Norm legt Regeln für Symbole, Markierungen und vereinfachte Darstellungen von Abriß und Wiederaufbau auf Anordungs-Zeichnungen und Zusammenbau-Zeichnungen fest. Sie betrifft im allgemeinen Pläne, Ansichten und Schnitte können in ähnlicher Weise dargestellt werden.

Dessins techniques - Dessins de construction - Représentation simplifiée de démolition et de reconstruction (ISO 7518:1983)

La présente Norme internationale prescrit des règles générales pour des symboles, inscriptions et représentations simplifiées de démolition et de reconstruction sur des dessins d'ensemble et d'assemblage. En général, les applications indiquées se réfèrent aux plans. Les vues et les coupes peuvent être traitées de la même manière.

Overview

EN ISO 7518:1999 (ISO 7518:1983) defines rules for the simplified representation of demolition and rebuilding on construction drawings. It standardizes symbols, markings and graphical conventions used on general arrangement drawings and assembly drawings-primarily plans, but also views and sections-to clearly show existing parts to be retained, parts to be removed, and new construction. The standard helps ensure consistent, unambiguous technical drawings for demolition and reconstruction projects.

Key topics

• Scope and purpose
  • Rules for symbols and markings that indicate demolition, rebuilding and retained elements on construction drawings.
  • Applies mainly to plans; similar conventions may be used for views and sections.
• Graphical conventions
  • Use of contrasting line types and weights to differentiate existing, removed and new parts (e.g., thin lines, thick lines, thin lines with crosses).
  • Hatching or shading to show areas of construction or removal, following ISO 4069 principles.
• Dimensions and textual information
  • Guidance on how to present existing and new dimensions and text; removed elements may be struck through, and new information clearly distinguished.
  • Recommendation to differentiate original versus new dimensions by numeral height or text style when helpful.
• Clarity and amplification
  • Emphasis on clear contrast between retained, removed and new elements; drawings should be supplemented by text when needed.
  • Recommended practice: provide both the original (existing) state annotated with planned changes and a separate drawing of the altered building.
• Structured representation
  • Outlines, dimensions and descriptive information for building parts are organized in tabular form as part of the standard’s guidance.

Applications

• Architects, structural and civil engineers, CAD technicians, draftspeople and contractors use EN ISO 7518 when preparing:
  • Demolition and reconstruction drawings for refurbishment, retrofit and partial rebuilding projects
  • Permit and planning submissions where communication of proposed removal and new work must be unambiguous
  • Shop and assembly drawings that show staged removal and replacement of components
• Useful for building owners, surveyors and authorities reviewing demolition scopes or change-of-use proposals.

Related standards

• ISO 128 - Technical drawings: general principles of presentation
• ISO 3098-1 - Technical drawings: lettering (commonly used characters)
• ISO 4069 - Representation of areas on sections and views (hatching/shading conventions)
• Adopted as CEN standard: EN ISO 7518

EN ISO 7518 supports clear, consistent demolition and rebuilding documentation-reducing misinterpretation, improving coordination on site, and streamlining regulatory review. Keywords: ISO 7518, EN ISO 7518, technical drawings, construction drawings, demolition representation, rebuilding symbols, hatching, CAD standards.

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bedies). 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 authorized has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take patt 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 7518 was developed by Technical Committee ISO/TC 10, Technical drawings, and was circulated to the member bodies in January 1982. lt has been approved by the member bodies of the following countries: Australia India Austria Italy Belgium Japan Brazil Netherlands Canada New Zealand China Poland Egypt, Arab Rep. of Romania South Africa, Rep. of Spain Sweden Thailand USA USSR The member bodies of on technical grounds : 0 following countries expressed disapproval of the docu Finland Norway United Kingdom International Organkation for Standardization, 19
