Introduction to Code of Practice for Architectural and Building Drawings (IS: 962-1989, SP-46:2003)
In the field of civil engineering and drafting, standardization plays a crucial role in ensuring clarity, accuracy, and uniformity in drawings. The Bureau of Indian Standards (BIS) has developed specific codes to guide professionals in preparing architectural and building drawings. Among these, IS: 962-1989 and SP-46:2003 are important standards widely used in the Draughtsman Civil trade.
These codes provide detailed guidelines on drawing conventions, symbols, line types, and presentation methods. By following these standards, draughtsmen can create drawings that are easily understood by engineers, architects, and construction workers.
Overview of IS: 962-1989
IS: 962-1989 is the Indian Standard code that specifies the practice for architectural and building drawings. It provides guidelines for preparing drawings related to buildings, including plans, elevations, sections, and details.
The main objective of this code is to ensure that all drawings follow a uniform format and are easy to interpret.
- Standard symbols for building components
- Representation of materials such as brick, concrete, and steel
- Line types and their uses
- Dimensioning and lettering rules
- Drawing scales and layouts
This code helps in reducing confusion and errors during construction by providing clear and consistent drawing practices.
Overview of SP-46:2003
SP-46:2003 is a special publication issued by BIS that provides a comprehensive guide to architectural and building drawing practices. It complements IS: 962-1989 by offering detailed explanations, illustrations, and examples.
This publication is widely used as a reference for students and professionals to understand practical applications of drawing standards.
- Detailed examples of building drawings
- Explanation of symbols and conventions
- Guidelines for preparing plans, elevations, and sections
- Standard practices for presentation and layout
SP-46:2003 acts as a practical handbook that helps in implementing the standards effectively.

Key Elements Covered in the Codes
1. Line Types
Different types of lines are used in drawings to represent various elements. For example, continuous lines are used for visible edges, while dashed lines indicate hidden features.
2. Symbols
Standard symbols are used to represent doors, windows, sanitary fittings, electrical fixtures, and other building components. These symbols help in saving time and space in drawings.
3. Dimensioning
Proper dimensioning ensures that all measurements are clearly indicated. This is essential for accurate construction.
4. Scales
Drawings are prepared to scale to represent large structures on paper. Common scales include 1:50, 1:100, and 1:200.
5. Lettering and Notation
Standard lettering styles are used to maintain uniformity and readability in drawings.
Application in Practical Work
During training, students apply these codes while preparing various types of drawings such as:
- Building plans
- Elevation drawings
- Sectional views
- Detail drawings
