Structure
This section describes the extent of the code, covering the preparation of working drawings and schedules related to building elements such as columns, foundations, openings, and fixtures. It details the standardized sheet sizes (A0, A1, A2 trimmed and untrimmed), scale selections ranging from general plans to fine details, and the use of schedules for repetitive components.
Defines the naming system for drawings to promote uniformity and clarity. It distinguishes between 'Ranges' which depict basic sizes, reference systems, and performance data for standard components, and 'Details' which provide complete manufacturing and application information. Emphasizes consistent terminology and use of standard symbols.
Discusses vertical views of buildings or elements, their arrangement on sheets, dimensioning conventions referencing established planes and benchmarks, and recommended scales from small to full size for accurate representation.
Explains the systematic approach to naming drawings by type (general arrangement, detail, assembly, range), component, drawing number, and revision status, fostering clarity and ease of reference.
Categorizes drawings based on purpose, such as ranges for standard sizes and details for manufacturing data, ensuring clear communication and standardized documentation.
Clarifies the role of working drawings in translating design into construction, emphasizing orthogonal projections for accuracy, detailing the extent of information included (design, dimensions, assembly), and distinguishing between drawing content and specifications.
Specifies that working drawings must clearly depict design details including locations, dimensions, and shapes, standardized sheet sizes, and that material quality and workmanship details are reserved for specifications.
Details the layout requirements including title block positioning at the bottom right corner with specified content, adherence to IS 962-1967 for title block formatting, standardized sheet sizes, and consistent drawing presentation.
Outlines dimensioning practices referencing an established baseline, rules for dimension line orientation and extension on plans and elevations, and the use of standardized sheet sizes to maintain clarity and uniformity.
Recommends minimal use of notes only when drawings alone cannot fully convey design intent, encourages improving drawings before adding notes, and advocates use of schedules for repetitive or detailed information like doors, finishes, and fixtures.
Explains the function of schedules to present repetitive or detailed data such as columns, doors, hardware, finishes, plumbing, and lighting fixtures in tabular form, improving clarity and reducing drawing complexity.
Mandates the use of graphical symbols as per IS 962:1967 for structural elements like beams, columns, foundations, and reinforcements, ensuring uniform representation and comprehension across drawings.
Describes the title block's purpose and layout requirements, placement in the bottom right corner of sheets, inclusion of essential metadata such as title, organization name, drawing number, scale, date, and compliance with IS 962:1967.
Provides detailed tables of trimmed and untrimmed sheet dimensions (A0, A1, A2), recommended scales for various types of drawings from general plans to detailed views, and reiterates title block placement and content guidelines.
Frequently Asked
The code specifies standardized sheet dimensions to be used for architectural working drawings as follows: trimmed sizes are 841 × 1189 mm (A0), 594 × 841 mm (A1), and 420 × 594 mm (A2), with untrimmed sheets slightly larger to allow for margins and handling. These sizes ensure uniformity and ease of use throughout the documentation.
Dimensions must be referenced to a clearly established reference plane, with their relationship to the benchmark explicitly shown. Dimension lines are to be read from the bottom or right side of the sheet. On plans, dimension lines extend in single horizontal lines, while on elevations and sections they extend vertically from bottom to top. Drawings should be grouped by type and maintain uniform sizes to facilitate site usability.
Working drawings encompass a range of detailed drawings essential for construction, including architectural plans, elevations, and sections; structural details such as foundations, columns, and reinforcements; service layouts for electrical, plumbing, and HVAC; site location plans; and assembly drawings with fully dimensioned parts. These collectively form the basis for construction execution.
Notes should be used sparingly and only when the drawing cannot independently communicate the design intent clearly. Efforts should first focus on enhancing the drawing itself before resorting to notes. Schedules are recommended for presenting repetitive or detailed information like columns, doors, finishes, and fixtures in a clear tabular format, which helps maintain the drawing's neatness and readability.
Graphical symbols must conform to the standards set by IS 962:1967, which provides uniform representations for architectural components such as doors, windows, walls, fixtures, and fittings. Utilizing these standardized symbols ensures clarity, consistency, and effective communication among all parties involved in the building process.
