Chapter Nine: Construction Drawings (page 93)

Chapter One: Drawing Sheet Layout

Introduction: Key tool for communication among architects and designers
Types of drawings: quick sketches and detailed construction drawings
Purpose of drawings: development of ideas, solutions, and design details
Common errors: uncoordinated drawings, errors with numbering, and omissions of information.
Composition: importance of knowing who the drawing is for and what information they need.

Chapter Two: General Preparation for Drawing

Drawing board and stool: Arrange for comfortable work without fatigue or eye strain.
Lighting: Well-lit area, ideally from the front-left (or front-right for left-handed).
Cleaning instruments: Cleanliness is essential to prevent damage to the drawing sheet.
Planning and layout of sheet: Clear, rational, and easy-to-read layout, consistent with appearance of other drawings.
Drawing numbers in a chronological fashion: Follow a consistent numbering scheme.
Titleblock orientation: Be consistent with the orientation of your title block.
Font and style: Use a consistent font and style throughout all drawings.
Alignment: Ensure proper alignment of all drawings.

Chapter Three: Lines and Lettering

Lines: Used for communication of shape and size in technical drawings.
Lettering: Used to write titles, dimensions, and other details on engineering drawings.
Types of lines: Continuous lines, dashed lines, dashed-space lines, and other varieties.
Line thickness: Line weight for better readability.
Spacing: Sufficient space between lines for clear readability with minimum 0.7 mm.

Chapter Four: Dimensioning

Dimensions: Values to specify shape, size (length, breadth, height, diameter, radius, angle, and location)
Dimension lines: Thin continuous lines that indicate the extent and direction of a dimension.
Projection lines: Thin continuous lines that help locate the features for dimensions.
Leaders or pointer lines: Thin continuous lines that point to a feature and associated notes.
Arrowheads: Used for the termination of dimension lines (different varieties for different purposes).
Placement: Ideal placement of dimensions is near the middle of the dimension line.
Dimension systems: Unidirectional, aligned, parallel, and superimposed.

Chapter Five: Labelling and Annotation

Drawing labels: Necessary for each drawing to provide clarity: title, drawing number, scale, and paper size.
Markers: Reference markers for elevations, sections, and details (showing specific section reference or views).
Key/Legend: Reference guide to clarify elements in the drawings.
Line weights: Used to indicate different elements like boundaries, cutting planes, etc.

Chapter Six: Architecture Presentation Board

Purpose: To visually communicate design concepts, details and renderings, for both academic and professional purposes.
Content: Include floor plans, elevations, sections, and perspectives including 3D drawings or renders.
Requirements: Clear, well-organised layout, with good use of lines, weights and hatches, and text.
Planning: Plan the structure, content and presentation of the boards.
Inspiration: Use relevant precedents, graphic styles, and consistency.
Architecture representation: Communicate ideas and essential aspects of the scheme clearly.
Clarity: Prioritise quality over quantity, consider a simple layout and use of relevant visuals.
Layout options: Use of grids, proper placement of elements, maintain a clear hierarchy.

Chapter Seven: Plans

Introduction: Provide essential information for a planning phase or construction.
Types of plans: Floor plans (basic and more detailed), demonstrating important elements and components of a building
Basic Floor plan requirements: showing walls, openings, doors and windows, grids, relevant internal parts.
Construction Drawings: Providing more detailed information regarding the construction process.
Floor plan labelling: Provide labels for rooms, walls, and objects of the plan.
Important Information on plans: Showing north, scales, and entrance points

Chapter Eight: Elevations and Sections

Introduction: To explain the differences between Elevations and Sections.
Elevations: Vertical representation of surfaces (external – like facades or internal – like walls).
Sections: Vertical representation of a 2D cut within a 3D space.
Information required in Elevation Drawings: The important elements and components within an elevation must be shown clearly, with relevant details including dimensions, materials, and finishes.
Information required in Section Drawings: Showing the relationships between levels, ceilings, walls, and other components

Chapter Nine: Construction Drawings

Introduction: Detail drawings to further communicate the design and construction process
Purpose: To provide all the necessary information required for the construction.
Important Elements of Drawings: Detailed drawings of walls, doors, windows, fixtures, fittings, and other key parts.
Schedules: A schedule provides details, dimensions, locations, finishes, and other associated information for construction of doors or windows.

General Information for all Chapters

Title Blocks: Consistent title blocks throughout the drawings.
Image Use: Use high-impact images to improve visual understanding.
Visual Hierarchy: Create a visual hierarchy to emphasise crucial parts of the drawings.
