Drawings Construction drawings show, in graphic and quantitative form the:
extent, configuration, location, relationships, and dimensions
Drawings They generally contain:
site and building plans, elevations, sections, details, diagrams, and schedules
Drawings In addition to drawn information, they may include: Photographs Graphics Printed schedules Specifications (for small projects)
Drawings Definition:
A set of drawings is an organized presentation of the project.
Sample Projects
Example • For small projects, working drawings and details can be integrated in small number of sheets.
Example • For medium projects, a sufficient number of drawings need to be developed to cover all the required details.
SITE PLAN • The site plan should show the location of the building in relation to the site boundaries. • All landscape elements, streets and pedestrian walkways should be indicated and dimensioned. • A reference point should be identified to related the building to GPS.
PLANS • All plans should be drawn scale 1;100 showing centerlines, walls, openings, external dimensions, internal dimensions, materials, etc.
SECTIONS • Sections should illustrate vertical information including levels, materials, dimensions, corresponding centerlines and details cross-referencing.
ELEVATIONS • Elevations should illustrate exterior finishing materials, levels, dimensions, centerlines, and details crossreferencing.
WALL SECTIONS โ ข Wall sections illustrate exterior faรงade design detailing. They are extremely important illustration to ensure the final appreance of the design.

Title Block Format (1) Title Block Formats
Horizontal Text Format: Title block text is oriented parallel to the bottom of the sheet. The horizontal text format is the most commonly used, and is the preferred format.
Title Block Formats
Vertical Text Format: Title block text is oriented parallel to the right side of the sheet. Sheet title and sheet ID remain oriented parallel to the bottom of the sheet.

Drawings
Drawings should also include the basic information required to orient the user, such as: Key plans (showing location of partial plans in relation to the whole) North arrows Scales for drawings (graphic scales are normally included in case drawings are reduced or CAD generated)
Drawings The Cartooning Process Most firms lay out the drawings very early in the project. To establish roughly how many and what kinds of plans, sections, elevations, details, schedules, and other graphic elements will be prepared. Scale and size on sheet Order Interrelationships
COVER SHEET
WD CARTOON SET Assignment • • • • • • • • • •
Use A4 size paper to develop a rough sketch of your WD set. Determine the order of drawings and number ( __ of __ ) Sketch by hand the rough size of each drawing on each sheet Determine the scale needed (for example, plans should be at 1:100) Convert the real dimensions of the building drawings to the desired scale and show on your papers Make sure that all drawing fit on the size sheet plottable area Label each drawing, include the scale Add north arrow when appropriate Add descriptive text if known (such as window sill detail, east elevation, etc.) Add sheet names, numbers, and drawing title in the border
