1. BUILDING WORKING DRAWING WITH AUTOCAD CHAPTER ONE 1.2 INTRODUCTION What is building? Is a kind structure which is built with materials and including with foundation,plinth,walls,floors,roofs,chimneys,plumbing services,veranda,balcony and part of a building or any wall enclosing . Building drawing is one major industrial uses for Graphic Communication.

2. Purpose of building Primarily as shelter from weather,security,living space,privacy,to store belongings, and comfortably live and work . Types of building Residential building,education building , institutional building, Assembly building, Business building,Industrial building, Storage building.

3. CHAPTER TWO ARCHITECTURAL DRAWING

4. 1 . PRESENTATION DRAWING Communicate the form of the building in terms of shape, color and texture . Such drawing presented to: - a. Planning regulation offices for design approval . b. The client -To help him in understanding of the program. - To show to him the relationship of spaces and the general concept of the design.

5. - To illustrate to him the general appearance of the building. (The accommodation provided. The effect of the over all scheme on the environmental). c . The public - Produced for use in periodicals, magazines and other publications . d . Jury members in the evaluation of design competition award.

6. Three dimensional building

7. PRESENTATION DRAWINGS ARE ALSO CLASSIFIED IN TO TWO : I. Schematic presentation drawing and II. Design presentation drawing Schematic presentation drawing Concerned with the preliminary investigation process for a design. Provides, information about: the site, immediate surrounding (adjoining structures, roads, services etc…) : Development the entire site, like circulation pattern. : Rough idea of the functional

8. II. Design Presentation Drawing Those concerned with the presentation of design solutions. Provide information about: . Basic room arrangement . Exterior features . Immediate surrounding etc. … -Such drawings more need to convey information about appearance because they presented for less technically minded people. So the presentation should be easily understood and preferably three dimensional representation (like-perspective), etc. …

9. 2. WORKING DRAWING Drawing from which a design is constructed often called detail drawings because it describes and gives the dimensions of the details building parts being presented. Working drawings logically subdivide into location , assembly and component drawings . Location drawings , also called general arrangement drawings, include floor plans, sections and elevations: they show where the construction elements are located.

10. Assembly drawings show how the different parts are put together. For example, a wall detail will show the layers that make up the construction, how they are fixed to structural elements , how to finish the edges of openings , and how prefabricated components are to be fitted .

11. Component drawings enable self-contained elements e.g. windows and door sets, to be fabricated in a workshop, and delivered to site complete and ready for installation. Larger components may include roof trusses, cladding panels, cupboards and kitchens. Complete rooms, especially hotel bedrooms and bathrooms, may be made as prefabricated pods complete with internal decorations and fittings.

12. Purpose of working drawings Communicate technical information throughout the building team. To show how the design is to be materialized Means of obtaining official approval Helps in analysis of cost factor Establish the use of material Provides details of tender Provides details for demonstrating construction Assist in the measurement of progress of construction

13. Purpose……….. Convey information for people concerned in erecting the buildings Gives information to specification writer Indicate contract commitment Indicate degree of supervision Basic for ordering materials and components Generally, working drawings are presented to contractors while presentation drawings are to clients.

14. Requirement of working drawings Any working drawing should be:- Clearly representative Easily understood Free from unnecessary notes (repetitive details) Accurately drawn (proper also in line of work) Drawn with appropriate symbols and proper conventions Well dimensioned

15. To fulfill the above requirement any working drawing must contain certain information like General information on each drawing/schedule Name of project and location Project reference and drawing number Name of designer/consultant and address of contact including telephone number General description of contents of drawings Scales on drawings Date of drawing when completed Key plan Vicinity map

16. Key plan & vicinity map Key plans:- are small scale-drawing of the building and are usually shown on all drawings. Cross-hatching may be used to indicate that portion of the building involved in the project when less than the entire building is included. Vicinity map:- are small-scale map of the area used to locate the site of the project when direction to the site is considered necessary.

18. Symbols and nomenclature used in working drawings The drawing of an architectural working drawing requires a knowledge of the symbols and terms commonly used in the design and construction industry. In order to simplify the details on a drawing and to speed drawing time it is necessary to use architectural symbols.

19. RULES FOR DRAWING SYMBOLS Always use drawing instruments. Never draw the symbols freehand on a working drawing. Use an architectural drawing template to increase the speed and clarity of the Symbols. Be certain that the template figures are the same scale as your drawing's scale. The location of the symbol on the working drawing is closely approximated. If an exact location is required, dimensions must be added to the symbol on the drawing

20. RULES FOR DRAWING….. Symbols are not drawn to the exact size of the actual item. The general size of the architectural symbols will vary with the scale of the drawing. The symbol should be of convenient reading size, It should not be too small or large. Material symbols need not cover the full surface. Repetitious drawing symbols need not be completely drawn. Have references for architectural symbols available.

21. Paper size

22. RESIDENTIAL PLAN 1. Reading Floor plan :- is a horizontal sectional view of the building taken about between150cm -180 cm of the floor line. This is done of course to cut through the majority of openings in the walls and to provide a view of the equipment installed inside .

23. 2. Reading Elevation drawing An architectural elevation is a view of a building containing a height dimension. When elevations show the inside of a building, they are called interior elevations , when they show the out side, they are called simply elevations . Purpose   Exterior elevations Describe the exterior materials found on the structure. Provide a location for vertical dimensions. Show the relationship of two elements such as the height of the chimney in relationship to the roof of structure . Incorporate reference for building, window or door. Show any exterior design elements. Necessary to the satisfactory appearance on a building as the floor plan is to its satisfactory functioning.

24. Interior elevations Needed to explain the appearance of the components of the interior wall, the wall of the kitchens, bathrooms, and fireplaces walls and other walls with permanently installed on the walls such as bookshelves and openings.

25. SECTIONAL DRAWING It is a vertical view through the building. The direction of section lines or arrows is usually shown on the plan to help interpret the sectional view.

26. 3, Detail section Section views cat through a small segment of a building &drawing with enlarged scale window & door section stair section chiming section structural detail section

27. ROOF PLAN DRAWING A Roof may be defined as the upper most part of the building provided as a structural covering to protect the building from weather ( i.e. from rain, wind, sun, etc… ) structurally a roof is constructed in the same way as an upper floor, through the shape of its upper, surface may be different basically, a roof consists of structural elements which support roof coverings .

28. SITE PLAN A site plan is a specific type of plan, showing the whole context of a building or group of buildings. A site plan shows property boundaries and means of access to the site and near by structures if they are relevant to the design . Indicate new and existing buildings, structures, roads, parking, sidewalks, and site improvements.
