Solution

Answer 1:

The presentation drawings are the drawings that show the sketch of the building. These drawings are prepared to show to the client before the design process of the building plan so that the client can get an idea of the project and the building elevation. That helps to get the client's feedback before working on the drafting part. Presentation drawing present the project in front of the client,

Answer 2:

Isometric drawings are drawings that represent the isometric projection of the project. This projection is used to represent the three-dimensional design on the two-dimensional plane. These drawings are developed for presentation purposes. Isometric drawings are used to impress clients and present them with the finished product with two-dimensional elevation before starting the real drafting.

Answer 3:

Orthographic drawings are the graphical representation of a component on a two- dimensional plane from different view angles. When a product is designed to represent the visibility of the product from different angles it is important to draw the projection of the product from a different plane. Generally, the orthographic projection covers the three important views of the product including the front view, side view, and top view. All these projection views are developed to represent the different components of the project. The purpose of these drawings is to represent the different view angles of the project.

Answer 4:

Perspective drawing is a technique that is used to represent the depth and height of a drawing on paper. With the help of the depth and height illusion on the paper with the help of the perspective drawing the three-dimensional effect is represented for the building.

Answer 5:

a. sheet layout: Sheet layout is a rectangular area that represents the boundaries of the completed drawing it consists of all the required elements of the drawing including the title block and border. The sheet layout is divided as per the requirement of the drawings in the different sections. The purpose of selecting sheet layout is that some standards are used in the development of the drawing so that when the drawing is used by any person it can be easily understood and readable.

b. title block: The title block is the section on the sheet that contains all the information related to the drawing in the form of the table. There are different elements of the title block including title, ratio, projection, and creator details.

c. line types: In engineering drawing, there are different type of lines used that represents different perspective in the drawing making. These different types of lines are used to visually represent the different properties of the drawing. For example, there are solid lines that represent the boundaries, center lines that represent the center excess of the drawing, section lines that represent the section that divides the drawing into different parts, hidden line that represents the internal sections in the drawing, etc.

d. symbols: Drawings of buildings are the visual representation of the complete building project. it involves all the required information related to the project design and drafting. Complete information related to the drawing cannot be explained on the sheet of the drawing so symbols are used that represent different meanings. In the drafting, there are different types of symbols like door, window symbols, etc.

e. dimensions and dimension lines: Dimension is the representation of the height and width of the project on the sheet. The dimensions represent numerical values that are used to draw the drawing in a particular ratio. The dimension lines are the projections of the dimensions at a distance from the drawing area. These lines help to understand the limit between the two points represented in the form of the dimension.

f. Abbreviations: Abbreviations are the short description of a particular process and a part that is represented by the help of the symbol and the code. This code and symbols are only readable by the professional that makes the drawing clear.

Answer 6:

CAD software is a tool that is used for the design and drafting process of different building components. It eliminates the human efforts of drawing and eliminates the time consume and makes the designing and drafting process easy. It is easy to use and has different functionalities to represent the component visually. CAD software aims to resolve the major issues that are faced during the design in the drafting process and follow the global standards of drafting.

Answer 7:

Class 1 1A building is a residential building that stands alone and drawings on the basis of a single dwelling for the domestic nature. Duplex terrace houses townhouses are part of the class 1a buildings. Class 1B buildings are represented as buildings that are smaller than 300 square meters of area. These types of buildings include guest houses boarding houses or hostels. Such buildings are developed for living less than 12 people in the building.

Answer 8:

In the development of the drawings, there are different standards are defined that represent the different characteristics of the drawing that should be present while following the particular standard. AS 1170 series standards represent the permanent, groundwater, liquid pressure, rainwater ponding, and the earth process actions used in the structural design action of the building.

Answer 9:

There are different types of tools and techniques used in the building designing process and the modern construction process of the buildings is represented in the building information modeling. More than the tool and the software it is an approach to be used in the building designing process. Building information modeling is used to manage the complete building development process from start to end. It provides an effective data and information sharing facility between the different operators working on a particular project. The building information modeling process is completed in the different stages that are represented below. The step of building information modeling implementation is assessment. At this stage, the complete information related to the project is collected and evaluated for the designing processes. Further the project pre-design is created that involves the basic information related to the drawing and all the information’s are represented graphically. Taking further feedback from the different sources after the heat planning process the designing and construction process is completed. This is the third stage of the project. When the construction process is completed the 4th is the maintenance from expert expertise.

Answer 10:

a. Datum: It is the form that is used for representing all the elements of the building in the same drawing. It can be in any form but all the components of the drawing will be associated with this.

b. Easement: It is a right of the land and house owners to use contained areas of land together for their enjoyment. At that point, both the owners of the land agree to use the passage.

c. Set-back: It is an area around the building that may be the smallest area of the building but used for the open space. This can be in the front, side, or the bac area of the building. As per the building areas, the setback can be of different sizes.

Answer 11:

The foundation process is the base process of creating any building or a structure. The strength of the building is defined in the form of the strength of the foundation. Once the foundation of the structure is created the further construction process is started. Different type of foundations is available that are used as per the type of the building and the load capacity. After construction, the complete project to cover the external wall from the cement or any other material like clay and sand or tiles rendering process is used. In this process, the exterior walls are covered with cement for a better finish and to protect the interior environment from the exterior environment.

Answer 12:

Safety considerations:

Keep the surface clear and wet wipe the surface before starting drawing. Use the lease dust environment for the drawing to make it clear.

Environment considerations: For the drawing, the process makes sure to evaluate the maximum environmental efficiencies. Effectively manage the water supply and storage process in the drawing.
