Unit 6 lesson 5: Scale Drawings in BSE

Why are scale drawings used in Building Services Engineering (BSE) and construction?

• To create artistic representations of buildings

• To provide a means of passing on and sharing complex information

• To reduce the cost of drawing materials

• To make the construction process faster

What is generally shown in scale drawings used in BSE and construction?

• Abstract concepts and theories

• Dimensions and positions

• Color schemes and textures

• Legal documentation

What do scale drawings remove the need for in BSE and construction?

• The need for physical models

• The need for written dimensions

• The need for construction workers

• The need for digital software

What is a scale drawing?

• A detailed written report of a construction site

• A graphical representation of the real world, made to fit onto a piece of paper

• A full-size replica of the construction site

• A small-scale model made from plastic

What would happen without scale in drawings?

• Drawings would be more accurate

• Drawings would need to be the same size as the actual site or item described

• Drawings would be easier to understand

• Drawings would be less expensive to produce

On what does the scale that we decide to use depend in construction?

• The color of the area being represented

• The task/site and the size of the area, component, or item that we are representing

• The height of the building

• The number of workers on the site

In construction, how does the size of the area being pictured relate to the scale used?

• The smaller the area, the larger the scale

• The larger the area, the smaller the scale

• The size of the area does not affect the scale

• The larger the area, the larger the scale

What does a 1:1 scale in BSE for construction represent?

• The drawing is half the size of the item/component represented.

• The drawing shows the item at its actual size.

• The drawing is used for a component/detail drawing.

• The drawing is used where detail is required to show the actual layout of components in a particular area.

Which scale is typically used for a component/detail drawing in BSE for construction?

• 1:1

• 1:2

• 1:5

• 1:10

For what purpose is the 1:10 scale used in BSE for construction?

• To show the item at its actual size.

• To represent the drawing half the size of the item/component.

• To typically use for a component/detail drawing.

• To show the actual layout of components in a particular area.
