Question 3

What are the 4 types of modules used in the design of buildings?

Answer 3

4-sided modules
opensided (corner supported) modules
modules supported by a primary structural frame
stair or lift modules

Question 4

What are 4-sided modules?

Answer 4

4-sided modules are basic building blocks that have four closed sides or surfaces. They can be used to construct a variety of structures and objects by connecting several modules together

Question 5

What is the usual approximate height of buildings with modules and what can they be manufactured with?

Answer 5

Transportation and installation requirements

Question 7

What are the 6 benefits of modular buildings?

Answer 7

Rapid installation
high level of quality control in factory production
suitable for projects with site constraints
Useful in building renovation projects
excellent acoustic/thermal insulation
adaptable for future extensions and ability to be dismantled easily removed if required

Question 8

What are open-sided (corner-supported) modules?

Answer 8

Modules that have at least one side that is open or lacks a surface. These types of modules are often used for creating structures that require accessibility or visibility from one or multiple sides

Question 9

What is the open-sided module framework is often formed of?

Answer 9

hotrolled steel members that are bolted together.

Question 10

What are 2 examples of hotrolled steel members?

Answer 10

Square hollow section columns (SHS)
Parallel flange channel edge beams (PFC)

Question 11

What can open-sided modules be placed side-by-side to create?

Answer 11

Modules can be placed side-by-side to create large open plan spaces

Question 12

What does the stability of the building generally rely on? (Open-sided)

Answer 12

A separate bracing system in the form of X bracing

Question 13

Because of the bracing system, fully open-ended modules are NOT often used for…?

Answer 13

Buildings more than 3 storeys high

Question 14

What 2 things could be used to fill in the non-load bearing wall?

Answer 14

Infill walls and partitions within modules

Question 15

Modular units are designed to be supported by a primary structure at what level?

Answer 15

A podium or platform level

Question 16

What are the beams designed to support (primary structure)?

Answer 16

Especially, residential units above commercial areas or car parking
Particularly in urban projects

Question 18

Modules can be disassembled in the future to…?

Answer 18

To leave the floor cassette supported by the beams

Question 19

Modular stairs may be designed as fully modular units, they generally comprise of…?

Answer 19

Landings and half-landings with 2 flights of stairs

Question 20

What are the landings and half-landings supported by?

Answer 20

Longitudinal walls with additional angles or SHS

A “T “, “L “ or similar members

Question 23

What can be introduced into the walls to provide overall stability?

Answer 23

SHS posts and bracing
