Modular Or Perfabricetd Construction Flashcards
What is modular construction? 
It is the term used to describe the use of factory produced pre-engineered building units 
What are the 6 main sectors of application for modular construction?
Private housing, social housing, educational sector and student residence, public sector buildings, health sector buildings, hotels
What are the 4 types of modules used in the design of buildings?
4-sided modules
opensided (corner supported) modules
modules supported by a primary structural frame
stair or lift modules
What are 4-sided modules?
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
What is the usual approximate height of buildings with modules and what can they be manufactured with?
Height ranges of 6 to 10 stories, depending on location and exposure to wind action
With integral balconies and a range of cladding materials
What 2 things is the cellular space provided limited by?
Transportation and installation requirements
What are the 6 benefits of modular buildings?
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
What are open-sided (corner-supported) modules?
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
What is the open-sided module framework is often formed of?
hotrolled steel members that are bolted together.
What are 2 examples of hotrolled steel members?
Square hollow section columns (SHS)
Parallel flange channel edge beams (PFC)
What can open-sided modules be placed side-by-side to create?
Modules can be placed side-by-side to create large open plan spaces
What does the stability of the building generally rely on? (Open-sided)
A separate bracing system in the form of X bracing
Because of the bracing system, fully open-ended modules are NOT often used for…?
Buildings more than 3 storeys high
What 2 things could be used to fill in the non-load bearing wall?
Infill walls and partitions within modules
Modular units are designed to be supported by a primary structure at what level?
A podium or platform level
What are the beams designed to support (primary structure)?
The combined loads from the other modules (normally a maximum of 4-6 storeys)
What 4 purposes is this form of construction suitable for?
Mixed retail
Commercial/residential developments
Especially, residential units above commercial areas or car parking
Particularly in urban projects
Modules can be disassembled in the future to…?
To leave the floor cassette supported by the beams
Modular stairs may be designed as fully modular units, they generally comprise of…?
Landings and half-landings with 2 flights of stairs
What are the landings and half-landings supported by?
Longitudinal walls with additional angles or SHS
What do the longitudinal walls with additional angles or SHS provide?
Local strengthening
What can the open top and base of the wall be strengthened by?
A “T “, “L “ or similar members
What can be introduced into the walls to provide overall stability?
SHS posts and bracing
