Steel Vs Concrete Frames

Question 1

Can you talk through some Advantages and disadvantages of steel frames Vs concrete

Answer 1

TIME / COST / QUALITY

BUZZ WORDS
• Time – lead & installation
• Quality – Fire, Acousitc, Thermal & gridspans
• Cost – Preliminaries

CONCRETE
TIME - Concrete has a shorter LEAD in time but longer INSTALLATION on site

QUAILTY - Concrete has better fire, acoustics and thermal properties. GRIDSPANS are shorter than steel making it more suited towards residential properties

COST - Onsite onsite construction PRELIMINARIES costs are more due to longer on site installation

STEEL
TIME - Steel has a longer LEAD time but INSTALLATION is longer

QUALITY
Steel needs to be FIRE protected and allows for larger GRIDSPANS making it

COST - fast installation so onsite preliminaries are shortened. Steel prices have gone up significantly in the last year
