Concrete and Reinforcing
construction time and cost savings when using Aertec AAC
Aertec completed a 6 storey student accommodation project called '4 on Nursery' where AAC was specified for the external hybrid cavity wall and all internal partition walls. The structural frame consisted of reinforced concrete, supported on 9m deep piles. The structural savings as well as time related savings can be found in the table below, when compared with conventional masonry:
Concrete and Reinforcing, construction time and cost savings | |
Foundations: | 21% |
Slabs: | 27% |
Columns: | 35% |
Construction time reduction: | 48% |
Total cost saving: | 21% |
