Project Description

A single storey $($Ground Floor and Roof$)$ bespoke house is required to be built in Auckland. The build$-$

ing should have size and layout as given in Figure $1$ and Figure $2,$ there must be $2\mathrm{.}8m$ head room

within the building. Subsoil profile is $C$ according to the geotechnical report. The building is to

be built on a plateau with a $30$ slope escarpment to provide panoramic views. To facilitate this, no verti$-$

cal structure $($columns or walls$)$ are permitted along the viewing elevation, which is to be glazed full height

$.$ There are no limitations placed upon the floor$/$roof structure size, but client's requirements are to have

open plan living spaces. The roof structure is expected to form a key aesthetic element of the building. The

Architect wishes to use steel as the only material for the building and therefore the structure will be fully ex$-$

posed internally and externally. Your submission must state and justify, any further assumptions made. A

client requires a $100$ years design working life for the proposed structure.

Drawings are to scale but DO NOT scale these. All units are in $m$ unless noted otherwise. As part of pre$-$

liminary design select the structural system and floor$/$roof slab system and justify your choice. The grids on

the perimeter of the building support concrete panels and$/$or glazing units. Appropriate detailing con$-$

siderations for wind resistance need to be considered. steel grade is $300$ plus; Roof finishing over slab $($com$-$

plete with insulation, screed and clay tiles$),5\mathrm{.}0k\frac{N}{m^2}$; floor finishing $($incl$.$ granite tiles, screed, and al$-$

lowance for partitions$)=540k\frac{N}{m^2}.$ In addition to permanent actions, you may also need to consider loads

from finishes, which can be calculated using the following tabulated material densities.
