Week 08 activity

WEEK 08 ACTIVITY: ‘IN DETAIL’ (PART ONE)  Interrogation of the detailing decisions Why they used loose insulation and what are the elements in the red circle? 

Composition Colorbond Capping and Flashing Colorbond Kliplock roof deck Drip

Colorbond Cladding Furring Channels

Wood Sleeper Roof framing, C beam insulation

100x100 SHS (square hollow section)

Capral 400 series window head

13mm Flush Jointed Plasterboard ceiling lining

 Building process The window head and plasterboard ceiling seems to be the first things constructed. Then a piece of wood sleeper is placed under the square hollow section which is one of the main structural elements. Then another wood sleeper is placed on the SHS and a concrete wall is placed on the wood sleeper. On the right side of the wall, a C beam is used to connect the roof of the building with insulation inside to the wall. Another wood sleeper is placed on the top of the concrete wall.

Two furring channels are used to attach a facade of colorbond cladding to the structural elements.

Finally the colorbond cladding and flashing is put on the top.  Pros and Cons Pros: There is a flashing roof with a drip can prevent the building from water.

Furring channel makes it easier to attach facade to the structural elements.

The Square Hollow section are beams but it is hollow so that it is lighter.

Cons: There is no waterproof for the plasterboard.

Sustainability and environmental analysis (Carbon Footprint, embodied Energy and recyclability) Carbon footprint

Embodied Energy

recyclability

Steel

Significant (Ore mined in Australia is sent to china by ships and shipped back when it is made as steel beam.

The carbon emission is significant)

Quite Large (Many processes have been made to produce steel elements)

High (Most of the steel elements are recyclable)

Timber

Low carbon footprint

Low embodied energy in processing a piece of wood into timber but high embodied energy in fostering a tree

Timber is recyclable.

plasterboard

Low carbon footprint since it is easy to make plasterboard

Medium (Not many processes involved)

Depends on the materials but these days’ plasterboards have a high recyclability.

highly

For the sustainability, materials used are very important in terms of carbon footprint, embodied energy and recyclability. The table above shows that the materials used in this building might contribute to carbon footprints but most of them a highly recyclable. Therefore the building is quite sustainable.  Economic implications of decisions The structural elements such as Square Hollow Section are chosen in a cheaper and lighter way. In terms of economic implications, the efficiency of workers are really important since labor in Australia is expensive.  Where and why things go wrong in this type of detail In 2 dimensional drawings, it is sometimes easily to get wrong. Such as the Square hollow section.

It is only indicated as SHS on the paper so if someone does not know what SHS is, he might thinks that SHS is a solid beam.
