DESCRIPTION
TRANSCRIPT
During this activity we were asked to construct the tallest tower out of one piece of balsa wood. Our group began disadvantaged as our balsa wood was cut too small so we were required to join three small pieces into one larger piece. Due to our added joints our structure became unstable and was not able to support itself. When forces are applied
(even self weight) it causes the structure to deform and is unable to support itself.
Queen Elizabeth Olympic Park • Cleaning soil onsite is a alternative way to remove contaminated soil • Landscaping was the key driver, the notion of play and leisure time. It is a productive landscape, not just pretty to look at • Cheap ways to change the space over time – used rubber to fill in a space while it was being used, it could then be reused in another form
afterwards. • The main space had eight bridge connected to it • The stadium is a series of rings, it was created in a well (an amphitheater)
it was a very simple structure • Transformation and change over time • The stadium was bolted rather than welded so that it could be transformed • During the event the aquatic centre had wings applied to it to add seating that was taken away and dismantled at the end • It required a pumping station, a power station – used brick to contrast against the light other materials.

Example of a cantilever (one point of support)
Example of a tensile structure – the poles that are creating the tension are held in the ground by concrete
Car park under south lawn. Columns created to ensure tree roots are not interfered with
Example of both an expansion joint and a weep hole
When this building was built it did not allow for the expansion of the bricks. An expansion joint had to be created after construction
Cantilever being constructed on the architecture building
Frame structure. The frame is easily visible.
Looks like a tensile structure but is actually being supported at the base by beams.
• Project architect: working closely with the consultants and continue to work with the client • Structural engineer: make sure the building all works -‐ lights, uv • Types of engineers: mechanical, hydraulics, civil, electrical (power points), ESD, structural (the skeleton) • Project manager: client side of project manager – represents Melbourne university sports for privilion. Makes sure client is happy and their brief is fulfilled. Appoint the technical experts that will design and build the final
• The existing building meant there was not just a blank canvas. It had to be understood and respected before any other designs could be thought out. • Used timber for the vertical and steel for the horizontal – a hybrid
• The basement had to be durable (this is the major criteria) – used concrete as this will stop the water penetrating through
• Everything above the basement is made out of light weight materials • Make sure the design is visible – it is within the clients budget so there is enough money to fund the project • The rushed design period – had disgruntled users of the original area • Delayed by council because of the heritage listings – had to employ a heritage architect to help relieve • Had to reroute power cables so they were able to get into the basement – had to apply to city power for this • From the outset the architect and client knew that they were not doing a reproduction • Dealt with the heritage using scale
• All come together with a number of different skills

Concrete insitu • A cantilever is not one when it is being built – there are props
underneath • Retension system when • Reinforcing cages – lowered into the hole • Concrete is poured – reinforcement still sticking out the top • Put reinforcing in top – tie all of the board peam together • Concrete poured directly from concrete truck • It can then be exuvated and this will ensure that no soil will fall back
in
• They will then pour the slab – concrete slab • They use suspended formwork to create the slab on ground floor Concrete pre cast • It is cast down flat – needs lifting tools • Stacked vertically and then transported to the site • Precast coloums need props – walls need at least two props • Need to make a connection – these need to be casted into the
concrete
South side – polished white concrete Steel • Steel in the roof • Main structural steel holding the roof up Cantilever • 12 metres out from the building • the structure has to be trinangulated • you have to wait until the building is up before you can begin the

Week Five: Tutorial
We began by building the basement part of our structure. However, we made the mistake of including the walls rather than just the structural elements.
We then learnt from our mistakes and on the ground floor only included the beams and columns
We ensured that the different height levels were depicted, as seen here when we placed a beam
We did not completely finish but we included the major beams and columns and even within the basement

UC beam supporting the floor above – three layers of brick above (couple of tonnes)
Scaffolding required when there is a drop of a certain height. Opening in the floor require a scaffold too.
The original bricks are quite rare and whenever something inside is demolished they are saved for reuse
The original insulation is rotting so it is being replaced. The orange wire is high voltage
The finials on the roof are being installed. Similar to the ones the building would have originally had
Cement sheet is used on the walls with metal framing
1880 Primary School Being transformed into a community center (library at the back) -‐ Steel frame -‐ Heritage (heritage act 1986) -‐ Heritage vic = state level -‐ Local heritage overlay = planning à street scape
The bathroom is set down to allow for waterproof and tiles.
Props: each panel has to have two solid connections at all times.
Piles: they are another 12 metres underground. Has a cage in the middle
Display suite. This is due to the apartments being sold before the building is complete
Precast concrete has different finishes and textures
Back propped every two and a half metres. Needs to be done before the concrete is poured

Construction Workshop
In the construction workshop we were required to create something that spanned across a meter using already selected materials. For our structure we decided to create a truss to help support the weight with a lining as well. We were originally going to test it laying horizontally flat but decided in the end to test is standing on its side. When the structure was test it deflected 25 millimeters and a 320 kg weight was applied to it before it failed.
