Building the Buoy: CONSTRUCTION

We started construction 9am thursday and wrapped up 5pm friday.


Our main 'construction' was the collection of water directly from the public marina in front of our site. We used a surveyors pole to measure the different depths taking samples from the surface through to 2m below.

We then pumped directly into the structure via a lookout across the public thoroughfare to alert the public of the trip hazard. This time was also used to test the structural integrity of the main wall. In the above iteration the wall is a tight stretcher bond however the foot and lid system of the boxes meant that this arrangement could not lock into place and therefore could not withstand any horizontal pressure (much like a Jenga block configuration).

At the same time we began to test the moveable wall, assessing the added windload of the bags and established that the best arrangement was alternating rows on the front and bag and staggering the distribution along the rows.


1500 sandwich bags and 3000 mini pegs is a time consuming but safe and therapeutic construction method. Pretty sure there is not a single mini peg left in the greater Melbourne locale!

As the construction starts to come together, unexpected effects appear.

Here the two construction systems, side by side, show the rigid order necessary to maintain the structural integrity. As you can see, the solar lights are distributed throughout the stacker wall, all within the same sandwich bags as the moveable wall.
