Pop Quiz – Come and have a go if you think you’re smart enough!
Fellow Engineers,
Todays challenge in the office is to calculate how much steel (by weight) is in the abutment for the Gladstone Jetty. To assist you, you have the following drawing only:
This competition is open to everyone (including PEW staff).
E&Ms, this is quite advanced so you may not want to enter this challenge!
Ros, you should come top of the class based on your project!
Answers as soon as possible to help me out!

We of the Adelaide Superhighway laugh at your measly scraps of reinforcement……
Generally for pile caps – if you’re guessing you go from 100 to 150 kg/m3 of concrete
For ground beams this rises to 200-250 kg/m3 or so.
Given that the drawing has almost no dimensions – I’ve had to guess these and come up with 107kg/m3
So I laugh even more….given that the values Ros is dealing with must be astronomical…..keep up the guesswork.
BTW the head shear detail is unusual here. You’re going to have to weld those rings into the inside of the pile shells – after or before driving? Then it seems that (Detail 1) the pile fill is left low and a blinding placed (?????) Then the headstock is cast into the internal shear key….Not seen this before.
John, I was sat with a scale rule on Monday trying to get my head round this. Best of all is that I had a copy printed on A3 paper, it’s an A1 drawing and clearly states “do not scale” on it! Mega!
Your entry into the competition is acknowledged and I suspect you may be the winner unless anyone else enters!
The answer won’t be given until May/June when we actually build the bloody thing and I can actually tell what is being put in there!
Step 1 email Arup and ask for the bar schedule. Step 2 produce your own and work it up from there. Step 3 Issue your ‘estimate’ to Arup for confirmation – the design responsibility rests elsewhere and the drawing is not for construction. This is a task a decent technician will do for you in half a day but that you need to check and for which you then take resposibility…
Richard, unfortunately the bar schedules here do not get produced by the designer(s) and are the responsibility of the steel supplier! Barking mad I know. I smashed it out though and came up with some figures that were in the right ball park so all is well.
