Intro

I’ve recently started my phase three attachment with Arup in Sydney and I’m working within the structural team on the Metro Martin Place project which involves:

• demolition of existing buildings
• tunneling for new underground rail line,
• integration with existing underground rail line
• excavation for 5 underground station levels
• construction of two towers with link beneath existing structure (current Macquarie Bank HQ).

A project which Macquarie Bank offered to deliver for NSW government in return for an unsolicited proposal.

Structural Load Take-down

One of my first tasks has been to conduct a manual load take-down for the Northern tower in order to both; produce output which will inform design and, to verify the output of the ETABs model which will be used for further analysis.

Dynamo – http://dynamobim.org/learn/

As part of my load take-down I have been asked to use software called Dynamo to provide a code script which will automatically calculate tributary areas for columns on all floors (save lots of time and enables quick auto change to calcs should design/model change) by taking data from Revit, computation in Dynamo then export to excel . Currently working with another Arupian to try figure it out as it has previously been attempted but not finished. Its blowing my mind at the minute as I’ve just started looking into it – if anyone is secretly a king coder and think they can do it then there is a wham bar in it for you…..
