I did some study on your layout plan... your span is 24ft width... that is a big span if you want a free column design... bigger width means, bigger beam size...im assuming your beam size is only about 300 clear-450mm thick/ height... so required column between the 24ft width..... and there is a reason why the previous structure engineer design that position that way.... you cant simply remove the existing column....
even if you hire a structural engineer.. he may ask you to design a new column and beam ...not effecting the existing ones.. unless you gave the original developer structure engineering drawings.. than he can study the original design calculation and the rebar /link concrete type size applied to the unit......then and only then you demolished the certain column......

worst case scenario..... incorporate I.D features.... or redesign the layout surrounding the column... start to play around with the spaces.....

new developers or new development should provide all this info to owners.... only structure related to your unit..
if got old2 development...a bit difficult to get....
they must provide you if you doing major renovation works... sometimes you need to apply or request from the appointed management team or from the developer....
what is the drawing called ? -

Structure drawings.
1) Foundation Layout plan
2) Ground floor beam plan
3) first floor beam plan
4) roof floor beam plan
5) foundation reinforcement schedule
6) column schedule.
7) beam / slab detail....

hope this helps

Oh sorry , I thought you ask related to structure drawings …

Well .. if you are planning to start a renovation - a major renovation…. You can request this drawings ….

1) electrical schematic diagram -for your future electrical contractor to study and at least a guideline for them if want to do looping / or direct to db wiring works …

2) architecture/building schedule finishes(exterior and interior)
( including the codes and batch no ( for tiling if can )

3) sanitary & plumbing schematic diagram ( sometimes got contractor just bulldoze and hentam only Paip connection and end up leaking all over the place ..

4) architecture plans section elevation ( normally they will give you basic measurements - not detail. )

5) the structure drawings I mention ..

I think that’s about it …


Hope this help
