Excavation for 3 Basements
Excavation for 3 Basements
(OP)
I am planning on excavating an area of 25m X 40m X 12m Deep
There is a 8 storey building located approximately 3m away from the 25m side
What precautations can / should be taken to prevent the pit from collapsing and the tall building from falling!
Any assistance on this will be much appreciated

It was the 3m away from an 8 storey building that ran up the red flag... Reminds me of the condo in China a year or so back...

Red flag because it was in China?
I agree - get a geotech.

If your firm has not done anything close to this complex project, it maybe wiser to pass it on to more specialized structural firm. Sometimes, saying "no" is necessary. Good luck.

Do you have insurance? It probably won't do any good

If you had to ask the question, you probably are not qualified to design the support system and this isn't the job to learn on.

In order to "wish" the new construction into place, a contractor will need to do all sorts of stuff that's fundamentally temporary. This may include shoring of existing utilities, shoring of excavations, use of temporary excavation bracing, etc. It's best that you let the contractor do what the contractor is obligated to do and focus on the engineering that's required for the owner's interests.
Yeah, I'm aware that there is a great geotechnical effort to design temporary excavation bracing for the contractor. I think it's very interesting. I just want to reference that there is a division of responsibility to consider in these sorts of questions.

Building with Deep basements are now becoming the norm here as space is expensive

If you do not have experience with design of below grade walls then you should consult with another architect. A mistake in the design of the drainage system can be difficult to repair.
