Dear Engineers,
Please see the following and provide your valuable response. Thanks.

Speaking of bundled bars, I did a renovation, decades back, on a building that was pre-WWI. Bot bars were bundled. They were 'twisted' square bars. They still had the wire wrap and the metal identification tag connected.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Because your pile cap is so deep, it will have little impact on the overdesign caused by the reduced depth... not to worry, one way or the other

Hturkak.
Thank you for your descriptive response.
You are right about the source of the figure.
Our Office used to practice 'no cover above pile top', recently it's started to practise some 3"clear cover above the pile top. I think 3" is a lot, office says pile cap reinforcement should have some clean concrete at all locations.

I thank everyone for sharing your practical knowledge and preferences, it is of great help.
