Actually, beside that, do you provide BQ as well?

IMHO, those who don't provide details . Is for those for looking for short run in this industry. For those who already in this industry. They will started to realize , when it time to come. Some job or project even is good margin also is not happen in great timing for them. Don't over too insist on "fabrication" process that see money.
For details drawing, beside avoid any dispute on renovation . It also is a tools for owner to make bargaining . Request for final 3-5% discount. It also a schedule for owner to measure when their is the right time for owner to move in.

As An ID, we also a person who actually side for owner to make the best savings, deal ,outcome . This mentality can help for long run person. Your credit will be appreciated.

I'm pay my respect to you. Please keep your professional on this industry. Your works and input will bring this industry to better future.
*I'm not pointing anyone in this comment, if feels disturbed. I'm apologize for it.
*I'm not a person who can draw, but I'm leading the team who can draw. I know how the process on drawing.
** I'm was being in the same situation like TS before, I was like

" WTF! Like this also can charge Rm 8k for 6 sheet of 3D views,no details how to do o ?, if you want see 3D only . Come find me next time, 1 view I charge rm 500 only. "

A lot of IDs just give 3D drawings to impress buyers. And in this current times, buyers are not educated with the knowledge that an ID should also provide with more detailed drawings, until you explained here. Furthermore, a layman like us would not know how to decipher a technical drawing, which then makes the detailed drawings irrelevant. It's good that Adrian educates us here on this professional ethics. Nowadays, a lot of businesses lacks ethics...
