Dear Thananan,
a) Please explain why desired height is 3.9 m instead of 4.1 m as shown on KONE’s drawing?
b) The passenger lift level at Mezzanine floor is messed up again. The top of steel members are FFL (+7.40) + 4.1 (clearance) + 0.50 (Type E height) = +12.00.
c) Please also revised the elevation line D and line E, gridlines 4~5. Please note that TOP and SOFFIT are two different things.
d) I commented to note on the soffit levels for car lift and passenger lift so that you provide enough headroom from 3rd floor FFL.
- - For car lift, FFL (+7.30) + 4.9 (KONE required clearance) = +12.20 (soffit of beam Type E). Hence top of the steel is +12.70.
- For passenger lift, FFL (+7.40) + 4.1 (KONE required clearance) = +11.50 (soffit of beam Type E). Hence top of steel is +12.00.
e) Your descriptions of beam soffit levels of +10.50, +10.625, +11.70, +12.70 has errors and creates more confusions. Kindly delete it.
Thank you and regards,
Marcus Mok
