PROJECT SYNOPSIS VOLUME 1/
SECTION 1
Ambient Air Quality: Laden with coal and steel dust particles, fumes,
chemical gases.

1893:2002, Seismic forces would be considered as per the IS Code
accordingly.
1.4 Wind loading
The various design parameters, as defined in IS: 875 (part 3), to
be applied for the project site shall be as follows
(a) The basic wind speed “Vb” at ten mtrs above the mean
ground level – 47 m/sec
(b) Other parameters or coefficients shall be as per IS: 875 (part
3) stipulations.
1.5 Construction Material
It is expected that all necessary construction material should be
