SCREEN WALL Tower 2
Problems faced : Prior starting theScreen wall fabrication a square hollow
section of dimension (750x450x16)mm isrequired for Screen wall Vertical Columns
which isnt easily available in market and if
we need to manufacture such section it
would cost at skyrocketing price.

Solution we adopted : We created ashop drawing for the square hollowsection of the required dimension (Cutthe plate and bend it into J section and
joining the two J shaped plates into 1square hollow section with the help of
Splice Plates) which we got it approvedfrom the Consultant and Client.

Problem 2
Problems Faced : At terrace level (117mheight) about a total of 250 MT of box
columns needed to be lifted and fixed butthe problem we faced is the unavailability
of crane and due to the height factor hydra
cannot be used which is virtually impossible
to use.

Solution
Solution We adopted : Usage ofVertical Gadams and chain pulleys
having a capacity to lift 4MT waserected at Terrace and used to lift the
2.5m of Column pieces to complete the
total 16m height of each column.

Conclusion
The Structural Heavy work requires pre-
planning before performing the actual
erection on site. It involves all the aspects
of organizing resources , proper job
allocation and systematic co-ordination ,
risk assessment to achieve great results
on site.
