The
large supporting column is erected early in the morning of September 15.
|
View of the column -- comprised of thick plates welded to form a square section. |
View
looking up the supporting column -- bracing in view. This is a massive
custom column comprised of 4 - 3" thick steel plates welded together
-- 19 metres tall! |
This
column stub that extends from the concrete structure will accept the western
end of the truss. |
The
ironworkers attach the cables to the truss for the first lift. This lift
will take the truss off of its temporary supports that were put beneath
the truss to allow for on site connections to be made. |
The
crane lifts the truss off of its temporary supports. |
The
truss is placed back on new supports to allow the secondary lift connections
to be placed. |
Connecting
the lifting cables to the secondary lift connections. |
Close
up of the lifting connections. |
The
truss is lifted/rotated into an upright position -- ready to go. Meanwhile
the traffic is stopped on College Street adjacent as the truss will swing
over the street for a few moments in order to be in the correct position
and to clear on site trees and the concrete columns that are already in
place. |
Truss
in the air! |
The
truss must be carefully positioned by the crane operator. Three points
of connection must be achieved: at the column on the building; on top
of the steel column; and into a connection along the length of the column. |
The
truss hovers above the connection at the steel column. |
Ironworkers
work towards getting the truss in the correct alignment to make the connection
at the building. |
A
ways to go... the ironworker holds a connection that appears to be around
30" from alignment at this point. |
Working
towards making the mid span connection a little closer... |
An
ironworker sits astride the mid span connection, checking for alignment. |
The truss is finally in place! |
