Steel roofing trusses weighing about 100 tonnes each have
been lifted into place at the Forsyth Barr Stadium in Dunedin,
and the lift of a massive 700-tonne main truss may go ahead in
the next couple of weeks.
Dunedin Venues Management Ltd development director Darren
Burden said the first "prismatic" truss, straddling the gap
between the column and the main south stand, was lifted into
place on Sunday, and the second yesterday.
There had been good progress on the main truss, which was on
site, and being bolted together on the site of the stadium's
Once the two pieces of steelwork were secured, the columns
would be able to support the main truss, which would span the
gap between the two columns, Mr Burden said.
The lifting of about 700 tonnes of steel into place 35m above
the ground - one of the most difficult stages of the project
- was understood to be the highest such a weight had been
lifted in New Zealand.
Hawkins Construction senior site manager Dave James said last
year the lift would take up to seven hours, and require two
400-tonne cranes lifting at once, with pinpoint
co-ordination, on a day with no wind.
Mr Burden said yesterday the lift was to have been carried
out late this month or in early June, but that target had
"shifted a little bit", and may now be about the middle of
The timing of the lift, though, depended on calm weather.
The transportation of steel for the roof, involving hundreds
of truckloads, was still going on, but all of the steel
required had arrived in the country, and a significant amount
had been fabricated.
The roof structures for the east and west stands would be the
next stage of the roofing work.
The planting of the stadium's turf was scheduled for January
next year, and the ethylene tetrafluoroethylene (ETFE) roof
had to be completed to a point the pitch area was cleared by
