Deep sea release, cofferdam construction
Barclay Mowlem Candac
in alliance with Coffs Harbour City Council is in the final stage
of its design and construction of a reclaimed water deep sea ocean
release off Boambee Beach at Coffs Harbour.
A temporary trestle was built across the beach to allow construction
of the pipe under the sea bed through the surf zone until the water
is six metres deep. To date, thirteen pipe sections (approx 240
metres) have been laid adjacent to the temporary trestle using
a sheet pile cofferdam. The pipe-laying started at the seaward
end of the temporary trestle and the cofferdam has been progressively
moved in towards the beach.
BMC used two PTC vibratory hammers throughout the project – their
own 25H2 and Steelcom’s new 30H1.
