| The
Mt Usher Reservoir is a 1.52megalitre water reservoir
with a diameter of 21.5m and a height of 4.9m.
A ring beam incorporating a 250mm high
nib was poured initially, and then two 2.35m high sections
were poured to form the wall to full height. The initial
wall pour used the Reflex curved wall system only, and
for the second pour, the Reflex panels were supported
on a Super Slim Soldier walkway structure that used the
tie locations from the first pour. This provided an access
walkway around the external and internal panels.
RMD's Rapidshor shoring system was
used to support soffit formwork for the roof slab and
the Rapidstage Stair Access system was used for access
in and out of the reservoir.
The Whitsunday Shire Council had used
RMD's Reflex system on a prior project (Mt Julian Reservoir)
and they were very happy with its performance. When the
Mt Usher project was considered, RMD's Reflex system was
their first choice because the Reflex panels were easy
to radius and erect, had fewer components to use and required
less labour than other systems. These Reflex features
improved site efficiency and substantially reduced costs.
The Council was also pleased with the level of sales,
technical and design support RMD provided.
