The ORIFICE culver of Kampung Tanaki, Penampang
In situ concrete box culvert under construction but terrible workmanship
PENAMPANG. A flood-causing concrete culvert pipe less
than 1 metre diameter under a high embankment road at Kg Tanaki here, is
finally being replaced.
Installed
when the road was built about 3 decades ago, crossing a rivulet in the
village, the undersized culvert bluntly called "orifice" is not to JKR
specification, hence easily clogged causing flooding upstream. Pic 1.
Daily
reported the village was still flooded under hot sun on 16 February
when Member of Parliament Datuk Ewon Benedict and Kapayan Assemblywoman
Janie Lasimbang came to inspect after being informed by the residents.
The
upgrading works though welcomed is causing massive traffic jams during
peak hours, though temporary may still take 2 months to complete.
Residents nearby said its unnecesary waste of time and taxpayers money
compared to installing the proper culvert size earlier. In addition,
excavation and filling up of a good road also damaged water pipelines to
the villagers.
Tunelling under the high road embankment is either too expensive or technology not available, a netizen said.
Adding
further worries, the in-situ casting of a concrete box culvert by a new
contractor is described as "Very Bad Workmanship" by retired JKR
engineer and an experienced contractor. As seen in pic 2, the
concreting seemed to be mixing with soil while the two layers of BRC
reinforcings have no spacing. Hence the concrete cube test taken on site
is meaningless, according to another engineer.
Netizens
are also asking how long will this new culvert last before collapsing.
They also request the government to monitor all other culverts being
installed especially the Pan Borneo project which has been alleged to
cause floods.
