Early breakthrough
for TBM
A
Robbins Double Shield TBM working in the Himalayas mountain
range has broken through about one year ahead of the overall project
schedule, and seven months ahead of the tunnel boring machine
(TBM) tunnelling schedule.
The 5.06m diameter TBM achieved over 1,000m monthly advance on
two separate occasions and averaged over 700m per month over the course of
tunnelling.
The machine completed the 12.2km Bheri Babai Diversion Multipurpose
Project (BBDMP) for the Government of Nepal’s Department of Irrigation
(DOI) and contractor China Overseas Engineering Group Co. Ltd. Nepal
Branch (COVEC Nepal).
The machine’s completion of the tunnel in just 17 months came nearly a
year ahead of the DOI’s deadline for completing the tunnel of March 28, 2020.
When the BBDMP was fast-tracked as one of the country’s ‘National Pride
Projects’ feasibility studies showed that Drill & Blast excavation of the tunnel
could take as long as 12 years, with TMBs offering a faster option.
The project began working with local Robbins representatives MOSH
Tunnelling to bring what is said to be the first Nepalese TBM into the country.
The tunnel is located in the Siwalik Range, part of the Southern
Himalayan Mountains, where geology consists of mainly sandstone, mudstone,
and conglomerate. Once the BBDMP is operational, it will irrigate 51,000
hectares of land in the southern region of Nepal and provide 48 MW annual
generating capacity. The estimated annual benefit of the project is US$64
million.

I
t has been estimated by the US
Association of State Dam Safety
Officials (ASDSO) that more
than US$70 billion is required for
dam restoration. Across the US there
are more than 90,000 dams. The
ASDSO has said that an important
step towards reducing these costs
is creating and supporting funding
assistance by the federal government
and individual States.
Currently, lack of funding for
dam upgrades is a national problem,
especially within the private sector.
Unlike most infrastructure facilities,
the majority of dams in the US are
privately owned, leaving owners solely
responsible for financing dam upkeep
and upgrades.
Without proper maintenance,
repair and rehabilitation, the dams
may become unable to serve their
intended purpose and could be at risk
for failure.

hyssenkrupp Infrastructure
GmbH is supplying materials,
engineering equipment and
components for the foundations
of the first nuclear power plant in
Bangladesh. In Ruppur, 180km west
of the capital Dhaka, the first national
nuclear power plant will secure energy
supplies in Bangladesh from the year
2023. Ruppur was selected partly due
to its proximity to the Padma river,
which will supply the cooling water
for the planned power plant.
With a total of three vibration
units and over 1,200 tons of ASF
anchor piles with a diameter of
640mm and a thickness of 90mm,
Thyssenkrupp Infrastructure is
contributing to the construction of
the foundations. The vibrators are a
müller MS-50 H3 with MS-A420 V
and a müller-100HHF with MS-700
V for installing pipe lengths of 17m
and a diameter of 630 and 1020mm.
In order to get up to 37m long
pipes into the subsoil, an even more
powerful vibrator was said to have
been required.
L
eading French rental company
Kiloutou is now including
drones in its offering.
The company has made this
move in recognition of the fact
that drones are increasingly being
used for various surveying jobs
on construction sites because they
provide a safe way of collecting
a large amount of useful data.
For instance, they can capture
photos, videos and thermographic
information for use in 3D models
and photogrammetry.
Drones must, however, be
operated by qualified pilots. In
France, an exam must be passed
with the French Civil Aviation
Authority (DGAC). For this reason,
Kiloutou offers a complete package
that includes the drone, sensors and
a pilot.
T
he result of the Indian general
election has been decided,
with Prime Minister Narendra
Modi’s party, Bharatiya Janata (BJP),
gaining a landslide victory to win
re-election. This result should see
large investment in infrastructure
development continue across the
country. Modi’s government has
invested record amounts into
infrastructure since 2014.
As part of Narendra Modi’s
re-election campaign, the party
pledged to spend US$1.44 trillion on
infrastructure to boost the economy
and raise living standards, in a bid to
match its main rival’s promises.
In the BJP’s manifesto, this target
of INR100 trillion (US$1.44 trillion)
will be invested by 2024.
The BJP plan to build roads,
railways and other infrastructure,
offer a boost to manufacturing, and
double exports. These promises, along
with tax cuts for middle class Indians,
appeared to resonate with voters,
helping the BJP win a large majority
of the seats in parliament.

lobal cement consumption
is expected to remain at its
current level of 4.01 billion
tons (3.63 billion tonnes) by 2050,
according to an update of the Global
Cement Volume Forecast Report
from CemWeek Research.
Cement consumption is expected
to decline in China; the country has
reached a demand peak of 2.3 billion
tons (2.09 billion tonnes) accounting
for more than 50% of demand
worldwide. Cement demand will
see moderate gains though in both
developed and emerging economies.
Growth is also likely to be
challenged by factors such as
environmental restrictions, substitute
material and new construction
methods. There is also likely to be
increased usage of alternative building
materials including low-clinker
cement, alternative fuels, and precast
concrete.
