Telecom infrastructure development:
Sierra takes another step forward
Sierra Global Network (Pvt) Ltd., a leading firm in the
telecommunication infrastructure development sector has taken another
step forward by implementing fibre optic cable projects using the
Horizontal Directional Drilling, commonly known as HDD technology.
Director/CEO of Sierra Global Dr. Arosha Fernando discusses the
benefits of HDD technology with senior representatives of Bharti
Airtel and the Colombo Municipal Council (CMC) during a
demonstration held in Maligawatte. The HDD machine is at right. |
HDD is allowing construction companies to install underground
telecommunication network infrastructure minimizing or eliminating the
need for excavation. In most developed countries this trenchless
technique has been used to install underground ducts along the roads as
an alternative to traditional digging techniques.
Long installation lengths can be achieved (even up to several kms) by
dividing the work length into shorter sections (100m - 200m as an
average). The length of each section will depend on the characteristics
of the machines and the design requirements.
Director/CEO of Sierra Global, Dr. Arosha Fernando said, “After a
series of successful demonstrations, the Colombo Municipal Council (CMC)
and Road Development Authority (RDA) and a number of telecommunication
operators approved and appreciated the usage of HDD technology
considering its direct benefits.
HDD technology will reduce environmental damage and social costs and
at the same time, provide an economic alternative to the traditional
open-trench methods of installation of fibre optic cable.
In early days, rivers and railway crossings were the first
applications of this HDD technology due to the fact that traditional
digging techniques were not suitable. However, in developed countries
this new technology has been mostly used today and in some countries it
is compulsory to use only this technology in any of the fibre optic
cable project”.
“This minimises even up to 95 percent damage to the roads since
construction will be underground in most of the construction length
which is a great benefit especially for countries such as Sri Lanka”.
Sierra has been involved in construction of underground
telecommunication network infrastructure for the past 28 years and has
always been maintaining the leading market share in this segment.
Sierra obtained the expertise training of HDD by sending its senior
engineering staff to Canada where theoretical and practical aspects of
HDD were ascertained. In the past Sierra has successfully used the HDD
technology to implement telecommunication fibre optic cable projects in
a number of overseas countries including India and Australia. |
