The scope of public investment has increased with the
development of new forms of transportation and the rapid
expansion of road and rail networks in Japan in recent
years, enabling us to carry out constructional work in
such areas throughout the country.
We are now ready to expand these activities into overseas
markets on the basis of techniques we have developed and
the experience we have gained,
The products which we wish to build and supply are those
which meet the needs of society. Products which are of
outstanding quality, yet low in price because they have
been made efficiently and well through the application
of advanced technologies.
In 1998, we obtained the ISO9001 international quality
standard in relation to bridges and water gates. |

In order to win customer confidence, and assisted by leading
authorities, we have increased the size of our construction
work and have teams constantly studying the latest developments
in bridge construction, including very long-large bridges.
The construction of extra-long bridges has increased rapidly
in Japan in recent years through development of the "Large
Block Construction Method", which has enabled the
construction of bridges connecting the main roads of several
remote islands. One such bridge is the Ikitsuki Bridge
in Nagasaki Prefecture.
The company has also constructed many small and medium-sized
bridges, railroad bridges, pedestrian bridges, aqueduct
bridges for water resources development, floating pontoons
for car ferries, steel bridge piers and other special
structures. |

Dams supply the water for hydraulic power generation
and to meet the demands of the public water supply
for agriculture and industry, , all of which are
indispensable to economic growth and human life.
Hydraulic gates and steel penstocks play an important
role in the control of flood waters, water-utilization
schemes and flood-prevention for the control of
water intake, and the prevention of and protection
against high tides and tidal waves.
We have already constructed a large number of these
items to date, and won official commendation from
the Kyushu Regional Construction Bureau, Japan for
the excellent construction work we performed on
the crest gates for the Yabakei Dam Project.
Moreover, we intend to improve our standards of
technology by developing super-high pressure gates,
surface water intake gates and larger diameter steel
penstocks and manifold pipes.
At the same time, we have been steadily expanding
our foothold in Southeast Asian and South America
and have already carried out projects in those areas.
An example of one of our extra large projects is
the Indonesian Cirata Hydroelectric Power Project,
in which 4,940 tons of steel was used; 2,440 tons
for the steel penstocks and 2,500 tons for water
gates and similar items. |
