Benefiting from the advantages of excellent prestressed concrete
(PC) techniques, ORIENTAL Construction has been actively participating in Japan's
infrastructure projects as a leading builder in Japan's construction market since
it was established in 1952.
Prestressed concrete is prestressed using high-strength steel as tendon to add
extra strength so that it can bear a large load when used in civil engineering
and architectural structures including bridges.
About 80% of the Company's sales derive from civil engineering projects, of which
PC bridge construction amounts for 60%. More than 80% of sales relate to public
works, because our major clients are national and local government offices, including
Ministry of Construction, and public corporations such as Japan Highway Public
Working with PC structures requires an extremely high level of expertise in stress
calculation, tension control, and quality assurance. Therefore, the Company is
equipped with many skilled design and construction engineers, while promoting
development of new methods of construction, new technologies, and new products
at its Technology Research Center with cutting-age facilities. Starting around
1955, the Company also promoted the use of PC for general architectural structures,
in addition to bridges and other civil engineering works.
The Company ensures management stability through a balanced involvement in civil
engineering and architectural businesses, recognizing that a slow economy tends
to increase publicly financed civil works and a healthy economy boosts private
demand for general architecture. In addition, the Company produces factory equipment,
including crossties and curtain walls at its seven factories nationwide.
