A Message from the President

Established in 1947 as a firm involved in the foundation work for dam,we at Nittoc Construction have since been producing many outstanding records in a wide range of civil engineering works for dam,river,road,sewage,water supply and land development.

In our Nittoc,large numbers of professionals are enrolled respectively as civil engineer,geologist and other specialist,who are also richly experienced in the actual on-site construction works.To meet the requirements of the days,they have been working hard to develop a variety of innovative technologies and to create related engineering methods or applications in the sphere of "Environment,Disaster Prevention,Renovation and Maintenance",the very area of expertise the company has been offering to date,in particular.

Displaying all the collective strength upon the united teamwork between the technical or technological staffs and those involved in the actual on-site works of engineering for the foundation,slope stabilization,soil improvement,geological survey,etc.,we at Nittoc have also been working hard to offer the services of high quality under the authentication of ISO9001 as the "General Contractor excelling at a Certain Specialized Civil Engineering Work".

The construction is now under a very harsh climate in the business we've never been experiencing before,while the social needs for national land conservation,preservation of natural environment and furthermore,reinforcement and maintenance of infrastructure have also been increasing more and more in recent years.

We at Nittoc look on such harsh circumstances as a good opportunity for further development in our business and thus,exert ourselves to solidify a company's business foundation and at the same time,make our best efforts to aim at a highly reliable company in the society by offering the original technologies we possess to be applied faithfully to the works.

CORPORATE HISTORY

In 1938, the construction of Uryuu Dai-ichi Dam for a huge water reservoir with its reservoir capacity of 240 million cubic meters started to be laid down at the foot of Mt.Taisetsu in Hokkaido. The dam was that of a gravity-type concrete structure with 45.5 meters in height and to lead the project securely to a successful completion, extraordinary energies were poured into the then technique or technology for disposal of the breccia-conglomerate at the site of foundaton.
A variety of innovative technologies accumulated to date in our Nittoc originated for a start exactly in this project.

Under the then heyday of the construction of dam-type hydroelectric power plant in the 1950s to meet the development of power resources, the company established in 1947 took the intiative in creating the relevant technologies to start as a civil engineering firm specializing in the dam foundation works. The innovative technologies thus developed, the collective strength, in particular,of which comes to be displayed thoroughly under the close collaboration between the civil engineer and geologist involved in, have since been highly appreciated by those who concerned in the industry. The company has thus been involved in almost all of the foundation works for huge dams laid down here in Japan including Kuroyon Dam at the outset.

Aiming at the general foundation-integrated firm to cope with the then coming age of technological innovation, the company was positively grappling with the foundation works for the rail roads of the Shinkansen (the Bullet Train), expressways, buildings, etc., and has through such works produced a number of outstanding achievements.

In 1972, the company was renamed to the present Nittoc Construction Co.,Ltd. Taking this opportunity, the company actively promoted
the expansion of its businesses, which now cover the construction of dam itself, civil engineering works for shore protection, river, road, water supply, sewerage, land development and construction of buildings, and thus, has accumulated a variety of core technologies and know-how through such a wide range of construction and engineering practices together with a number of outstanding records.

In 1983, the company was listed in the Second Section of the Tokyo Stock Exchange, which was then followed by the listing in the First Section in 1985.

The company celebrated the 50th anniversary of the foundation in 1997, and will as a general construction firm specializing in the foundation works do its best to contribute widely to the society to be appearing in the 21st century.
