There is a large weight of effect from natural environment to our work field
By drawing our past experience and our basic principle we operate personnel, equipment, materials to meet the customer’s request.
We provide support to port facility used as a bridgehead of the logistic, shore line protection facility such as head land and island mole, maintenance and management of the navigation aids, and wave observing apparatus and telecommunication cable facility and more.

"A river, the wetlands" coherent to life are utilized widely as a waterway and a fishing ground and an oasis. I perform dredging work to maintain a waterway, a fishway and the mooring place of various ships used for the home of the fish and the place of the natural gathering place for fish structure that it is, the aquatic plant revival and people of peace and Shinsui Koen, fishery, traffic, the leisure when it is and the construction of a pier and the quality of the water purification facilities where it is that the fish goes.
I have a big influence on the life of people as a menace of nature without a flood and a disaster caused by the erosion cutting off the back in "the river" occurring frequently of the disaster when we have large rain once. We cope with urgent construction such as flood measures or the disaster restoration and repeat the results including the construction of observation equipment and facilities performing the maintenance of the river premeditatedly.

Bridge construction
| The lower bridge, the upper bridge, bridge floor version, seismic strengthening, temporary pier, old bridge removal |
It becomes the base of the traffic, and, also, a new establishment and the repair of a lower part mechanic equal to the supporting beam region of "the bridge" coherent to the life of local people and the upper part mechanic equal to the bridge road region support improvement, the maintenance construction to bridges to be able to go along in peace such as seismic strengthening construction to review the influence caused by the earthquake.
In late years, for a use change and deterioration, the dismantling removal construction of the old bridge rebuilt in Shimbashi increases the results as one of our main construction.

Diving construction
| I weld it in the water and fusion-cut it and level underwater concrete, the underwater digging, sacrifice and install observation devices |
By the underwater work, a diving person must perform all types of job whereas the worker of a great number of people is shared with the land work according to the type of job and undertakes construction, and the role and responsibility become important. Therefore, special qualification and experience in the water are necessary. We always consider safer work let alone aiming at the improvement of a diving technology, the skill.
