Outlines by business

Construction work to eliminate utility poles

We contribute to disaster resilient urban development through the introduction of social infrastructure such as common cable ducts for communications and electrical cabling to eliminate aboveground utility poles. In addition to proficiency with telecommunications equipment, we leverage our many years of experience, proven track record and knowledge to provide proposals and carry out construction work to eliminate utility poles.

Installation, replacement or renewal of underground utilities with Trenchless Techniques

Using underground excavation technologies developed over many years, we contribute to the improvement of lifeline facilities such as water supply and sewerage systems. Even for locations where roadway excavation is not possible, we build pipes and drains while developing proposals to significantly reduce environmental impact such as noise, vibrations and traffic restrictions.

Maintenance work on underground facilities

We apply special construction techniques to existing underground structures and other aging facilities, upgrading them into sound structures and contributing to updated social infrastructure. Specific activities include everything from tunnel repair and reinforcement work to small work on manholes and other equipment. The use of W-RCS and other construction techniques shortens work times and provides eco-friendly construction.
