Ensuring the highest standards of structural quality with safety as the top priority.

Ensuring the highest standards of structural quality with safety as the top priority.

Drawing on the specialized and advanced expertise developed through years of involvement in cutting-edge large-scale construction works—including large-diameter shield tunneling, deep excavation works, and complex bridge projects—as well as maintenance works addressing structural damage, seismic disaster prevention, and environmental measures, and facility engineering involving architectural, electrical and communications, and mechanical systems, we have established a support framework to ensure the highest quality and safety standards even under the most demanding constraints.

Construction Management Services

We provide comprehensive construction management services throughout all phases of a project, including the review of construction plans and related documentation, on-site witness inspections, safety inspections and guidance, and progress monitoring to ensure safe and high-quality project delivery.

Construction Management for Construction Works

For construction works, we apply the knowledge and latest insights developed through girder erection under constrained conditions to provide support for construction management.

Construction Management for Maintenance Works

For maintenance and repair works and large-scale renewal works on existing structures affected by aging or damage, we thoroughly assess the condition of existing structures based on construction-era records and inspection data, and carry out review of construction plans and verification of construction status. In all cases, safe and reliable construction with due consideration for the surrounding road environment is required, and we apply expertise developed under constrained conditions to provide construction management support.

Construction Management for Facility Engineering

We provide construction management support for a wide range of facility engineering, including new construction and maintenance works for architectural facilities such as ventilation stations, toll plazas, and parking areas; electrical facilities such as road lighting, traffic control communication equipment, and power receiving and transforming equipment; and mechanical facilities such as tunnel ventilation systems and disaster prevention equipment.
