Multi-beam bathymetric survey utilized for the maintenance and management of harbors, fishing ports, and dams.
In-house owned multi-beam sonar (for waterway infrastructure)
Enhancing the maintenance and management of water infrastructure using three-dimensional terrain data! Supporting sediment accumulation monitoring and long-term change comparison.
In waterway infrastructure such as ports, fishing ports, and dams, regular topographical surveys are required for long-term maintenance management. Localized sedimentation and erosion conditions that cannot be captured by conventional single-line surveys can be visualized in a planar manner through multi-beam sonar. Our company utilizes its own multi-beam sonar equipment to acquire three-dimensional data of the seabed topography. We conduct analyses that can be used for maintenance management tasks, such as comparing changes over time and estimating sediment volumes. 【Main Services Offered】 - Confirmation of changes over time through regular depth surveys - Monitoring of sedimentation progress - Acquisition of current topography for dredging plan considerations - Preparation of foundational data for maintenance management planning - Verification of seabed topography around structures We propose the development of data that serves as decision-making material for maintenance management, going beyond mere surveying.

Company information
Since its establishment in 1966, East Japan Construction Consultant has been proposing "aha!" moments centered around surveying and design technology for many years. Starting with surveying and expanding into design, land acquisition, compensation, and infrastructure maintenance, we have worked as a comprehensive construction consultant to enhance our services. We have been engaged in the development and maintenance of social infrastructure that supports people's safety, security, and economic activities, including roads, rivers, ports, marine surveys, urban planning, and energy. Currently, in addition to our efforts in disaster prevention, mitigation, and national resilience, we are also focusing on digital transformation (DX) through initiatives such as BIM/CIM, AI, UAVs, and ROVs (underwater drones).
