[Case 6] Water quality monitoring of nearby commercial wells associated with foundation pile construction (Fiscal Year 2009)
As experts in soil and water, we comprehensively support groundwater quality monitoring.
When the construction of a structure's foundation reaches an aquifer, there are concerns about the impact on the water quality of nearby wells that draw from that aquifer. This is especially critical for commercial wells, which require delicate management and emergency response measures. Central Development Co., Ltd., as an expert in "soil" and "water," provides comprehensive support for groundwater quality monitoring, including real-time monitoring services, planning of observation well placements, setting management standards, and developing emergency response manuals.

basic information
【Features】 ○ Installation of observation holes → Arrange primary, secondary, and tertiary holes in order of proximity to the construction site, and install turbidity meters. ○ Alarm criteria (stages for alarm email transmission) → Three stages: "Normal," "Caution," and "Alert." → The most stringent standard is set for the tertiary hole. ○ Data sampling interval → 5-minute intervals during "Normal" conditions, and 1-minute intervals during "Caution" and "Alert" conditions. → The data sampling interval can be changed remotely. ○ Emergency response (when reaching the Alert level) → When the pile reaches the confined aquifer, the tertiary hole reaches "Alert" level, and construction is temporarily halted. → After confirming that values have returned to normal, construction resumes. → To maintain water quality upon resuming construction, the excavation speed was reduced from the initial rate. ● For more details, please contact us or refer to the catalog.

Company information
Our company was founded in 1946, shortly after the end of the war, at a time when Japan's post-war reconstruction required an increase in food production and energy development. It was established with a group of engineers possessing the necessary development technologies at its core. Since then, we have contributed to civil engineering projects, focusing on roads, rivers, and dams, as well as the development and enhancement of various public facilities and industrial infrastructure, utilizing our expertise in geological surveys, ground analysis, and civil planning and design. Today, we have gained trust from various ordering organizations and have had the opportunity to demonstrate our capabilities, expanding our operations both nationwide and overseas. Starting this fiscal year, we are pursuing the CKC Sustainable Growth Vision, aiming to become a "one and only company that contributes to the formation of a safe and secure national land and the development of a sustainable future society."
