Rapid investigation and analysis of residual soil acceptance criteria to avoid construction stoppage.

Delays in construction projects can lead to significant losses. This survey service provides the necessary pre-compliance analysis for the disposal of excavated soil at an overwhelming speed, thoroughly avoiding work stoppages. It instantly clears the complex regulatory standards that vary by region and municipality, and quickly navigates to the selection of optimal disposal sites. It also responds without setbacks to strict specifications based on volume, such as 5000m3 in Chiba Prefecture and 2500m3 at Tokyo Port. By selecting the most suitable sampling methods based on the situation and implementing an efficient process that eliminates waste, we achieve significant reductions in analysis costs and shortened delivery times. Geotech's reliable speed response strongly supports sites with tight construction schedules.
