Technical Information

Technical parameters

Technical approach

Investigation and consulting scope should be defined according to project stage, site conditions, structural requirements, and applicable standards.
Site investigation, geological interpretation, testing data, and engineering analysis are coordinated to support foundation, excavation, and underground engineering decisions.
Project-specific recommendations should be developed based on verified investigation data and design requirements.

Key control items

Investigation scope, data reliability, and testing quality.
Geological and hydrogeological condition interpretation.
Foundation, excavation, and underground engineering risks.
Interface coordination with design, construction, monitoring, and review requirements.
