For the new construction of warehouses for various logistics companies in the Hamburg area, investigations of the building ground with foundation assessment as well as inspections of the contaminated site situation with regard to possible additional disposal costs due to contaminated soils are necessary.

As a rule, the sites are already developed with commercial properties, so that the plans include the demolition of the existing building and the construction of a new logistics property.

General scope of services in the field of subsoil / geotechnics:

• Small pile-driving holes (KRB) into the natural soil,
• Heavy dynamic probing (DPH) at least into the natural soil to determine the bearing density or
• Pressure soundings (CPT) to determine the bearing density of cohesive soft layers in the subsoil,
• Expansion of small pile-driven boreholes into temporary groundwater measuring points and groundwater sampling to estimate the aggressiveness of the concrete and steel as well as possible groundwater contamination,
• Taking of soil samples for soil mechanical laboratory testing (determination of soil parameters such as water content, grain size, consistency determination and determination of the structural suitability of the soil and determination of infiltration capacity),
• Taking of soil samples in the area of fillings to determine the general soil condition in relation to possible contamination, investigation according to LAGA TR Boden 2004,
• Measurement of the survey points according to position and height,
• Evaluation (technical and economic) of the foundation types/depths,
• Forecast of the settlements to be expected in the construction area,
• Presentation and evaluation of the investigation results in a geotechnical report.
