Construction ground investigations

An understanding of the ground conditions is the foundation for safe, cost-effective and sustainable construction projects. DMT carries out ground condition assessments, soil surveys and geotechnical investigations for buildings, infrastructure projects, industrial projects and complex civil engineering structures.

Our experts analyse the subsoil, assess geological and geotechnical conditions and identify potential risks at an early stage. The results provide the basis for decision-making regarding planning, planning permission, tendering and construction.

A ground investigation report assesses the geological, hydrological and geotechnical properties of the subsoil. It provides important information on the bearing capacity and deformation behaviour of the soil, groundwater conditions and potential risks to a construction project.

Site investigation reports assist in the selection of suitable foundation and construction methods and make a significant contribution to ensuring certainty regarding timings, costs and planning.

The characteristics of the subsoil influence virtually every construction project. Soil composition, bearing capacity, groundwater conditions and backfill all have a direct impact on planning, execution and long-term structural stability.

As part of our ground investigations, we record the relevant ground conditions through geotechnical field and laboratory tests, as well as digital analysis methods. The results are clearly documented and assessed in the ground investigation report.

This ensures that relevant constraints are identified at an early stage and can be specifically incorporated into planning and decision-making processes.

Geotechnical issues arise throughout the entire life cycle of construction and infrastructure projects. DMT supports clients from the feasibility study through to planning, construction and final acceptance.

By combining geotechnical engineering, surveying, digitalisation, data management and project management, we lay a solid foundation for efficient and transparent project delivery.

Construction work may have an impact on adjacent buildings, transport routes or civil engineering structures. Proper preservation of evidence documents conditions before, during and after the construction work and provides an objective basis for substantiating claims.

Site investigations for mining and former mining sites: Construction projects on sites affected by mining require specialist geotechnical expertise. Underground voids, shafts, backfilled areas and historic mining structures can affect the stability and usability of sites.

DMT combines more than 280 years’ experience in mining with modern geotechnical engineering and digital investigation methods. As part of the TÜV NORD GROUP, we develop assessment and safety concepts for challenging sites in Germany, Europe and worldwide.
