Engineering-geological surveys

Engineering-geological surveys constitute an essential set of field, laboratory, and analytical investigations aimed at studying the physical-mechanical properties and lithological structure of soil at the site of future construction.

A set of works to study the properties and structure of the soil at the site of future construction enables engineers to determine optimal foundation types, calculate bearing capacities, and prevent differential structural settlement.

Across Tashkent, the Tashkent Region, and throughout Uzbekistan, the licensed geological company Tashkent — GEO PRO executes certified engineering geological surveys for construction Tashkent with guaranteed state expertise clearance.

Regional soil conditions (collapsible loess soils of types I and II, soft silts, alluvial gravels, running sands, and high groundwater tables) necessitate detailed seismic microzonation and soil liquefaction assessments.

Comprehensive geological surveys Uzbekistan and advanced engineering-geological surveys allow design institutes to optimize foundation dimensions and safeguard long-term structural integrity.

When Geological Surveys for Construction are Required

In accordance with the Urban Planning Code of the Republic of Uzbekistan and statutory ShNK / KMK building regulations, accredited engineering-geological surveys are mandatory during the pre-design stage:

• Design and erection of multi-storey residential complexes, high-rise office towers, and mixed-use commercial centers;
• Construction of heavy industrial facilities, manufacturing workshops, logistics parks, and warehouse terminals;
• Laying linear infrastructure: trunk pipelines, highways, railways, bridges, overpasses, and high-voltage transmission lines;
• Structural reconstruction, foundation underpinning, and vertical building additions with increased design loads;
• Site development across complex terrain and active geohazard zones (slopes, ravines, floodplains, and landslide areas);
• Assessment of geotechnical impacts caused by deep foundation excavations on adjacent urban developments.
