Geotechnical design is an important element in the preliminary stage of all structures, and Mannvit’s specialists have vast experience in this field. The most extensive projects are in connection with power plant projects, steel pilings in harbor construction, dam design, infrastructure and power intensive industries.
Mannvit’s consultants have extensive experience in geotechnical design and the supervision of such structures. They evaluate structural tolerances, calculate stability, make settlement predictions and assess the danger of liquefaction during earthquakes. In larger projects, there is often the need to conduct comprehensive and specialized geotechnical research on bedrock and the characteristics of loose strata.
Research is conducted on minerals intended for use, and on foundations for structures. Where rock is at depth, SPT and/or CPT-holes are drilled to determine soil characteristics. In addition, undisturbed samples are taken to evaluate shear strength and settlement properties.
Larger buildings are typically founded on piles if solid ground is deep below the surface, but with lighter structures it is possible to place a surcharge load (pre-loading) on the construction site to obtain the projected settlement that the building would otherwise cause.
