A new building is proposed with a deep basement (10 meters below ground level) to be placed on rock. Borings indicated glacial till (4 meters deep on average) over shale. The shale is of varying hardness, so a seismic refraction survey was done. The results showed the shale has a seismic velocity of less than 1 km/sec except for a 30 cm thick layer at 8 meters below the surface. The seismic velocity of that layers is 3.5 km/sec. Provide a couple of recommendations for dealing with this layer. (Note that the shale can support the building without any structural issues.)

Sediment transport

Sediment transport or Soil transport is the movement of solid particles, usually due to the combination of gravitational forces acting on the sediment, and the movement of the liquid at which the sediment enters. Soil erosion occurs in natural systems where the particles are sandstones (sand, rocks), mud, or clay; the liquid is air, water, or ice; and the gravitational force that works to move particles to the landing surface. Sediment transportation or soil migration due to the movement of liquids occurs in rivers, lakes, lakes, oceans, and other bodies of water as a result of currents and waves. Transportation is also caused by glaciers as they flow, and to places on earth under the influence of wind. Soil erosion due to gravity alone is possible in most sloping areas, including hills, scarves, cliffs, and the continental shelf — the continental boundary of the slope.
