All forms of development (e.g., residential, commercial, industrial, public infrastructure, etc.) typically involve some level of earthworks (i.e., excavation/fill) to construct the necessary design elements and/or achieve the desired grade. The means by which earthworks are conducted at a given site are driven by many factors including (but not limited to):
The primary
concerns associated with earthworks generally center around constructing a
subbase that will support the overlying improvements with minimal risk of
settlements and/or differential movements within the subbase and underlying
native soils. Proper earthworks are
essential in subarctic and arctic climates, as they help to reduce the impact
that frozen soils (i.e., seasonal ground frost or permafrost) may have on
overlying improvements. Furthermore,
Alaska’s varied topography, along with its location within a seismically active
region of the world, increase the necessity for geotechnical assessment during
the design phase and proper earthworks during construction to help reduce the
impact that any subgrade failures may have on the proposed improvements.
