Cornerstone’s Value Added Benefits:

  • Cornerstone performed a phased investigation during preliminary planning and due diligence to reduce initial design costs. Once the project was approved, Cornerstone performed a design-level investigation to supplement our previous work.
  • Cornerstone presented cost-effective field solutions during construction to address construction challenges, including using lime-treatment to mitigate unstable pavement and building pad subgrade caused by winter rains, as well collecting unanticipated water seepage from adjacent properties.
  • Cornerstone recommended the use of geotextile stabilization fabric or geogrid to mitigate soft soils encountered in public sidewalk and street areas to reduce over-excavation and off-haul costs.
