Ocean View Elementary

 

Key Features 

 

  • Five new 1 & 2-story classroom and administrative buildings, along with new play areas to upgrade to current CBC codes and standards

  • Demolition and removal of existing buildings and structures 

 

Geotechnical Challenges

 

  • Localized areas of liquefiable soils and loose soils

  • 6 to 13 feet of undocumented expansive clay fill at surface of site

  • Shallow groundwater table

  • Unforeseen existing foundation elements and demolitions

  • Variable alluvium layer underlying upper layer of fill

 

Innovative Solutions

 

  • Provided refined analysis and mapping of localized liquefiable soil layers.

  • Collaborated with structural engineer to develop economical shallow foundations capable of withstanding differential settlement potential

  • Monitored existing foundation demolitions and recommended expedient mass-excavation and backfill of affected areas

  • Provided cost and time savings of earthwork and grading from on-site assessment regarding the variable alluvial soils being reused as non-expansive and engineered fills
