Services We Provide

Geotechnical Engineering

Geotechnical engineering incorporates the evaluation of earth materials and development of design parameters of soils for design of civil structures.  Haro, Kasunich & Associates (HKA) staff has completed projects for both private and public clients, including landslide repairs, hillside improvement modifications, residential subdivisions, commercial buildings, parks, schools, hospitals and public infrastructure (including major bridges) projects.  Our services include the following:

COASTAL ENGINEERING

Coastal engineering services, combined with geotechnical engineering services, are an extension of the evaluation of earth materials influenced by the coastal processes.  Both are used for development of engineering of soils and rock for design of coastal protection and/or civil structures.  HKA here too have completed numerous coastal engineering projects for both public and private clients, including residences, commercial and public projects within the coastal influence.  Our services include the following:

  • Coastal Protection Facilities

  • Sea Walls

  • Wharf pier structures

  • Coastal Erosion Process Studies

  • Bluff Stability Studies

  • Coastal foundations

  • Coastal walls

  • Waterfront structures

  • Wave runup analysis

  • Sea wall and revetment inspections

Earthwork Construction Testing and support

Geotechnical engineering services continue into the earthwork construction phase as Earthwork and Observation and Testing.  Backed by our engineering staff, our technicians observe and test earthwork construction, document the contractor’s compliance with the project plans and specifications and provide constructive participation with the construction team to correct deficiencies while not directing the contractors operations.  Specification functions of the HKA’s staff include:
