Geocon Consulting on Hawaiian Island Development

The approximately 1000-acre Kukuiula resort community is located on the beautiful south shore of Kauai. This exclusive development is positioned on gently sloping volcanic terrain with spectacular panoramic views of the Pacific Ocean. The up-scale community boasts a variety of amenities including a plantation club house, spa, parks and an 18-hole Tom Weiskopf-designed golf course commanding lofty views of blue sea and rugged volcanic coastline intermixed with lush plantation landscaping. Up to 1500 custom and cottage homes are approved to be constructed over the next 5 to 10 years with lot sizes up to 1.5 acres. The minimum price of a single-family cottage home is in excess of 2 million dollars. Significant Infrastructure consisting of a waste water treatment plant, three water reservoirs and a deep well system which will provide water for the project has been constructed and site grading is currently on-going. Since the project site is underlain be hard volcanic rock and expansive clays near the ground surface, important geotechnical considerations were required during grading with respect to rippability and materials management. Shallow blasting, the treatment of blast affected bedrock, oversize rock handling and placement, and grading with expansive soils were all significant challenges during project development. Geocon performed periodic third party geotechnical consultation and oversight during the grading of Kukuiula Phase I. Our role consisted of providing technical support to the engineer of record and assisting with the development of rock over-excavation criteria, and rock fill and expansive soil placement guidelines. These considerations were necessary to provide suitable building sites for the guest builders. Our services also included consulting with respect to geotechnical explorations in future phases of development.
