HAI conducted a geotechnical investigation to provide foundation and grading recommendations for eleven (11) multi-family apartment buildings.

The second phase of the project included providing Construction Quality Assurance (CQA) and laboratory and in-situ testing services during grading operations. This phase also included recording ground vibrations generated by the grading equipment near the City of La Verne Pump Station, adjacent to the project working area, to ensure safe operation of the pump and piping equipment. Additionally, the effect of vibrations on the integrity of concrete walls of a flood control channel along the site property line was investigated.
