The Leighton Solution.

Leighton provided geotechnical and material testing services in conformance with the construction documents and the City of La Quinta’s Quality Assurance Plan (QAP).

The project required the identification suitable onsite soils for bridge abutment and constructing cement treated steep slopes for the channel side slopes.
Our services included soils and concrete testing during fill placement for bridge approaches, concrete box girders, curb and gutter, sidewalks, paving, and associated appurtenances.

Material testing services were in compliance with applicable Caltrans and federal requirements.
