Temporary shoring work in Agoura Hills

At the Wallis Annenberg Wildlife Crossing, early bridge and abutment construction along US 101 needed earth support before the southerly grading was complete.

Cefali & Associates designed temporary shoring for general contractor C.A. Rasmussen. Malcolm Drilling installed the support at the base of the crossing site.

Local conditions

Support that followed the grading sequence

The design used available Caltrans beams and allowed height to be added to the top of the shoring as grading backfilled the slope toward abutment level.
