Early bridge construction
The shoring supported construction at the base of the crossing site before the southerly earthwork had reached its later grade.
Bridge and abutment work at the Wallis Annenberg Wildlife Crossing started before the southerly earthwork was complete. Temporary shoring held the ground at the base of the site while that early construction proceeded.
Cefali & Associates designed the support for general contractor C.A. Rasmussen, and Malcolm Drilling installed it. The shoring height could be increased as grading backfilled the slope toward the abutment.
Site conditions
Earth support during staged grading
Support height changed with backfill
The design used available Caltrans beams and allowed additional height at the top of the shoring as the slope was backfilled.

Engineering scope
From local project to your site
These projects show how excavation depth, neighboring structures, access, and the permanent work can change the support design. Your site needs its own geotechnical criteria and structural design. The contractor determines installation and construction means and methods.
