Temporary shoring design in Santa Monica

Discuss your project

The March 31, 2025 administrative-approval plans for 2919 and 2923 Wilshire Boulevard in Santa Monica identify Cefali & Associates as shoring engineer. The proposed mixed-use development includes 127 residential units and four subterranean parking levels.

The published drawings establish a design-stage shoring appointment and are marked preliminary and not for construction. Excavation support needs to be developed with the planned basement and the permanent building design.

Site conditions

Excavation support during below-grade design

Basement geometry and construction stages

Below-grade parking requires support while excavation and foundation construction progress. Shoring design uses excavation plans, geotechnical criteria, equipment access, and the planned sequence to establish support for the stages before the permanent structure is complete.

A distinct shoring appointment

Cover sheet G000 lists Cefali as shoring engineer and identifies separate building structural and geotechnical engineers. The shoring layout needs to work with the permanent building geometry and the ground criteria supplied for the site.

From preliminary plans to support design

Early drawings can establish the proposed basement arrangement and the space available for construction. Detailed shoring design then depends on the project-specific depths, loads, nearby structures, utilities, and access information developed by the team.

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.
