Shoring and excavation support

Earth shoring engineering in San Bernardino

Discuss your project

A redevelopment excavation in San Bernardino may have to retain ground beside an existing building while leaving a route for excavation equipment. Cefali & Associates designs earth shoring for basements, foundation cuts, and retaining work around those constraints.

Our California experience includes cross-lot bracing above truck traffic at Intuit Dome in Inglewood and soil nail walls with soldier pile transitions at Vista Monterey in Corona. Each illustrates a different limit on where support can fit.

Excavation and construction

Redevelopment beside existing infrastructure

San Bernardino’s Downtown Specific Plan materials address land use, mobility, and infrastructure together. For a building project in an established block, existing utility lines, neighboring foundations, and public frontage can restrict both the cut and the reach of its support.

Soldier piles can retain a vertical edge while tiebacks or braces carry lateral loads. Anchor paths need available ground and appropriate rights. If support must stay inside the excavation, brace elevations and foundations need to fit around the proposed building work. The city planning context does not establish a particular soil profile or shoring system.

Excavation and construction

The ramp and the bracing share the excavation

An internal support layout can obstruct the same route needed to remove soil or bring in concrete. Ramps and equipment also apply loads while the excavation is open. Structural shoring design needs those temporary positions and stages, not only the final basement dimensions.

At Intuit Dome in Inglewood, Cefali positioned entrance-tunnel cross-lot braces above the truck route where tieback agreements were unavailable. For a San Bernardino site, the proposed access and permanent foundations determine whether a similar type of arrangement is feasible. The contractor develops the installation and operating methods.

Engineering scope

From a support concept to structural details.

A concept for bidding, detailed drawings and calculations, and engineering for construction-stage changes can be separate assignments. The proposal identifies the services included. Geotechnical assessment, water-control design, property rights, and contractor installation remain distinct responsibilities.
