Open service pageProof: Wilshire Grand Center, Intuit Dome
Specialty structural engineering
Engineering below-grade risk into buildable design.
Cefali & Associates helps developers, owners, architects, and construction teams solve complex excavation, shoring, earth retention, and specialty foundation challenges before they become schedule or cost problems.
Capabilities
Engineering support for the expensive parts of difficult sites.
Focused structural engineering for earth retention systems, temporary shoring, specialty foundations, and construction-phase coordination when the excavation or foundation is carrying real project risk.

Process
From site risk to buildable drawings.
Five coordinated stages keep the engineering tied to access, sequencing, and field reality.
Site riskSystem designField support
Triage
Review the site condition, adjacent structures, access, and likely excavation or foundation risk.
Inputs
Study plans, geotechnical reports, existing drawings, photos, and project constraints.
System
Select practical shoring, retention, underpinning, or specialty foundation approaches.
Sequence
Coordinate drawings and calculations around contractor access, staging, and field constraints.
Support
Stay available for construction-phase questions, revisions, and coordination.
Markets
Portfolio breadth without losing the specialty focus.
Private Development
Private development work often requires excavation support, specialty foundations, and coordination around dense urban conditions.
