Excavation support
Earth Retention Systems
Cefali & Associates designs earth retention systems for deep excavations and constrained sites where constructability matters.
- Soldier piles, tiebacks, soil nails, and internal bracing
- Temporary and permanent shoring applications
Excavation support
Temporary Shoring Design
Temporary shoring systems are developed around the realities of excavation sequencing, adjacent improvements, and contractor access.
- Bid-phase concepts through construction drawings
- Tieback, raker, cantilever, and braced excavation systems
Excavation support
Soldier Pile Shoring
Soldier pile systems remain a core excavation-support approach for many urban, mixed-use, and infrastructure projects.
- Cantilever and tieback-braced soldier pile walls
- Internal raker and cross-lot bracing coordination
Excavation support
Tieback Shoring
Tieback systems are selected and coordinated where they offer efficient excavation support without compromising nearby constraints.
- Tieback-braced excavation support
- Coordination near transit structures and neighboring properties
Foundation and stabilization
Soil Nail Walls
Soil nail walls can support stabilization and excavation needs where geometry, access, and sequencing require a targeted approach.
- Soil nail wall concepts and construction drawings
- Slope and retaining conditions
Foundation and stabilization
Micropiles
Micropiles can help resolve foundation support challenges where access, loads, or existing conditions limit conventional approaches.
- Specialty foundation engineering
- Foundation upgrades and existing construction support
Foundation and stabilization
Underpinning
Underpinning requires practical coordination around existing structures, excavation limits, and construction access.
- Existing building and foundation support
- Coordination with excavation support systems
Foundation and stabilization
Slope Stabilization
Cefali & Associates supports specialty stabilization projects where hillside, landslide, or retaining conditions require focused engineering.
- Hillside and landslide remediation support
- Soil nails, specialty foundations, and retaining systems
Review and coordination
Retaining Walls
Permanent retaining systems are developed with attention to structural performance, detailing, and adjacent site constraints.
- Permanent earth support systems
- Coordination with shoring and foundation systems
Review and coordination
Structural Peer Review
Cefali & Associates provides structural design review and technical input when projects need experienced engineering judgment.
- Peer reviews and expert witness support
- CAD, BIM, Revit, Navisworks, and computer modeling coordination
