Geotechnical Investigation

Rigorous site characterisation is the foundation of every sound engineering decision. We design and manage investigation programs scaled to the project — from desktop reviews and single test pits through multi-phase borehole and CPT campaigns.

Site characterisation and subsurface profiling
Borehole drilling programs and supervision
Cone penetration testing (CPT / CPTu)
In-situ testing: SPT, vane shear, pressuremeter
Laboratory testing programs and interpretation
Geotechnical investigation reports (GIR)

Excavation + Shoring

Deep excavations in urban BC require careful analysis and tight contractor coordination. We design temporary retention systems and provide the field oversight that keeps projects on schedule and adjacent structures safe.

Sheet pile and soldier pile wall design
Tieback anchor design and proof-test review
Braced and cantilevered excavation support
Dewatering assessment and design
Contractor technical support and RFI response
Settlement monitoring of adjacent structures

Ground Improvement

Challenging subsoils don't always require deep foundations. We evaluate ground improvement options to reduce cost, minimise settlement, and make difficult sites buildable — matched to your schedule and budget.

Compaction specifications and verification programs
Dynamic compaction and vibro-compaction review
Preloading and surcharge design
Prefabricated vertical drain (PVD) systems
Settlement monitoring and back-analysis
Grouting specification and QA review

Foundation Design

We translate subsurface data into foundation systems that meet your structural loads at the lowest lifecycle cost. Every recommendation is calibrated to actual site conditions — not a generic template.

Spread footings and combined footing systems
Driven and drilled pile foundations
Grade beams and strip footing design
Mat and raft foundations for soft-ground sites
Pile load testing review and interpretation
Construction-phase technical review

Retaining Walls

From small residential tiered gardens to large infrastructure embankment walls, we design retaining systems that are stable, constructible, and cost-appropriate for the site and loading conditions.

Gravity and semi-gravity wall design
Cantilevered reinforced concrete walls
Anchored and deadman wall systems
Mechanically stabilised earth (MSE) design
Drainage and surcharge recommendations
Construction review and sign-off

Slope Stability

BC's terrain demands rigorous slope hazard analysis. We assess risk, model failure mechanisms, and design remediation strategies that are practical to implement — for a single infill lot or a linear infrastructure corridor.
