What we model, design & verify

Numerical modelling is not an optional extra — it is risk management. We use PLAXIS 2D & 3D to simulate what the ground will actually do, across the full range of geotechnical challenges in GCC construction.

PLAXIS 3D foundation settlement model
01

PLAXIS 2D & 3D Numerical Modelling

Finite-element analysis of deformation, stability and safety — selecting the right tool for the problem, not for convenience.

02

Deep Excavation & Shoring Design

Secant pile walls, soldier piles with struts and anchored systems — designed and checked through the full construction sequence.

03

Soil–Structure Interaction

How excavations, new loads and adjacent construction affect existing structures — captured at every critical stage.

04

Pile & Pile-Raft Foundation Design

Individual pile modelling, load distribution and differential settlement — revealing corner vs. centre pile behaviour 2D can't.

05

Retaining Walls & Adjacent Impact

Lateral earth pressure, wall deflection and bending-moment envelopes when a new building or footing changes the picture.

06

Settlement & Consolidation

Time-dependent settlement and consolidation analysis to predict performance — uniform or differential — before construction.

07

Slope Stability Analysis

Factor-of-safety assessment and reinforcement design for embankments, cuts and sloping or layered ground.

08

Ground Improvement & Grouting

Sabkha, loose sand and problematic soils — grouting and ground-improvement schemes verified for settlement control.

09

Tunnels, Underpasses & Bridges

Underground structures, underpass excavation near piers and micropile interventions to protect bridge foundations.

Also available: geotechnical peer review & third-party design checks, modelled factor-of-safety verification (the modelled FoS, not the assumed one), and design-stage optimisation that costs a fraction of remediation later.
Capability · The Right Tool

2D is not wrong. It's
just not always enough.

Most geotechnical analysis in everyday practice is two-dimensional. But some problems cannot be solved in two dimensions — and knowing the difference is one of the more consequential judgement calls in geotechnical engineering.

2D vs 3D settlement behaviour comparison — PLAXIS
PLAXIS 2D

Fast, efficient, plane-strain

  • Ideal for straightforward, regular geometry
  • Simplifies a problem to a representative section
  • Quick everyday deformation & safety analysis
  • Cannot reflect corner vs. centre behaviour
PLAXIS 3D

Full soil volume & true behaviour

  • Each pile and footing modelled individually
  • Captures 3D load distribution & stress concentration
  • Reveals true settlement pattern across a raft
  • Essential for complex geometry & layered ground
For projects with complex geometry, loading or ground conditions — a significant share of the Kingdom's current construction cycle — choosing 2D because it's faster is a risk-management decision, not a technical one.
Selected Projects

Real ground. Real decisions.

A selection of geotechnical analyses delivered with PLAXIS 2D & 3D across the region. Each was the basis for a design decision — not an assumption, but a simulation of what the ground would actually do.

New Building Effect on Existing Shoring

About · Building Capability

Raising the standard of geotechnical practice

A geotechnical report tells you what the ground is made of. Numerical modelling shows you how the ground and structure behave together in real conditions — the difference between an assumed factor of safety and the one that actually governs your project.

Concept Dash brings certified, practice-led numerical modelling and training to engineering teams across the Kingdom and the broader GCC, led by a PhD-qualified geotechnical training provider with PLAXIS 2D & 3D delivery on live regional projects.

Sabkha-aware stratigraphy soil model

Stratified soil model — each layer assigned its own stiffness & strength parameters before any load is applied.
