Concrete structural verification
Independent verification and design review of concrete structures
We support national and international clients, contractors and engineering consultancies with technical reviews, second opinions and independent verification of existing and new reinforced-concrete structures within civil infrastructure.
Service
Focused review of reinforced concrete calculations
We review structural calculations, design assumptions, SCIA and other FEM models, reinforcement and detailing. This enables independent design and calculation reviews for bridges, viaducts, tunnels, underpasses, quay walls and other civil engineering structures.
The review approach combines structural engineering depth with practical project experience. We assess not only technical compliance, but also safety, buildability, durability and execution feasibility within the project context.
Registered Structural Engineer level
The expertise is delivered at Dutch Registered Structural Engineer level, comparable to incorporated or chartered structural engineering responsibility depending on the project context. We are used to hybrid working, international project teams and coordination between design, construction and multiple disciplines.
Scope
What can be reviewed
Loads and load combinations
Structural schematisation
Hand calculations and calculation reports
SCIA and other FEM calculation models
ULS and SLS checks
Bending, axial force, shear and torsion
Crack width and deformation checks
Fatigue, where applicable
Reinforcement and structural detailing
Anchorage, lap lengths and force transfer
Constructability and execution feasibility
Reassessment of existing civil engineering structures
Processing and answering review comments
Outcome
What the client receives
The exact outputs are agreed upfront based on the verification scope, contractual requirements and available project information. This keeps the review focused, traceable and useful for project decision-making.
Carefully scoped
For formal verification processes, we agree the required independence, verification class, qualifications and project-specific acceptance criteria with the client in advance.
Agreed verification scope
Assessment of assumptions and design documents
Review of calculations and calculation models
Structured comments or verification matrix
Classification of comments by technical relevance or risk
Check of comment processing and responses
Technical coordination with designers and the project team
Final verification note, review report or second opinion, depending on the agreed scope
Approach
From scope to verification product
- Technical intake and definition of the scope
- Receipt and inventory of documents and models
- Assessment of assumptions, calculations and detailing
- Recording and discussing review comments
- Checking revisions and responses
- Completion with the agreed verification product

No generic certification claim
The applicable standards, employer's requirements and project-specific frameworks are defined in advance. No generic certification claim is made unless it is explicitly part of the assignment or project acceptance process.
Independence
Clear agreements before the review starts
Technical review of calculations, models and design assumptions
Second opinion on a design choice, detail or verification result
Independent review outside the original design team
Formal contractually required verification, after alignment on requirements and acceptance criteria
