Complex engineering solutions from concept to construction and fabrication drawings.
Structural analysis, optimisation and detailed 3D processing of industrial, technological, public and bespoke structures.
We treat a structure not as a series of separate elements, but as a single system.
The structural system, the connections, the foundation, fabrication and erection are coordinated
from the very start of the design.
Our goal is a structure that is safe and economical, can be fabricated and erected, and fits the
technological and architectural requirements — design is not merely calculation, but complete
engineering thinking.

Point-cloud site survey
A reliable structural model starts from the real, existing condition. For existing structures we can, where
needed, produce a detailed point cloud by laser scanning, LiDAR or photogrammetry — then fit the analytical
and fabrication model onto it (scan-to-BIM).
Textured point cloud of an existing industrial space — real “as-built” geometry
The survey captures the actual geometry of the existing structure — wall planes, openings, building services, connecting elements and deformations together. Design is then based on measured reality, not assumptions.
On-site scanning, LiDAR or photogrammetry on demand (point cloud)
Analytical and fabrication model fitted to the point cloud
Clash detection between existing and new structures
Early detection of dimensional deviations and deformations
Minimised fabrication risk from survey errors
Rich detail
Every detail from site
Real positions of openings, pipe penetrations and connections — with no detail left out.
Scan-to-BIM
Model on the point cloud
We fit the structural model onto the measured point cloud, designing precisely to the real environment.
Collaboration
Mark-up and coordination
We mark changes directly on the model, speeding up coordination with the contractor and the client.
From the model to a fabrication-ready package
The global structural model, connection checking, BIM coordination and the construction/fabrication documentation
are all part of one process. The goal is not to produce separate drawings, but a design package that is calculable,
verifiable, manufacturable and clearly erectable on site.

Design and construction support of cladding-support systems
Behind the visible cladding there is always a structural system at work: sub-frame, bracket, fixing,
thermal movement joint, load transfer to the substrate and a buildable connection. We do not treat these
as templates, but tailor them to the building geometry, the cladding material and the erection sequence.

Cladding sub-frames
Structure behind stone, porcelain, aluminium composite and bespoke cladding
For stone cladding, porcelain panels, aluminium composite panels (e.g. Alucobond), sheet-metal
cladding, louvres and the special claddings of transport spaces, the fixing, the back-up structure
and the movement joints are at least as important as the visible surface itself.

Transport spaces
Metro claddings

Metro claddings
Structural background of metro-station and tunnel claddings
In transport spaces the cladding-support system is not only an aesthetic question: vibration,
maintainability, fire-protection and operational requirements, the tight erection tolerances,
and the curved or articulated tunnel geometry together determine the solution.

Curved surfaces, bespoke panel layouts and concealed sub-frames
Operational access, demountability, maintenance and erection sequence considered
Support for detail drawings, sections, connections and contractor coordination
Road & railway structures
In a transport environment a structure does not stand alone: dynamic effects, operational constraints,
maintainability, buildability and a precise connection to the existing infrastructure all have to be
taken into account.
Transport structures
Signal gantries, maintenance walkways, bridge-like steel frames and related detail structures
For railway and road facilities the design ranges from global load-bearing capacity to bolted and welded
connections. The goal is a safe, manufacturable, erectable and long-term sustainable structural solution.

Why S-CAD?
One integrated structural view
We handle the global behaviour, the details, the connections and buildability together.
Manufacturable & erectable solutions
Beyond analytical compliance, we also consider fabrication operations, transport and on-site erection.
Detailed 3D processing
The models are the basis of coordination, checking, fabrication and change tracking.
Engineering support through to delivery
Where needed, we also take part in fabricator, contractor and on-site coordination.
Does the foundation task also require geotechnical analysis?
Where needed, we handle structural and geotechnical design tasks in a coordinated way.
