Structures designed
holistically.

From concept to completion through structural analysis and design, detailing, fabrication and installation.

Semantica Consulting delivers projects which are feasible and buildable — because we care.

01 · Our approach

“We don’t design in isolation. We design holistically: projects covering every design aspect, structural design, detailing, fabrication and installation.”

Holism is the old idea that the parts of a system only make sense in terms of the whole — and a structure is exactly that kind of system. An analysis model, a connection detail and an erection sequence are not separate jobs: each one only works when it serves the whole. Problems are rarely solved by the same narrow thinking that created them, so we widen the frame before we sharpen the numbers.

Thinking in wholes is also how we design sustainably: material-efficient forms, details a fabricator can make without waste, structures that can be erected safely and maintained honestly. Services-led, Semantica takes responsibility for the whole structural story — so fabricators can price it, contractors can build it, and owners can rely on it.

02 · How we design

One continuous line,
from idea to installed.

Our design cycle keeps safety at the centre, and every stage feeds its lessons back into Project Strategy. Hover or tap a node to see how.

PROJECT STRATEGY DESIGN DETAILING FABRICATION ERECTION SAFETY: ENHANCED SAFETY AND DE-RISKING

Safety: enhanced safety and de-risking

Enhanced safety and de-risking span every stage — design, detailing, fabrication and erection. We consider buildability, handling and installation early, with calculations presented clearly enough for rigorous independent checking.

Extended knowledge and experience in all aspects of structural engineering allow us to deliver high-performance services.

Structural inspection of an existing asset
Close the loop. Inspection informs assessment, detailing and the next intervention.

The cycle in practice — six stages, one responsibility

Concept

Choose the structural form before anyone falls in love with a shape. Load paths, spans, articulation and buildability are set here — so is most of the cost.

03 · What we do

Four industries.
Nine services.

Specialist structural input where it carries the most consequence — delivered with detailing, fabrication and installation in mind, never analysis alone.

Industry 01

Infrastructure & bridges

Design, assessment and independent assurance for bridges and the structures around them — grounded in first principles and road-tested judgement.

Industry 02

Construction & temporary works

Engineering for the stages between drawing and standing structure — temporary works and heavy lifting, steelwork and the connections that hold it all together.

Industry 03

Gas & energy

Structural and civil design and assurance for the gas industry, keeping schemes compliant and moving.

Industry 04

Industrial process plant

Plant-side structural design where process, pressure and dust meet steel.

Nine services.

01

Bridge design & assessment

New bridge design and assessment of existing assets. Analysis that establishes what a structure can carry, and advice on what should happen next.

  • New structures
  • Existing assets
  • Assessment
02

Special & engineering structures

Non-standard structures where geometry, loading or detailing sit outside routine building work — worked through from first principles.

  • Special structures
  • First principles
03

Inspection & structural assessment

Focused inspection and assessment that tells asset owners what condition really means — and where intervention is worth it.

  • Condition
  • Prioritisation
04

Independent design checks incl. Category III

Rigorous independent checks of structural designs — assumptions, analysis and details examined, findings reported so they can be closed out.

  • Category III
  • Independent review
05

Temporary works & lifting / erection engineering

Temporary works, lifting studies and erection engineering designed around the construction sequence — so the structure is stable at every stage, not just the last one. Semantica specialises in heavy lifting temporary works.

  • Developing sling arrangements.
  • Specifying shackles and lifting points.
  • Selecting proprietary lifters such as RUD VLBG load rings, or designing bespoke lifting lugs.
  • Temporary stability
  • Heavy lifting
  • Sequencing
06

Steel & concrete structures

Design and analysis of steel and concrete structures with careful material understanding and efficient, buildable detailing.

  • Steelwork
  • Reinforced concrete
07

Connection design for fabricators

Full connection design as a service to steelwork fabricators — moment, shear and splice connections designed, justified and drawn for the shop floor.

  • For fabricators
  • Moment & shear joints
  • Shop-ready
08

G17/G35 approver & appraisal services

Approver and appraisal services against G17 and G35 procedures for structural and civil works on gas infrastructure — independent review that unblocks schemes rather than stalling them.

  • IGEM G17
  • IGEM G35
  • Approval & appraisal
09

Dust explosion & filtration plant design

Hoppers, plenums and ducts — where most dust explosions actually happen — designed for deflagration from the outset. Filtration plant structures and their explosion resistance engineered together, not bolted on afterwards.

  • Dust hoppers
  • Plenums & ducts
  • Designed for deflagration

04 · Beyond analysis

We design for detailing, fabrication and erection — not just analysis.

A model that converges is not a structure that stands. Every Semantica design is carried through to the questions that decide whether site goes well:

  • Connections designed in, never left “by others”.
  • Details a fabricator can price — bolt access, weld positions, tolerances, transport splits.
  • An erection method that works — stability, lifting and sequence engineered before steel leaves the yard.
