Industries
Long-span roofs, trusses and public-infrastructure steelwork.
Quick answer
Structural Engineering Services supports Infrastructure & Stadia projects worldwide with long-span roof structures, structural design services, tekla 3d modeling, steel connection design — delivered by senior engineers on licensed software to international codes.
Governing codes
Sector challenges
Long-span and public structures are seen by everyone and inspected by everyone. The geometry is ambitious, the connections are on display, and the tolerances have to work on a site where nothing is square.
Challenge 01
Beyond about sixty metres the structure is governed by deflection, pre-camber and dynamic response, not by member strength.
How we answer it
Spans are checked for serviceability and footfall response, pre-camber is calculated and shown on the drawings, and erection-stage geometry is set so the finished shape is the designed one.
Challenge 02
Large roofs move with temperature and will crack whatever they are restrained against.
How we answer it
Movement joints and sliding or pinned bearings are designed with calculated travel, and the restraint system is set out so the structure expands where it is intended to.
Challenge 03
Architecturally exposed steelwork puts the connection on display and the tolerance under scrutiny.
How we answer it
AESS connections are designed with weld class, grinding and finish requirements noted on the drawing, and node geometry is resolved in the 3D model before steel is ordered.
Challenge 04
A long-span truss is at its most vulnerable half-built, sitting on temporary towers in the wind.
How we answer it
Erection stages are analysed with temporary supports, stability checks and a jack-down sequence, so the method statement is backed by calculation rather than experience alone.

ExploreTypical assets
From a single assembly to a complete package — the asset types our infrastructure & stadia teams work on week to week.
Cantilever roofs, compression rings and cable-supported or trussed arena structures.
Trusses, space frames and lattice shells for halls, hangars and terminals.
Terminal roofs, canopies, link bridges and concourse structures.
Pedestrian bridges and link walkways including vibration serviceability.
Feature canopies, porte-cocheres and tensile structure support steel.
Raker beams, terracing supports and stand framing under crowd dynamic loads.
Codes & specifications
The base code is only half the story. On infrastructure & stadia work the client specification usually overrides it somewhere, so we agree a single reconciled design basis before any calculation starts.

Deliverables & handover
Public-realm projects are handed over with the geometry control data — setting-out points, pre-camber and node coordinates — because the survey team on site needs numbers, not drawings.
