Telecom Structures.
Structural engineering for masts, lattice towers
and telecommunications structures.
Towers that stand
under any load.
Telecom structures and telecommunication masts are among the most structurally demanding free-standing steel structures in civil engineering — slender, tall, and exposed to dynamic wind forces around the clock.
IGG provides complete structural engineering for lattice towers, monopoles, guyed masts and rooftop antenna structures. Our designs comply with EN 1993-3-1 and EN 1991-1-4 (wind actions), and are validated through full 3D finite element analysis. We coordinate directly with telecom operators, tower owners and civil contractors to deliver documentation ready for permitting and construction.

The structural challenge of towers.
Wind Dominates Everything
For tall slender structures, wind is the governing load — not gravity. We perform detailed wind pressure distribution analysis per EN 1991-1-4, accounting for terrain category, orography, turbulence intensity and the drag contributions of attached antennas and cables.
Dynamic & Fatigue Effects
Towers with high slenderness ratios are susceptible to vortex-induced vibration and buffeting. We assess dynamic amplification factors, natural frequencies and — where required — fatigue life of welded connections subjected to millions of wind load cycles.
Foundation in Difficult Ground
Tower foundations resist large overturning moments with relatively small footprints. We design spread footings, pile caps and rock anchor systems for any ground condition, coordinating geotechnical data directly into the structural model.
Antenna Load Integration
Antenna arrays, dish reflectors, waveguide runs and climbing systems all contribute to structural loading. We work from equipment specifications to integrate dead loads, wind-on-equipment and ice loads accurately into every node of the structural model.
Connection & Joint Design
Lattice tower joints — bolted flanges, gusset plates, splice connections — must resist combined axial, shear and bending forces. We detail every connection to EN 1993-1-8 and produce drawings ready for fabrication.
Existing Tower Assessment
Re-loading an existing tower with new antenna equipment is a common challenge requiring full structural assessment. We evaluate remaining capacity, identify critical members and propose upgrade solutions where required — without unnecessary full replacement.
What we design.
Lattice Towers
Self-supporting three-legged and four-legged steel lattice towers for telecom and broadcast.
Guyed Masts
Slender tubular or lattice masts stabilised by guy wire systems at multiple levels.
Monopoles
Tapered tubular steel poles for urban environments where footprint is constrained.
Rooftop Structures
Antenna frames, tripods and support steelwork mounted on existing building roofs.
