TDS4 | Structural Design

Having the total connection design package done by one partner will speed up your process

TDS provides full structural steel connection design services for structural steel fabricators and main contractors. Having a specialised connection design team with fabrication and erection experience enhances our understanding of how structures are designed, fabricated and erected, and enables us to design structurally efficient connections.

We have developed several design tools that enable us to evaluate multiple connection alternatives to determine the most efficient, economical and safe connections. We are well versed in Tekla modelling and use this software for particularly difficult or complex connections, ensuring that the connections can be fabricated and easily erected in the field.

Our structural design team are lead by one of the sectors most respected engineers. Using the latest techniques in Structural steel design we work with some of the highest profile names in the sector with very exciting architectural steelwork design projects being launched.

5 Hanover Square, London

Working in collaboration with Squire & Partners Architects for client Stanhope, TDS designed, developed and detailed a series of double sloped panel support frames to the roof of an existing building in the heart of London. As far back as 2011 we were utilising BIM techniques including the production of a data rich 3D model for the structure which was utilised by the wider design team to ensure that all roof top plant and equipment would not clash with the new support structure.


Avonmouth Bridge, Bristol

Working in collaboration with The Highways Agency and Mott McDonald, TDS were engaged to design, develop and detail a series of walkways and crows nests along the length of the Avonmouth Bridge which spans the River Avon. All work completed was BIM Level 2 compliant with full manufacturing information as the ultimate output.


Salford Arch

TDS were successful in winning the Salford Arch advertising structure project – the first purpose built digital advertising arch in Britain. A complex engineering project – an 18m high arch spanning 38m across the M602 with 200m2 of advertising space, we provided the initial conceptual drawings along with a full design and manufacturing package to enable the accurate fabrication and installation of this iconic structure which is seen by more than 80,000 people a day.
