Dramatic challenges on new BBC studios
“Since the BBC decided on this site we have worked closely with its programme-makers to ensure they get exactly what they need,” says Bay Associates Director Martin Watkins. Steel frame trusses with typical spans of 25-30m help support the large imposed loads delivered by the studio lighting, camera and air-conditioning systems.

At level 70 the structure switches back to steel as this area accommodates a triple-height viewing gallery. Above this sits the 15-storey high prefabricated spire. This houses a second triple-height viewing gallery at its base which is partially open to the elements at the sides. Level 87 is the top storey. Above this steelwork continues to support the Shards’ shards of cladding that terminate at different heights to give people the impression the building fades into the clouds.
Glasgow cheers completion of vital M74 link
Port Eglinton viaduct is the largest bridge on the project. It is 750m long and carries the M74 over a number of streets and railway lines including the West Coast Mainline. For much of its length the steel box girders were lifted into position using a 1200t crane positioned at street level, but a 200m section was built by launching the beams, using jacks to pull them over the roads and rail lines.

But this is no ordinary steel framed building – as the huge 60-tonne prismatic girders that provide the support for the street level slab show. Encased in concrete, these elements have been craned into position by steelwork specialist Bourne Steel with the help of a 600-tonne capacity crawler crane sitting on the site.
