The Global Academy will be built in the London Borough of Hillingdon at the Old Vinyl Factory site in Hayes .
As part of the project, Portakabin will carry out complex groundworks, extensive excavations for district heating, and build a new sub-station.
A significant proportion of the work will be completed offsite at the Portakabin Group factory in York in order to meet a challenging programme to open in September for the start of the 2016-17 academic year.
The UTC will offer academic and vocational training for 14-19 year olds who want to work in the broadcast and digital media industries.
Designed by the Portakabin Group and architects Surface to Air, the technically-complex building will deliver a demanding acoustic specification, with triple glazing and specially-engineered air conditioning.
Simon Ambler, Director of the Portakabin Group, said: “This is a hugely significant project for the construction sector. It demonstrates the architectural flexibility of a highly-engineered Yorkon off-site solution from the Portakabin Group and how an outstanding building design can successfully integrate different construction methods.
“It also illustrates really well how we can deliver an inspiring, animated and intelligent building in a very short timescale and on a highly complex site.”
