The Dixons Academies Trust chose the former
Bradford College site to be the location for their
4th Free School, the Dixons McMillan Academy.
It was a building very much in need of conversion in
order to provide a modern, fit-for-purpose learning
environment for 11-18 year olds. In addition to the
conversion a double-height, multi-use entrance
hall was added to the existing structure and a
freestanding, new build sports hall was added to
the site.
TDS were asked to design the additional steelwork
required to strengthen the existing building
throughout the extensive renovation and remodel.
We were also commissioned to provide a new access/
escape staircase for the double-height entrance area
as well as plant access stairs to the roof.

We received, from our contractor client, all necessary
site surveys of the demolition works and designs for
the steelwork. From this, using Tekla Structures, we
produced a comprehensive set of steelwork details
for approval. After the sign-off, we issued the designs
to the fabricator complete with all information
to ensure they could be correctly and efficiently
assembled on site.
