Zip Textiles, Birmingham

The project was constructed as a two phase development. Phase 1 was constructed in 2007 at a cost of £5.9m with phase 2 extension following in 2014 at a cost of £3.6m.

Due to the poor ground conditions vibro ground improvement techniques were utilised. Due to the previous use of the site and prior to vibro works taking place a ‘proof dig’ of the site was completed with any remaining tanks or cellars removed and backfilled.

The structural frame comprised a steel portal frame solution spanning 35m with underslung laundry bagging system. A clear span composite sheet external cladding system was utilised to avoid the use of internal sheeting rails.

The ground floor construction comprised an insitu ground bearing slab solution with a large external service yard area designed for HGV use.
