Salford Quays, Manchester

POSTED ON: 16/11/2021

The investigation work at Salford Quays, Manchester for the end client Vodafone Ltd, was designed to obtain information on the existing internal slab and subsoil conditions at this site for a slab capacity check and to provide information for subsequent foundation design.

Utility Search

A Utility Search was commissioned prior to any intrusive work, with plans supplied to RML from Vodafone and United Utilities Water Limited shown to affect the site.

UXO Report

A Detailed UXO Threat & Risk Assessment was commissioned for the site prior to intrusive work, the report concluded that the risk level for the site was ‘medium’ with the most probable UXO threat posed by WWII German HE bombs, whilst IBs (Incendiary Bomb) and British AAA (Anti-Aircraft Ammunition) projectiles (which were used to defend against German bombing raids) pose a residual threat. Consequently on-site supervision was required during intrusive work.

Intrusive fieldwork consisted of 2 No. concrete cores, 2 No. drive-in-sampler boreholes and 3 No. CBR tests at each location.

Laboratory Testing
