Walkover Survey
A walkover survey was carried out by an RML Engineer to establish if contamination is present from any undocumented practice or industrial use of the land and surrounding land and if necessary to confirm the accuracy of the information obtained from elsewhere as part of the Preliminary Risk Assessment (PRA) data gathering process . A visual assessment of the land to check for signs of industrial activity, landfilling, fly tipping , fuel storage, fuel tanks, asbestos related materials or any land contamination was undertaken and a photographic record made to provide evidence to show the condition of the land at the time of the Walkover Survey.

Telecommunications Node, Poplar
December 2022
RML were commissioned to carry out an intrusive site investigation designed to obtain information on the sub-soil conditions at this site, together with some laboratory testing, in order to provide baseline information for any subsequent foundation design by others.
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.
