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.

Site Work By Risk Management Ltd

Intrusive fieldwork consisted of On-Site-UXO Support, 1 No. Cable Percussion Borehole, 4 No. Hand Augered Boreholes and Land Borne Gas Monitoring.

Laboratory Testing

Laboratory testing included Natural Moisture Contents, Quick Undrained, Triaxial Compression Tests, pH and Sulphate Tests and Waste Acceptance Criteria (WAC).

Tower Hamlets, Poplar

May 2022

RML were commissioned to carry out a Site Investigation for the demolition of an existing building and construction of two new build residential blocks in Tower Hamlets, Poplar.


Fieldwork was undertaken in line with British Standards BS 5930:2015+A1:2020. 3 No. Cable Percussion Boreholes, 3 No. Drive-in-sampler, Mechanically Excavated Trial pits, BRE 365 Soil Infiltration Tests, MEXE Probe CBR Tests, and Land-Borne Gas Monitoring were undertaken as part of the site investigation.

Ground Conditions

According to information published by British Geological Survey (BGS) the underlying geology at the site comprised Kempton Park Gravel (Thames Gravel Deposits) overlying London Clay of the Eocene Period.

Laboratory Testing

Natural moisture contents, Atterberg Limits, Quick Undrained Triaxial Compression Tests, Particle Distribution, pH & Sulphate tests, Chemical analysis, Asbestos Identification and Waste Acceptance Criteria (WAC) are the Laboratory tests undertaken for this project.
