CampbellReith was employed by Portakabin Ltd to provide geotechnical, environmental, civil, structural and transport engineering services for this £35m project to construct a new primary and secondary school. The school has 1,650 pupils and forms a major community hub for the Barking Riverside redevelopment.
The site had 12m of landfill placed since the 1960’s with the most recent being spoil from the Channel Tunnel. This surcharging of the site helped to compress deep layers of peat to stabilise ground settlements. Immediately prior to the school site redevelopment 4.5m of fill was removed. CampbellReith modelled the ground movement of the fill in order to provide criteria for the design of foundations, drainage and road infrastructure for the development.
We carried out extensive flood risk assessments and developed the drainage strategy including SuDS and attenuation provision in close liaison with the local authority. Our re-analysis of the site allowed development to proceed on this site that was previously classed as Zone 3.
We agreed acceptable forms of piled foundations and the materials management plan with the environmental health officer and the Environment Agency. The pile method was further constrained by the presence of large electric cables beneath the site, which used to supply the Ford Factory.
Our transport team carried out a full transport assessment and agreed the new school entrance positions off Renwick Road in liaison with Barking and Dagenham’s highways department and TfL (regarding wayleaves for the future overhead railway structure).
