On the right track

The Chrisp Street mixed-use redevelopment in Poplar, London included a proposed basement adjacent to the Docklands Light Railway (DLR) in a shallow cutting. To gain planning approval it needed to be demonstrated that the DLR tracks would not suffer any significant movement due to construction of the basement.

A 3D FEA model of the proposed basement construction and adjacent DLR cutting and retaining walls demonstrated that the DLR tracks would not be adversely affected and planning approval was awarded. 

Highlights

• Detailed study of site investigation data and topography of the site and adjacent DLR cutting and gravity retaining wall.

• Creation of 3D FEA model of basement, DLR cutting and brick retaining wall.

• Simulation of basement construction, temporary and permanent supports and building loads.

• Prediction of DLR track distortion and damage assessment.

• Acceptance and award of planning approval.
