Phase 3 of the Battersea Power Station Redevelopment is a mixed-use precinct consisting of residential, retail and commercial uses, and features the distinction of being located adjacent to the Grade II* listed Power Station building (including the sensitive southern wash tower structures) and Network Rail assets (running tracks and a viaduct structure). The Phase 3 development is also alongside and directly above the new Northern Line Extension (NLE) station box. Phase 3 features three 17-level buildings by acclaimed architects Gehry Partners and Foster + Partners, a retail podium, and a three-level basement.

RBG has lead the geotechnical delivery on the Phase 3 development over the past 3 years, providing RE support during sub-structure works, including reviewing the: bored piles, retaining walls (secant and steel sheet piles), large walling beams, ground anchors, ground water proofing and deep excavation works. RBG contribution was instrumental to unlock issues related to the construction of bored piles that had the potential to lead to significant programme delays and additional construction costs. RBG’s geotechnical engineering team has proposed an alternative approach to stabilising the adjacent Power Station wash towers during basement excavation, leading to the deletion of numerous substructure and temporary works elements. The interface with the Power Station was carefully managed and ground movement assessments were completed to validate the proposed alternative solutions and the anticipated impact on the listed structure.

RBG has delivered ground movement assessment to predict the structural impact on the adjacent Network Rail (NR) viaduct and bridge. There is also a significant and complex interface between the development and the new London Underground station that will form the terminus of the Northern Line Extension. RBG has led process to gain technical approval for the construction of the adjacent basement together with a series of large diameter piles that may be formed in between the NLE tunnels and at a clear distance of less than 1m from them. Without the use of detailed ground-structure interaction analysis, our client’s proposals would not have gained approval from London Underground and the scale of the development would have had to be significantly reduced.
