43-81 Greenwich High Road

Mixed-Use, Hotel

Greenwich High Road is a mixed-use development, consisting of residential, hotel and commercial units located close to the riverside and around major infrastructure.

This project required us to work closely with the Environment Agency, Thames Water, local highway authorities and Docklands Light Railway. Walsh designed a system of load bearing piles with a suspended basement slab to support the substructure. We used our expertise to design the upper floors of the larger blocks, including the hotel, as post-tensioned structures. However, the adjacent transport links and drainage systems presented significant challenges. High-pressure sewers ran through the site as well as abutments supporting the Docklands Light Railway above. Furthermore, the development was situated on a Brownfield Site directly bounded to the north and west by Deptford Creek.

The integrity of the existing river walls needed to be maintained during and after construction. Walsh developed a repair and replacement strategy for the various forms of the river wall. We worked closely with The Environment Agency and with their guidance we gained approval for the required works. Much of the masonry gravity wall was proven to be adequate simply by repointing, while sections of precast wall were repaired with stainless steel reinforcement and sprayed concrete facing. Where areas of wall were found to be uneconomical to repair a new secant wall was installed with tiebacks and anchor blocks.
