Overview

Extensive reclamation, reuse and recycling of materials during our soft strip phase was a defining aspect of the project. This resulted in an agreed demolition methodology, and approval of pre-commencement documentation, allowing a seamless transition from pre-commencement to site works.

Relevant Experience

Our works at 30-duke-street-st-jamess include soft strip, demolition to basement, excavation, new concrete foundations, one level basement box, slipform core and installation of ground floor slab.
Circular economy is always at the centre of all of our projects, and we are particularly proud of the impressive salvage opportunities which we have identified and acted on at 30-duke-street-st-jamess.
For instance, we have been removing the Portland stone cladding from the external façades on Jermyn Street, Duke Street and Piccadilly elevations. The stone is intended for reuse in the main building façade. Glass blocks will also be removed from the 48-50 Jermyn Street south façade, which have potential reuse in the final building.
In addition, the marble main stairwell will be salvaged, with 80 panels being set aside for reuse in the new development, and up to 1 ton of broken marble pieces being reused as terrazo. External glass on all elevations has been salvaged and we are engaged in a take back scheme with Saint Gobain, who will recycle the glass.
We have also had a total of 833 items taken from site for reuse, with destinations including Hackney City Farm, photography studios and workshops for underprivileged emerging artists using excess Portland stone which was damaged during removal. We have donated rubber matting and old carpet to Hackney City Farm for their older animals, which provides them with a more comfortable living space.
These efforts are some of many which we are undertaking at the 30-duke-street-st-jamess project, and serve as a shining example of our commitment to ensuring that our works leave a positive legacy in the surrounding communities, and our unwavering dedication to circular economy.
We have ensured that works are being carried out concurrently, with civil works, namely the nine storey reinforced slipform core, being done at the same time as demolition. This adroit approach will save at least 6 weeks on the programme.
We have successfully diverted 99.9% of nonhazardous waste from landfill and have allocated a significant number of materials for reuse on site and enabled the reuse of materials offsite.
