80 Oxford Street

Complex temporary works on extremely confined site

This retail and commercial development on Oxford Street was for Great Portland Estates. Walsh were employed by Brookfield to deliver a complex temporary works solution for a very confined site.

These works included a façade retention and lift along Dean Street, which at the time was also entirely confined by the adjacent Crossrail station development.

Other works were for the basement excavation temporary works, party wall support and designing of the flying gantry to hold the site offices in place over Oxford Street.

The Dean Street façade retention required a 30m-long section of façade between 1st and 4th floor to be held in place during the demolition works and basement excavations. Once the new superstructure was built the whole façade was then raised by 900mm to align with the new envelope design. This was achieved by designing a principal support frame and a second frame behind the façade which was jacked up the face of the support frame.
