Leadenhall - Keltbray
150, Leadenhall / 6-8, Bishopsgate, London.
Project:
The project undertaken by Keltbray includes the demolition of the existing buildings, at 8 and 20 storeys rising to 220.0m into the city skyline. The site will provide and allow the construction of a redevelopment scheme to include offices, shops, a café and restaurant along with a roof top pavilion.
Solution:
The development site is approximately 0.34 hectares and is currently occupied by two office buildings on the corner of Bishopsgate and Leadenhall Street. The first building is 150 Leadenhall Street which was completed in the 1970s and comprises 5,296 sqm of office floorspace within an 8-storey building that has frontage to both Leadenhall Street and Bishopsgate. It is currently under multiple occupancy. The second building is 6-8 Bishopsgate completed in 1980 and is 20 storeys with a frontage to Bishopsgate and has been vacant since March 2017.
The site is bounded to the south by Leadenhall Street, to the west by Bishopsgate, to the north by the 22 Bishopsgate site, to the east by existing commercial uses and the 122 Leadenhall Street development site [The Cheesegrater].
Specs:
The scaffold constructed from Tube and Fittings totals over 13586m2 with over 4300m of beam work. The demolition scaffold started erection from ground level, with a pedestrian walkway gantry situation on the main pavement level outside 150, Leadenhall. At storey levels 5 and 13 a series of steelwork needles were erected and cantilevered from within the structure to provide support, via a series of 750 alloy beams, to the on-going scaffold. The scaffold was completed after the completion of 3no. levels of protection fans and a goods passenger hoist with full encapsulation with plastic sheeting.
