1 Leadenhall Erith was awarded the contract to demolish a seven-floor building at 1 Leadenhall Court in the east of Holborn, London on behalf of Alinea. The site was a commercial office building of circa 190,000 sq. ft. The existing building consisted of seven floors with an additional roof and two basement levels. The site shares a boundary with the Grade II listed Leadenhall Market and Whittington Avenue which served access to this historic and important London landmark. In its place, a 36-storey tower will be erected including over 400,000 sq. ft of office space. Work started on the site in July 2018 and was scheduled to last 26 weeks in what was deemed a sensitive urban location due to its proximity to nearby structures, residential properties and established urban spaces. Erith erected site boundary hoardings that were compliant with the local council’s specifications. During the demolition phase, materials were processed at the workplace where possible and transported through a dedicated lift shaft/well hole to the first-floor level. The arisings fell directly onto a crash deck, where they were collected by skid steers. Arisings were then transported and loaded into the back of an eight-wheel rigid back HGVs from above via a well hole at the first-floor level. HGVs were directed back into traffic onto Whittington Avenue and Leadenhall Street by the site Banksmen/Traffic Marshals. During the demolition of the first-floor slab, arisings were collected and deposited into the back of HGVs using a 13t excavator machine with loading attachments. Initially, asbestos had to be removed from the building by the soft strip contractor with any residual asbestos being removed by Erith. Upon completion of that phase, the enabling works were then able to commence. Advanced demolition of the façade on Whittington Avenue was required to gain access to the site. Prior to this, a temporary steelwork goal post design was installed to transfer the loads to remove the columns and to support the structure. A BROKK was utilised for breaking a portion of the first-floor slab and the façade facing onto Whittington Avenue, which facilitated HGV access to the site. “A” frames were installed on the Leadenhall Market party wall. Openings within the slabs were broken out to allow the erection of the temporary steelwork. Prior to the start of hard demolition, a means of removing arisings from the site needed to be established first. Due to the size and location of the structure, lift shafts were utilised to transport arisings from the working floor level down to the first floor. Once the enabling works were completed, the hard demolition commenced. 8t machines with munching attachments were initially hoisted to the highest level using a mobile city crane, enabling demolition to commence for all roof plants and high-level structures. Mobile city cranes were mobilised on Leadenhall Street during a weekend temporary road closure and facilitated demolition of the atrium roof. Cut into smaller pieces to allow easier removal from the site, the steel sections were slung and burned from above allowing the city crane to lift and remove them from the site. This in turn enabled the erection of a site Tower Crane based at basement level. A 13t machine was used to load HGVs once demolition reached the first-floor level. Arisings were removed from the workplace using skid steer loaders and transported to the loading area by Whittington Avenue. It was from this location that arisings were loaded for removal from the site.
