1-5 London Wall – Phase 2

Strip Out & Enabling

Client: Endurance Land
Project: 1-5 London Wall – Phase 2

Brief Description:

Acting in the capacity of Principal Contractor, KpH were engaged by Quantem Consulting, on behalf of our Client, Endurance Land, to undertake Phase 2 of 2 which consisted of an 17 week Sympathetic Strip Out and Enabling project at 1-5 London Wall Buildings; a Grade II listed property (built in 1901). The building is comprised of circa 209,307 ft² of office, A1, A3 and ancillary accommodation arranged over basement, lower ground, ground and eight upper floors.

To complete the works successfully, KpH had to take appropriate steps to comply with the Grade II listed regulations and ensure that the structure and key features were preserved and protected. These included parquet and marble flooring, cornicing, skirting and staircases.

Parts of the building remained tenanted at the start of the works so they required a considered approach. Strong leadership was required throughout the project; a team of managers and supervisors worked together to coordinate three different asbestos contractors, electrician, mechanical engineers scaffolders and a structural investigation contractor.

KpH worked closely with the City of London to obtain the correct permits for hoarding and a gantry facility. The waste was primarily removed via this gantry which was specifically designed to allow the public and neighbouring trades to go about their business as usual.

Licensed Asbestos Removal Works

KpH have accommodated an extensive Licenced Asbestos Removal Package alongside our programme of strip out works. These works were mainly located within the basement and despite a thorough R & D Survey prior to our commencement on site, additional asbestos debris were found. The asbestos and strip out works were required to be re-sequenced to mitigate as much as possible any impact on programme, however inevitably the volume of asbestos discovered required an extension to our original programme. The licensed works were undertaken by our supply chain partners, Inner City Environmental who have successfully co-ordinated the works during phase 1 when the building was occupied by tenants and phase 2 to facilitate our on-going strip out activities.

Lift removal

In addition to the strip out works back to shell and core, with the exception of listed materials, the scope require the removal of 7 landlord lifts spanning from basement to 6th floor, 4 tenants lifts spanning from basement to second floor,  a dumb waiter, barrel lift and redundant external goods lift. These works required an installation of 3 phase power to supply the 2T electric chain hoist.

Structural investigations

During our time on site, KpH were able to support client appointed on-going structural investigations to inform design and structural assumptions. These investigations were undertaken to columns , beams and slabs . In addition a number of trial pits were opened up across site by both parties and careful co-ordination was required to achieve successful results.


The project was enrolled on a sustainability programme which meant as part of the project, we would look to dismantle for re-use as many items as possible. To achieve maximum social impact KpH partnered with Globechain, a market place that connects construction projects with charities and community organisations and were able to donate the items you see listed to the right. This initiative will be adopted on the next phase also due to it’s success.
