Caledonian Rd (Demolition & Asbestos Removal)

We were appointed by London Square to act as Principal Contractor for the demolition phase of the redevelopment.

Downwell were appointed by London Square to act as Principal Contractor for the duration of the demolition phase of the Caledonian Rd project.  The site was positioned within a stones throw of the infamous Pentonville prison. We were required to demolish all of the structures on the site in preparation for redevelopment of the site. This included a former British Transport Police station.

Scope of Works

  • We firstly had to liaise with the adjoining properties along Caledonian Rd regarding their fire escapes. The fire escapes of these commercial premises exited into the site and we needed to set up a safe means of exit. This fire escape route was set up using Herras fencing, debris netting, lighting and signage to ensure that anyone wishing to exit in an emergency could safely get onto the street and not into the demolition site.
  • There were large amounts of asbestos containing materials throughout the site. These were removed by Inner City Environmental who are a licensed asbestos removal contractor with a 5 year License. All asbestos containing materials were taken to a licensed waste facility.
  • A small amount of scaffolding was required to protect members of the public walking past the site in certain areas. This scaffolding was erected by Inner City Scaffolding and was completely encapsulated using flame retardant Monarflex.
  • The structures were demolished using standard height demolition plant. A variety of hydraulic attachments were used to shear the steel beams and columns. Jaw munchers were then used to munch through the masonry walls and concrete beams. Smaller machine were then used to further process the materials and load them into bins.
  • Due to the location of the demolition to the live neighbouring structures the suppression of the dust during the demolition phase was a big priority. The dust was suppressed using water mist machines and by attaching water hoses to the arms of the machines.
  • Once the buildings had been reduced the ground slabs and foundations had to be removed. These were dug out of the ground and then broken into small sections using a hydraulic breaker. All of the concrete and masonry was then crushed to a certified 6F2 aggregate to be left on site and used during the construction phase.
  • Some of the concrete foundations were within a close proximity to neighbouring retained structures. These concrete foundations were saw cut using a wire saw to cut the foundation away whilst not undermining the neighbouring building.
