65 - 67 Scrutton Street, London EC2

Client : Gansevoort Hotel Group
Value : 2.55 M

Overview:

67, Scrutton Street was a three story reinforced concrete, brick clad unassuming structure on the corner of Curtain Road, East London. The project was soon to be the location of a new boutique hotel.

Scope of Works:

Demolition

  • The removal of existing  asbestos materials.
  • Liaise with party wall surveyors and Local Authorities, then design and install temporary works to the party wall and basement retaining walls.
  • Demolition of the existing three storey former office building, down to the underside of the existing single basement slab.
  • Pile probing together with the formation of guide walls to the perimeter of the site in preparation of the secant piled wall.
  • Back filling of the existing basement with crushed demolition arisings to form a piling platform.
  • Installation of a noise and vibration monitoring regime.

Piling Works

  • Formation of the guide wall ready to accept the secant piled wall construction.
  • Provide access for the piling rigs and associated plant including a swept path analysis for vehicle movements.
  • The procurement of the piling contractor.
  • The design and installation of 150 linear meters of 600mm diameter secant piled wall to the perimeter of the site.
  • Installation of perimeter temporary works to retain the secant piled wall.
  • Noise and vibration monitors strategically placed to record resultant noise and vibration generated during the works.
  • Specific forms of non percussive demolition techniques were implemented to reduce noise and Vibration. These included hydraulic cracker attachments to demolition plant and saw cutting to isolate the structure adjacent to the party wall.
  • The use of temporary acoustic blankets were used to dampen any noise produced close to surrounding residential properties.
  • Due to the sensitive location of the site and the position of  the surrounding residential buildings, care was taken to liaise and discuss works to be carried out with the local community on a regular basis, highlighting potential disruptive issues.

Comments

  • One of John F Hunt’s first piling projects.
  • The successful completion of the project with a very restricted site located within a sensitive residential area.
