Case Study – BAKER MCKENZIE

CAT B Fit Out – Scope of Works

 

  • Validation of existing services – No record information and an installation dating pre 1990 made this an extensive task.
  • Point cloud survey to produce .dwg drawings.
  • The installation of site temporaries.
  • Refurbishment of existing distribution boards.
  • Validations revealed multiple supplies were required to be maintained throughout the duration of the works; therefore, we installed a temporary solution during an out of hours shutdown to facilitate this.
  • New underfloor busbar system.
  • New desk power and power to meeting rooms, etc.
  • Power to a newly constructed tea point and breakout area.
  • Mechanical power requirements:
  • Relocated existing VAV units

Project Details: Baker McKenzie – Level 4, 100 New Bridge Street
Contract Value: £650K
Duration: 5 months: November 2018 – March 2019
Works Description:
CAT B fit Out
Comms Room Rationalisation – simultaneous refurbishment and decommission of 2 separate comms rooms into 1

Comms Room Rationalisation – Scope of Works

 

  • Validation of existing services – Much like the CAT B scope, there was no record information and the age of the installation made this an extensive task.
  • The existing arrangement consisted of 2 comms rooms that the client wished to rationalise to a single room, whilst also upgrading the remaining comms room to increase server rack provisions and cooling requirements.
  • Validations revealed a large number of supplies that were required to be maintained throughout the duration of the project until the final migration of server equipment. Therefore, a robust temporary solution was installed to utilise generator backed supplies from separate areas of the building in order to keep the necessary supplies live throughout the course of the project.
  • Multiple shutdowns were required and detailed risk management strategies were implemented.
  • New comms room installation required the removal and replacement of the existing UPS system, with a modern N+1 system.
  • New sub mains cabling was installed from existing tap off units at different locations within the building.
  • An insufficient number of rising busbar tap off units were available to facilitate the new installation and, due to the age of the existing busbar, new tap off units were not available within the project time constraints. Therefore, we installed 2 busbar chambers to enable temporary dual operation of a single tap off unit for 2 separate supplies.
  • New lighting, containment and small power throughout.
