TECHNICAL SPECIFICATION

STRUCTURE

The construction of the 195-meter tower will comprise of reinforced concrete shafts with walls and columns, connected in a spatial arrangement with floor slabs.

LOADING PROVISIONS

  • Office floors: 1.1 kN/m2 dead load and 3.0 kN/m2 live load,
  • Storage or server areas at office floors in zones around
  • Plant floors: 2.7 kN/m2 dead load, and 10.0 kN/m2 live load.

LOADING BAYS AND PARKING FACILITIES

The loading area is located at level -1 and services the whole building. Parking facilities have been provided as follows:

  • 500 bicycle spaces with showers and lockerfacilities,
  • 431 secure car parking spaces on five underground levels,
  • 3 short time car spaces available at ground level.

LIFTS

The passenger lifts within the building incorporate the latest destination and access control systems, allowing lifts to function more efficiently and reducing waiting/travelling times, also allowing enhanced security control and personalization.

PERFORMANCE

The lift provision within the building has been specified to meet the following performance characteristics:

  • A workplace density of 1:10 m2 (allowing 20% absenteeism),
  • Up-peak handling of 15% of the building population in a 5 minute period,
  • Up-peak average waiting times of less than 25 seconds,
  • 5 minute group handling capacity more than 13% of zone population.

OFFICE PASSENGER LIFTS

Two separate groups of lifts dedicated to lower (LOW RISE) and higher (HIGH RISE) floors in the office tower.

  • Seven passenger lifts rated at 1,600 kg (21 persons), speed of 3 m/s serving lower office floors,
  • Seven passenger lifts rated at 1,600 kg (21 persons), speed of 7 m/s serving upper office floors,
  • Car size 2,1 m (w) x 1,6 m (d) x 2,7 m (h).

FIRE FIGHTING / GOODS LIFTS

All lifts in the building are fire protected and can be used for goods.

  • Two lifts rated at 2,500 kg (33 persons) with a speed of 4 m/s,
  • Car size 1,8 m (w) x 2,4 m (d) x 2,7 m (h).

CLADDING

The cladding and the facade has been designed to achieve the requirements of the latest building regulations and achieve maximum performance for BREEAM.

PERFORMANCE

The design supports the following:

  • U-value (vision glazing): 0.9 W/(m2K) (triple glass to be used - part l 2010 compliant),
  • U-value (non-vision glazing): 0.25 W/(m2K) (double glass and mineral wool to be used - part l 2010 compliant),
  • Air permeability: 1.5 m3/m2/h (part l 2010 compliant),
  • Water tightness: RE1200,
  • G-value: below 0.35,
  • Lt-value: above 52%.

There is a roof mounted trolley to allow facade cleaning and maintenance, including an additional lift in case the glass needs to be replaced.

TOILETS

Toilets on all office floors with an occupancy of 1:10 m2, with a 50/50 male/female split.
