4. The 539 pile foundations - each at an
average depth of 18 metres
3,300 tonnes of steel and
1,948 coffered concrete floor slabs
which make up the structure of the
building.
The building includes 329,218ft² of
office space spread over the basement,
lower ground, ground and 14 upper
floors.
The column-free structure of the
building enables an extensive range of
subdivisions to be made from a full
floorplate down to suites of 3,000ft².
Each floor can be subdivided into six
zones, providing maximum
occupational efficiency and flexibility.
Construction work began in July 2010

11. The Combined Heat and Power Plant
(CHP), powered by pure vegetable oil
produced by the cooperative farms,
provides most of the electrical and
heating requirements for the new
building with surplus energy that is fed
back at the national level. Grid.
Other energy efficiency features
include:
Heat recovery from computer systems
that will also help heat the building.
Low energy LED lighting and computer
equipment and systems.
High efficiency elevators for passengers
and services.
Underground ducts to bring fresh air
through a heat exchanger.
The project used a number of
initiatives to minimize fuel and energy
use during construction. The on-site
cabins were heated from a dedicated
gas supply rather than inefficient
electric heaters. In addition, a rental
store was established on site that
provided materials and tools, saving
time and costs, as well as reducing
fuel and CO2 emissions.

The trash pallets were recycled to create unique
and stylish furniture for use in the building once
they were vacated. Most of the remaining waste
was recycled through waste separation,
including a can collector and cardboard
compactor on site. Cardboard collected at the
site was recycled at the customer's recycling
facilities that were located adjacent to the site,
helping to further reduce carbon emissions and
transportation costs
.
Precast elements are used, such as cold-formed
beams and bathroom modules, which decreased
the number of material deliveries and reduced
the waste associated with on-site assembly.
