GROUND FLOOR PLAN TYPICAL FLOOR PLAN and benefit the working environment for tenants , shoppers and visitors alike . These include : lowflow water fittings , insulation for heat reduction or retention in accordance with exterior climatic conditions , the provision of carbon dioxide monitors in the basement for greater energy-efficiency with regard to the ventilation fans , internal blinds for glare control , split-unit air-conditioning with low-ozone depleting refrigerants , a general waste area for storage and sorting of waste for recycling and individual tenant operation of air conditioners for economic efficiency .
In addition , commissioning of all the building systems ( ie . mechanical , electrical , water and lift ) will be carried out in accordance with Chartered Institution of Building Services Engineer standards , a key component of an energy-efficient building , while power factor correction – to optimise the balancing of the electrical system for increased energy efficiency , is included in the design .
CIVIL & STRUCTURAL ENGINEERS REPORT The project parameters , and architectural characteristics , changed several times over the period between 2001 and the completion in 2015 . The most significant structural implication of the various interactions of the design related to the depth of basement and the requirements for lateral support to retain surrounding buildings and roads .
The eventual basement provided for 3 levels of underground parking . The lateral support was installed by Franki and comprised concrete gunite arches between ‘ CFA ’ piles . These were temporarily tied back by prestressed archors . These were destressed and rendered inert once the concrete structure was built .
The building is founded on ‘ CFA ’ piles . Suspended slabs comprised both conventionally reinforced concrete ( parking and ground floor ) and post-tensioned ( 1st to roof ).
