ADNEC was established in August 2005 under a decree issued by His Highness Sheikh Khalifa Bin Zayed Al Nahyan, President of the UAE and Ruler of Abu Dhabi.

ADNEC's initial task was to develop a venue that would replace the old Abu Dhabi International Exhibition Center and attract more meetings, incentives, conferences and events into the emirate.

The centre's event area will be extended by 50 per cent and include a 5,000-seat, purpose-built convention center, ICC London ExCeL, by spring of 2010.

[5] Enabling works to double the capacity of the existing venue to 12,000 m2 (130,000 sq ft) are ongoing and construction will commence in late 2009 or early 2010.

It is part of the Al Ain Convention Centre district, which covers an area of 275,000 m2 (2.96 million sq ft), and is estimated to cost AED 3.5 billion.

Upon its completion, Capital Centre will comprise twenty-three towers, including six branded hotels, four commercial buildings, eight residential and serviced apartment complexes, and 5 mixed-use developments.

Investigation and evaluation, which was made by a Guinness appointed awards committee, started in January 2010, when the exterior of the 160-metre (524.9 ft), 35-storey tower was completed.

The core, deliberately built slightly off centre, has straightened as the building has risen, compressing the concrete and giving it strength, and moving into (vertical) position as the weight of the floors has been added.
