Question: In which year was it announced by the authority to carry out the first elements of the concept?
About the article "Navy Pier", section "Plans".

Candidate passages:
On January 13, 2006, the Metropolitan Pier and Exposition Authority released plans for a major renovation of the Pier, which would include a monorail, a spokeless Ferris wheel, a roller coaster, floating hotel, and an water park with a Great Lakes theme.
The plan would include nearly double the current parking and a replacement theater with a greater capacity.
At the time of the announcement, a price tag of $2 billion was announced.
No concrete progress was made on those proposals, as the financial condition of the Pier suffered with the recession.
Following the reorganization of the agency that runs Navy Pier and McCormick Place, a new study was commissioned to reinvigorate the upgrade process.
The new study, by the Urban Land Institute, was released on November 11, 2010, and recommended a more modest set of enhancements aimed at retaining the Pier's role as a public space, rather than turning it into a theme park.
Suggested elements include a concert venue, an enlarged Chicago Shakespeare Theater space, new restaurants, a renovated commercial area around the Pier's entrance, and additional park-like features to bring people closer to the lake.
More grandiose possibilities, including the enlarged Ferris wheel and a hotel, are mentioned as more remote possibilities.
In March 2012 a competition led to selection of a design concept presented by a team led by James Corner of James Corner Field Operations that focuses on the Pier's role as a waterfront promenade.
In 2013 the Authority announced plans to carry out the first elements of a streamlined version of that concept, with reworked streetscape and a wider pedestrian space, moving tour-boat moorings to improve the view from a new central stairway centered on the Ferris wheel.
Work began during the winter of 2013-2014, with completion expected by Summer 2015.
Initially called the MSJ (Mid-Size Jet) Concept at NBAA 2007, the Legacy 500 was officially launched at EBACE in 2008, along with its smaller sibling, the Legacy 450.
It can be configured to carry up to 12 passengers, and can carry eight passengers over , or four passengers over .
The first prototype – S/N 00001 – was rolled out on 23 December 2011 to begin ground testing and systems evaluation.
Embraer's originally announced timeline for first flight and certification of the Legacy 500 had to be revised because software development for the aircraft's fly-by-wire control system was running behind schedule.
Rockwell Collins is supplying its Pro Line Fusion integrated avionics suite for the Legacy 500's cockpit.
The first engine run test was completed on 17 January 2012, and the aircraft's first flight occurred on 27 November 2012.
Certification of the Legacy 500 is currently planned for early 2014. 
The Authority was established on 19 July 1954 when the Atomic Energy Authority Act 1954 received Royal Assent and gave Authority the power “to produce, use and dispose of atomic energy and carry out research into any matters therewith”.
The first chairman was Sir Edwin Plowden, with board members running the three major divisions:  Industrial Group: Sir Christopher Hinton  Research Group: Sir John Cockcroft  Weapons Group: Sir William Penney UKAEA inherited nearly 20,000 employees, which doubled to 41,000 by 1961.
Most of UKAEA's early activities were related to the UK's nuclear weapons programme, and the need for plutonium, highly enriched uranium, and materials for hydrogen bombs.
Between 1952 and 1958 UKAEA carried out 21 nuclear weapon tests in Australia and the Pacific.
Following the Atomic Energy Authority Act 1971, the Authority was split into three, with only research activities remaining with the Authority.
The Radiochemical Centre Ltd took over production of medical and industrial radioisotopes and was later privatised in 1982 as Amersham plc.
British Nuclear Fuels Ltd (BNFL) took over nuclear fuel and weapons material producing activities: the manufacturing plant at Springfields, the enrichment plant at Capenhurst, the spent-fuel facility at Windscale, and the dual-purpose Calder Hall and Chapelcross military plutonium producing reactors.
The Atomic Energy Authority (Weapons Group) Act 1973 transferred responsibility for management of the UK's nuclear deterrent, including the Atomic Weapons Research Establishment at Aldermaston, directly to the Ministry of Defence.
In 1982 the Authority was involved in the creation of Nirex, to develop and operate radioactive waste disposal facilities in the UK.
The Atomic Energy Authority Act 1986 put the Authority into trading fund mode, requiring it to act and account as though it were a commercial enterprise and become self-financing.
The Authority was then split again by the Atomic Energy Authority Act 1995, with the more commercial parts transferred into a public company AEA Technology, which was then floated on the London Stock Exchange in 1996.
The nuclear facilities used for the UK's research and development program, which held large decommissioning liabilities, were retained.
The role of the Authority became to decommission these nuclear assets and to restore the environment around the sites.
From the early 1990s the Authority completed more decommissioning work than anyone in Europe, and had considerable success in regenerating former nuclear sites for commercial use.
Following the Energy Act 2004, on 1 April 2005 the UK's specialist nuclear police force, the UK Atomic Energy Authority Constabulary, was reconstituted as the Civil Nuclear Constabulary.
Responsibility for the force was also removed from the Authority and transferred to the Civil Nuclear Police Authority.
The 2004 Act also established the Nuclear Decommissioning Authority (NDA), which on 1 April 2005 took ownership and responsibility for the liabilities relating to the cleanup of UK nuclear sites.
The Authority became a contractor for the NDA for the decommissioning work at Dounreay, Harwell, Windscale, Winfrith and the JET facilities at Culham.
On 1 April 2008, the Authority announced a major re-structuring to meet its decommissioning obligations with the NDA.
A new wholly owned subsidiary, UKAEA Limited, was formed with established expertise from the existing company, to focus on nuclear decommissioning and environmental restoration management and consultancy in the UK and international markets.
At the same time, Dounreay Site Restoration Limited (DSRL) was formed out of the existing Authority team at Dounreay and was licensed by the Health and Safety Executive to operate the site and carry out its decommissioning under the Authority’s management.
DSRL became a subsidiary of UKAEA Limited.
In parallel with these changes, the site at Windscale in Cumbria was transferred to Sellafield Ltd, a site licence company under contract to the NDA, following close review and scrutiny by the Health and Safety Executive and environmental and security regulators.
The majority of Authority employees at the site transferred to Sellafield Ltd. On 2 February 2009, the Authority announced the next stage in re-structuring.
Research Sites Restoration Limited (RSRL), was formed from the existing teams at Harwell in Oxfordshire and Winfrith in Dorset and licensed by the Health and Safety Executive to operate those sites.
RSRL continued the decommissioning programmes for Harwell and Winfrith on behalf of the NDA.
RSRL also became a subsidiary of UKAEA Limited.
In October 2009, Babcock International Group plc acquired UKAEA Limited, the nuclear clean-up subsidiary of the Authority, including its subsidiary companies DSRL and RSRL.
In 2009 the Culham Centre for Fusion Energy (CCFE) was launched as the new name for the home of UK fusion research. 
The history of Rizza manifolds follows the history of the structure that such objects carry.
According to , the geometry of complex Finsler structures was first studied in the paper : however, Rizza announced his results nearly two years before, in the short communications and , proving them in the article , nearly one year earlier than the one cited by Kobayashi.
Rizza called this differential geometric structure, defined on even dimensional manifolds, "Struttura di Finsler quasi Hermitiana": his motivation for the introduction of the concept seems to be the aim of comparing two different structures existing on the same manifold.
Later started calling this structure ""Rizza structure"", and manifolds carrying it ""Rizza manifolds"". 
Immediately following the collapses, there was some confusion about who had the authority to carry out an official investigation.
While there are clear procedures for the investigation of aircraft accidents, no agency had been appointed in advance to investigate building collapses.
A team was quickly assembled by the Structural Engineers Institute of the American Society of Civil Engineers, led by W. Gene Corley, Senior Vice President of CTLGroup.
It also involved the American Institute of Steel Construction, the American Concrete Institute, the National Fire Protection Association, and the Society of Fire Protection Engineers.
ASCE ultimately invited FEMA to join the investigation, which was completed under the auspices of the latter.
The investigation was criticized by some engineers and lawmakers in the U.S.
It had little funding, no authority to demand evidence, and limited access to the WTC site.
One major point of contention at the time was that the cleanup of the WTC site was resulting in the destruction of the majority of the buildings' steel components.
Indeed, when NIST published its final report, it noted "the scarcity of physical evidence" that it had had at its disposal to investigate the collapses.
Only a fraction of a percent of the buildings remained for analysis after the cleanup was completed: some 236 individual pieces of steel, although 95% of structural beams and plates and 50% of the reinforcement bars were recovered.FEMA published its report in May 2002.
While NIST had already announced its intention to investigate the collapses in August of the same year, by September 11, 2002 (a year after the disaster), there was growing public pressure for a more thorough investigation.
Congress passed the National Construction Safety Team bill in October 2002, giving NIST the authority to conduct an investigation of the World Trade Center collapses.
