Question: When did Stage I of Civil & Civic begin?
About the article "Sydney Opera House", section "Stage I: Podium".

Candidate passages:
Stage I commenced on 2 March 1959 with the construction firm Civil & Civic, monitored by the engineers Ove Arup and Partners.
The government had pushed for work to begin early, fearing that funding, or public opinion, might turn against them.
However, Utzon had still not completed the final designs.
Major structural issues still remained unresolved.
By 23 January 1961, work was running 47 weeks behind, mainly because of unexpected difficulties (inclement weather, unexpected difficulty diverting stormwater, construction beginning before proper construction drawings had been prepared, changes of original contract documents).
Work on the podium was finally completed in February 1963.
The forced early start led to significant later problems, not least of which was the fact that the podium columns were not strong enough to support the roof structure, and had to be re-built.
The Opera House was formally completed in 1973, having cost $102 million.

"Sam" Hoare, the Hornibrook director in charge of the project, provided the following approximations in 1973:Stage I: podium Civil & Civic Pty Ltd approximately $5.5m.
Stage II: roof shells M.R.
Hornibrook (NSW) Pty Ltd approximately $12.5m.
Stage III: completion The Hornibrook Group $56.5m.
Separate contracts: stage equipment, stage lighting and organ $9.0m.
Fees and other costs: $16.5m.
The original cost and scheduling estimates in 1957 projected a cost of £3,500,000 ($7 million) and completion date of 26 January 1963 (Australia Day).
In actuality, the project was completed ten years late and more than fourteen times over budget. 
The Company was originally founded by Dick Dusseldorp in 1951 on behalf of the Dutch building companies "Bredero's Bouwbedrijf" of Utrecht and "The Royal Dutch Harbour Company" as an Australian-based building contractor.
Its first contract was to supply and erect 200 prefabricated houses for the Snowy Mountains’ Authority which had been established by William Hudson, engineer of the Snowy Mountains Scheme.
Hudson's greatest obstacle in the completion of the scheme was the provision of labour and materials.
Without a resolution to these two problems the realisation of the project was doubtful.
But 31 year old Dutch immigrant Dick Dusseldorp conceived a plan to prefabricate frames for worker housing in Finland, plumbing in England, ship materials via Cooma and recruit labour from the Netherlands to erect the homes.
Dusseldorp established 'Civil and Civic' to take on and manage the multi-million-dollar contract.
Civil and Civic went on to become Australia's leading provider of project management services in the construction industry, delivering a number of landmark projects including Stage I of the Sydney Opera House, Australia's first high-rise (Caltex House), and the world's first high-rise strata title apartment building (Blues Point Tower).
In 1961 Civil and Civic was acquired by Lend Lease Corporation, but the company continued to trade under the Civil and Civic name for some time, also constructing the world's tallest lightweight concrete construction building (Australia Square), and the tallest building in the world outside North America (MLC Centre) at the time of completion.
In 1999 Lend Lease Corporation acquired P&O's Global Project Management Company, Bovis, rebranding the business as Bovis Lend Lease.
The Australian operations of Civil and Civic were merged with the new subsidiary, effectively ending the use of the original company name. 
UCP has a Women organisation and a Youth Organisation in its structure.
In 1995-2000 youth organisation of UCP was "Civil Forum", which left UCP during Parliamentary elections of 2000, when UCP bycotted it.
Culadzimer Novosiad, chairman of Civil Forum got a place in Parliament than.
In 2000-2000 youth organisation called itself "UCP Youth", but was rather an artificial structure in the party.
In 2000-2009 YCSU Young Democrats was officially a youth wing of UCP, but in February 2009 at the congress of YCSU Young Democrats a decision to stop cooperating with party was taken.
Some members of YCSU Young Democrats did not support the decision to restrain cooperation with United Civic Party, left YCSU Young Democrats, and stayed as UCP Youth. 
The Civic Forum for Northern Ireland is a consultative body in Northern Ireland created under the Good Friday Agreement and consisting of members of various civil bodies.
It had no legislative or governmental powers.
The Forum was set up in October 2000.
It was initially chaired by Chris Gibson.
Other members included Gary McMichael.
The body was suspended along with the Northern Ireland Assembly in 2002.
In June 2007, the Office of the First Minister and Deputy First Minister stated, "At this stage we are simply ascertaining how many of the current members are available and will decide then whether to recall them based on their responses.
"In 2011, in response to questions in the Northern Ireland Assembly, the First Minister said:Following the restoration of devolved powers in May 2007, the then First Minister and deputy First Minister considered the position of the Civic Forum in the re-established devolved arrangements and decided to commission a review of the effectiveness and appropriateness of its structure, operation and membership.
The review was also to make recommendations on the most appropriate mechanism for engaging with civic society...
There was no widespread desire for a return to a structure of the size and expense of the Civic Forum as it had previously operated.
Accordingly, there have been no meetings of the Civic Forum during this Assembly mandate, which has also resulted in considerable savings to the public purse.
... At the same time, I do not, in any way, want to leave the impression that we want to reduce the connection with our community.
We want to continue having consultation.
For instance, because of the economic downturn, the deputy First Minister and I brought together a group of stakeholders from across the community.
We did that without those people getting or seeking any expenses, which indicates that people are willing to give their views without having elaborate and expensive structures.
In April 2013, the Assembly voted to recall the Forum.
