House       
by Anne Watson
    A new book from Powerhouse Publishing offers a unique account of the  Sydney Opera House and is essential reading for anyone looking for a  fresh insight into the complex history of this iconic building. The  following excerpt is the introductory essay to the book, by Anne Watson  (Ed.)   
The project that generated this book was conceived as a 50th  anniversary celebration of the competition for a 'national opera house'  in Sydney — the start of it all! The year 2006 marks half a century  since the NSW Government launched the competition early in 1956 to give  Sydney a music and performance centre. It was during 1956 that the  38-year-old Jørn Utzon created the designs for his visionary building in  his modest office in Hellebæk, Denmark. And it was at the end of 1956  that he packed up his 12 drawings and sent them off to Sydney. Allocated  the sequential number 218, Utzon's entry was one of the last in before  the competition closed on 3 December 1956. Less than two months later  scheme number 218 was pronounced the winner, and the story of Australian  architecture entered a new trajectory.
While Utzon and over 200 other architects were completing their  competition schemes in 1956, Melbourne was hosting Australia's  first-ever Olympic Games. Staged in November, the Melbourne Olympics  drew world attention to a country not otherwise much in the news and  contributed significantly to the nation's growing post-war confidence  and its sense of place in the international community. On a local level  it is tempting to speculate that, in the time-honoured spirit of rivalry  between Melbourne and Sydney, part of NSW Premier J J Cahill's  motivation in initiating the competition was to regain ground lost to  Melbourne when it won the Olympic bid.
Whatever the repercussions of the Olympics, the mid 1950s were pivotal  years for Australia's future. An expanding post-war economy was fuelled  by unprecedented levels of immigration from Europe, an injection of 'New  Australians' who were to change the face of the country's society and  culture. Many were to get jobs as construction workers on the Opera  House during the 1960s, for some a defining experience that helped  secure their attachment to their adopted country. 
While emigrant construction workers were helping to build Australian  cities, emigrant architects and designers were beginning to make their  presence felt on a more modest scale. Architects like Harry Seidler,  Henry Epstein, George Molnar and Peter Kollar brought from Europe and  America important modernist design concepts that reinvigorated Sydney  architecture in particular. Significantly, a high proportion of these  architects were sufficiently attracted by the challenges of the opera  house competition to submit entries. Kollar (with fellow Hungarian  Balthazar Korab) and Seidler’s schemes were among the 14 entries  commended by the competition judges. Not surprisingly perhaps, it was  these very same architects who vigorously and publicly championed Utzon  in the bitter aftermath of his 'resignation' from the Opera House  project early in 1966. At stake was not just the future of the great  building, but the issue of creative integrity, traditionally respected  in Europe, often abused and misunderstood in Australia.
Sydney's European émigré architects would also have been well aware of  the crossroads that international architecture had reached by the mid  1950s. Glass-box modernism, dominant for the last 30 years, was under  threat from a new, more humanist design language that embraced  expressionism and challenged Mies van der Rohe’s axiomatic 'less is  more'. Peter Kollar alluded to the debate in his review of the  exhibition of the opera house competition entries early in 1957 and was  one of the first local architectural writers to recognise Utzon's  winning design as an important statement in the newly-liberated design  language.
Much has been made of the 'unexpectedly' imaginative and daring choice  of the four competition judges early in 1957. In the 1950s Sydney was  barely on the architectural map — yet clearly international and  locally-generated social and cultural changes were beginning to stir  things up. If nothing else, Utzon's opera house was a precocious signal  of the dawn of a new era for Australian society, a beginning we are  still reaping the benefits of today. Perhaps our 'connectedness' with  this beginning has contributed to our continuing regard for and  attachment to this timeless building, an enduring admiration that also  recognises it as a building far in advance of its time.
The competition of 1956 was the point of departure for this book, but it  is only the first chapter in the long and dramatic story of the  construction of the Sydney Opera House. Jørn Utzon's career, the  unfolding architectural narrative of the building and its place in the  history of architecture have been broadly documented in a range of  publications. But any great feat of imagination and ingenuity generates  sub-plots, and the Opera House, perhaps more than any other  twentieth-century structure of its stature, has generated a lot. It is  the many untold layers of this story that Building a masterpiece  explores. These are the stories of the individuals whose careers were  made or broken by the Opera House, the companies whose reputations were  secured through their association with the building, and the innovative  technologies and methodologies developed to meet the demands of its  unprecedented design and challenging construction. Extending outwards,  these narratives are closely intertwined with Sydney's social fabric;  the workers who built the Opera House, the politicians, architects and  members of the public who championed it and its often beleaguered  architect — and those who found its design simply incomprehensible and  its foreign architect just too unorthodox.
Even before construction started in 1959 the Opera House had directly or  indirectly affected the lives and careers of a number of individual  players. Utzon's life, of course, would be changed forever. It is  unlikely H Ingham Ashworth would be remembered today for anything but  his modest achievements as an academic if it were not for his role as  chairman of the competition jury and, later, his long-term chairmanship  of the Opera House Technical Advisory Panel. And Hungarian-born George  Molnar, one of Sydney's most incisive and gifted cartoonists, literally  cut his cartoonist teeth on the political and design issues surrounding  the competition for an opera house in the mid 1950s. For Robert Geddes,  one of the team of seven 
American architects placed second in the competition — and a  contributing author to this book — the opera house competition provided  an early career opportunity to test collaborative working ideals he  continues to advocate to this day.
In the late 1950s and early 1960s, as the curves of the Opera House  shells were drawn and redrawn and as construction got underway, young  engineers like Jack Zunz, John Nutt and Peter Rice of Ove Arup &  Partners, and Corbet Gore of the building contractor M R Hornibrook,  were inducted into new areas of intensive technical investigation and  testing that subsequently shaped the direction of their careers.  Hornibrook's David Evans, barely finished his engineering degree,  virtually taught himself how to write computer programs on the Opera  House job and went on to work in America with Doug Engelbart, inventor  of the computer mouse. Arup's Michael Elphick and Hornibrook's Ron  Bergin started on the surveying team, found their mathematical skills  were indispensable, and went on to pursue highly successful careers in  information technology and engineering. 
Nick Karantzis, newly arrived from Greece, started as a rigger on the  Opera House and ended up as deputy stage manager in the 1980s. For  Hornibrook project superintendent Bob Wood, the Opera House building  site was a family affair; he and four of his five children worked on the  site in varying capacities during the 1960s. It was to Bob Wood that  Utzon memorably inscribed a section of timber, promising not to conceal  the concrete surfaces that he, Utzon, insisted be perfectly finished.  And it was Bob Wood whose beloved Mini-Cooper was spectacularly hoisted  by crane above the untiled Opera House shells in 1966 as a worker prank  (see p 124). 
Now legendary as a pioneering unionist and community activist, Jack  Mundey began work on the Opera House in 1959 as a scaffolder for Civil  & Civic, the contractor for Stage 1 of the building. In 1972, as New  South Wales secretary of the Builders' Labourers Federation, he  initiated the 'green bans' that prevented the destruction of trees in  the Botanic Gardens for the excavation of the Opera House car park. The  stories of those who laboured on site at Bennelong Point, set against  the background of union activism that defined Australian labour history  in the 1960s, is a compelling chapter in the Opera House narrative.
While association with the building of the Opera House was for many a  memorable and life-defining experience, for some the negative impact of  their association adversely affected the remainder of their careers. For  architect Peter Hall, the controversy over his willingness to take the  reins as design architect after Utzon's 'resignation' in 1966 dogged him  for the rest of his life. And it is unlikely politician Davis Hughes  will be remembered for much else other than his reprehensible  activities, as State Liberal Party Minister for Public Works, to  discredit Utzon in the mid 1960s. The friction that Utzon's departure  created, particularly in the architectural community, is a stirring  story, one that is closely intertwined with the radical social and  political changes that were polarising Australian society, indeed most  Western societies, at the time. For many involved in the protest to  reinstate Utzon back in 1966 — Elias Duek-Cohen, Bill Wheatland, Ted  Mack and many others — the passions the issue provoked are still very  much alive today.
The ripple effect of the Opera House extended well beyond the lives and  careers of individuals; involvement in the project also helped shape or  consolidate the international reputations of a number of companies. The  Danish engineer Ove Arup sought Utzon out within days of the  announcement of the winning entry early in 1957. Subsequently appointed  consulting structural engineers on the project, Ove Arup & Partners  were major players throughout the three phases of construction from 1959  to opening in 1973. Operating initially from its London office, the  company opened a Sydney branch in 1963 in response to the complex  construction demands of the Opera House. The pioneering work on the  Opera House with prefabricated concrete construction methods, with the  application of computer technology to the solution of complex  engineering problems, and the company 'modus operandi', set by Ove Arup  himself, of collaborating creatively with architects, established the  company as one of the world’s leading engineering firms. Today the firm  is engaged on the Opera House upgrade project, once more working  creatively with Utzon in Denmark and local architect Richard Johnson on  refurbishment projects as well as a strategy for the building's  long-term maintenance and use.
M R Hornibrook, the Queensland-based civil engineering company, won the  contract to build Stages 2 and 3 of the Opera House from 1962. With a  prior reputation for concrete bridge construction, the building  technologies the company developed and the knowledge it acquired on the  project laid the groundwork for Hornibrook to become one of Australia’s  largest and most prominent construction companies in the 1970s and  1980s. Steensen & Varming, the mechanical services contractors for  Stage 3, and Höganäs, the Swedish company that supplied the one million  special tiles required to roof the building, have similar, although  perhaps more modest, success stories to tell. To this day Höganäs  continues to manufacture the tile, marketed affectionately as the  'Sydney' tile, for a range of public and domestic purposes. 
On a different front, the association of the pioneering Sydney plywood  company Ralph Symonds with the Opera House was one of thwarted potential  rather than collaboration fulfilled. Realising the possibilities for  the use of his unique giant sheets of plywood in the building early on,  Ralph Symonds, the entrepreneurial head of the company, visited Utzon in  Denmark. The potentially productive relationship thus initiated with  the company — and the extraordinary interiors that its plywood could  have made possible — were casualties of the political interference that  led to Utzon's departure early in 1966.
Finally, the Opera House construction 'story', from beginning to end, is  a story of pioneering technology, of finding creative new solutions to  the many design, technical and construction problems that the building's  unprecedented shape generated. Today, computer modelling inspires and  facilitates the kind of non-linear, free-form architecture that Utzon  could only have dreamt of. It is hard to believe that when Arup's  engineers started devising computer programs to analyse Utzon's first  free-form roof structure scheme in 1958 the electronic computer, as we  know it today, was only 10 years old and so bulky that it occupied a  whole room. Computers were again used when Utzon's final spherical  geometry solution for the roof in 1961 facilitated the erection of the  shells from precast concrete components. Cast in an on-site 'factory',  the repetitive rib segments were then literally joined in the air, an  unprecedented operation that required precise mathematical computer  calculations and which initiated other technological innovations and  'firsts' — the ingenious telescoping erection arch devised to avoid the  need for obstructive scaffolding, the first large-scale application in  the construction industry of epoxy resin to bond the concrete rib  segments together, and the use of the largest cranes in the world to  manoeuvre the concrete segments into place. Many of the innovations  introduced in the building of the Opera House have since passed into  accepted engineering practice.
Building a masterpiece set itself the task of exploring  previously little-documented aspects of the multi-layered history of the  Sydney Opera House, but there are still many stories to tell — of the  architects, like Richard Leplastrier, Peter Myers, Bill Wheatland and  Yuzo Mikami, whose lives were changed after working with Utzon; of the  photographers like Max Dupain, for whom the building became an  obsession; of the filmmakers like Dahl and Geoffrey Collings and John  Weiley, whose important documentaries of the late 1960s are barely known  today. At the heart of all the narratives, however, is still the  magnificent building on Bennelong Point, and its architect Jørn Utzon —  now in his late eighties — who will never stand in the Sydney sunshine  and marvel at the extraordinary presence of his completed Opera House.  Fifty years ago in his quiet studio in wintry Denmark, Utzon could not  have imagined the extraordinary journey on which his competition design  would take not only him, but so many others. Nor could he have imagined  the enduring impact of his creation on the heartbeat of a city — nor  indeed, of a nation.
