Special Feature 專題介紹 Special Features of the Award Winning Projects As mentioned above, alumni, Wallace Cham, Wilson Cheung and Professor SL Chan all generously gave their time to discuss these award winning projects, and draw attention to features of interest. Their enthusiasm and dedication was palpable. Polyu alumnus, Wallace Cham who added an MSc in 2007 to his many other qualifications, was a member of the project team for the Hong Kong Science Park Phase 2, being the Senior Manager of Projects for that corporation. 得獎項目簡介 2007 () 1) The Science Park Phase II 科學園二期 The Science Park Phase 2 is a complete unit, following the completion of Phase 1 and preceding the future extension into Phase 3. The market role of the park is unique and pioneering in Hong Kong. Its aim is to create an area which provides every conceivable means to encourage and enable innovation and research and development (R&D) activities for high tech and high value industries, such as electronic, precision engineering, IT/telecommunications and biotechnology. The Phase 2 buildings are already more than 30% occupied with further clients ready and waiting. Wallace and his team found great satisfaction from the fact that not only were they contributing to providing a means to educate the next generation, they were also contributing to the enhancement of the reputation of Hong Kong, not only in terms of technological recognition but also in the provision of a truly beautiful place which marries natural and technological beauty. solution to satisfying structural stability, architectural and acoustic requirements. The supporting inclined columns (labeled crazy columns) and ring beams, effectively combine to distribute, by arching action, both gravity and lateral loads. / One reason, given by Wallace for the Science Park project reaching such a satisfactory conclusion is the harmonious and unstinting cooperation of all parties involved. Valuable briefing meetings were conducted before the designs were finally decided and operations commenced. Common to all parties involved in the project, was the aim for sustainable development and environmental friendliness. Such philosophies, in the face of climate change, are now beginning to underpin the more enlightened construction activities world wide. Among others, contributions to sustainability were made by the introduction of a waffle floor system, whereby the high degree of repetition promoted the use of system formwork. In addition, precast formwork for pile caps and tie beams was used, thus saving timber. In the area of sustainability, Wallace drew particular attention to the 700 metre underground service tunnel and basement linking different buildings throughout the whole Phase 2 area. The majority of the services are housed inside the service tunnels, enabling ease of maintenance and quick-fix of problems. Functionality is also provided by the two energy towers which house the A/C chiller plants and cooling towers for all the Phase 2 buildings.. In this connection, there is no need to provide such plants in individual buildings. Maintenance savings, as well as cost, materials and time savings are obvious results. All who visit or use the Science Park feel that the public have been presented with a structure which has to be experienced from the exterior, interior and as a functional work unit, in order to be fully appreciated. A visit to and participation in events held in the auditorium or amphitheatre enable a fuller appreciation of the design creativity and innovation on display. (PTFE) The design and construction of the amphitheatre, which is a large tension membrane fabricated from architectural grade Polytetrafluoroethylene (PTFE) coated fiberglass fabric is inspiring, being the first amphitheatre covered by a tensile fabric steel structure to be approved by the Hong Kong Government authorities. A unique structure is the oval auditorium, mentioned above and which has become known as the golden egg. The hybrid concrete-steel structure gives an efficient 04
Special Feature 專題介紹 2) The MGM Grand Macau 澳門美高梅金殿 Polyu Alumnus, Wilson Cheung, who graduated in 1992, is at present an Associate Director of Siu Yin Wai and Associates Ltd. He and his team were the structural designers of the JSD award winner, MGM Grand Macau, which from the very beginning they were confident would be a success. Particular pride is taken in the speed of construction. Piling work began in June 2005 and the occupation permit was delivered in December 2007. The structure offers the viewer, in terms of beauty and building utilization, a totally different experience from that of the Science Park. Where the latter offers space and tranquility conducive to reflection and academic activity, the MGM Grand, with its gleaming golden façade and voluptuous wave frontage shouts an invitation to the bold and the adventurous. The appearance and layout of the former stimulates curiosity and reflection, the latter stimulates the search for more physical, even hedonistic pleasures. The MGM Grand, Macau is a casino and hotel project bound by the Avenidas Dr Sun Yat- Sen, 24 De Junho and the Rua Cidade De Porto. A waterfront view calms the senses and is in contrast to the opulence of the building. The contract sum was over 4 billion. One of the most exceptional considerations of this project is the wind + seismic deflection requirement of the hotel tower. The Macau wind code is based on 200 years return period which is nearly 50% higher than the Hong Kong code. The hotel tower is exceptionally slim, 150 metres high with an aspect ratio of approximately 9. To deal with these unique criteria, wind tunnel testing was adopted to find the wind load of the tower structure. The result is an enhanced core wall and shear wall to resist these high lateral pressures. The MGM project consists of four levels of podium, which house the casino, gaming areas, shops, restaurant, theatre, a conservatory for casual meetings, a basement level car-park and at the front, a 35 storey hotel tower. The pleasure which can be gained from what is seen or anticipated is in part due to the skills of those like Wilson Leung and the construction teams. The visitor can admire and wonder at the unique appearance of the hotel towers design, with its three layers of rolling waves, every crest in contradiction with those crests, above and below. One tower layer is yellow gold, the second, white gold and the third, rose gold. Other memorable features include the glass and steel elliptical canopy of the main entrance, measuring 26x60 metres, the 56x60 light weight glass roof over the conservatory, both designed to enable these areas to be flooded with whatever light effects nature can provide. The conservatory, which provides a grand and imposing transition area for those passing from the hotel to the casino, provides what appears to be limitless space, without any central columns in sight. The clear span of the space frame is about 60 metres, which is a similar size to a 20 storey building laid horizontally A large curved steel frame supporting the largest LED display in Macau is found at the North East entrance. 1992Associate Director 20056200712 200 1509 35 26x60 56x60 60 20 05
