Special Feature 專 題 介 紹 The Award Winners The JSD awards for 2008 were given to The Hong Kong Science Park, Phase 2, MGM Grand, Macau and Mega Box. For this article we are focusing on two of these structures, the Science Park and the MGM project. The structures are innovative and contain unique features. The architectural style of each, boldly targets a specific clientele and in so doing provides us with striking structural contrasts. The style of the former is exciting with its golden eggauditorium, and its focus on the management of natural beauty, environmental concerns and waste management. It invites the participation of the cerebral customer by providing an organised, refreshing and stimulating environment. The style of the latter is raunchier and exudes vitality, energy and provokes the imagination, concerning what might bein terms of entertainment and maybe indulgence. However, our particular interest in these two structures is stimulated by the fact that Faculty alumni, Ir Mr Wallace W.Y. Cham, (the Science Park Project), Ir Mr Wilson Y.S. Cheung (the MGM Project) and Professor S.L. Chan (CSE) took leading roles in the development of these structures, hence presenting us with pleasing evidence of the synergy which exists between the Faculty, our alumni and the construction industry. Since the days of the establishment of the Trade School in 1939, the building industry has moved hand in hand with the needs of Hong Kong people and developed in line with the economic, social and political conditions. Looking at Hong Kong now, it is difficult to believe that as short a time ago as the late 1940s, and early fifties tallbuildings were around seven or eight storeys in height, and the construction in 1960 of a twenty storey building at North Point was news. Air conditioning existed only in the Hong Kong Bank, and no flyovers existed until 1963. A question often repeated by alumni of the sixties and seventies is, I wonder what we would have achieved if we had the opportunities of the Faculty students of today? This question can never be answered with any degree of certainty, but it draws attention to the perceived better facilities, equipment, technology, international communications, materials, management methods, advances in the use of information technology and the greater social political and economic stability evident today. All have led to the development of the industry. The justified proud claim of one engineer in 1955, that wheel barrows rather than shoulder poles were used for carrying materials on the Alexandra House site, is today well overshadowed by the presence of the assortment of sophisticated equipment and plants on sites. Likewise calculations by slide rule and calculator are well overshadowed by the power of advanced construction software now available to engineers. Contributory to positive value changes in the construction industry are changes in attitudes and cultures. Management systems have been designed to improve site safety and new technology while ordinances have been introduced to control noise and protect the environment in the face of global warming and climate change. The focus continues to be, on the development of ways to reduce energy wastage in buildings. Further contributions to change are provided by advancement in teaching methods, a broadening of curriculums, and widening of research areas in line with societal and professional expectations, a stronger relationship between the industry and the work of academia to expose areas of clear cut mutual benefit. The Growth of Information Technology A prominent promoter of change, is the dramatic growth in information technology usage. In the 60s, batch processing was the mode of computer utilization. Within the FCLU, the Civil and Structural Engineering Department was the first to have a 4k Wang mini computer system, followed soon after by Hewlett Packard desktops. Computer growth in Information Technology was first seen nationally in the 60s and 70s, in the use of Computer Aided Design(CAD) for the production of drawings, calculation programs such as fluid flow and structural analyses, calculations for bills of quantities and also the development of critical path analysis systems, such as the now commonly used Primavera software. 獎 項 得 主 200708 Mega Box ()1937 1960 1963 -- 1955 資 訊 科 技 發 展 4k (CAD) (Primavera) 40 02

Special Feature 專 題 介 紹 Now, less than 40 years later, the concept of performance based design has entered the construction industry and represents a major philosophical shift from the traditional rule based or prescriptive formula design. The introduction of this concept takes advantage of the powerful software modeling systems which have recently emerged and which are now being adopted by the more adventurous, pioneering practitioners. Software, in this category, includes computational fluid dynamics for modeling the spread of fire and smoke. Computer systems for air conditioning control are another type of software available. The systems are linked to sensors and intelligently interpret information to optimize the use of energy, but keep within the required comfort parameters of the user. 資 訊 科 技 及 得 獎 項 目 (NIDA) NIDA2000 Detailed graphical models are also being used as central to the whole project information systems. Some of these models enable the actual construction sequences to be simulated and displayed on the computer screen in fine realistic detail. The obvious effect of this is to enable the identification, in advance, possible site problems, hence enhancing construction speed and reducing wastage on all fronts. IT and The Winning Projects To return to our theme and interest in the two 2008 JSD awards, the Science Park and the MGM project, we must draw attention to the contribution of Professor S.L. Chan, to these structures. He developed a software package Nonlinear Integrated Design and Analysis (NIDA) to enable advanced structural analysis for predicting failure beyond the usual elastic range, and extending to the stresses and deformations which occur up to the point of structural collapse. The software was launched in 2000 and is the first of its kind in Hong Kong. It makes faster, safer innovative design possible. It has now been used in many real cases by pioneering practitioners. Examples include, the Singapore International School, the glass wall of West Kowloon station, the Birds Nest in Beijing. The two JSD award winners amply illustrate the benefits accrued from the use of such software, as opposed to the traditional use of prescriptive formula. Not only does the NIDA software enable the aesthetics of a building to be realized in the form of a slimmer and lighter appearance, it also enables the creation of a building, which at one time would have been thought not structurally possible. NIDA also enables a more economical use of design time, materials and space. In the Science Park, dramatic examples are provided by the ability of the new technology to create areas with an atmosphere of unfettered space, such as the sweeping contours of the amphitheatre . These innovative structures are not only exciting to view but also fulfill their functional promise. Both designs made use of NIDA. JSDNIDA NIDA 60 The American company MGM wanted to bring to Macau the feeling of Las Vegas, with its sense of extravagance and land mark constructions. Again, the NIDA software package was used and as for the Science Park, S.L. Chan worked with the project teams, throughout the duration of the project, contributing to the delivery of the unique constructions the company had in mind. Visitors to Macau are provided with the unforgettable spectacle of the extremely slender and unique wave frontage of the hotel tower as well as the startling 60 metre wide, glass roofed conservatory, without any central columns in sight. 03

<strong>The</strong> Award Winners<br />

<strong>The</strong> JSD awards for <strong>2008</strong> were given to <strong>The</strong> <strong>Hong</strong> <strong>Kong</strong> Science Park,<br />

Phase 2, MGM Grand, Macau and Mega Box. For this article we are<br />

focusing on two of these structures, the Science Park and the MGM project.<br />

<strong>The</strong> structures are innovative and contain unique features. <strong>The</strong> architectural<br />

style of each, boldly targets a specific clientele and in so doing provides<br />

us with striking structural contrasts. <strong>The</strong> style of the former is exciting with<br />

its golden eggauditorium, and its focus on the management of natural<br />

beauty, environmental concerns and waste management. It invites the<br />

participation of the cerebral customer by providing an organised, refreshing<br />

and stimulating environment. <strong>The</strong> style of the latter is raunchier and exudes<br />

vitality, energy and provokes the imagination, concerning what might bein<br />
