MESSAGE Message from the IES President The Four th Industrial Revolution, which includes developments in previously ‘disjointed’ fields such as ar tificial intelligence and machine-learning, robotics, nanotechnology, 3-D printing, and genetics and biotechnology, is expected to cause widespread disruption not only to business models but also to labour markets over the next five years, with skill sets having to change, to succeed in the new environment. This is the finding of the report ‘The Future of Jobs’, published by the World Economic Forum in January, this year.

There will also be a widening of the employment gender gap, with women losing five jobs for every job gained compared with men losing three jobs for every job gained.

In dealing with these changes, the most popular workforce strategy across every industry is investing in reskilling current employees. Other practices, such as suppor ting mobility and job rotation, attracting female and foreign talent and offering apprenticeships, also scored high. Hiring more shor t-term or vir tual workers are much less popular responses.

Against these somewhat ‘unsettling’ findings, the repor t predicts some positive trends, closer to home.

ASEAN, GCC and Japan will have only 25% skills instability which is lower than in other par ts of the world. Also, the highest ratios of jobs created per job lost is expected to be in ASEAN with 3.72 jobs gained per job lost.

The survey respondents also expect strong employment growth across the Architecture and Engineering and Computer and Mathematical job families, a moderate decline in Manufacturing and Production roles and a significant decline in office and administrative roles. Other sizeable job families, such as Business and Financial Operations, Sales and Related, and Construction and Extraction have a largely flat global employment outlook over the 2015-2020 period.

THE SINGAPORE ENGINEER June 2016

INTERVIEW

Revitalising the profession to serve community and country Rapid technological developments have resulted in significant changes in the definition of engineering and the role of engineers. Er. Edwin Khew, the newly elected IES President, outlines the strategic direction for the institution, in order to ensure that engineering regains its importance as a career of choice.

Er. Edwin Khew

The Singapore Engineer: Many congratulations on your elevation to the position of President of IES. It comes at a time of great challenges and perhaps of great opportunities, as well. There is also added significance since IES is celebrating its Golden Jubilee this year, which follows the celebration of Singapore’s 50th year of independence, in 2015.

What are your thoughts on Singapore and IES crossing these important milestones?

Er. Edwin Khew: The last 50 years have seen engineering losing its prominence as one of the most desirable career choices in Singapore.

We are faced with the challenge of ensuring there are enough engineers to fulfill the huge demand in many industrial sectors to support our growth as a high-tech nation. As the President of the national society of engineers, I will have to steer IES in

04

playing our role in addressing this issue, just like the IES Presidents in the last 10 to 15 fifteen years have had to do.

On the brighter side, Singapore has made significant achievements in terms of innovation, technology development and engineering, over the last five decades. Today, Singapore is the water hub of the world, a leader in many areas of R&D and a manufacturer of many high-tech components and systems including pharmaceuticals, medtech robots and oil drilling rigs. I would say that Singapore is at the threshold of greater inventions and innovations and becoming a leader in other fields and sectors, besides water. We stand at the cusp of an exciting future for Singapore, for engineering and for IES. I am honoured to be the President during the Jubilee Year, to steer IES towards greater progress in the next 50 years.

Q: The Government has pointed out that as the country undergoes economic transformation, there will be an increasing need to match the skills of the workforce with the jobs that are created. What changes do you see taking place, within the engineering sector, especially with the increasing importance of the newer ‘disruptive’ technologies? What role could IES play in addressing these developments?

A: Change is something we can count on as par t of Singapore’s

THE SINGAPORE ENGINEER June 2016

transformation because of changes taking place in new and exciting disruptive technologies. The engineering sector will also have to evolve to manage these new technologies including additive manufacturing, robotics, new composite materials, AI (artificial intelligence) machines and autonomous vehicles. To be relevant, IES and its various technical committees (TCs) will have to keep abreast and even ahead of these new developments. Only then can IES be the engineering voice for these new technologies, in harnessing them for Singapore’s economic growth and in training engineers to use these technologies to Singapore’s advantage.

Q: On 22 April, this year, 175 parties signed the historic Paris climate accord. Climate change and the need to achieve sustainability is a subject that is very close to you. How can engineers, in general, and IES, in particular, contribute to attaining this objective?

A: Mitigation of the effects of climate change is a collective effor t, making the COP 21 held in Paris a significant move, as more than 130 countries signed the climate change agreement in New York on 22 April 2016. IES will continue to play its part to promote the mitigation of the effects of climate change through engineering. We will continue to organise the World Engineering Summit bi-annually and the leaders’ roundtable annually, to facilitate impor tant discussions on various aspects of climate change,

INTERVIEW from mitigation and adaptation to increasing the climate resilience of urban cities.

Q: What do you think about the Government’s recent initiatives to improve the attractiveness of public-sector engineering jobs (eg better salaries and career development opportunities)?

A: The Singapore Government’s initiative to raise salaries of engineers is a major step in demonstrating to our young the vital role being attached to engineering in Singapore’s future economic growth. I do hope that the private sector will follow suit so as to raise the importance and relevance of engineering as a career to where it should be. Engineering, in my opinion, is as critical a profession as medicine and law, in realising a matured and growing economy.

Q: How can IES ride on this wave to help the engineering community be better recognised for its efforts?

A: IES has organised the Engineering Feats @ IES-SG50 competition to engage the public in recognising the contribution of engineers to Singapore’s past 50 years’ of development. Through the competition, the public have had a chance to vote for engineering feats which have affected their lives and helped the Singapore economy over the last 50 years.

IES will also continue to partner the Science Centre Singapore (SCS) and other private and public sector organisations and NGOs to promote engineering in schools, polytechnics, and IHLs. We will continue to hold activities such as the annual National Engineers Day (NED), engineering displays at SCS, engineering career talks, STEM competitions and those promoting hobbies related to science and engineering in schools. Our goal is to see the public and our younger generation embrace engineering as a key contributor to their quality of

life and the economic well-being of Singapore into the future.

Q: What are some of the other major challenges for the engineering profession and for engineers, and how can IES assist?

A: I see several major challenges related to the engineering profession: Firstly, we need to raise the value of engineers and their corresponding remuneration.

Secondly, we need to be more effective in attracting the younger generation to take up engineering as a course of study in our universities, polytechnics and ITEs. Currently, engineering courses are perceived to be difficult to excel in, compared to other courses like social sciences, business administration and commerce. Many students choose these other courses because of shor ter course duration and yet offering equivalent remuneration to that for engineering graduates.

Thirdly, we need to provide for an exciting and interesting career pathway for engineers to keep them in engineering.

To address some of the above issues, IES has developed par tnerships with the NTUC to provide leadership training for young engineers and advanced leadership training for senior engineers to assist them to advance in their careers in technical or management roles. IES will also be looking at training technicians to equip them with skill-sets to be master craftsmen capable of servicing and maintaining machines, automated systems and robots and to increase Singapore’s industrial productivity.

Q: What are the key organisational initiatives that you would be spearheading, during your tenure as President, that would enable IES to represent, with greater effectiveness, larger numbers and more diverse groups of engineers?

Top three priorities for IES Membership growth To be more inclusive and to provide value and relevance to members Promoting engineering as the profession of choice To enhance IES’ brand and image IES as the preferred partner To become the focal and reference point for all engineeringrelated matters.

A: In line with the three priorities outlined above, as President, I will develop a road map with my six VPs, as proposed by the in-coming Council members at the Away Day retreat held in May. In addition, I will also focus on the softer aspects of engineering - to promote greater environmental consciousness and healthy living amongst our members. For example, I will be looking at organising weekend cycling trips from IES to the nearby Rifle Range road and even off-track cycling on our old railway track route from there. I also hope that our members will be more enterprising and that IES will develop more young engineering technopreneurs through the Enterprise Development Committee.

I also aim to encourage our members to be more socially responsible by volunteering to help the less fortunate and the disabled through the community service outreach committee. I believe that as engineers, our members can offer their engineering knowledge as practical advice to help people address issues they face in their homes to enhance their quality of life.

INTERVIEW

Q: What is your vision for IES100? What do you hope we will become in the next 50 years?

A: It is difficult to imagine what the world will be like, 50 years from now, but I reckon that technology will play a big role, based on today’s rapid technological developments. We are already talking about technologies such as the Internet of Things, autonomous vehicles and robots with artificial intelligence. So what we see in science fiction movies will become a reality. This means that future engineers will be different from the engineers of today as they will have to design, operate and maintain very complex systems. There might not be pure civil, electrical or mechanical engineers anymore but engineers who are totally integrated, trained in all disciplines of engineering to solve multifaceted, multi-disciplinary problems through smar t machines, computers and tools.

IES UPDATE The following three stories/interviews were first published in the IES 50th Anniversary Gala Dinner Souvenir Magazine.

Tribute to Er. Kenneth Gin, Founding IES President IES’ illustrious 50-year journey began with one of Singapore’s most eminent pioneer engineers: Er. Kenneth Y D Gin

Er. Gin, first President of IES (1966/1968)

On its 50th anniversary, IES journeys back in time with its founding President, Er. Kenneth Gin, a man whose pioneering work had not only laid down enabling roots for the growth of a stellar institution, but shaped Singapore’s early years of nation-building through civil engineering excellence.

Er. Gin’s became the founding president of IES at its historic inaugural meeting held at the Public Works Department Sports Club at Kallang on 1 July 1966. Aided by his steadfast stewardship in its early years and his longstanding contributions in the succeeding decades, IES grew in stature as the premier engineering institution in Singapore.

12

Er. Gin’s hallmark selflessness and dedication have set high standards for his successors to emulate. As the first President, he tirelessly initiated the setting up of various committees to look into various tasks that would define IES’ future roles.

He also remained actively engaged in the institution’s affairs until the turn of the century, playing a key role in transforming IES from a humble set-up of just 166 engineers to the heart and voice of more than 5,000 members today.

Born in Melbourne, Australia in 1924, Er. Gin moved to Singapore only in 1956, when he married Dr. Wee Kit Gin, a Singaporean medical doctor, out of a romance that blossomed from a fishing trip! The relocation was a difficult decision for Er. Gin, as it meant foregoing a secure job and the prospect of becoming a par tner of a large firm of engineering consultants, Scott & Furphy.

But looking back, Er. Gin has no regrets as his move to Singapore gave him the unique oppor tunity to play a leading role in establishing the basic infrastructure systems of a country that is to become a global economic powerhouse and one of the world’s most livable cities.

Er. Gin’s contributions to Singapore as a civil engineer started in 1956 when he was one of the project engineers for the Merdeka

THE SINGAPORE ENGINEER June 2016

Er. Gin appointed as the general manager of the Public Utilities Board in 1966

IES UPDATE Bridge over the Kallang River - the longest bridge in Singapore measuring 2,000-feet in length and with 80-feet spans. His job involved the manufacturing and erection of the pre-stressed concrete beams for the bridge.

Er. Gin’s career turning point came when he was appointed the deputy director of Public Works, Singapore in 1959. Singapore was going through an exciting phase of infrastructure development then to suppor t its rapidly growing population and expanding economy.

During his seven years at PWD, Er. Gin saw the completion of notewor thy engineering projects including the Paya Lebar airpor t terminal, the iconic Market Street multi-storey carpark, Singapore’s first pedestrian underpass at Connaught Drive; as well as the initial phases of the Pan Island Expressway and the Mass Rapid Transit system.

He continued to make remarkable contributions to Singapore over the next few decades, from public infrastructure to public utilities to building development. During this period, he took on key roles as the general manager of the Public Utilities Board in 1966, group general manager of Singapore Land & Investment in 1970 and the first general manager of the Sentosa Development Corporation in 1973.

“I feel very lucky to be able to contribute to Singapore’s nationbuilding journey. It is a pleasure to have played a small role in helping Singapore transform from a backwater colony to a country with excellent infrastructure,” Er. Gin said humbly.

Looking at his extraordinary achievements, not many people would have guessed that Er. Gin’s engineering career did not start easy. None of his family members,

relatives or friends had a background in engineering back in the 1920s. This meant that he had to find his own way to obtain a Civil Engineering degree at a young age to pursue his passion for mathematics. Upon graduating with an engineering degree from the University of Melbourne in 1945, he also had to wait five tedious months before landing his first job with a consulting engineer, due to the scarcity of jobs in postwar Australia.

remains in Singapore “ There and the world around us, a huge reservoir of work for engineers … Today, we have different opportunities, which require changes in our thinking.

With imagination, initiative and resourcefulness, such opportunities are well within the ambit of the engineers' capabilities.

”– Er. Kenneth Gin

Er. Gin hopes that the younger generation of Singapore will carry the same passion for engineering as Singapore crosses into its second 50 years of development. He believes that Singapore’s future development will hinge on engineers and that the society will have much to benefit from engineers.

“The rapid and successful development of Singapore over the last few decades is due in no small par t to the contributions of engineers. The modern buildings, the new roads and highways, the por t and airpor t developments and the mass rapid transit system are typical examples. Engineers can take pride that they have made very valuable contributions to Singapore's eco-

nomic development,” said Er. Gin. “Moving ahead, there remains in Singapore and the world around us, a huge reservoir of work for engineers, not restricted as in the historic past, to engineering alone. Today, we have different opportunities, which require changes in our thinking. With imagination, initiative and resourcefulness, such opportunities are well within the ambit of the engineers' capabilities,” added Er. Gin. On IES’ golden jubilee celebrations, Er. Gin believes that IES has made huge strides in its role as the hear t and voice of engineers over the last 50 years. He hopes that IES will continue its good work and carry on the legacy laid down by its founders.

To IES, their founding President is not just a link to the past but an inspiration for the newer generation. His values, commitment and courage in steering IES through the unknown in its early years will serve as a driving force in advancing IES towards a brilliant future.

Interview with Er. Dr. Lee Bee Wah, first female President of IES Acting Minister Ng Chee Meng all have engineering degrees. As mentioned earlier, engineers are trained to look at problems holistically, analyse the issues, find solutions, trouble shoot and iron out the kinks – which are essential skills for leaders to have.

Er. Dr. Lee Bee Wah

ABOUT SINGAPORE

1. In your opinion, what are some of Singapore’s greatest achievements in engineering during its first 50 years of growth?

All the infrastructure around us from the transport system, the waterworks, airports and seaports to the reservoirs and dams, you name it - they all involved engineering. So I can’t name just a few.

2.

How has engineering changed our past?

It is estimated that about half our economy relies on engineers. So Singapore’s remarkable success story and indeed world-wide progress to where it is today would not have been possible without engineers.

And you can see the value of engineering not only in infrastructure development but in problem-solving, strategising and analysing. For example, many top leaders in politics and finance were trained as engineers. In our current Cabinet alone, DPM Teo Chee Hean, Minister Khaw Boon Wan, Minister Yaacob Ibrahim, Minister Lim Hng Kiang, Minister Gan Kim Yong, Minister Masagos Zulkifli and

3. How will engineering change our future?

Engineers will play a big part in our move towards a Smart Nation and continue to be essential to our economy. We are moving into higher technology, fintech, drones, audio recognition, cyber security which will change the way we live. Hence, the government is recruiting more engineers and giving them better career paths, so that they will continue to play a big part in our government and the bulk of them will remain in the profession to contribute to our country.

4. Do you see female engineers playing a bigger role in Singapore’s future?

Yes. More women are becoming engineers. I hope women will overcome stereotypes and become the equal of men in the engineering field.

Engineering is not about gender. It’s about your aptitude for the profession; your ability to identify problems; as well as your analytical, communication, decision-making and leadership skills.

ABOUT IES

1. Do you think IES has accomplished its vision as the heart and voice of engineers and the national body and home for engineers in Singapore in the past 50 years?

I am very happy that IES has grown in its role as the voice for engineers in Singapore. IES has grown with our nation. As Singapore develops, the

THE SINGAPORE ENGINEER June 2016

quality, quantity and the need for different disciplines of engineers will expand and rise dramatically. IES must help our nation to achieve this. In the past, IES has done so by improving industry standards, nurturing new fields of engineering, and improving the recognition for engineers. IES has also been encouraging engineers to take an interest in social causes, like caring for the disabled and the environment.

The work of IES has helped to make engineers more visible in Singapore.

2. What do you hope for IES to achieve for Singapore’s future?

As Singapore progresses into the next 50 years, engineers will continue to play a critical role in nation-building not just as professionals in their field of expertise but also in the social and political well-being of our country. I hope IES as a professional body will continue to be the voice for engineers and play a bigger role in the national policies.

3. What are your personal wishes to IES for reaching this milestone?

I hope IES keeps up the good work in all the aspects mentioned and continues to be a key part of Singapore’s success. I also hope that IES continues to engage the government through various platforms so that they can work together for the common goal of putting Singapore on the forefront in economic, infrastructure and technological development.

ABOUT YOURSELF

1. What is the significance of your appointment as the first woman IES president in 2008, and the only woman president in IES’s 50-year history?

It signifies that IES values woman en-

IES UPDATE gineers. Gender is no longer a handicap - women can be good engineers and contribute to society just like the men. I hope there will be another woman president soon!

2. What are some of your proudest contributions during your two-year IES presidency?

Can you recall some of the most uplifting moments?

In the years when I was president, I believe IES was able to raise its profile and become more visible through the media, as well as in Parliament when I raised professional issues. I think today IES is in the good hands of a team of new leaders and it is for them to bring IES to the next level.

3. How did it feel to be the first female president of IES?

I felt very honoured and I hope I have become a role model for women engineers at large. I was also the first Singaporean to be awarded the title of Honorary Fellow of the Institution of Structural Engineers (“IStructE”) in the United Kingdom.

4. What advice would you give to young female students who are considering taking up engineering as a course of study or as a career?

There is a perception that women are not as good in mathematics and science, making them not as good as engineers as men. This has been scientifically proven to be an erroneous perception. If you are interested in engineering, take the plunge. It has been an interesting and rewarding career for me, especially when

I could use my knowledge to help other people in the community.

For example, I use my engineering training to solve problems and to improve the lives and living environment for my residents.

5. What are some things you wish you had done as the IES President but did not get the opportunity to do so?

I always believe in appreciating the moment and doing my level best.

Never look back! So to me, nothing had stopped me from wanting to do what I could have done then. I appreciate the support that I had from my fellow council members, the staff and the general membership. It was a memorable experience to helm IES as its first woman president.

These essentials are sometimes overlooked and taken for granted.

ABOUT SINGAPORE

1. In your opinion, what are some of the biggest contributions that engineering has made to Singapore in its first 50 years of growth?

Though having not experienced it personally, we have learnt of Singa-

2. What would you like to say to the pioneer engineers who have laid the foundation of growth for our nation’s economy, infrastructure and our lives?

I would like to sincerely thank our pioneer engineers for laying down the foundation for us to build upon.

Sir Isaac Newton once said, “If I have seen fur ther, it is by standing upon the shoulders of giants”.

3.

How has engineering changed the lives of people of your generation?

Engineering has improved our quality of life and will continue to do so. Engineering has allowed us to stay connected through physical transpor tation of people and goods, information exchange, and mobility across countries and economies. This has opened up plenty of oppor tunities for our generation.

4. What do you think are the greatest opportunities for young engineers in Singapore?

Great oppor tunities can be found in the civil infrastructure sector that is being expanded in Singapore, such as the air, sea and land transpor t sectors. For example, the eastern par t of Singapore - Changi

Additionally, smar t nation initiatives have given rise to opportunities to enhance the “software” aspect of the “hardware” or the physical infrastructure that has largely been formed. There is much room for creativity and to explore ways of making better use of what is available to us.

ABOUT IES

5. Do you think that IES has played a significant role in Singapore’s past engineering achievements?

IES plays a crucial role in fostering and maintaining the community spirit of engineers in Singapore. It is a place where engineers can gather and share ideas on an equal and neutral platform and with respect for each other as engineers. It is impor tant for IES to continue to bring engineers from various sectors and background together to discuss ideas and in doing so, contributed to Singapore’s past engineering achievements.

6. Do you think IES is keeping up its relevance for the younger generation of engineers?

Personally, I see that IES is adapting to the changes and needs of the younger generation. IES works with various par tner agencies, in both private and public sectors, on many initiatives to enthuse and attract the young into the field of engineering by conducting seminars, forums, technical visits and programmes.

The launch of our Young Engineers Leadership Programme, jointly organised with NTUC, is one such example.

ABOUT HIM 7. How do you hope to make Singapore’s future better as an engineer?

I believe that engineering is not about a job working in silo. Through IES, I hope to be exposed to diverse engineering knowledge and ideas, meet like-minded engineers at conducive networking platforms and applying the multi-disciplinary knowledge acquired to enhance the engineering work that I do.

8. What motivated you to join IES? Why should young engineers do the same?

As the national society of engineers in Singapore, IES is naturally one of the best places where one can network and interact with fellow like-minded engineers and have opportunities to learn from the senior members in IES who possess a wealth of experience. Another great way to learn is to serve in the committees that work together on the various initiatives carried out in IES. 9. In what ways do you think you have contributed to IES as the Young Engineers’ Committee Chairman? What do you aim to achieve moving forth?

I guess one of my biggest contributions is lowering the average age of the membership profile in IES! On a more serious note, I hope to encourage more fellow young engineers to join IES through its various initiatives and activities, give a little of our time and energy to add to the good work of IES, tap upon the experience to grow in our personal careers and ultimately contribute to the society-atlarge in various areas of engineering.

IES UPDATE

IES Publication History Over the years, IES has made use of many platforms to communicate with and encourage participation from the membership base. In the final instalment of our six-part series on IES’ history, The Singapore Engineer looks at the how IES publications have changed over the years. ca. 1972 – 1983

The “Bulletin of The Institution of Engineers, Singapore” can be considered the mother of all publications – it contained technical articles, as well as membership reports and institution news.

ca. 1997 – 2000

ca. 1960s – 1990s

IES UPDATE

The list of members, as well as the President’s Report for the year, were consolidated in the IES Year Book. The first book was produced for Council Session 1972/1973.

As IES grew in membership, it was only logical to have its list of members as a standalone publication. This became the IES Engineering Directory, which has lasted to the present.

ca. 1995 – 2009

ca. 2006 – 2008

2010 – present

ca. 2008 – 2012

The Singapore Engineer had its beginnings in the late 90s as IES sought to provide a platform to advertise events and to report on those that have already occurred. As IES grew, the volume of editorial coverage increased, and the inaugural issue of TSE as a magazine was delivered in May 2000 (second from left).

The masthead evolved over the years to become the one ever y member is familiar with today.

Technical articles were consolidated into the IES Journal, which focused on different disciplines in each issue, published quarterly. In 2008, IES partnered with international journal publisher Taylor & Francis to produce The IES Journal Part A: Civil & Structural Engineering. This journal had a print run of eight years, until the contract expired in 2015.

Other publications

The IES Annual Repor t (2008/2009 edition pictured), which summarises the accomplishments of each council session and the financial health of IES, has existed as a separate publication since the early 2000s. In our effor t to go ‘green’, a greater emphasis has been placed on delivering it through the Internet, saving on paper consumption.

20

To recognise the achievement of engineers and to showcase them as role models for the young, special publications such as “Who’s Who In Engineering Singapore” were produced. Two editions were published in 2007 and 2013, containing the profiles of many eminent engineers of the time.

IES has also produced special publications related to the flagship events we have hosted, such

Last but not least, as a physical record of our storied histor y, IES has come up with commemorative magazines for impor tant celebrations such as the IES Annual Dinner (2015 edition pictured), and milestones such as the official opening of the IES Green Building @ Bukit Tinggi.

COVER STORY

Recognising Engineering Excellence The Singapore winners of the ASEAN Outstanding Engineering Achievement Award represent the constantly increasing capabilities of the republic’s engineers, as well as the vision of organisations implementing these highly acclaimed projects.

The Institution of Engineers, Singapore (IES) is celebrating its Golden Jubilee which significantly, follows closely after Singapore’s 50th year of independence.

It would be fitting, at this point, to try and record the nation’s engineering achievements and the contributions of engineers in the design, execution and operation of these projects. However, this is a daunting task as there are innumerable small, medium and large projects, implemented by public and private sector organisations, and by academic and research institutions, as well as the work of individuals, all of which, have played and are playing an impor tant role in the economic and social development of the country.

On its part, IES has been giving recognition to engineering achievements in Singapore, through the IES Prestigious Engineering Achievement Awards, which are presented every year.

COVER STORY Project: SARS-Combating Innovations: IFSS & C-T&T

Organisations: Defence Science & Technology Agency, ST Electronics and Chartered Electro-optics The joint team of engineers from the Defence Science & Technology Agency, ST Electronics and Chartered Electro-optics was honoured for harnessing technology innovatively to develop solutions that contributed to Singapore’s fight against SARS. The award was given for two innovations - the Infra-red Fever Screening System (IFSS) and the Contact Track & Trace System (C-T&T).

The Infra-red Fever Screening System enables large groups of people to be screened for SARS efficiently, effectively and nonintrusively at the air, land and sea checkpoints in Singapore. It generated world-wide interest and at the height of the SARS outbreak, it was deployed at Toronto, Hong Kong, Beijing, Taipei and other cities. The system thus helped to curb crossborder spread of SARS. The Contact Track & Trace System records the movement of staff, patients and visitors at hospitals. In the event of a suspected SARS outbreak, it provides a speedy and reliable means for contact tracing. All relevant information of the contacts will be available at the touch of a computer button.

The two innovations have several common attributes.

• Both represent first-ever innovative uses of relevant dual-use technologies for purpose-built solutions to contain the spreading of disease.

Both innovations provided timely, user-friendly and public-friendly solutions that overcame the shortcomings of existing alternatives.

• The innovations were conceptualised, developed, tested and operationalised within a week.The results demonstrated the resourcefulness, teamwork and commitment of the engineers involved.

• Both innovations showcased the collaborative spirit of various government agencies and private companies, and their ability to respond quickly to a national crisis.

• Both attracted extensive media coverage and contributed towards boosting public confidence and enhancing Singapore’s reputation as a responsible country.

Project: Bioscrubbers - A Cost Effective and Environmentally Friendly Alternative to Chemical Scrubbers

Organisation: Aromatrix Technologies Pte Ltd AroBIOS is a biological process technology for the control of odorous gases, particularly from municipal waste water treatment facilities. Unlike conventional gas scrubbers, the AroBIOS technology does not require the use and storage of chemicals, making it a more environmentally friendly odour control method.

The AroBIOS process has been proven and tested at several wastewater treatment plants worldwide.

Project: Deep Tunnel Sewerage System

Organisation: PUB Singapore The Deep Tunnel Sewerage System (DTSS) project is an innovative and cost-effective solution to meet Singapore’s long-term needs for used water collection, treatment and dis-

posal. It is conceptualised as a means to relieve land use in land-scarce Singapore and also to convey and treat used water reliably.

The first phase of DTSS was completed in 2008, and consists of a pan-island deep tunnel sewer and a network of link sewers to convey used water by gravity to a large water reclamation plant (WRP) at Changi for treatment.

The treated effluent is then discharged through a deep-sea outfall, or further purified to produce NEWater (highgrade reclaimed water).

PUB is now extending the system to cover the western part of Singapore under Phase 2 of the DTSS, which is expected to be completed by 2025.

When fully completed, the DTSS will streamline the used water network with three centralised collection and treatment points: Changi WRP in the east, Kranji WRP in the north and Tuas WRP in the west. This will free up prime land used by the existing plants and pumping stations, as well as the buffer zones surrounding the plants, shrinking the land occupied by used water infrastructure by 50%.

In the long run, due to economies of scale, it becomes more cost-effective to implement DTSS than to continue to upgrade and expand existing plants.

The DTSS forms an integral part of the water loop, allowing PUB to channel used water to WRPs and then on to NEWater factories where high grade reclaimed water is produced thus securing a sustainable source of water supply for Singapore.

Project: Marina Barrage

Organisation: PUB Singapore Marina Barrage is a dam built across the Marina Channel, creating Singapore’s first reservoir in the city. The 15th reservoir, Marina Reservoir, has the largest and most urbanised catchment, at 10,000 hectares.

THE SINGAPORE ENGINEER June 2016

Marina Barrage is the result of former Prime Minister Mr Lee Kuan Yew’s vision of a freshwater reservoir, created by damming the mouth of the Marina Channel.

The barrage, which comprises a series of nine crest gates, is built across the 350 m wide Marina Channel to keep out seawater. With the barrage in place, the Marina Basin has been turned into a body of freshwater through natural flushing over a period of time. The freshwater is treated using advanced membrane technologies to ensure that it is safe for drinking.

Water from local catchment is one of Singapore’s Four National Taps, with the other three being imported water, NEWater and desalinated water.

Marina Barrage is also part of a comprehensive flood control scheme to alleviate flooding in the low-lying areas in the city, such as Chinatown, Boat Quay, Jalan Besar and Geylang.

The barrage separates the reservoir from the sea. During heavy rain, the steel gates are opened to release excess storm water into the sea when the tide is low. However, when it is not possible to do so during high tide, drainage pumps will pump out excess storm water into the sea, at a rate of up to 280 m3/sec.

As the water in the Marina Basin is unaffected by the tides, its water level is kept constant all-year-round.

This will make Marina Reservoir an ideal venue for all kinds of recreational activities such as boating, windsurfing and water-skiing.

COVER STORY Project: Enhancing Sustainable Construction through an Innovative Prefabrication Solution - The Spiral Connector system

Organisation: Housing & Development Board Housing & Development Board (HDB) has, over the years, developed and implemented its own fully prefabricated building system, as par t of its effor ts to increase buildability, improve productivity, reduce material wastage and ensure safety in construction works, in order to achieve sustainable construction.

Towards the late 1990s, the use of precast concrete was extended to critical structural concrete elements such as columns, beams and lift shafts.

The Spiral Connector system was developed as a safe, reliable, cost-effective connection system for splicing precast components.

It embraces the theory of ‘concrete confinement and shear action’, to generate the required strength for connecting reinforcement bars efficiently.

The connector system has undergone rigorous tests to meet the high performance standards. Unique in its design, it has been patented in Singapore, China and India.

KFELS SSDT. Image by Keppel Corporation Limited.

Project: Semi-Submersible Drilling Tender Designs (SSDT) Breakthrough New Deepwater Concept

Organisation: Keppel FELS Limited Keppel FELS’s purpose-built Semisubmersible Drilling Tender (SSDT) has established a proven track record for strong operational performance particularly in Southeast Asia.

The first KFELS SSDT, West Pelaut, was designed and built by Keppel FELS in 1994, and was conferred the highly coveted Shell Platform Rig of the Year award in 2004 and 2006.

The trend-setting drilling tender’s successful performance in West Africa proved the design’s resilience and suitability to operate in a variety of challenging offshore environments across the world including offshore Brazil and the Gulf of Mexico.

The purpose-built KFELS SSDT revolutionalised the way in which drilling tenders operate, allowing them to be deployed next to deepwater floating platforms.

With this technology breakthrough, the KFELS SSDT became the first drilling tender in the world to operate in deep waters of about 1,000 m, in the West Seno field, offshore Indonesia in 2003, and to be deployed against a Spar platform in the Kikeh Deepwater Field, offshore Malaysia in 2008.

The KFELS SSDT provides mobile drilling facilities for wellhead platforms - the vessel has a crane which facilitates the transfer of mobile drilling equipment onto the wellhead platform in less than 12 hours.

The deployment of mobile drilling facilities offers several impor tant benefits, compared to the use of a fixed platform with permanent drilling equipment. They include optimisation of equipment lifespans, reduction of environmental footprint and prevention of pollution.

The KFELS SSDT has made it possible for two massive floating platforms to work in close proximity of each other without the risk of a major collision. The KFELS SSDT’s superior hull form provides good motion characteristics needed for it to work alongside another floating platform. KFELS SSDT also features superior mooring capabilities and reliable station keeping for better control.

In addition, the KFELS SSDTassisted drilling concept operates on a ‘safety by distance’ principle, offering high levels of safety to operators, especially during a well control or fire incident. Only five to six people are required to run the KFELS SSDT at a time. Should an emergency situation occur, the KFELS SSDT is able to quickly dislodge from the other platform and enter into a safe standby position.

COVER STORY Project: Reclamation and Infrastructure Development of Jurong Island

Organisations: JTC Corporation and Jurong Consultants Pte Ltd A group of islets, with a total area of some 118 ha, to the southwest of Singapore, was reclaimed individually, over the years, by JTC, after its formation in 1968, and allocated to oil refineries and petrochemical companies. By 1986, these islets had been enlarged to provide a total land area of some 1,000 ha.

But projections of the demand for industrial land showed that there would not be enough land to meet long-term needs.

An idea was then put forward, which was to see if the land stock could be increased by joining up the islands, through the reclamation of land over the waters separating the islands, as well as to enlarge and extend the reclamation in the southwest direction, and see to what extent more land can be created over the sea.

Working on the vision that it was not impossible, a preliminary plan was drawn up and tested. It was found that the idea was hydro-dynamically workable.

Birth of the petrochemical industry In 1989, the decision was made to develop a full-fledged petrochemical industry in Singapore and turn it into a world class petrochemical hub.

Land had to be found and almost all the infrastructure had to be built from scratch. JTC was already planning to reclaim Jurong Island which therefore turned out to be the perfect place to house this new initiative. JTC was appointed as the government agent to spearhead the project, with the support of many agencies including the Ministry of Trade and Industry, Ministry of National Development, Economic Development Board, as well as the

26

then Public Works Depar tment, Ministry of Environment, Public Utilities Board, Singapore Telecom, and others, without which the project would not have been a success.

Challenges There were many challenges in the early days, that had to be dealt with.

Engineering work had to be carried out to reclaim land from the sea, at the same time taking care of the existing tenants who had to maintain their operations while the reclamation work was being carried out. In par ticular, great care had to be taken to ensure that utility cables and pipes, and production lines, were not damaged; there were no disruptions to the jetty operations; and silt was kept away from the cooling seawater intake system.

Owing to the extensive reclamation required, some of the government regulations were ‘put to the test’ when work was carried out.

Early in the planning process, a major change was made to the shipping basins. Two of the basins were removed and replaced with a much bigger basin, named the Banyan Basin. The feedback was that the two basins could cater for only 20,000 DWT to 40,000 DWT ships, and would not be able to suppor t

THE SINGAPORE ENGINEER June 2016

a big logistics hub where ships up to 160,000 DWT would dock. The head of this basin was also made larger so that ships could turn around to sail out of the basin.

More land was required than was originally planned. Hence, to adjust to the revised project needs, the original Jurong Island had to be enlarged. This could be done if the two single buoy mooring (SBMs) in the Sinki Fairway were removed.

Equivalent replacements had to be found for the two SBMs that had to be removed in order to enlarge Jurong Island. The replacements were in the form of two fixed berths.

The decision to link Jurong Island to the mainland by means of a causeway also presented challenges which were successfully addressed.

Customisation To meet customers’ requirements, changes had to be made to the Jurong Island coastal profile, the existing infrastructure, and private utility lines. As a result, the Jurong Island coastal profile had to undergo several modifications before it acquired its present shape.

Completion The reclamation of Jurong Island was completed in September 2009.

Project: Advanced Command, Control & Communication (C3) Solution for Railway Systems

Command, Control and Communication (C3) Solution for Railway Systems. C3 is a collection of distributed software and hardware systems engineered to work collectively to realise the three key needs of Control, Command and Communication, integrated into one single and homogeneous solution for the operator to manage the MRT system efficiently.

This high level of integration between the various major components of a MRT system increases the responsiveness of the system, facilitates the sharing of information between operators and with the commuters, and enhances the overall operability of the system on a dayto-day or incident management basis.

A team was assembled, whose members possessed expertise from

various disciplines, to embark on the large-scale system development. The team included a Project Management team to manage the schedule, coordination with the customer, contractors, interfacing parties and the large resources required for the project, System Engineering team, Software Engineering team, Safety team, Quality and System Assurance team, Installation team, EMC team, Test and Commissioning team and Safety and Software Assessment team.

The journey started in 2003, with the initial funding from the Economic Development Board Innovation Development Scheme. The system was developed in phases to overcome the complexities and meet the customer’s needs. It was deployed in multiple cities along the way.

The major deployment of the Advanced C3 system is in Singapore’s Circle Line.

The successful implementation of this system enabled ST Electronics to contribute its expertise in the deployment of MRT supervisory systems overseas, notably for the Beijing Traffic Control Centre during the 2008 Olympic Games and for the GuangFo MRT lines during the 2010 Asian Games in Guangzhou.

Project: Jurong Rock Caverns

Organisation: JTC Corporation Located 150 m below the ground, the Jurong Rock Caverns (JRC) is said to be the deepest known underground public works endeavour in Singapore to-date, making it an engineering and construction feat.

Adding to the complexity was the challenge of having to construct the caverns 130 m beneath the seabed.

To bring this project from drawing board to reality, developer JTC assembled an international team of experts and specialists and employed cutting-edge construction methods to build five 9-storey high caverns, 9 km of tunnels, and piping networks with supporting utilities. The caverns will be used to store 1.47 million cm3 of liquid hydrocarbons such as crude oil and condensate.

The JRC is located beneath Jurong Island, Singapore’s energy and chemicals hub. Conventionally, above-ground steel storage tanks are built to store liquid hydrocar-

PROJECT APPLICATION

Southern Stack at Crespi d’Adda village Technology was combined with high added value for the renovation of this symbolic tower in a workers’ village that has been listed as an UNESCO World Heritage Site.

Originally built in 1878, the symbolic tower in the Crespi d'Adda village was recently renovated.The work included structural strengthening and static consolidation.

Advanced technology, combined with the latest generation of inorganic matrix composites, including the Mapei FRG System and the Mapei FRP system (fibre-reinforced, polymer matrix composites), were used for the static consolidation and structural strengthening of the Southern Stack in the workers’ village of Crespi d’Adda in Capriate San Gervasio, Northern Italy. The Mapei products were used on this project under the constant supervision of the company’s highly qualified technicians, working alongside the Studio Ing. Giovanni Battista Scolari design studio and the S.M.V. Costruzioni Srl. construction company, right from the very first phases such as taking samples of the materials.

The Crespi d’Adda village takes its name from the Crespi family, cotton magnates from Nor thern Italy.

At the end of the 19th century, the industrialists built a modern, “ideal workers’ village” next to their textile factory along the banks of the River Adda. The employees of the factory were each provided with a house with its own garden and vegetable plot and all the utilities required to run the house.

Only those who worked in the factory were allowed to live in the village and the life of each person and the entire community rotated around the factory, according to the pace and needs of the factory.

On 5 December 1995, UNESCO added Crespi d’Adda village to its

THE SINGAPORE ENGINEER June 2016

World Heritage List as an “outstanding example of a workers’ village, the most complete and best conserved in the whole of Southern Europe”.

Structural strengthening and static consolidation The chimney stack is almost 140 years old and used to be par t of the power station. Today, it stands as an imposing symbol of the village of Crespi d'Adda.

Taking into account the fact that the chimney was built in 1878, the aim of the project was to intervene on the masonry structure and improve its static performance characteristics, thereby eliminating the weak points in the structure and making it safer. The renovation work on the tower, which star ted at the

PROJECT APPLICATION end of November 2014 and was completed in 2015, also included the restoration and protection of the external terracotta facing wall.

The first step was to take samples of the materials and then to check the state of the materials by carrying out pull-off tests. Then, after carefully preparing the substrates with water jets to remove the efflorescence and loose material, a layer of PLANITOP HDM MAXI high ductility, pozzolan-reaction, fibrereinforced mortar was applied by spray, with MAPEGRID G220 alkaliresistant glass fibre mesh embedded in the mortar. The product was applied by starting at the top and working downwards along the length of the chimney.

The aim of this first phase was to strengthen the masonry and even out its surface before applying MAPEWRAP C UNI-AX carbon fibre fabric.

Metal platforms, made up of a fixed part and a mobile part, were then installed inside the chimney, so that the workers could enter the structure to carry out the maintenance work.

The strengthening phase involved applying eight strips of twin-layered MAPEWRAP C UNI-AX carbon fibre fabric (in its 300/20 version) ver tically along the entire length of the stack. The next step was to place a series of hoops made from a double layer of the same MAPEWRAP C UNI-AX fabric inside the chimney, at a pre-set pitch. Four double-layered strips of MAPEWRAP C UNI-AX fabric were then applied in a spiral pattern along the stretch of the chimney, running from 48.5 m to 65.74 m above the ground (the highest par t of the tower). The points where the fabric crossed over were reinforced with extra strengthening ties made from MAPEWRAP C FIOCCO carbon fibre cord.The holes used to house the ties, which were necessary to avoid

having to make holes in the strengtheners applied afterwards, were drilled where required before inserting the ties and then sealed temporarily with removable markers.

The application sequence, using the wet-on-wet technique, began with the application of a layer of MAPEWRAP PRIMER 1 two-component, epoxy primer, followed by MAPEWRAP 11 two-component, thixotropic epoxy grout; MAPEWRAP 31 two-component, medium-viscosity epoxy adhesive to impregnate the fabrics; and, finally, MAPEWRAP C UNI-AX fabrics.

The last operation was to broadcast

the surface with quar tz sand.

To form the ties, the stiff part was moulded into shape by impregnating it with MAPEWRAP 21 two-component, super-fluid epoxy resin, after which the surface was broadcast with quar tz sand.

Once the resin had set, they were inser ted in the holes and fixed in place with MAPEFIX VE SF styrene-free, hybrid vinyl resinbased chemical anchor.

The dry par t of the ties was then splayed out and fixed in place over the fabric applied previously with MAPEWRAP 31 and broadcast with quar tz sand.

For the structural strengthening of the chimney stack MAPEWRAP C UNI-AX fabrics were used after applying MAPEWRAP PRIMER 1.

MAPEWRAP C FIOCCO cord was applied with MAPEWRAP 21 epoxy resin. Once the resin had set, they were inserted into the holes and fixed in place with MAPEFIX VE SF.

Static consolidation For the external par t of the chimney, consolidation work included injecting the cracked areas with a slurry made from STABILCEM super-fluid, cementitious binder. The masonry structure of the chimney was repaired by pointing it with MAPE-ANTIQUE MC lime and Eco-Pozzolan based mortar.

The same product was used to rebuild the missing areas of brickwork, by mixing the render with special oxides to give them the same colour as the original bricks.

CONSOLIDANTE 8020 consolidating product was used to anchor the final broadcasting of sand, and then the entire chimney was protected with a coat of ANTIPLUVIOL S water-repellent impregnator.

Unique challenge The thing that made this strengthening project special was the logistics involved, because the only way of reaching the top of the chimney was to use scaffolding almost 70 m high.

34

Also, the choice to use composite materials for strengthening proved to be the only possible route, thanks to their low weight and easy handling, which are par ticularly impor tant properties, when working at such a great height.

A slurry made with STABILCEM was used to repair cracks on the external sections of the chimney. Final protection was ensured by ANTIPLUVIOL S.

PLANITOP HDM MAXI PLANITOP HDM MAXI is a two-component, ready-mixed, high ductility, pozzolan-reaction fibre-reinforced mor tar.

PLANITOP HDM MAXI is used in combination with Mapegrid G120 and Mapegrid G220 primed alkali-resistant glass fibre meshes or Mapegrid B250 primed alkali-resistant basalt fibre mesh, to structurally ‘reinforce’ stone, brick, tuff and mixed masonry structures.

The system follows the approach defined by the guidelines for the approval of FRCM (Fibre Reinforced Cementitious Matrix) systems which stress the importance of obtaining approval for the entire strengthening package.

It may also be used on its own, to restore the texture of masonry or to level and even out the surface of reinforced concrete and masonry.

CONSTRUCTION MANAGEMENT

Managing risk

by Andrew Merrilees, Director, Hill International Inc

To execute and deliver major public works, it is incumbent that supply chains are properly set-up at the outset and projects are managed appropriately to control risk.

Mr Andrew Merrilees

The tools of risk registers, heat maps, risk dashboards and so-called ‘war rooms’ are only par t of an integrated risk management approach that needs to be not only owned by senior management but must percolate and be par t of an entire organisation’s risk culture.

An integrated risk management system comprises five key parts: • Risk Transparency • Risk Ownership and Strategy • Risk Decisions and Processes • Risk Governance • Risk Culture By adopting these steps, project managers, together with senior design, engineering, commercial and planning personnel, are allowed to focus on the pro-active control and mitigation of risk.

Risk is allocated to the best risk owners across the project, allowing risks to be monitored, controlled and mitigated. Risk governance led by top management is the driver of the constituent par ts, making risk management a priority in day-today work activities.

Every organisation strives to control and reduce costs associated with 36

risk which is unsurprisingly prevalent on major public sector projects.

The type of procurement and form of contract should be carefully selected by the client and other stakeholders, to ensure risks are managed by the most appropriate par ty. There is an ever-increasing demand by clients to transfer the risk of design using Design and Build (D&B) contracts and guarantee cost cer tainty through the use of Guaranteed Maximum Price (GMP).

Thus, contractors must ensure subcontracts and supply agreements reflect the correct level of obligations, liabilities and risks, as contained in the head contract.

It is essential for contractors to engage with technically competent and experienced supply chain entities, from subcontractors to suppliers and vendors that have a proven track-record of executing projects, on time, to the necessary standards and workmanship.

Management should also give due regard to the importance of programme management. The recording of actual progress against plans has to be more systematic, with regular updates showing the effects of delays and the impact on overall project completion. The control of time is paramount to effective risk management.

In general, most time and cost overruns are avoidable and can be solved by a robust risk management regime that manages risk in all stages of the value chain and throughout the life cycle of a project.

An integrated risk management system identifies possible risks and assesses the likelihood of occurrence and impact on a project’s time and cost parameters that are

THE SINGAPORE ENGINEER June 2016

ultimately controlled by the appropriate risk owners.

Organisations in the construction industry should remain bold and embrace best practices to ensure nothing is left to chance. By managing risk and providing solutions for the delivery of projects, competitive advantage will become the norm.

building and Offshore Association (IPERINDO). A conference track dedicated to Indonesia was also held for the first time at APM 2016 to harness available oppor tunities in the country.

Yeow Hui Leng, Senior Project Director, Reed Exhibitions, organisers of APM, said, “The strong participation from international exhibitors and visitors on the ground is especially encouraging. As a platform that facilitates networking with prominent players, we believe that such robust interaction has helped establish the momentum for the industry to sail forward when the economy eventually recovers".

players must start by first "identifying the issues that hinder the promotion of LNG. It is only after that, can the industry keep improving and revitalise their policies to make it attractive to the market".

Exciting and insightful exchanges were also heard at the market landscape conference ‘6 questions in 60 minutes’. Peter Sand, Chief Shipping Analyst, BIMCO, said that Asia is at the helm of the world shipping economy, and that it is in a prime position to influence global shipping.

He added, “We hold the key to the solutions in the shipping industry, and can balance out the demand situation in the market”.

Fellow speaker Mark Charman, CEO of Faststream Recruitment Company, highlighted the glut of jobs available in cer tain segments of the maritime industry. He said that oppor tunities abound for electrical engineers, as well as crew on liquid natural gas carriers, cruise ships and oil tankers. He added that workers must work efficiently and constantly enhance their skills to remain employable, concluding, “Change is the common factor in the maritime sector at the moment. We can fight it, or we can roll with it”.

The next edition of APM will be held from 14 to 16 March 2018.

Asia Pacific Maritime 2016 (APM 2016), Asia’s premier trade exhibition and conference for international marine, workboat and offshore communities, concluded on an upbeat note amidst strong headwinds and conservative sentiments.

Held from 16 to 18 March 2016, the three-day event attracted 14,954 visitors. A total of 1,521 exhibitors from over 60 countries and 17 official pavilions showcased their cutting-edge products and technologies on the exhibition floor.

Despite the industry slowdown, exhibitors reiterated the importance of par ticipating in a maritime trade exhibition that is Southeast Asia’s largest. One good example is leading maritime engine player, Cummins, who leveraged APM 2016 and unveiled its QSK95 diesel engine in the Asian marketplace for the first time.

APM 2016 also saw active Asian participation, including a strong presence from Chinese companies. Weichai Power Co Ltd is one such company that believed in the value of participating in APM 2016.

Maritime leaders call for adoption of technology Maritime leaders are calling on the industry to adopt new technology as a way to capitalise on opportunities and navigate today’s increasingly complex operating environment. This is the response from CEOs, chairmen and directors of maritime and offshore companies, to a survey conducted by Sea Asia in the lead up to Sea Asia 2017.

Nine in 10 (94%) of the leaders surveyed believe that it is time for the industry to make the move towards smart shipping while another 81% recognise the importance of Big Data to the future of the shipping and maritime industry. Leaders surveyed also highlighted that new technological developments are crucial in helping industry players transform the way their businesses operate sustainably.

Chairman of BW Group and the Singapore Maritime Foundation, Andreas Sohmen-Pao said, “The global economic, political and technological environment is changing, and the maritime industry needs to change with it. As we look for ways to adapt our business model, forums like Sea Asia provide a good opportunity to exchange ideas and find new solutions”.

Group Chairman of Taiwan’s UMing Marine Transport Corp, Douglas Hsu, added that the industry is still at the beginning of this journey.

“A small number of industry players are shifting towards smart shipping.

However, with technology developing at a fast pace today, it is important that the industry adapts quickly. To encourage this shift, industry players need to realise the benefits of welcoming technological changes in the industry”, he said.

Across the region, the industry is working alongside government and private sector par tners to drive the development of technology and innovation to help ensure it is well positioned to capture new oppor tunities and navigate new trends and challenges.

In Singapore, for example, the

Maritime & Port Authority of Singapore’s Maritime Innovation & Technology (MINT) Fund has been enhanced to include the MINT-PD (Product/ Solution Development) scheme. This scheme supports up to 50% of qualifying costs for projects that seek to develop technology products or solutions for the maritime industry.

Through this scheme, companies are encouraged to build on existing research and development (R&D) activities and harness technologies from other industries to develop new innovations for the maritime industry.

Meanwhile, China is encouraging the development of smart ships. In May last year, the State Council announced the ‘Made in China 2025’ policy which highlights the development of the world’s first smart ship as a priority.

Managing Director of Precious Shipping Ltd, Khalid Hashim highlighted the benefits smart shipping technology can provide.

“Smart technologies in shipping will help optimise ship operations and improve ship-to-shore communications and vice versa. For example, new technologies can better enable the communication of loading and discharging schedules, and more importantly, give crew members the opportunity to stay in touch with their loved ones on shore", said Mr Hashim.

Industry leaders also commented on the importance of harnessing Big Data.

Mr Hashim said: “The collection of Big Data is important in helping ship owners evaluate the performance of their vessels. By utilising the data collected in areas like machinery parameters, fuel consumption and vessel speed, ship owners can then look into how they optimise further the capabilities of their vessels”, he said.

Big Data is another area where the industry is working with governments and other partners.

In Indonesia, for example, the government is bringing together data from 24 ports, to monitor perfor-

mance and ultimately reduce waiting time for ships and cargo. This data will also allow ship owners to monitor their containers in real-time, enabling them to see if they have arrived safely and on time at destination ports.

In Singapore, the Maritime and Port Authority of Singapore (MPA) is collaborating with leading IT company, IBM, to create a unified platform which will integrate real-time data and provide a consistent view of data points across MPA. This platform will collect information such as vessel positioning and weather data.

Leaders surveyed said that while there are significant benefits from this technology, the initial cost of integrating it is a barrier to adoption.

Seatrade Chairman, Chris Hayman, said the industry needs to work together - and with technology companies - to embrace new technologies and find ways to make smart shipping infrastructure more accessible.

“Technological developments in the maritime sector, smart shipping and the utilisation of Big Data will be among the topics of discussion at Sea Asia 2017. Maritime leaders will be debating with one another, as well as with experts in the technology field, the benefits of smart shipping and Big Data and exploring opportunities on how best to leverage these new trends with others in the maritime sector. Sea Asia has traditionally drawn high-level leaders in the global maritime scene, and next year will be no different with some of the biggest names in the industry debating, discussing and analysing key issues shaping the industry at the three-day event”, he said.

Sea Asia The 6th edition of Sea Asia, an international conference and exhibition for the maritime and offshore industries, will be held from 25 to 27 April 2017, at Marina Bay Sands, Singapore. Sea Asia is co-organised by Seatrade and the Singapore Maritime Foundation.

He highlighted three broad directions for Singapore’s future built environment - an accessible and connected built environment, a green and smar t built environment, and a productive and high-tech built environment.

EXCERPTS OF SPEECH BY MR LAWRENCE WONG An accessible and connected built environment First, we must design buildings for all ages and all abilities. I think this is an integral par t of what we want to be as an inclusive society.

It is also an important strategy to meet the needs of an ageing population. Our demographics are changing very quickly, our population is ageing and by 2030, the proportion of seniors will double.

Gentle sloping ramps, accessible toilets - all sor ts of things that will go towards Universal Design - these are features that Singapore’s society will need in the future. Today, most of these features are already installed or implemented in our public sector infrastructure, but it still can be better, and cer tainly in the private sector buildings, there is scope for improvement.

For new buildings, cer tainly Universal Design can be incorporated at the design stage. We should also make effor ts to retrofit existing buildings. Besides improving accessibility within the

42

buildings, we also need to look at accessibility between buildings.

A green and smart built environment The second strategy is to look at how we can have buildings that are more environmentally friendly.

Buildings account for one quarter of total carbon emissions in Singapore. That is not sustainable and we should really think of being more environmentally friendly. That means having to cut back on energy usage and carbon emissions from buildings.

That is why we have been making this push for green buildings and having all these different Green Mark cer tifications, to encourage building owners and developers to push for green building features.

A productive and high-tech built environment Finally, we need to push forward with changes to the way we build - how we can be more productive and how we can adopt more high-tech solutions in the way we build. I think we have already

THE SINGAPORE ENGINEER June 2016

made some improvements in this area, but many of our construction methods are still labour-intensive and time-consuming.

We must accelerate this move towards a more productive and high-tech built environment sector supported by a skilled workforce.

One way to achieve this is to adopt the Design for Manufacturing and Assembly approach, or the DfMA approach. Basically, to think about construction as a way of design and manufacturing, so that it can be more productive and high-tech. With the works being mechanised and done off-site, we can build faster, safer, with a leaner workforce and with less impact to the surrounding environment.

By changing the way we build, it will not only help us in the built environment sector, in the outcomes that we see for our buildings and our urban landscape, it will also create better career opportunities for Singaporeans. It will change perceptions of what this sector is about, and potentially it can attract more young people to join the sector.

Onshape introduces full-cloud CAD to Singapore Onshape, a company that is 100% focused on cloud and mobile CAD, has opened regional offices in Pune, India and in Singapore, signalling its entry into the Asia Pacific markets.

“Even though Onshape is only a few months out of beta, engineers and designers in more than 150 countries are already experiencing the benefits of full-cloud CAD”, said Mr John McEleney, CEO of Onshape.

“The design and manufacturing world has dramatically changed. More often than not, design teams are spread across multiple countries and time zones - and Onshape is the first and only CAD system specifically built for distributed teams”, he added.

Built from scratch, using a cloud-based technical architecture, Onshape has already achieved, what the company claims as ‘historic firsts’ for professional 3D CAD. The company’s 3D CAD system: • Runs on any computer completely within a web browser (on PC, Mac, Linux, and Chromebook).

• Delivers full CAD functionality on phones and tablets (Apple iOS and Android), and not merely a mobile view.

• Provides instant and controlled collaboration and sharing. It is said to be the first CAD system enabling multiple people to simultaneously work on the same model.

• Includes built-in version control, eliminating the need for a PDM system.

• Requires absolutely zero IT support (no installation, no licenses and no updates to manage).

• Will soon allow users to customise their CAD system with FeatureScript, a new programming language that allows one to create one’s own built-in features for Onshape and modify existing ones.

• Offers multiple choices of fully-integrated, cloudbased CAM, Rendering and Simulation tools.

Onshape customers repor t that the benefits of fullcloud CAD include speeding up production, improving collaboration, increasing innovation, saving time, boosting security of one's IP, and saving money on software and hardware.

Engineers and designers who use Onshape also say they are now enjoying their jobs more. With no installs, downloads or data management to worry about, CAD users can now primarily focus on the creative process instead of administrative tasks.

“Because there are no files to copy - your CAD data and CAD system lives in one central place in the cloud - your intellectual proper ty is now far more secure.

You can easily grant and withdraw permission to access your models in Onshape, in contrast to files shared by email”, said Mr McEleney.

With automatic upgrades in the cloud every few weeks, Onshape has also eliminated the software in-

compatibility problem that slows down many design and manufacturing partners who share files. Every Onshape user in the world is always on the same version of Onshape - the latest one.

Over the last year, Onshape has released 20 major product updates with more than 175 new fea- Mr John McEleney, CEO of Onshape. tures and enhancements.

Users do not need to download anything, they just refresh their browsers. The full-cloud CAD system is now approaching 1,000,000 user hours.

As a complete engineering solution, Onshape now offers integrated cloud-based CAM, Rendering and Simulation tools through the Onshape App Store.

With the convenience of using the Apple App Store or Google Play, Onshape users can try and compare solutions for free and only buy what they need. Additional technology par tners will be introducing new products in the App Store soon.

Onshape’s pricing, which includes a Free Plan and a US$100 monthly Professional Plan, lowers the economic barriers for entrepreneurs and star tups to succeed.

But established companies of all sizes are also discovering Onshape’s benefits alongside their existing CAD systems. They find value in simultaneous editing, branching with intelligent merging, version control, and having a complete edit history of all activity.

Companies worldwide are using full-cloud CAD to speed up the design of consumer electronics, mechanical machinery, medical devices, machine parts, industrial equipment, and many other products. More information can be obtained from Onshape.com/customers.

The Onshape 3D CAD system runs on any computer within a web browser and delivers full CAD functionality on phones and tablets.

Aurecon helps recreate Macau’s skyline

The Macau Eiffel Tower will form part of The Parisian Macau, an integrated resort, which is currently under development by Sands China Ltd, a subsidiary of resorts giant Las Vegas Sands Corp. Image by Hsin Chong Engineering Macau.

A faithful replica of one of the world’s most recognisable structures now stands in the midst of Macau’s busy centre.

The tower is half the size of the Eiffel Tower in Paris and retains many decorative features of the original, including cornice scrolls, balustrades, gussets plates, lattices, staircases and mesh screens around the observation decks.

Construction of the Macau Eiffel Tower was completed with a topping out ceremony held on 15 October 2015.

The tower will form par t of The Parisian Macau, an integrated resort, which is currently under development by Sands China Ltd, a subsidiary of resor ts giant Las Vegas Sands Corp.

Global engineering consultants Aurecon was closely involved in the planning and design for the distinctive new structure. The company provided full structural engineering consultancy on the job and helped manage the difficulties of maintaining an authentic design while addressing the challenges caused by extreme weather, a congested construction site, and the anticipated high number of visitors.

At the project’s outset, Aurecon provided the drafting of the tower using Revit software, which allowed the team to visually represent the complicated design connections in 3D. This made it easier to detect any potential challenges or clashes that might arise during construction even before building work had begun. As a result, time-consuming amendments at the shop drawing preparation or fabrication stage were avoided.

THE SINGAPORE ENGINEER June 2016

“The key to recreating this iconic landmark has been strong team work and the close collaboration between the design and construction teams”, said Dr Alecs Chong, Aurecon’s project leader on the Macau Eiffel Tower.

Dr Chong said the close co-operation between the design and construction teams started at the earliest stages of the project, and delivered efficiency improvements from the beginning.

“The original structural performance criteria for this project were specified at an early stage and were largely based on the criteria commonly used for conventional office or residential buildings”, he explained.

“However, given that the tower behaves as a slender, open-lattice structure, some of the serviceability performance criteria were too conservative and after consultation with stakeholders, these were subsequently relaxed. So, clear communication between the design and construction teams, supported with sound technical evidence, delivered an outcome that would allow the design team maximum flexibility”, Dr Chong added.

Wind-loading for typhoons Among the biggest challenges for the design team was addressing the issue of typhoons which occur seasonally in Macau. In particular, the design team had to ensure it made the correct critical wind loading calculations for the tower in the event of a direct hit from a typhoon.

“We used the Equivalent Static Wind Loads (ESWL) approach developed for towers to determine the critical wind loads”, said Dr Chong.

INDUSTRY NEWS “We also ran a series of studies to investigate the wind-induced dynamic response at the tower’s top peak at various wind speeds. And we then looked at the subsequent impact on human comfor t in terms of potential vibrations. Our thorough investigations and scenario planning allowed the project team to ensure not only an aesthetically pleasing and accurate design, but also a safe one”, he added.

A fur ther challenge for the design team was accounting for the very high number of visitors the attraction is likely to draw. In particular, said Dr Chong, they focused on the footbridge that will connect the tower with an adjacent casino complex.

“After discussions with the developer, we knew that anticipated visitor traffic on the footbridge would be high as it is the main access point between the hotel complex and the tower. As a result, we adopted an acceleration-based vibration assessment method to review the bridge’s design, taking into account the loading caused by crowds walking. We used superposition to look at responses caused by various vibration modes to get to an overall vibration response, which we then established was within acceptable human comfor t levels”, he added.

Materials and equipment Outside of the challenges directly linked to the tower’s design, Aurecon and its par tners also had to contend with some more practical difficulties related to the construction work - specifically, how to get the large steel sections needed for the tower’s construction to the job site and, once there, how to assemble them.

“The por t of Macau is neither large enough nor deep enough for the vessels that would normally deliver the oversized steel sections needed. As a result, the job had to request for shallow-hulled vessels, but this limited delivery capacity. This, in turn, meant we had to plan the size of the delivery racks, to maximise delivery capacity and minimise delivery costs which were estimated as being anything up to a quar ter of the overall material cost”, said Dr Chong.

And on the job site itself, there was a challenge presented by the selection of the tower crane needed to place the steel and other building materials.

“On a traditional concrete building, the tower crane is attached to the construction as it climbs, offering lateral rigidity so the crane can be raised higher and higher. But because the replica Eiffel Tower is such a slender structure, the suppor t for a regular tower crane is not there. The tower crane selection was therefore a complicated process that required full collaboration between the construction manager, the design engineer and the tower crane manufacturer because we had to select a crane and configuration that would avoid large lateral loads being transferred to the tower”, Dr Chong explained.

The solution came in the form of a luffing jib crane, which can articulate its jib between the horizontal and near vertical angles. Using such a crane, and fitting it with a shorter jib, meant less of the lifting force was distributed laterally and more was directed down the crane’s mast.

With a maximum hoisting capacity of 28 t, the crane facilitated the modular construction method on site, overseeing the fast and safe installation of building elements.

Overall, being involved in the recreation of the Eiffel Tower at the Parisian Macau Integrated Resort has been a hugely challenging yet rewarding venture for the team at Aurecon.

“Recreating the Eiffel Tower using modern steel construction technology is vastly different from working with the wrought-iron that features on the original.

Extensive consideration had to be given to disguising the modern steel construction while, at the same time, achieving a cast-iron lattice appearance. It has been immensely satisfying to see this truly inspired structure come to fruition. And it has been rewarding to see how the extensive use of advanced techniques such as finite element analysis and 3D drafting and shop drawing preparation have delivered successful solutions for the design, fabrication and erection of the complex lattice geometry on this project”, said Dr Chong.

Spectacular views Standing next to another distinguishable Sands development, The Venetian Macau, the replica Eiffel Tower at the Parisian Macau is set to become a landmark feature whilst offering guests and visitors alike spectacular views of Macau’s bustling Cotai Strip.

Autodesk and Trimble sign agreement to increase interoperability Autodesk and Trimble have entered into an interoperability agreement aimed at saving customers time and reducing project costs typically associated with workflow inefficiency across different suppliers’ technologies. This will benefit architects, engineers and contractors, and importantly, project owners, by enabling more freedom to optimise technology workflows needed to meet the complex requirements of construction projects.

Autodesk and Trimble have a shared goal of meeting the evolving needs of the building and infrastructure industries. Their collaboration demonstrates an ongoing commitment to suppor t open industry standards such as Industry Foundation Classes (IFC) and Construction Operations Building Information Exchange (COBie), and can enable Autodesk and Trimble customers

working on the same projects to work together seamlessly through optimised file compatibility across applications.

Under the terms of the agreement, Autodesk and Trimble will take steps to accelerate interoperability by exchanging Application Programming Interfaces (APIs) and developer tools to build and market interoperable products. This allows the two companies to improve upon existing data exchanges, as well as open up new workflows between their products. Tighter product-to-product integration can enable design and construction professionals to share models, project files and other data between select Autodesk and Trimble solutions both in the office and the field, and allow for the reuse of information throughout all phases of the project, from design to construction.

“The strength of a company is best measured by its willingness to do what is right for its customers and the industry at large. This interoperability agreement, like others we have signed, speaks to Autodesk’s commitment to openness. This collaboration with Trimble speaks to our shared dedication to making the building process more efficient and productive for all involved”, said Amar Hanspal, Senior Vice President, Autodesk.

“This collaboration demonstrates our mutual commitment to provide design and construction professionals with a seamless experience from both Autodesk and Trimble design-build-operate solutions. As a result, all stakeholders across the construction lifecycle can optimise their workflow efficiency”, said Bryn Fosburgh, Vice President at Trimble.

New I-Shift with crawler gears can start off from standstill with 325 tonnes In the I-Shift with crawler gears, from Volvo Trucks, the new gears, which are added to the automated transmission, provide exceptional startability for trucks carrying heavy loads in demanding situations.

Volvo Trucks’ new version of I-Shift makes it possible to add up to two new crawler gears.

This means, among other things, that the truck can move off from standstill and transport a gross combination weight (GCW) of up to 325 tonnes.

“I-Shift with crawler gears offers an entirely new scope for heavy trucks with automated transmission to regulate their speed when crawling slowly and reversing. The driver can haul a heavy load without getting into

46

situations that may lead to costly standstills”, said Mr Peter Hardin, Product Manager FM and FMX, Volvo Trucks.

With the new crawler gears, the truck can drive at speeds as low as 0.5-2 km/h. This helps during precision manoeuvres such as in construction and maintenance tasks.

“The vastly improved driveability and startability with the new crawler gears make the driver’s job far easier when operating in difficult terrain on slippery surfaces with heavy loads, such as at construction sites, in mines or in forests. The heavier the transport operation and the poorer the surface or the terrain, the more the driver gains from a truck with crawler gears”, explained Mr Hardin.

Hong Kong debut for Liebherr heavy-lift luffing jib crane The first Liebherr 540 HC-L 16/32 Litronic luffing jib crane to be used in Hong Kong has been installed on the re-provisioning of Kennedy Town Swimming Pool.

The original pool, which opened in 1974, was displaced by the construction of the MTR West Island Line.

A second Liebherr luffing jib unit, the newly released 357 HC-L 18/32 Litronic, has recently been installed.

The main contractor on the project is Paul Y Construction Co Ltd. The company is undertaking the work on a HK$671 million contract from the MTR Corporation.

Both of the cranes are being used on a rental agreement with Liebherr Singapore.

The 540 HC-L is one of the heaviest-lift luffing jib cranes in the Liebherr range, having a capacity of 32 t at a jib reach of 15 m, and 5.2 t at the full 60 m jib length.

The 357 HC-L can handle a maximum load of 32 t, and 4.0 t at 55 m radius.

Mr Wilson Chan, Manager, Liebherr Singapore, said that there is a strong trend in Hong Kong now towards the use of prefabricated building elements, which means that heavier lift cranes are increasingly needed.

“Seven Liebherr luffing jib units were brought into Hong Kong last year, including the two that are being used on this project, and that is a record. We have never taken delivery of so many luffing jib cranes in such a shor t period of time”, he added.

Mr Chan said that the restrictions on the site, with busy roads on either side, together with overhead cables supplying power to the trams, meant that luffing jibs were essential.

Two cranes are needed because of the long, linear footprint of the site.

Architects TFP Farrells have designed the new pool complex, which covers 11,782 m² and is being built in two phases.

Phase I, which includes an outdoor secondary pool and a leisure pool, opened in 2011. Phase II is now under construction and will include a multi-purpose pool, a teaching pool and a Jacuzzi.

The sleek modernist structure is set beside Victoria Harbour, with views of the ocean from the pool deck, and is located at the entrance to Kennedy Town when approached from Central district.

Phase II is currently at foundation stage, with piling, excavation and lateral suppor t being undertaken. Bored piles, mainly 2 m diameter, are being installed, using a rotator for casing installation and reverse circulation drill for rock drilling.
