The President’s CornerDear fellow-members,The gloom that hung over theconstruction industry in thepast few years appears to begradually dissipating. Withcautious optimism, we arelooking forward to the growingnumber of projects in theMarina Bay, Sentosa, JurongIsland, Orchard Road and otherparts of Singapore. They willgive the construction sector amuch needed fillip.

After an eventful 2006, our society is all set to face year 2007with renewed vigor. We will kick off the year with aninteresting evening lecture on 17 January at the Furama RiverFront Hotel. The two speakers, who are co-inventors of theLysaght Smartruss roof framing system will speak onLightweight Steel Trusses.

This will be followed immediately (in February) by the startof the second run of our Qualified Steel Supervisors Coursefirst launched in August last year. We anticipate a full class ofmore than 50 trainees in this run, after the overwhelmingresponse for our inaugural course.

Our Scholarship fund raising efforts have brought us close toour target of $150,000, and we are all ready to award the firstSSSS-BCA scholarship for undergraduate studies in the Civiland Structural Engineering course at NTU or NUS.

We also look forward to organizing the very popular annualSSSS-Continental Steel Golf Challenge in the middle of theyear. Golfing enthusiasts from the industry can once againgather for a day of interaction and fun.

We will wrap up the year with our Annual Lecture and Dinner.After the fantastic turn-out and outstanding lecture given byour special guest lecturer in 2006, it will be a challenge forour council members to try and match the standard set lastyear – but I am sure we will be up to it.

Our other educational and training activities such as site visits,evening talks, seminars and corporate members’ gatheringsare also in the pipeline. Watch out for these in our circularsand SSSS website.

I wish all of you a great year ahead and hope you will participatefully in the various activities that your society has lined up foryou in 2007.

Warmest Regards,Tan Tian Chong

Site Visit to Fusionopolis at Ayer Rajah Avenue

At 13,800 tons of permanent steel, the Fusionopolis is perhaps the largest steelbuilding project in Singapore. Located between Ayer Rajah Avenue and PortsdownRoad, Fusionopolis’ unique design consist of 3 tower blocks of 23/24 stories highlinked by sky bridges with an auditorium perched above a single column supportheld up as high as six stories above the ground floor.

On 2nd October 2006 Singapore Structural Steel Society members visited theFusionopolis construction site. SSSS members were welcomed by the main con-tractor Shimizu Corporation and introduced to the project with a slide presenta-tion that included the design concept, visuals and technical aspects of the project.The group was split into three groups and the site visit ensued.

A key point of interest was the cast node on top of the 2.5m diameter columnsupporting the auditorium. Cast in China the node is approximately 18 tons andsupported by 4 inclined columns.

Cantilever trusses at 4th, 11th, & 18th floors are constructed by casting in supercolumns into the reinforced concrete core walls, linking the super columns be-tween the core walls and cantilever the trusses out. Post-tensioning was incorpo-rated in the cantilever truss top chords to provide compressive forces. Perimetertrusses tie in the trusses on the perimeter of each tower.

Yongnam Engineering Pte Ltd proprietary strut system was used as temporarycolumns to support the end of the trusses as well as to provide a temporary plat-form for the construction of the auditorium.

A mock up floor at Tower A 6th storey was completed and perimeter claddinginstalled. SSSS members got a first hand look at the finished product.

The time provided for the construction was short and steel was the only way toallow concurrent activities to take place. Maximum preassembly and weldingwas carried out at Yongnam’s production facility, which had an output of 1,700tons a month allocated for this project. Preparation of shop drawings in a situa-tion where there is constant design refinements and where the steel structure wascontinuously being re-engineered to reduce the amount of steel made this a verychallenging project.

Vertical access is very crucial to the overall success. Provision of man hoist, scaf-fold access to install typical floor beams and allowing follow on trades to proceedis important, and if momentum can be built up the works proceed at a faster pace.

Living Steel - World Steel Construction Council (WSCC) meeting

The first Living Steel World Steel Construction Council(WSCC) meeting was held in Bilbao, Spain on 16th and17th October 2006. The event was attended by 40participants from 20 organisations across the various regionssuch as Canada, Chile, Europe, South Africa, UK, India,China and Singapore.

The WSCC (as the forum for supporting members of LivingSteel) meeting focused on the issue of sustainability withgreater emphasis in residential construction. It was reportedby the Chairman, Mr Graham Owens, Director of SCI, thathousing is the least successful in terms of steel constructionbut offers the biggest potential for growth and developmentfrom a global perspective. Some of the questions raisedwere as follows:

1. What is the current attitude of commercial clients tosustainability, and opportunities and threats these create forsteel construction?

2. What are the current dynamics of dissemination ofsustainable building projects made of steel?

Various perspectives from different organisations presentedtheir local conditions, steel market, and regional surveys forthe issues of steel sustainability in housing. It is interestingto note that in Northern America, there is an uphill battle toreplace traditional timber frame construction. Similarly, inSouthern European countries like Italy and Spain have astrong lobby group for concrete construction and design.While, China, being the nation for rapid developments forthe last twenty years, has been consuming steel on an

unprecedented scale. It remains to be seen if steelconstruction can be further infiltrated into residential designto make an impact.

Globally, it seems the issue of sustainability has become akey consideration in future market (politically and socially)and it offers as an important concept along the supply chainof steel design and construction. The first Living SteelArchitectural Competition – Winning Projects werepresented and the 2nd competition was launched. Worldwidesteel design communication and education is another areawhere steel design can be effectively targeted at the entiresupply chain from client, consultants, contractors,fabricators, quantity surveyors to end users.

The presentations on sustainability was the opening sessionof the second day of the WSCC meeting, which consistedtwo presentations from guest speakers, Liza Bowles(Newport Partner) and Chris Twinn (ARUP). Liza spokeabout sustainability related opportunities for steel inresidential construction whereas Chris gave a presentationon Dongtan eco city. The presentations were followed byan open discussion on possible opportunities for the steelindustry in relation to sustainability issues. Among the ideasgenerated during the discussion, it was proposed Living Steelto partner the Green Building Council.

There was a steel house demonstration building to be usedfor exhibition around the world, its concept was mooted byone of the steel organisations in Spain to exhibit anddemonstrate steel versatility in housing in various locations.The concept can be further refined to incorporate local steelstakeholders to participate in such projects and the idea of avirtual model rather than a real one was stronglyrecommended.

The 2-day event ended with many food-for-thoughts forvarious member organisations to promote and help to spurthe growth of steel into a sustainable future. From a globalperspective, the steel market can be further consolidated andenhance its potential in the residential market.

Hence, the challenges are perhaps summarised in the futureon the last-day workshop. Living Steel plays its role by fillingin the information gap and serves as a valuable forum forknowledge dissemination and sharing.

The discussions within the three groups generated interestingthoughts, and put high value on leveraging existing

knowledge through information sharing among members.In particular, it was proposed to launch a survey on existingresidential steel buildings (including demonstration buildingsalready built) with the aim of gathering data on buildingsperformances. This survey should provide quantitative andqualitative information on a set of variables, which can berelated to the following segmentation: comfort, value andefficiency.

The organiser, Living Steel thanked all the memberparticipants and would likely to convene another meetingabout 10 months time to kick start some of the concept /ideas generated by the members during the 1st WSCCmeeting.

The Society with Corporate Member Yongnam Engineeringand Construction Pte Ltd, played host to a brief visit fromthe Chilean Steel Institute on 20th November 2006 atYongnam’s offices in Tuas. The visitors were on a businessmission to China (Beijing and Shanghai), with stopovers atHong Kong, Kuala Lumpur and Singapore. The delegationwas led by Joan Teng of the Chile Embassy CommercialDepartment in Singapore and Mariano Nicolas – CEO ofthe Chilean Steel Institute.

The Chilean Steel Institute is a non-prof it privatecorporation; their primary objective is to develop activities

to form a technology transfer centre, forming their “SteelValue Network” within the industry.

During the visit, Seow Soon Yong – CEO/MD of Yongnamgave an introduction of his company and showed manyprojects, both completed and on-going ones which impressedthe delegation very much in terms of size and complexity ofthe structural steelwork being fabricated and erected. Thevisit ended with a tour of Yongnam’s fabrication facilities.

Many engineers, including LTA and various consultants, haveasked the question of whether used strutting materialdiminishes in strength with age. Yongnam, being a majorplayer in the local strutting industry, have proactively carriedout a full-scale test to address this fundamental safetyconcern.

Yongnam carried out a full-scale load test on its proprietarymodular strutting system at its fabrication plant in Tuas onthe 8th November 2006. A full-size test of this scale andmagnitude is believed to be the first ever to be done inSingapore. A full-sized 20m long double-laced strut systemwas tested in collaboration with the National University ofSingapore to its ultimate failure load, with full monitoringof stresses and deflections with strain gauges and transducers.

Prominent guests from the construction industry were invitedto witness this event. More than 300 invited guests frommajor contracting firms; LTA, MRT, BCA, academicinstitutions, universities and engineering consultantsattended the event.

The main test objectives are to determine the safe capacityof a used Yongnam’s Strut System and compare with actualdesign loads. The significance of this test is of paramountimportance to the local construction industry, as theYongnam Strut System is widely used on LTA, MRT,building, basements and general civil engineeringapplications.

Amongst the various technical and scientific documentationsrecorded from the test, the following summarizes the overalltest results. At a failure load 1438 tons which is about 2.0times the safe working capacity of the strut system, the testconfirms the following main points:

Yongnam Strutting System

(1) The predicted failure load of the strut based on BS5950:Part1:2000 is 995 tons. Based on the design safety factor of1.4, the working load is 710 tons. The actual collapse loadof the test specimen is 1438 tons. The actual factor of safetyagainst the design working load is about 2.0. The loadcapacity predicted by the codes is found to be on theconservative side.

(2) Forces induced in lacings are less than 1% of the axialload, as compared with current codes of practicesrecommendations of 2.5%.

(3) The current size of lacings is not critical and it does notgovern the strut ultimate capacity; hence there is no need toincrease lacing size for all future projects. This relatesdirectly to an economical and cost-effective strut system.

(4) An old and reused strut does not diminish in strengthover the years. This relates to the significant point that strutscan be repeatedly reused over the years, hence leading toeconomical operational advantages if proper maintenancesystem is installed.

(5) The strut connection joints are not the critical failurepoint; since the failure is the mid span buckling of the topflange. This relates to economical design of strut joints.

This report ultimately proved to be of tremendous benefit tothe overall strutting business objectives in many aspects.Developers, main-contractors, engineering consultants andauthorities will find that the test result gives a level of safetyand product confidence that is unparalleled in both Singaporeand globally, as Yongnam continues to spread the use of itsstrutting system globally to other countries such as HongKong, Thailand, India and the Middle-East.

The Late Mr Leonard Soh

Mr Leonard Soh, our immediate past President is no longer with us. He died in hissleep. The President and other Council members of the Singapore Structural Steel Societydeeply mourn his loss. We shall miss his famous calling “hello, hello” forever. We shallno longer see his ever smiling face at our Council meetings.

Mr Leonard Soh was President of the Singapore Structural Steel Society (SSSS) from2003 to 2005. Prior to this he served the Society in various capacities for more than 10years. During all these years he worked tirelessly to encourage the use of steel as well asimprove the quality of steelwork in Singapore. He was a visionary and worked hard toachieve his vision. He was the prime mover behind the Structural Steel Supervisors’course now being conducted regularly by the SSSS to update and upgrade the knowledgeof steel supervisors as well as the accreditation of steel fabricators scheme.

Leonard was a man with a big heart. Donating generously was his second nature. Hestarted the Continental Challenge Trophy Fund Raising Golf Tournament where not

only he himself donated generously, he also actively raised funds. It was his idea to offer scholarships to encourage studentsto study Civil and Structural Engineering at tertiary level with funds thus raised. Today, SSSS is offering scholarhips to thestudents of Universities and Polytechnics. He himself regularly donated large sums to the President’s Challenge as well as theUniversity Endowment fund of NUS and NTU. Other charitable organisations such as Singapore Red Cross, National ArtsCouncil, Community Chest, the Courage Fund also received regular donations. In short, anyone who approached him fordonations for good causes never returned empty handed.

In addition to his association with Singapore Structural Steel Society, he was also an Hon Patron of Bukit Gombak CommunityCentre Management Committee and a member of the Singapore Metal and Machinery Association. He was very successfulin business as well. Under his leadership, Continental Steel became a leading steel supplier in Singapore and in the region.Those of us who worked with Leonard would never forget his warm and friendly personality.
