With activities of this session about to end in Oct2013 I think it’s appropriate to highlight the activitiescarried out in this session in the context of the

overall objectives I laid out when I took over the presidency. Inmy inaugural address I had stressed the need to bring IESL toits members with the use of information technology as astrategy to serve the country through serving the membershipof the institution. Infusion of new technologies combined with overhaul of itsinternal processes have vastly upgraded IESL to a modernday professional body giving transparency and accountabilityin addition to timeliness and efficiency. All membership services are now integrated through a newMembership Management System and user friendly websiteto provide a personalized One-Stop Shop membership serviceto which members are being gradually acclimatized to obtainmaximum usage and benefits. IESL is now Globally Connected and members need only aPersonal Computer and Internet Connection to participate inthe institution’s activities that hitherto been difficulte due todistance and time barriers. Public lectures held in Colomboand overseas are being live streamed to be watched bymembers from wherever they are. Members in overseaschapters and provincial centres are interacting through SKYPE,etc at meetings of the institution. ‘B Paper’ lectures areuploaded in to the website and being viewed at their convenienceby those aspiring to be chartered engineers in the provinces. Expanded potential of provincial certres for group activities invirtual participation with the head office and other provincialcentres makes it necessary to have permanent places of theirown to effectively carry out their enhanced roles. To date NorthCentral Provincial Centre and Eastern Provincial Centre have

acquired the necessary land through their respectivegovernment bodies and laid the foundation stones for theirproposed buildings. The Northern Provincial Centre too hasacquired the necessary land in Kilinochchi. Notwithstanding the establishment of permanent buildingsfor provincial centres the need to make IESL servicesaccessible to each and every member is a prime necessity.Thus the concept of IESL District Centres have beenconceived of for districts with significant concentration ofmembers and where there is difficulty to travel to ProvincialCentres. Todate IESL District Centres have been establishedin Kegalle (9/03/2013), Polnnaruwa (14/08/2013) , Mannar(13/09/2013), Ampara (15/09/2013),Batticaloa (15/09/2013)and Monaragala (30/09/2013) districts under their respectiveProvincial Centres.Besides above I want to mention some special events of thesession. In my inaugural address I had mentioned the needto work closely with the IESL NSW (Australia ) Chapter soas to best derive the benefits of international expertise fromdiaspora members of our profession. This, I think, we managedto do successfully as many collaborative activities have beendone with them. Keeping to tradition I attended the AnnualEngineers Convention of the IESL NSW Chapter andparticipated in the Engineering Conference and the GalaDinner that are part of this annual event. I am also grateful toEng.Kamal Fernando, Chairman, NSW Chapter for facilitatingthe first ever meeting between the Presidents of the IESLand the Engineers Australia where I met Dr.Marlene Kanga(National President of Engineers Australia) and the detaileddiscussion on reviews and accreditation processes with Prof.Robin King (EA Chair of Sydney Accord) that followed.

Winning the engineering scholarship forhis performance at the University of London exams held inSri Lanka, he proceeded to join the Downing College, Cam-bridge where he distinguished himself graduating with firstclass honours in Mechanical Sciences Tripos from the Uni-versity of Cambridge in 1931.

Returning to his country of birth he joined the public WorksDepartment serving it for 15 years. He then joined the teach-ing staff of the University of Ceylon in 1946 and was picked tobe the first Dean of the Faculty of Engineering of the Univer-sity of Ceylon when the country decided to educate its engi-neers in its own soil instead of sitting for the London Examsheld at the Ceylon Technical College at Maradana affiliated tothe University of London. Starting from scratch, with borrowedaccommodation and laboratory facilities, yet firm in his stridetowards achieving the best the world could offer at that timeto establish the first Faculty of Engineering in the country..He was appointed the Vice Chancellor of the University ofCeylon Peradeniya in 1969.In 1986 the country honoured himwith the title Vidya Jyothi and passed away in1988.

IESL North Central Provincial Centre HoldsAGM

The Annual General Meeting, 2013 / 2014 session, of the IESL North Central Provincial Centre(NCPC) was held at theGalway Miridiya Lodge Hotel, Anuradhapura, on 12th September, 2013 in the presence of a large gathering of itsmembers, distinguished guests and special invitees. President of the IESL, Eng. Tilak De Silva, President – Elect of

IESL, Eng. Shavindranath Fernando and Chairman ICT Committee of the IESL, Eng. Arjuna Manamperi, graced the occasionwith their presence. In view of the many important initiatives of the last session and the necessity to continue with the greatprogress achieved, office bearers of key positions in the Executive Committee of the last session were unanimously re-elected to serve in those positions in the new session too. Thus an almost unchanged NCPC Executive Committee willcontinue to get the leadership of Eng. J.A.D.R Sujith Kumara as Chairman and Eng. (Ms) D L B P Wijesekera asSecretary to continue their good work in the new session.

The acquiring of a plot of land in Puttalam Road at Korakahawewa, Anuradhapura to build a permanent building of its ownfor the NCPC was an important initiative of the centre in the last session. Preliminary works towards construction of thebuilding have been completed and the foundation stone already laid by the President, Eng. Tilak De Silva, on 31st January,2013. The building is expected to be completed in two stages with the first stage expected to be completed in one year atan estimated cost of Rs 18.5 million. The NCPC is expecting to raise this amount through fund raising. A sum of Rs 1.5million have been already released as donation by the IESL parent body through the special initiative of the President, Eng.Tilak De Silva, towards this endeavor.

The building will be the first such building owned by an IESL Provincial Centre in the island and will be a tremendous boostto the capacity of the NCPC to more effectively perform activities of the centre such as holding meetings, seminars,workshops, etc. towards professional development of IESL membership in the province. This concept is to be extended toall other IESL Provincial Centres as confirmed by Eng. Shavindranath Fernando, the President – Elect of IESL.

Memorial Lecture

A Journey to the pastby Eng. (Mrs.) Badra Kamaladasa,

Irrigation Department

It felt like a journey to thepast when I walked throughthe ancient earth

embankment of“KudaWilachchiya” with agroup of irrigation andarcheology officials. The ruinsof the ancient earthembankment, sluices, spill inthe midst of Wilpattu nationalpark would certainly bring thesame feeling to anyone whovisits there.

Irrigation Department doesthe feasibility investigationsand surveys to restore theancient abandoned reservoirsituated in the South Westof Wilpattu. (Refer map-fig1)Once restored, this will servefor the domestic needs inWilachchiya area, augmentthe irrigation supply to tail endof Maha Wilachchiyascheme, and mostimportantly, it will be aperennial water source to thewild animals in the Wilpattunational park.

This ancient reservoir isbelieved to have been built byKing Wasaba (67-111 AD). Itlies in the thick jungle ofWilpattu national park wherethe public has no access.Hence, those who are doingthe surveys have to travel bya tractor to a certain distanceand lead the rest of thejourney by foot.

Irrigation officials inAnuradhapura believe that,early surveyors would havemixed up the names of thetwo Wilachchiyas, as KudaWilchchiya embankment islarger than MahaWilachchiya. There are 7breaches along the 3 km longembankment. It seems thatthe reservoir had beenbreached due to ahydrological failure, not astructural defect of the sluice(Bisokotuwa), as the twoBisokotuwas and spill areintact.

The well packed rubble rip-rap in the upstream sloperemains undamaged, evenafter .. decades ofabandonment and with themovement of elephant herdsin the park. (See fig 2)Oneother special design featurein the upstream slope is theberm, that provided stabilityto the upstream slope; thisis a rare design concept usedby our ancestors, speciallyfor a high dam section. (seefig3) Massive skilledworkforce would have beeninvolved for the dressedrubble work used in the riprap,as each block has been

Born into a distinguished family of traditional crafts-men, 17th September 1874, the Late Engineer D.J.Wimalasurendra passed away on 10th August 1953 at theage of 79 years. An illustrious son of Sri Lanka whose nameis synonymous with hydroelectricity in Sri Lanka, he is thefirst to conceive the idea of harnessing the waters of thecountry’s rivers for the generation of electricity. It was at atime when the country was facing the unaffordable prospectof having to generate electricity using imported fossil fuel ifit’s to provide the country’s citizens with electricity towardsuplifting their standards of living.

How to Develop Attitudes to makebetter Working Environment

by : Eng. A RanasingheB.sc (Eng), C. Eng, MPA

District Engineer (S.W.), Galle

As we knowE n g i n e e r i n ggenerates many

innovations to the world.Especially where CivilEngineering is concernedthere are various partiesinvolved in constructionprojects, Architects,Engineers, QualitySurveyors, ConstructionEngineers, Technical Staff,Clerical Staff, Minor staffetc.. If we consider onesmall project, it alsoassociates withconsiderable Number ofpeople to make the projecta success. As we areEngineers if we have beengiven an opportunity tohandle a project and achievethe targets in every aspectmay vary from to person toperson. But if we have beengiven complete engineeringeducation we all could havethe same capability tohandle the project to thesame degree as we scoredin the G.C.E. (O/L) Math’spaper. But unfortunately ourmanagement abilities arediffering from person toperson. Here is wheremanagement and attitudedevelopment come into playto overcome suchweakness where humanresource management isconcerned.

Even thoughEngineers are dealing withmassive construction andmanufacturing industriesduring their carrier theyacquire only marginalsubject knowladge ofhuman resourcemanagement during theiracademic stage. But for theachievement of successfulbenefits of engineering it isvery important to learn howto use human capital moreeffectively for the bettermentof engineering. Greaterpercentage of engineeringeducation is based onmathematical concepts. Sothey lack humanities sectoreducation such as artsubjects, literature, music,dramas, critical analysis ofpfychological and socialbehavior of human beingsfor understanding of people.Without properunderstanding of people it isvery difficult to deal withthem and identify their

problems which arise at thegrass root level. Attitudedevelopments of internal andexternal customers are equallyimportant to run anyorganization smoothly.Identification capacities of eachindividuals and getting a job donecan be fruitful only through duerecognition. Every individualsexpect due recognitionirrespective of their hierarchicaland social levels. Attitudinaldevelopment is the way ofrevolutionize a thinking andacting without incurring extrabudget. Some times it may bechanging behavior but totalbenefit of the entire processbenefits both employer &employee.

Developments of anyorganization or country is mainlygoverned by the attitudes of thepeople of such organization orcountry. Attitude developmentmainly depends on economicfactors, religious factors,organizational factors, politicalissues, sub cultural and culturalfactors, educational factors ofboth internal and externalcustomers. But where workingenvironment is concerned it isimportant to maintain degree ofsatisfaction of the customer.Then only the future of suchorganizations could beestablished strongly. Humanbeings are most important andvaluable resources of anyorganization, so it is importantto keep them well aware for thebenefit of both parties.

To adhere to the visionand mission of any organizationis a fundamental requirement ofeach and every employee toenhance the organization in amore productive manner.

Attitude development isdirectly associated with theproductivity. Attitudedevelopment alone does not givebetter solutions for success andit shuold be coupled withknowledge and skill as well. Butattitude development plays adominant role in the humanresource management in bothconstruction and productionsector.

At the recruiting stage ofeach employee, it is essentialto conduct impartial interviewsto select the proper person forthe proper job. If themanagement fails in selectingadequate people for the required

position future of suchorganization is in vain. Toachieve the better result itis required to identify thecapabilities of eachindividual. Not only that,continuous training andmonitoring are equallyimportant factors to buildup better workingenvironment.

Formation ofattitude begin ourchildhood. Parental care,school education, effect ofpeer group association,University education andSocial factors are the mostprominent influences. Endresult of this entireeducation process willturnout people who adhereto the society or may behaving negative ideas ofthe society. So it is achallenge to select morecompetent people withhaving good attitudes.Even though if we recruitpeople with positiveattitude they may changewhen subjected to theassociation of employeeswith negative ideas andthey finally become losersto both organization andthem self.

It's always theemployer’s duty to keephis work place moreproductive and of highstandards of ethics andalso keep his staff happyand reduce their stressesas far as possible whileachieving the organizationgoal. Either bysuppressing theemployees not achievingthe organizational goal thefuture of the entire processmight be at risk. Only thevisionary leader canidentify the real needs ofattitudinal developmentand take necessary stepsto achieve that at any costto benefit the organization.Cooperation with teamwork, communicate openlyand honestly tosubordinates are alsoequally imported factors.Then only team membersof each team will trust theirsuperiors and tend to havehigher job satisfaction.

IESL ENGINEERING EXCELLENCE....

successful efforts towards establishing the MonaragalaDistrict Centre.

Eng. Arjuna Manamperi did a presentation on ‘The Usageand Benefits of the new Membership Management Systemof the IESL’.

Monaragala district being one of the poorest in the country,the government is committed to uplifting the status of thepeople through the Gama Neguma programme whereby eachvillage is to be provided basic facilities like electricity,properroad access, clean drinking water, schools with adequatephysical and human resources, health centres, pre-schools,play grounds, community centres, market centres, etc.

pioneered by the IESL to foster innovation and creativity amongschool children and has become the pathway to larger forumsfor promotion of such talents, the Sri Lanka Science andEngineering Fair (SLSEF) which is held in Sri Lanka and theIntel ISEF held in the USA. Since participating for the first timein 2008 IESL JIY winners have succeeded in winning 08 awardsat the Intel ISEF. This year too one of the winners of the JIY-2012 competition haswon a First Award in the Electrical andMechanical Engineering category at the Intel ISEF 2013 GrandAwards Ceremony held on 17th May 2013 in Phoenix, Arizoan.USA.. Similarly, one of the previous year’s Intel ISEF winnerwho was also the JIY winner had the unique distinction of anewly discovered planet being named after him in recognitionof his win at this international competition which is the world’slargest pre-college science competition fig 6 Paththirippuwa

Inscription at LB sluice

precisely cut to fit theposition.The two Bisokotuwas arealso masterpieces of theancient engineers. Thestone slabs used in theinner face fit each otherperfectly, that there is nospace for plants to grow,even in this thick jungle.(see fig 4) The outer coverof the sluice tower, madeout of bricks, and the innerstone slabs still remainsintact, demonstrating thegreat skills of those ancientreservoir builders.

Another special feature inthe headworks is theconveyance canal from thesluice outlet, which is madeas a close conduit usingstone slabs. (see fig 5)Until the surveys are over,it is difficult to explain thereason for this application.

Its ancient spill is anotherremarkable work of art thatshows the greatengineering capabilities ourancestors possessed.The villagers call the wingwall and the backfillingsection as “Paththirippuwa” since theybelieve it as the placewhere the king had hismeetings (see fig 6).

An inscription at the spillbelongs to 16th centurysays “Kusaya Buduwewa”(meaning- May Kusayaattain Buddhahood)-see fig7

It is proposed to restore theheadworks by preservingancient features with theadvice of The ArcheologicalDepartment. The futuregeneration can observe thespill and sluices built byancient engineers, withoutany alteration.

After spending about threehours in the ancientreservoir premises, I was

stunned, not only with theplanning, design andconstruction capabilities of theancient irrigation engineers butalso with the present irrigationengineers’ struggle, with a bearfamily living in the ancient sluicebarrel and frequently interferingwith the survey team.

It is unfair to label a personsolely based on his or herbehavior. Every person mayhave a tendency to changepresent behavior intocompletely new positivebehavior tomorrow under newguidance and supervision.Depending on the skills of themanagement subordinatescan be motivated to changein the organization. Soleadership plays a vital role.He or she should be capableenough to identify the skilland attitude of employees ofthe organizations. In additionto that, building uptrustworthiness of eachemployer would enhance thefinal goal.

Following steps could berecommended for goodattitudinal development ofhuman being♦ Adhere to theorganization ethics♦ Exercise self disciplineat all times♦ Build up life with strongattitude and positive attitude♦ Regular mental &physical exercise♦ Perform your workwith enthusiasm♦ Listen to others'problem attentively & kindly

♦ Attend to culturalactivities♦ Get rid of badbehavioral pattern♦ Face positively to lifeschallenges♦ Maintain work lifebalance♦ Expand the exposureof your life to more people♦ Share your goodideas with more competentpeople

As a reality we know thateach organizationcomposed with different kindof people. They may differfrom their educational level,capabilities, ideas, politicalback ground, differencebetween have and have-nots. Not only that positionpower of employee it’s selfdoesn’t give any meaningfuldirections to achieve theclear goal without havingsubordinate’s enthusiasm.So it is a some what hardertask by keeping themtogether to achieve samegoal it’s like winning amatch by association withdifferent players with eventattitudes, skills andstrengths in a match bymaximally contributing theireffort win.

memorable and full of funthat even the tourists inthe hotel decided to jointhe traditional biladances!The pioneering spirit ofengineers in the NorthCentral Province wasresponsible for theestablishment of thepredecessor of the IESL,the EngineeringAssociation of Ceylon,the first professionalbody for engineers in SriLanka, established in1906 by a fewGovernment Officersserving in the province.Their current endeavor tobuild the first permanentbuilding of their own byan IESL ProvincialCentre is undoubtedlydone in the same spirit.
