Building that collapsed in Kandy on Sunday

There is no need to elaborate that the collapse of buildings or any other structure will result in very grave consequences. It may lead to loss of life and serious injuries not only for the occupants but to the neighbours and the people around when the collapse happens. These will be in addition to the loss of valuable physical assets and further legal claims.

We frequently hear about building failures in crowded cities across the world. However, until recent times there were not many building failures reported in Sri Lanka. It is possible that the main reasons were, (a) No major loss of life (b) Mostly of the buildings in the country were low rise structures (c) Building failures do not catch the eyes of the media.

It is common knowledge that the failures of buildings are mainly due to

(a) Inadequacy in the structural design and the unsuitable ground conditions

(b) Serious shortcomings in the construction phase

(c) Upgrading of existing buildings such as construction of additional floors without proper engineering assessment.

In Sri Lanka, during the last decade the construction activity had been moving on a rapid phase. We could note that many new buildings with multiple stories being built in practically all the towns and along major roads. Now there is also news that the plans are afoot to build a tower block in Colombo that will be the world’s tallest.

Unless these buildings are designed and detailed by competent engineers, and built under their supervision, we could expect many non-compliances to the relevant structural engineering. standards. Non-compliances may result in failures during the construction phase as well as during the occupation. To prevent such man-made disasters, it is imperative that the roles of the government and the local authorities who approve the projects need to be strengthened.

The construction of a building will go through two stages, i. e. design phase and construction phase. As I understand, at present the local authorities in urban areas need to approve the design documents and issue a building permit to allow construction phase of a building. In this process, if the plans submitted involve a specific engineering design, it is mandatory for a Chartered Civil or a Structural to sign and approve the plans.

Here the questions that will arise,

Whether the local authority has access to the register of chartered civil / structural engineers maintained by the Institution of Engineers, Sri Lanka?

Are the chartered engineers who sign the plans experienced in the type of structural design, to allow him to vet and approve?

What will be the responsibility of the structural engineer if the building fails during or after construction?

As I am aware, in the present system, the engineer who designed the building could become responsible only if it could be determined through a lengthy legal process. As we know, such process will be too arduous and there will be many loop-holes that will permit an unscrupulous person to shun the responsibility.

In many countries, there are built in regulations to prevent such failures in all the stages of a project, including investigation, design, construction and maintenance phase.

These rules impose the total responsibility for the design to the design engineer. To make the process transparent, the design engineer issues a Design Certificate or a Producer Statement identifying all the relevant design standards. It is mandatory for the design engineer to have an insurance policy for his professional works. The purpose of this policy is to indemnify the owner of the building if any failure happens. Generally the Producer statements are in a format approved by the local institution of engineers in the country. Council can approve the building applications only on vetting the acceptability of the said documents.

Such process needs national regulations that will clearly cover all the stages of the building permit process and identify the responsibilities of the relevant parties. I believe that the UDA shall take the responsibility of drafting the regulations on this issue that is very critical to the country. The Institution of Engineer Sri Lanka will also have a role to play to make sure that the engineer who signs the design documents will take the total responsibility for the design.

As notedd earlier the failure of a building may be the result of noncompliance to the engineering standards in the construction stage. It may be due to the wrong selection of materials or the adoption of erroneous methodology. Simple examples are the use of low grade steel reinforcements or using weak structural concrete, or untreated low-grade timber.

 

It may also be due to the adoption of inappropriate technology or using short cuts during the construction stage. There are many examples in Sri Lanka where the wrong methodology used in construction will result in serious inadequacies and failures during the usage. One example I could recall is the leakage from concrete walls and basement floor in a mid-rise building built in Rajagiriya for a very important organization in the country. It was found that the concreting in the basement walls went ahead although the poker vibrators broke down in the middle of the process. Here the construction was carried out by a prime structural engineering contractor, but without adequate supervision by the consulting engineer.

It is not exaggeration that the specifically designed structural works need to be supervised by a qualified engineer who very well understands the design methodology and the controls needed in the construction stage. However, there is no mandatory requirement under the building approval conditions in Sri Lanka that the building owner needs to obtain the services of the design engineer. Therefore, the design engineer’s involvement in the construction phase will depend on the contractor or the owner that will be mainly decided by the financial implications. Such decisions may affect the compliance to the design standards in the construction phase. If the structure fails during or in the post construction stage, the design engineer cannot be held responsible as he had not been involved during construction. Therefore, the need arises to impose conditions under the building approval to obtain the services of the design engineer or another chartered engineer to supervise the construction phase and to certify. In many countries, this is facilitated by the need for the supervising engineer to issue a certificate such as a Producer Statement – Construction at the completion of the construction phase. In the format, this is similar to Certificate issued to the cover the design but will only cover the construction stage. Naturally the issuer of the Producer Statement – Construction needs to carry an insurance policy that will cover the value of the structural works in the building in indemnify the owner in the event of a building failure.

Finally, it needs to be noted that all the matters discussed above are relevant to any built-up structure, whether it is a building, highway bridge, water reservoir, tunnel or an irrigation dam. I hope that this column will attract serious attention from the engineering profession as well as the central government and local authorities who will have to face the consequences when the structures fail.

US’ anti-migrant stance set to intensify tensions in Western camp

Published

on

The announcement by the US authorities of an anti-migrant stance during a recent commemoration in France of the epochal D-Day Landings of June 6, 1944, ought to strike impartial observers as a supreme irony. Whereas what should have been expected was a vibrant celebration of the beginning of the process of Western Europe freeing itself decisively from Nazi or fascist control during the crucial stages of World War Two, this was not to be.

What the world heard instead was a call to contemporary Western Europe to arm itself against a seemingly rising and threatening migrant presence in the region. In other words, the migrant must be despised and ‘shown the door’.

Instead of a commemoration that rejoiced in the flourishing of liberal democracy and its values what one got was a strong affirmation of fascism and racial chauvinism. US Defense Secretary Pete Hegseth vented his spleen against the migrant or foreigner presence in Europe reportedly thus: ‘Sadly today different European beaches are stormed by different dangerous ideologies.’ To ‘beaches in Spain and Italy and Greece and Bulgaria, boats and men arrive. When will European capitals do something about that invasion?’

While at the outbreak of World War Two it was Nazi Germany that was doing the invading and bringing some principal European countries under its suzerainty, this time around we are being given to understand that it’s migrants to the West who are seeking to colonize the latter. It goes without saying that such inflammatory rhetoric would have the deleterious effect of keeping racial tensions alive in the West and jeopardize all possibilities of the countries concerned cementing and maintaining social stability.

The Trump administration gives the impression of taking a leaf from the politically underdeveloped regions of the South to keep the US polity stable and united. In South Asia, for instance, we are not short of ambitious demagogues who use what is referred to as the ‘race card’ to gather unto themselves a following and thereby further their political fortunes. By seeking to stir and sustain anti-migrant hysteria, the Trump administration is also essentially replicating Nazi Germany’s policy of anti-Semitism. That is, fascism is very much alive in the US under President Trump.

Such efforts at churning racial hysteria at this juncture in the US should not come as a surprise. For all intents and purposes, the Trump administration is nowhere near achieving its aims in West Asia, for instance, in the short term. It has failed to bring Iran down to its knees, as it hoped to do, but is adopting the expedient of keeping the world guessing and confused on what it is doing in the region, since it cannot withdraw from the theatre in a hurry without losing face.

While perhaps working out an escape strategy the Trump administration it seems, is hoping to maintain its following at home intact and silent by playing on their racial biases and insecurities. Hence, the anti-foreigner campaign.

Simultaneously, the Trump administration will need to keep a close eye on how economic pressures on the domestic front are panning out. Anti-administration sentiments first break to the surface at meal tables. On this score, the news cannot be good because the average US family’s spending power ought to be shrinking on account of rising energy and oil prices. Consequently, it would not be a bad idea to keep the attention of the US consumer diverted by adeptly playing ‘the race card’; once again, lessons from intellectually bankrupt Southern politicians are coming in handy.

To be sure such comparisons many politicians in vibrantly democratic countries would find quite unflattering. But the stark truth is that racism cannot be tolerated in civilized societies and those politicians who resort to it risk being branded as racists of the first degree. In fact they could be seen as being on par with the likes of German dictator Adolph Hitler and his close collaborators.

However, on the question of migrant policy the Trump administration would likely be at polar opposites with the most vibrant of liberal democracies of the West. This will be the case with the UK, France and Italy for instance. The latter continue to keep their doors open to legal migrants and they are likely to view a virtual blanket ban on migrants as reprehensible.

Moreover, in the foremost democracies of the West debates are vibrantly ongoing on the need to keep racism or any hint of it completely outlawed in the public plane. There is the case of the UK, for instance, where the authorities continue to emphatically pinpoint their adherence to the principle of anti-racism in the conduct of public affairs.

One proof of the above was the parliamentary debate relating to the killing of 18-year-old Henry Nowak in Southampton. Police handling of the victim came in for sharp scrutiny by particularly the opposition in the House of Commons but there seemed to be a consensus over the main political divide that the matter should not be politicized.

Moreover, the UK authorities stressed in the House the government’s strict adherence to the policy of non-racism. It was also pointed out that British institutions set up to manage racism at the national, county and neighbourhood levels, for example, were very much intact. In fact, Sri Lanka could gain considerably by studying and implementing locally, legislation modeled on the relevant UK laws if it is in earnest when it speaks of ‘reconciliation’.

Accordingly, it is highly unlikely that Western Europe would ‘cave in’, so to speak, to US pressure on issues related to migration. The liberal democracies of Western Europe in particular would remain for the foreseeable future migrant-welcoming, multi-ethnic and plural democracies.

Nor is it likely that Western Europe would be passively receptive to US demands that it drastically increases its defense spending to meet the latter’s demands. Within the Western fold the EU is remaining committed to backing Ukraine, for instance, in its ongoing armed resistance to the Russian invasion and it is not giving any indication of being deferent to US pressure.

However, although tensions would continue to bristle within US-Western Europe relations on the above and numerous other matters of contention it would be far too premature to announce a parting of company between the two sections of the West. In that sense, the post-World War Two order remains essentially intact. There are still many things in common between the two, particular on the economic plane, that will ensure the continuance of the partnership.

A decade among Yala’s ghosts of gold

Published

on

YM75 "James" surveys his territory from a tree-top vantage point, demonstrating the leopard's commanding presence in the landscape.

The first rays of dawn creep over the ancient rocks of Yala. The Indian Ocean glimmers in the distance, and the wilderness slowly awakens. Somewhere amid the scrub jungle, a pair of amber eyes scans the landscape.

For wildlife conservationist and leopard researcher Milinda Wattegedara, moments such as these have defined more than a decade of dedication to one of Sri Lanka’s most iconic creatures—the Sri Lankan leopard.

What began as fascination evolved into a remarkable conservation journey that has transformed the understanding of Yala’s leopard population and placed Sri Lanka firmly on the global wildlife research map.

“Long before I ever lifted a camera, leopards had already captured my imagination,” says Wattegedara. “What fascinated me was not merely their beauty but the complexity of their lives—their hunting strategies, movements, reproductive behaviour and their remarkable ability to adapt to changing environments.”

That fascination led to the birth of the Yala Leopard Diary in 2013, an ambitious long-term project dedicated to documenting individual leopards and unraveling the mysteries surrounding their lives.

For many visitors, a leopard sighting is a fleeting thrill. For Wattegedara and his team, every encounter is a chapter in an ongoing scientific story.

“Each photograph was never the end of an encounter,” he explains. “It was the beginning of deeper questions. How did a particular leopard use the landscape? How did its behaviour change with the seasons? What environmental pressures shaped its decisions?”

These questions drove years of meticulous fieldwork. Every sighting was carefully recorded with details including location, habitat, behaviour, date and time. Photographs were analysed to identify individual animals through unique spot patterns, allowing researchers to distinguish one leopard from another with remarkable accuracy.

What followed was groundbreaking.

YF77 “Shelly” pauses in quiet observation, embodying the alertness
and grace that define Yala’s leopard population.

From 2013 to 2026, the Yala Leopard Diary identified an astonishing 189 individual leopards within the Yala Block 1. The research revealed a leopard density of approximately 0.524 leopards per square kilometre, making Yala one of the highest leopard-density landscapes ever recorded anywhere in the world.

Such findings have elevated Yala’s status among global wildlife researchers.

Nestled between the Indian Ocean and a mosaic of habitats, ranging from rocky outcrops to dense scrub forests, Yala offers an ecological stage unlike any other.

Here, leopards are photographed silhouetted against ocean horizons, perched atop ancient granite formations, resting on tree branches and stalking prey across sunlit grasslands.

The images tell stories of extraordinary lives.

There is Haminee, a devoted mother navigating the challenges of raising cubs in a competitive landscape. There is Lucas, one of Yala’s most frequently documented males, striding confidently across the Gonalabba Plains with the vast ocean forming an unforgettable backdrop.

There is Ruki demonstrating the species’ incredible strength by hoisting prey onto branches, and Shelly, quietly surveying her surroundings in a moment of feline vigilance.

Together, these individuals have become familiar characters in a living wilderness drama.

Recognising the immense value of long-term documentation, Wattegedara joined forces with fellow researchers Dushyantha Silva, Raveendra Siriwardana and Mevan Piyasena to establish the Yala Leopard Centre in 2020.

Located at the Palatupana entrance to the Yala National Park, the centre is believed to be the world’s first information facility dedicated exclusively to leopards.

“The centre serves as a repository of knowledge, accumulated through years of observation and research,” Wattegedara says. “Our goal is to connect visitors with the science behind conservation and foster a deeper appreciation of these magnificent animals.”

The project’s impact extends far beyond Sri Lanka’s borders.

Research arising from the Yala Leopard Diary has been published in internationally recognised scientific journals. One study introduced an innovative framework for identifying individual leopards, while another documented an extraordinary and previously unrecorded case of a leopard cub being consecutively adopted by two different adult females—first a relative and later an unrelated leopardess.

The discovery attracted international scientific attention and highlighted the complexity of leopard social behaviour.

Yet for Wattegedara, the most important lesson remains one of humility.

“One conclusion has become increasingly clear,” he reflects. “Our understanding of these leopards remains far from complete. We are only beginning to understand how they live, adapt and persist in one of Sri Lanka’s most dynamic protected landscapes.”

YF15 “Hope” descends Rukvila Rock at dawn, showcasing the agility and adaptability of Yala’s leopards.

His words underscore an essential conservation truth: the more we learn about nature, the more mysteries emerge.

As Sri Lanka navigates growing environmental challenges, the Yala Leopard Diary stands as a shining example of what sustained observation, scientific curiosity and public engagement can achieve.

Beyond the stunning photographs and remarkable sightings lies something even more valuable—a growing body of knowledge capable of informing future conservation decisions and ensuring that future generations inherit a wilderness where leopards continue to roam free.

For more than a decade, Wattegedara and his colleagues have followed the tracks of Yala’s elusive predators through dust, rain and scorching heat.

Their work has revealed that every leopard has a story, every sighting has significance and every photograph can contribute to conservation.

And perhaps, most importantly, it has reminded us that the golden ghosts of Yala still have many secrets left to share.
