At present, the Kingdom\u2019s construction sector has risen remarkably, especially high-rise, residential projects. But experts says that a lot of engineers have yet to think about putting in measures to protect against natural disasters. Some are thinking only of basic safety measures while earthquake safety measures have been added only to an unconfirmed number of\u00a0 high-rise buildings.<\/p>\n
According to the latest report from the Ministry of Land Management, Urban Planning and Construction, in 2019, there were 4,446 construction projects in the country, totalling 18,540,879 square meters (sq m), with an estimated investment of $9.3 billion, up 78.88percent\u00a0 compared with the same period last year and involving estimated investment capital of $5.22 billion.<\/p>\n
In 2019, there were 432 high-rise buildings. There are 436 buildings of five floors and up (Sihanoukville has 203 high-rise buildings). Of these, 208\u00a0 have five to nine floors, 135 have 10 to 19 floors, 57 have 20 to 29 floors, 23 have 30 to 39 floors and 13 buildings are 40 floors up or more.<\/p>\n
In particular, there are 3,732 housing projects \u2013 38,488 units. There are 40 Borey projects in the country \u2013 16,589 houses or units, with a total floor area of 2, 496,358 sq m. In addition to that, there are 20,781 apartments or villas across the country and 152 condominium projects with 17,707 apartments.<\/p>\n

Questions over safety<\/strong><\/p>\n <\/p>\n \u201cSo far I am not sure whether all construction and buildings in Cambodia have included\u00a0 earthquake safety measures or not. But I think if they are just residential projects, they may not put this measure in their basement or foundations of the buildings and housing,\u201d said Professor Sieng Peou, a lecturer at the Institute of Technology of Cambodia.<\/p>\n Sieng adds that 30 to 40 high-rise buildings have already included the earthquake safety measures in the construction. However, he says residential projects or housing projects may not have the safeguards.<\/p>\n \u201cI believe they will add earthquake safety measures into the calculation before they start\u00a0 construction,\u201d Sieng adds. \u201cHowever, what I am concerned about is the housing or residential projects because they have not thought about it or they think about the extra cost of the construction. Also, they note that Cambodia has never encountered such a disaster,\u201d he added.<\/p>\n Sieng says the earthquakes in Laos was not too serious and there was not much damage because the majority of the buildings in Laos and Thailand possess earthquake safety measures.<\/p>\n <\/p>\n Total destruction<\/strong><\/p>\n <\/p>\n An earthquake measuring magnitude 5 to 6 will make the furniture move if safety measures are in place. Without them, building may suffer just small cracks. But when it comes to magnitude 6 to 7, some buildings will collapse, while at magnitude 7 to 8, many buildings will be destroyed. From magnitude 8 and above, there will be totally destruction of buildings, bridges and roads.<\/p>\n Some earthquakes may appear to happen but they may be the effects of passing heavy trucks that makes buildings vibrate or from the use of pile drivers in construction.<\/p>\n \u201cAt present, we use software or other technology to measure earthquake effects for every high-rise building,\u201d Mr Sieng says. \u201cHowever, not every house owner wants it.<\/p>\n \u201cAt present, some house owners claim that they are better than engineers and they do not believe in us [engineers]. They always think things will be fine. Generally, if the situation remains as it is in Cambodia, it is fine. However, the location of quakes can change day by day. If it is moving to the sea, it will affect Vietnam or other areas close to the sea. However if it is moving on land, it will impact us and we will not know in advance.\u201d<\/p>\n Sieng explains that if the heat of the earth increases a lot, there will be quakes all over the place. However, he adds that where the tectonic plates of the earth are thick and firm as in Cambodia, there will not be any quakes.<\/p>\n Lack of measures<\/strong><\/p>\n <\/p>\n Chrek Soknim, president of the Cambodian Valuers and Estate Agents Association, says some developed countries have strong buildings and the technology to measure or warn about an impending earthquake. \u201cThey build buildings that can move or are otherwise resilient to natural disasters such as earthquakes,\u201d he said.<\/p>\n \u201cMost of our building engineers have yet calculated an earthquake effect on buildings. Because we have never experienced an earthquake, we do calculate other safety concerns only.<\/p>\n \u201cWhen they think about climate change, they will add more measures or calculations to increase safety. We do not think about it yet. The high-rise buildings already built are meant to last 50 years.\u201d<\/p>\n Chin Hok, chief executive officer of Diamond Island Development Co Ltd, said some buildings and new projects in his development areas have already installed earthquake safety measures in their constructions because these investments are from foreign countries.<\/p>\n Chin adds that the high-rise building engineers have already thought about the possibility of earthquakes. However, the residential developers have yet to think about this. \u201cSome high-rise building in Koh Pich (in Phnom Penh) were developed by foreign investors, so they have thought about this. However, as for the villa and residential projects, we do not know.\u201d<\/p>\n Chin adds the new project of Phnom Penh International Airport has included earthquake safety measures. While, some new buildings in Koh Pich have also added them.<\/p>\n Cambodian tycoon Pung Keav Se, chairman of Overseas Cambodia Investment Corp and president of Cambodia Constructor Association (CCA) says that all the projects in Cambodia, especially the high-rise building have been designed to be compliant with earthquakes of magnitude 7, which has never occurred yet in Cambodia.<\/p>\n <\/p>\n \u2018A bit of anxiety\u2019<\/strong><\/p>\n <\/p>\n \u201cWe were influenced by neighbouring Vietnam many years ago and it caused a bit of anxiety in Phnom Penh,\u201d Pung added. \u201cOur designers are of the highest level to do these jobs. I\u2019m not much concerned [about it].<\/p>\n \u201cNormally the architect must think about risks such as floods, storms and earthquakes, so we do protect buildings but we are not worried.<\/p>\n \u201cWe do not know what the effects of climate change will be, so we do not know about the futurebecause each year temperatures rise more than 1 degree Celsius. We do not know the influence of this on Cambodia, but we are already protected so we do not worry.\u201d<\/p>\n <\/p>\n Safety costs cash<\/strong><\/p>\n <\/p>\n Dr Tan Monivann, vice-chairman of the Cambodia Chamber of Commerce, said: \u201cI don\u2019t think a lot of our construction and building experts in Cambodia have yet thought about the possibility of earthquakes.\u201d<\/p>\n Tann adds that the engineers thought of or calculated only about other safety measures for\u00a0 buildings.<\/p>\n \u201cIt depends on the budget and funding to implement it because it will cost a lot of money for each building owner to put the earthquake safety measures in.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":" Some developers have funded systems to cope with quakes but others have failed to do so because the Kingdom has yet to experience a catastrophic shift in tectonic plates, unlike others<\/p>\n","protected":false},"author":3,"featured_media":3329,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_mi_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_FSMCFIC_featured_image_caption":"A new building goes up in Cambodia but it isn\u2019t necessarily resistant to a big earthquake","_FSMCFIC_featured_image_nocaption":null,"_FSMCFIC_featured_image_hide":null,"footnotes":""},"categories":[257],"tags":[717,347],"yoast_head":"\n![\"\"](\"https:\/\/capitalcambodia.com\/wp-content\/uploads\/2019\/12\/Page-12-1.jpg\")
