Mashhad – IRNA – The head of the specialized civil engineering department of Khorasan Construction Engineering System Organization Razavi said: Many constructions, especially contract buildings in Mashhad, are built in different ways without the supervision of construction engineers.
Javad Maruti added on Monday in a press conference about the conference of a new look at concrete structures with a durable and reliable approach: Doctors are now among the builders and sellers of Mashhad, and if we measure the contribution of those who participate in construction in terms of riyals, they are the least. Engineers have the share.
He continued: The entry of non-specialists into the field of construction is the main reason for the short life of buildings, and if the level of precision in the construction of a building increases, a high-quality structure can be built, either metal or concrete.
A member of Khorasan Construction Engineering System Organization, Razavi said: In advanced and industrialized countries, the monitoring system is such that non-specialists are not allowed to enter the field of construction, let alone be the main trustee in construction.
He added: the useful life of buildings in the country is very low and between 20 and 30 years, so that a 20 to 25-year-old building is considered a dilapidated unit and needs to be demolished, while this action is a waste of national funds.
Maruti continued: This is despite the fact that a 20-year-old building in industrialized and advanced countries looks like a young building, and its minimum useful life is 100 years, and 150-year-old buildings are also used in those countries.
He said: Concrete is the most widely used building material in the world after water. Based on the statistics of issued building permits, between 65 and 70 percent of buildings in industrialized countries and about 65 percent of buildings in Iran are made of concrete, but this figure is about 6 percent in Razavi Khorasan and The rest of the buildings in this province have a metal frame.
The head of the specialized civil department of the Khorasan Building Engineering System Organization, Razavi added: Concrete buildings are better than buildings with a metal frame in terms of life and durability, because metal has a lot of corrosion and even corrosion in concrete is related to its metal reinforcements.
He continued: the cost of using concrete structures is between 20 and 30% cheaper than metal structures, on the other hand, Razavi Khorasan, especially Mashhad, is the hub of cement production and production units in this field, which can provide concrete at a lower cost to building builders. .
Maruti said: While Isfahan is a hub for steel production, the number of concrete buildings in this province is higher than the national average, and about 90% of buildings in Isfahan province are concrete.
A member of the Khorasan Construction Engineering Organization, Razavi added: The life of the building depends on the environmental conditions of each region and it is not possible to mention a number in this field. In areas with humid climates such as the north and south of the country, the number of metal buildings is almost zero because concrete is more durable than metal. has it.
He continued: Since one of the main reasons for the small percentage of concrete constructions in Razavi Khorasan is cultural and educational weakness, the conference of a new look at concrete structures with a durability and reliability approach, with the presence of experts and the cooperation of Mashhad Municipality, will be held in this city on December 21. will be held.
Maruti said: This conference will be held with the presence of 200 engineers in four fields, and Dr. Homayoun Abrishmi, a visiting professor from Canada, and Professor Ali Akbar Ramzanianpour, the father of Beton Iran, are the main speakers of this conference.
