MODERN Trends in Construction and Building

Emerging technologies and construction practices will transform the construction industry and lead to projects that are faster, safer and less expensive. From cutting-edge building technologies to innovative construction methods and better decision-making systems, projects are getting smarter. Given the rapid development of emerging construction opportunities, owners should demand faster projects, lower costs and better buildings. Here are some trends that will shape and improve construction projects in future and beyond. 1. Detailed 3D BIM modeling  Instead of 2D drawings, 3D computer designs using Building Information Modeling (BIM) are becoming the standard, providing owners better visualizations. And these go for both architectural and building systems. Design consultants use BIM to model structural engineering, mechanical, electrical and plumbing systems, ductwork, steel work and more. Combined with clash detection programs, designers can ensure no systems interfere with ...

INFRASTUCTURAL RACE: CHINA A CHEETAH ; INDIA A SQUIRREL

Don’t you find it odd when you read headlines in the newspaper which says china builds a nineteen storey building within 36 hours or a replace a bridge within 43 hours while in India even a project as minute as covering of drains in the city takes over two years or completion of a fly-over in four years! One of the amazing things in China is how fast everything gets built. If we did things this way in India, we would have high speed rail connecting every town and subways underneath every city.  I tried to dig in and find about the lapses present in India and why china is so ahead of us in this race while even though both the countries nearly have the same population.  ADVANTAGES DISPUTE OVER LAND The first thing to build any structure is a need for land. That’s the first step towards building one. And the Chinese have a huge advantage of not worrying about the process. The state or better the central authority owns all the land and hence all the legal p...

Move over, Superman! New method sees through concrete to detect early stage corrosion

When you undergo a fall or  undergo some  other traumatic blow, the first thing the doctor will do is take an X-ray, CT scan or MRI to determine if anything has been damaged internally. Researchers at the National Institute of Standards and Technology (NIST) are using the same principle, but in a more powerful form, to detect corrosion, the primary danger threatening the strength of the steel framework within the nation's bridges, highways and other aging physical infrastructure. A non-invasive  "spectral fingerprint" technique that reveals the corrosion of concrete-encased steel before it can cause any significant degradation of the structure it supports. current  imaging methods for uncovering corrosion use microwaves to record changes in the physical state of the affected steel, such as changes in the thickness of a rebar within the concrete of a bridge or other structure. that's a real problem since the average age of the 400,000 steel-reinforced concrete br...

SELF-HEALING OF CONCRETE BY BACTERIAL MINERAL PRECIPITATION

Image
                                            -By Sanket Jain Although concrete is the world’s most used building material, it has a serious flaw: it can easily  crack when under tension. If these cracks become too large, they will lead to corrosion of the steel reinforcement, which not only results in an unattractive appearance, but also jeopardizes the structure’s mechanical qualities. That is why engineers often use a larger than the necessary amount of steel reinforcement within a concrete structure in order to prevent the cracks from becoming too large. This extra steel has no structural use and is an expensive solution as steel prices are high. Another way to deal with cracks is to repair them. The ultimate solution would be self-healing concrete, which is exactly what TU Delft researchers are working on. By embedding calcite-precipitating bac...
CIVIL STUDENTS SOCIETY BITS, Pilani AAC BLOCKS THE NEW RED BRICKS IN INDIA Civil engineering is one branch which will never get old because housing and infrastructure will always remain the top priority for the mankind anywhere. And so arises the necessity to keep it advancing with newer technology and easier means to sustain it. In this article I would like to introduce to the readers a building block which has now started replacing the conventional red bricks that have been in use for the time memorial. I am certain not many have heard of the ACC or AAC blocks that have come up recently in India to build malls or institutes. In my recent visit to a site in the central Delhi, where India’s largest police headquarters are being made i got to know about this alien material which will stand as high as 17 floors along with two floor basement.  Though AAC was introduced to the world in 1932 in Sweden however the Indians have got this in use in the 21st century. There are immense ...
