It took 4 years and 1.5 billion dollars to build the highest skyscraper in the world – "Burj Khalifa". The internal square of the building is 350,000 square meters, and the cost of renting one square meter is $900. If the building had been constructed with the new technology, the costs would have reduced by 300 million US dollars (or 20%). In this case it could be possible to make profit (630 million US dollars) from the shorter period of construction by renting (2 years x 900 dollars x 350,000 square meters). The benefit totals 930 million US dollars (almost 1 billion US dollars). A tremendous benefit!
I propose you to develop a new technology.
At first, I wish you continued health and success in future.
The rising land values (especially in big cities) forces developers to increase the number of floors in the building and erect these buildings as quickly as possible. Annual growth of the number of newly built skyscrapers in the world always totals 10% (even in the years of deepest recession). Technologies in different areas of production become more complex, that is why developers have to build all kinds of structures faster and faster.
I propose to develop the technology of “construction (demolition) of the high-rise buildings and facilities (including skyscrapers) without works at height (without tower cranes and work platforms)”. Main elevating (for construction) or depressing (for demolition) works are making at the first-floor level of a building or a facility (including skyscrapers). Under such a condition the need of using of tower cranes (working platforms) is eliminated, and special new technology hoisting mechanisms are used for elevation (depression) of buildings and facilities.
The time required for construction (demolition) of buildings and facilities (including skyscrapers) with the using of new technology is halved compared with the traditional technology. See the calculation attached.
The cost of building and construction works is reduced by 20 – 25%. There are also other considerable benefits.
There is no other similar technology around the world. This means that our product is unique and exclusive on the market, so we can make a fair profit.
Commodity market for the equipment is the world construction (demolition) market of high-rise buildings and facilities (including skyscrapers). Today such buildings are constructed with using of tower cranes (working platforms). The effectiveness of the new technology will allow to replace production and sales of tower cranes (working platforms) for production and sales of the new technology hoisting machinery.
According to expert assessment, the total revenue of the world’s largest manufacturers of tower cranes exceeded 30 billion US dollars in 2014, and the annual growth is estimated at 3 – 5% (Work Materials. EURASIAN ECONOMIC COMMISSION.).
Referring to the possible product sales revenue, of course it will be the amount much bigger, than the sales revenue of tower cranes (working platforms), which are now used for high-rise buildings’ construction.
The following is necessary for sustainable development and project monetization of the new technology:
Traditional construction technology New construction technology
Тct = Тmh + Тse; Тct = 2Тse; Тnt = Тse + Тbe; Тnt = Тse;
where Тct – construction time for one storey of a building according to traditional technology;
Тmh – time for handling of materials, structures for erection of one storey;
Тse – time used for erection of one storey of the building;
Тbe – time for elevation of a building, using the new technology (supposedly 1,0 - 2,0 hours);
Тmh = Тse, as according to traditional technology, material and structures handling for erection of one storey, and storey erection starts and terminates at the same time.
It is supposed that elevation (depression) of a building shall take 1,0 – 2,0 hours, and comparing to erection of one storey of a building it is a “rapid time period”, besides during erection using the new technology the amount of installation and de-installation works for the cast forms of particular structures, that is why in the estimation data Тbe = 0.
That is why it is necessary to agree, that Тnt = 0,5Тct.
Please pay attention that the estimation data strongly indicates that traditional construction technology shall never “overtake” the new technology by duration of the period of construction, no matter how many tower cranes it uses for construction of one or another highriser.
