Top 10 innovative constructions


Daily “The Telegraph” compiled a top of the most innovative buildings in the world, selected upon architecture and materials used for construction. 

#10-Ripleys Believe it or Not Museum (Ontario, Canada)

The Believe it or Not franchise showcases curiosities in a number of locations, however, the design of the museum at Niagara Falls Ontario deserves to make the exhibition itself. The building represents an upended skyscraper on its side that has taken some of the road with it, as a taxi floats inexplicably and pedestrians and construction workers cling on.
#9-Piano House (Huainan, China)

 Music-lovers of Huainan, China, can revel in this building, designed by architecture students from the Hefei University of Technology. The focal transparent violin contains the escalators and the staircase for the main piano-shaped building which is currently used to by city planners to display plans and proposed developments.                           

#8-CyberTecture Egg Building (Mumbai, India)

 Designed by James Law, Cybertecture International and engineer Ove Arup, the “egg” houses 33,000 sqm of office space in 13 storeys, achieving this using around 15 percent less area than a conventional building of this size. The structure supports floor plates without the need for obstructive columns.
The building achieves sustainability and energy efficiency through its passive solar design, the inclusion of an elevated garden which aids in cooling the interior through thermolysis, use of photovoltaic panels and wind turbines on the roof, and the facility to recycle sullage.
#7-The Basket Building (Ohio, United States)


The headquarters of the Longaberger Basket Company serve as a striking advertisement for its wares, albeit 160 times larger at 192 feet long by 126 feet wide. Completed in 1997, the seven-storey ‘basket’ features handles that can be heated during cold weather to avoid ice damage.
#6-Kansas City Public Library (Missouri, United States)


The ‘Community Bookshelf’ of Kansas Library’s Central Parking garage features 22 popular and varied titles reaching a height of some 26 feet, which were chosen by literature fans of the city. They serve both as a reminder of the public’s favourite books and an attractive disguise for the car park behind that was built to satisfy demand in 2006.                
#5-The Shard (London, England)


Modelled on a shard of glass, Europe’s current tallest building at 306 metres was constructed in three years. It consists of 72 floors, the uppermost of which houses an open-air observation deck. It dominates the London skyline and is a popular tourist attraction.           
#4-HARPA Concert Hall and Conference Center (Reykjavik, Iceland)


The award-winning design by artist Olafur Eliasson with Henning Larsen architects was influenced by Iceland’s renowned natural scenery and the Northern Lights, and in its waterfront location, dramatically reflects both the sky and harbour in its glass façade. LED’s illuminate at night to produce a truly stunning landmark.
#3-Linked Hybrid (Beijing, China)


Constructed by Steven Holl Architects between 2003 and 2009, the 220,000 sqm mixed-use complex consists of eight connected towers. The architect says the design was intended “to counter the current privatised urban developments in China by creating a new twenty-first century porous urban space, inviting and open to the public from every side.”
#2-Shenzhen Baoan International Airport - Terminal 3 (Huangtian, China)


The recently completed 1.5km, 500,000 sqm terminal is a striking visual from above and was designed by architects Massimiliano and Doriana Fuksas to resemble a manta ray. Honeycomb shaped panels punctuate the roof, allowing natural light to filter through.
The distinctive white conical columns rise to touch the roof at heights of up to 80 metres. Air conditioning vents are enclosed within stylised ‘white trees’. Shenzhen Airport Group was so pleased with the design that it is attempting to copyright it.
#1-Metropol Parasol (Seville, Spain)


Designed by the German architect Jürgen Mayer-Hermann, who won a competition for ideas to redevelop the site, the Parasol overcame construction difficulties that saw it more than double in cost to €100m after six years of work and a redesign.
The Metropol Parasol has revitalised the Plaza de la Encarnación, which was for years reduced to being used as a parking lot and gained a reputation as a dead zone between the city’s popular tourist attractions.
The structure consists of six large mushroom-shaped parasols which provide shade from the city’s often hot climate and stands some 90 feet high and nearly 500 feet long. To avoid disturbing the Roman Ruins in the area, supporting columns could only be placed in certain locations, requiring an unusual design.

Bucharest, Pitesti and Slatina top the cities with most accessible apartment prices



Residential complex Maresal Averescu superstructure
One year from launching the financing version in lei of „Prima Casă“ programme, the accessibility of dwellings in Romania has visibly improved, while the prices have remained constant, Capital writes. The daily newspaper compiled a top of the cities with most accessible prices.

In determining the accessibility degree of a dwelling financed by loan, three variables must be analyzed:  value of the dwelling, loan cost (monthly installment) and level of revenues (to set the ratio of the installment within the revenues – the indebtedness).

Residential complex Maresal Averescu superstructure
In the first half of this year, the top of cities that provide access to the lowest indebtedness for the acquisition of a two room apartment has changed. At the moment, Piteşti, Bucharest, Slatina, Târgu-Jiu and Sfântu Gheorghe top the city ranking, while six months ago Alexandria, Sfântu Gheorghe, Slatina, Reşiţa and Bucharest ranked on the first five positions. 

The change was mainly triggered by the wage fluctuation and in some situations by the adjustment of the average transaction prices.  Piteşti and Bucharest have been the most dynamic cities in this period, climbing from the 6th and 5th positions to the top of the ranking. Today, the average Bucharest earner can easily realize that the 244 euro/month installment that he or she has to pay for an old two room apartment is under the level of rents demanded by owners for the same type of dwelling, the acquisition of an apartment being more advantageous.  

Residential complex Maresal Averescu
The dwelling price annual wage ratio is placing Bucharest on the 10th position, while Sfantu Gheorghe, where the index is 6.3, ranks first.

On the opposite side, Oradea, Suceava, Buzău, Focşani and Vaslui are the cities where indebtedness is the highest in the country. In these cities the prices have stabilized at a relatively high level and the income has not recovered the difference.  For instance, the average price per sqm of an old apartment in Oradea is 16% lower than in Bucharest, but the average wage is half of Bucharest average wage.

National priceshave dropped significantly from mid- 2008 until today. Old buildings have registered a decline of approximately 40% and the prices of new apartments have dropped 33%.

Residential complex Titeica
What is interesting is the fact that during the past year the share of new dwellings, built between 2008-2014, in the loans granted through „Prima Casă“ programme increased to 37%. Real estate consultants have noticed a visible bounce back of new apartment sales after the improvement of the access to real estate loans and price cuts applied by real estate developers in the past years. 
  
OCTAGON involved in the construction of residential projects

Residential projects have not had a major share in the portfolio of OCTAGON CONTRACTING & ENGINEERING, but the company was involved in the construction of several residential projects over the years, within which it performed civil and geotechnical works.

Residential complex Titeica
OCTAGON built the concrete structure of three residential buildings, diaphragm walls and bored piles D 600, for the residential complex Maresal Averescu 159.

Within the residential complex Tineretului Hills, located on Pajistei St. in Bucharest, OCTAGON executed diaphragm walls D 600 m, h = 13, top beam 60 X 100 m, bored piles and retaining walls.

Construction works at Brasov city belt to be resumed. OCTAGON has built bored piles for section I


Brasov City Belt

Construction works at Brasov city belt, a project that started in 2003 and which was temporarily stopped, will be resumed soon.  Brasov city belt is also one of the road infrastructure projects of OCTAGON CONTRACTING & ENGINEERING. In 2011 the company was geotechnical works subcontractor and built bored piles for section I.

Brasov City Belt- Bored pile cage launching
The National Highways and Roads Company (CNADNR) announced in a press release that the bid procedure for section I, streching between DN1 and DN11 and for section II, which connects DN 11 with DN 13, ended. Brasov city belt will have four sections, a total length of 24.3 km and two lanes on each traffic way. The road, built especially for the transport of merchandise and transit is open to traffic on two of the four sections.

So far only 56% of the works necessary for the completion of section one has been delivered. The section has a length of  7.2 km and starts from Dârstea area (from the current bypass, on which a bridge over Timisul Sec stream will be built), bypasses the landfill,  crosses the road to Tărlungeni, bypasses CET, crosses Timiş-Triaj area, and then reaches DN 11 (towards Sfântu Gheorghe) in the roundabout from Stabilus area.

Besides the two lane traffic road, the project also includes the construction of a passage, crossing DN 11 and the railway that leads to Târgu Secuiesc.

OCTAGON   performed the following works for section I of the city belt: bored piles D 1,080, cage ram in, bored pile concreting and bored pile injection.

Doubling section II which connects DN 11, the exit from Braşov to Hărman, to DN 13, the exit from Braşov to Târgu-Mureş is absolutely necessary in order to allow highway regime traffic. At the same time, an important issue faced by drivers crossing the city belt will be solved, the construction of a road passage over the city belt, at the intersection with the county road to, where many accidents have occurred.
