COMPANY HISTORYThe history of OCTAGON CONTRACTING & ENGINEERING began 10 years ago. In 2005, a small but enthusiastic team, bringing together people with a broad experience in construction, laid the foundation of the company. OCTAGON opened in Bucharest during a period of fervent development of the construction market. The company worked from the beginning on many projects from all the construction sectors.
OCTAGON TODAYAfter 12 years of accomplishments, challenges and hard work, OCTAGON is now one of Romania’s top contractors, recognized for the quality of its works and its ability to deliver large, complex projects. In time, the team has grown to 116 employees, the number of built sqm has significantly increased and the turnover in 2016 exceeds 30 mil. euro.
2007 - 2009OCTAGON built the foundation of the tallest building in Bucharest: Sky Tower (137 m) which included the deepest excavation in top-down system in Romania (2009). The residential complex Maresal Averescu 159 and the office building Olympia Tower, both located in Bucharest, are two other projects where OCTAGON performed infrastructure, structure and consolidation works between 2006 and 2009.
2005 - 2007During the first two years, OCTAGON developed its first partnerships with clients that are still part of the company’s portfolio, and we focused on strengthening the company’s capabilities as a geotechnical construction contractor. This was a time when market integration, strategy planning and research into business opportunities were extremely important.
2011 - 2012During these two years OCTAGON took a major step in its development strategy. The company expanded to a new continent by opening a branch in Baghdad (Iraq), and is now working on projects in both Baghdad and Basra. In 2011 OCTAGON acquired the construction material supply facilities Comat Electro, located in Bucharest.
2015 - 2016 During this time OCTAGON continued works on the most complex project in the company’s portfolio Hermes Business Campus, executing the foundation of building A3, as general contractor. The company also performed geotechnical works on the projects Timpuri Noi Office Building and the expansion of City Park Mall Constanta.
2013 - 2014OCTAGON successfully delivered two major projects in its portfolio: Green Court Bucharest- buildings A and B, and Hermes Business Campus- building B.
2014 - 2015 In 2014 OCTAGON f inished the construction works on one of the most important infrastructure projects in Romania: the Underground Passage in Piata Presei Libere in Bucharest. The company is currently performing geotechnical and civil construction works on buildings C and A of Hermes Business Campus office complex and on the residential complex One Herastrau Park in Bucharest.
2016 - 2017It was a year focused around the construction of building A3 of Hermes Business Campus complex. Orhideea Towers and Business Garden Bucharest off ice buildings, both located in Bucharest, for which OCTAGON performed geotechnical works, are among the company’s accomplishments during this period.
2010 - 2011OCTAGON worked on one of the largest private power generation projects in Romania: Combined Cycle Power Plant 867 MW OMV- Petrom Brazi. Metka & GE consortium, the project developer, began the development in 2009.
2009 - 2010After three years of experience in Romania, OCTAGON also approached the international market and contracted projects in Turkey, Greece and Bulgaria. A residential building in Larisa (Greece) and Samsun Power Plant in Turkey are some of the company’s projects abroad.
2012 - 2013 OCTAGON undertook its first project as a general contractor: the construction of building B of the office complex Hermes Business Campus. The company had previously built the foundation of the same office building in top- down system.

Works on building B1, the first building erected within the complex, began in December 2010, when OCTAGON was appointed geotechnical construction works contractor. The company later continued working on the project by building the superstructure of the building. Three hundred people were involved in the construction works and 31.000 cubic meters of concrete and 3.600 tones of iron were used. The building was BREEAM certified with excellent grade for architecture and construction works.
COMBINED CYCLE POWER PLANT 867 MW OMV- PETROM
Only three years after the set- up, OCTAGON became contractor on one of the largest greenfield power projects in Romania: Combined Cycle Power Plant 860 MW OMV- Petrom. In 2008 OMV- Petrom contracted the consortium General Electric- Metka to build the power plant, located in Brazi (Prahova county), near Ploiești city. The power plant has the following technical configuration: two gas turbines with capacities of 290MW each, a steam turbine with a capacity of 310 MW, 2 steam generators with heat recovery and 3 generators. The power plant is connected to the national gas and power grid through a 30 km gas pipe and newly built electricity lines of 2 x 3 km and has a 9% production share in Romania’s consumption. OCTAGON performed geotechnical, structural, architecture, electricity, sanitary and air conditioning works on the project. The geotechnical works consisted in the execution of bored piles D1,200, h= 24 m. The company built reinforced concrete foundations for 42 buildings, part of the power plant. The access roads and platforms were also built by OCTAGON. In 2010 the construction company delivered the works on the power plant, which started commercial operations in August 2012.
We recommend OCTAGON for the quality of the technical data and for the efforts made to prepare the reports, for the ability to comply with the specified quality standards, for the technical performances, for the efficiency in tackling contractual issues without detailed guidance of the client and for the efficiency of the quality control programme, as well as for complying with the quality contractual demands.”
METKA
THOMAS MASARYKPATRIMONY VILLA
Historical and heritage buildings are restored and preserved for future generations, for several reasons. The main reason is the owner’s wish to live in a space filled with historical significance. This is also the case of the heritage villa located on 34 Thomas Masaryk Street, in Bucharest, restored and consolidated by OCTAGON.
The restoration process includes works through which a building is adjusted to contemporary use, preserving, at the same time, its historical value. This is a complex process, that required increased attention to details and includes identifying, retaining, preserving and protecting the materials and features from the time when the building was erected. Also, deteriorated materials or features are replaced through restoration, with the purpose to give the best possible shape to the building.OCTAGON performed general restoration, consolidation and revitalization works within this project: new partitions, wooden roof restoration,parquet coatings, central heating installation, water and sewage installation, electrical and conditioning installation.
2008 was the year when many construction companies started to experience the negative effects of the real estate market, but OCTAGON kept working on projects, important in terms of size and value. One of these projects is the residential complex Alia Apartments. Located in Bucharest city center, on 159 Maresal Averescu Blvd., in an area that gives easy access to parks, museums and restaurants, the complex includes three buildings of various heights 2B+ GF+ 20F, 2B + GF+ 8F, 2B + GF + 6F. OCTAGON was a geotechnical construction contractor and performed: infrastructure and structure consolidation works, doubling of the foundation beams, interior masonry works, additional interior piles, renovation of the wooden roof and perimeter closing with reinforced concrete fence.
ALIA APARTMENTS
OCTAGON performed geotechnical and civil works for two buildings of the office complex Green Court Bucharest, located in the north of the capital, on Barbu Vacarescu Boulevard. Developed by Skanska Development Romania, the complex includes three buildings with a total area of 52,000 sqm and extended office spaces. Green Court Bucharest is a complex with many “green” elements. The glass facades with low thermal transfer, solar panels placed on the roof, natural light in over 75% of the building, electrical plug- ins for cars and parking spaces for bikes are only some of the “green” solutions implemented by the developer.
BUILDING ABuilding A has a total leasable area of 19,500 sqm, 12 floors and 3 basements and was delivered in 2014.

OLYMPIA TOWER
CULTURE AND OFFICE CENTER THE ARK
An old, shattered building, spectacular through architecture, that reminded of the end of the 19th century Bucharest: this is how the culture and office center Vama Antrepozite looked like in 2005, before renovation. Located at the junction of Calea Rahova and Uranus Street, Vama Bucuresti Antrepozite was built in 1894 and is a historical monument class B. After three large fire outbrakes, which occurred between the beginning and the end of the 20th century, the office complex, jewelery of the industrial architecture looked old and abandoned. Between 2005 and 2007, the most famous building of the complex- The Stock Exchange” was renovated by OCTAGON. The company worked on both the interior and the exterior of the building. OCTAGON doubled the foundation beams and consolidated the concrete structure. Partitions and supplementary interior columns were built inside the complex. The brick faÇade was kept, the wooden roof was replaced and the back of the building was completed in modern style. The building is now called THE ARK and was converted into a space used for displaying cultural projects, hosting an office area, a public exhibition space and a market for creative industries.
The project raised many challenges and OCTAGON faced them with creativity and determination. This approach lead to the successful delivery of the building. Our collaboration with OCTAGON was a pleasant working experience, as the company was highly committed to the project. The site works were managed in a professional manner and the quality of work and safety were also high. As a result, it is a pleasure to recommend OCTAGON as a top construction contractor.”

TIMPURI NOI OFFICE BUILDING
CATHEDRAL PLAZA
The top-down construction method is one of the best building solutions for buildings with multiple basements, that need deep excavations. The construction method was adopted at the beginning of the 60s and is currently used for the construction of buildings located in crowded urban areas. The main advantage of this construction method is the fact that the infrastructure and the superstructure of the building can be built simultaneously and the execution time is significantly lower. The excavation is supported with the help of the basement ceilings instead of temporary support systems, which is cost efficient. The office buildings can be successfully built using this method. In 2012 OCTAGON performed special excavation works in top-down system for a large number of office buildings, among which Cathedral Plaza as well. OCTAGON built final diaphragm walls D800 mm, bored piles D1.500 mm and D1.800 mm, metal profile mounting in piles and monitoring of dewatering systems.Cathedral Plaza is located in Bucharest city center, at the junction of General Berthelot and Luterana Street, has 19 floors, a 75m height and a GLA of 23.000 sqm.
UTI Business Center is a class A office building, with a GLA of 14,000 sqm, stretching over 11 floors. The building is located in Bucharest city center, on 31 Vasile Lascăr Street. In 2007 OCTAGON took over the geotechnical construction works, that consisted in the execution of D600 mm diaphram walls, bored piles D880, crown beam 60 x 150 cm, general excavation 14,200 cubic meters and support system with metal frames.
One of the projects executed by OCTAGON at the beginning of the company’s activity, in 2006, is BOS off ice building, located near Piata Victoria, on 63-69 Dr. Iacob Felix Street, in Bucharest. The building provides easy access to ground public transport connections, but also to the metro stations Piata Victoriei and Gara de Nord. Within this project OCTAGON built diaphragm walls D800, bored piles D880, crown beam, dewatering systems and optimization of geotechnical works project.

ROAD INFRASTRUCTURE AND RAILWAY WORKS
Romanian road infrastructure has undergone an extensive development process in the past years. This process has included the construction and modernization of roads, highways and railways. Public investments allocated for the development of these project varied from one year to another, but the final purpose has always been the same: adjusting to a transport system able to meet the needs and requirements of the European Union membership terms. OCTAGON was intensively involved in this development process, building parts of major national road infrastructure and railway projects.

Crossing area between the center and the north of the city, Piata Presei Libere is one of the most crowded points on the map of Bucharest. The need to improve the traffic conditions, reduce the level of pollution produced by vehicles and the number of accidents caused by traffic jams, were reasons strong enough for Bucharest City Hall to initiate in 2014 the development of an underground passage. The passage is 700 m long and has two exits. One of the exits was built towards Kiseleff Road. The exit towards Marasti Boulevard allows cars to cross the area from any direction and connects the public ground transport, tramway and bus lines, with the station of the future Metro Line 6. The diaphragm walls, some of the most important elements of the passage, that ensure the stability and resilience of the construction, were built by OCTAGON.
PIATA PRESEI LIBERE UNDERGROUND PASSAGE
Road infrastructure has become in the past years one of the main construction sectors approached by OCTAGON. The large number of projects in which the company was involved stand as a proof. One of these projects is section II of Bucharest- Nadlac Motorway (A1), part of the Pan European Transport Corridor IV. At the end of the works the motorway will have 576 km and will link Bucharest with Pitesti, Sibiu, Sebes, Deva, Lugoj, Timisoara, Arad and Nadlac, ensuring the connection with M43 motorway from Hungary, towards Seghedin. Section II Orastie-Sibiu is 82.1 km long and includes four lots. Lots 1,2 and 4 were open to traffic in December 2013, while lot 3 became functional in November 2014. OCTAGON performed geotechnical works for lots 2, 3 and 4 of the motorway. The works consisted in the execution of bored piles D1,200 under bentonite mud protection, pile base injections and static nondestructive test.
OCTAGON worked efficiently and made all the necessary efforts to find and implement the best construction solutions on the project. The company also had the financial capability, equipment and specialists which enabled it to deliver the project in accordance with all the terms in the contract.”

CITY TOWER SOFIA
Built in a strategic and prestigious location of Sofia, City Tower offers large companies the opportunity to relocate their operations at the “heart” of the city, on Macedonia Street, at the junction of Hristo Botev Boulevard and Alabin Street and benefit thus from all the advantages and facilities provided by the city center. The location is easily accessible from all the directions, the complex is surrounded by a versatile area with bars and restaurants, 5 star hotels and government buildings. City Tower, an A class business and retail complex, includes several “green” elements and was BREEAM certified. The complex overlooks the entire city and the Vitosha Mountain. The office area covers 31,000 sqm stretching over a 20- storey tower and an 8- storey building, connected through an architecture configuration which provides space flexibility. Each floor has an unique and practical plan, offering thus a wide variety of possibilities to divide the space, depending on tenants’ needs. The two buildings also have six underground parking levels counting 369 parking spaces. The retail area which covers 5,300sqm spreads over two floors, around a 90 sqm central atrium and includes stores, coffee shops and a cinema area with access from either Alabin Street or from Macedonia Street. OCTAGON built the foundation of the office and retail complex in top- down system. This construction technique allowed OCTAGON to build simultaneously the basements and several floors of the building superstructure. The works included diaphragm walls D800, h= 28 m, 5,900 sqm; 23 bored piles D1,000 mm, h= 40 m; 13 bored piles D1,200 mm, h= 40 m; 20 bored piles D1,500 mm, h= 40 m and a dewatering system. OCTAGON delivered the works in March 2008 and the building was inaugurated at the beginning of 2012.
OCTAGON had a professional and ethical conduct during the contract development. The initial graphics were met and the works were delivered within the agreed deadlines. The execution costs were fair and the communication with our partner in this project was clear and open all through the project. OCTAGON remained involved in supervising the works from beginning to delivery.”
TERNA AD
The international experience, acquired by OCTAGON over the year, while building projects in countries such as Bulgaria, Greece and Turkey recommended the company for completion of geotechnical works within an industrial project that combines high efficiency and flexibility, necessary to participate on the electric power distribution market in Turkey. In 2010, OCTAGON became geotechnical construction contractor for a natural gas power plant with a 870MW capacity, built in Samsun (Turkey).

For the opening of its first office abroad, OCTAGON chose a country with high development potential on the construction market, a potential generated by the shortage of dwellings and the need to make massive investments in road infrastructure. Under full reconstruction process, Iraq is also a destination with many challenges, especially related to safety. In 2011 OCTAGON opened Baghdad branch and after only three months started working on three projects. OCTAGON used the experience gained while performing construction works on the Combined Cycle Power Plant 860 MW OMV-Petrom (Brazi) for the execution of geotechnical works on the Electric Power Plant 1250 MW Shatt Al-Basra, located in Basra. OCTAGON built bored piles D1,000 on this industrial project.
-SHATT AL - BASRA POWER PLANT
In 2017 OCTAGON renewed its long term collaboration with Metka – General Electric (GE), the consortium that subcontracted the company to perform geotechnical works on the project Combined Cycle Power Plant 192MW, built in Takoradi (Ghana). Within this project OCTAGON performed bored piles and wick drains. The power station will use natural gas and light oil as fuel and will also use an advanced version of the gas turbine 9E, developed by General Electric.
TAKORADI - GHANACOMBINED CYCLE POWER PLANT
AL ZAWRAA STADIUM
In 2011 OCTAGON approached a new market, with high development potential, following the favorable political and economic environment. The company opened a branch in Baghdad (Iraq) and decided to get involved in the reconstruction of this country, that is still severely affected by the long term war. Several large scale infrastructure and real estate projects have been launched by both the state and private investors, and a combination of several economic, political and social factors make Iraq a favorable destination for business and for investments. Iraq, that owns the third largest oil reserves in the world, is making efforts to capitalize these resources and direct the investments towards the reconstruction process. OCTAGON started to get involved in the execution of construction projects soon after opening the branch in Baghdad. One of these projects is Al Zawraa Stadium in Baghdad, where OCTAGON executed bored piles D1.000 mm, cage installation and concreting works.
