team of 25 engineers. Time saving through timber construction with binderholz crosslaminated timber BBS can be very substantial for the construction of large-volume buildings. The high degree of prefabrication shortens construction times considerably. Load-bearing wall elements just have to be shifted and connected to one another. Drying times for brickwork or floor pavement are dispensed with. Owing to their comparatively low weight, these prefabricated timber elements can be dimensioned on a very large scale. Since installations are laid in the hollow space between the plaster board system and the timber element, there is no need for subsequent chiselling and plastering.

Complex roof structure

Bilderholz Bausysteme designs and manufactures cross laminated timber BBS panels for public & municipal buildings, commercial buildings, multi-storey housing projects, family homes and special projects.

The awe-inspiring Centre Pompidou Metz is a branch of Pompidou arts centre of Paris, and features exhibitions from the large collection of the French National Museum of Modern Art, the largest European collection of 20th and 21st century arts. Since its inauguration in 2010, the museum has become one of the most visited cultural venues in France outside Paris. The building is remarkable for its timber roof structure, constructed by Holzbau Amann and manufactured by Binderholz Bausysteme. The roof structure, one of the largest and

most complex built to date, was inspired by a Chinese hat found in Paris by the building’s Japanese architect Shigeru Ban.

A 7-storey building in Vienna and an 8-storey building in a German town were up until 2013 Binderholz Bausysteme’s tallest timber-built housing projects. For 2014 a 10-storey building project is scheduled to be carried out in London.

In Italy, an earthquake hit region needed affordable housing, able to withstand future earthquakes, quickly. The Binderholz Bausysteme engineers and the main Italian binderholz clients designed a housing project comprising 373 homes, with high elastic absorption properties and a high density of mechanical joints, thus increasing the building’s ductility, and better arming it against seismic forces. The project was finished in less than six months from the date of its inception.

Looking to the future, Helmut Spiehs says, “Since 2006 we have seen an annual growth of 30 per cent, and as international surveys show that timber construction has a great future, we expect Binderholz Bausysteme to further expand its sales beyond the European market.” n

CEMENTING SUCCESS

OYAK Cement Group is the market leader in the Turkish cement industry and an integral part of OYAK, a pension fund and one of the biggest conglomerates in Turkey. Semra Çelebi met with Celal Çağlar, Cement Group Chairman.

OYAK’s primary source of funding is a 10 per cent deduction made against the salary of all members of the Turkish armed forces, including related civil servants, and the company is thus in charge of the biggest pension fund in Turkey. The firm invests this income in the money markets or in company shareholdings and owns considerable holdings in Turkish industry, particularly in cement, iron and steel production. It is the main shareholder of the Erdemir iron and steel factory, OYAK Renault & MAIS; automotive production and marketing companies, joint ventures with Renault that produce 360,000 passenger cars per year, and is involved in an electricity production venture with the Steag Group that supplies five percent of the energy used in Turkey.

Cement holdings

OYAK started investing in cement in 1963 through Adana Cimento and became a founding shareholder in Bolu, Mardin and Unye Cimento. Through the years OYAK has divested two cement companies (Elazig Cimento in 2006 and Nigde Cimento in 2007) and acquired Aslan Cimento, the first cement factory in the country in 2009. Currently the group has an annual production capacity of 8.5 million tonnes of clinker and 17.5 million tonnes of cement, the largest in Turkey.

Adana Cimento is one of the oldest and biggest cement factories in Turkey, situated in the Mediterranean area. Mardin Cimento is the main cement provider in Southeast Anatolia and in Middle Eastern countries. Bolu Cimento caters for the Marmara and Central Anatolia regions and produces slag cement, G type oil-well cement and other special products. Unye Cimento is the biggest producer in the Black Sea region and Aslan Cimento operates a large factory close to Istanbul.

The Group has formed several new firms and acquired companies in order to facilitate vertical integration. These include OYKA, a paper and packaging company that operates Turkey’s only integrated paper factory and OYAK Beton, a large ready-mix concrete producers that serves nearly all the large building projects in the country.

Supporting Turkey’s flagship construction projects

The group’s most important product is standard grey cement, although it also produces white cement, a niche product requiring non-abundant raw materials and special production processes. Another unusual product is its sulphate resistant slag cement, which uses by-products from steel factories owned by the OYAK. Bolu Cimento produces oil-well cement and works with Beton to make special cement used in large-scale projects, such as the new Marmaray tunnel which was built under the Bosphorous. OYAK Beton has also provided materials for many other important infrastructure projects and the building of new mosques.

Although the supply of cement has exceeded demand for the last few years, OYAK has nevertheless invested in a new kiln in its Ankara grinding facility. The project
