Innovation infrastructure.

every year, some US$ 2.5 billion are invested in infrastructure worldwide.

This is not enough by any means, as a recent study by the McKinsey Global Institute

(McKinsey&Company) dated June 2016 demonstrates. As far as can be seen today, an investment of

US$ 3.3 billion annually until 2030 would be necessary to keep pace with population growth, urbanisation and demographic

change. In order to bridge the gap, a variety of approaches will

be necessary from both politics and industry. The construction sector is here called upon. One lever would be an increase in productivity in the construction of infrastructure projects because a reduction in construction times also reduces the required investment.

INNOVATION FOR AN IMPROVED INFRASTRUCTURE It is evident that an enormous amount of potential is still dormant within the construction sector. According to a study, some 57% of the operations in construction are due to activities which do not create added value -- for example, inefficiencies, errors or lack of communication. Studying the development of productivity in the building industry, focusing on important industrial countries like Germany, the United Kingdom and the United States, it is clear that during the past twenty years this construction potential has stagnated or even declined, as the current study by the McKinsey Global Institute proves. As a supplier to the construction industry, the Doka Group makes an important contribution to increased productivity within the sector and hence to infrastructure projects. International formwork experts from Austria aim to make the entire construction process even more efficient in the future -- from planning to building to maintenance and ultimately even the disposal of property. The formwork experts have already taken a number of crucial steps in this direction. Doka deals with innovative technologies, building materials and methods and is also expanding its expertise, most recently with the takeover of the Dutch technology company B|A|S. The company is thus actively promoting change in the building sector -- focusing on increased efficiency and profitability.

Following doka projects lead by example:

Muskrat Falls -- A superlative hy- draulic power station project (CAN) Concrete crack prevention and consequently leakage is a prime criterion for the construction of hydropower plants. This also holds true for the 824 MW hydropower plant Muskrat Falls in Canada, which will supply electricity to

the provinces of Labrador and Newfoundland. Because extreme weather conditions were a major challenge for this project, concreting on this site had to continue even when temperatures plummeted to -40 Celsius in winter and rose to +30 Celsius in summer. With hundreds

of measurements, Concremote -- the new concrete sensor technology by Doka -- ensured reliable on-site temperature monitoring and hence secured quality of these mass concrete structures. Temperature development measurements are fundamental

for monitoring thermal stresses in concrete that develop as a result of temperature variances. This data helps to put into place avoidance actions mitigating development of thermal cracks and the potential for future structural damage.

Three World Trade Center -- New York acquired 260,000 m2 more infrastructure (USA) Tower 3, with 80 storeys, was built at the heart of former Ground Zero. Doka made an important contribution to keeping formwork times as short as possible with the Doka Super Climber SCP, the rapid self-climbing formwork system for the North American market. Doka engineers contributed much to the planning phase so the optimum formwork solution could be defined early in

the project. In regards to safety, Doka supplied top quality safety systems incorporated into solutions which surpassed the requirements of New York City's building code and those of the Port Authority of New York

and New Jersey. This skyscraper was designed by architect Richard Rogers and offers over 260,000 m2 office and shop space. Doka provided a formwork solution Tower 2 and 4.

Doha Metro -- Public transport infrastructure for Qatar (QAT) This project is on track for a 2020 launch where this state-of-the art integrated metro line will be one of the most advanced rail transit systems in the world. The Doha Metro includes in the first phase over 111

km of underground tunnel sections and 37 stations. The Red Line, also known as the Coastal Line, forms the key line in Qatar's infrastructure system. In order to expedite progress on site, Doka Qatar provided pre- assembly services for Large-area formwork Top 50 base slabs, lining walls, lift walls and staircase walls, as well as pre-assembly of the Load- bearing tower Staxo 100. Fabrizio Fara, Assistant Construction Manager ISG JV pointed out how Doka added

to efficiency on site: "The Doka system is known for its dependable quality, however in addition to this, the industry knowhow amongst both the sales and engineering teams has offered a big advantage in terms of job safety and efficiency."

Midfield Terminal Complex -- Extension Of Abu Dhabi International Airport (ARE) The Midfield Terminal Complex at Abu Dhabi International Airport is

currently one of the most impressive construction projects in the Emirate and at the same time the core element in the growth strategy "Abu Dhabi Economic Vision 2030". Doka is supporting the extension of the air traffic hub with high-performance formwork systems. This solution enables a shifting of formwork from one 20 m tunnel segment to another within three days only.

ABOUT DOKA:
