The largest elastic mounting building project in the company’s history

Vibration protection for a luxury residential complex in Moscow using Getzner’s materials

Moscow/Bürs. The 'Four Suns' luxury residential complex in Moscow has now been completed. It stands on a site above two underground railway lines. To ensure the buildings at the complex had effective protection against vibrations, those responsible placed an elastic mounting through out the entire building complex. For Getzner Werkstoffe – the Austrian specialists in vibration isolation – this meant implementing the largest elastic mounting building project in the company's history.

Between 2006 and 2010, the Office Stroj general construction company completed a luxury residential complex with a total area of 110,000 m2 in the heart of Moscow. The 'Four Suns' complex represents the largest elastic mounting building project in Getzner's history. The main challenge of this project was protecting the building complex from vibrations, as the 'Four Suns' stands directly above two underground railway lines. The Key to this major project's success was Getzner's ability to adapt the solution to the situation at hand. 'We can adapt both the thickness and parameters of the materials to suit the individual case. This allows us to devise very economical solutions,' points out Andreas Stofleth, the Project Manager at Getzner. The residential complex is situated on a common base plate upon which four 8-10 storey residential buildings are located. The foundations for the base plate and the residential buildings were constructed as a monolithic, reinforced-concrete, solid plate.

Elastic floor and wall supports for vibration isolation

In 2006, 'Ecocity', an ecological fund dedicated to developing the urban environment, conducted an investigation of the building site. As a means of insulating the building against vibration, those in charge recommended an elastic mounting using Getzner's polyurethane material Sylomer®. Offering protection from vibrations, elastic floor and wall supports made from Sylomer® were used under the foundation of the residential block and on the surfaces of the foundation walls. The elastic bearing beneath the baseplate consisted of a 37 mm thick layer of Sylomer®. 25 mm of Sylomer® was applied to the foundation walls.

Correlation between the predictions and the actual installation

Getzner was able to use Ecocity's predicted results to calculate the requirements for vibration isolation. Using the exact measurement results and the proposed technical solutions, Getzner was able to determine the ideal material for the elastic mounting at the luxury residential complex. The vibration experts produced the materials with these specific challenges in mind. 'The excellent correlation between the predictions and the actual installation is an indicator of the quality of the products and related services delivered,' points out Sergej Kurnavin PhD, highlighting Getzner's professional approach to both planning and implementation.

Professional building protection for excellent living conditions

Once the shell of the building had been erected, Ecocity undertook further test measurements. The results showed that using Sylomer® the construction team was able to achieve an effective level of protection against vibration. All areas subjected to investigation complied fully with the standards set by the Russian Federation. Professional building protection ensures excellent living conditions. Getzner Werkstoffe operates not only as a developer and producer of materials for vibration reduction, but is also particularly active as a construction advisor. In addition to performing material calculations, the specialists also took charge of project management at the site during the construction phase.
