Description of the project

The Getzner Solution“Four Suns” luxury residential
complex in Moscow

Elastic floor and wall mounting asprotection against vibration

Bn 2006, “Ecocity”, the ecologicalfund for developing the urban environment, conducted an investigation of the building site. As a meansof insulating the building against
vibration, those in charge recommended an elastic mounting using
Getzner Sylomer®. At the time, the“Four Suns” luxury residential
complex was the largest building
mounting project since Getzner
Werkstoffe's existence.

etween 2006 and 2010, the Ofice Stroy general construction
company completed a luxury residential complex with a total area of
110,000 m2 in the heart of Moscow.
The main challenge of this project
was protecting the building complex
from vibrations, owing to the locationof the “Four Suns” which is directly
above two underground rail lines.
The residential complex is situatedon a common baseplate upon whichfour 8-10 storey buildings are located.
Both the foundations for the baseplate and the residential buildings
were constructed from monolithic
reinforced solid-concrete plate. The
trafic passing along the Kalininskaya
and Kaluzhsko-Rizhskaya underground rail lines that run directly beneath the planned buildings, causes
vibrations which can still be detectedon the surface.

I

Elastic loor and wall mounting ofSylomer® as protection against vibration was applied beneath thefoundations of the residential blockand to the surfaces of the foundation
walls. The elasticated layer beneaththe baseplate comprised of 37 mm(thickness) of Sylomer®. A thicknessof 25 mm of Sylomer® was applied
to the foundation walls.

Individual vibration levels
Ecocity predicted the anticipatedvibration levels using the “FiniteElement Method”. Here the following
approach was used:
1 Measurement of the vibrationlevels in the foundation pit
2 Numeric calculation of the wave
propagation from the source tothe receiver, e.g. from the tunnel
to the surface and then to theplanned building
3 Combination of the forecast
calculations
4 Testing in the completed building
Getzner was able to use the forecast
results to calculate the requirementsof the vibration-insulation materials,
which allowed the experts to determine the ideal material for the elastic
mounting of the residential complex.
“This special forecast method wasdeveloped by Sergey Kurnavin of Ecocity over a period of 20 years. It is
unique in the world”, states Andreas
Stoleth, Project Manager at Getzner,
explaining the signiicance of themethod.

Feedback
DesignUsing concrete measurement results
and the proposed technical solutions,Getzner was able to determine themost suitable vibration insulation forthe luxury residential complex. The
vibration experts produced a material especially to combat thesechallenges. “We can adapt both thethickness and parameters of thematerials to the individual case, whichallows us to devise very economicalsolutions”, explains Stoleth, highlighting Getzner's unique sellingproposition. The company operates
not only as a developer and producerof materials for vibration reduction,
but also as a construction advisor.
Beside the material calculations, thespecialists also took charge of project
management during the construction
phase at site.

Effective protection against
vibration
After constructing the building shell,
Ecocity 2010 once again performeda series of tests. By using Sylomer®,the construction specialists reached
an effective level of protection
against vibration: All areas subjected
to investigation complied fully withthe standards set by the RussianFederation. The professional building
protection has created an excellent
quality of living.

“The full range of documentationfrom Getzner allows precisecalculations of complex vibration
issues. The excellent correlation
between the prediction and theactual installation is also an indicatorof the quality of the delivered
product and the related services”.
Sergey Kurnavin, PHD
