Spectacular Architecture with DYWIDAG Post-Tensioning Systems:
The Clearpoint Residencies Tower in Sri Lanka
The current construction boom in Sri Lanka has led to wide spread usage
of post-tensioning systems in high rise buildings because these systems
make it possible to build extraordinary and seismically resistant designs
with long cantilever spans.
DYWIDAG Post-Tensioning Systems were
used in the Clearpoint Tower, which will
be the tallest vertical garden in Asia after
its completion. The use of post-tensioning
systems made it possible to build cantilever
swimming pools and balconies in the 46 level
high building that is being constructed in the
Colombo district of Rajagiriya.
The tower includes 5m cantilever balconies
surrounding the entire building that required
a high load-bearing capacity in order to
accommodate the loads of the planned
plantings. The tower also features 10
swimming pools extending in 5.1m cantilevers.
Utracon supplied and installed 74t of
DYWIDAG Strand Post-Tensioning Tendons
in the cantilever beams, flat slabs and walls.
The stressed beams enabled the construction
of flat girders so that each level has the same
floor to floor clear height.
In the cantilever swimming pool slabs,
Utracon installed and stressed 30
Type 4-0.6" DYWIDAG Strand Tendons
with FA Flat Anchorages. In the cantilever
balconies, a total of 328 Type 5-0.6"
DYWIDAG Strand Tendons including
FA Flat Anchorages and 716 Type 7-0.6"
DYWIDAG Strand Tendons including
MA Multiplane Anchorages were installed
and stressed.
The General Contractor was very satisfied
both with the DYWIDAG Post-Tensioning
Systems that made it possible to realize the
extraordinary architecture of the Clearpoint
Tower and with the competent technical
support provided by DSI’s licensee Utracon.
