Bi–Directional testing of high capacity test pile at Krrish project
Geotech successfully conducted the first Bi-Directional testing of a
high capacity test pile on April 4 ,2013, at the prestigious Krrish
Luxury Lifestyles Project to evaluate the ultimate load carrying
capacity and other relevant parameters of the test pile, in association
with M/S Walkers Piling (Pvt) Limited who were responsible for the
construction of the pile and field installation.

The data gathered will be invaluable for the geotechnical and
structural engineers to optimize their foundation design for this
ambitious project, with towers reaching over 250 meters (90 storeys) to
the Colombo Sky line.
The test which incorporated four hydraulic jacks embedded in the
concrete pile, with an assortment of other sensors, stressed the pile to
nearly 5,000 tons and generated a wide spectrum of data on the load
carrying capacity of the soil strata and the basement rock.
As Colombo’s skyline changes with ever taller buildings standing on
piled foundations it becomes important that design engineers are
equipped with reliable, convenient and economical means to ensure the
efficacy of their designs, leading to cost effective foundations for the
development projects.
Thus the Bi-Directional Test will definitely have a very significant
impact on the construction industry.
Geotech is justifiably proud to have been able to periodically
pioneer the introduction of other such methods for evaluating the
condition of piles by state of the art electronic pile testing
techniques such as the Pile Integrity Test (PIT), Pile Dynamic Analysis
(PDA) Test and Cross Hole Analysis (CHA) Test. These techniques which
can be incorporated in the design stage itself, enable the optimization
of the designs supported by additional data, which cannot be gained from
the traditional static load tests.
Geotech Group, comprising of Geotech (Pvt) Ltd., Geotech Testing
Services (Pvt) Ltd. and Group Engineering Laboratories (Pvt) Ltd., are
proud to have been chosen with Walkers Piling (Pvt) Ltd to conduct this
test with support and the technical expertise of Strainstall Sdn Bhd of
Malaysia.
Geotech is thankful to the management of Krrish Transworks Colombo (Pvt)
Ltd. for the opportunity given to provide our services and to introduce
this valuable test to support the industry and infrastructure
development in Sri Lanka. A technical discussion has been arranged to
disseminate the details of the test method to geotechnical and
structural engineers as well as piling contractors and project
developers. |
