Get detailed
information on how to choose the pile foundations on the basis of cost vs.
other foundations for construction projects and factors which impact the cost
of pile foundation.
Sometimes, it
becomes difficult for structural designer to take stable decision to select
types of foundations like pile foundation or ordinary strip or mat foundation
to be used for the structure.
The problem becomes acute while going to choose among pile
foundation and traditional mat or strip foundation developed in a deeper level
to fit a soil layer having desirable bearing strength.
There
should be an indicator for all construction conditions under which the use of
pile foundation is considered as inexpensive with reference to traditional
strip and mat foundations.
This
article will focus on the variations through which the decision for choosing of
pile foundation over other foundation types can be taken without difficulty.
This condition line is formed on the reasonably detailed cost appraisal of the
foundation. The foundation cost is impacted by the following factors :-
Factors
impacting the cost of Pile Foundation
Evidently, final
decision for employing the type of foundation, cannot be taken on the basis of
the calculation of excavation volume and concrete quantity of deep mat or strip
foundation with regard to cost of piles that support the same load.
A cap is needed for Pile foundation. The density of the cap should
be approx 45cm for two piles and 60cm to 120cm for two pair of piles. Plan
dimensions of piling cap should be up to 2100mm2 for pile having diameter of
550mm.
With
tie beams provided over one direction, the Pile caps are joined together using
tie beams in more than one direction.
It is found that, the excavation cost of pile cap along with
capping beams and tie beams is two times the cost of machine excavation in
moderately large column bases. With the advancement of construction, the
perfect structural design as well as stringent supervision is required for pile
foundation.
