Rubble Soling Rate Analysis
We already discussed about procedure of rubble soling
analysis, as well as discussed about checklist of rubble soling. Now in this
blog we will discuss about rate analysis of rubble soling work, with it’s types
and detailed calculation of work.
Soling is generally used at below PCC, soling is very useful
to transferring the load from structure to earth, soling is directly placed on
rock or hard surface, lot of times excavated rock surface is not in level, in
these location we need to place rubble soling to cover the undulations in
surface to work further.
Generally thickness of Rubble Soling is 230-300 mm, because
is it very easy to work as well as the size of stone is uneven so we need to do
rubble soling with skilled peoples to avoid the gaps, skilled peoples can place
the stone with suitable location and in level also, to fill the gaps they are
using small stone chips, and the minimum stone gaps can fill with murum. After doing
some compaction we can get uniform surface to work further. Before bidding any
tenders contractors are facing some questions are as follows.
what about its rate analysis?
Rubble soling is first work which is need to procure the new
material, therefore rate analysis is very important for rubble soling work.
How to decide the Rates of rubble soling?
This is the very big problem which are facing new
contractors.
How to calculate exact rate for rubble soling?
To calculate the exact rate of rubble soling work need to
know actual market rates and we are giving here actual rate analysis formats.
How to decide the constant?
Constants are decide are per work specification which is
clearly mentioned in tender copy.
What is labour rate?
To know the labour rate need to do little market survey.
What is Material Rate?
Material rate is depend on Quality of material, quantity of
work, supplier and site distance.
Now in this session we are going to calculate the rate
analysis with preparation of analysis format in excel.
Rate analysis of
Rubble Soling
Required Material & Labour
Material: 200-300 mm Stones , Murum, Construction Water
Labour: Skilled Labour which are expert in stone work.
There are two types of rubble soling which are commonly used
in construction industry. When you are calculating the constant of rubble soling,
there is big voids while material coming on site, If you ordered one brass
material from quarry you will get only 70-80% because of it’s voids, that means
if you want to work 100 Sq ft or 1 Brass then need to order 1.25 brass which is
almost 25% more than your requirement.

If you want to calculate the rate in another unit you can
convert this or make another rate analysis to get the exact rate of particular work.
Rate Conversion will be as follows
Rate for 01 Sq ft = Rs.
35.00
Rate for 01 Sqm = Rs. 377.00

Those rate may be varies as per location to location and
also it is depending on quantum of work also if work quantity is huge then rate
can be negotiable.
Before finalize the rate carefully check the current market
rate of labour and material. Which will very helpful to bid any tenders or give
any quotations.
If you have any query contact us, we will solve your issue.
