Let us assume that you have been given the BOQ [ Bill of Quantities ]with several items which you need to execute at the site. Before execution , you need to submit the rates for the individual items .This is known as Complete Item rate.

In context of a Construction tender , a completed item rate is the rate at which you are going to offer to complete the work.

The completed item rate , therefore , has the following components :

Material cost including the Base rate , Loading , unloading charges, Transportation , Storage etc. You shall also have to add the probable wastage that might take place during handling, storage , local conveyance and during the execution.

Labour cost .This shall depend on the skills . degree of specialization needed to execute the work etc. In specific items , the tender might refer to proprietary items . [ What is a Proprietary item ? ] . In such case , it shall be required to get the quote from the qualified Applicators. Usually , there shall be approved agencies who are qualified by the Manufacturer for application of their products at site.

To the subheads 1 & 2 , you shall have to add the following :

Supervision

Administration

Tools and Plants

Overheads

Contractor’s profit

TDS

Such addition of 1, 2 & 3 shall give you what is known as the Complete item rate for that item.

In this context , now let us see one real life example .

Suppose you have been given a BOQ as follows and you are asked to do the rate analysis for the individual items .

Let us sample the first item for discussion here :

Now . what is the next step ?

In this case , the BOQ has specified the India Gypsum as the Approved Product / manufacturer.Therefore , it is necessary that you visit the web site as following link :

Henceforth , you need to take the following steps :

Visit the Web page

Contact if there are local dealers/ stockists of the specified product.

Obtain a price list

Find out if Approved Applicators are available

Obtain a quote from the Applicators

Arrive at the Complete item rate as explained in the first paragraph of this post.

Repeat identical steps for each of the item in the BOQ.

It is suggested that the actual calculations for the rate Analysis are carried out in the MS Excel . This shall help you when doing some corrections in the tabulation or when you have do identical calculations for the next item.

In case you would like to learn the science of doing the Rate analysis in a methodical way , do contact me using this form here :

When I was standing in a car park , waiting for someone to complete the shopping ,

I got a Whatsapp message from one of my students , asking me for the Rubble masonry rates. He said he wanted to submit the quotation on the same day. There was no use of just giving him a rate which I remember because it has to match with the material and labour rates and profit margin expected by this person.

So , I had to make a rate analysis for the Rubble masonry .

I asked him to message me the basic rates which he promptly did.

I next 15 minutes , I completed the rate analysis and send back the entire analysis to him .

Thought I shall also share the same calculations with you for your quick reference.

Part A : The data :

Cement: 300/bag

Aggregate: 2400/brass

Rubble : 1500/brass

Labour :2000/brass

Sand 5500/ brass

You already know that : I brass = 100 Cft

Desired Profit 25%

Specifications :

Rubble masonry Width 18″

for wall compound ht 3′ from ground level

in cement mortar in ratio : ( 1:6 )

Material for 1 cum:

Cement : 300*(0.45*1.52*28.8)/7= Rs.844

Sand: 5500*0.3529*6*(0.45*1.52)/7= Rs.1138

Rubble: 2400*0.3529*1.25 = Rs.1058

Labour : 2000*0.3529= Rs.706

Total: Rs.3756

Profit:Add@ 25%: Rs.937

Total: Rs.4693 Rs/cum.

Or Rs.133 per Cft.

PCC 1:4:8

Material for 1 cum:

Cement : 300*(1.52*28.8)/13 = Rs.1010

Sand: 5500*0.3529*4*1.52/13 =Rs.908

Aggregate: 2400*0.3529*8*1.52/13 = Rs.792

Sub total: Rs. 2710

For Labour Add 40% Rs.1084

Total : Rs. 3794

Profits Add25% Rs.949

Total : Rs. 4743 per Cum

Rs. 134 per Cft.

Note :

1.You shall observe that the rate for Rubble masonry in cement mortar in CM 1 :6 and the rate for plain cement concrete in proportion 1:4:8 are almost equal

2. The material wastage is a point on which I need to elaborate.

As such when we consider the factor 1.52 in the material calculations by dry mix method, we are already considering 2 % material wastage . In case you want a higher allowance for wastage , you may take the factor as 1.57 so that material wastage is 7%.
