मराठी ब्लॉग बंद करावा का ?

मराठी ब्लॉग चे काय करावे ?
आपले विचार आवश्यक आहेत .

Construction in Marathi

मित्र हो ,

नमस्कार .

आपल्या बांधकाम क्षेत्रात काम करणाऱ्या लोकांसाठी आपण हा ब्लॉग सुरु केला . बरेच जणांना इंग्लीश भाषेची अडचण होते.

आजची हि परिस्थिती आहे :

अश्या सर्व व्यक्तींसाठी काम करायची माझी इच्छा होती [आणि अजूनही आहे.]

बरेच काही विचार मनात आहेत परंतु अनेक बाबीं  मुळे नेवीन काही लेख इथे लिहावयाला जमले नाही.

जसे हवे तसे ह्या वर अजून पर्यंत काही काम माझ्या हातून घडले नाही ह्याची खंत मला आहे.

ह्या आपल्या मराठी ब्लॉग चे काय करावे ?

बंद करावा कि सुरु ठेवावा ?

आता माझ्या समोर असे दोनच पर्याय आहेत.

  1. हा ब्लॉग बंद करून टाकावा व फक्त इंग्लीश ब्लॉग वरच काम करावे का ? कारण बंद करणे अतिशय सोपे आहे.                            एका मिनिटात बंद कर्ता येईल. परंतु ज्या २८ जणांनी  ह्या ब्लॉग ला follow केलेले आहे त्यांच्या वर अन्याय होईल असे मला वाटते.
  2. हा मराठी…

Footings : Levelling Course & Water Logging :

Dear Friends ,

Let us solve the query of one of the readers today.

This is the query :

1

In fact , there are two queries here :

  1. When do we use Plain Concrete in a footing ?
  2. Ground Water seepage during excavation ?

Let us solve these queries one by one.

First query is about the Plain cement Concrete .

Please have a look at the section of the Footing as given in the RCC drawing :

The PCC is marked here with Red :

14

Now have a look at the base of a pit . This is how the surface shall be at the base of the excavation :

8

It shall be very clumsy to lay the rebars on such a muddy surface. Right ? Thats why we provide a certain thickness of plain cement concrete here . This concrete is also known as the ” LEVELLING COURSE “.

So the Levelling course is a layer of Plain cement concrete which is given so that we get a good working surface for laying the footing properly. 

Now have a look at the leveling course laid on a site :

12

Next step is to lay the Rebars of the Footings :

15

Parallely , the shuttering for the footing is also fixed on the Levelling course.

13

Now we do casting of the Footing so that it becomes the RCC footing .

16

Hope the first query is clarified.

Now second query pertains to the Water logging during excavation.

You can have a condition like this on the site :

9

So what do we do in such a case ?

Simple.

We have dewatering pumps and take out the water before laying the Levelling course :

10

There might be a case like this also :

6

So now , may be we shall have to wait for a dry spell so that this water either gets absorbed in the soil below or is evaporated.

In a situation , when the excavated pit is not completely dried, it shall not be possible to lay the plain cement concrete in the mud.

What do we do then ?

In such a case , we shall have to do Boulder solling so that we get a good ,

solid working surface .

Look at the stake of Boulders which are also known as Rubble or Stone :

17

These boulders , when laid in the base of a pit , shall look like this :

18

After this , the levelling course is laid in plain cement concrete. This is followed by the RCC footing.

Hope both the queries are clarified now.

Thank you for asking the queries .

Rate Analysis for Gypsum Board Partition

Good Afternoon Readers ,

You shall find an interesting  post here.

So far we have been dealing with the Rate analysis for the RCC , Concrete , Brick work and other such items from a construction site.Correct ?

You can refer to the following link:

Rate Analysis for Brick work 

Today ,we shall address a different item.

What is a complete Item Rate ?

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 :

  1. 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.
  2. 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.
  3. To the subheads 1 & 2 , you shall have to add the following :
    1.  Supervision
    2. Administration
    3. Tools and Plants
    4. Overheads
    5. Contractor’s profit
    6. TDS
  4. 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 .

8

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

3

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 :

India Gypsum 

Henceforth , you need to take the following steps :

  1. Visit the Web page
  2. Contact if there are local dealers/ stockists of the specified product.
  3. Obtain a price list 
  4. Find out if Approved Applicators are available
  5. Obtain a quote from the Applicators 
  6. Arrive at the Complete item rate as explained in the first paragraph of this post.
  7. 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.
