Rate Analysis of PCC : (Plain Cement Concrete)

Rate Analysis of PCC
(Plain Cement Concrete)


     This is used at below any foundation to make a clean and level surface for easy to work, away from sand, dust, mud, etc. This is the temporary structure created to ease your work. PCC is not a Structural Member which can bear any load or pressure. But this plays a very important role when foundation work is going on. PCC will help to keep it as per measurement and as per design.

Sometimes the natural ground has too much uneven surface, in those situations, there is doing Plum concrete. That means 60% of Natural Hard Stone and 40% of Plain Cement concrete will fill with doing some shuttering work to control Size. This will help to create a plain Surface to ease the work.

General Use of Plain Cement Concrete (PCC)

1. Below Footing
2. Below Raft
3. Below Concrete Road
4. Below Grade Slab
5. Below Box type Waterproofing
6. At Labour Camp
7. Work Station of Labour Like Steelyard, Cutting yard, etc.
8. In Godown or Store Room.
9. In Site office.
10. In Plum Concrete at uneven Surface.

In above location, PCC can be done at Normally to work easily.
but What about Plum Concrete Work. Plum Concrete is used at Uneven surfaces to Fill it by Plum Concrete of 60% of Rubble and 40% of Plain Cement Concrete.
sometimes plum concrete can be used at Low bearing capacity soil, but This should be used for small structure not for Building, tower or any big structure because Plum concrete is also not a structural member who can bear load and pressure.

Here we have given some example of Rate analysis of Plum Concrete and Plain Cement concrete (PCC).


Rate Considered: (All Rate is Basic Rate Taxes and Transportation to consider extra)
Cement: Rs. 265.00/Bag
Crush Sand: Rs. 1095.00/cum i.e. Rs. 3100/Brass
Course Aggregate 10mm: Rs. 953.00/cum i.e. Rs. 2700/Brass
Course Aggregate 20mm: Rs. 953.00/cum i.e. Rs. 2700/Brass

Admixture: Rs. 48/Liter up to M25 or Rs. 66/Liter above M30
Labour: Rs. 805/Cum
Extra Overheads: Rs.950/Cum (This cost considered Including Transportation, Shifting, Water Electricity, Housekeeping, PF/ESIC.Etc.)

 In General Condition Lot of builders and Subcontractors are sublating this work on Sqft basis or Per Bag basis to Subcontractor or Concrete gang Who can do it on PCC Rs. 6.00/ Sqft and Plum Concrete in 8.50 to 9.00 Rs. Per Cuft that is 300 Per Cum

What is RERA Area? How to Calculate RERA Area?

Rera Area calculation

In the year 2018, the law is started to bind customer and builders under one law actually this is not first law before that MOFA law is exists but in new law the rules become too strict. and the government is done it's mandatory to all builders, Developers, Promoters, Joint Ventures, that means 
If you are going to build any building for commercial purpose like Residential Apartments, Commercial apartments, etc .you should do the registration under this law. This Law is known as RERA (Real Estate Regulatory Act).

After started this law in real estate there has a lot of misunderstanding and some people's are given negative comments against this law but after some training and information sessions given by RERA authorities, then they changed the mindset of people's as well as Builders.

now, this law is currently smoothly working in India. but need to do some improvement in it. like Case time. Reply timings.etc. But RERA is now improving positively. now will understand some technical details about RERA.

You can find the rules of RERA on his website www.maharera.gov.in. here we are going to understand the actual things about RERA. and Some peoples are doing some mistake and may chance to face some trouble to builder or customer.






Important Rules need to understand before registering in RERA.

1. The builder/promoter shall disclose the following points
1.  land cost in the real estate project.
2.  cost of construction in real estate project.
3. estimated the cost of the real estate project.
4. Disclosure by the promoter of ongoing real estate projects.
5. The promoter of an ongoing real estate project, in which all buildings as per sanctioned plan have not received occupancy certificate or completion certificate, shall be required to submit an application for registration for each such phase of the project, within a period of three months from the date of commencement of the section.
6.Area Loading Calculation for RERA.
Loading %  = Actual Built up Area/ Carpet Area for Sale X 100
Actual built up of building on all floors including refuge area + ground floor area of the staircase, lift, entrance lobby (excluding parking  & terrace floor)/ Total carpet area of all flats is their loading for sale.

Some time observed it is that few so-called studied architects are said to impress the builder as they can give a certificate of more carpet area of your flat than other for the benefit or for more profit or more area which can be beneficial to the builder.

Actually, What are they calculate the area and showing us this is maximum than others.
They are considering external walls without plaster from inside.

but actually internal plaster to external/Outer wall is generally 10 to 20/25 mm and this is to be deducted while considering internal carpet area because wall means brickwork with plaster.
Please be careful while calculating carpet area.

The very important point is Rera does not say to any builder to sale on the carpet. but the builder should have to mention it only. (one can sell on super built-up also).

Another Important point is builder should have to mention carpet in flat purchasers agreement & he /she has the right to check it & pay accordingly while taking possession. This is just opinion subject correction from studied developers.

RERA is applicable to all builder as well as Since Mofa ( Maharashtra Ownership of Flat Act) also exists in Maharashtra So any Builder should not mention any type of built-up area in agreement.

What to Mention in Agreement and How to Sale:


1.  Mention carpet area in agreement saying it’s Rera carpet area and also mention on brochure or cost sheet same area with lumpsum cost but do not mention the built-up area in agreement & brochure.

2)Many developers charge as carpet + 25 to 45 % loading. Few of us don’t do this they work out actually as follows.

Actual built up of building on all floors (excluding parking  & terrace floor) including refuge area + ground floor area of the staircase, lift, entrance lobby divided by total carpet area of all flats is their loading for sale.

Generally, it comes between 30 to 40% depending on the design.

Builders should be work out flat area in this way & multiply it with the rate but, but show & mention everywhere lumpsum cost with Rera carpet area.

3) Sale covered parking. This is a need to correction from experts as per some builders opinion.

HOW RUN BIG CONSTRUCTION COMPANIES?

Currently, in the world a lot of Big projects are running, Like Bridges, Railway, Metros, Roads, Hotels, Townships, Industrial Projects, Airports, etc. These types of projects need too much Manpower and Staff. But all big companies are too Clever because all staff is divided into Different Department which is as follows.


1. Managing Director/ Management.
2. Vice Presidents
3. Project Coordinator
4. Human Resource Department
5. Vigilance Department.
6. Design and Developments
7. Business Development

Below this, They have formed different Departments to Control all staff under one roof and with discipline.


All department are as Follows.

1. Estimation Department
2. Planning Department
3. Contracts Department
4. Billing Department
5. Execution Department : Which is working under Project Manager.
6. Quality Department
7. Purchase Department
8. Store Department
9. Safety Department
10. Electrical Department
11. Mechanical Department
12. IT Department
13. Sales Department
14. Lisining/ Legal Department
15. Account Department
16. Administration Department.


All departments are bonded with each other as per requirements of Management and As per the rule of Standard work procedures to achieve the target or to complete the projects within time.
The Duties are designed as per this Requirement and the Human Resources Department are distributed those duties to everyone with bonding by Salary and facilities.

In this blog, we will study the Structure of those types of companies, which will help you to form your company structure like this. Which can be beneficial to your company in the future.


1. Managing Director:

In Each Company, There is a Key Person Known as " MANAGING DIRECTOR". This the main decision-maker in the company. This person is ideal, innovative, Motivated, and looking always forwarded because he wants to grow his company. and maybe sometimes they have become a business idol.

2. Vice President:

This is the second Key Person of the company who is Managing all the things about the project. He can Control all the Department with proper instructions to give them as per recommend by Managing Director and as per required by Contract or Tender.

3. Project Coordinator :

This person is coordinate the details about projects and update it to his seniors like Vice Presidents after visiting the site and meeting with project Manager, Site Engineer, Etc. He will also Tackle the Contractor issues, Material issues with coordinate with the Purchase and Contract Department.

4. HR Manager: 

This person can bind all the staff under the single roof by giving legal proof of Payment, Attendance Report, Interview arrangement, New staff searching, Salary Sheet formation, Etc. But this person should be like as an Umpire. He needs to keep the balance between Management Requirements, Staff Requirements, and Government rules.

5. Vigilance Department:

This Department is Like in-house Anti Corruption who is always watching the staff activity who is doing corruption in the company like Money Demands to Contractor for approval of Work order, Bill, Measurements, etc. of Commission in Material Rate. This Department is always watching on such activities. But this department is available in only MNC companies.

6. Design and Developments Department:

 This department mostly available in real estate companies because after preparation of all drawing by Architecture some other requirements demand by project location, Management to keep front of Customers requirements, to solve this issue Design and development department is a help. They can calculate the area as per government rules and also doing changes demanded by some customers. They are giv8ng the solutions to architect after finalizing the drawing by management.


7. Business Development:

This Department is directly reporting to Management and Vice Presidents regarding updates about new projects, as well as updates about ongoing projects. They are helping to grow the company graph.
Above Mentioned Department are playing an important role to improve the company performance each year.




Remaining all Department is attached by each other with their job responsibilities which are given by the HR Manager.

HR Manager is bounding all the departments by the organization chart. which is play's very important role to easily understand the role of each person and he will easily know who is my senior and who is the higher authority. as well as he will know who can report him and which are the team members.
The organization chart is like a tree diagram to understand the flow of authorized person and flow of work to update or contact to a particular department and particular person.

Big Construction companies Reporting system in prepared to bound each other and all the staff want to coordinate each other to update themselves. currently, most of the companies are using the ERP:
(ENTERPRISE RESOURCE PLANNING) Which is Computerised program to update and store the data at actual, which can be easily accessible to Management at any time and anywhere?

In the given organization chart we just mentioned the number of posts/ positions to know the exact positions. In actual conditions may change to a different condition like Vice president are more than one, or site engineer/ Supervisors are more than one.

HOW TO PREPARE BAR BENDING SCHEDULE?


HOW TO PREPARE BAR BENDING SCHEDULE?

           After a lot of requests from all audiences from outside India, here we are going to explain the procedure of preparation of bar bending schedule on-site in an easy way, 

           As discussed in our previous blog a lot of fresher’s engineers and some experienced engineers are scared of making bar bending schedule, don’t know about this but they are giving a lot of reasons to keep away from preparing of bar bending schedule to himself.

A lot of Engineers has don’t have any idea about how to prepare Bar bending schedule. for those engineers don't panic, here we will learn about how to prepare bar bending schedule and its format in details, after that you will like preparation of bar bending schedule.

Without going in deep details we will start our subject which is How to prepare Bar Bending Schedule?

 Follow the following procedure to prepare the bar bending schedule efficiently.

1. Detailed Study of Drawing.

This is a very important step before starting any construction work anywhere. No, any work can start and complete without drawing. If any work will start without drawing there may be a lot of mistakes happen and not complete in the proper way.

There are the following types of drawings.
1.       Survey Drawing
2.       Layout Drawing
3.       Architecture Drawing
4.       RCC/Structural Drawing
5.       Plumbing Drawing
6.       Electrical Drawing
7.       HVAC Drawing
8.       Landscape Drawing
And many other types of drawing which depend as per project nature. But those are some important types of drawing but you don’t have all those drawing to prepare bar bending schedule. You need only 2 types of drawing from the above drawings.
1.       Architectural  Drawing
2.       RCC/Structural Drawing

In Architectural Drawing there is details were given about building or any structure like Plans, Sections with all the measurements.

In RCC/Structural Drawing Reinforcement details are given with demarcation of structures like Column is C, Footing is F, Beam is B, etc. and Specifications of Reinforcement of this Structure in Brief. In RCC/Structural Drawing there are 3 Parts and we needed to study. 
1.       Structural Layout
2.       Structural Schedule
3.       General Notes

In structural Layout, Drawing details are given of particular structure, mostly in this drawing given a demarcation of structures as discussed above. Like Footing- F1, Column- C1, Beam-B1, Slab-S1, S2, S3……… etc.
In Structural Schedule there are details of reinforcement is given in brief like
 F1- 5-16mm Dia. (Both side/Top Bottom)
C1- Main Bar- 8-16mm Dia. Stirrups- 8mm 150 C/C

That means, the brief reinforcement details are given for binding steel reinforcement of any type of structure is called a reinforcement schedule. You can easily check the table of reinforcement schedule where is given each and every item reinforcement details.

In General Notes drawings details given about typical structures used in the buildings, as well as section, are given of Footing, Column, Beam and other structures to know how reinforcement will bind and the lengths are given of stirrups, L, lap length, Covers, also mentioned the grade of concrete and other conditions and procedures to follow at the time of execution

2. Prepare a BBS Format

If you are need to prepare bear bending schedule, you understood all the thing to prepare bar bending schedule but if don’t have any idea of how to preset it in the front of client or your seniors. And how they will understand this easily. So fulfill that the entire requirement you need to prepare one good format to separate this entire thing and get the result on one page. Here We are giving a format for Sample, you can follow this or you will change this as per your requirement.
This is the list of Column for preparation of bar bending schedule.

1. Serial Number: Where you can put the serial number of your structures and you can easily count them, it is optional also. This can not affect your bar bending schedule.

2. Item Description: In this Column, you can add the Designation of your structure in Briefly like F1, F2, F3…etc.

3. Numbers: In this column, you can add/insert the same types of structure with the same designation as if Footing F1 is at 8 places shown in RCC Layout drawing then you can add 8 in this column.

4.  Length, Breadth, Depth: Everyone knows about this column you can insert the sizes of your structure which is mentioned in Item description Column in front of this.


5. Quantity: in this column, you can easily calculate the concrete Quantity of your structure by multiplication of Nos X L X B X D: you can easily get concrete quantity, which is helpful for cross-checking of steel constant which we are working here.

6. Bar Description: In this column, we can add the description of the particular bar in briefly you can also add the position of the bar like Bottom Bar, Top Bar, Side Bar, Stirrups, Etc. as per schedule drawing.

7.  The diameter of the Bar. : in this column need to insert the diameter of the bar which is mentioned in bar description as per schedule drawing.

8. Spacing/Nos: In this column, we need to insert the actual spacing of Steel reinforcement as per mentioned in schedule drawing like 12-16Y which means 12 Nos of 16mm Bar. You need to insert 16mm in the Diameter of Bar column and 12 in this column. If there is some stirrups/Link given in column like 8mm@150C/C that means 8mm steel with 150mm spacing.


9. Shape of Bar : You can add the shape of bar as per given in drawing, and give a name to each side to count the length of bar easily in next A, B, C, D, E, F, G, H, I.. column you can insert this length one by one.

10. Total Cutting length: In this column, you can add the Length of A, B, C, D, E, F, G, H, I... column which is needed to insert in this column.

11. Total Number: This column displays the total number of the bar is required in these structure/structures. You can add it by a simple formula like the Total number of Length of Footing divided by Spacing given in Drawing if there is Column you need to do Depth of Column divided by Spacing of Stirrups given in Drawing. And add one every time in it.

12. Weight of Bar: This the main Result of Our Bar Bending Schedule you can see the formula of which is so simple like Total Cutting Length of bars X Nos of Bar X Weight per meter of Bar.
You can see the photo graphs to find out formulas.  


You always need to remember the Weight of Steel per Meter as per this formula.
Weight /Meter: (Square of Diameter meter of Bar)/162
 You will get Following Answers :
1.       8mm : (8X8)/162 : 0.395
2.       10mm: (10X10)/162 : 0.617
3.       12mm : (12X12)/162 : 0.889
4.       16mm : (16X16)/162 : 1.580
5.       20mm : (20X20)/162 : 2.469
6.       25mm : (25X25)/162 : 3.858
7.       32mm : (32X32)/162 : 6.321



If you want more to know about the preparation of Bar bending schedule you need to mail us on director.cbec@gmail.com.
If you require these types of formats you can mail us, we will provide you all types of Formats.

बार बेन्डिंग शेड्यूल कैसे बनाया जाता है?

बार बेन्डिंग शेड्यूल कैसे बना सकते हैं।

                       आजकल बहुत सारे नए और फ्रेशर इंजीनियर को यह एक बहुत बडी समस्या लग रही हैं। इसके साथ साथ कई ऐसे अनुभवी इंजीनियर हैं, उनको आज तक बार बेन्डिंग शेड्यूल बनाना नही आता। इसलिए सभी इंजीनियर को मेरी गुजारिस हैं कि यह एक समस्या नही हैं। आज हम इस ब्लॉग के जरिये समझ सकते हैं कि बार बेंडिंग शेड्यूल बनाना आसान काम हैं। बस थोड़ा ध्यान देना पड़ेगा। तो आइए पता करते हैं कि कैसे आसानीसे हम बार बेंडिंग शेड्यूल बना सकते हैं।


नीचे दिए हुए मुद्दों के जरिये हम बार बेंडिंग शेड्यूल बना सकते हैं।

1. ड्रॉइंग को समझ लीजिये।

बहुत सारे इंजीनियर इस स्टेप को स्किप करते हैं और कही न कही ना कही गलती कर बैठते हैं। और फिर डर जाते हैं कि मुझसे गलती हुई हैं। लेकिन आप कोई भी काम करने से पहले ड्रॉइंग पढ़ना और उसको समझना कभी मत भूले।
कोई भी स्ट्रक्चर बनाने के लिए कई सारे ड्रॉइंग लगते हैं, जैसे,
1. आर्किटेक्चरल ड्रॉइंग
2. स्ट्रक्चरल ड्रॉइंग
3. प्लंबिंग ड्रॉइंग
4. इलेक्ट्रिकल ड्रॉइंग
5. सर्वे ड्रॉइंग

           ऊपर दिए हुए ड्राइंग के टाइप के अलावा भी और भी ड्राइंग रहते हैं। लेकिन आपको बार बेंडिंग शेड्यूल बनाने के लिए, सिर्फ दो टाइप के ड्राइंग की जरूरत होती है। जो हैं आर्किटेक्चर ड्रॉइंग और स्ट्रक्चरल ड्रॉइंग।
आप जब बार बेंडिंग शेड्यूल बनाएंगे उससे पहले ये दोनों ड्रॉइंग को पूरे ध्यान से पढ़िए। 

आर्किटेक्चर ड्रॉइंग से आप सभी मेज़रमेंट को समझ जाएंगे और स्ट्रक्चरल ड्राइंग से आप कंक्रीट स्ट्रक्चर कैसा है यह समझ जाएंगे।

स्ट्रक्चरल ड्रॉइंग के तीन (3) प्रकार होते हैं, 

1. स्ट्रक्चरल लेआउट
2. स्ट्रक्चरल शेड्यूल
3. जनरल नोट्स
                      तिनो भी बहुत महत्वपूर्ण हैं, स्ट्रक्चरल लेआउट से आप कौनसा स्ट्रक्चर कहा पे है यह पता लगा सकते हैं, और स्ट्रक्चरल शेड्यूल से आप कौनसे स्ट्रक्चर को कौनसा बार लगाना हैं और कैसे लगाना हैं यह दिया जाता हैं। और जनरल नोट्स में आपको सभी स्ट्रक्चर जैसे स्टैरकेस, फुटिंग, कॉलम, बीम, स्लैब, छज्जा, लिफ्ट का परदी ऐसे स्ट्रक्चर के टिपिकल ड्राइंग दिए जाते हैं। और साथ मे लैप लेंथ, कवर, एल कितना लेना हैं, स्टिरप का शेप कैसा रहेगा इसकी जानकारी मिल जाएगी।
(उदाहरण: अगर स्ट्रक्चरल लेआउट में कॉलम सी1 का लोकेशन दिया हैं। तो स्ट्रक्चरल शेड्यूल में कॉलम सी1 का साइज 600X300 दिया रहता हैं और आगे 6-16मिमी मतलब 16मिमी के 6 मेन बार लगाना हैं। और 8@150मिमी सी/सी मतलब 8मिमी बार की लिंक और स्टिरप 150मिमी गैप से लगाना हैं।)

2. बार बेंडिंग का फॉरमेट बनाईये।

               ऊपर दी गयी जानकारी को सटीक तरीकेसे समझने के लिए एक फॉरमेट की जरूरत होती हैं जिससे सभी इनफार्मेशन अच्छी तरह से समझ सको और दूसरों को समज़ा सको। इसलिए एक फॉरमेट बनाना चाहिए। जिसमें ऊपर मौजूद पूरी इनफार्मेशन को उसमे दिखाया जा सके। निचे जो फॉरमेट दिखाया हैं यह बस इनफार्मेशन के लिए दिया हैं, आप इसको या इसके जैसा दूसरा भी बना सकते हो। यह एक एक्सेल में बनाया हुआ फॉरमेट हैं। 

3. फॉरमेट को समझकर बनाइये और समझ लीजिए।

१. पहले कॉलम में सीरियल नंबर है। जिससे आपको पता चलेगा कि कितने स्ट्रक्चर है।

२. दूसरे कॉलम में आपको स्ट्रक्चरल शेड्यूल के हिसाब से स्ट्रक्चर का नाम डालना होगा। (उदाहरण: सी1,सी2,सी3..., बी1, बी2, बी3....)

३. तीसरे कॉलम नंबर का हैं जिसमें उसी नाम के कितने स्ट्रक्चर है। एक हैं तो एक, दो हैं तो दो.... जितने स्ट्रक्चर एकसमान हैं उनके नंबर इस कॉलम में डाल सकते है।

४. चौथे, पाचवे और छठे कॉलम में आपको उस स्ट्रक्चर की साइज जो स्ट्रक्चरल शेड्यूल के ड्राइंग में दी गयी है वही इसमे डालनी है। मतलब लंबाई की जगह लंबाई चौड़ाई की जगह चौड़ाई और अभी आर्किटेक्चर ड्राइंग में उस स्ट्रक्चर की ऊंचाई या लंबाई दी जाती हैं वही इस कॉलम में डालके रख सकते हैं। (उदाहरण: 1. अगर कॉलम सी1 की साइज 600 X 300 है तो लंबाई और चौड़ाई में डाल सकते हैं। और ऊंचाई को आर्किटेक्चर ड्रॉइंग में एक फ्लोवर की ऊंचाई 3मी है तो ऊंचाई के कॉलम में डाल सकते हैं। 2. अगर बीम बी1 की साइज 300 X 600 है तो चौड़ाई और ऊंचाई में डाल सकते हैं। और लंबाई को आर्किटेक्चर ड्रॉइंग में देखकर उस बीम की जितनी लंबाई दिखाई है वही लंबाई के कॉलम में डाल सकते हैं।

५. सातवे कॉलम में आप कंक्रीट की क्वांटिटी निकाल सकते है। जो बार बेंडिंग शेड्यूल बनाने में काम नही आती लेकिन बार बेंडिंग शेड्यूल का काम पूरा होने के बाद स्टील का कांस्टेंट देखने के लिए काम आता हैं। मतलब आपने जो बार बेंडिंग शेड्यूल बनाया हैं वो बराबर हैं या गलत हैं यह चेक करने के लिए हम इसका उपयोग कर सकते है।

६. आठवाँ कॉलम हैं बार डिस्क्रिप्शन , मतलब जिस स्ट्रक्चर का शेड्यूल हम बना रहे हैं उसमें कई सारे बार होंगे, तो उसमें जो बार का हम नापी ले रहे हैं उस बार का विवरण इस कॉलम में हम दे सकते हैं जिसका बहुत उपयोग है।

७. नौवे कॉलम में आपको बार का डायमिटर डालना होगा। जिस बार का हमने विवरण लिखा उसी बार का डायमिटर इस कॉलम में लिखना होगा।

८. दसवे कॉलम में बार के नग एवं स्टिरप के बीच का स्पेसिंग कितना हैं यह लिखना होगा।

९. जिसके बाद का कॉलम है शेप ऑफ बार मतलब बार का शेप कैसा होगा। उसको कैसे कैसे बेंड करना पड़ेगा या बेंड किया है। यह एक एक करके कॉलम ए, बी, सी, डी, ई, एफ, जी, एच, आय इस कॉलम में डालके रख दो। और उसमें सब बार का नाप डालने के पहले उसका कवर वजा करो, जैसे 550X300 का कॉलम है तो दोनो बाजूका 40मिमी कवर को वजा करके वो 550-40-40=420 ही लेना पड़ेगा।

१०. अगला कॉलम है टोटल कटिंग लेंथ, मतलब जिस बार का हमने नाप लिया हैं, वो किस शेप में बेंड किया है। उसके अलग अलग मापी को इस कॉलम में आप उस नापी को एकसाथ जोड़ सकते हो। उसके लिए आप एक्सेल का =Sum( L12:T12) यह फार्मूला इस्तेमाल कर सकते हैं।


११. टोटल नंबर के कॉलम में आप को अलग अलग तरीकेसे फॉर्मूलों का इस्तेमाल करना पड़ेगा। जैसे फुटिंग का शेड्यूल बना रहे हो तो और अगर शार्ट साइड के बार ले रहे हो तो लांग साइड को स्पेसिंग से भाग दो और उसमें एक मिलाओ, और उसको नंबर ऑफ फुटिंग से गुणाकर करो तो शार्ट साइड के लिए कितने बार लगेंगे उसका उत्तर मिलेगा।

अगर आप कॉलम के मेन बार का बना रहे है तो, आपको सिर्फ एक कॉलम में कितने बार हैं उसका गुणाकार कितने कॉलम है उसके साथ करना है। आप फ़ोटो में देख सकते है।

अगर आप स्टिरप का नंबर निकलना चाहते है तो, आपको कॉलम की ऊंचाई या बीम की लंबाई को स्टिरप के स्पेसिंग से भागाकार करना है और उसमें एक मिलाना है। आपको कितने स्टिरप लगेंगे इसका उत्तर मिल जाएगा।



१२. इसके बाद आता हैं मेन रिजल्ट मतलब अबतक जो काम किया उसका नतीजा इस आखरी 8 कॉलम में मिल जाएगा। जैसे इसमे आपको एक ही काम करना है जिस डायमिटर के बार का कटिंग लेंथ और नंबर निकाल के रखे थे। उन दोनो आकड़ो का गुणाकार करना हैं। तब हमको एक बार की उस स्ट्रक्चर के लिए कितनी लेंथ होगी ये पता चल जाएगा। उस लंबाई को आप उसके पर मिटर वजन के साथ गुणाकार कर सकते हो। तभी आपको उस स्ट्रक्चर के लगने वाले बार का वजन मिल जाएगा। पिक्चर में दिखाए गए एक्सेल के (=if) के फार्मूले का इस्तेमाल करके आप आसानी से कोई भी स्ट्रक्चर का बार बेंडिंग शेड्यूल बना सकते है।


हर बार का एक मीटर का वजन पता करने का फार्मूला = बार के डायमिटर का वर्ग / 162.
6 मिमी- 0.222 किग्रा/मि
8 मिमी- 0.395 किग्रा/मि
10 मिमी- 0.617 किग्रा/मि
12 मिमी- 0.889 किग्रा/मि
16 मिमी- 1.580 किग्रा/मि
20 मिमी- 2.469 किग्रा/मि
25 मिमी- 3.858 किग्रा/मि
32 मिमी- 6.321 किग्रा/मि

१३. एक (१) क्यों मिलना पड़ता है। हैम जब भी कोई नापी करते है तो 1,2,3,4,5....ऐसे करते है, लेकिन हम जब फार्मूला लगते है तो कंप्यूटर या एक्सेल 0,1,2,3,4,5 ऐसे नापी करता है। (उदाहरण: अपनी 30सेमी की स्केल को ध्यान से देखो, उसमे 30 सेमि दिखता है लेकिन असल मे उसका नापना 0 यानी शून्य से शुरू होता है। ) वैसेही हम जब भी कोई स्ट्रक्चर को स्टील बांधते है तो उस 0 यानी शून्य की जगह भी स्टील बांधना पड़ता है। इसलिए हर बार एक(1) मिलना पड़ता हैं।

१४. बार बेंडिंग शेड्यूल बनाने के बाद उसमें 3% वेस्टेज मिलादो, जो साइट पर एक्स्ट्रा कटिंग हो जाता है। या ड्राइंग में बदलाव के कारण खराब हो जाता हैं।

१५. ग्राउंड +8 मंजिल रेसिडेंशियल बिल्डिंग को साधारण 3 से 4 kg/Sqft इतना स्टील लगता है।

देखा कितना आसान है बार बेंडिंग शेड्यूल बनाना, अभी किसी इंजीनियर को बार बेंडिंग शेड्यूल बनानेसे डर नही लगेगा।
