Session 2 : Excavation Work (Free Online Quantity Survey and Estimation Course)

EXCAVATION WORK

1. Name of Work & Description

Excavation Work is required to prepare the foundation of the building or any structure on a hard surface. Sometimes we need to excavate hard rock also due to level difference, or for road, bridges, need to cut the mountain for tunnel or to prepare roads from the valley.

Before excavation work, we need to find out the SBC (Soil Bearing Capacity) with the help of SBC we can easily prepare or assume how much excavation will be done or what is an approximate depth of our structure foundation.

Types of Ground we are founding when excavation is going on.

1.     Soft Soil

2.     Compacted Soil

3.     Soft Murum

4.     Hard Murum

5.     Soft Rock

6.     Hard Rock

7.     Shade/ Mud Soil

8.     Boulders

2. IS Code No.

IS Code For Excavation Work Code of Safety: IS 3764-1992

IS Code For Sheet Piling Section:  IS 2314:1986

IS Code For Scaffolds & Ladders Code of Safety: 3696: 1991

IS Code for Blasting and Related Drilling Work Code of Safety: IS 4081:1986

3. The Drawing Needs to Read.

Excavation work is needed to do before building or any structure foundation.

The following drawing needs to read before excavation work, or before starting to excavation.

Building Foundation Plan

Bridge Foundation Plan

Plinth Section

Reduced Level Plan

Plot Layout Drawing

4. Location of Work

Excavation can be done with the following Locations.

1. Building Foundation

2. Podium Foundation

3. Basement

4. Under Ground Water Tanks

5. Bridge Foundation

6. Culvert

7. Dam

8. Trench

9. Storm Water Drain

10. Retaining Wall

5. Standard Procedure of Work (Step by Step)

Work Procedure before Start the Excavation

1. Read Plot Layout Drawing Carefully.

2. Read the building foundation Plan and Calculate the building outer to outer measurement.

3. Read Foundation drawing plan, where Footing and A raft of the building are outside than building the line.

4. Calculate Outer to outer distance from foundation drawing of building or bridge structure.

5. Check SBC Report, we need to know what approximate depth of excavation or hard surface is?

6. If Depth of foundation is up to 1.5m then add 1.5m in foundation outer to outer distance both sides.

7. If the Depth of foundation is More than 1.5m then add 3.0m in foundation outer to outer distance both sides.

8. Mark line for excavation as per building outer to outer distance plus 1.5m or 3.0m both sides for foundation workspace.

Example : If Building outer to outer Distance is: 30m X 20m

    Foundation Plan (Footing Size 1.50m X 1.50m ) : 30.00m + 0.75m+0.75m= 31.50m

                                                                                 : 20.00m + 0.75m+0.75m= 21.50m

   Foundation Outer to Outer Distance is = 31.50m X 21.50m

   Now if Depth of Foundation is 4.0m :

   Excavation Size is  :  31.50m + 3.0m + 3.0m : 37.50m

                                  : 21.50m + 3.0m + 3.0m : 27.50m

 9. Check and Note down actual ground level with the help of Auto Level with the same interval of 2m to 5m, Take 4 reading of each interval.

Work Procedure during the Excavation

1. Excavate as per Marking

2. Excavate up to desired height as instructed by a designer with the help of the SBC report.

3. Do not excavate more that limit.

4. Stop when hard strata are shown to responsible peoples.

5. If there is mud or loose soil then us instruction of IS 3764:1992.

6. If excavation is done for a trench or only footing pit then use sheathing with the help of cleat, strut & Wales for support to soil.

7. Barricade the area after the excavation is completed.

8. Check and Note down excavated area levels with help of Auto level by the same interval as you have done during taking an actual ground level reading, Take a minimum of 4 reading of each area.

  

6. Checkpoints

1. Check Machine Capacity as well as which type of machine is Required.

2. Instruct to machine operator regarding the depth of Excavation as well as the size and marking of excavation. As well as show the marking line of excavation.

3. Instruct to Operator to prepare the excavation area angle of 45 degrees of slope.

4. Keep all workers Safe distance from the Machine.

5. If using the breaker to break the rock up to the desired level keep taking reading and level on time to time to avoid extra excavation than required.

6. After Shown, the hard strata arrange the RCC Designer visit to inspect the SBC.

7. Check the Plinth Level and desired level before complete the excavation.

8. Please check Depth of Soling, PCC, Footing/Raft, and Plinth Beam before complete the excavation.

For Example:    If Plinth Level is Given 0.5m Above GL

                        Then Calculate Minimum Excavation Depth

                        Soling for Footing: 0.23m

                        PCC for Footing: 0.15m

                        Depth of Footing: 1.00m

                        Depth of Plinth Beam: 0.6m

                        Then Minimum Depth of The footing is 1.98m below from GL

                        If permission is given by RCC Designer then you can keep the plinth beam and the footing level is the same.

7. Equipment and Machinery

There are two types of excavation is done

1. Manual Excavation

Manual Excavation can be done with the worker by using hand tools like shovels, etc. but for mass excavation can not be possible manually. It will be too costly and time consumable.

2. Mechanical Excavation.

With the help of advance technology excavation is made too much easy and cost-effective as well as time-saving.

The machine is using for excavation

1.     Backhoe Loader (JCB)

2.     Excavator (Poclian)

3.     Mini Excavator (Mini Poclain, Bob-Cat)

4.     Air Compressor Breaker

5.     Poclain/ JCB Breaker

6.     Blasting

7.     Tunnel Cutter

8.     Hywa: For excavated material Shifting

9.     Dumper: For excavated material shifting

10.  Tractor : For excavated material shifting

8. Measurement and Quantity Survey

For the Calculation of the excavated area and quantity of excavated material, we need the following points.

1. Actual Ground Level Reading: Average Level of each interval.

2. Excavated Ground Level Reading: Average level of each interval.

3. Actual Excavated Area: Prepare geometrical shapes as per level interval as we can find an exact excavated area as well as the depth of excavation.

Depth of Excavation = RL of Actual GL – RL of Excavated GL

Quantity of Excavated Area = Actual Excavated Area X Depth of Excavation

Please prepare the chart as per the picture.

9. Checklist

Excavation Work Checkpoints

1. Mark Exact area of Excavation

2. Keep Working space after excavation

3. The slope at edges is 45 degree

4. The sheathing is done or Not.

5. Barricading is done or not to the excavated area.

6. Heavy equipment, such as excavating machinery and road traffic shall be kept back from the excavated sides at a distance not less than the depth of trench or at least 6 m for trench deeper than 6 m.

7.The use of power shovels or draglines in a trench, because of his violent thrust or blows delivered, rapidly render the banks of the trench unstable and dangerous to people working nearby. These conditions shall be watched for and suitably remedied or eliminated.

8. Pathways shall be non-slippery and shall be of adequate width not less than 75 cm. They shall be strong enough to withstand the intended use.

9. Excavation areas shall be adequately lighted for night work.

10. On-site Experience

Readers Experience:  in year 2009, we were work at near thane creek. We know about the ground situation, strata and soil condition also. we started to excavate building foundation which is only one building of one footing, another building has a pile foundation. We completed 80% of excavation and guessed to no need of support to soil or sheathing to side, but we are doing work near to full moon, and during full moon, seawater level is increasing, and our excavator machine is parked at same place where excavation is going on, on next day morning we all has shocked, machine is going under the water. We had tried to out from this area but the machine is clogged due to mud. After too much struggle we escape this machine from this area.

4. Mark 1 point on sheet where plum bob is spotted.
5. Now you can start the survey, 1st take the measurements of 0 point to building corner or Compound wall corner. after focus by crosshair on corner of building or corner of compound wall  With the help of scale draw the line and convert this line in 1:10 scale i.e. if distance is 100 meter you need to draw the line 10 cm. mention scale on right side bottom of drawing with date.
6. Focus on all visible and draw the line as per previous procedure.
7. close the survey after completed all drawing.

2. Dumpy Level/ Auto Level Survey

1. Set the Dumpy /Auto Level on Tripod
2. Level it, measure the height of Dumpy/Auto Level with the help of tape.
3.With the Help of Staff take the reading at 1st point which RL is known to you. which is Back sight.
4. Then take all the staff reading and note down as per given format.
5. If you want to shift the Dumpy/Auto Level Please take last reading again.
6. After taking all points reading please close the survey after taking first point reading.
7. Dumpy/Auto level work in X Y axis, ie only Horizontal axis.

3. Total Station/Theodolite.

Both are different but result is same
1. Fix the Total station on tripod in known point whose coordinate are already known.
2. Level it horizontally and Vertically. (This will take little bit time)
3. input all the points coordinate in the Total Station
4. now with the help of prism mark the exact point of your co ordinate.
5. Total Station/Theodolite is work in X Y and Z axis, i.e
Horizontal and vertical axis.

6. Checkpoints.

5. HI : Height of Instrument. RL+BS= HI
6. Next point RL = HI- IS
7. Last Point RL = HI - RL
8. Please take all Reading on 10mx10m Interval after that we can create contour drawing.
9. Connect the all points on a same RL is called contour line, which is showing ups and downs in ground.

Plain Table Survey

1. After creating a drawing as per above procedure.
2. Make geometric shapes on drawing by pencil.
3. Mark those area 1, 2, 3 , 4 , 5 etc.
4. Write the value as per area. like if triangular shape write 1/2×base x height, etc.
5. Calculate the area as per all shape, use right formulas for shape.
6. After calculate all area add it. and multiply it by 100 times or what ever you have assumed the scale while survey, for that you can check the drawing.
7. This is your plot area.

Total station survey

1. This is automatically check all the point and export it in Autocad software.
2. As we discussed is Contour survey,
3. On this principal Total station is working and giving you directly output of drawing of given points as well as contour line.
4. This is big discussion point we will discuss on it after this course. if any one want please drop us Mail.

9. Check list:

Dumpy Level/Theodolite/Total Station/Auto Level.

1. Set Tripod at on ground, where you can cover by maximum area visibility.
2. Connect dumpy level/Auto level to tripod, fix and tight it properly.
3. Now adjust tripod on assumed point, and keep it in level.
4. Level the instrument with the help of bottom screw, level is visible at spirit level bar.
5. Turn 90° of instruments with last adjusted level, one one screw adjust the level.
6. After reading All RL calculation should be cross check.
7. Before prepare drawing convert it in proper scale.
8. When draw the line on paper please keep exact measurements on scale ratio.
9. Use good and Sharp pencil while doing plain table survey, which is helpful for Exact measurements.
10. While plain table survey, Fix drawing on exact center, and don't remove it until survey is complete.
11. While total station survey keep one battery in spare, there are main issue of battery discharge while big plot survey.
12.Calibration Report of Total station/Dumpy Level/ Auto level/Theodolite, etc.

10. On site Experience:

Readers Experience : In Mumbai while surveying a plot one major problems we faced regarding the theodolite,Ground level different is more than 6 meter so we can't use line as well as diagonal by tape, so that time we used theodolite, but due to some calibration issues in theodolite, All point are given us by us is Wrong and shifted by 75mm. all columns are need to do jacketing due to that issue, so guys please update your instruments on time and do calibration from good agency periodically. Thank you.

All Above data is available on the Green Building Website, you can visit and get the detailed information about it.

Now we will discuss what type of resources need to use in Green building.

Resources Required

1 Recycled Aggregates to be used in Concrete. 

If Possible Need to use recycled concrete for nonstructural members like Fins, Chajjas, Lintels, Patli, Bund Wall, Etc.

2 Fly Ash Bricks or AAC Block Work.

Do not use Clay bricks. instead of use AAC blocks or Fly ash bricks.

3 Cavity Wall with Insulation, DGU system for Glazing having U Value at 1.5.

4 Two wind Tower (18m Height) with drizzling water tank on top to get cool air down and the same air is used for the cooling system of the AC plant. One tower calibrated as 10T AC Capacity.

5. Solar Water System

Need to install a solar water heating system at the rooftop of the building which is dependent on natural resources and saving energy.

6. Terrace with garden to provide roof insulation. 

Terrace gardens will be useful both ways like prevent from heat and saving of space, which can be used at the ground and might be cut the trees.

7. Recycling of water for flushing and gardening. 

Use of Sewage treatment plant and recycle all the water for flushing and gardening.

8. Rainwater harvesting and rainwater collection tank for drinking. 

With the help of the Sand filter, you can easily filter rainwater from building rooftop and collect it in the drinking water tank.

9. The orientation of building to sync with sunlight, shadow and wind flow.

 All Door and Windows Opening designed accordingly east, west and south, north side as well as per wind flow which can be useful to maintain the room temperature in level in each weather.

10. Vermicompost pit. 

This is mandatory to all society and apartments but people are not using the property. This is very useful and vermicompost pit can give us good organic fertilizer and which is used at all the trees in society premises.

11. Use Local Material where possible.

The use of local material is cost-effective as well as little fuel consumption. 

12. Avoid Extra cost for Decoration/ View/ Elevation.  

Minimalism principle to be used. uses natural looks do not go with fancy and decorative items that are made after damage nature. avoid extra elevation treatment like fins, glass, etc. 

13. No wastage of space in building for fantasy.

Use all the space in building premises, don't waste the space to make more decorative. instead of decoration, you can plant the trees in open areas.

14. Avoid Wood

Please avoid all types of wood items which is made after damage. instead of wood, you can use other recycled materials. like instead of wooden frames, use concrete frames.etc.

15. Less use of Electricity

Prepare building/home plan as per efficient natural lighting which is helpful to keep ventilation in-home and less use of electricity.

16. Use non-toxic paint etc.

Toxic paint is made from hazardous chemicals and at the time of application, they are spreading poisons fume or smells in the air, which is harmful to human beings as well as nature.

Use very sustainable material so your building last of ever. like a brick lime mortar.

nowadays considering span and space constraint difficult to use the thick brick wall and lime mortar so used concrete shall be sustainable.

वॉटरप्रूफिंग के लिए तोड़फोड़ करने से पहले करे ये काम, नही तो होगा नुकसान।

वॉटरप्रूफिंग के लिए तोड़फोड़ करने से पहले करे ये काम, नही तो होगा नुकसान।

जब किसी के घर मे लीकेज शुरू होता हैं। तो पहले वो मेंटली डिस्टर्ब हो जाता हैं। हर किसी का ऐसा ही हाल होता हैं। उसके बबाद सबसे बड़ा खतरा यह होता कि। लीकेज हैं तो हैं कहा। अगर उसको ढूंढना हैं तो सब तोड़फोड़ करना पड़ेगा। तोड़फोड़ करना मतलब सब काम को दोबारा करना पड़ेगा। पैसे की बर्बादी होगी। हर एक बंदे के मन मे यही खयाल आता हैं।

लेकिन आज हम कुछ ऐसे विषय पर बात करनेवाले हैं जिससे आपको कम से कम 70% से 90% तर फायदा होगा। और नुकसान भी कम होगा। तोड़फोड़ भी कम होगी, और मटेरियल, टाइम की बचत होगी।

अगर आपका घर या फ्लैट 10 साल तक पुरानी सोसायटी में हैं तो सोसायटी के डेवलोपमेन्ट करनेवाले बिल्डर को संपर्क करे, और उनसे उस वॉटरप्रूफिंग कांट्रेक्टर का 10 साल या 5 साल की गारंटी के बारे में पूछ लीजिये, और उसी कांट्रेक्टर से रिपेयर करने की कोशिश करिये। लेकिन आपका लीकेज इंटीरियर या आपके किसी गलती या बदलाव करने से नही होना चाहिए। अगर ऐसा रहेगा तो ओ आपसे अलग पैसे लेगा।

अगर आपकी सोसायटी 10 सालसे ज्यादा पुरानी हैं तो आपको सब खर्चा करना पड़ेगा। क्योंकि आपके इमारत या बंगलो की वटरप्रूफिंग की गारंटी खत्म हुई हैं। अब आपको वॉटरप्रूफिंग कांट्रेक्टर ढूंढना पड़ेगा। इसलिए आप हमारे वेबसाइट www. cbecindia.com/contractor पे आपके मनचाहा कांट्रेक्टर ढूंढ सकते हैं। और दिए गए कांटेक्ट नंबर के ऊपर फ़ोन करके उनसे कोटेशन मंगवा सकते हैं।

अगर अपने आपके घर में हो रही पानी की लीकेज बंद करने के लिए कांट्रेक्टर ढूंढ लिया है। तो आपको अभी आगे कि सभी स्टेप ध्यान से पढ़नी पड़ेगी।

कैसे भी करके लीकेज को तो बंद करना पड़ेगा। सबसे पहले आपको पता चलना चाहिए ना, की सच मे लीकेज कैसे ढूंडा जा सकता हैं। कुछ ऐसी चीजें हम बताने वाले हैं उसके बाद आप खुद चेक कर सकते हैं कि असल मे लीकेज कहा हो सकता हैं।

नीचे कुछ ऐसे पॉइंट दिए हैं, जिससे हम आसानीसे से लीकेज ढूंढ सकते हैं। और उसको काम से कम खर्चे में रिपेयर कर सकते हैं।

लीकेज के 6 प्रकार के होते हैं।

1 इनलेट पाइप से होनेवाला लीकेज:

इस प्रकार के लीकेज में एकबार लीकेज सुरु हो गया तो वो बंद नही होता। बढ़ता ही रहता हैं। अगर लीकेज दीवार पे दिख रहा है तो पूरी दीवार गीली दिखती है। या कहिसे पानी टपकता हैं तो वो बंद नही होता है। 24 घंटे टपकता है। इसप्रकार के लीकेज ज्यादातर इनलेट मतलब जिस पाइप से पानी अंदर आता हैं उसी में होता हैं। कभी कभी ओ पाइप क्रैक होता है या ज्यादा प्रेशर की वजह से जॉइंट लूज होते हैं। और वही से पानी आता हैं। इसमे शॉवर, गीज़र, बेसिन में आनेवाले पानी के पाइप का नाम आता हैं।

2 आउटलेट पाइप से होनेवाले लीकेज:

इस प्रकार के लीकेज में जहां से लीकेज हो रहा हैं वह जगह कभी गीली और कभी सुखी हो जाती हैं। जहासे पानी टपकता हैं वह कभी चालू होता हैं और कभी बंद हो जाता हैं। मतलब लीकेज हर बार नही होता है। इस प्रसार के लीकेज पानी का इस्तेमाल करने के बाद बाहर जाने वाले पाइप में रहता हैं। इसमे बाथरूम का ट्रैप, बेसिन का आउटलेट, कमोड का पाइप का नाम आता हैं।

3 ट्रैप को चेक करके देखना : 

बाथरुम में पानी छोड़के नहानी ट्रैप को साफ करके नहानी ट्रैप को अंदर साइड में बैटरी से चेक करें। उसमे अगर कोई छेद होगा। तो वही लीकेज का कारण हो सकता हैं। आप कोई प्लम्बर या लेबर को बोलके उस होल या छेद में वटरप्रूफिंग केमिकल भर के फिनिशिंग कर सकते हैं।

4 पाइप के जॉइंट के जगह चेक करना:

जब भी लीकेज होता हैं। उसका यह एक कारण हो सकता हैं। पाइप के जॉइंट लूज होंगे तो लीकेज शुरू हो सकता हैं। अगर जी आय की प्लंबिंग हैं। तो कुछ साल बाद यह प्रॉब्लम जरूर आति हैं। पाइप के जॉइंट की जगह जब गीलापन दिखेगा तो उस जहन की टाइल निकालकर रिपेरिंग कर कर सकते हैं।

5. टाइल के जॉइंट चेक करना:

अगर सब सही दिख रहा हैं। फिर भी पानी का गीलापन दूसरे रूम की दीवार पे दिख रहा हैं। तो कभी कभी टाइल के जॉइंट से भी पानी की लीकेज हो सकती हैं। उस टाइप की लीकेज जब बाथरूम का इस्तेमाल करते हो उसके बाद दिखती हैं, और 3-4 घंटे बाद फिर वो दीवार सुख जाती हैं। उस समय आप टाइल के जॉइंट भी चेक करके ले सकते हैं। अगर उनमे कई जगह पर जॉइंट खुले और उल्हदे हुए लग रहे हैं। तो आप उसमे व्हाइट सीमेंट और वॉटरप्रूफिंग केमिकल इस्तेमाल कर सकते हैं। आजकल बाजार में बहुत अच्छे वॉटरप्रूफिंग केमिकल मिलते हैं। आप सीधा उनका भी इस्तेमाल कर सकते हैं।

6. स्कैनर मशीन से लीकेज चेक करना:

यह एक नए जमाने की तकनीक हैं। जिसपर हम 100% फीसदी भरोसा कर सकते हैं। यह एक ऐसा स्कैनर हैं। जो आपको सटीक तरीके से लीकेज की सटीक जगह बताता हैं। यह मशीन आपके हर एक दीवार, फ्लोर को स्कैन करती हैं। उसके बाद आप आसानीसे उस जगह की रिपेरिंग कर सकते हैं।

ऊपर बताये तरीके से ढूंढने के बाद आप उसी पाइप या जगह  को आसानी से ढूंढ सकते हैं। उस जगह का टाइल निकालके पाइप को खुला करके रिपेयरिंग कर सकते हैं।

अगर इनमेसे कोई भी नुस्खा काम न करे तो अच्छे वॉटरप्रूफिंग कॉन्ट्रेक्टर से संपर्क करे। या नीचे दी गयी वॉटरप्रूफिंग केमिकल बनानेवाली कंपनी के साथ संपर्क करे। और साथ मे उनके प्रोडक्ट की गारंटी की पूछताछ करे। साथ मे क्वालिटी के रिपोर्ट की मांग करें। गारंटी के पेपर आपके पास रखें। काम शुरू करने के पहले उस कांट्रेक्टर को वर्कआर्डर दे, उसमे गारंटी, क्वालिटी, मटेरियल का नाम, और टाइप, केमिकल बनानेवाली कंपनी का नाम, काम शुरू करने की तारीख, काम पूरा करने की तारीख यह सब विवरण के साथ कांट्रेक्टर को वर्क आर्डर दे दो।
