1. SCOPE OF WORKS
The work method statement applies to the Roads & Building Construction
2. EXCAVATION WORKS
2.1. Refer to the approved drawings, and check that the layout marking is as per the given drawings.
2.2. Study the soil strata details based on the trial pits and other tests performed at the site.
2.3. Check with the consultant regarding the bearing capacity that is used for design.
2.4. In the case of the foundation, the drawing asks the consultant/architect to issue a foundation drawing incorporating the centre line plan to cross-check the overlapping of the foundation, orientation of the foundation etc.
2.5. Make all the necessary arrangements required like dewatering pumps (of sufficient capacity), shoring arrangement (in case of black cotton soil), vehicles for shifting of materials, safety, electricity etc.
2.6. Get all the approvals required from the local authority for cutting trees, shifting service lines, dumping materials on public property etc.
2.7. Marking is to be done as per the given drawing.
2.8. Check for the orientation of the building with the given north line and the required margins to be left on all sides after the marking is done.
2.9. Once the above is cross-checked start the excavation to the required depth depending on the type of strata and the method to be used as specified in the project's civil specifications.
2.10. Keep the necessary margins to facilitate construction activities.
2.11. Display proper signage and flags to take care of safety measures.
2.12. Note down the levels and bearing capacity at the required given points of the strata and get it approved by the consultant.
2.13. Remove all the loose excavated materials and clean the pit.
2.14. Sufficient lighting arrangements are to be made if the work is to be carried out during the night hours.
3. LEAN CONCRETE
3.1. Check the centre of the pit, its dimension and orientation.
3.2. Check the strata and get them approved by the consultant
3.3. Clean the pit properly by removing all the excavated materials.
3.4. Water the pit and ram it properly to get proper compaction.
3.5. If the surface is uneven do the soling or plum concrete to avoid the excess depth of PCC.
3.6. Prepare the shuttering as per the specified size and place it properly.
3.7. Keep all the materials like cement, sand, and aggregate ready after proper checking.
3.8. Get all the tools and machinery ready by cleaning, washing, lubricating etc.
3.9. Prepare the mix 1:4:8 or 1:3:6 as per the given specification using volumetric batching unless specified.
3.10. Mix the materials (dry) in each proportion till a uniform colour is obtained.
3.11. Add water in the required quantity (w/c ratio) and mix it properly to get a workable concrete.
3.12. Pour the concrete into the required pit using the pans or chute depending on the depth.
3.13. Compact the concrete with the help of a steel rammer or vibrator depending on the depth of PCC.
3.14. The sides of the shuttering should be tamped and finished to get a smooth and uniform finish after de-shuttering.
3.15. Finish the top surface of the PCC to get a uniform finish.
3.16. Mark the centre of the columns on the PCC surfaces the next day.
4. REINFORCEMENT WORK FOR THE FOUNDATION
4.1. Refer to approved drawings and bar bending schedules.
4.2. Steel bars of the required diameter and specification is to be used for reinforcement.
4.3. Cutting of the reinforcements for the footing mesh bars is to be done considering allowance for ‘L’ and covers on all sides.
4.4. Prepare the mesh by tying the bars properly with the help of a binding wire at every junction.
4.5. Cut the column bars to the required length considering the allowance for base ‘L’.
4.6. Cut the bars for rings, single or double as per the requirement of the length accordingly.
2.7. Rings should be prepared on the fitter’s platform, considering the width and the breadth of the column after deducting the cover from the same.
4.8. Footing mesh should be kept in the footing shuttering with the column base tied to its centre, with the binding wire.
4.9. The centre of the footing should be matched with the mesh of the footing.
4.10. The proper cover should be maintained from the sides as well as from the bottom.
5. FORMWORK FOR FOOTING
3.1. After the PCC is done, check for the level and mark the centre of the footing in cement mortar with the help of side rails or centre line pillars.
5.2. Check for the material as per the specification to be used for formwork.
5.3. Place the formwork box and check the size and diagonals of the formwork box.
5.4. Check for gaps if any between the formwork and the PCC top level.
5.5. Before concreting clean the inner space of the box and PCC with the help of a water jet.
5.6. Give proper support to the footing box, so that its position does not change.
5.7. Mark the centre of the footings with the help of a nail, on the footing box or planks.
5.8. The Centre marked on the footing box should match the centre marked on the side rail or centre line pillar.
5.9. Check the reinforcement of footing, column, and concrete depth of footing before pouring the concrete.
6. CONCRETING WORKS
6.1. Refer to the specification of concrete to be used on the project.
6.2. Remove all the loose earth from the bed.
6.3. In case any roots of trees are passing through the foundation must be cut to prevent further growth.
6.4. Check for the proper formwork and reinforcement as per the drawings.
6.5. The ground should be made wet so that water from the concrete is not absorbed.
6.6. If there is any seepage in the foundation trench, then an effective method of dewatering should be adopted before placing the concrete.
7. REINFORCEMENT OF COLUMNS
7.1. Consider floor-to-floor height and lap length 45 diameters to be added into the length (diameter being the diameter of the bar).
7.2. The first cutting of the main reinforcement is to be done.
7.3. Cut the bar for rings of columns depending on the required length.
7.4. For lapping make a joggle if the bar diameter is more than 12mm.
7.5. Prepare the column on the fitter's platform by tying the rings to the main reinforcement if the size & no. of bars are not heavier otherwise erect the column at the required place.
7.6. Shift the column to the slab and erect it in the required position and tie it to the dowels below the floor columns.
7.7. Care should be taken to tie the dowels of the below-floor columns firmly, to the upper-floor columns.
