| 1 | Construction of Granular Sub-base by providing river bed graded river pebbles along with mixing graded aggregate mix to achieve the desired gradation for all leads and lifts, spreading in uniform layers of specified thickness on prepared surface, watering and compacting with earth rammers or suitable compactors of sufficient capacity to achieve required design field density at OMC all complete as per direction and satisfaction of Engineer-in-charge.(Note: - Please read the Technical specifications of the item on before quoting). |
| 2 | Supplying, laying, speading & compacting sand in uniform thickness with three wheeled vibratory/raod roller of 8-10 tonnes capacity, for all height and depth etc. including compaction, carriage of material to work site, for all leads & lifts etc all complete as per directions & satisfaction of Engineer-in-charge. |
| 3 | Demolishing cement concrete manually/ by mechanical means including disposal of material within 50 metres lead as per direction of Engineer - in - charge. Nominal concrete 1:3:6 or richer mix (i/c equivalent design mix). |
| 4 | Demolishing R.C.C. work manually/ by mechanical means including stacking of steel bars and disposal of unserviceable material within 50 metres lead as per direction of Engineer - in- charge. |
| 5 | Earth work in excavation by mechanical means (Hydraulic excavator) / manual means over areas (exceeding 30cm in depth, 1.5m in width as well as 10 sqm on plan) including getting out and disposal of excavated earth, lead up to 50m and lift up to 1.5m,as directed by Engineer-in-Charge. All kinds of soil |
| 6 | Consolidation of sub grade with power road roller of sufficient capacity to attain the maximum density including making good the undulations etc. and re-rolling the sub grade and disposal of surplus earth with lead upto 50 metres. all complete as per satisfaction and Direction of Engineer-in-charge. |
| 7 | Disposal of building rubbish / malba / similar unserviceable, dismantled or waste materials by mechanical means, including loading, transporting, unloading to approved municipal dumping ground or as approved by Engineer-in-charge, beyond 50 m initial lead, for all leads including all lifts involved. |
| 8 | Grading of basic strip of Runway from the ground including removing vegetation and inequalities not exceeding average15cm deep as per the the garding requirements of Civil aviation CAR section 3.4.13 & 3.4.15 using motorized grader/dozer by cutting and filling in 20 cm layers watering and compacting with vibratory roller to obtain desired compacted density as per morth specifications and as per directions of engineer in charge. The work involves taking initial levels and plotting the finished level as per requirement of CAR section 3.4.13 & 3.4.15 and then grading the surface as per the approved gradient.The cut area and filled area should be compacted to desired density as approved by engineer in charge using vibratory roller of 8 to 10 tonnes.vibratory Rollers of smaller widths should be used for areas where bigger rollers can't used. If exra earth is obtained in any sector area,the same to be carried to areas where shortage of earth is there for filling and nothing extra shall be paid for the same. How ever for areas earth is to be brought from borrow pits from outside the AAI premises, the same will be delt under separate item. |
| 9 | Supplying and Banking with good earth obtained from approved quarry (within radius of 10km) in embankment or depression in layers not exceeding 20cm in depth, breaking clods/ over size material, removal of stumps/roots and the like & watering, grading/levelling each layer with dozers/grader and rolling every layer with vibratory roller/ earth compactor of minimum 8-12 tonnes capacity to achieve Min 95% relative compaction (field density) ( as per IS 2720 part VIII) and dressing to the required grade, camber and slope complete as per MoRth specifications and direction of Engineer-in-charge. (The item included cost of wotk, payment of necessary royalty, carriage of good earth upto work site for all leads and lifts involved. Plasticity Index (PI) of the good earth shall not be more than 8, payment to be made for compacted quantity only). |
| 10 | Dismantling of flexible pavement (bituminous courses) by mechanical means and disposal of dismantled material up to a lead of 1 kilometre, as per direction of Engineer-in-charge. |
| 11 | Taking out existing CC interlocking paver blocks from footpath/ central verge, including removal of rubbish etc., disposal of unserviceable material to the dumping ground, for which payment shall be made separately and stacking of serviceable material within 50 metre lead as per direction of Engineer-in-Charge.
