101 MAHARASHTRA INDUSTRIAL DEVELOPMENT CORPORATION ( A GOVERNMENT OF MAHARASHTRA UNDERTAKING) The quantity of bank shall be paid on the basis of quantity of road cutting used in the bank. The final quantity to be paid for under this item shall be the total quantity of bank work reduced by 1% (one percent) less than quantity to be paid for using the materials from cutting. Item No. 7.:- Watering to OMC (16 kg to 24 kg of water per Cu.M.) The earth work in embankment in 20 cm to 30 cm layers. (95% proctor density). General : The item provides watering the layers of 20 to 30 cm of embankment laid. Material and Equipment : Water to be used shall be free of harmful elements, which may cause heavy efflorescence, etc. and approved by the Engineer-in-Charge. The contractor shall make his own arrangements for getting adequate quantity of acceptable water. The water tankers shall be used, without any additional payment. Watering : When the murum of the 20 to 30 cm layer in embankment road contains less than the optimum moisture, water shall be added to the material in the embankment layers of the road to bring the moisture, uniformly up to requirement. If the material contains more than the required moisture, it shall be allowed to dry until the moisture is reduced to the required extent. If due to wet weather etc. the moisture contents of the soil cannot be reduced to the appropriate amount by exposure, the compaction shall be suspended till suitable conditions prevail without contractor’s claiming any compensation. Item to Include : All material, equipment machinery labour, taxes etc. shall be included in the rate. Mode of Measurement and Payment : The measurement shall be taken on Cum. basis of the embankment of the road watered. Item No. 8.:- Consolidation with proper ramming / rolling in layers the earth work in embankment . (95% proctor density). General : The item provides consolidation of the earthwork in embankment in 20 to 30 cm layers for 8 to 10 tonnes roller and 40 to 50 cm layers for vibratory rollers. This item is to be executed after laying the earthwork in embankment in the layers of 20 to 30 cm and the layer is watered. Equipment : The ramming rods and 8-10 tone ordinary or vibratory roller as directed shall be used. Consolidation : When a loose layer is leveled manually or mechanically with camber provided and moistened or dried to a uniform and required moisture content suitable for maximum compaction, it shall be compacted by power rollers, vibratory rollers or heavy hauling or dozing equipment to give the specified 95% of the standard proctor density. If on testing, the density is found to be less than 95% of the standard density the contractor shall do additional compaction necessary to get the specified density after adding water if required. When the specified density is imperative, the work shall be removed and redone by the contractor at his own cost to give the specified density. Proper sequence of all component operations shall be maintained to give individual progress. For compaction of embankment the road roller shall move longitudinally and rolling shall be done from edges to centre. The camber shall be provided in the cutting and shall not be Contractor.

adjusted in metalling. 102 MAHARASHTRA INDUSTRIAL DEVELOPMENT CORPORATION ( A GOVERNMENT OF MAHARASHTRA UNDERTAKING) Care shall be taken for getting good compaction behind abutments, returns and wing walls, etc. Cutting/ Bank-work in areas not accessible to rollers such as those adjoining bridges, culverts and other works, shall be carried out independently of the main embankment and shall have the layers placed in 10 cm to 15 cm. thickness and each layer shall be moistened and thoroughly compacted with mechanical or manual tampers. Embankment shall be brought up simultaneously in equal layers on each side and compacted carefully to avoid unequal pressure, etc The compaction of the embankment shall be done by moving road roller longitudinally from edges to centre. Item to Include : The item includes only the compaction of each layer by 8-10 tonne roller or vibratory roller. All labour and equipment required to execute the item as per above specification shall be included in the item. If specified vibratory compactors shall be used. Mode of Measurement and Payment : The measurement shall be taken of the earthwork for embankment of road in Cum. upto two decimals. The contract rate shall be for a unit of One Cubic meter of the finished bank work. Item No. 9.:- Filling in plinths and floors with hard murum brought by the contractor from his borrow areas with all leads in 150 to 200 mm layers including watering and compaction etc. complete with all leads and lifts and necessary royalty charges etc complete. General : This item includes all the leads and lifts for filling in plinth and tears with hard murum brought by the contractor from his own barrow areas. The material of filling shall be hard murum or sand and shall be got approved from the Engineer-in-charge before bringing the same at site of work for filling the plinths and floors. Material : The material brought by the contractor shall be stacked separately and classified and approved, as material for filling in plinth by the Engineer-in-charge and the same, shall only be used. The stacked material shall be cleaned of all grass, vegetation and rubbish. The clods of soil shall be broken down to size below 50 mm. Black cotton soil shall never be used for filling in plinth and floor and such clods shall be removed. The material which is not approved by the Engineer-in-charge shall not be used. Method of Work : The ground between the plinth walls shall be first cleaned of all grass, rubbish etc. If directed by the Engineer-in-charge, near the sides of plinth walls special material such as specified graded murum or sand will have to be filled. The material shall be conveyed to the site and spread in 150 to 200 mm layers & shall be compacted with either manual or by mechanical means at O.M.C. for which adequate water shall be used to achieve required compaction. The procedure shall be repeated with each layer, till the required thoroughly compacted level is achieved. Care shall be taken not to damage the plinth constructions and footings below during the process of filling and compaction.
