  NOTES:-        
  1) 10% excess on the above rates will be allowed for the work being executed in side the Jail premises.
  2) Generally Bitumen Emulsion @ 6Kg/10Sqm is to be used in Primer Coat. However, the quantity may be increased as specified in the Contract or as determined by site trials carried out as directed by the Engineer-in-Charge depending upon the porosity.
  3) In case of tack coat, bitumen emulsion / bitumen @ 0.2Kg / Sqm in case of normal bituminous surface, @ 0.3Kg / Sqm in case of granular base treated with primer and
@ 0.4Kg/Sqm in case of granular base (not primed) is to be used
  4) In case of WMM with Wet Mix Plant, BM, DBM, SDBC, BC, open graded PMC, close graded premix surfacing and Seal Coat with Hot Mix plant, carriage of plant mixed
materials from plant site to work site (L) has been calculated as 1Km. distance. This is to be ascertained as per the actual requirement. For example, the distance from quarry to work site is 20Kms, then the lead from quarry to plant may be considered as 5Kms. and from plant to work site (L) as 15Kms. If it is 65 Kms., then the lead from quarry to plant may be considered as 5Kms. and from plant to work site (L) as 60Kms. But in any case, (L) should not exceed more than 60Kms. If the distance from quarry site to work site is 85 Kms., then the lead from quarry to plant may be considered as 25Kms. and from plant to work site (L) as 60Kms
  5) The rates provided for sub-base and metalling is for compacted Cum
  6) For 1 Cum of compacted granular sub-base, 1.28 Cum of loose quantity will be taken into consideration
  7) In case of Built up spray grouting, no extra payment towards cleaning the surface and applying tack coat is to be made as the same has been included in the concerned item.
  8) In case of Primer Coat / Tack Coat to be done by mechanical means, cleaning item is not to be provided separately as the same has been included in the said items.
