1 Standard specification No.20A requires breaking clods, ramming and sectioning of spoil bank and compacting by watering and consolidation in accordance with TNBP.
2 Standard specification No.20B does not requires breaking clods, ramming, sectioning but require neat banking in accordance with the standard specifications.
3 Double the relevant rate for standard specification No.20B will apply to excavation in all soils and rock classification given above for foundation of buildings, abutments, piers, wings and returns of bridges, culverts, sluices, regulators and cross masonry works, retaining walls, toe walls, cut-off walls and body walls of anicuts, weirs, retaining walls of causeway, bed dams, trenches for water supply and drainage works for laying pipes and sewers, pits and avenue trees, trial pits and pits for poles and towers and toe wall for revetment.
4 An extra 50% over the rate of ordinary excavation in all soils, the rock classification given above shall be allowed for drains, channels and canal having bed width 1.25 metre and below.  The extra percentage is applicable only for depth upto 2 metre; the depth being measured from the bottom of excavation.
5 An  extra  25%  over  the  rate  of  ordinary  excavation  in  all  the  soils  and  rock  classification  given above shall be allowed for drains, channels and canal having bed width 1.25 metre to 2 metre.  The extra percentage is applicable only for depth upto 2 metre.   The depth being measured from the bottom of excavation.
OPEN WELL EXCAVATION
1 Upto  2  metre  diametre  of  wall  10%  excess  will  be  allowed  over  the  basic  rates  of  open  well excavation.
2 The rates do not include bailing charges.  The de-watering is to be done departmentally.  10% of cost  of  excavation  shall  be  allowed  for  de-watering  for  estimate  purpose.   Actuals  (or)  10% wherever  is  less  to  be  allowed  for  de-watering  charges.   For  any  expenditure  above  this percentage, prior approval of the Superintending Engineer should be obtained.
3 For open well excavation for rates upto 12 metre depth, the progress should be X, 2X, 3X, 4X, 5X, 6X and for rates beyond 12 metre depth, the progress should be 8X, 10X, 12X, 14X, 16X & so on.
SINKING OF WELLS
1 For sinking of wells 20% excess will be allowed over the basic rates for wells of diametre 3 metre and above.
2 For well sinking for rates upto 12 metre depth, the progress should be Y, 2Y, 4Y, 6Y, 8Y and 10Y and for rates beyond 12 metre depth, the progress should be 13Y, 16Y, 19Y and so on.
3 The  rates  of sinking  wells  will apply  when  sinking is underwater  at the initial depth itself.  If  water
is  met  with  at  a  lower  depth,  the  rate  applicable  for  open excavation  shall  be  adopted  upto  the depth at which the water is met with.   Beyond  that the rate for the portion underwater  shall be the rate for the previous stage under open well excavation plus 2Y.
4 A  schematic  working  sheet  for  open  well  excavation  and  sinking  of  wells  for  deriving  the  rates  is given below:

 

Open Well Depthinmetes Sinking of Wells
X 2 Y
2X 4 2Y
3X 6 4Y
4X 8 6Y
5X 10 8Y
6X - 12
metre
12 10Y
8X 14 13Y
10X and
so on
16 16Y and so on
Note: X - Basic rate for open well excavation
Note: Y - Basic rate for sinking well
LIFT CHARGES - CONCRETE -  BRECK OR STONE MASONRY  ABOVE OR BELOW GROUND LEVEL
A Concrete above ground level
B Brick or Stone Masonry above ground level
  The extra rates as allowed  for building  works are applicable  to the irrigation  and road works.  The
extra rates may be allowed for the structure beyond 1 metre from ground level
A Concrete above ground level
B Brick  or Stone Masonry  above ground level
  The above extra rates are applicable to building, irrigation and road works.  The extra rates may be
allowed for the structure beyond  1.50 metre from ground level.   (The depth is to be reckoned  from
1.50 metre below ground level).
