Amount

Fencing using Square PCC Fence Posts conforming to product code PCPF-4 at spacing of 10' with Galvanised(G.I) Barbed Wire of 05 strands & 2 Criss-Cross. The fencing work includes cost of fencing material & carriage, both mechanical and head load, loading and unloading, clearance of site, digging of pits of size 1'-6" X 1'-6", fixing of poles in dugout pits upto basal height of 1'-6"as per specification, stretching & fixing of Glavanised Barbed Wire in hooks in 05 strands & 2-Criss-Cross, painting of Fence Posts with enamel paint of approved brand & manufacture as per approved design in green and yellow paint and its numbering, providing & fixing stair/ladder & 01 No. Sign Board of size 3' X 5' with 1mm thick M.S Sheet and 7 feet steel legs including painting and writing as per approved/prescribed specification and design etc. Atleast every 4th fence post along straight line and every fence post at the corner be fixed in a cement concrete block of size 1'X1'X1' 6" in ratio 1 Cement: 3 Sand :6 Stone Aggregate of specified grade.

The DRSM (Dry Random Stone Masonry) work shall be started in small nallahs, gullies etc from top to bottom of the nallah/gully etc. DRSM Works include the cost, collection, carriage of stone to the work site, fashioning of stones to be used along the exposed faces. The front face of the DRSM work is to be mandatorily done with fashioned stone of size not less than 9" in diameter, no DRSM structure shall be more than 15 to 20 in length and 1 meter in Average Height and 1M Width (with a maximum volume of 10 Cum for single DRSM Structure). Proper foundation for DRSM structure should be executed along with provision for apron formation and numbering of all DRSM work is to be done on the biggest stone on the bottom or lower second row of the structure specifying the number of structure as well as year of establishment,(in green and white paint) Calculation of Volume of DRSM work shall be made by multiplying length, width and average height (by taking height from centre, extreme left, extreme height, and then averaging it). 5% Volume shall be deducted from the calculated volume for voids. e.g Length of DRSM Structure = 9Mts. Width of DRSM Structrue = 1Mtr. Average height of DRSM Structure = 1Mtr. Volume of DRSM Structrue =09 x 1 x 1 =09 Cum. Less 5% for Voids = 0.45 Cum. Net Volume = (09-0.45) Cum. = 8.55Cum.
