MODES OF MEASUREMENTSGENERAL : Unless specifically mentioned otherwise, the following modes of measurement shall be

adopted.

C-1 Brick Walls :

(a) With Modular Bricks (190 mm x 90 mm x 90 mm) :

The thickness of brick wall made of Modular Bricks with one brick laid flat (with long sideparallel to the length of the wall) shall be measured as 100 mm. One brick thick walls (with thelength of the brick parallel to the thickness of the wall) shall be measured as 200 mm., one andhalf brick as 300 mm, two brick walls measured as 400 mm and so on.

(b) With Conventional Bricks (93/4” x 43/4” x 23/4”) or (248 mm x 120 mm x 70 mm) :

The thickness of brick wall made with one brick laid on edge (with the long side parallel to thelength of the wall) shall be measured as 75 mm. Similarly, a wall made with one brick laid flat(with the long side parallel to the length of wall) shall be measured as 125 mm. 1 brick thick walls(with the length of brick parallel to the thickness of the wall) shall be measured as 250 mm., oneand half brick walls (i.e. one brick along the length and one brick along the width) shall bemeasured as 375 mm., two brick thick walls measured as 500 mm. and so on.

(c) The width of lintels etc. covering the entire thickness of brick wall shall also be measured asequal to corresponding wall thickness.

(d) Net measurement of all wall will be taken after deduction of all opening etc. This applies to 125/100 mm. thick and 75 mm. thick walls also. Parapets (upto 1060 mm. height) will be measuredalong with the brick work of the floor just below the roof and will be paid for at the same rate.

(e) No extra payment will be made for curved or chamfered work even though it may necessitatecutting of bricks. For small curves or chamfers the Engineer-in-Charge may, at his discretionallow measurement on the square (i.e. without deduction for the quantity removed for formingthe small curve or chamfer).

C-2 Concrete Plain or Reinforced :

Finished net measurement will be taken after deduction of large holes, rebates etc. but withoutdeduction for the volume of reinforcement, if any, in the concrete.

B-39

PWD (W.B.), Schedule of Rates

C-3 Reinforcement :The measurement will be on the basis of calculated weight of reinforcement only (i.e. without consideringthe weight of tying wires) actually consumed in the finished work as per drawing and design or as perdirection of the Engineer-in-Charge. If the length of any rod be more than that shown in the drawing buthas been allowed to be used, the length will be taken as the length shown in the drawing. Hooks and lapsas per standard practice will be measured and paid for.

C-4 Plaster, Lime punning, Plaster of Paris rendering :For measurements of plaster (exterior or interior) deduction is to be made for door, window or opening ofsimilar dimension and allowance is to be made for jambs, sills and soffits. Payment will be made on thebasis of surface measurement of wall deducting one-third the measurement of such opening and withoutany separate measurement of jambs, sills and soffits. In case of large openings, exceedling three sq.m.however, as in the case of verandahs with columns, payment will be on actual measurements.

C-5 White Washing and Colour Washing :

(i) Payment will be made on the basis of surface measurement without any deduction for door,window or opening or similar dimension and without any separate measurement for jambs. sillsand soffits of such openings.

(ii) For cement paint and oil painting to walls or concrete jellies or similar other works, method ofmeasurements shall be the same as in plaster.

C-6 Painting :

(a) Measurement for painting work in doors and windows, grills, gratings, collapsible gates, corrugatedroofing etc. shall be on the following basis. In all such cases the “Area” shall be measured flat(and not girthed). For door and windows, no separate payment shall be made for the frames(chowkats), the “Area” in such cases represents the area of the wall opening covered by theframes (including exposed surface of the frames). For grills, gratings etc. the area represents thearea of the opening covered by outer frames.

(b) The area measured as above shall be multiplied by the factor given below and the works ofpainting shall be paid on the quantities thus arrived at :
