PART 6 VENTILATION PIPES AND OTHEREMBEDDED MATERIALS

o. FOR E W 0 R D

0.1 This Indian Standard (Part 6) was adopted by the IndianStandards Institution on 1·1 December 1984, after the draft finalized bythe Measurement of Works of River Valley Projects Sectional Committeehad been approved by the Civil Engineering Division Council.

0.2 In measurement of quantities, in construction of river valley projectsa large diversity of methods exists at present according to local practices.This lack of uniformity creates complication regarding measurementsand payments. This standard is intended to provide a uniform basis formeasurement of ventilation pipes and other embedded materials in theconstruction of river valley projects.

0.2.1 The provisions contained in this standard shall generally haveprecedence over the provisions in IS : 1200 (Part 2 )-1974*. However,the provisions of both the standards Inay be considered complimentaryand supplementary to each other.

0.3 In reporting the result of measurement made in accordance with thisstandard, if the final value, observed or calculated, is to be rounded off,it shall be done in accordance with IS : 2-1960t.

1. SCOPE

1.1 This standard (Part 6) covers the method of measurement ofventilation pipes and other embedded material in river valley projects,such as dams, hydraulic structures, canals and power houses.

• Method of mealurement of building and civil engineering works: Part 2 Concreteworks ( ,hi,d ""is.. ).

tRules Cor rounding off numerical values ( ",,",4).

2. GENERAL

2.1 ClubbiDg or Items - Items may be clubbed together providecthese are on the basis of the detailed description of items stated in thitstandard,

2.2 BooklDg or Dlme••loas - In booking dimensions, the order shanbe consistent and generally in the sequence of length, breadth or widthand height or depth or thickness.

2.3 Deserlptioa of Items - The description of each item shall. unlessstated otherwise, be held to include where necessary, conveyance anddelivery, handling, loading, unloading, storing. fabrication, hoisting,lowering, all labour for finishing to required shape and size.

2.4 Mea8aremeDts - All works shall be measured net in decimalsystem, as fixed in its place as given in 2.4.1 and 2.t.2.

2.4.1 Dimensions shall be measured to the nearest 0·01 m,

2.4.2 Weight shall be worked out to the nearest 0'01 kg.

3. MEASUREMENT OF PIPES AND EMBEDDED MATERIALS

3.0 Items included in this standard are as follows:

a) Ventilation pipes;

b) Grout pipes;

c) Foundation, drainage/uplift pressure pipes;

d) Internal drainage pipes in dams;

e) Sewer pipe drains;

f) Metal pipes embedded for post-cooling concrete;

g) Steel liners for air-vents, plumb bob wells) etc;

h) Embedded parts for trashracks, control gates, etc, steel ladders,metal hand rails, manhole frames, covers and other mis­cellaneous metal work;

j) Electrical metal conduits; and

k) Anchor rods, anchor bolts.

IS I 9401 ( Part 6 ) • 1184

the quality of pipe, kind of material and the method of jointing and shallbe measured in running metres, inclusive of all joints. The measure­ment shall be taken along the central line of the pipes and fittings orspecials. All fittings or specials shall be enumerated separately as extraover the pipes. Cutting and jointinz the pipes to such fittings or specialsshall be deemed to be included with the item of fittings or specials.

3.2 lateraal Draiaage Pipes in Dams - Measurement for porousconcrete pipes shall be on the basis of the length of pipe in metre laid inthe body of dam. The nominal diameter and type of the pipe shall bespecified.

3.3 Sewer Pipe DraiDs - Measurement for perforated sewer pipe andconstructing drains shall he made in metres along the centre lines of thepipe, fro III end to end of the pipe in place and no allowance shall bemade for laps at joints. The nominal diameter and type of the pipeshall be specified.

3.4 Metal Pipes Embedded for Post-Cooling of Mass CODcrete­The pipes shall be classified according to their nominal diameter, thequality of pipe, kind of material and the method of jointing and shall bemeasured in running metres, inclusive of all joints. The measurementshall be taken along the central line of the pipes and fittings or specials.All fittings or specials shall be enumerated separately as extra over thepipes. Cutting and jointing the pipes to such fittings or special. shall bedeemed to be included with the item of fittings or specials.

. 3.5 Steel Liners for Air-Vents, PlulDb Bob Wells, etc - Measure­ment for the lining plates and other structural steel shall be on the basisof mass in kilograms of plates and structural steel actually embedded inthe structure.

3.6 Embedded Parts for Trashracks, Control Gates, etc, SteelLadders, Metal Hand Rails, Manhole Frames, Covers aDd OtherMiscellaneous Metal Work - Measurement for these items shall he onthe basis of weight in kilograms of metal work actually installed and leftin place.

3.7 Electrical Metal Conduits -. Measurement for various types andsizes of electrical metal conduit shall be on the basis of length in runningmetres of conduits, actually embedded in the structure.

3.8 Aachor Rods, Aachor Bolts - Measurement for anchor rods andanchor bolts shall be made on the basis of weight in kilograms of anchorbolts or anchor rods actually embedded. In case of anchor bolts theweight shall include the weight of bolt, nut, washers, wedges and bearingplates.
