(f) Inspection requirement: The fabricated member/component made out of rolled and built-up section shall be checked for compliance of the tolerances given in Table-2. Inspectionof member/components for compliance with tolerances, and the check for deviations shallbe made over the full length.During checking, the inspection requirement shall be placed in manner that local surfaceirregularities do not influence the result.For plate, out of plane deviation shall be checked at right angle to the surface over the fullarea of the plate.The relative cross-girder or cross frame deviation shall be checked over the middle thirdof length of the cross girder of frame between each pair of webs and for cantilever at theend of member.The web of rolled beam or channel section shall be checked for out-of-plane deviation inlongitudinal direction equal to the depth of the section.During inspection, the component /member shall not have any load or external restraint.Inspection Stages: The inspection to be carried out for compliance of tolerances shallinclude but not be limited to the following stages:

i) For completed parts, component/members on completion of fabrication and before anysubsequent operation such as surface preparation, painting, transportation, and erection.

ii) For webs of plate and box girder, longitudinal compression flange stiffeners in box girdersand orthotropic decks and all web stiffeners at site joints, on completion of site joint.

iii) For cross girders and frames, cantilevers in orthotropic decks and other parts in whichdeviations have apparently increased on completion of site assembly.

Where, on checking member/component for the deviations in respect of out of plane prout of straightness at right angles to the plate surface, any other instances, exceedtolerance, the maximum deviation shall be measured and recorded. The recorded


measurements shall be submitted to the Engineer who will determine whether thecomponent/member may be accepted without rectification, with rectification or rejected.

4.0 OILING AND PAINTING:

4.1. No part of the work is to be painted or coated, packed or dispatched until it has beenfinally inspected and approved by the inspecting officer.

4.2. The whole of the work except machined surfaces shall be painted using one of the systemsof painting given below. Prior to painting, the surfaces shall be carefully preparedremoving mill scale, rust, etc, using wire brushes, sander or short blasting as approved bythe Engineer/Inspecting Officer.a) Priming coat:i. The coats of ready mixed Paint red lead priming to IS: 102. ,

ORii. One coat of ready mixed zinc chrome priming to IS: 104 followed by one coat of zincchrome red oxide priming to IS: 2074. The dry film thickness should e 40 microns (Eachcoat of 20 microns)

b) Finishing coats:Two coats of aluminum paint to IS: 2339 shall be applied over the primer coats. One coatshall be applied before the fabricated steel work leaves the shop. After the steel work iserected at site the second coat shall be given after touching up the primer and the covercoat if damaged in-transit. The dry film thickness shall be 3o microns (Each coat of15microns)

4.3 Surfaces which are inaccessible for cleaning and painting after fabrication shall be paintedas specified in before assembled for riveting.

4.4 All rivets, bolts, nuts, washers, etc, are to be thoroughly cleaned and dipped into boilinglinseed oil to IS:77

4.5 All machined surfaces are to be well coated with a mixture of white lead to IS: 34 andMutton tallow to IS: 887

4.6 For site paintings the whole of the steel work shall be given the second cover coat afterfinally passing and after touching up the Primer and Cover Coats, if damaged in- transit.

5.0 TEST AND STANDARDS OF ACCEPTANCEThe materials shall be tested in accordance with relevant IS specifications and necessarytest certificates shall be furnished. Additional tests, if required, shall be got carried out bythe Contractor at his own cost.The fabrication, furnishing, erecting, painting of structural steel work shall be inaccordance with these specifications and shall be checked and accepted by the Engineer.

6.0 MEASUREMENTS FOR PAYMENTThe measurements of this shall be in tones based on the net weight of metal in thefabricated structure computed on the basis of nominal weight of materials.The weight of rolled and cast steel and cast iron shall be determined from the determineshown on the drawings on the following basis:

Rolled or cast steel: 7.84X10-3 kg/cu.cm. Cost Iron: 7.21 X10-3 kg/cu.cm.Weight of structural sections shall be nominal weight.


Weight of weld fillets and weight of protective coating shall not be included.Weight of rivet heads shall be computed by taking the weight of 100 snap heads as given inTable-3.TABLE-3 : WEIGHT OF RIVET HEADS

Dia of Rivets asmanufactured

Weight of 100 snapheads

mm kg12 1.314 2.116 3.418 4.4520 6.122 8.124 10.527 1530 20.533 27.5

The Contractor shall supply detailed calculations sheets for the weight of the metal in thefabricated structure.No additions shall be made for the weight of protective coating or weld fillets.Where computed weight forms the basis for payment, the weight shall be calculated forexact cut sizes of members used in the structure, deductions being made for all cuts,except for rivet holes. Additions shall be made for the rivet heads as mentioned above.

7.0 RATE:The Contract unit rate for the completed structural steel work shall included the cost of allmaterials, labour, tools, plant and equipment required for fabrication, connections, oiling,painting, temporary erection, inspection, tests and compete final erection as shown on thedrawings and as specified in these specifications.

8.0 ELASTOMETRIC BEARING:(I) The elastomeric bearing should be of approved make and should confirm provisions of

UIC-772 R/IRC-83 part I & II specification. It should be fully moulded(II) It should be made of natural or synthetic rubber, should conform railways approved

drawing and should have following properties.Shore Hardness - 60+ 5Shear Modules - 8 Kg/Cm2

(III) Any adhesive used to bond together steel plates and the rubber pads must possess thesame shear strength as that of rubber used. It must also be fully resistant to the action ofoils, weather, atmosphere Ozone, biological agents and extreme temperatures, to whichthe bearings may be subjected.

(IV) The bearing shall have a side cover of at least 6 mm thick elastomer to protect the ends ofsteel plates.

(V) Bearing shall be placed on concrete surface to the correct level and position and bonded tothe surface with approved bonding material. As far as possible the bearings shall be


loaded only when the ambient temperature is the mean of the annual variation oftemperature in that area.
