However, if a discrepancy is found, the rates which correspond with the amount worked out by the Tenderer shall unless otherwise proved be taken as correct. If the amount of an item is not worked out by the Tenderer or it does not correspond with the rates written either in figures or in words then the rates quoted by the Tenderer in words shall be taken as correct. Where the rates quoted by the Tenderer in figures and in words tally but the amount is not worked out correctly, the rates quoted by the Tenderer will, unless otherwise provided, be taken as correct and not the amount.

If the total amount is not worked out or if worked out, it does not correspond with the percentages written


16

either in figures or in words, then the percentage quoted by Tenderer in words shall be taken as correct. When the percentages quoted by the Tenderer in figures and in words tally but the total amount is not worked out correctly, the percentage quoted by the Tenderes shall be taken as correct, unless proved otherwise and the total amount worked out accordingly.

17.5 In the case of any Item rate tender where unit rate of any item/items appears unrealistic, such tender will be considered as unbalanced and in case the Tenderer is unable to provide satisfactory explanation, such a tender is liable to be disqualified and rejected.

17.6 (a) In Item rate Tender, all rates shall be quoted on the tender form. The amount for each item should be worked out and requisite totals given. Special care should be taken to write the rates in figures as well as in words and the amount in figures only, in such a way that interpolation is not possible.

In case of figures, the word ‘Rs.’ should be written before the figure of rupees and word ‘P’ after the decimal figures, e.g. Rs.2.15 P and in case of words, the word, ‘Rupees’ should precede and the word ‘Paise’ should be written at the end. Unless the rate is in whole rupees and followed by the word ‘only’ it should invariably be up to two decimal places. While quoting the rate in schedule of quantities, the word ‘only’ should be written closely following the amount and it should not be written in the next line.

(b) In Percentage Rate Tender, the Tenderer shall quote percentage below / above (in figures as well as in words) at which he will be willing to execute the work. He shall also work out the total amount of his offer and the same should be written in figures as well as in words in such a way that no interpolation is possible. In case of figures, the word “Rs” should be written before the figure rupees and word ‘P’ after the decimal figures (eg.)

ANNEX-A Guidelines on Banning of Business Dealings

1. Introduction 1.1 RITES, being a Public Sector Enterprise and ‘State’, within the meaning of Article 12

of Constitution of India, has to ensure preservation of rights enshrined in Chapter III of the Constitution. RITES has also to safeguard its commercial interests. It is not in the interest of RITES to deal with Agencies who commit deception, fraud or other misconduct in the execution of contracts awarded / orders issued to them. In order to ensure compliance with the constitutional mandate, it is incumbent on RITES to observe principles of natural justice before banning the business dealings with any Agency.

1.2 Since banning of business dealings involves civil consequences for an Agency concerned, it is incumbent that adequate opportunity of hearing is provided and the explanation, if tendered, is considered before passing any order in this regard keeping in view the facts and circumstances of the case.

2. Scope

2.1 The procedure of (i) Suspension and (ii) Banning of Business Dealing with Agencies, has been laid down in these guidelines.

2.2 It is clarified that these guidelines do not deal with the decision of the Management not to entertain any particular Agency due to its poor / inadequate performance or for any other reason.

2.3 The banning shall be with prospective effect, i.e., future business dealings.

3. Definitions

In these Guidelines, unless the context otherwise requires:

i) `Bidder / Contractor / Supplier' in the context of these guidelines is indicated as ‘Agency’.

ii) ‘Competent Authority’ and ‘Appellate Authority’ shall mean the following:

a) The Director shall be the ‘Competent Authority’ for the purpose of these guidelines. MD, RITES shall be the ‘Appellate Authority’ in respect of such cases.

b) MD, RITES shall have overall power to take suo-moto action on any information available or received by him and pass such order(s) as he may think appropriate, including modifying the order(s) passed by any authority under these guidelines.

iii) ‘Investigating Department’ shall mean any Department, Division or Unit investigating into the conduct of the Agency and shall include the Vigilance Department, Central Bureau of Investigation, the State Police or any other department set up by the Central or State Government having powers to investigate.


39

4. Initiation of Banning / Suspension:

Action for banning / suspension business dealings with any Agency should be initiated by the department/ unit having business dealings with them after noticing the irregularities or misconduct on their part.

All field assembly and welding shall be executed in accordance with the requirements for shop assembly and welding. Holes for all erection bolt – where removed after final erection shall be plugged by welding. Alternatively erection bolts may be left and secured.

15.0 GROUTING

15.1 Prior to positioning of structural columns/girders/trusses over the concrete pedestals/columns/brackets, all laitance & loose material shall be removed by wire brushing & chipping. The bearing concrete surfaces shall be sufficiently leveled, hacked with flat chisels to make them rough, cleaned (using compressed air) and made thoroughly wet. All pockets for anchor bolts shall also be similarly cleaned and any excess water removed. Thereafter, the structural member shall be erected, aligned & plumbed maintaining the base


106

plates/shoe plates at the levels shown in the drawings, with necessary shims/pack plates/wedges.

15.2 After final alignment and plumbing of the structure, the forms shall be constructed all round and joints made tight to prevent leakage. Grouting (under the base plates/shoe plates including grouting of sleeves & pockets) shall be done with non-shrink grout having compressive strength (28 days) not less than 40N/sq.mm. Non shrink grout shall be of free flow premix type and of approved quality and make. It shall be mixed with water in proportion as specified by the manufacturer. Ordinary 1:2 cement/sand mortar grout shall be used only for small isolated structures e.g. operating platforms not supporting any equipment, pipe supports, cross overs, stairs and ladders. The thickness of grout shall be as shown on the drawings but not less than 25 mm nor more than 40mm in any case.

15.3 The grout mixture shall be poured continuously (without any interruption till completion) by grouting pumps from one side of the base plate and spread uniformly with flexible steel strips and rammed with rods, till the space is filled solidly and the grout mixture carried to the other side of the base plate.

15.4 The grout mixture shall be allowed to harden for a period as decided by the RITES and /or Engineer-in-charge of SAIL-RITES BWIPL. At the end of this period, the shims/wedges/pack plates may be removed and anchor bolts tightened uniformly. The alignment of the structure shall now be rechecked and if found correct, the voids left by the removal of shims/wedges/pack plates (if removed) must be filled up with a similar mixture of grout. In case after checking, serious misalignment is indicated, the grout shall be removed completely and fresh grouting done after making appropriate correction of alignment.

16.0 SCHEME AND SEQUENCE OF ERECTION

The Contractor shall furnish the detailed scheme and sequence of erection to match with the project schedule and get the same approved by the RITES and /or Engineer-in-charge of SAIL-RITES BWIPL.
