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. In the event that no rate has been quoted for any item(s), leaving space both in figure (s) or word(s) and the amount blank, it will be presumed that the Tenderer has included the cost of this/ these item (s) in other items and rate for such item (s) will be considered as zero and work will be required to be executed accordingly.
b)
In case of percentage Rate Tender only percentage quoted shall be considered. Any tender containing item rates is liable to be rejected. Percentage quoted by the Tenderer in percentage rate tender shall be accurately filled in figures and words so that there is no discrepancy. If, for any Schedule in Financial Bid, the total amount has been indicated by the Tenderer and if discrepancy is noticed in the percentages quoted in words and figures, then the percentage which corresponds with the total amount, shall, unless otherwise proved be taken as correct. If the total amount is not worked out or if worked out, it does not correspond with the percentages written 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 15

17.7
be taken as correct, unless proved otherwise and the total amount worked out accordingly. 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. (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. The total amount in each Schedule should be written both in figures and in words. 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.) Rs.2.15 P and in case of words the word “Rupees” should precede and the word “Paisa” should be written at the end. Sales-tax/VAT (except Service Tax), purchase tax, turnover tax or any other tax/ Cess on material, labour and Works in respect of this Contract shall be payable by the Contractor and the Employer will not entertain any claim whatsoever in respect of the same. However, in respect of Service Tax, same shall be paid by the Contractor to the concerned department on demand and it will be reimbursed to him by the Engineer-inCharge after satisfying that it has been actually and genuinely paid by the Contractor.
17.8
Each Bidder shall submit only one Bid either as an individual or as a Proprietor in a Proprietary firm or as a Partner in a Partnership firm or as a Director of a limited Company/ Corporation or as a Partner in a Joint Venture. Any Bidder who has submitted a Bid for a work, shall not be a witness for any other Bidder for the same work. Failure to observe the above stipulations would render all such Tenders submitted as a Bidder and / or as a witness, liable to summary rejection.
17.9
The Contractor shall be fully responsible for all matters arising out of the Performance of the Contract and shall, at his own expense, comply with all laws/ acts/ enactments/ orders/ regulations/ obligations whatsoever of the Government of India, State Government, Local Body and any Statutory Authority.

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)
iii)
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. ‘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 39
Signature of the tenderer Under the seal of the firm
department set up by the Central or State Government having powers to investigate. 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.
5.
Suspension of Business Dealings
5.1
If the conduct of any Agency dealing with RITES is under investigation by any department, the Competent Authority may consider whether the allegations under investigation are of a serious nature and whether pending investigation, it would be advisable to continue business dealing with the Agency. If the Competent Authority, after consideration of the matter including the recommendation of the Investigating Department/Unit, if any, decides that it would not be in the interest to continue business dealings pending investigation, it may suspend business dealings with the Agency. The order to this effect may indicate a brief of the charges under investigation. The order of such suspension would operate for a period not more than six months and may be communicated to the Agency as also to the Investigating Department. The Investigating Department/Unit may ensure that their investigation is completed and whole process of final order is over within such period.
5.2
As far as possible, the existing contract(s) with the Agency may be continued unless the Competent Authority, having regard to the circumstances of the case, decides otherwise.
5.3
If the Agency concerned asks for detailed reasons of suspension, the Agency may be informed that its conduct is under investigation. It is not necessary to enter into correspondence or argument with the Agency at this stage.
5.4
It is not necessary to give any show-cause notice or personal hearing to the Agency before issuing the order of suspension. However, if investigations are not complete in six months time, the Competent Authority may extend the period of suspension by another three months, during which period the investigations must be completed.
6.
Grounds on which Banning of Business Dealings can be initiated
6.1
If the security consideration, including questions of loyalty of the Agency to the State, so warrants;
6.2
If the Director / Owner of the Agency, proprietor or partner of the firm, is convicted by a Court of Law for offences involving moral turpitude in relation to its business dealings with the Government or any other public sector enterprises or RITES, during the last five years;
6.3
If there is strong justification for believing that the Directors, Proprietors, Partners, owner of the Agency have been guilty of malpractices such as bribery, corruption, fraud, substitution of tenders, interpolations, etc;
40
Signature of the tenderer Under the seal of the firm
6.4
If the Agency employs a public servant dismissed / removed or employs a person convicted for an offence involving corruption or abetment of such offence;
6.5

ii)
Design Standard: As per West Bengal Fire & Emergency Services recommendation & NBC.
iii)
Min. running pressure: 3.5 Kg. / cm2 required at remotest Hydrant / Landing Valve
1.1.3 DESCRIPTION OF HYDRANT SYSTEM 1.1.3.1 The fire protection system shall consist of pump sets along with necessary instruments, valves, and large network of pipes both underground and over ground which feed pressurized water, to a number of indoor and outdoor hydrant valves, Installation Control Valve and Hose reel. These hose reels, Installation Control Valve and hydrant valves shall be located at different locations throughout the Plant & associated Building complex. 1.1.3.2 The piping network shall be provided with a number of cut-off valves or isolation valves located inside valve pits so that water can be diverted from any damaged section to the point of use such that the availability of the water supply piping network is maintained at high level along with the best possible water pressure at the seat of fire. For meeting the water requirement for hydrant system there shall be one horizontal centrifugal pump. The pump is electrical motor driven only. In addition to the above there shall be one Diesel Engine driven 161
Signature of the tenderer Under the seal of the firm
STAND-BY Fire pump. In case of failure to start the Electric Motor driven Fire Pump or owing to any other reason whatsoever when the Main fire pump does not come in operation the stand by Fire Pump will come in operation automatically through pressure switch and will feed the water in the system. In addition to the above two there shall be one electrical motor driven jockey pump to maintain constant pressure in the supply header. 1.1.3.3 The pumping arrangement as explained above shall serve for the Hydrant system only. Jockey pump shall serve system as explained in the enclosed Drawing. Starting of all the fire pumps shall be automatic but stopping of the pumps, other than the jockey pump, shall be manual. Manual starting/ stopping can be done only from Composite Control Panel located inside the Pump House. 1.1.3.4 Pipelines for hydrant system shall be charged with pressurized water up to the hydrant valves. Small system leakage shall be made up by makeup water supply from the jockey pump installed inside the Pump House. The jockey pump shall be stopped automatically on build-up pressure in the water header. 1.1.3.5 When any of the hydrant valves in the system is opened; water pressure in the water pipe line shall fall rapidly. In such circumstances, the water shall be supplied from the jockey pump to make up for this water loss. But being inadequate to meet the demand, water pressure in the water main shall decrease further and impulse from pressure switch shall start the fire pump through the panel to be located in the Fire Water Pump House. Setting of Pressure switches shall be adjustable so that any desirable sequence of starting may be achieved at site. 1.1.3.6 ALL FIRE PUMPS; JOCKEY PUMP ALONG WITH COMPOSITE CONTROL PANEL ETC. SHALL BE LOCATED IN THE FIRE WATER PUMP HOUSE. 1.1.3.7 In case of fire outbreak, hose pipes fitted with branch pipe and nozzle are to be connected to the hydrant valves / landing valve and then hydrant valves/landing valves are to be opened, and the pressurised water jet is to be directed towards the seat of fire for extinguishments. 1.2 PORTABLE EXTINGUISHERS Portable fire extinguishers will be provided at all working floors of all buildings / plants / substation, and it associated areas at strategic locations and as guided by IS: 2190 – Selection, Installation of First –Aid Fire Extinguishers – code of Practice / Rule No.4.0 of Fire Protection Manual issued by Tariff Advisory Committee (TAC) to arrest small fire at their incipient stages.
