IMPORTANT POINTS FOR THE GUIDANCE TO THE
FIRMS/CONTRACTORS INTENDING TO SUBMIT TENDERS
1.0 Usually the firms/contractors are in the habit of giving too many conditions in their
offer. According to the conditions in the “NOTICE INVITING TENDERS”, the
tenders with conditions are liable for rejection.
The tenderers are therefore,
advised to submit the tenders without their own conditions. In case, they consider
some conditions are necessary they are requested to give clear cut, financial
implications of each of such conditions to facilitate proper comparison of the
tenders.
2.0 The tenderers are required to see that their tenders are in conformity with the
conditions and clauses of the N.I.T. (Notice inviting Tender) and the contract
agreement form, particularly in regard to security deposit, mode of payment for
extra work if any, completion time, guarantee about pipe, valves & others fittings,
water tightness tests, structure stability etc.
3.0 The firms/contractors sometimes ask for advance payment of the value of the pipe,
specials, valves & others through bank against railway receipt. Since this tender is
for a “turn key job” on lump sum basis, such condition of payment would be
principally incorrect and therefore would not be accepted if asked for.
4.0 Some firms/contractors stipulate submission of break up schedule of the payment
after award of the contract. The tenderers are therefore requested to accept the
Break up schedule given in tender document as ANNEXURE “G” .
5.0 The firms/contractors sometimes ask for the refund of security deposit in a manner
and time not in conformity with the provision of the N.I.T. Any such condition of
refund of security deposit shall not be accepted to the department and as such the
tenderers are requested to agree to the condition of the N.I.T. on this behalf.
6.0 It is to clarify that no payment would be made on submission of drawing and design
for civil work and general arrangement drawing for pipe, valves and other fitting.
7.0 The tenderers are advised to keep their offer open for acceptance for a period as
prescribed in the N.I.T. i.e. 120 days from the date of opening of financial Bids.

SPECIAL CONDITIONS
ANNEXURE - ‘E’
DESIGN AND CONSTRUCTION OF R.C.C. ELEVATED
SERVICE RESERVOIRS
Public Health Engineering Department constructs a large number of elevated
service reservoirs in rural areas as, well as in urban areas. Many cases of failure of
these structures have come to the department. To minimise failures, it is extremely
important that a uniform policy with respect to design and construction specifications
of these structures is followed throughout the State so that the quality of
construction is ensured.
Keeping in view the above objective, the following
instructions are issued for strict compliance in future. The authorities responsible for
enforcing these instructions will be the respective Chief Engineers of the zones,
Superintending Engineers of the respective Circles and the Executive Engineers-incharge
of the work.
GENERAL INSTRUCTIONS :
1.0 Elevated service reservoir should be designed to provide architectural appearance
and all the related civil features should be as per appearance.
1.1 The RCC columns supporting to the tank should necessarily be round shape and
not square or rectangular. The top shell i.e. water container must be cylindrical.
1.2 On the bottom floor of the water container cast iron or stainless steel grating should
be provided over the supply outlet and scour outlet. This is essential to prevent any
accident for the labour attending to periodical cleaning of the tanks. One such
accident occurred at Sehore when two persons in succession were sucked in to the
scour pipe, the top of which could not be seen because of calcium deposits due to
regular use of bleaching powder. Cast Iron grating 20x20mm or stainless steel
square 20x20mm can be used with square frames on top of the outlet.
1.3 The over flow outlets should not be connected to the distribution system.
Connection of over flow pipe to the distribution system can result in over filling of the
elevated service reservoir in case supply valves of the distribution system are not
open. The over flow outlet should always be kept open for draining any excess
storage in the tank.
E:\Tanki\Baghera_30.sxw - 51 -

1.4 It is extremely important to make arrangements for supply of sufficient water at the
construction site for curing of the concrete. Continuous and efficient curing is
extremely important for development of good compressing strength in any concrete
structure.
1.5 It is advisable to use metal derived from igneous rock preferably of basaltic of
granite origin. The coarse sand should be free from soil. This can be checked
easily by half filling a transparent glass with the sand sample and the other half by
clean water. Stir the sand vigorously. Silt in the sand can then be easily seen in the
top water portion.
1.6 It is extremely essential the contractors undertaking the work should have a
concrete mixer with them. No hand mixing should be allowed.
1.7 In no case the concrete should be laid without vibration. It is desirable to keep two
concrete vibrators at the construction site so that in case of a break down the other
vibrator can be used. It is desirable that the divisions have with them at least two
concrete vibrators, which is an essential T&P for laying concrete.
