The <strong>Bid</strong>der shall also furnish the details of foundation of the electrical Panel Board,<br />
pipes, valves and special etc. The <strong>Bid</strong>ders are advised to give a confirmation on<br />
clear term that the layouts are acceptable to them fulfilling all technical<br />
requirements of their offered equipments. The equipment layout details, data etc.<br />
are to be clearly incorporated in the layout drawings by the <strong>Bid</strong>ders and are to be<br />
submitted along with the offer.<br />
23.4 Information to the <strong>Bid</strong>ders to work out the system.<br />
The following factors are to be considered in design and selection of pumping<br />
machineries :<br />
Daily demand of water = 4.36mld.<br />
Hours of pumping = 20 Hrs/Day.<br />
RL of water level at the<br />
Clear water RCC sump = 1772.00+ water level in the<br />
sump.<br />
Dia of rising main = 0.30m<br />
Length of rising main = 6750Rm.<br />
Material of rising main = DI pipe.<br />
RL at point of discharge<br />
(site for construction of Reservoirs) = 1935.00m<br />
Number of pumps to be installed = 2 Nos.<br />
Duty pump = 1 No.<br />
Standby pump = 1 No.<br />
Type of liquid to be pumped = Clear water.<br />
In the design selection of pumping machineries for Intermediate pumping station,<br />
the following conditions are to be taken into consideration.<br />
The datas given above with reference to RL are indicative and are not to be<br />
considered as final. After finalisation of tender, if any change in the site, RL s,<br />
resulting in change of operating head of the pumps, the contractor should arrange<br />
design & selection of pumping plant/machineries for approval by the department<br />
before proceeding for order of the same. The contractor are required to visit the site,<br />
conduct survey, collect necessary datas required in designing and selection of<br />
suitable pumping plant/machineries. The detail design calculation including<br />
selection of type of pumps, motor, motor control center including type of starters,<br />
cabling and valves inside the pump house viz. Sluice/butterfly valves and Nonreturn<br />
valves are to be furnished along with the tender.<br />
