equipment load data as may be required for civil construction shall also be arranged<br />
by the contractor from the pump manufacturer. The offered pumps motors and other<br />
equipments shall match the stated requirements (foundation plan, total available<br />
floor area, minimum height of crane with minimum hook clearance over floor etc.)<br />
as shown in the layout drawing and a line of confirmation for the same shall be<br />
furnished with the technical offer.<br />
The H.T/L.T. Power, control and signal cables from the respective switch/breaker/<br />
electrical outlets shall be partially within metallic tray/hangers in the pump house<br />
enclosure. All cable laying, supply, fixing of cable trays/hangers as required shall<br />

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 />
