RAJPUR BARRAGE VOLUME-IV (ENCLOSURE-II) DRAWING (TYPICAL)

INTRODUCTION AND CONDITIONS:

The volume contains drawings for having basic ideas about structure to be designed and to be

constructed by bidder. These drawings (Typical) were prepared for Construction of Ambod

(madhavgadh) barrage which is approx 11.00 km from proposed Rajpur barrage. The

Design and drawings were prepared by Central Design Organization, Gandhinagar

NWRWS&KD based on data available and basic information. The EPC contractor must

conduct its own survey, geo-tech investigations, Hydrological studies and furnish its own

design to withstand design flood/check flood and duly vetted. The drawings contain various

components of barrage like: Spillway, Piers, Raft, Abutments, Sidewalls, Cutoffs, Foundation

Details, Launching apron, Protection work for banks etc. The bidder should get basic ideas of the

structure using the drawings and furnish design accordingly.

The design, drawing, sketches, narrations, etc. mentioned in the tender is showing the

NWRWS&KD requirement in respect to size, shape, levels, type and nature of work etc. and is

indicative and it is only for the guidance to the agency. The Agency has to submit his own

survey, design required for the work and is required to be got vetted from the institutions

approved by EIC and the agency has to carry out the work after getting procedure of approval as

decided by the NWRWS&KD.

The contractor shall have to design the proposed structure and its components as per relevant

Indian Standards and provide norms/methods and guidelines provided by of Central Design

Organization, NWRWS&KD, Central water commission (CWC), Central Board of Irrigation

and Power(CBIP), CWPRS and Indian standards.

NOTE: DRAWINGS UNDER THIS VOLUME ARE ONLY FOR KNOWLEDGE

PURPOSE, THE BIDDER MUST DESIGN RAJPUR BARRAGE AND ITS

COMPONENTS BY HIMSELF AND THE DESIGN MUST BE SUCH THAT

STRUCTURE SHOULD WITHSTAND UNDER ALL ADVERSE CONDITIONS THAT

MAY OCCUR AND MUST FULFILL ALL THE CRITERIA FOR DESIGN FLOOD TO

BE PASS EASILY THROUGH GATE OPERATIONS WITHOUT ANY DAMAGES TO

THE STRUCTURE AND OTHER REQUIREMENTS. ANY MODIFICATIONS

SUGGESTED BY ENGINEER-IN-CHARGE AND/OR APPROVAL AUTHORITY AS

PER TENDER CONDITION MUST BE INCORPORATED BY CONTRACTOR AT THE

TIME OF APPROVAL OF DRAWINGS. THE CONTRACTOR MUST TAKE CARE

THAT THESE DRAWINGS MAY NOT BE USED FOR ANY OTHER PURPOSE. ANY

CLAIM BASED ON THESE DESIGNS WILL BE STRAIGHT AWAY REJECTED AS

THESE DRAWINGS ARE ONLY FOR KNOWLEDGE PUPOSE.
