Double levellingwithautolevel,fortransferofbenchmark,recording levels at 30 meter interval and marking temporary bench mark at suitable location. Level book, bench mark value and locationand plotting of the survey data is to be submitted to the department In Plain area

Digitization of Khasra map with details in layers and providing soft copy (a cad file)

Survey work of existing dam taking level @ 30 meter longitudinal spacing for L-section and 5 meter transverse spacing for X-section and preparation of L- section showing top of embankment, u/s & d/s toe level, sluice, spilling arrangement of existing dam and X-sections indicating location and extent of pitching, sluice, face wall, filter toe, berms etc. To prepare and provide top plan and X-section section of existing spilling arrangement (overflow/by wash) showing details of protection works/aprons, training wall, guide wall with block level [plan with levels @ 10 meter grid covering 50m u/s and 100m d/s area. Listing of visible distress in dam -section and spill and sluice arrangements is to be provided with this survey. Drawing of plan and sectional elevation of existing sluice, indicating u/s approach well, barrel and d/s toe wall up to joining of main canal indicating gate/operation system arrangement.

(a) Height of Dam less than 10 meter from lowest nalla bed (For existingDam)

(a) Height of Dam More than 10 meter from lowest nalla bed (For existingDam)

Survey work with total station and preparation of L- section showing level @ 30 meter and X-section with levels at suitable interval clearly showing shape of canal, X-section should be extended both side 10m beyond bank toe/borrow area. The location of C.D. works direct out lets (with size & nos.) / cuts, regulations and existing lining (type and extent) be marked (this shall be done separately for each main canal, branches/minors/sub minors). Listing of present status of existing structures and lining reaches indicating visible distress conditions complete in all respect with material including jungle clearance required for survey work. Digital plotting of drawings with scale 1:2500 (H) and 1:100 (V) for L-sections and 1:100 (H&V) for cross sections for main canal / branches and 1:50 for distributaries and minor/sub-minors including all ancillary works as described in specifications and conditions of contract.

(a) For Existing canal having discharge up to 10 cusec

(b) For Existing canal having discharge >11 & up to 25 cusec

(c) For Existing canal having discharge> 26&up to 100 cusec

(d) For Existing canal having discharge> 101 & up to 200 cusec

Computation of peak flood, routed flood and checking of the adequacy of flood discharge, capacity of existing spill arrangement.In case of existing spill arrangements are found inadequate, the alternative proposals for increasing spill capacity without changing the existing MWL or encroaching the free board besuggested.

Based on the existing cropping pattern, water availability, suitable percentage of cropping pattern to be suggested after getting approval from District Agriculture officer and crop water requirement data / water allowances, finalize the duty and computing B.C. Ratio of the Project

Preparation of draw-off statement/design of canal section and all structures and if modification needed anywhere be suggested and incorporating it in preparation of draw-off statement, design, drawing etc for complete canal system in all respect with material.

Conducting a joint meeting and walk through survey with department, WUA and E&M consultant computing the list of works required to be executed for improvement of overall irrigation efficiency and finalization of the list in general body meeting of WUA and tentative rehabilitation (remedial and improvement measures be suggested for preparation of Draft Detailed Project Report).

Preparation and submission of final Detailed Project Report for rehabilitation of minor irrigation projects incorporating suggestion / observation of approving authorities pointed out on draft report in three set of hard copy with drawings and soft copy.
