Discuss the estimate of an irrigation project (data required and sub-heads to be included in the detailed estimation report). ## Short answer A project is a temporary one-time undertaking with defined objective, scope, budget, schedule, and end. Irrigation estimate needs survey, hydrology, geology/soil, designs, quantities, rates, land/social data, specs and time. Report sub-heads: preliminary, land/compensation, headworks, canals, canal structures, drainage, buildings/roads, electro-mechanical, environmental/social, tools/plant, supervision and contingencies. ## Answer #### Project A **project** is a temporary, one-time undertaking with a defined objective, scope, budget, schedule and a clear start and end, carried out to create a unique product or facility. An irrigation project, for example, aims to bring water to a command area through a diversion weir, canals and structures. #### Data required for an irrigation project estimate 1. **Topographic and survey data:** contour map, longitudinal profile and cross-sections of canal alignment, command area map. 2. **Hydrological data:** river discharge records, flood levels, rainfall, water requirement of crops (duty/delta). 3. **Geological and soil data:** bed material at weir site, soil type along canal, seepage, bearing capacity. 4. **Design drawings:** layout plan, weir and canal designs, drawings of all structures. 5. **Quantities:** earthwork, concrete, masonry, gabion, steel, etc., from the drawings. 6. **Rates:** District Rates, rate analysis and norms of DUDBC/Department of Irrigation, lead and lift for materials, transport, taxes. 7. **Land and social data:** land to be acquired, compensation, crops, forest and environmental clearance, resettlement. 8. **Specifications and time:** construction method, season, work programme. #### Sub-heads of the detailed estimation report | Sub-head | Main items | |---|---| | A. Preliminary | Survey, investigation, design, feasibility study, soil tests | | B. Land and compensation | Land acquisition, trees, structures, forest clearance | | C. Head works | Diversion weir/barrage, intake, under-sluice, settling basin, river training | | D. Canals | Main, branch and distributary canals: earthwork, lining | | E. Canal structures | Regulators, aqueducts/siphons, drops, culverts, escapes, outlets, bridges | | F. Drainage | Field and main drains, flood protection | | G. Buildings and roads | Inspection path, canal roads, office/quarters, gauge posts | | H. Electro-mechanical | Gates, hoists, pump (if any) | | I. Environmental and social | Mitigation, afforestation, user training | | J. Tools and plant, miscellaneous | Equipment, communications | | K. Establishment/supervision and contingencies | Supervision ~3–5%, physical contingency ~5%, price escalation, VAT 13% | The report contains an introduction, abstract of cost, detailed estimate sheets, rate analysis, specifications, drawings and a construction programme. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. Which statement best defines a project? A. A continuous routine operation with no end date B. A temporary, one-time undertaking with defined objective, scope, budget and schedule that creates a unique facility C. Any construction work costing above a fixed amount D. A set of drawings and specifications only Answer: B. A project has a clear start and end and creates a unique product. (Key point: Definition of project) 2. Why is hydrological data needed for an irrigation project estimate? A. It decides the rate of labour B. It gives the bearing capacity of soil C. River discharge, flood levels and crop water need (duty/delta) decide the weir, canal and structure sizes D. It fixes the VAT rate Answer: C. Hydrology governs design of headworks and canals, which governs quantities. (Key point: Hydrological data) 3. Which sub-head covers the diversion weir, intake, under-sluice and settling basin? A. Canal structures B. Drainage C. Buildings and roads D. Head works Answer: D. These river-side structures form the head works sub-head. (Key point: Head works) 4. Which additions appear in the final sub-head of the irrigation estimate? A. Supervision (~3-5%), physical contingency (~5%), price escalation and VAT 13% B. Only profit of 10% C. Only land compensation D. Depreciation and interest on loan Answer: A. These are added to the total of the items to give the project cost.
