<br />I <br /> <br />G. <br /> <br />40 <br /> <br />4. Structure PlanS <br /> <br />A description of proposed major structures and <br />typical minor structures. <br /> <br />a. Profile and typical sections of canals, giving <br />dimensions, hydraulic properties and water <br />surface or hydraulic gradeline elevations. <br /> <br />b. Layout and sections of each major structure and <br />typical minor structures, showing important dimen- <br />sions and hydraulic properties. <br /> <br />5. Drainage <br /> <br />A description of any present or anticipated drain- <br />age problems and plans for their correction. <br /> <br />6. Sedimentation <br /> <br />A description of effect suspended solids and bed- <br />load may have on project facilities and what provisions <br />will be made to minimize the effects. Also, estimate <br />of sediment storage required and determination of ele- <br />vation of reservoir outlet. <br /> <br />7. Right-of-Way <br /> <br />A discussion of right-of-way requirements; right- <br />of-way available; and if additional right-of-way is <br />required; proposals for such acquisition. <br /> <br />,Estimated Costs <br /> <br />1. Costs of Construction <br /> <br />The chapter will include: <br /> <br />a. Derivation of unit construction costs and <br />pertinent factors affecting estimated <br />construction costs. <br /> <br />b. A tabulation showing the quantities, unit <br />cost, and total cost of each type of work <br />or material for each major structure and each <br />class of minor structures. <br /> <br />c. A summary of estimated project costs. <br /> <br />d. The allowance for contingencies that was <br />included in the cost estimate. <br /> <br />fE')OC1~ <br />b~Hj\JU\w <br /> <br />5 <br />
