- Suppose that you are a Project Engineer on a Dam project. The volume of soil required at the dame site is Vd=100,000m3. The final void ratio (ed) is 0.80. Your boss, the Project Manager delegates to you the important decision of buying the earth fill from one of three suppliers. • Supplier X sells fill at OMR. 0.200/m3 with e = 0.90• Supplier Y sells fill at OMR. 0.120/m3 with e = 2.00• Supplier Z sells fill at OMR. 0.150/m3 with e = 1.60Evaluate and select the best supplier based on your knowledge about soil compaction.A fill of volume 150000 cum is to be made of void ratio 0.8. The void ratio of borrow pit soil is 1.4. Find volume to be extracted.Q5-A proposed earth dam requires 7500 m³ of compacted soil with relative density of 94%, maximum void ratio of 0.73, minimum void ratio of 0.4 and specific gravity (Gs)= 2.67.

- You have been hired as a project Engineer for a development company in Namugongo to build 610 housing units. Since the original ground is low, you need fill material to raise the ground level. Your estimated fill requirements are 700,000m3 with a void ratio of 0.46. the insitu material at the borrow pit has a void ratio of 0.39 where as the material dumped in trucks has a void ration of 0.71. How many trucks will you need, if each truck carries 10m3? i will need all the work outs in full and well explainedA fill having volume of 150000 m³ is to be constructed at a void ratio of 0.8. The borrow pit solid has a void ratio of 1.4. The volume of soil required to be excavated from the borrow pit will be (a) 150000 m³ (c) 250000 m³ (b) 200000 m³ (d) 300000 m³Q: A proposed earth dam requires 7500 m of compacted soil with relative density of 94% , maximum void ratio of 0.73, minimum void ratio of 0.4 and specific gravity (Gs) = 2.67.

- GEOTECHNICAL ENGINEERING: The Undisturbed soil at a given borrow pit is found to have the following parameters. The water content is 15%, the void ratio is 0.60 and the specific gravity of the solids is 2.70. The soil from this borrow pit is to be used to construct a rolled fill having a finished volume of 50,000 yd3 . The soil is excavated by means of a shovel and dumped on trucks. When loaded to capacity these trucks are found to contain, on average, a net weight of wet soil equal to 13,000 lbs. In the construction process, the trucks dump their load on the fill, the material is spread and broken up, after which a sprinkler adds water until the water content is equal to 18%. The soil and water are thoroughly mixed by means of dicers (or other similar equipment) and then compacted until the dry unit weight γd=110 lbs/ft3. Helpful Conversions (3ft=1yd), (γw=62.4 lbs/ft3), (7.48gal/1ft3 ) a) If the fill should become saturated at some time subsequent to construction and does not change…GEOTECHNICAL ENGINEERING: The Undisturbed soil at a given borrow pit is found to have the following parameters.

A highway fill is being constructed using the soil from this borrow at a dry unit weight of 18.05 kN/m³ • Find the volume of the borrow pit that would make one cubic meter of the finished highway fill. Answer: 1.136 m3
- Your company has won a contract to provide and compact the fill material for an earth levee (an embankment built to prevent overflow of a river), with the dimensions shown below. The levee fill is a silty clay soil to be compacted to atleast 95.1% of maximum standard Proctor of dry unit weight= 109lb/cu.ft at an OMC of 18.6%. Your borrow pit has a silty clay with an in-situ moist density of 112.6lb/cu.ft at 18.1% water content and a Gs = 2.679. When the soil is excavated and loaded on to your trucks, the void ratio of the material is e = 1.46. Your trucks can haul 401 cu.ft of material per trip. DETERMINE THE FF AND SHOW COMPELETE SOLUTION. ALL FINAL ANSWER WILL BE IN 3 DECIMAL PLACES. 1. Determine the volume of fill required for the levee in cu.ft 2. Determine the volume required from the borrow pit in cu.ft 3. Determine the required number of truck loads.Consider a soil that is being placed as a fill and compacted using a sheepsfoot roller (a pieceof construction equipment). Will the action of the roller change the void ratio of the soil?Explain.A proposed earthen dam will contain 5,000,000 m3of earth. Soil to be taken from a borrow pit will becompacted to a void ratio of 0.78. The void ratio ofsoil in the borrow pit is 1.12. Estimate the volume ofsoil that must be excavated from the borrow pit. Include phase diagrams.
