What are the engineering properties needed for stability of highway embankment and cut in clayey soils? Suggest the laboratory test program for their evaluation.

Density requirements of soils are critical to the QC/QA (quality control and quality assurance) of compacted borrows in the construction of earth structures, like earth dams and highway embankments.

a) How the density requirements can be established?

b) Give different methods for the field density check and explain how each works.

The average temperatures (°F) for an 8-day period are: 32,35,34,36,48,43,42, and 40. If the area has an initial SWE of 2.46 in, K=0.06in/deg-day, and a runoff coefficient of CR = 0.5, plot the estimated daily runoff (in) from the watershed and determine the total melt and runoff for the 8-day period.

6.28 Modified You are to determine if exposure by oral ingestion to the chemicals xylene, toluene, arsenic, and hexavalent chromium poses a noncarcinogenic health risk. The chemical-specific reference doses (mg/kg-day) obtained from IRIS are: xylene (0.2), toluene (0.8), arsenic (0.0003), and hexavalent chromium (0.003) Assume a 70 kg individual consumes 2 liters of water per day with these chemicals dissolved at a concentration of 1 mg/L. Determine the HQ for the water.

9) An existing rural freeway in level terrain is to be analyzed to determine LOS using the following information: number of lanes in each direction equals 2, peak hour volume of 2140 veh/h (in the peak direction), 15% trucks, 2% recreational vehicles, PHF = 0.90, lane width = 12 ft, lateral clearance = 10 ft, average interchange spacing is 3 mi.

A warehouse needs 3cfm in a control area. the controlled area is 25ft x 50ft. with a height of 20ft. how many cfm would be needed to reach the goal of 3cfm?

A CAT D7G power shift tracklaying dozer is used in a pushing operation. The dozer is equipped with a straight 7U blade. The material (dry and noncohesive) weighs 100 pcf in the bank state. It is estimated that the material will swell 4% from bank to loose state. The center-of-mass-to-center-ofmass pushing is 250 ft on a 0% grade. The operator will have excellent skill, the job will be performed in good conditions. Job efficiency can be assumed to be equivalent to a 45-min hour. Calculate the dozer hourly production in bcy.

A layer of soft, normally consolidated clay is 15 m thick and lies under a newly constructed building. The overburden pressure of the sand overlying the clay layer is 500 kN/m2 and the new construction increases it by 180 kN/m2. If the compression index is 0.25 and the recompression index is 0.015, compute the settlement of the building. The water content of the clay is 30%, the specific gravity of the soil grains is 2.7, and the clay is fully saturated. Consider a soil element at the middle of the clay layer. The water table is at the top of the clay layer.

a) Compute the settlement (one layer)

b) Compute the settlement by dividing the clay layer into three sub-layers, each 5 m thick. To find the total settlement, find the settlement at the center of each sub-layer. Compare with the settlement found in part a.

c) Compute the settlement (one layer) for an OCR = 1.2 and OCR = 2.0.

A boundary survey is being conducted for a client’s parcel of land. You find and accept a concrete monument for a boundary corner and determine its position to have X and Y coordinates of 3496.45 ft & 9798.03 feet, respectively (Corner A). You also find & accept an iron rod as a corner and determine its position to have X and Y coordinates of 5272.92 ft & 10161.36 feet, respectively (Corner C). You determine that you should replace a lost corner (Corner B) between these accepted monuments using record distances provided on a 1995 survey map. The record distance from Corner A to B is 1405.91’. The record distance from Corner C to B is 1121.30’. What are the coordinates the field crew should use to reset corner B? HINT: You will get 2 solutions using distance-distance intersection techniques. Calculate both solutions but chose the solution that is northeasterly from Corner A & northwesterly from Corner C as your final solution. Also, use Civil 3D to check your answer. Show screenshot of your steps. Hint: by plotting the given coordinates and then using circles with radii, we can determine the intersection points.

Pick a general familiar space and answer the following questions:

a. Describe the current lighting approach, including approximate light levels, availability of daylight, electric lighting approach (type and number of fixtures) and available lighting controls. Discuss whether you think the approach is successful.

b..How do the furniture layout and space finishes add to or subtract from the lighting performance? Does space feel ‘cool’ or ‘warm’, over or underlit.

c. .What improvements might you suggest to improve the artificial lighting quality

d. What improvements might you suggest improving daylighting?

e what improvements might you suggest improving energy efficiency?

Completely and thoroughly explain how a Predetermined Time System, such as MTM or MOST, could be used to establish labor standards for a company that makes any type of metal products. Be specific in your answer and identify as many different specific examples as you can where a Predetermined Time System could be used to establish engineered standards for the different operations that are required to make any type of metal products
