1) Due to the construction of a building, 150 kPa vertical stress increment takes place in a clay layer. The thickness of clay layer is 8m and there are a very thin sand layer above and a thick sand layer below it. If the final settlement is 0.08m, calculate the followings:

a) Required time in terms of month for 0.04m consolidation settlement

b) Amount of settlement in terms of meter, after 4 months of construction

c) During the construction, a machine is intended to be placed in to the building. However, the machine is sensitive to the settlement and amount of the settlement should not exceed 0.02m after placing this machine. Calculate the required time to satisfy the prerequisite in terms of months.

d) k value of the clay layer

mv = 1*10-4, cv = 0.4 m/month

You are the environmental specialist for a company that has just purchased a property and started construction of a home office. During excavation you find that the site is part of an inactive landfill. Testing of soil samples shows that vinyl chloride, a hazardous waste, is present in concentrations that exceed regulatory standards. What is your next action? If the remediation of the problem is very costly, will you seek participation by other parties? If so, why?

A test of a driver’s perception/reaction time is being conducted on a special testing track with wet pavement and a driving speed of 65 mi/h. when the driver is sober, a stop can be made just in time to avoid hitting an object that is first visible 555 ft a head. After a few drinks under the exact same conditions, the driver fails to stop in time and strikes the object at a speed of 35 mi/h.

Question - 6 Determine the Braking distance for sober driver?

Question - 7 Determine the sober driver perception-reaction distance?

Question - 8 Determine the sober driver's perception/reaction time?

Question - 9 Determine the perception/reaction time of driver after drinking?

A square footing 1.5m X 1.5m is located at a depth of 1.0m. The soil has the following properties: γ = 17.5kN/m3, c= 20kN/m2 and Φ = 34o. The footing base and ground are horizontal. if the horizontal component of the weight = 20kN acting at the height of 4m parallel to the side of footing, and vertical component is 500kN, determine ultimate bearing capacity and factor of safety. using Hansen’s analysis

3. For a dual carriageway new road scheme, the average annual daily flow (AADT) of one way traffic is 24,000; 2% are commercial vehicles. No channelisation is expected to occur. Design a foundation and bound layers of a pavement. The subgrade surface modulus = 40mpa = 4%CBR. State any assumptions made, including the choice of design method and sketch a cross section of the final pavement design.

(N.B. there are hundreds of potentially correct designs depending on the choices of design methods and materials. Any submissions that include identical designs may be investigate for potential collusion).
