(2d) To complement the new rail-project described in question 2a above, the city public-works department has also engaged your design-&-construct company to complete the work necessary for upgrading-repair to a small stretch of an existing city ring-road, to allow better access to an outlying train-station. You are assigned by the project manager of this road repair project, to lead a team of 5 workers. You are expected to finish all repair work within 15 days, and have been asked by your project manager what you will do to complete the project within the stipulated time. Discuss the measures required to achieve your manager's deadline, in terms of: your definition of quality in this project and what should be included in the quality management plan here; the procedures required for this project development process: what is to be included in your scope-of-works document, your leadership role as it relates to the company's quality policy towards the successful completion of the…

The initial investment for constructing a median and guardrails for a prestressed concrete bridge is $1000000. Maintaining these facilities is expected to cost $2000 annually for the first five years of service and $10000 for the next five years of service. It is expected that these facilities will be rehabilitated at the end of the tenth year at a cost of $60000, after which the maintenance costs are expected to decrease to $6000 per year. What is equivalent uniform annual cost over a 15 -year period of service if the interest rate is 6% per year?
III. A state highway department is planning the construction of a 50 mile, four-lane toll road. It estimates that the construction cost (t = 0) will be $200M and annual maintenance costs will be $IM per year. In addition, every 20 years, a major resurfacing will have to be carried out at a cost of $25M. It is estimated that 6 million cars and 400,000 trucks will use the road cach year, and it is decided that the toll charged to a truck will be 4 times that of a car. The interest rate is 7%. I Determine what the toll should be for each car and truck to cover all expenses for a planning period of 40 years. Assume the toll being charged and the estimated traffic flows do not vary year-to-year.
Answer also given please show the work clearly. Note: kindly answer all otherwise leave it question. Thank you a What is the probability that path A-B-D-F-G will take from 100 to 120 days to complete? Answer = 40.2% b. What is the probability that path A-C-E-G will take less than 85 days to complete? Answer = 32.64% c. If the contract for the above project is 120 days, what is the chance of meeting the schedule? Answer = 86.3% d. What duration (number of full days) should be used to be at least 90% confident of finishing on time? Answer = 125 days - Probability of 93%

List possible costs that may be involved in the transportation construction process.
Three designs have been proposed to improve traffic flow at a major intersection in a heavily traveled suburban area. The first alternative involves improved traffic signaling. The second alternative includes traffic-signal improvements and intersection widening for exclusive left turns. The third alternative includes extensive reconstruction, including a grade separation structure. The construction costs, as well as annual maintenance and user costs, are listed in the following table for each alternative. Determine which alternative is preferred based on economic criteria if the analysis period is 20 years and the annual interest rate is 15%. Show that the result is the same using the present worth, equivalent annual cost, benefit–cost ratio, and rate-of-return methods.
