please solve part 2

You were assigned as a project manager for a residential project in North Lebanon. You estimate that the plot will require somewhere between 10,000 square meters and 12,000 square meters of land. The building will have a foot print of 8,000 meters. The rest will be used for gardening and planting trees. You want to benefit from the current LBP conditions and would like the project to be done before 2025. You envision a five story building and a penthouse. The garden will include orange and cherry trees with some bushes. The building will have upscale electrical and mechanical finishing. The super structure will be made from RC with an outside cladding of natural stones. Many of the materials will be imported from outside the country and this might add extra risks due to the political and health conditions globally and in Lebanon. 1- Make all the assumptions you need to plan the project using the following activities: Excavation, foundation, super structure, electro mechanical works, finishing 2- Using justified one point estimates provide the overall duration of the project 3- Using a PERT distribution provide the estimate duration for the project 4- Estimate the duration of the first floor only, then use learning curves to estimate the duration of the project 5- Conduct research to estimate the cost of the following: Excavation, concrete (assume a total quantity of (5,000 cubic meters), Gardening and landscape (Assume quantity of trees) 6- Conduct an economic assessment to evaluate the impact of various exchange rates on the NPV and IRR of the project 7- Couple the previous part with your judgement to decide on whether this project should go on You were assigned as a project manager for a residential project in North Lebanon.
